* The battery is optional and is
not fitted in all applications.
Board 1 must be fitted at the bottom of the stack and where
both LMU I/O boards and Bus / MOVA I/O boards are
required, the LMU I/O boards must be fitted first. However, early versions of
the OMCU were arranged with I/O board 1 at the top – no change is required to
these units.
Important
The Siemens Traffic Outstation provides a number of different facilities depending on
the firmware fitted:
PB680 firmware provides the RMS OMCU, DUSC, Flow, Occupancy, OMCU Events
and Switch Override, and Bus Processor applications or the Car Park Count
application.
PB681 firmware provides the Siemens TRL MOVA application along with the RMS
OMCU and Bus Processor applications (in issue 10 onwards).
The RMS OMCU application monitors TR0141 intersection and ‘mid-block’ (or
‘stand-alone’) pedestrian controllers and most pre-TR0141 traffic controllers. It
reports back faults and status of both the Traffic Controller and the OMCU itself to
the Instation. The configuration for the intersection to be monitored is downloaded
from the Instation to the OMCU. See section 4.1 for more information on the OMCU
application.
The DUSC application has the same facilities as the RMS OMCU application, but
can also control traffic controllers via timetable events (e.g. Introduce a plan at 9am
667/HB/26568/000
Page 12
Issue 15
3U Traffic Outstation Handbook
on Monday, and isolate the plan at 6pm on Friday). See section 4.2.9 for more
information on the DUSC application.
The Flow application can be connected to up to 16 detectors. Each detector can
provide flow data over a configured period of time. If the flow data meets the ‘up
threshold’, a flow alarm is raised. If the flow data meets the ‘down threshold’, the
flow alarm is cleared. Flow data is stored in the ‘Operations Log’, and can be
uploaded to the RMS Instation. See section 4.2.10 for more information on the Flow
application.
The Occupancy application can be connected to up to 16 detectors. Each detector
can provide occupancy data over a configured period of time. If the occupancy data
meets the’ up threshold’, an occupancy alarm is raised. If the occupancy data meets
the ‘down threshold’, the occupancy alarm is cleared. Occupancy data is stored in
the ‘Operations Log’, and can be uploaded to the RMS Instation. See section 4.2.11
for more information on the Occupancy application.
There are up to 16 OMCU Events, which are inputs to the OMCU and 16 Switch
Overrides, which are outputs from the OMCU. The OMCU Events are monitored and
when they meet predefined conditions a message is sent to the Instation. The
Instation can then make a decision as to whether a new plan and/or switch should be
introduced (Switch Overrides). By adjusting plans and/or switches at adjacent traffic
junctions the traffic flows within an area can achieve an increased flow capacity.
Switch Overrides are activated by the Instation when an OMCU Event has been
reported. A Switch Override will remain active for a fixed period of time, or until
cancelled by the Instation. See section 4.2.12 for more information on the OMCU
Events and Switch Overrides.
The Bus Processor application can be connected to up to 12 SIETAG readers and
provides both logging and access control functions. See section 4.2.5 for more
information on the Bus Processor application.
The MOVA application is a new strategy for control of traffic light signals at isolated
junctions. See section 9 for more information on the MOVA application.
The Car Park application determines the current occupancy of a car park and sends
this to a ‘SIESpace’ Instation over a PAKNET communications interface. This
information can then be used by the Instation to guide vehicles to car parks that have
spaces. See section 10 for more information on the Car Park application.
All of the applications within a unit (except the Car Park application) can be used
simultaneously; limited only by the number of I/O boards that can be accommodated.
The hardware platform is a self contained unit consisting of a CPU board that is
microprocessor based, one or more I/O Boards, the PSU, and optionally a Modem
and Battery if required (see Figure 1 overleaf).

3U Traffic Outstation Handbook
Where a Modem is present, it can be connected through a land line to the PSTN or
via a GSM 900 digital network. The unit can be communicated with and will report
back faults via the PSTN or GSM. When a modem is not present, all Instation
functions are available locally via a local RS232 ‘handset’ port. The platform has the
facility to share a PSTN connection with other compatible equipment. The GSM
version of the unit is available for situations where a PSTN connection is not
available or is not cost effective (see sections 2.6.2 and 4.2.9).
The unit is mains powered and can be fitted with a battery to support the unit in the
event of a mains failure, which allows it to dial the Instation to report the mains
failure.
The complete unit fits within a Traffic Controller’s Roadside Cabinet. It is designed to
fit within an existing 3U detector rack, in an additionally supplied 3U rack, or directly
onto the rack mounting uprights. It can be mounted in an Ancillary housing if
necessary.
When fully configured it occupies 192mm of a standard 3U rack, and is of a modular
design. The boards are interconnected by way of an expansion bus and up to 3 I/O
boards may be fitted. The main features of each individual board, assembly and the
expansion bus are highlighted in the following sections.
This Unit meets all the Environmental and EMC requirements as specified in section
2.3 of MCE 0152A, and specifications TR2130A and TRG1068A.
2.2 Siemens Traffic Outstation Equipment
The Siemens OMCU (667/1/28850/000) together with the OMCU cables
667/1/28852/000, is capable of monitoring a Traffic controller with up to 16 phases
and up to 48 digital inputs. It can also control a number of isolated outputs.
The OMCU normally uses one or more LMU I/O boards each providing up to 10
lamp monitor channels, 16 digital inputs, and 4 digital outputs. An alternative I/O
board providing 4 RS485 communication channels, 48 digital inputs and 16 digital
outputs may also be fitted. This board is primarily used by the Bus Processor and
MOVA applications and thus is known as the Bus / MOVA I/O board.
A number of optional kits are available which, when added to the Basic OMCU, allow
connection to any Controller. MOVA and BUS Processing kits are also available. The
sections 2.2.1 to 2.2.3 that follow show the combinations of facilities and the way the
components are connected.

multi-layer PCB, using mostly surface mount components. It provides the processing
power required by the unit. The processor unit is based on IBM's Power PC range of
32-bit microprocessors (403GA) with highly sophisticated on-chip peripheral
capabilities. This, along with the dual channel communications device (Siemens
ESCC2 SAB82532-2) and an extensive use of surface mount devices has ensured
denser system construction, with high performance.
The board provides the expansion bus that extends the system using one, two or
three I/O boards. For details see section 2.8 on page 21.

multi-layer PCB, using mostly surface mount components. When required for OMCU
monitoring, up to three LMU I/O boards may be fitted to meet the entire controller's
monitoring requirements. I/O boards access the processor board by way of the
Expansion Bus, see section 2.8 on page 21 for more details.
This board provides the power for the modem, with a choice of three different
voltages offered.
A Zero Cross Over circuit provides timing to the software, for the mains based
monitoring signals.
Finally there is a modem sharing circuit which allows two systems within the
controller cabinet to share a modem to the PSTN.

2.5 BUS / MOVA I/O BOARD
This is a 3U 220mm long, 100mm wide and 18mm high extended Eurocard. It is a
multi-layer PCB, using mostly surface mount components. When used for Bus
Processor or MOVA applications, the unit can be fitted with up to three Bus / MOVA
I/O boards. If OMCU monitoring functions are also required, then a mix of LMU I/O
boards and Bus / MOVA I/O boards can be fitted. I/O boards access the processor
board by way of the Expansion Bus, see section 2.8 on page 21 for more details.
667/HB/26568/000

Issue 15
3U Traffic Outstation Handbook
This board provides four RS485 communications links enabling communications with
RS485 based equipment such as SIETAG and optionally the GPS receiver.
The 48 digital inputs and 16 digital outputs meet the TR0141 specification and thus
provide MOVA and DUSC with its stage force bit outputs to, and confirm inputs from,
any traffic controller configured with a UTC/MOVA/DUSC interface. It also provides
MOVA and DUSC with its detector inputs that can be connected in parallel to the
controller.
This board also provides the power for the modem, with a choice of three different
voltages offered. Unlike the LMU I/O board which uses one of its digital output relays
to switch the modem power, the Bus / MOVA I/O board has this switching capability
built in.

2.6.2 The GSM TC35 Modem Unit (option)
This replaces the M20 GSM Modem which is lo longer available.
This modem is a dual band GSSM900/1800 unit but limitations of the aerial restrict
it’s use in this application to the GSM900 network (Vodaphone or Cellnet).
To use the GSM OMCU the Instation must be equipped with the PACE PCM33.6 or
the Dynalink PK5-5600 Modem. See section 8.4.3 for compatibility details. Note that
new or additional Instation modems may be required to support the GSM OMCU
alongside other 5U and 3U units.
The user is responsible for setting up airtime agreements with their chosen network
supplier, ensuring that there is adequate signal coverage at the site and obtaining
the appropriate SIM card, which must be as follows:
SIM Card
3V type
Phase 2
Data only
PIN Disabled
If a GSM OMCU is used, an aerial must be fitted close to the Controller. The aerial
feeder is a fixed length of 15 metres. Where no signal pole is available within
approximately 8 metres of the controller cabinet, suitable aerial mounting
arrangements will need to be provided.
The OMCU firmware should be PB680 issue 7 or later.
There is one LED on the TC35 GSM unit. When the TC35 is powered the LED will
flash; the LED comes on permanently once a GSM service is recognised.
See drawing 667/CF/26598/010 in Appendix B for installation and set-up instructions.
Note that the issue of the TC35 firmware must be 4.0 or above. To determine the
issue of the firmware connect the 9 pin port on the TC35 to a PC serial port running
a terminal emulator. Set the PC to 2400 bits per second, 8 bits no parity, 1 stop bit.

2.7 THE POWER SUPPLY UNIT (PSU)
This is a 127mm long, 76.2mm wide and 37mm high OEM unit, which supplies the
system with +13.65V. The OMCU uses an optional float charged battery held within
the PSU case to provide total system backup in the event of mains’ failure.

2.8 THE EXPANSION BUS
This is a set of 64 way plugs and sockets. Each board in the system has a connector
fitted that passes through the PCB and becomes a socket on the component side
and a plug on the solder side. The boards connect using these sockets and plugs
through an additional connector, starting with the processor, by plugging an I/O
board into its socket, then an I/O board into the I/O's socket and so on.
All boards provide buffering for Address, Data and Control signals and also distribute
the logic supplies.

3. SPECIFICATIONS
3.1 INTRODUCTION
The following sections describe the full Electrical, Mechanical, Environmental,
Isolated Outputs, Isolated Extra Low Voltage Inputs, Isolated Low Voltage Inputs,
Analogue Inputs and Communications specifications of the unit.
3.2 ELECTRICAL
3.2.1 Mains Supply
Normally the unit is powered from an auxiliary mains supply provided within the
controller. In controllers without this facility or if this is not convenient, a suitable
alternative mains supply must be provided, being careful not to compromise the
safety of the controller (Refer to Engineering if in doubt).
Voltage: 230V AC RMS, +15% to -20%
Frequency: 46 - 54 Hz
Mains fused: The recommended rating of this external fuse is 2A anti-surge.
(The mains cable is rated to 6A, fuses up to 5A may be used)
3.2.2 Power Supply
The unit incorporates its own internal power supply unit that provides the necessary
supply voltages to all of the boards and assemblies associated with the complete
unit. The boards are designed and implemented to operate from a single voltage
regulated supply.
Output Supply: Regulated 13.65V DC
Rating: 3.15A
Powering: Processor board, I/O board(s), Modem and Charging the Battery
3.2.3 Power Dissipation
Low power CMOS devices are used throughout the unit to keep the power
dissipation as low as possible.
Total power consumption: 8.0 W typical (using maximum configuration of 3 I/O
boards and battery float charging)
667/HB/26568/000

3U Traffic Outstation Handbook
3.2.4 Support Batteries
The unit can be fitted with two rechargeable batteries.
The first is the optional Unit Support Battery, which supports the entire unit including
the modem, for a minimum of four minutes under all conditions in order that the
OMCU may inform the Instation of a mains power failure.
Note that some units, e.g. MOVA only units, do not require and will not be shipped
with a Unit Support Battery.
The other, the RAM Battery, is always fitted and supports the RAM memory and the
Real Time Clock during power failures for an excess of 7 months. On Issue 4 and
later CPU boards this battery is plug-able to allow easy replacement.
Newer processor boards include a ‘Gold Cap’ capacitor that allows the RAM battery
to be changed without loss of RAM data. The Gold Cap device provides a minimum
of 30 minutes support.
The two batteries have the following specifications:
Battery

In excess of 7 months after
Nickel Metal Hydride
the Unit Support battery of 20
418/4/39820/000
minutes has expired.
3.3 MECHANICAL
The construction of the unit is based on the standard 3U high, IEC297 Eurocard rack
system. The unit does not use the conventional back plane approach. Instead it uses
an expansion bus (see section 2.8 on page 21), to interconnect the boards
electrically. It does not require the rack to have guide rails, but if present they need
to be on 25.8mm spacing. Mechanically the boards are held in a stack, by four sets
of pillars and fixings, and held in place on a mounting plate. The mounting plate, also
accommodates the Modem and PSU assemblies, and is used to fix the total unit
assemblies to the 3U rack, or cabinet mounting side angle bracket.

3.5 ISOLATED OUTPUTS
The I/O boards are each equipped with a number of relay isolated outputs, four
normally open contacts on an LMU I/O board and 16 change-over contacts on a
BUS / MOVA I/O board. The following describes the electrical characteristics of
these outputs:

Only the last three outputs on each LMU I/O board have the series
resistor fitted. The first output is used to control the modem power (on
the first board only) and so has no series resistor.
The last two isolated relay outputs (circuits 15 & 16) have a switch that
enables the resister value to be selected as either 182Ω or 22Ω (this
allows for different applications).
The continuous current sink is limited by the resistors.
3.6 DIGITAL INPUTS
Each LMU I/O board supports 16 fully software configurable photo-coupled extra low
voltage isolated digital inputs and each BUS / MOVA I/O board supports 48 TR0141
compliant digital inputs. These digital inputs have the following input electrical
characteristics:

Each of the LMU I/O board inputs employs an opto Isolator, with additional circuitry
to protect against reverse voltages and a degree of current limiting. The inputs are
polarity sensitive and one polarity sense give 5V working whilst the other gives 24V
working. Also see 5.6.4) Digital Monitor Connections (LMU I/O Board Only).
667/HB/26568/000
Page 24
Issue 15
3U Traffic Outstation Handbook
3.7 ISOLATED MAINS VOLTAGE INPUTS
Each LMU I/O board also supports 10 fully software configurable photo-coupled
mains voltage inputs and a fully configured OMCU provides 30 such inputs. The
function of these inputs is to provide an isolated means of detection of the presence
or absence, of the mains’ signal at the phase drive output terminal blocks. The
following describes the electrical characteristics of a single input.
Each of the inputs again uses an opto Isolator, with additional circuitry, to protect
against reverse voltages, to allow a wide range of mains inputs (including 50 - 0 50V AC working for Welsh Office application), also provides current and voltage
limiting.
The High Voltage inputs have the following input electrical characteristic:
Input Impedance: 99kΩ
Absolute Max. Applied Voltage: 580V RMS
Min. Voltage to guarantee signal on condition: 40V RMS
Isolation Voltage: 2500V RMS
3.8 ANALOGUE INPUTS
Each LMU I/O board supports 10 fully software configurable analogue inputs. The
function of these, when connected to appropriate current sensing toroidal
transformers, is to measure the current supply to the lamps, or when connected to the
appropriate voltage monitor transformer, measures the true level of the lamp supply
voltage (dim or bright). The following describes the electrical characteristics of a
single input.
Each of the inputs is multiplexed to an analogue to digital converter. The analogue
inputs are designed to work with both the current sensing transformer that will
measure currents from 0A to 6A peak (and will accept short term current flows of
12A) and the Voltage monitor transformers, which will measure voltages from 0 to
276V.

Voltage monitor:
6A peak
9V peak to peak @ nominal mains
3.9 COMMUNICATIONS
The processor board contains three serial RS232 communications interfaces and the
first LMU I/O board contains a forth. Each Bus / MOVA I/O board contains four
RS485 communications interfaces which are described on the following page.
These interfaces are fully software programmable in terms of their transmission
characteristic. The first RS232 Channel has the additional facility in that it can be
software configured on the direction of the RS232 interface, i.e. DCE or DTE, in this
application it is permanently configured as a DCE in order to connect to a controller’s
141 handset port.

Any fault detected is logged and reported to the Instation identifying the type (i.e.
signal lamp or detector, etc.) and location (i.e. Phase A-RED or stage 2 demand,
etc.).
Some reported faults are automatically 'cleared' by the OMCU itself; others can only
be 'cleared' by manual means at the Instation. The following lists indicate which
reports clear automatically.
In addition to the OMCU Fault Log, an Operations Log is also maintained which
records all activity related to Vehicle Classification, Bus / Access control actions,
Flow statistics and Occupancy statistics. This may be interrogated locally at the
OMCU or uploaded to the Instation for further analysis.

4.2.5 Bus Processor Functions
When used for Bus Processor applications, the unit can be connected to up to 12
SIETAG readers (see section 5.6.6 for wiring) to provide both logging, priority and
access control functions.
Vehicles to be given access/priority are fitted with an electronic tag that may be
programmed with, amongst other things, vehicle operator identification and individual
vehicle number. A loop is located in each access lane, which is used by a reader to
interrogate tags as they pass over. Data from the tags is filtered by the outstation
which will log the information and can be programmed to output access requests to
barriers or other equipment such as Traffic Controllers, via up to 16 isolated relay
contacts (expandable to 48 with additional I/O boards).
Several levels of filtering may be configured in each outstation. Filtering options
range from specific access just for uniquely identified vehicles through to all vehicles
of a particular operator. Access may be restricted by time of day and individual or
groups of vehicles may be blacklisted.
The Bus processor is also able to interface to certain City of London (TCSU) bus
priority beacons and provides similar facilities to those described for SIETAG above.
The following version of firmware is required for the standard Bus Processor
functionality.

