SAFETY WARNING
HEALTH AND SAFETY AT WORK
DISCONNECT ALL POWER TO THE CABINET BEFORE REMOVING OR
INSTALLING ANY EQUIPMENT INTO THE CABINET.
Safety of Maintenance Personnel
In the interests of health and safety, when using or servicing this equipment the
following instructions must be noted and adhered to:
(i)
Only skilled or instructed personnel with relevant technical knowledge and
experience, who are also familiar with the safety procedures required when
dealing with modern electrical/electronic equipment are to be allowed to use
and/or work on the equipment. All work shall be performed in accordance with
the Electricity at Work Regulations 1989.
(ii) Such personnel must take heed of all relevant notes, cautions and warnings in
this Handbook and any other Document or Handbook associated with the
equipment including, but not restricted to, the following:
(a) The equipment must be correctly connected to the specified incoming
power supply.
(b) The equipment must be disconnected/isolated from the incoming
power supply before removing any protective covers or working on any
part from which the protective covers have been removed.
(c) This equipment contains a Lithium battery that must be disposed of in a
safe manner. If in doubt as to the correct procedure refer to the
Siemens instructions CP No. 526.
(d) Any power tools must be regularly inspected and tested.
(e) Any ladders used must be inspected before use to ensure they are
sound and not damaged.
(f)
When using a ladder, before climbing it, ensure that it is erected
properly and is not liable to collapse or move. If using a ladder near a
carriageway ensure that the area is properly coned and signed.
(g) Any personnel working on site must wear the appropriate protective
clothing, e.g. reflective vests, etc.
In the event of more than one person working on the Controller and its associated
signal heads, the Mains Supply to the Cabinet Assembly must be switched off. If the
master switch has a lock, this should be used to keep the switch locked in the „off‟
position.
667/HB/27880/000
Page 3
Issue 8
ST700 GENERAL HANDBOOK
In countries where both sides of the incoming supply are above earth potential, the
Master Switch or Circuit Breaker on the rear of the Cabinet should be opened, since
the Controller Switch on the front of the ST700 does not isolate both sides of the
supply.
When re-commissioning signals, the following sequence is recommended:
1.
2.
3.
Switch OFF the Cabinet Assembly at the master switch
Switch ON the lamps on-off switch on the manual panel
Switch ON the Cabinet Assembly at the master switch.
More specific safety information is given within the text of the handbook, where it
relates to particular activities or situations.
WARNING
To isolate the equipment the master switch must be in the
“Off” position.
Switching either the Controller or the Manual Panel Signals
On/Off switch to “Off” does not guarantee isolation of the
equipment.
Safety of Road Users
It is important that all personnel are aware of the dangers to road users that could
arise during repair and maintenance of traffic control equipment.
Ensure that the junction area is coned and signed as necessary to warn motorists
and pedestrians of any dangers and to help protect the personnel working on the
site.
Whilst repairing signals which are in an "all-out" condition, care must be taken to
ensure that no spurious signals are lit during testing which could mislead drivers or
pedestrians. Particular care is required where pedestrian audible devices are
installed, to ensure that no false indications are given during, for example, cable
testing. Personnel should also ensure the safety of pedestrians, especially children,
who may come into contact with parts of the ST700 Rack Assembly, Cabinet
Assembly or signal poles.

2. SPECIFICATION
The Specification that follows is for the ST700 Cabinet Assembly. Where appropriate
it also applies to the ST700 Rack Assembly as supplied for installation in another
Cabinet.
Export specifications are detailed where they differ from standard UK specifications.
2.1 EQUIPMENT INTRODUCTION
The ST700 is a Pedestrian Controller and Small Export Traffic Controller.
It can be supplied as
Single Pedestrian controller (2 Phase)
Dual Pedestrian Controller (4 Phase)
Small Export Controller (6 Phase)
When the ST700 is supplied without an outercase it is known as the ST700 Rack
Assembly.
Generally it comes as a fully fitted Cabinet Assembly with its own equipment
mounting frame, mounting stool, mains distribution, power supplies, electronic
control and phase switching. It is then known as the ST700 Cabinet Assembly. This
ST700 Cabinet Assembly can also accommodate Detectors, I/O PCB, OTU PCB, an
OMU Assembly, Manual Panel, Master Switch Assembly and a Dimming
Transformer.
The ST700 Cabinet is ground mounted and small in size, it has front, sides and top
access when the Cabinet lid is removed.
It may also be fitted as a “Cuckoo” into many existing cabinets, when supplied as a
Rack Assembly consisting of the power/phase assembly and a CPU. There are a
number of conversion kits available that enable it to be installed into other cabinets.
The ST700‟s electronics consist of three PCBs:
The CPU PCB that contains most of the logic, which controls the
system and the extra low voltage inputs and outputs, i.e. detector inputs,
audible outputs, etc.
The Phase Drive PCB that contains most of the Mains distributions, the
triac phase drive outputs, voltage and current monitoring.
The PSU (24V) that provides the main power supply for the ST700.
The CPU PCB operates under the control of both a main and a secondary
processor. The main processor is a Motorola 68340, which runs the firmware
controlling all the functions of the ST700‟s operations. The secondary processor is
an Intel 80C31 controlling all the phase output switching and voltage monitoring. The
667/HB/27880/000
Page 13
Issue 8
ST700 GENERAL HANDBOOK
two processors communicate with each other through shared RAM. This dual
processing provides additional safety features, as each processor continually
monitors the actions of the other, and independently turns off the lights to the
motorists and pedestrians if either processor causes an error.
The software is written in a powerful high level language that allows the
implementation of the ST700‟s extensive facilities. The ST700 offers both Single and
Dual Pedestrian operation and up to a 6 Phase Traffic Controller operation, each
with solid state switching.
The power/phase assembly with its associated Phase Drive PCB and PSU can drive
up to 18 signal outputs with 230V at 4A. The pedestrian signals are configurable to
supply either 230V or 48V. Each of the two pedestrian groupings has current
monitoring on two separate vehicle approaches for Red, Amber and Green lamps
plus one unmonitored approach Red lamp only. This provides TR0141C Red lamp
monitoring for the Red lamps and lamp monitoring for the Amber and Green lamps.
It can be supplied as an ST700 Cabinet Assembly or as an ST700 Rack Assembly
ready to be mounted in other cabinets. Mounting in other cabinets requires an
addition conversion kit, and any of the ancillary equipment that may be required i.e.
Detectors, OTU, etc.
2.1.1 Single Pedestrian Controller
The ST700 Single Pedestrian Controller consists of one vehicle phase and one
pedestrian phase with a minimal set of I/O to perform all the functions of 2 phase
Pelican, Puffin or Toucan. These consist of 32 buffered inputs, 8 isolated relay
outputs, 2 Audible outputs and 1 Tactile Interlock output.
Expansion may be achieved by adding combinations of the following equipment:
Inputs/Outputs PCB
This board can expand the inputs/outputs as follows:
16 Inputs
16 Outputs
Detectors
These can be Siemens, Microsense or Sarasota self tuning units. Up to 4 units
can be accommodated in the ST700 cabinet, each unit having four detector
channels.
Ancillary Equipment
OTU – Outstation Transmission Unit for Tele Command 12.
OMU – Outstation Monitoring Unit for Remote Monitoring System.