Figure 7 – SIETAG OMCU to OTU
The Bus processor may be locally configured via the handset (LDV=4) to route
SIETAG vehicle detections through the 141 serial port to an OTU as a sequence of
13 GED environmental sensor commands. Each set of 13 commands comprises of
the original 8 bytes of the vehicle detection, prefixed by a time stamp and the
identification of the SIETAG reader that supplied the detection. The SIETAG reader
identification must be configured by the user via the handset (using the BID handset
command - see section 11.10), otherwise a default of 0 is returned for each vehicle
detection, irrespective of the SIETAG reader that supplied the vehicle detection.
NOTE: The Loop number supplied with vehicle detections from V3.3 or later SIETAG
readers is not supplied to the OTU.
The data byte accompanying each command is decoded by the OTU and relayed as
16 reply bits to a UTC Instation where the information can be used for applications
such a travel times analysis.
This facility uses the standard 141 serial cable 667/1/26579/000 to connect the unit
to the OTU handset port.
Once the OMCU - OTU cable is connected and LDV=4 entered, the XXC command
can be used to gain access to the OTU handset (XXO is used to revert to the OMCU
handset).

4.2.6 ST800 Enhanced Link
The ST800 enhanced serial link provides a new high data rate link over the standard
141 cable between the Siemens ST800 traffic controller and the Siemens 3U Traffic
Outstation. This link allows the two units to continuously communicate with each
other in order to provide a more integrated overall traffic product.
Normally, a Siemens 3U Traffic Outstation requires lots of wires to be connected to
various points in the traffic controller to allow the OMCU to monitor and control the
controller. This new enhanced link has removed the need for much of the wiring and
less wiring not only simplifies the installation, but also should provide a more reliable
product – fewer wires mean fewer connections that can fail.
As a more integrated product, the traffic controller provides some of the facilities that
previously only the OMCU could provide. The controller performs the lamp
monitoring and detector fault monitoring, passing any fault information to the OMCU
for reporting to the RMS Instation. The controller’s digital inputs and mains states,
667/HB/26568/000
Page 32
Issue 15
3U Traffic Outstation Handbook
etc. are also passed over the serial link allowing the OMCU and MOVA applications
to read them as though they were connected directly to the unit.
For more information on MOVA using the enhanced 141 link, see section 9.6.4 on
page 117.
The OMCU enhanced 141 link is configured on RMS screen 010, by selecting the
Monitoring Type as “Serial” rather than “Full” when the controller type is “800P”. The
ST800 traffic controller itself does not need to be configured to enable the enhanced
serial link to the OMCU application.
However, the ST800 traffic controller needs to be configured to use ‘Serial MOVA’
rather than its normal digital I/O UTC interface. Also, the “MIO” handset command
may be required to configure MOVA to use the enhanced 141 link rather than its I/O
board. Again, see section 9.6.4 on page 117 for more information on MOVA and the
enhanced 141 serial link.
The facility uses the standard 141 serial cable and requires the following firmware
issues or later – check using the PIC handset commands on the controller and on
the 3U Traffic Outstation:
3U unit firmware
For OMCU (and not MOVA): PB680 issue 8 or later
ST800 firmware
PB800 issue 5 or later
For MOVA, with or without PB681 issue 10 or later
OMCU:
PB800 issue 14 or later
The OMCU handset command EEL can be used to examine the state of the
enhanced link (see section 11.8 on page 179).
When the enhanced ST800 link is enabled, the OMCU handset commands operate
as described below (any commands not listed operate as before):
Command
Operation (when enhanced link enabled)
LMR, KAC,
KLS, KAS
These commands are inactive - use the corresponding lamp monitor
commands directly on the controller.
KDB

received via the serial link.
KLM
Displays the lamps’ on/off state as received from the controller via
the serial link. The OMCU reverts to using the state of its second
mains’ state input, if the controller link fails. If the mains state input is
not connected and the link fails, then ‘lamps off’ is reported.

4.2.7 Car Park Count Detection
A mechanism is provided to enable car park occupancy to be determined.
A total of 10 detector loops can be connected to the OMCU. These are configured as
either car park entry or exit loops. The occupancy of the car park is determined by
the difference in the number of vehicles entering and exiting the car park.
See section 10 for more details.
The following data is transmitted to the Instation:
• Car park Occupancy
• Failed Detector Loops (both stuck active and inactive)
• Power Fail
• Cabinet Door open
• Car park state (Full, Almost Full, Empty or Closed)
• Loop Counts
4.2.8 PAKNET interface
When the OMCU is being used to detect car park occupancy, the information is
passed back to the SIESpace Instation via a PAKNET interface, rather than using
the PSTN.
PAKNET is Vodafone’s packet data network. This is connected to the Instation via a
‘Radio-Pad’, which is an asynchronous terminal device that replaces the modem on
the OMCU.
4.2.9 DUSC Facility
The DUSC facility is very similar to CLF used in the ST800 traffic controller, whereby
plans are introduced at specific times of day and each plan cycles through a
configured sequence of groups in a repeating cycle. At each configured group time
within the cycle, the OMCU activates the specified outputs to influence the controller
movements (See DUSC user handbook for full details).
Plans are introduced by the timeswitch table i.e. dependent on the time of day, day
of the week and (optionally) on the date. Plans can also be introduced via the
667/HB/26568/000

handset or via user defined conditioning. The DUSC facility has the following
features:
(a)
Up to 16 plans, with 32 groups per plan. Up to 32 streams.
(b)
Timeswitch table with up to 64 entries.

Detector Loops being fed into the OMCU, which are then sent out from the OMCU to
the traffic controller. It also shows the ‘Green Confirms’ coming back from the traffic

4.2.10 Flow Facility
The Flow facility has 16 detectors, each provides flow data over a configured period
of time. Configuration data for this facility includes:- Flow Up Threshold, Flow Down
Threshold, Flow Smoothing Factor and Flow Count Period.
The Instation will send a Log Flow Request to the OMCU. It will request the OMCU
to start/stop accumulating smoothed flow data after a specified delay. The delay is
computed by the Instation so that the command will be executed by the OMCU at the
time of day specified by the user.
The OMCU will reply to the Log Flow Request with a message indicating that the Log
Flow Request has been received.
667/HB/26568/000
Page 38
Issue 15
3U Traffic Outstation Handbook
For each interval completed a report is generated and stored in the Operations Log.
When the final interval has been completed and report generation has been enabled,
a report is written to the Fault Log to indicate that Flow Logging has been completed
and is ready for uploading.
More accurate values of flow data can be obtained at 2 or 3 sites, using the N+1
Count data. The flow threshold would be for the complete carriageway rather than
individual lanes.
In addition to the collation of the flow data, the flow data can be monitored and
compared to the configured up/down thresholds. If the flow data meets the ‘up’ or
‘down’ threshold, the related OMCU Event can be activated/deactivated and the flow
alarm is raised/cleared.

Occupancy Count Period.
The Instation will send a Log Occupancy Request to the OMCU. It will request the
OMCU to start/stop accumulating smoothed occupancy data after a specified delay.
The delay is computed by the Instation so that the command will be executed by the
OMCU at the time of day specified by the user.

For each interval completed a report is generated and stored in the Operations Log.
When the final interval has been completed and report generation has been enabled,
a report is written to the Fault Log to indicate that Occupancy Logging has been

4.2.12 OMCU Events and Switch Override Facility
The maximum number of OMCU Events and Switch Overrides is 16. Each OMCU
Event and Switch Override is independent and more than 1 can be active
simultaneously.
667/HB/26568/000
Page 39
Issue 15
3U Traffic Outstation Handbook
Configuration data for the OMCU Events facility includes:- Debounce Active Delay
and Debounce Inactive Delay.
An OMCU Event has to be continuously active for the configured active debounce
time, before a report is written to the Fault Log, indicating the OMCU Event is active.
Conversely, an OMCU Event has to be continuously inactive for the configured
inactive debounce time, before a similar report is written to the Fault Log, indicating
the OMCU Event is inactive. The Instation then processes these events via a
decision tree and takes the appropriate configured response (Switch Override).
The RMS Instation can request a Switch Override at the OMCU, when the OMCU
Event becomes active. The OMCU will reply to the Switch Override Request with a
message indicating that the Switch Override Request has been received.
When the OMCU starts the Switch Override (start time is reached) and report
generation is enabled, a report will be written to the Fault Log to identify the start of
the Switch Override.
The Switch Override will remain active for a fixed period of time, or until cancelled
from the Instation.
A similar report will be generated at the end of the Switch Override, (end time is
reached, assuming that an indefinite override period has not been specified) if
enabled.

4.2.13 Vehicle Classifier Facility
The Vehicle Classification facility provides classification of vehicles by length into a
maximum of 14 user specified length categories. Vehicles that exceed the length in
the longest length category are assigned to the “Unassigned” length category.
Vehicles that are not able to be measured (e.g. transit one of the loops only) have
zero length and are assigned to the “Unmeasured” category. Each length category is
configurable to provide user names for the categories, e.g. “Car / Small Van”.
Vehicles may be logged on up to 8 loop pairs distributed across up to 4 sites, each
site containing up to 8 lanes. It is recommended that the facility use standard
SDE/SA loops of typically, 2m loop length and 3.5m loop separation. The ST4R loop
detector is also recommended.
It is important to note that differently sized loop pair configurations must be assigned
to different sites.
The vehicles may be individually logged in the Operations Log when they are
detected as VC events. The VC event identifies the vehicle type, length, speed,
headway and action taken (if any) on detecting the vehicle. Each value may be
optionally configured for inclusion / exclusion from the VC event.
VC event logging may be enabled / disabled for any given lane within a given site via
the configuration download.
667/HB/26568/000
Page 40
Issue 15
3U Traffic Outstation Handbook
The user is able to freely specify up to 32 detection conditions via special
conditioning e.g. vehicles of between 2m and 5.5m in length occurring at a given site
travelling in excess of 80kph. Of these 32 detection conditions, up to 16 may be
selected for statistic collection purposes.
NOTE : Non-vehicle classifier special conditioning mnemonics may be used in the
definition of the detection conditions, however they should not be mixed with the
vehicle classifier special conditioning mnemonics.
Vehicle detections may be collected over a user specified averaging period of
between 1 and 60 minutes to be summarised in the Operation Log as TD events by
average speed, average occupancy and average headway. The average speed,
headway and occupancy values may be recorded on a site or a lane basis or be
omitted entirely. The statistic categories increment during the averaging period to
reflect the occurrence of user defined detection conditions. These category counts
are presented in the Operations Log alongside the summary information in the TD
event described above. The statistic categories may be omitted from the TD event.
The data collection is synchronised to the minute boundary. The time stamp
associated with the TD event corresponds to the end of the averaging period.
TD event generation may be enabled / disabled via the configuration download.
When a vehicle detection satisfies a detection condition, a DC event may be
recorded in the Operations Log identifying the detection condition. It is possible for a
single vehicle detection to satisfy more than one detection condition (depending on
how the detection conditions have been defined) and hence there may be more than
one DC event associated with a single vehicle detection.
The DC, VC and TD events in the Operations Log may be selectively uploaded to the
RMS instation for analysis.
The occurrence of a user defined condition may be used to force the activation of
one or more OMU outputs (up to a maximum of 16 allocated across 2 output ports)
to trigger an action in an external device such as a traffic controller. A configurable
text message may also be presented to one or more message signs such as UVMS
or a SIESPACE sign. A sign may be connected to the 141 serial port or one of the
available RS485 serial ports on a 1 to 1 basis. The text message is displayed for a
configurable period and may be subsequently blanked by a blanking message
applicable to the sign or be replaced by a second text message. NOTE : If a second
text message is output to the sign, the message will remain on the sign until another
action causes the same sign to be addressed. Alternatively, the sign configuration
could perform a self blanking using a suitable inactivity timeout.
Confirmation checks are carried out to detect the absence / presence of an expected
input state arising from an output activation. The absence of an expected input state
for a configured period generates a fault in the Fault Log. The presence of the an
expected input state for a configured period clears the fault (if the fault is present).
The fault may be manually reset by the RMS instation operator.
NOTE : Confirmation checks are not performed on sending text messages to a sign.
Vehicle absence / presence faults are generated in the Fault Log if a vehicle is not
detected over a loop / detected over a loop for longer than the configured absence /
667/HB/26568/000

Issue 15
3U Traffic Outstation Handbook
presence time. Both fault types are automatically cleared by the OMU. Both fault
types may be manually reset by the RMS instation operator.
The Vehicle Classification facility also supports a loop pair fault algorithm. This
algorithm identifies a loop pair as faulty if one of the loops is activated on N
consecutive occasions with no activations on the other loop. The fault is cleared by
the OMU if there are M activations (not necessarily consecutive) of both loops. N and
M are configurable values.
The loop pair fault may be manually reset by the RMS instation operator.
There is a set of read only handset commands to allow the user to examine the
Vehicle Classifier configuration data items – see section 11.18.
The Vehicle Classification facility requires the use of an STCL supplied licence
code in order to be activated. The licence code is based on the OMU telephone
number and is downloaded as part of the Vehicle Classification configuration
data from an RMS instation.

4.2.14 Remote Automatic incident Detection (RAID)
With possession of the requisite licence the RAID facility can be enabled in the
OMCU. RAID, an acronym for Remote Automatic incident Detection, is a new
incident detection algorithm that has been developed as part of the EU 5th
Framework PRIME project (Prediction of congestion and incidents in Real time, for
intelligent Incident Management and Emergency traffic management).
A fully operational RMS resident RAID system has functionality split between the
outstation and instation. The outstation carries out low level loop detection and
algorithm resolution to arrive at a value for the Average Loop Occupancy Time Per
Vehicle (ALOTPV). ALOTPV is a measure of the average occupancy of a vehicle
detector loop during a configurable measurement period (typically around 30
seconds).
Calculated values for ALOTPV are compared with pre-configured thresholds to
detect occurrences of congestion and then alert the traffic operator via the instation.
A maximum of 16 inputs are supported, these can be raw detector inputs from each
loop or, as per DUSC, inputs that have been conditioned via a downloaded
conditioning rule. Conditioning can carry out boolean operations on the raw detector
inputs. The results of threshold comparison are then fed to the OMCU Event feature
which enables control over the point at which a threshold being exceeded is
reported. For example one traversal of a threshold may not be considered indicative
of a congestion condition but if it were exceeded consecutively for say 5 averaging
periods it would. The event functionality provides a mechanism to facilitate this.

3U Traffic Outstation Handbook
In addition a means of logging ALOTPV over a configurable period of time is
supported. This logged data can then be retrieved from the outstation and used by
the instation for traffic analysis and reporting.
The instation provides the means of setting thresholds and logging criteria for
ALOTPV and communicating them to the outstation via the normal configuration data
file. Additionally it is anticipated that different thresholds will be required for different
times of the day, days of the week or special occasions. To enable this requirement
a maximum of eight sets of thresholds is provided for each input.
A number of new handset commands have been incorporated in the firmware to
assist in field maintenance and fault diagnostics. These are covered in more detail in

DESCRIPTION AND REMARKS
Raid Threshold Set in current use.
RAID ALOTPV – current value of ALOTPV n
RAID ATGBV – current value of ATGBV n (future implementation)
RAID ALOTPV Threshold – threshold for ALOTPV[n][Threshold Set]
RAID ATGBV Threshold – threshold for ATGBV[n][Threshold Set]
(future implementation)
RAID ALOTPV High – Shows 16 ALOTPV detectors, 1 indicates that
the ALOTPV was above the high threshold during the last averaging
period.
RAID ATGBV Low – Shows 16 ATGBV detectors, 1 indicates that the
ATGBV was below the low threshold during the last averaging period.
(future implementation)
RAID Averaging Period – Time in seconds over which RAID
measurements are calculated.
RAID Enabled – check if RAID license enabled. 0 = disabled, 255 =
enabled
The RAID facility requires the use of an STCL supplied licence code in order to
be activated. The licence code is based on the OMU telephone number and is
downloaded as part of the RAID configuration data from an RMS instation.

4.3 GSM OMCU
The GSM OMCU is an extension to the Siemens RMS OMCU described in section
4.2 above. It provides an extremely cost effective means to monitor and control
equipment where standard PSTN connection is not available or where the line
installation costs are prohibitive.
See Sections 2.1 and 2.6.2 for further details of the GSM option.
4.3.1 Remote Monitoring
The GSM version provides all the facilities of a standard 3U OMCU and is capable of
monitoring a wide variety of traffic signal and pedestrian controllers. The unit is
configured from a RMS via a dial-up link to perform the monitoring and control
functions required.
When a fault or other defined event is detected, it is logged at the unit and a call is
made to the Instation to report the occurrence. If required, particular types of fault or
event can be configured as “non urgent” so that these are logged but not reported to
the Instation, unless a more urgent fault is detected or a call is made from the
Instation.
Integral n+1 count units allow simple detector equipment to be used to monitor traffic
flows, which are reported to the Instation automatically or on operator request.
Direct connection to a wide range of traffic controllers via their handset port allows
an operator at the Instation to interrogate the controller remotely and make changes
to the controller operation.
Variable Message Signs and access control equipment such as barriers may also be
controlled.
4.3.2 Bus Priority and Access Control
When used for Bus Priority and access control applications, the GSM OMCU is able
to connect up to 12 SIETAG readers using a suitable I/O board to provide logging,
priority and access control functions.
Vehicles to be given access / priority are fitted with an electronic tag that may be
programmed with, among other things, vehicle operator identification and individual
vehicle number. A loop is located in each access lane, which is used by a SIETAG
reader to interrogate tags as they pass over.
Data from the tags may be filtered by the GSM OMCU, which logs the information
and can be programmed to output access requests to barriers or other equipment
such as Traffic Controllers, via up to 16 isolated relay contacts. (These may be
expanded up to 48 by the addition of extra I/O boards.)
Several levels of filtering may be configured from the Instation and downloaded to
the GSM OMCU. Filtering options range from specific access or priority just for
uniquely identified vehicles through to all vehicles of a particular operator. Access /
priority may be restricted by time of day and individual or groups of vehicles may be
blacklisted.

Bus Processor and OMCU functions can be performed simultaneously, limited only
by the number of I/O boards that can be accommodated.

5. INSTALLATION
WARNING
THIS EQUIPMENT MAY ONLY BE INSTALLED BY SIEMENS TRAFFIC
CONTROLS OR BY TRAINED PERSONNEL.
AUTHORISED INSTALLER MUST ENSURE THAT INSTALLATION OF THIS
EQUIPMENT DOES NOT INTERFERE OR DEGRADE THE DESIGN
SPECIFICATION OF THE HOST EQUIPMENT IN ANY WAY WHATSOEVER.
ENSURE THAT THE UNIT IS NOT CONNECTED TO THE PSTN LINE DURING
INSTALLATION AND SWITCH OFF ALL MAINS TO CABINET PRIOR TO
STARTING.
THIS UNIT CONTAINS BATTERIES WHICH, UNDER FAULT CONDITIONS, MAY
LEAK HAZARDOUS SUBSTANCES.
CARE MUST BE TAKEN WHEN FITTING BATTERIES OR HANDLING THE UNIT.
FIT BATTERIES ONLY WITH SPECIFIED OR EQUIVALENT TYPE. BATTERIES
FITTED INCORRECTLY COULD CAUSE AN EXPLOSION.
THE UNIT IS ONLY COMPLETELY DISCONNECTED AND ISOLATED FROM THE
INCOMING MAINS SUPPLY WHEN THE MASTER SWITCH IN THE
CONTROLLER IS TURNED TO THE OFF POSITION. REMOVING THE MAINS
LEAD IS NOT SUFFICIENT.
ZX0 WIRES FROM THE PSU TO THE FIRST LMU I/O BOARD (NEAREST CPU)
The red and black wires that come from under the power supply cover,
through the ferrite are at mains potential when the unit is switched on. For
240V operation, these wire connect to pins ‘14’ and ‘11’ on the expansion
board connector ‘PL2’ (for full details of the connections see section 5.2.4 of
this handbook which starts on page 51.)
The mains supply must be completely removed from the unit prior to:
• Disconnecting these wires for any reason, e.g. replacing unit.
• Any ZX0 circuit setting adjustments as defined in section 5.2.4.
• Any operation that would leave these wires exposed.
If, for any reason, these wires are left exposed and unattended (e.g. change
out unit) they must be safely terminated with the unit unplugged from the
mains’ supply. The unit must not have mains applied to it until the wires are
connected or safely terminated, for example by removing additional wires so
that only the bullet connections, which provide protection against accidental
contact with mains potentials, remain.
During a unit change out, the Green Voltage Detector connections can be left
intact on cableform 667/1/26586/000 which connects to the controller (as
defined in section 5.6.5 which starts on page 65).

WARNING
ZX0 WIRES FROM THE UNIT TO THE FIRST LMU I/O BOARD (NEAREST CPU)
The red and black wires that come from under the power supply cover through
the ferrite are at mains potential when the unit is switched on.
The mains supply must be completely removed from the unit prior to:
• Disconnecting these wires for any reason, e.g. replacing the unit.
• Any ZX0 circuit setting adjustments as defined in this section.
• Any operation that would leave these wires exposed.
If, for any reason, these wires are left exposed and unattended (e.g. change out
unit) they must be safely terminated with the unit unplugged from the mains’
supply. The unit must not have mains applied to it until the wires are
connected or safely terminated, for example by removing additional wires so
that only the bullet connections, which provide protection against accidental
contact with mains potentials, remain.
The unit’s Power Supply operates from 85 to 265V AC, and therefore needs no
external set-up to operate from either 120 or 230V AC.
However the OMCU’s lamp monitor Zero Crossover circuit requires setting. This
setting is achieved by selecting the correct input connector socket on the High
Voltage cable form. The Basic Unit 667/1/28850/000 is supplied with one of the High
Voltage Cableforms 667/1/26586/800 fitted, with the selection for 230V already
made on that cableform.
If the OMCU cable 667/1/28852/000 is requested then high voltage cable
667/1/26586/000 is provided with 230V operation selected. If 120V setting is
required, change the setting as detailed, before applying mains. The relevant
connector socket positions for the 120V or 230V setting is described on the following
page.
Note that if OMCU lamp monitoring is not required, then the wires from the PSU can
be left unconnected since the female bullets have plastic covers that naturally
insulate them.

The total termination impedance (the ‘sum’ of both ends) for each channel should be
60Ω. For links up to 250m the I/O board can provide the total termination. If a longer
link is required, the far end of the link should be terminated with 120Ω and the I/O
board set to only provide a 120Ω termination.
The total termination impedance must be calculated, based on the terminal
impedance provided by all other equipment connected to the communication
channel. So in some circumstances, where termination is provided by that
equipment, the I/O board may need to be set to ‘not terminated’ (no resistors
selected).

5.4 HARDWARE INSTALLATION
5.4.1 General Installation
The unit assembly is a 3U extended unit, requiring 192mm of 3U Rack space. This
feature, together with the configurable cableforms, provides sufficient flexibility to
install the hardware in most controllers, in one of the three positions described
below. Also see Appendix B for details of part numbers.
(a)
The unit may occupy unused space, in a suitable rack with sufficient space,
which exists in a controller's cabinet. See bottom half of 667/GA/26577/000
drawing in Appendix B .
(b)
If no suitable rack space exists as in (a), the unit rack mounting facility can be
used (the M6 screws in rack angles) to allow the unit installation. See top half
of 667/GA/26577/000 drawing in Appendix B .
(c)
If all fails, then an alternative suitable method should be adopted, with the
collaboration of Poole Engineering using form 667/ST/17500/000 as defined in
section 5.3, or use an Additional Outercase. If the Additional Outercase
method is used, then additional installation work is required (see section 5.7
on page 73).
The OMCU comes as a Basic Unit containing one LMU I/O board and the 141 cable.
This is the basic OMCU for use with ST800/700 series controllers. For other
controllers an OMCU cable unit kit is required. The OMCU may require further
Expansion kits (containing one LMU I/O board and all its fixings), depending on the
size of the intersection. Before an OMCU can be installed, these expansion kits
require assembling to the Basic Unit. To assemble these expansion kits to the Basic
unit, use the methods and Items Lists on General Assembly drawing
667/GA/26580/000 in Appendix B .
For MOVA fit 667/1/28851/000 and if necessary, depending on the controller type, fit
667/1/28854/000 or 667/1/28855/000.
Prior to the development of a combined OMCU/MOVA unit, a MOVA unit with a
separate OMCU unit was normally supplied with the two units already built into a
new 3U rack. If sufficient space is not available in the controller cabinet for this rack,
then the units may be removed from the rack and each installed separately as
described above.
The following are important points to remember during assembly and installation
when the OMCU is fitted with LMU I/O boards:
• Ensure that the rear cables (High Voltage and Low Voltage), are connected to
their monitoring points and plugged into the unit, before installing the unit into
the Rack or Cabinet.
• Ensure that the Mains' feed from the PSU assembly to the High Voltage cable
form is connected for the correct voltage; see section 5.2.4, which starts on
page 51.
• Ensure that the voltage protection covers on the I/O board or boards are fitted
and securely fixed.

5.4.2 Radio Clock Installation
[This section only applies to Bus applications]
The optional Radio Clock is a separate unit that is mounted external to the OMCU
using a bracket supplied with the unit. It provides a time signal to the traffic outstation
received from the MSF Rugby transmitter. This is used to synchronise the internal
real time clock.
The system has good tolerance to interference and only requires valid reception for a
few minutes each day to maintain the accuracy of the clock. It is however a sensitive
radio receiver operating at 60Khz (for Rugby MSF transmissions) and certain
precautions are necessary.
• It should not be located near to radio transmitters.
• It should be kept as far away as practicable from a SIETAG reader or
vehicle detector loops. In some cases detector loops might have to be set
to operate on different channels as they can radiate at the same
frequency as the Rugby transmitter.
• It must be orientated correctly to point towards the Rugby transmitter. See
below and also see ‘RCS’ on page 185 for details on the use of the
handset for verifying radio reception.
Cabling to the Radio Clock should be separate from other intersection cables,
particularly detector loop feeders, to avoid electrical noise being injected into the
Radio Clock via its supply. A screened cable is recommended.
The Radio Clock is required to be connected to a digital input on a Bus / MOVA I/O
Board (defined during the configuration process) and to signal ground. The current
version of the radio clock derives power from its internal battery and no additional
power connection is required. Earlier versions (with 3-core connection cable) require
an external supply, which may be derived from the OMCU via the 13.8V bullet
connector at the rear of the OMCU. If the I/O cable 667/1/26585/010 is used then a
dedicated supply connection is provided.

5.5 CABLE AND WIRING
[This section applies to all applications]
It is not possible to adopt a standard cable routing, as mention in 5.1, but the
following guidelines should be adhered to:
(a)
(b)
Secure all cables to the controller frame or other suitable locations.
Cables should not obstruct the maintenance work on the controller, the unit
being installed, or any other equipment fitted within the cabinet.
5.6 INTERFACING
[This section applies to all applications]
This comprises the connection of the various types of circuits contained in the unit to
different equipment being monitored. For example:
OMCU Circuit
Traffic Controller Monitoring Point
Analogue Circuits
Current sensors for monitoring Aspect Current and
Voltage Monitoring Transformer for monitoring Lamp
Supply voltage.
Low Voltage Circuit
To monitor Phase Greens
Extra Low Voltage Circuit
Digital Signal Monitors e.g. Detector Inputs, Controller
Micro Switches, etc.
This is not an exhaustive list and other applications exist. The following sub-sections
detail the methods for the interfaces mentioned...

The current sensors must not be fitted to mains’ leads carrying
current unless they are plugged into their respective LMU I/O
boards to terminate them; otherwise they may produce a high voltage.
Warning
Each controller signal output, which is to be monitored, requires one current sensor
as described on the RMS Instation computer printout. Examples of output types to
be monitored are indicated in the following list. They all require one current sensor
unless otherwise stated:
(a)

(i)
Each switched sign phase
If regulatory signs are to be monitored then they need to be grouped together
Each "flashing amber signal group" phase requires one or two current
sensors, depending on monitoring requirements (this phase type is applicable
to export signal sequences only)
Each current sensor can monitor currents up to 4.25A RMS.
If the nominal load current (not including the red/ambers) of a particular controller
output exceeds approximately 4.0A RMS, then that output should be split and
treated as two separate outputs.
The maximum regulatory sign load is restricted to 7 signs (21 tubes) per input
(choke/ballast types only allowed).
The current sensors measure the current flowing in the wires that are passing
through their core. To maintain the correct relationship between the current flowing in
the conductor and the output from the sensor, the sensors must be connected the
correct way round (see following diagram).

Connect digital monitors cables (Unless
using ST800 enhanced serial link)
5.6.4
Digital Monitor points within the controller should be connected using the cableform
667/1/26585/000 as detailed on the Instation Computer Printout.
The connectors for these cableforms are on the underside of the board; i.e. on the
opposite side to the mains’ states connector. The silk-screening for their
identifications (PL3 and PL4) and arrows are located on the topside of the board,
near the edge.
These Inputs are not polarity conscious, but are voltage conscious. This means they
are connected one way for 24V logic working and the other way for 5V logic working.
Hence the method of selecting 24V or 5V working is by reversing the inputs to the
I/O Board.
For example, referring to the Extra Low Voltage Input 0, then for 24V working,
connect the lead from PL4 pin 1 to the +ve signal and PL4 pin 2 to the -ve signal. For
5V working, connect the lead from PL4 pin 2 to the +ve signal and PL4 pin 1 to the ve signal.
Most modern controller vehicle detectors will switch with an "on state" to their outputs
with a threshold below 1V. If this is the case, then set all these circuits for 5V
working. This has the advantage of using the inputs the same way round for all
inputs on an installation, and is the preferred method.
If this method is used, but occasional false detections or drop out occur (probably
caused by noise), then reverse all 24V detector monitors inputs at that installation.
The common lead(s) should be taken to the appropriate point within the controller.
These commons for the 24V working are typically the detector supply voltage itself;
i.e. +24V and the odd number pins are used. Whereas for logic signals working is
typically referenced to the Controllers +5V supply and the even number pins are
used.
This may not solve the problem in all
cases as noise at voltages higher than
common supply voltage may trigger the
‘reverse circuits’. (For example, when
monitoring 24V signals, if the signal
voltage goes above the common voltage
by between 1V to 3V the 5V monitor
circuit will be triggered.) If such problems
occur a diode (1N4007) may be inserted
between the common supply and the
OMCU inputs as shown.

There are two Extra Low Voltage cableforms to each I/O Board. They are made from
ribbon cable and therefore need to be spilt as required to suit the routing at the
installation. It is therefore recommended that care be taken during the configuration

process at the Instation, to ensure that detectors on a terminal block should not be
split over different ports.
Each cableform can cater for up to 8 inputs, and have the same colour coding, as
defined below. The input ports are allocated to LMU I/O Boards in the following
order. If Bus / MOVA I/O boards are also fitted, then the OMCU application can also
read the inputs on those boards, see section 5.6.5 overleaf.
1st LMU I/O Board Ports 0 (PL4) & 1 (PL3) Inputs 1 to 16
2nd LMU I/O Board Ports 2 (PL4) & 3 (PL3) Inputs 17 to 32
3rd LMU I/O Board Ports 4 (PL4) & 5 (PL3) Inputs 33 to 48

The connectors for these cableforms are on the underside of the board; i.e. on the
opposite side to the mains’ states connector. The silk-screening for their
identifications (PL3 and PL4) and arrows are located on the topside of the board,
near the edge.

a 2 lane approach, "D" would not be required) they must be left unconnected. Where
U/D operation is not required, the "U" input must be left unconnected.
THEY MUST NOT BE USED FOR ORDINARY DETECTOR OR DIGITAL INPUTS.
However, inputs 5 to 7 on a ‘count’ port can be used as normal OMCU digital inputs.

The Bus / MOVA I/O Board has different digital input and output connectors than the
LMU I/O board described in section 5.6.4. If a Bus / MOVA I/O board is fitted to an
OMCU to perform bus processor functions, then this section details the digital I/O
connections on that I/O board. However, if the I/O board is used for MOVA, see
sections 9.2, 9.3 and 9.4 which start on page 103
The table on the following page shows the functions associated with the digital I/O
connectors on the I/O board. It shows the Buffered Input’s and Isolated Output’s
numbering allocation for the first and second I/O boards, although the actual I/O line
numbers used by the unit will depend on the position of the boards in the stack.
There are different cableforms that may be connected to PL1 and PL2 connectors of
the I/O board. These are to cover differing connection requirements. For the relevant
cableforms and their wire colours and terminal block allocations see drawing
667/GA/26585/003, 667/GA/26585/004 and 667/GA/26585/010 at the back of this

The OMCU application (in PB680 and PB681 issue 10 and later) can also read the digital inputs on any Bus / MOVA I/O boards
that are fitted. The following diagram and table summarise where the OMCU’s 64 detector inputs are located when various
combinations of I/O boards are fitted. For example, in addition to the 32 inputs on two LMU I/O boards, the OMCU can also monitor
all 32 MOVA detectors on a MOVA I/O board (PL1 1 to 24 and PL2 1 to 8):

Note that the RS485 serial port numbers are determined by the board address (set
as described in section 5.2.1). Thus for example, the second I/O board is always
allocated RS485 serial port numbers 4 to 7, even if the first I/O board is a LMU I/O
type.
For the relevant cableform and their wire colours and terminal block allocations see
drawing 667/GA/26585/004 at the back of this handbook.
Normally, each SIETAG unit in a Bus Processor will be connected to one of these
RS485 serial ports. An overview of the SIETAG bus processor functions is given in
section 4.2.5. The wiring is as follows:
‘A’ connects to SIETAG backplane pin 21
‘B’ connects to SIETAG backplane pin 15
667/HB/26568/000
Page 69
Issue 15
3U Traffic Outstation Handbook
NB: Ensure that the Sietag backplane is fitted with a link connecting the through-hole
immediately above silk screen number "14" to the through-hole above silk screen
number "21".
The line termination resistors on the BUS/MOVA I/O board should be set to 120 Ω as
described in section 5.2.5.
The serial port to which each reader is connected must correspond with the data
configured for the OMCU on RMS screen 500. The SOP command can be used to
check that the BUS/MOVA I/O boards are being correctly detected by the OMCU,
see page 182.
The OMCU RS485 serial port configuration must match the Sietag reader in order to
receive data i.e. 9600baud, parity disabled, 1 stop bit and 8 data bits. The serial
ports are configured on RMS screen 510 or via the POC command in section 11.10.
The DBM command (see section 11.9) can be used to display received characters
on the RS485 serial ports. The SIETAG reader outputs an “LI” text string repeatedly
in the idle state. While a vehicle tag is being detected, the reader outputs the tag
number in HEX, e.g. “LM 123456789ABCDEF”

5.6.8
(a) Routing of cables
Signals for the following groups may be bunched together but must not be grouped
to other cables or other cabinet signals to reduce the occurrence of extraneous
signals upsetting the monitoring unit.
Group 1 - Digital Monitoring Signals.
Group 2 - Analogue Monitoring Signals.
Group 3 - Green Volts Detect Signals.
(b) Earth Continuity
The EARTH CONTINUITY RESISTANCE must not exceed 0.5 Ω on exposed metal
parts of the unit when measured with reference to the EARTHING TERMINATION
POINT of the cabinet.

3U Traffic Outstation Handbook
(c) Check On Integrity of Neutral Connections
With the controller switched on and cycling and a multi-meter set to measure AC
volts - measure the voltage between each green feed and neutral, when the green is
off. The voltage should be less than 5V RMS to meet IEE Regulations BS7671, if it is
not then the neutral connection between the controller and the signal head(s) being
tested may be faulty. Inspect all neutral runs that appear faulty, to ensure they are
not loose or corroded.

Identify all connectors/cable forms
Connect all connectors to the unit
The label sleeve attached to all Monitoring Cable Form Assemblies, with the specific
purpose of identifying the I/O Board and connector to which the cable form assembly
is connected, should be marked with a permanent marker pen to identify its
connector ID and board location, as follows:
For example:
‘PL1/1’ = Plug 1 - Board 1
‘PL4/3’ = Plug 4 - Board 3
All the cables should be connected to the unit at this point.

Connect 141 cable to controller handset port
(req’d for MOVA if using ST800 link)
5.6.10
The OMCU communicates with a controller using ribbon cable 667/1/26579/XXX.
The variant depends on the type of controller being monitored. Section 7.5 on page
87 lists the different variants of this cable.
Insert this cable into plug PL4 (SIL 18 way) on the processor board (see drawing
667/GA/26580/000 in Appendix B ), and the other end (25 way 'D' Type), into the
appropriate 'Handset Socket' of the controller.
Note: This cable is required if MOVA is to use the enhanced serial link to an ST800
even if the OMCU application is not required, see section 4.2.6 on page 32.

IMPORTANT
The wires in the mains’ lead are coloured as follows:
BROWN – LIVE
BLUE – NEUTRAL
GREEN / YELLOW – EARTH
Mains’ power is supplied to the unit through a 6A rated 3-core flex.
Normally the unit is powered from an auxiliary mains supply provided within the
controller. In controllers without this facility or if this is not convenient, a suitable
alternative mains supply must be provided, being careful not to compromise the
safety of the controller (Refer to Poole Engineering if in doubt).
Do not connect the mains supply input of the unit to the lamp supply of the controller,
as this will cause the unit to operate incorrectly.
Mains fused: The recommended rating of this external fuse is up to 5A anti-surge.

To connect the Unit Support Battery, the fuse (Part Number 518/4/90285/008
supplied separately), is inserted in the Battery Fuse Holder on the front panel. If the
unit is to be left not powered after installation, this fuse should be removed and
stored in a safe place, ready for insertion during commissioning.
Remember that MOVA and Bus Processor units do not normally require a ‘Unit
Support Battery’; consult the Works Specification for requirement.

Issue 15
3U Traffic Outstation Handbook
When installing the Siemens OMU the detector monitoring inputs require access to
the same 24VDC supply as is used to reference the detector inputs. At present this
is not directly available.
To make the 24VDC supply available to the Siemens OMU the supply should be
taken from the back of the TRX backplane. Soldering a wire to the connector pin
“+24VDC” on the TRX backplane should make the connection. This wire is then
connected to the wires from the OMU I/O connector, odd numbered pins (1, 3, etc). It
is suggested that the first wire (brown) is used and all other odd numbered pins
connected to this brown wire using a connector block. The detectors being monitored
using this method should not exceed a current loading of 250mA under normal
operating conditions.
Any detectors monitors that are used to monitor loop detectors wired using TRX
detector backplanes can still access the relevant detector input using a screw
terminal on the IOT PCB.

Therefore if a loop detector is configured as input 1 it can be monitored on the

5.7 INSTALLATION OF THE UNIT IN ADDITIONAL OUTERCASE
When considering installation of a unit it is not always possible to mount it in the
same cabinet as the controller. In these circumstances an additional outercase will
be needed which can be installed up to 8 metres from the controller.

6. OMCU COMMISSIONING
WARNING
THIS EQUIPMENT MAY ONLY BE COMMISSIONED BY SIEMENS TRAFFIC
CONTROLS OR BY TRAINED PERSONNEL.
ENSURE THAT THE UNIT IS NOT CONNECTED TO THE PSTN LINE JACK UNIT
AT THE COMMENCEMENT OF COMMISSIONING TESTS.
ZX0 WIRES FROM THE PSU TO THE FIRST LMU I/O BOARD (NEAREST CPU).
The red and black wires, which come from under the power supply cover
through the ferrite, are at mains potential when the unit is switched on. For
240V operation, these wire connect to pins ‘14’ and ‘11’ on the expansion
board connector ‘PL2’ (for full details of the connections see section 5.2.4 of
this handbook which starts on page 51.)
The mains supply must be completely removed from the unit prior to:
• Disconnecting these wires for any reason, e.g. replacing unit.
• Any ZX0 circuit setting adjustments as defined in section 5.2.4.
• Any operation that would leave these wires exposed.
If, for any reason, these wires are left exposed and unattended (e.g. change
out unit) they must be safely terminated with the unit unplugged from the
mains’ supply. The unit must not have mains applied to it until the wires are
connected or safely terminated, for example by removing additional wires so
that only the bullet connections, which provide protection against accidental
contact with mains potentials, remain.
During a unit change out, the Green Voltage Detector connections can be left
intact on cableform 667/1/26586/000 which connects to the controller (as
defined in section 5.6.3 which starts on page 61).

6.1 INTRODUCTION
The checklist on the following pages should be used to commission the OMCU and
Bus Processor applications if they are required.
The checklist should be followed in sequence unless a particular step is not required.
Refer to the ‘OMCU’, ‘Car Park [Count OMCU]’ and the ‘Bus [Processor]’ columns to
determine whether the step applies to the type of unit being commissioned. If the unit
is to perform both OMCU and Bus Processor facilities for example, then all activities
in both the ‘OMCU’ and ‘BUS’ columns should be undertaken.
Section 9 which starts on page 101 describes MOVA and includes its commissioning
steps. If the OMCU and MOVA applications are required within the same unit, then
the OMCU commissioning checklist must be followed and then the MOVA
commissioning checklist.
In most cases, the unit has all of its timing and configuration data downloaded from
the central office. On site set-up can be performed where required for bus
processing functions, see section 11.10.

7.3 FAULT FINDING
The unit is a modular design, which simplifies faultfinding to a board or assembly
level. Section 8 which starts on page 89 provides guidelines to faultfinding and
Repair to modular level. The status LED indicators on the processor board provide a
visual identification of the fault condition existing on the unit.
The OMCU software has a diagnostic routine, which when accessed by the handset,
can identify many other types of fault conditions. See section 11 for detailed handset
command codes and replies, along with their associated fault indications.
Note that the handheld handsets commonly used to interrogate traffic controllers and
other traffic equipment (including OMCUs) cannot be used to interrogate the MOVA
application since it requires menu driven application running on a PC. See section 9
for more information about the MOVA unit.

The slow flash rate is approximately one second on / one second off, whereas
the fast flash rate is much faster (several flashes per second).
†
When both the OMCU and MOVA applications are running on the same unit,
then the run LED will flash at the fast rate when either the OMCU has
detected a fault or the MOVA application is not on control.
If the software run LED is off, then this indicates that the board has lost power, e.g.
mains power has been lost and the battery is now flat, or there is a major board fault
that prevents the software running or the LED is faulty.
If an OMCU unit is not operating normally, i.e. the LED is flashing quickly, then it:
(a) has urgent faults present which have not yet been reported to the Instation
(the OMCU will be either dialling the Instation or in PSTN retry),
(b) is not monitoring, i.e. unconfigured, monitoring turned off, config data invalid,
config being downloaded, or
(c) has detected a OMCU ‘hard’ error condition, e.g. repeated failure of internal
software check
If a MOVA unit’s LED is flashing quickly then:
(a) MOVA is disabled or has been switched off control ‡,
(b) the MOVA unit has confirmed one or more faulty detectors (the ‘fault’ will not
be cleared until the error log is manually cleared), or
(c) the MOVA software has failed internally
‡
Note: After any power break, the MOVA unit will remain off control until the
controller has performed one complete cycle in its fallback mode. This is known
as the MOVA warm-up cycle.
7.4 ROUTINE MAINTENANCE
Units only require annual maintenance, which can be performed at the same time as
the inspection of associated controller or other equipment. On these visits, trained
personnel must switch off the mains power to the controller and the unit.
667/HB/26568/000
Page 85
Issue 15
3U Traffic Outstation Handbook
7.4.1 Annual Maintenance
For a unit fitted with battery support, switch the mains power off and check the unit is
supported by the battery for a minimum of 10 minutes. Do this by inspecting the RUN
LED and waiting until the power failure has been reported to the Instation. This tests
the condition of the Unit Support battery, and if the unit loses support within 10
minutes, the battery must be replaced. After the 10 minutes is up, remove the battery
fuse, which will power down the unit.
For any type of unit, carry out all the following procedures:
(a)
General inspections of the unit in situ for any contamination, overheating of
components, corrosion or battery leakage. Rectify where necessary.
(b)
Check the tightness of all interface cables and re-tighten where necessary.
(c)
Check the condition of the interface cables; that there is no chafing of the
insulation and that the general condition of the insulation is good. Replace any
damaged or worn cables.
(d)
Check the mechanical tightness of the main securing screws of unit and retighten where necessary.
(e)
Restore mains power to the controller and the unit. Check the controller and
other associated equipment is operating correctly. Then check the unit has
retained its configuration by observing the RUN LED returns to its normal
operating state, i.e. on steady or flashing slowly. In the case of an OMCU, this
will be after the power restoration has been reported to the Instation; or in the
case of a MOVA unit, once the controller has performed one complete cycle.
If the RUN LED continues flashing quickly then see section 7.3.4 and use the
handset port to examine the unit. This check only tests the RAM memory
support battery has not failed. It does not check its capacity and ability to
support the RAM during long power cuts.
(f)
Force the unit to call the central office and prove communications to the
operator. This can be achieved using the OMCU handset command CAL=1.
Note: Routine replacement of fuses is NOT considered necessary.
This completes the annual maintenance of the unit.
7.4.2 5-Yearly Maintenance
It is recommended that every five years, in addition to the annual maintenance
routine described above, rechargeable batteries be replaced. These are the optional
Unit Support battery and the RAM backup battery. See Section 7.6.3 for part
numbers.

8. FAULT FINDING AND REPAIR
8.1 INTRODUCTION
The following section comprises of battery, telephone connection information and
warnings, together with quick reference tables, to provide a guide to aid fault tracing
on the unit for first line maintenance purposes:
Table 8.4.1 : PSTN Communication Failures
Table 8.4.2 : GSM Communication Failures
Table 8.4.3 : MODEM COMPATIBILITY
Table 8.5 : EQUIPMENT FAILURES
Table 8.6 : POWER FAILURES
Section 11 provides a description of the codes that can be used in fault finding.
These codes are often referred to in tables 8.4 to 8.6 as HANDSET CODE.
8.2 BATTERY FAILURES
If one of the batteries has failed, it must be replaced with the specified battery or
equivalent (see section 7.6.3 on page 88). Exercise great care when handling old
batteries, which may be leaking, and during replacement of new ones, to ensure no
damage occurs to either.
WARNING
OLD BATTERIES MUST BE DISPOSED OF IN ACCORDANCE WITH THE
‘CONTROL OF SUBSTANCES HAZARDOUS TO HEALTH REGULATIONS 1988’.
SPENT BATTERIES MUST BE DISPOSED THROUGH AN APPROVED
HAZARDOUS WASTE DISPOSAL CONTRACTOR.
DO NOT PUNCTURE BATTERIES.
DO NOT DISPOSE OF BATTERIES IN ANY FIRE.
DO NOT ATTEMPT TO RECHARGE FAILED BATTERIES.
8.3 TELECOMMUNICATIONS APPROVAL WARNING
The PSTN Modem is approved for connection to the Public Switched Telephone
Network. This approval may be invalidated if any authority other than the original
manufacturer repairs the equipment.

Action
(a) Unit will not
answer Instation calls
PSTN line out of order
or disconnected
Check the line by disconnecting the unit from the line socket and inserting a
telephone handset. Try a voice call to and from the service depot. If line is OK,
the modem is powered and its connections are OK, replace modem.
Telephone cable
disconnected
Check the PSTN connections to the modem and the Line connection socket. If
modem is powered, and connections OK, replace the modem.
Modem failed
Check if the modem’s ‘‘ON” LED is lit, if yes replace modem. If no check that
the modem is switched on and voltage on the modem power cable is present
(see section 5.2.2 on page 50). If no voltage present, replace I/O board
providing the power. Note that a MOVA unit which is sharing the telephone line
with an OMCU will normally switch off the power to its modem, leaving the
OMCU to answer any calls from the RMS Instation (see section 9.4 on page
108).
NB: If the unit comm’s LED is repeatedly flashing, the unit is attempting (but
failing) to initialise the modem. Replace modem and/or check compatibility.
Unit out of service
Check that the statuses of the LEDs on the Processor board are correct (see
section 7.3 which starts on page 83). If not, power down and power up the unit.
If fault persists, replace the processor board.

9. MOVA
9.1 MOVA Introduction
IMPORTANT: BEFORE LOADING ANY CONFIGURATION DATA, REFER TO SECTION 9.6.7 ON PAGE 120.
The following is an extract from the introduction of AG10.
MOVA stands for Microprocessor Optimised Vehicle Actuation, a new strategy for
control of traffic light signals at isolated junctions - junctions uncoordinated with any
neighbouring signals. MOVA is designed to cater for the full range of traffic
conditions from very low flows through to a junction that is overloaded. For the
major part of the range, before congestion occurs, MOVA operates in a delay
minimising mode; if any approach becomes overloaded, the system switches to a
capacity maximising procedure.
The MOVA system requires vehicle detection by inductive loop or equivalent
detectors that provide both vehicle counts and presence information. Each traffic
lane approaching the junction has one or more detectors.
This 3U Traffic Outstation Handbook covers the installation, maintenance and
commissioning steps for the Siemens MOVA unit.
Also refer to the Highways Agency Installation Guide for MOVA (MCH 1542) and the
TRL booklets AG10, AG11 and AG12. These documents complement this handbook
by covering the design of MOVA intersections, such as determining the location of
the vehicle loops and the construction of the MOVA site data, as well as
commissioning the completed MOVA intersection.
The Siemens MOVA unit combines the TRL MOVA software with the Siemens 3U
traffic outstation hardware as used by the Siemens RMS OMCU.
Since the OMCU and MOVA share the common hardware platform, the installation
and maintenance of a Siemens MOVA unit is very similar to the installation and
maintenance of the OMCU. Therefore…
See section 5 for the installation and section 7 for maintenance details.
However, commissioning a MOVA unit is very different from commissioning an
OMCU or Bus Processor and thus this is covered later in this section.
Prior to issue 10, only the MOVA application is present in the PB681 firmware
PROM. From PB681 issue 10 onwards, the MOVA and OMCU applications are both
available within the same ‘3U Traffic Outstation’ unit. See overleaf…

The Original Siemens MOVA unit
Prior to issue 10, the OMCU
application was not available
in the PB681 MOVA firmware
PROM. Therefore, if the
traffic controller was required
to be monitored by a
Siemens OMCU, a separate
OMCU unit needed to be
installed.

These two 3U units were
normally supplied ‘ready built’
in a single 19” 3U rack as
shown right, and could share
the same telephone line, see
section 9.4 on page 108.
Back
Note that MOVA units installed this way can be upgraded with the new firmware, i.e.
issue 10 or later. The new firmware will automatically detect and function as either a
separate MOVA unit phone line sharing with a separate OMCU or as a new
‘integrated’ OMCU/MOVA unit (see section 9.6.3 on page 116 for more information).

This unit is fitted with a single processor
board fitted with PB681 rather than PB680
firmware, one or two LMU I/O boards to
provide the OMCU with its detector and
mains’ state inputs, and one Bus / MOVA
I/O board to provide MOVA detectors,
force and confirm bits.

9.2 MOVA Interfaces
Since the MOVA unit uses the same hardware platform as the OMCU, the interfaces
are similar to those of the OMCU and thus most are covered by section 5.6 which
starts on page 57.
There are two main exceptions:
(i) Access to the MOVA application through the handset port.
Access to the MOVA application is via a PC running suitable software connected
to the 25 way D-Type port on the front of the processor board, see section 9.6.1
on page 114. The same software must also be used to communicate with the
MOVA unit across the telephone line, see section 9.7 on page 128.
The MOVA application will not communicate with the small portable handsets
commonly used to interrogate other traffic equipment as it uses full screen
displays rather than simple handset commands.
On an Integrated OMCU and MOVA unit, this PC application can be used to
communicate locally with the OMCU application as well as the MOVA application.
(ii) The digital inputs and outputs used by MOVA are pre-allocated since the MOVA
site data is hardware platform independent. The MOVA application will
automatically use the 48 inputs and 16 outputs of the first BUS / MOVA I/O board
that is fitted as follows:
a) Detector inputs (1 to 32)
b) Confirm inputs (G1 to G10) plus the Controller Ready Bit (CR)
c) Force bit outputs (F1 to F13) plus the Take Over Bit (TO), but note that
MOVA can currently only control up to 8 stages (F1 to F8)
d) The phone line sharing handshaking signals to a separate OMCU (DM &
MF)
e) The ‘SP - Sync Pulse’ output which is only used during development

The use of each detector input, each confirm bit input and each force bit output and
their terminal positions should be recorded on a MOVA Installation Sheet. An
example of a MOVA Installation Sheet is given on pages 228 and 229.
667/HB/26568/000
Page 103
Issue 15
3U Traffic Outstation Handbook
Also note that PB681 issue 10 can use the enhanced 141 serial link to an ST800
through which it obtains all of its detectors and confirms from, and passes its force
bits to, the controller. See section 4.2.6 on page 32 and section 9.6.4 on page 117.
9.2.1 Detector Inputs and Push-Buttons
The detector inputs (1-32) are normally connected in parallel to the controller at the
controller’s terminal blocks.
Ensure that the detector inputs have been configured in the correct
sense in the MOVA site data. For example, on a Siemens T400 or
ST800 controller, the detector inputs are normally open circuit, closing when a
vehicle is detected.
Important
Note: On an Integrated OMCU and MOVA unit, the OMCU can monitor the MOVA
vehicle detector inputs on the MOVA I/O board. Therefore these detectors do not
need to be wired into the OMCU’s LMU I/O board(s) as well as the MOVA I/O board.
See section 5.6.5 which starts on page 65.
It is recommended that Push button inputs be configured as follows…
The controller should be configured to provide an output for each pedestrian phase,
which is then connected to the configured MOVA pedestrian detector input, rather
than connecting the MOVA unit directly to the push-button input(s).
This output should be activated when the controller has a demand registered for that
phase and thus are sometimes referred to as a ‘wait confirms’. But note that they
must be configured in the same sense as the detectors (e.g. normally open, closing
when a demand has been latched) which may be in the opposite sense to the stageand phase-confirm outputs.
9.2.2 Confirms and Controller Ready Inputs
The stage- and phase-confirm outputs from the controller should be configured as
held closed, opening when the stage/phase is active. The Controller Ready Bit
should be closed when the controller is ready.
Therefore, being physically normally open contacts, if the controller fails, then the
MOVA unit will see the controller ready bit disappear and multiple stage confirms,
and thus it will release control of the junction.
Unlike earlier versions of the MOVA software, version M4.0 does not normally
require separate phase confirms for phases which overlap stages, i.e. for phases
which appear in more than one stage. Thus, since MOVA can only control 8 stages,
10 confirm inputs should be adequate - one per stage plus two spare.
9.2.3 Force Bits and Take Over Outputs
When the MOVA unit is on control, it closes the ‘Take Over’ relay output and closes
the required stage force bit relay output.
667/HB/26568/000
Page 104
Issue 15
3U Traffic Outstation Handbook
9.2.4 Other I/O Signals
The ‘SP - Sync Pulse’ output is only used during development and should be left
unconnected.
The ‘MF- MOVA Fault’ and ‘DM - Disable Modem’ signals are used by the telephone
line sharing option described on page 108.
If this facility is not required, then prior to PB681 issue 10 firmware, the ‘DM’ input
must be connected to 0V and the ‘MF’ output left unconnected. On issue 10 and
later firmwares, this facility can be disabled using the PLS handset command
instead, see section 9.6.3 on page 116.
9.2.5 I/O Allocation
The standard cableform connects into these connectors and provides flying leads for
each pin. Since there are two connectors on each BUS / MOVA I/O board, PL1 and
PL2, then each board requires two identical cables. It is therefore recommended that
the cableforms be clearly identified before installation commences.
The wire colours used are described on the following page.
If more inputs are required, then a second BUS / MOVA I/O board can be fitted, also
shown on the following page. This increases the number of detector inputs by 32 and
the number of confirm-inputs by 16. However at the time of writing, the current
version of the MOVA firmware (M4.0) will only make use of confirm bits 11 to 16 on
the second board and none of the detector inputs.
An alternative cableform is available which simplifies connecting the MOVA unit up to
a Siemens T400 or ST800 traffic controller and this is described on page 107.

9.3 Connection To A Siemens T400 or ST800
To simplify connecting the MOVA unit to a Siemens Type 400 or Type 800 traffic
controller, an alternative cableform is available.
Note that no I/O cables will be required if MOVA is to use the enhanced serial link to
an ST800, see section 9.6.4 on page 117.
This cableform connects the first BUS / MOVA I/O Board’s connectors PL1 and PL2
directly to the controller’s UTC Expansion I/O Board’s four connectors PLB, PLC,
PLD and PLE. This cable also commons the 24V and 0V connections and thus only
requires two wires to be connected to the controller’s 24V and 0V supplies.
It cannot however replace the detector cables (or the phone line sharing signals) and
these still have to be connected during installation. Note that the colours of these
wires are the same as the colours used in the standard cableform that is detailed on
the previous page.

9.4 Telephone Line Sharing Connections
When a separate Siemens OMCU unit and Siemens MOVA unit share the same
telephone line, the two units ‘communicate’ with each other using two I/O lines. For
details of how to communicate remotely to telephone line sharing units, see section
9.7.2 on page 129.
The ‘MOVA Fault’ (MF) I/O line is an output from the MOVA unit to any detector input
on the OMCU. It is used primarily to inform the OMCU when the MOVA unit has
detected a fault, with the OMCU configured to report this event to the RMS Instation.
The ‘Disable Modem’ (DM) I/O line connects the first digital output of the OMCU to
an input on the MOVA unit. It is used primarily to request that the MOVA unit
switches off its modem so that the OMCU can have complete control of the
telephone line until the OMCU is instructed otherwise by the Instation. Note:Open
circuit disables MOVA’s modem so if telephone line sharing is not required, connect
DM direct to 0V.
The following diagram shows how these signals are connected between the MOVA
unit and the OMCU. Note that the I/O connections on the OMCU side are described
in more detail in section 5.6.1 (page 57) and section 5.6.4 (which starts on page 63).

If problems are experienced with the telephone line sharing system, the following
should help diagnose the cause of the problem:
• Check that the OMCU has been installed, commissioned and configured
correctly. The telephone line sharing system between the MOVA unit and the
OMCU will not function if the OMCU does not contain the necessary special
conditioning.
• Check that wires between the MOVA unit and the OMCU are as shown on the
previous page.
• Check the following diagrams show the expected states of these signals.
Normally, both signals will be open circuit, therefore the OMCU handset
command DIP should show the ‘MOVA Fault’ signal as a ‘0’ (‘No Fault’) and the
SOB handset command should have bit 0, the ‘Disable Modem’ signal, set to ‘0’
(‘MOVA Modem Disabled’).
The first diagram shows the MOVA unit passing a fault (or any other ‘Phone Home’
request - see section 9.7.4 on page 132) to the OMCU and the OMCU
acknowledging the fault after confirming the presence of the MOVA fault signal for a
few seconds. All timings are approximate.
n
Disable Modem (SOB): b
n
MOVA Fault (DIP): b
½ sec.
b = Open Circuit
n = Closed Circuit
3 seconds
To check this sequence, first check that both signals are in their normally open circuit
state, i.e. DIP and SOB both show ‘0’.
• Set the MOVA ‘phone home’ flag to ‘99’ (see section 9.7.4 on page 132).
• Use DIP to check the ‘MOVA Fault’ input to the OMCU changes from ‘0’ to ‘1’.
• Check that approximately three seconds later it returns to zero.
• Set the MOVA ‘phone home’ flag to ‘99’ again.
• Use SOB to check that approximately three seconds later, the ‘Disable Modem’
output is pulsed, i.e. changes from ‘0’ to ‘1’ and then back to ‘0’.
Note that if the OMCU is not configured correctly, or does not ‘see’ the ‘MOVA Fault’
signal, or the MOVA unit does not ‘see’ the ‘Disable Modem’ signal from the OMCU,
then the MOVA unit will leave its MOVA Fault output active. The phone home flag
will remain set to ‘99’ until it ‘sees’ its ‘Disable Modem’ input go active.
The second shows the OMCU releasing the ‘Disable Modem’ signal when the
‘Enable MOVA’ option is selected at the RMS Instation. When the subsequent call to
the MOVA unit is complete, the MOVA unit pulses its ‘MOVA Fault’ signal to ask the
OMCU to re-instate the ‘Disable Modem’ signal. Note that if the MOVA unit does not
pulse the MOVA fault signal, e.g. because no call was made to the MOVA unit, then
the OMCU will re-instate the ‘Disable Modem’ signal after 5 minutes (not shown).

9.5 MOVA Commissioning Checklist
The following checklist should be used to commission a Siemens MOVA unit. The
steps are expanded upon in section 9.6, which starts on page 113.
Note that where a separate OMCU unit and MOVA unit are both being installed
together into a controller and the two units are to share the same telephone line,
then the OMCU should be commissioned and configured first, before the MOVA unit
is commissioned, see section 6.
If an Integrated OMCU and MOVA unit is being installed, it is recommended that the
OMCU application be commissioned before the MOVA application. The checklist
should be followed in sequence:
Step Section
Action to be Performed
1)
5
Check that the MOVA unit has been installed correctly.
2)
6
Check that the OMCU has been commissioned correctly (when
MOVA is installed along side a separate 3U OMCU or where an
integrated OMCU and MOVA unit is being installed).
3)
5.2.8
Ensure the RAM backup battery is switched on.
4)
9.6.7
If using issue 10 or later firmware, all the cables can be connected
since the unit can now be re-initialised after the correct site data has
been loaded to ensure a ‘clean start’.
Warning for units running firmware prior to PB681 issue 10
Disconnect the MOVA I/O cables from the back of the unit’s I/O
Board. Always disconnect the I/O cables prior to initialising the unit
and reconnect them after the correct site data has been loaded.
Do not run the unit with I/O cables connected while the default site
data is still present prior to loading the new site data.
5)
-
Switch on the MOVA unit’s mains supply.
6)
7.3.4
Check that the RUN LED (LP3) is flashing. Note that MOVA will flash
this LED at the fast rate since the unit is not ‘On Control’.
7)
9.6.1
Connect the PC to the MOVA unit’s local port (the 25 way D-type
connector on the front of the processor board) and start the MOVA
communications application.
8)
9.6.2
Initialise MOVA by entering the handset command INI=2. If the
OMCU application is not required, enter INI=3 to completely reinitialise the whole unit.
[Prior to issue 10 – set the ‘Phone Home’ flag to 77]
9)
9.6.3
Ensure the unit has correctly determined whether the Phone Line
Sharing facility to a separate OMCU is required (‘PLS:1’ if enabled
and ‘PLS:0’ if disabled). If not, investigate the reason and correct.
667/HB/26568/000
Page 110
Issue 15
3U Traffic Outstation Handbook
Step Section
10)
9.6.4
Action to be Performed
If MOVA is to use a Bus / MOVA I/O Board, check that the SOP
handset command shows the correct type of I/O boards have been
detected and that MOVA is using one of them, see page 182.
If MOVA is to use the enhanced serial link to an ST800 but the
OMCU has not been configured, enable the facility manually using
‘MIO=2’ and check that the enhanced serial link is active, i.e.
‘EEL:3’.
11)
9.6.5
Enter the correct MOVA licence number, e.g. ‘LIC=1234 5678’.
12)
9.6.6
Set the time and date in the MOVA unit.
13)
9.6.7
Download the site data into the MOVA unit from the PC and then
clear the MOVA working data as instructed on the screen (only
available from PB681 issue 10 onwards).
14)
9.6.8
Use the commissioning screen to check for following.
a) MOVA is currently not enabled (MOVA enabled = 0)
b) The Controller is ready* (CRB = 1)
c) The Confirm bits are all set to ‘1’, except for the current stage
which should be set to ‘0’.
Watch the controller perform at least one complete cycle to check
that each stage and phase confirm bit is being activated correctly by
the controller.
* It may be necessary to press the 'Normal' button on the controller's
manual panel before it will activate the 'Controller Ready Bit'.
15)
9.6.8
Also use the commissioning screen to check the operation of each
detector is correct.
The detector display normally shows ‘0’, turning to a ‘1’ when a
vehicle passes over the loop (or the controller has latched a
pedestrian demand).
Also check that vehicles in adjacent lanes do not activate the loop.
16)
9.6.8
Important: The following causes the MOVA unit to take control of
the Intersection and care should be taken to avoid undue disruption
to traffic flows.
Still using the commissioning screen, force each stage in turn and
check that the controller moves to the required stage and that the
correct stage / phase confirm bits are activated.
17)
9.6.9
Check that the Error Log contains no unexpected entries and then
clear the error log.
667/HB/26568/000
Page 111
Issue 15
3U Traffic Outstation Handbook
Step Section
18)
Action to be Performed
9.6.10 Again using the commissioning screen, put the MOVA unit on
control:
a) Set the ‘MOVA enable’ flag to ‘1’ *
b) Close communications (‘FI’ from the menu)
c) Switch the MOVA unit’s power off and back on
d) Return to the commissioning screen
Check that as the controller changes from stage to stage that the
‘Warm-up Count’ increments.
* MOVA cannot be enabled if the licence number is invalid (9.6.5).
19)
20)
21)
9.6.10 When this count reaches the number of stages plus one (e.g. 6 on a
5-stage controller) the MOVA unit will put itself on control. Check :
a) The ‘On Control’ flag changes from ‘0’ to ‘1’.
b) The ‘TO’ bit changes from ‘0’ to ‘1’.
c) The MOVA unit demands the current (or next) stage.
d) The ‘Error Count’ remains at zero.
9.6.10 Examine the operation of the controller under MOVA control to
ensure that reasonable operation is achieved, e.g. no demands are
been ignored and no excessive queues build-up, and that no faults
have been generated and the error count remains at zero.
9.6.11
Telephone Options
The MOVA unit can be installed with various telephone line options:
a)
Older MOVA units share a single telephone line with a separate
Siemens OMCU, see section 9.4.
b) In a new ‘Integrated OMCU and MOVA unit’, the OMCU
application is always responsible for dialling the RMS Instation.
This would have been checked during the OMCU
commissioning sequence.
c) The MOVA unit can also function without a telephone line.
For both options a) and b), the telephone line should have already
been checked as part of commissioning the OMCU. Therefore, no
additional telephone tests are required for MOVA.
22)
9.6.12 This completes the commissioning steps. The MOVA unit can be
now be left to control the traffic.
Note that for highly critical junctions were the loss of a detector
without the historical flow data could result in serious complications,
it may be necessary to leave the MOVA disabled for one week with
the controller running in its fall-back mode. When the unit has builtup this back-up data, the unit can be enabled. Note that the unit can
be enabled remotely if a telephone line is fitted.

Warning for units running firmware prior to PB681 issue 10
Disconnect the MOVA I/O cables from the back of the unit’s I/O
Board. Always disconnect the I/O cables prior to initialising the unit
and reconnect them after the correct site data has been loaded.
Do not run the unit with I/O cables connected while the default site
data is still present prior to loading the new site data.

9.6.1 Communicating Locally with the MOVA Unit
7)
9.6.1
Connect the PC to the MOVA unit’s local port (the 25 way D-type
connector on the front of the processor board) and start the MOVA
communications application.
Connect a normal controller handset cable (such as the IPT cable 667/1/17523/003)
from the PC to the 25 way port on the front of the MOVA unit. Also see Section 3.9.6.
Start the PC in the usual way. If the PC starts Microsoft Windows, then start an MSDOS Prompt within Windows. At the MS-DOS prompt, type “CD \MOVA” for example
to set the current directory to the location of the MOVA Communications program
and the MOVA data files.
To start the MOVA Communications program enter “MOVAC” (see note 1 below).
The program will ask which PC COM port the serial cable is connected to.
It will then ask whether the MOVA unit is connected locally or remotely via a modem.
Select local communications and then press ‘Return’ until the unit responds.
If nothing is displayed, check that the cable has been connected to the correct serial
COM port and that no other applications on the PC are using the same serial port.
Using PB681 issue 10 onwards, connection is initially to the OMCU handset
application not the MOVA menu application (even if the OMCU application itself is
not required and is unconfigured). To connect through to the MOVA application,
simply enter ‘MOVA’ (or ‘XXM’) while connected to the OMCU handset application.
When ‘FI’ (Finish) is entered from the MOVA menu, the connection will return to the
OMCU handset application.
Before the MOVA unit displays its main menu, it may display its current time and
date. If necessary, correct this using section 9.6.6 on page 119.
If the Instation is communicating remotely with the MOVA unit, then access to MOVA
on site will be refused until the call is complete. Likewise, while an engineer on site is
connected to MOVA, remote communications from the Instation to MOVA are
refused. The Instation will have to try again later.
To close communications with the MOVA unit, type ‘FI’ and press ‘Return’ at the
main menu. This will allow the MOVA unit to tidy-up and close the communications.
The serial cable can now be safely disconnected from the front of the MOVA unit and
the MOVA Communications application can be closed by pressing F10.
Note 1: The previous versions of MOVAC were called MOVAC1 (for COM port 1) and MOVAC2 (for
COM port 2). These have been superseded by the new MOVAC application, which is available from
Siemens on a floppy disk (which also includes MOVA Setup) by quoting the part number
667/1/28054/000 issue 3 or later.

9.6.2 Complete Initialisation
8)
9.6.2
Initialise MOVA by entering the handset command INI=2. If the
OMCU application is not required, enter INI=3 to completely reinitialise the whole unit.
[Prior to issue 10 – set the ‘Phone Home’ flag to 77]
Prior to Issue 10:
To re-initialise the MOVA unit, enter 'LF' to 'Look at Flags' from the MOVA main
menu and then 'S' to 'Set flags'. Then enter 'L' to select the phone home flag. The
MOVA unit will display the current value of the flag (normally zero) and ask for the
new value. Enter '77' and press ‘Return’. The 'Phone Home' flag is described in more
detail in sections 9.7.3 and 9.7.4 that start on page 131.
As always after a flag has been changed, the MOVA unit will display the current
state of all the flags again, but in this case, the unit will reboot before it has chance to
finish this display. After a few seconds, press ‘Return’ to re-establish
communications with the MOVA unit. It will display its current time and date which
will need correcting (see section 9.6.6) since it will have been reset along with the
rest of the MOVA unit's memory.
Issue 10 and later firmwares:
Initialisation of either a PB680 or a PB681 unit is requested using the enhanced INI
handset command:

}
On PB681 firmware, initialising the OMCU application using INI=1 does not clear any
MOVA data. Similarly, initialising the MOVA application using INI=2 does not clear
any OMCU data. However, the complete unit is rebooted after any INI command is
entered.
Complete initialisation effectively forces the ‘first time power-up condition’ by clearing
the entire RAM within the unit. It is recommended that ‘INI=3’ is entered when a new
PB681 unit is first installed to ensure that all data has been initialised. In addition to
clearing the working data of the OMCU and the MOVA applications like INI=1 and
INI=2 respectively, INI=3 also clears additional items which are not cleared by INI=1
and INI=2. This includes the handset commands PLS (section 9.6.3) and MIO
(section 9.6.4), the MOVA licence number (section 9.6.5), the real time clock (section
9.6.6), and all three MOVA site data stores (section 9.6.7).

9.6.3 Phone Line Sharing Facility (PLS)
9)
9.6.3
Ensure the unit has correctly determined whether the Phone Line
Sharing facility to a separate OMCU is required (‘PLS:1’ if enabled
and ‘PLS:0’ if disabled). If not, investigate the reason and correct.
Prior to PB681 issue 10, the ‘phone line sharing’ facility was always enabled and the
PLS handset command was not available. If the facility is not required, the ‘DM’ input
had to be connected to 0V as described in section 9.2.4 on page 105.
The ‘phone line sharing’ facility allows the MOVA unit to share the telephone line with
a separate Siemens OMCU as described in section 9.4 on page 108. The unit will
automatically attempt to determine whether the ‘phone line sharing’ facility is
required after complete initialisation, i.e. INI=3 or first time power-up, as follows:
If no LMU I/O boards are fitted then it implies that the OMCU application within this
PB681 unit is not going to be used, just the MOVA application. Therefore, the ‘phone
line sharing’ facility is enabled by default so it can be connected to a separate
OMCU.
If an LMU I/O board is fitted, then it implies that the OMCU application within this
PB681 unit is going to be used and not a separate OMCU unit. Therefore, the ‘phone
line sharing’ facility is disabled by default.
Regardless of what the unit decides, the ‘phone line sharing’ facility can be disabled
using the handset command “PLS=0” or enabled using the handset command
“PLS=1”.
When a local handset is connected to a unit running PB681 firmware, it will
normally display STCL OMCU+MOVA to identify that the firmware is capable
of providing both the OMCU and MOVA applications. However, if phone line sharing
to a separate OMCU is enabled, the unit will display SIEMENS MOVA to clearly
identify this as the MOVA unit, not the OMCU.

9.6.4 Serial Link Between MOVA and an ST800 (MIO)
10)
9.6.4
If MOVA is to use a Bus / MOVA I/O Board, check that the SOP
handset command shows the correct type of I/O boards have been
detected and that MOVA is using one of them, see page 182.
If MOVA is to use the enhanced serial link to an ST800 but the
OMCU has not been configured, enable the facility manually using
‘MIO=2’ and check that the enhanced serial link is active, i.e.
‘EEL:3’.
The Siemens OMCU has had the option for some time of using an enhanced serial
link to an ST800 traffic controller to monitor the traffic controller. Through this link the
OMCU receives information such as the detector and green states to provide a more
integrated traffic product and to remove the need for almost all of the OMCU’s
external wiring.
This enhanced serial link can now also be used by MOVA in the new integrated
OMCU and MOVA unit (PB681 issue 10 or later). Over this link MOVA obtains the
states of all of its detectors and the stage/phase confirms from the ST800 traffic
controller and passes back the required force bits. Note that the ST800 traffic
controller must be configured to use ‘Serial MOVA’ for this facility to function. See
section 4.2.6 on page 32 for more details.
The unit will automatically attempt to determine whether MOVA should use its Bus /
MOVA I/O Board or the enhanced serial link after complete initialisation, i.e. INI=3 or
first time power-up, as follows:
If one or more Bus / MOVA I/O boards are fitted, then MOVA will initially attempt to
use the first Bus / MOVA I/O board fitted (“MIO:1”).
If only LMU I/O boards are fitted and no Bus / MOVA I/O boards, then MOVA will
initially not attempt to read any inputs or set any outputs (“MIO:0”). If the OMCU is
subsequently configured by the Instation to use the enhanced serial link, then MOVA
will also automatically attempt to use the enhanced 141 link (“MIO:2”).
Regardless of what the unit decides, MOVA can be manually configured to use the
first Bus / MOVA I/O board by entering “MIO=1” or to use the enhanced serial link by
entering “MIO=2”.
If MOVA is required to use a Bus / MOVA I/O board, always
use the handset command SOP to check that the correct I/O
boards have been detected by the firmware and that MOVA is using the first of
these (see page 182). However, if MOVA is required to use the enhanced serial
link, then check for ‘EEL:3’ (section 11.8) and check that the controller
firmware supports, and is configured to use serial MOVA (section 4.2.6). The
fault ‘MSF – MOVA Serial Fault’ will be raised if MOVA cannot communicate
over the link (see section 11.6.2 on page 162 for more details on the
OMCU/RMS fault log).

9.6.5 MOVA Licence Number (LIC)
11)
9.6.5
Enter the correct MOVA licence number, e.g. ‘LIC=1234 5678’.
From PB681 issue 10 onwards, a valid licence number is required before MOVA can
be put on control.
The licence number is unique to each individual site and is made up of two four-digit
numbers separated by a space. To obtain a licence number for a new site, contact
the Siemens RMS Helpdesk at Poole.
You will be asked to provide the following information before a licence number can
be issued:
1) The Pinnacle reference number or Works Order number.
2) The site reference number, e.g. SCN, STS or EM number.
3) The location of the junction, e.g. the names of the intersecting roads.
4) The customer who purchased the MOVA unit, e.g. the local authority.
5) The filename of the MOVA site data.
6) Is it a new MOVA installation or a replacement of an existing* unit?
(* Even if the existing unit was another manufacturer’s MOVA unit)
7) The telephone number of the site.
Once a licence number has been issued for the unit, it should be written down on the
MOVA Installation sheet for the unit and kept in the controller cabinet. Therefore,
should the licence number need to be re-entered, e.g. after replacement of the
complete unit, then the licence number can just be re-entered from that sheet. An
example MOVA Installation sheet is given on pages 228 and 229.

9.6.6 Setting the Time and Date (CT)
12)
9.6.6
Set the time and date in the MOVA unit.
The unit may display its current time and date before displaying its main menu when
connection is first established with the MOVA unit, particularly after a mains power
failure or after being initialised. Alternatively, enter ‘CT’ from the MOVA main menu
to check the unit’s current time and date.
Time is 28/ 9/98 15:32:28
Do you want to change times <Y or N> ?
Typing ‘Y’ then ‘Return’ will allow the time and date to be changed. Any other
character (or ‘Return’ on its own) will be taken as ‘No’.
The time and the date must both be entered as 6-digit numbers, with a leading zero
for values in the range 1 to 9 and without any separators. For example:
Enter time [HrMnSc] 093700
Enter date [DyMoYr] 010998
Note that the new time is only accepted when the ‘Return’ key is pressed to enter the
date. Therefore the time entered should be 10 or 20 seconds ahead to allow time for
the date to be entered and then ‘Return’ can be pressed at the correct time.
After the new date and time have been entered, the current time is displayed again
so that it can be checked that it has been accepted correctly.
After the date and time, the summertime adjustment days in March and October can
be changed. Again, the values must be entered with a leading zero for dates in the
range 1 to 9.
Do you want to enter British Summer Time days <Y or N> y
Enter DAY in MARCH {2 digits - eg 01}, COMMA, DAY in OCTOBER [eg 23,15]
Tip!
The unit’s clock can also be viewed and changed using the OMCU handset
command ‘TOD’, see page 183.

9.6.7 Download New Site Data (RS, LD, CN and DS)
13)
9.6.7
Download the site data into the MOVA unit from the PC and then
clear the MOVA working data as instructed on the screen (only
available from PB681 issue 10 onwards).
Caution: If the new site data contains a different number of links, lanes or stages, or
different time-of-day data then MOVA must be re-initialised. Only if the configuration
is the same as the configuration currently running in the MOVA unit (except for minor
changes to timing values), can the new site data be downloaded without initialising
the unit.
Prior to issue 10, this meant that the I/O cables at the back of the unit MUST be
disconnected while the unit is initialised and the new data loaded. This ensures that
the MOVA unit is not monitoring the junction while running its default data set. When
the new data has been loaded, the I/O cables can be reconnected. With later issues
of firmware, MOVA can be re-initialised after the new site data has been loaded so
the I/O cables do not need to be disconnected.
New site data can be downloaded into the MOVA unit using the ‘Read in Site data’
option – ‘RS’ from the MOVA main menu.
This option is password protected to prevent unauthorised changes to the site data
and can only be attempted locally. The password is case sensitive and is defaulted
to ‘AVOMGO’.
Up to three ‘plans’ can be loaded into the MOVA unit’s memory. Normally, only plan
1 will be used. However, it is possible to configure the MOVA unit to switch between
the plans at different times of day, hence up to three plans, numbered 1 to 3 may
have to be downloaded.
No time of day changes – If only one plan is to be downloaded, then the site data file
name is usually suffixed by the ‘.PT’ extension. Enter the name of site data file
without the ‘.PT’ extension and when asked, select plan number ‘1’. When loading is
complete, the MOVA unit will recognise that this plan data contains no time of day
changes and will not require any more plans to be downloaded.
Three plans – When the site data contains time of day changes, each plan has to be
downloaded into the MOVA unit one after the other. Enter the name of site data file
without the extension and the three plans should be listed on the screen, e.g.
Enter the name of the file without any extension
(or QUIT to abort) ... E12345
1. E12345.P1
2. E12345.P2
3. E12345.P3
key number of the file you wish to transmit . . .
Start with plan 1, and download the site data with the extension ‘.P1’. When that data
has been loaded, the MOVA unit will insist that two more plans be downloaded so
667/HB/26568/000
Page 120
Issue 15
3U Traffic Outstation Handbook
that all three plans in its memory have the same number of stages, links and lanes,
etc.
When the download of a plan is complete, the MOVA unit will display the following:
finished
Reading site data in to plan 1 complete.
Do you want to clear the MOVA working data?
1) If you are about to read in another plan then answer "N".
2) If you have just read in new site data that only makes minor changes and
would like to keep the old working data (e.g. the vehicle flows and the
assessment log) then answer "N".
Note that the new data must contain the same number of stages, links and
lanes and the same time-of-day information as the previous site data.
3) If you have just read in the last of three plans or the one and only plan
for this site, and the unit has just been initialised or this new site
data makes major changes, then answer "Y" so the unit can perform a
clean start with the new site data.
Do you want to clear the MOVA working data <Y or N> ? Y
The MOVA unit will now reboot in order to clear all of its working data, load
the new site data and begin monitoring the intersection.
Note: MOVA will be initially disabled. Use the "Look" screen to put MOVA back
on-control after a warm-up cycle.
Press [Return] to reconnect to the unit after it reboots...
Checking the Site Data
When new site data has been loaded, check it by displaying the site data using the
‘LD’, ‘CN’ and ‘DS’ options.
If more than one plan has been downloaded, the ‘LD’ option allows one of the three
plans to be loaded into the working area. The ‘CN’ option shows the names of the
plans loaded into each of the three backup stores and the name of the plan that
currently resides in the working area. If there are no time of day changes, i.e. only
one plan has been loaded then the MOVA unit will automatically load that plan into
its working area.
The ‘DS’ option displays all the site data of the plan currently residing in the working
area. The MOVA unit pauses after each section, so that the data does not scroll off
the top of the screen.
Important: It is recommended that a 3½” floppy disk containing the up to date site
data file(s) is kept on site so that the site data may be reloaded by field services after
the replacement of the CPU board for example. The disk should be protected from
dust and moisture and should be placed in the coolest part of the controller.

9.6.8
Use the commissioning screen to check for following.
a) MOVA is currently not enabled (MOVA enabled = 0)
b) The Controller is ready* (CRB = 1)
c) The Confirm bits are all set to ‘1’, except for the current stage
which should be set to ‘0’.
Watch the controller perform at least one complete cycle to check
that each stage and phase confirm bit is being activated correctly by
the controller.
* It may be necessary to press the 'Normal' button on the controller's
manual panel before it will activate the 'Controller Ready Bit'.
15)
9.6.8
Also use the commissioning screen to check the operation of each
detector is correct.
The detector display normally shows ‘0’, turning to a ‘1’ when a
vehicle passes over the loop (or the controller has latched a
pedestrian demand).
Also check that vehicles in adjacent lanes do not activate the loop.
The commissioning screen is used extensively to check the operation of the
detectors, the force bits and the confirm bits. To display the commissioning screen,
type ‘LOOK’ from the MOVA Main Menu.
Note that from issue 10 of the firmware, the commissioning screen normally appears
by default since it includes the menu at the bottom (details overleaf).

15 from the controller, and the force bits that the MOVA unit is currently outputting.
The ‘MOVA enabled’ and ‘On Control’ flags and the ‘Warm-up’ and ‘Error’ counts are
described in more detail in section 9.6.10.
For inputs on the Bus MOVA IO card, 0 = input open circuit, 1 = input short circuit.
For semi-integral MOVA, the input sense can be inverted or not, dependant on the
controller configuration.
The ‘Multistage’ flag is set to ‘1’ if the confirm inputs indicate more than one stage is
active, e.g. when the controller has failed or the I/O cables have been disconnected
from the back of the MOVA unit.
The ‘Demanded stage’ entry shows the stage that MOVA is currently demanding, or
would try to demand if it was on control.
The ‘Watchdog’ count should normally increment every half a second and remain in
the range 0 to 20. It is used internally by the MOVA software to ensure that the
various MOVA sub-systems are functioning correctly.
While the commissioning screen is active (and the description of these keys is being
displayed), then the state of the ‘MOVA enabled’ flag and the ‘On Control’ flag can
be toggled by simply pressing ‘M’ or ‘C’ respectively. Similarly, the ‘Error Count’ can
be cleared back to zero by simply pressing ‘Z’.
Pressing ‘X’ will exit the commissioning screen and the MOVA Main Menu will be
displayed. We recommend that you exit the commissioning screen before pressing
‘F1’ to record displayed information such as the error log to a file and press ‘F2’ to
stop recording to the file before typing ‘LOOK’ to restart the commissioning screen.

Important: The following causes the MOVA unit to take control of
the Intersection and care should be taken to avoid undue disruption
to traffic flows.
Still using the commissioning screen, force each stage in turn and
check that the controller moves to the required stage and that the
correct stage / phase confirm bits are activated.
(Remember to press <SPACE> to display the ‘Screen Keys’ before attempting
to use any of the ‘single key’ commissioning screen commands)
To test the force bits and the confirms from the controller, the MOVA unit should first
be switched off-line, i.e. if the ‘MOVA Enabled’ flag is set to ‘1’, press ‘M’.
Then to force a stage simply press the number of the required stage, e.g. press ‘1’
for stage 1 and then press ‘2’ when stage 2 is required.
The MOVA unit will keep forcing the selected stage for about one minute after the
key is pressed. To end the test, press ‘0’.
To exit the commissioning screen, press any key except ‘M’, ‘C’ and ‘Z’ and the
numbers ‘0’ through to ‘9’. You will then be asked to confirm that you wish to exit the
commissioning screen. Press ‘Y’ to exit or any other key to return to the
commissioning screen. Therefore, the simplest way to exit is to press ‘Y’ twice.
9.6.9 The Error Log (DE and CE)
17)
9.6.9
Check that the Error Log contains no unexpected entries and then
clear the error log.
To display the error log, enter ‘DE’ from the main menu,
This displays timestamped reports of any warnings or errors detected by the MOVA
unit. This log may help diagnose the reason why the MOVA unit has gone off control
for example.
At the end of the log, the MOVA unit will display some debug information that can
normally be ignored:

It is recommended that the error log be cleared after each site visit if all entries can
be explained and the unit is functioning normally. Then the engineer making the next
visit to site will only see faults that have occurred since the last visit.

9.6.10 Enabling MOVA Control
18)
9.6.10 Again using the commissioning screen, put the MOVA unit on
control:
a) Set the ‘MOVA enable’ flag to ‘1’ *
b) Close communications (‘FI’ from the menu)
c) Switch the MOVA unit’s power off and back on
d) Return to the commissioning screen
Check that as the controller changes from stage to stage that the
‘Warm-up Count’ increments.
* MOVA cannot be enabled if the licence number is invalid (9.6.5).
19)
20)
9.6.10 When this count reaches the number of stages plus one (e.g. 6 on a
5-stage controller) the MOVA unit will put itself on control. Check :
a) The ‘On Control’ flag changes from ‘0’ to ‘1’.
b) The ‘TO’ bit changes from ‘0’ to ‘1’.
c) The MOVA unit demands the current (or next) stage.
d) The ‘Error Count’ remains at zero.
9.6.10 Examine the operation of the controller under MOVA control to
ensure that reasonable operation is achieved, e.g. no demands are
been ignored and no excessive queues build-up, and that no faults
have been generated and the error count remains at zero.
This section describes in the more detail the ‘MOVA Enabled’ and ‘On Control’ flags
and their interaction with the ‘Error Count’ count and the ‘Warm-up’ count.
Both flags must be set to ‘1’ before MOVA will attempt to control the junction. If either
flag is set to ‘0’, then MOVA will not attempt to control the junction at that time, but
may still be monitoring the traffic flows over its detectors.
The ‘MOVA Enabled’ flag is normally only changed by the user, not by the MOVA
unit itself. It is this flag which must be set to ‘1’ by the user to allow the MOVA unit to
take control of the junction and should be set to ‘0’ to disable the MOVA unit for a
long period of time.
Note that the OMCU will log the fault MOF ‘MOVA Off’ (see section 11.6) and report
‘MOVA Disabled’ to the RMS Instation when MOVA is disabled, i.e. when the ‘MOVA
Enabled’ flag is set to 0.
The ‘On Control’ flag is normally only changed by the MOVA unit itself, although the
user can change its state manually. If the ‘MOVA Enabled’ flag is set, then following
the warm-up cycle, the MOVA unit will set the ‘On Control’ flag and start to control
the junction.
During the warm-up cycle, the MOVA unit will increment the warm-up count on the
commissioning screen every time a new stage starts. When this count reaches the
667/HB/26568/000
Page 126
Issue 15
3U Traffic Outstation Handbook
number of stages plus one (e.g. 6 on a 5-stage junction) then the warm-up cycle is
said to be complete. This warm-up cycle allows the MOVA unit to gather information
about the junction before it takes control.
Following various fault conditions, the MOVA may put itself off control by clearing the
‘On Control’ flag and incrementing its ‘Error Count’. Depending on the nature of the
fault, the MOVA unit will increment the ‘Error Count’ by one, two or five.
Every hour on the hour the MOVA unit decrements the ‘Error Count’ unless it has
reached the value of 20 when the unit will reset the ‘MOVA Enabled’ flag back to 0.
9.6.11 Modem Commissioning
21)
9.6.11
Telephone Options
The MOVA unit can be installed with various telephone line options:
a)
Older MOVA units share a single telephone line with a separate
Siemens OMCU, see section 9.4.
b) In a new ‘Integrated OMCU and MOVA unit’, the OMCU
application is always responsible for dialling the RMS Instation.
This would have been checked during the OMCU
commissioning sequence.
c) The MOVA unit can also function without a telephone line.
For both options a) and b), the telephone line should have already
been checked as part of commissioning the OMCU. Therefore, no
additional telephone tests are required for MOVA.
For more information on communicating remotely with the MOVA, see sections 9.7.1
and 9.7.2, which start on page 128.
9.6.12 Completing MOVA Commissioning
To close communications with the MOVA unit, type ‘FI’ at the main menu. This will
allow the MOVA unit to tidy-up and close the communications. The serial cable can
now be safely disconnected from the front of the MOVA unit and the MOVA
Communications application can be closed by pressing F10.

9.7 MOVA Communications Notes
Assistance on communicating locally with the MOVA unit during commissioning is
provided in the previous section within the appropriate steps in the commissioning
checklist, e.g. section 9.6.1 on page 114.
This section provides information on communicating remotely with a Siemens MOVA
unit via the telephone network and describes some of the options which may be
useful once MOVA is functioning normally.
It does not cover all the aspects of communicating with a MOVA unit as these are
covered in the TRL documentation, see section 1.3. It is primarily concerned with
how to perform the tasks required to install, commission and maintain the Siemens
MOVA unit and how it differs from the other MOVA units on the market.
9.7.1 Communicating Remotely (Not Phone Line Sharing)
If the MOVA unit at the outstation is sharing the same telephone line as a separate
Siemens OMCU, as described in section 9.4 on page 108, then refer to section 9.7.2
instead.
To communicate remotely with the MOVA unit requires the unit to be fitted with a
modem connected to the PSTN line in the controller cabinet. The Instation will also
require a modem connected to the PSTN telephone network and to a serial COM
port on the PC at the Instation running the same MOVA communications program as
used locally.
From the RMS Instation, simply select ‘Enable MOVA’ from the Outputs menu. See
its associated help for assistance. The unit can also be contacted remotely from any
PC with a modem as follows:
Start the PC and communications program using the instructions in section 9.6.1,
which start on page 114, except when the program starts, select remote rather than
local communications.
Before communicating with the MOVA unit, the modem connected to the PC must be
instructed to ring-up the MOVA unit first. Note that the MOVA unit will automatically
configure its modem to answer any telephone calls.
Reset the modem by typing ‘ATZ’ and wait for an ‘Ok’ response from the modem.
As instructed on the screen, enter ‘AT+MS=2,0’ to select V22bis protocol. If the
modem responds with an error, it may be because it does not recognise that
command. If so, try the older version of the command ‘ATF5’ or consult the modem’s
documentation.
Enter ‘ATD’ followed by the telephone number of the site. Check whether an STD
code is required and also check whether ‘9’, for example, needs to be dialled first to
obtain an outside line.
To summarise, the following should appear on the screen…
667/HB/26568/000
Page 128
Issue 15
3U Traffic Outstation Handbook
ATZ .........................................to reset the modem
Ok ...........................................accepted by the modem

Ok ...........................................accepted by the modem
ATD 9 01202 123456 .........ask the modem to dial the given number
CONNECT .................................response from modem indicating connection made
Please wait ........................message from MOVA application*
* If dialling a single integrated OMCU/MOVA unit, press ‘Return’ three times after the
‘connect’ message from the modem to connect to the MOVA application rather
than the RMS OMCU application.
After a short delay, the MOVA unit will then ask for the password to validate remote
access. The password is defaulted to ‘AVOMIN’ although it can be changed.
Once the password has been accepted, the MOVA unit communicates remotely in
exactly the same way as it does locally. The only exception is that downloading plans
and manually forcing stages are prohibited during remote communications.
To end communications with the MOVA unit, select the ‘FI - Finish’ option from the
MOVA unit’s main menu. This allows the MOVA unit to tidy-up and close the
communications and hang-up, resulting in ‘NO CARRIER’ being displayed at the
Instation. At this point, press F10 to close the MOVA Communications application.
9.7.2 Communicating Remotely with a Phone Line Sharing MOVA Unit
When a Siemens MOVA unit and a separate Siemens OMCU unit share the same
telephone line, see section 9.4 on page 108, then the OMCU can be considered as
‘in charge’ of the telephone line, in that:
1) The OMCU will normally answer all telephone calls, and,
2) If the MOVA unit detects a fault and wishes to ‘phone home’, then it simply passes
the event to the OMCU and it is the OMCU which reports it to the RMS Instation.
Therefore, to communicate remotely with the MOVA unit, the OMCU must be
contacted first to request that it allow the MOVA unit to answer the next telephone
call.
When the call to the MOVA unit has been completed successfully, the OMCU will
automatically regain control of the telephone line and answer any subsequent calls.
If a call to the MOVA unit is not completed successfully, e.g. due to an excessively
noisy telephone line, then subsequent attempts can be made to contact the MOVA
unit without first contacting the OMCU.
However, the OMCU will only allow calls to the MOVA unit for five minutes. After this
time the OMCU will regain control of the telephone line and answer any subsequent
667/HB/26568/000
Page 129
Issue 15
3U Traffic Outstation Handbook
calls. This does not limit MOVA calls to five minutes since any call that is in progress
between the Instation and the MOVA unit will not be terminated.
In the unlikely event that the OMCU detects an urgent fault while a call is in progress
between the Instation and the MOVA unit, then the OMCU will interrupt the MOVA
unit’s telephone call to report the fault to the RMS Instation.
Contacting the MOVA unit from an RMS Instation:
Select the ‘Enable MOVA’ option under the ‘Outputs’ menu in the RMS
Instation application to contact the OMCU and allow subsequent calls to be
answered by the MOVA unit.
Once this call to the OMCU has finished, the MOVA unit can be called as if it
had the telephone line to itself by following the instructions in section 9.7.1,
and selecting the ‘MOVA Communications’ application from the ‘Tools’ menu
also within RMS to start the MOVA communications application.
NOTE: If the intention is to use the same serial COM port and modem as
used by RMS to also communicate with the MOVA unit, then the RMS comms
window should be closed before starting the MOVA Communications
application and then re-started when the MOVA application is closed.
Contacting the MOVA unit without an RMS Instation:
If the RMS Instation is not available, then the following MS-DOS application
also supplied on issue 2 and later versions of the MOVA Communications
Disk 667/1/28054/000 will contact the OMCU and allow subsequent calls to be
answered by the MOVA unit.
Prior to starting the MOVA communications application, enter the following to
run the 'STCLMOVA' application:
or
STCLMOVA 1
STCLMOVA 2
- if the modem is connected to COM port 1
- if the modem is connected to COM port 2
Once the application has successfully reached the OMCU, the MOVA unit can
then be called as if it had the telephone line to itself as in section 9.7.1.
Note that the parameter (‘1’ or ‘2’) may be omitted in which case the
application will use the COM port specified in the file SQTSETUP.SAV. For
more information see the ‘ReadMe.TXT’ file also supplied on the disk.
Closing Communications:
To end communications with the MOVA unit, select the ‘FI’ option from the
MOVA unit’s main menu.
This allows the MOVA unit to tidy-up, close the communications and hang-up,
resulting in ‘NO CARRIER’ being displayed at the Instation. At this point,
press F10 to close the MOVA Communications application.
667/HB/26568/000
Page 130
Issue 15
3U Traffic Outstation Handbook
When a successful call to MOVA is finished, the MOVA unit will switch off the
power to its modem and return complete control of the telephone line to the
OMCU again. Subsequent calls are therefore answered by the OMCU even if
the call was completed within the five-minute time-out period described above.
9.7.3 MOVA Flags (LF and SF)
The MOVA flags can be viewed, and then changed, using the LF (Look at Flags)
option from the main menu:

flags are set directly by other options from the main menu.
The Look Flags sub-menu gives five options. In reverse order these are:
Return to MAIN MENU <R>
The fifth and final option is used to return to the main menu.
Clear force bits <C>
Set Force bits <F>
The third and forth options allow force bits to be tested. This option is only provided
for backward compatibility as it is recommended that the commissioning screen be
used to test the force bits.
Look at Flags <L>
The second option displays all the flags and the menu again. Use this option to
‘refresh’ the display, e.g. when looking for a change of state of a particular flag.

Set Flags <S>
The first option can also be called directly from the main menu by typing ‘SF’ rather
than ‘LF’. This option allows some of the flags to be changed:
SET FLAGS :

ENTER CHOICE (or Q to quit) ...
The ‘error count’ and the ‘on control’ and ‘VA/MOVA’ flags are more easily modified
using the commissioning screen which is described in section 9.6. The ‘phone home’
flag is covered in the following section below.
The MOVA messages, hourly flow, assessment and error log flags should not need
to be changed as viewing these logs should be performed using the explicit options
from the main menu. However, the logging of hourly flow and assessment data can
be switched on and off using these flags. By default, the MOVA unit records both
normal assessment data and hourly flow data* in its assessment log. Changing the
setting of these two flags can alter this.
* Prior to issue 10, hourly flow data was not logged by default.
For example, to get the MOVA unit to also record hourly flow data in its assessment
log, type ‘F’ and press ‘Return’. The MOVA unit will then display the current value of
the flag and ask for the new value. At this point, enter ‘1’ followed by ‘Return’ to set
the hourly flow flag to ‘1’. This can be confirmed when the MOVA unit displays all the
flags again.
ENTER CHOICE (or Q to quit) ... F
FLAG(23) = 0 Enter new value =
9.7.4 Phone Home Flag
The phone home flag is one of the many flags that can be viewed using the LF (Look
at Flags) option from the main menu, see above.
If the phone home flag is set to ‘99’, either by the MOVA unit itself or directly by the
user using the ‘Set Flags’ option, then the MOVA unit will ‘Phone Home’.
Regardless of the firmware issue, if the unit is connected to a separate Siemens 3U
OMCU for phone line sharing, the ‘event’ is passed to the separate OMCU unit and
the ‘Phone Home’ flag is cleared.
If the MOVA unit is not connected to separate OMCU unit, then its actions depend
on the firmware issue…
667/HB/26568/000
Page 132
Issue 15
3U Traffic Outstation Handbook
Prior to issue 10 firmware, the MOVA application itself would attempt to phone a
modem connected to a printer for example. When the call has been made, the flag is
returned to its original value, normally zero.
From issue 10 onwards, the OMCU application within the unit will report ‘MPH MOVA Phone Home’ to the RMS Instation (see section 11.6.2 which starts on page
162); the MOVA application does not actually phone home itself. In this case, the
phone home flag returns to its original value, normally zero, as soon as the ‘MPH MOVA Phone Home’ fault has been passed to the OMCU application. The fault will
remain active in the OMCU (and at the RMS Instation) until it is manually cleared by
the operator at the Instation (and the Instation has phoned the OMCU).
Note that if the telephone line sharing system is being used, the flag will return to
zero as soon as the ‘fault’ has been passed to the separate Siemens OMCU. If the
value remains at ‘99’ then the wiring between the MOVA unit and the OMCU should
be checked. Also check that the OMCU contains the relevant special conditioning to
handle the DM and MF I/O lines. See section 9.4 which starts on page 108.
Normally, the MOVA unit will only ‘phone home’ when it has detected an
unrecoverable error, e.g. when its error count has reached or exceeded 20
preventing the MOVA unit putting itself back on-line.
However, by setting the ‘Phone Home’ flag to a value in the range 1 to 20, the user
can force the MOVA unit to phone home whenever the error count reaches this limit.
For example, it may be useful to set the ‘Phone Home’ flag to ‘1’ to force a MOVA
unit to ‘Phone Home’ whenever the error count is set to ‘1’ or higher, i.e. whenever
the unit detects any fault. Alternatively, setting the flag to ‘5’ would force the MOVA
unit to ‘Phone Home’ only after more serious faults.
Prior to issue 10, the 'Phone Home' flag could also be used to re-initialise the MOVA
unit, see section 9.6.2 on page 115.
9.7.5 View MOVA Messages (VM)
The commissioning screen is mainly concerned with checking the I/O connections to
the MOVA unit. To aid diagnosis of run-time problems with the MOVA algorithm,
MOVA produces a series of output messages.
To view these MOVA messages, select the ‘VM - View MOVA Messages’ option
from the main menu:
ENTER OPTION . . .
VM
Enter number of minutes messages output for <1-9> or 0 for continuous
(NB - Press ANY key to pause messages) ENTER NUMBER ...
Abandon messages now? (y/n)Y
Return to continue
Enter ‘0’ so that the MOVA unit outputs messages continuously since the messages
can be stopped at any time by simply pressing any key and then pressing ‘Y’ to
667/HB/26568/000
Page 133
Issue 15
3U Traffic Outstation Handbook
confirm that you do wish to stop the messages. The main menu will re-appear after
‘Return’ is pressed.
The messages themselves are by no means self-explanatory because it is essential
to minimise the amount of text within each message.
Once the messages start appearing, press the ‘F3’ key and the MOVA
Communications application will show a full screen display of the information it
receives in the messages in a much more understandable form.
In fact, so much information is contained within the messages that two screens are
required to show it all. Press the ‘F5’ key to toggle between the two screens.
To exit view messages, press the ‘F4’ key to close down the full screen displays and
then press any key to inform the MOVA unit that no more messages are required.
9.7.6 Other Menu Options
The ‘LP - Load data from Prom’ option does not perform any function on the
Siemens MOVA unit as there is no PROM data store. All of the site data resides in
battery backed RAM.
Details about displaying the average flows and the assessment log can be found in
the document AG12 available from TRL.
The remaining menu items are concerned with printing. These options are not
applicable to the Siemens MOVA unit since it does not have a printer port. If
printouts of the various logs are required, then the log should be displayed on the
screen as normal and the output recorded to a file on the PC. From the main menu,
press the ‘F8’ key to display the MOVA Communications menu which shows that ‘F1’
and ‘F2’ can be used to write the screen output to a file on the PC.

10. CAR PARK COUNT and PAKNET
10.1 Overview
The car park monitor facility is primarily designed for use with the PAKNET
communication interface and a SIESpace Instation. The current occupancy of a car
park is returned to the SIESpace Instation periodically. This information can then be
used by the Instation to guide vehicles to car parks that have spaces.

The main functions of the car park monitoring are as follows:
• To monitor car park entry and exit loop inputs
• To generate a difference count indicating the current occupancy of the car
park
• To report car park occupancy to a Central Office based on occupancy
threshold monitoring
• To report car park occupancy to a Central Office based on timetable events
• To report car park occupancy to a Central Office when requested by a
Central Office
• To report faulty loops and clearances to a Central Office
• To report power-fail and power restore to a Central Office
• To report cabinet door state to a Central Office
• To set the car park occupancy when requested by a Central Office to
specified value
667/HB/26568/000
Page 135
Issue 15
3U Traffic Outstation Handbook
• To modify specific Car Park facility configuration data when requested by a
Central Office
• To provide handset commands to modify the Car Park facility configuration
data
10.2 OMCU Status Message to SIESpace
The OMCU generates the same status report format regardless of the reason for
generating the status report. The status report contains the following information:
• Occupancy status
• Occupancy
• Vehicle count for each configured loop
• DFM state for each configured loop
• Ramp mode
• Car park state
• Door state
• Power fail
• Emergency input state
When the Central Office resets the difference count, the OMCU replies as above
with the occupancy and the vehicle count for each loop set to 0.
A status message is automatically transmitted to the SIESpace Instation when any of
the following events occur:
• Cabinet Door is opened or closed
• Power fail is detected or restored
• Routine Poll is requested
• Ramp-up or Ramp-down mode is entered
• Car park state changes (i.e. Spaces, Almost Full, Full , Closed)
10.2.1 Routine Poll
The OMCU contains a timetable that indicates the periodic rate at which status
messages must be transmitted to the Instation.
This ensures that the Instation will receive a status message with a minimum time
interval specified in the table. If an event occurs that forces a status message to be
transmitted (e.g. cabinet door is opened) then the routine poll timer is reset. This
ensures that a routine poll is not transmitted just after the status as a result of the
event.
The timetable is initialised to the values indicated in section 10.4.1; these settings
can only be modified using a SIESpace Instation.
10.2.2 Loss of comms to PAKNET pad
On loss of communications with the PAKNET pad, the OMCU switches OFF / ON
the pad in an attempt to re-establish comms. The longer that comms is lost, the less
frequently retries are attempted.
667/HB/26568/000
Page 136
Issue 15

-
Initially, every 10 seconds for 10 attempts
Then, every hour for 5 attempts
Then, every 24 hours until comms is re-established
Prior to PB680 issue 13 firmware, comms is only retried every 10 seconds for 10
attempts.

system.

OMCU Car Park Thresholds
The OMCU maintains 3 distinct states – ‘SPACES’, ‘ALMOST FULL’ and ‘FULL’.
The car park occupancy is compared to these thresholds to determine whether a
state transition is required.
• The ‘SPACES’ state is set when the almost full decreasing threshold is crossed
from the ‘ALMOST FULL’ or ‘FULL’ states.
• The ‘ALMOST FULL’ state is set when the almost full increasing threshold is
crossed from the ‘SPACES’ state or when the full decreasing threshold is crossed
from the ‘FULL’ state.
• The ‘FULL’ state is set when the full increasing threshold is crossed from the
‘SPACES’ or the ‘ALMOST FULL’ states.
A status report is sent to the Central Office whenever any one of these thresholds is
crossed.
667/HB/26568/000
Page 137
Issue 15
3U Traffic Outstation Handbook
Extrapolation
A straight line extrapolation is made N minutes into the future to assess whether the
car park is filling or emptying at a fast enough rate to require more frequent status
reports to the Central Office.
The extrapolation is based on two occupancy values (a) the current occupancy and
(b) the occupancy from M minutes earlier. M is the fill rate calculation period
(handset command FCP).
The value of N depends on the state:
• If the state is ‘FULL’ then N is set to the ramp down time threshold.
• If the state is ‘SPACES’ or ‘ALMOST FULL’ then N is set to the ramp up time
threshold.
If the state is ‘SPACES’ or ‘ALMOST FULL’ and the car park is filling fast enough so
that the ‘FULL’ state would be reached in N minutes. Then status reports are sent to
the Central Office at X minute intervals (ramp up mode) where X is set to the ramp
up period. The first status report is sent as soon as the decision is taken to enter
ramp up mode.
If the fill rate changes so that the ‘FULL’ state would not be reached within N minutes
then status reports are no longer sent to the Central Office at X minute intervals. If
the occupancy reaches the ‘FULL’ state, status reports are no longer sent at X
minute intervals.

down period. The first status report is sent as soon as the decision is taken to enter
ramp down mode.
If the emptying rate changes so that the ALMOST FULL state would not be reached
within N minutes then status reports are no longer sent to the Central Office at X
minute intervals. If the occupancy reaches the almost FULL state, status reports are
no longer sent at X minute intervals.
The Historical Occupancy is calculated and stored at 1-minute intervals.

10.4.2 Detector Fault Monitoring
Each of the car park entry and exit loops can be configured to have detector fault
monitoring, by default this facility is disabled.
Each loop can provide a separate detector ‘Active’ and ‘Inactive’ time, the timing
range is 0 to 255 minutes and hours respectively. Handset command CPL is used to
set-up these times.
If the detector remains in either the ‘active’ or ‘inactive’ state for longer than the
configured time then a failure is recorded. Once a DFM fault has been reported it
remains active even if the detector starts to operate again.
To clear the fault firstly the detector fault must be fixed and have started to operate
again (i.e. it has changed state at least once). Handset command RDF=1 must then
be entered to clear the fault, the handset display will change to RDF:0 once all faults
have been cleared (this may take up to 1 minute).
10.4.3 PAKNET Configuration
By default the PAKNET communication protocol is disabled. The following handset
parameters have to be set-up to enable this facility.
RCA – Remote Comm’s user address is the 14-character address of the Instation.
RCT – Comm’s type – set to PAKNET.
ADR – Each OMCU on a car park system has its own unique address.
10.5 Installation
10.5.1 Interface Connector
An additional interface connector must be placed between the OMU modem cable
and the PAKNET pad.
The pin outs for this connector are as follows :

10.5.2 Radio Pad Power
The power to the radio pad is controlled by the OMCU. This allows the pad to be
switched OFF / ON if a malfunction is detected.
667/HB/26568/000
Page 140
Issue 15
3U Traffic Outstation Handbook
The radio pad requires a 12V DC supply of power. This is supplied from the OMCU
(PL1 connector pin 29). This power is passed through a relay mounted on a Din rail
within the cabinet. This relay is controlled via an output from the OMCU (PL1
connector pins 27 and 28). The OMCU can then switch this output to turn the radio
pad power Off/On.
Note: The radio pad must not be powered directly from the OMCU output as this
current required is greater than the output relay’s specification.

10.5.3 Door Switch
A Door switch can be provided to indicate to the Instation when the cabinet door has
been opened. This input is connected to one of the low voltage inputs on the OMCU.
By default the door switch is assigned to input 16 (PL3 pins 15 and 16)
Handset command DOR can be used to modify the OMCU input assigned to this
facility.
10.5.4 Count Detector Loops
Detectors are wired into the required count loops, these should be connected as
detailed in section 5.6.4.

11. HANDSET FACILITIES
11.1 INTRODUCTION
Access to the status information is gained by entering codes on an approved
handset and interpreting the response on the display.
The handset port connector is a 25-way female D-type and operates at 1200 baud,
even parity, 1 stop bit. Firmware PB680 issue 5 and later will auto-baud to 1200,
9600 or 19200 baud, on first receiving characters after the handset is plugged in.
This section lists all the handset codes, together with their data ranges and access
levels for the OMCU, Bus Processor, Car Park and MOVA* applications.
* Prior to PB681 issue 10, none of the handset commands listed in this section were
available in a MOVA unit. All functions were provided solely from the MOVA menu.
The following list gives a summary of all the Handset codes in an alphabetical order,
for use as a quick lookup reference guide:

11.1.1 Command Format
All operator commands start with a three letter command code indicating the
parameter to the monitored or changed. This code may constitute the complete
command, e.g. KDB for controller ‘DIM/BRIGHT’ state, or may be followed by one or
two indexes indicating a specific parameter within the category determined by the
code. For example, analogue data of specified input KAC requires to identify both the
channel and the voltage or current on that ADC channel.
For read operations, following typing of the command code and any indices if
applicable, operation of the ENTER (or ‘RETURN’) key terminates the command.
For write operations an equals sign ‘=’ followed by the parameter required is added
to the read command before selecting ENTER (or ‘RETURN’). Thus, for example:
- To read the analogue data the command is:
- To reset the Power-up statistics data (first element of five) the command is:
667/HB/26568/000
Page 147
Issue 15
3U Traffic Outstation Handbook
The ‘+’ (or ‘.+’) and ‘-‘ (or ‘.-‘) keys may be used after a basic read command has
been entered to enable the MINOR index (or MAJOR index) to be modified to scan
the OMCU.
11.1.2 Display Format
The two basic display formats are:
• Echo display that is simply an echo of the information typed.
• Response display generated by the OMCU when the command is terminated by
operating the ENTER (or ‘RETURN’) key or the ‘+’ (or ‘.+’) keys.
The response displays include:
• Read response display comprising a repeat of the command with spaces between
the fields and a colon and data added, e.g.
PUD 0:0
• Write response display in which the command is repeated with the ‘=‘ replaced
with a colon, i.e. identical to the corresponding read response display.
• Error response display in which the command is repeated with an asterisk and
error code added, e.g.
PUD AB*S
Indicating the command has a syntax error and should be repeated correctly.
Other display formats comprise those without the command repeated due to lack of
display character width; e.g. response to monitor digital inputs command DIP. Where
the command deviates from the normal in either of these respects this is indicated in
the command table.
11.1.3 Read Procedure (Monitor Existing Data)
1. Plug the handset into the socket on front of the OMCU.
2. When the OMCU displays the prompt character ‘-’, type out the appropriate
command and any index necessary, e.g. to determine the DIM/BRIGHT state of
the controllers signal lamps enter KDB to produce the display:
KDB
667/HB/26568/000
Page 148
Issue 15
3U Traffic Outstation Handbook
3. Terminate the command by operating the ENTER (or ‘RETURN’) key. The OMCU
responds by repeating the display with a colon and the required data. (e.g. Bright
state in this example), i.e. KDB : 1
4. Repeat Steps 2 and 3 for each operation using the ‘+’ (or ‘.+’) or ‘-‘ (or ‘.-’) keys
where possible to reduce key entry.
NOTE:
If the OMCU detects an error on interrogating the command, instead of the
normal response, the OMCU repeats the command display with an
asterisk and error code added. The error codes used are listed in Table
11.2.
667/HB/26568/000
Page 149
Issue 15
3U Traffic Outstation Handbook
11.1.4 Write Procedure (Change Existing Data)
1. Plug the handset into the socket on front of the OMCU.
2. When the OMCU displays the prompt character ‘-’, carry out the appropriate
level access enabling operation (described in information supplied separately to
each OMCU user).
Type out the required command code, any index or indexes necessary, followed
by ‘=’ and the required value, e.g. to reset the Power Up state data (second
element), enter ‘PUD 1=0’ which will be echoed back to the handset
3. Terminate the command by operating the ENTER (or ‘RETURN’) key. The OMCU
responds to confirm the change by repeating the display with = changed to colon
as shown below:
PUD 1:0
4. Repeat step 3 and 4 for each operation using the ‘+’ (or ‘.+’) or ‘-‘ (or ‘.-‘) key
where possible to reduce key entry.
NOTE: If the OMCU detects an error on interrogating the command instead of the
normal display an error display comprising the command display with an
asterisk and error code added. The error codes used are listed in Table
11.2.
11.1.5 Alternative Write Procedure (Change Data Following Read)
With access enabled as appropriate, a write procedure may be carried out following
reading of the information to be changed by typing = followed by the new value. This
immediately replaces the colon and the old value in the display. On operation of the
ENTER (or ‘RETURN’) key to terminate the instruction, the OMCU repeats the
display with = replace by a colon.
11.1.6 Switchable Handset Facility
It is possible to store up to 10 handset commands, such that any of these commands
may be subsequently recalled by pressing the “.” (dot) key followed by the
appropriate number. In this way it is possible to simply switch between one handset
display and another. (See note)
Setting Up

The facility is not restricted to just the commands indicated above; any valid handset
facility may be entered in any of the pointers in any order.
Note: On some handset commands it is not advisable to duplicate the command in
two or more dot buffers. If this is done then access to the other duplicate command
buffers will not be serviced. The commands affected are identified in the mnemonic
code box.

11.6.1 Fault Diagnostics (FDC)
This handset command allows access to general fault monitoring statistics.
This data is arranged in two sets accessed by the major & minor Indices:
Minor Index : 0
- Current information
Minor Index : 1
- Historic information
As each condition occurs the relevant count is incremented and when the number of
characters received reaches its maximum value (FFFFH) then all counts are copied
to the ‘historic log’ (minor index = 1) and then resets to zero.
When the OMCU is first installed all the data is reset to 0.
Note: All count information is displayed in HEX
FORMAT:
FDC <m> <n>
Here <m> is the ‘major index’ and <n> is the ‘minor index’.
Major Index:
0
Number of reports entered into OMCU Fault Log.
1

3
Number of Dial requests made to the Instation.
4
Number of Fault Log Buffer overflows (due to too
many unreported faults).
5
Number of Fault Log timer overflows (due to long
periods of time between faults).
6
Number of Fault Log resets received
7
Number of Fault Log resets received for
unreported faults.
8

11.6.2 General Fault Data Display Format
The FLT command displays a list of current faults (use + and - to scroll through the
list). The format is as follows:
FLT:!VLF A 0
Fault data
Fault code
‘!’= Urgent fault
‘ ’= Non-urgent fault
It should be noted that fault reports are only generated when the limits (as defined in
the OMCU configuration data) are exceeded.
Where PB680 issue 5 (or later) firmware is fitted, the FLG command is also
available. This command displays a time-stamped log of OMCU faults and events.
The fault codes used with the FLT and FLG commands are given in the following
table.

11.7.1 Call Disconnect Cause Statistics Log (CDC)
Whenever the OMCU disconnects itself from the telephone line the reason for that
disconnection is stored in a log. By viewing this information the engineer can
determine such things as:
→ The number of calls;
→ The quality of the line;
→ Whether there has been any unauthorised access to the OMCU.
The log is arranged in two groups - one is the current log the other is the historic log.
The current log is copied to the historic log whenever any counter in the current log
overflows.
FORMAT:

The OMCU detected a supply ‘brown-out’ and
terminated the call that was in progress at the time.
If the maintenance access code has been entered the log data can be reset by
entering ‘=0’.
11.7.2 Call Termination Record (CTR)
This log provides the engineer with information relating to the success of fault record
transfers to the Instation. Again as in the CDC command describes above the major
index provides access to both the historic and current log.
FORMAT:

11.7.4 Message Diagnostic Data (MDC)
During any Instation - Outstation (OMCU) communication all characters and
messages are checked for errors. This log stores these together with a total count of
all good characters received.
Again as in previous logs two sets are stored one for current data (miner index = 0)
and one for historic data (minor index = 1)
As each condition occurs the relevant count is incremented and when the number of
characters received reaches its maximum value (FFFFH) then all counts are copied
to the ‘historic log’ (minor index = 1) and then reset to zero. If any count reaches its
maximum value whilst the character count is below its maximum limit then the value
‘locks’ at FFFFH.
Note: All count information is displayed in HEX.

Time currently being received from the radio clock
Status: DEC = Decoding, IDL = Idle
Seconds count - incremented as the time signal is
decoded over a 1-minute period
With a correctly operating radio clock, the time of last synchronisation will be within
one or two minutes of the current time, and the MIS, RFQ and LNK error counts will
be zero.
667/HB/26568/000
Page 185
Issue 15
3U Traffic Outstation Handbook
The OMCU internal clock is only synchronised to the radio clock time signal when
the radio clock signal has been received correctly over two consecutive minutes and
the RF quality indicated by the radio clock is good.
After power on, the radio clock takes 10 to 15 minutes to indicate good RF quality to
the OMCU. During this period, the RFQ error count is incremented. The error counts
are cleared when the OMCU synchronises to the radio clock signal.
In times of poor radio propagation it may not be possible for the clock unit to
synchronise the OMCU. However good reception is only required for a few minutes
each day to maintain the accuracy of the OMCU’s real time clock.
As an additional installation aid a signal reception indicator is present in the Radio
Clock unit. When the ‘test switch’ within the Radio Clock is pressed the Reception
Indication LED will flash regularly for about 1 minute if good signal strength is
present. If random flashes are displayed then the reception is poor and the clock unit
may not be correctly orientated.

11.11 Bus Config Notes
All configuration commands take effect as soon as they are entered, except for POC.
The POC command changes the RAM data, but the hardware serial ports are not reconfigured until the POS command is used or the OMCU is powered off then on.
When the handset connection is terminated, system log entry(s) are created
indicating the changed area(s), with change codes allocated to each handset
command used, as follows:
0 = BID, SRC, ASS
1 = MAP, ACT
2 = POC, POS
3 = BFT, BFO, BFR
4 = LAN
5 = LDV
6 = RCI, RCR, RCD, RTO
7 = RET
8 = CUS, ARM, ARV, TAF, DFA
Thus a change to all the data in the output association list will only result in a single
log entry.

11.14.2.1 Influence Function (IFN)
Each influence function is described below:
Type Explanation
0
Deactivate - Deactivate all outputs associated with this output action stream
1
Activate - Deactivate any existing outputs for the stream and activate the
specified output action. NB: Any conditional activations (influence type 2) for
the stream are discarded.
2
Conditional - If the condition specified for the output action is true or
becomes true, then de-activate any existing outputs for the stream and
activate the specified output action. These outputs remain active even if the
condition is removed. NB: Any conditional activations (influence type 2) for
the stream are discarded.
3
Freeze - The currently active output action on the stream is held. Only
applicable following influence type 2.
11.14.2.2 Timeswitch settings (TSW)
TSW N 0 : <Day Code> (<Abbreviation>)
This first item specifies on which day or days the timetable event applies.
Day Codes 0 to 15 specify a normal day or normal days of the week, e.g. ‘TSW N
0:3 (TUE)’ since code 3 is usually configured to mean just on Tuesdays, see TDY.
Day Codes 16 to 99 are ‘Special Days’ see TSD.
If ‘Special Holiday Periods’ are configured using TSH then:
Day Codes 0 to 15 only run outside these holiday periods.
Day Codes 100 to 115 only run within these holiday periods.
Day Codes 200 to 215 run regardless of holiday periods.
TSW N 1 : <0 to 23 hours>
TSW N 2 : <0 to 59 minutes>
TSW N 3 : <0 to 59 seconds>
The above items specify at which time the timetable event applies.
TSW N 4 : <Operation Code 0 to 4>
TSW N 5 : <Additional Operation Code Parameter>
These last two items specify the operation that should be carried out. The valid
Operation Codes are described as follows :
TSW N 4 : 0
TSW N 5 : <Don’t Care>
The operation code ‘0’ tells the OMCU to isolate, i.e. drop out of CLF (cableless link
facility) mode, returning to VA mode for example.
TSW N 4 : 1
TSW N 5 : <CLF Plan Number 0 to 15>
The operation code ‘1’ tells the OMCU to start the CLF plan specified by ‘TSW N 5’.

‘TSW N 5’, without affecting any other timeswitches.
TSW N 4 : 4
TSW N 5 : <TimeSwitch Event Number 0 to 31>

Identifies the detect conditions for
which a VC event is logged when
the detection condition is satisfied.
Bit set to a 1 indicates event
logged.
The least significant bit
corresponds to detect condition 0,
the most significant bit
corresponds to detect condition
15.

11.18.2 Operations Log Capacity
The Operations Log holds approximately 12,000 VC events if the processor board is
fitted with large RAM chips (667/1/26601/002). Only around 500 entries can be
recorded if the small RAM chips are fitted (667/1/26601/001, now obsolete).
The following table provides a summary of Operations Log capacities containing TD
events only for typical configurations assuming a 1 minute averaging period. For
other averaging periods the log capacity is increased.

of greater than 25.5s is limited to 25.5s.
Examples
23-JAN-02 16:30:00 L:12 CAR 5.23m 50kph 6.2s O:1
A vehicle classed as a CAR on site 1 lane 2 was recorded with a length of 5.23m, a
speed of 52kph and a headway of 6.2s. The detection invoked output action 0.
23-JAN-02 16:32:00 L:12 BIG THING 12.01m 70kph 25.5s O:100F
A vehicle classed as a BIG THING on site 1 lane 2 was recorded with a length of
12.01m, a speed of 70kph and a headway of 25.5s or more. The detection invoked
output actions 0, 1, 2, 3 and 15.
NOTE : The above display format assumes all data fields are present in the VC
event. The stored data content of the VC event is configurable so that not all of the
above fields may be displayed by the OLG handset command for a given VC event.