2.1.2 Dual Pedestrian Controller
The ST700 Dual Pedestrian Controller consists of 2 vehicle phases and 2 pedestrian
phases with a minimal set of I/O to perform all the functions of 4 phase Pelican,
Puffin or Toucan. These consist of 32 buffered inputs, 8 isolated relay outputs, 4
Audible outputs and 2 Tactile Interlock outputs.
2.1.3 Small Export Controller
The ST700 Small Export Controller consists of a 6 Phase Traffic Intersection
Controller. It is similar to the Pedestrian controllers, except in the following areas:
It has 6 Phases
It has no built in current lamp monitoring facilities
It cannot be configured to output 48V from any of its Phase Drive
outputs.
2.1.4 Types of Pedestrian Controller

Frequency:
50Hz 2Hz or
60Hz 2Hz
Mains Brownout:
Continues operating with up to 50mS loss of mains.
Mains Fail:
Restarts without operator intervention.
Battery Support:
Primary cell Lithium battery provides support for the
following during power failures.
(a) Clock Synchronisation (programmable up to 31
days).
(b) Timing Data (greater than one year).
A large capacitor provides support for a minimum of 4
hours if the battery has failed or is removed for
replacement.
Dimming Voltage:
120V, 140V, 160V RMS
Solar Cell Input:
Dimming cannot be provided at mains supplies below
200V.
Solar input operating voltages are as follows:
Bright to Dim > 80V RMS
Dim to Bright < 40V RMS
The solar cell enables the ST700 to identify the light level and thus dim the signals
when it is dark. The switch is set to operate at 55 lux and release at 110 lux. There is
an optional time switch that can be used to regulate dimming control if required.
2.3.1 Electrical Noise
2.3.1.1 Supply Transients
The ST700 has been designed to withstand all the transients as defined in EN50295
on its supply.
2.3.1.2 Electrical Interference
The ST700 has been designed to create very little electrical interference, by the use
of mains filters and solid state lamp switching control. The mains filters protect the
incoming mains supply from any ST700 generated signals. The lamp switches are
switched at zero crossover of the mains supply to reduce any switching transients.
The switching of the signals for dim/bright lamps changeover is controlled carefully to
ensure the inductive switching does not cause interference.
The ST700 design is also extremely tolerant of externally generated electrical
interference. Care is taken to avoid earth loops using a „Star‟ point earthing system
667/HB/27880/000
Page 17
Issue 8
ST700 GENERAL HANDBOOK
to which the cabinet, the internal metalwork, the junction cabling and the mains earth
is connected.
The arrangement and partitioning of the equipment is carefully organised to reduce
electrical noise.
The PCBs have two inner layer planes used for noise reduction. One is connected to
zero voltage and the other connected to +5V, to form a complete screen with
extensive capacitive de-coupling across the planes, which form the logic supplies.
Unused inputs are connected to the logic supplies to ensure their logic state.
The phase switching (signal outputs) system has isolation provided by Opto-SCRs
and zero crossing switched Triacs, for the mains switching. The circuit includes a
snubber filter circuit that aids triac switch off and reduces noise when an inductive
circuit is connected.
2.4 DETERMINATION OF LOADING AND POWER CONSUMPTION
Described below are the methods used to determine:
how the ST700 supplies the total lamp load required
the overall power used and thus estimate site running costs.
2.4.1 ST700 Load
The typical supply requirements for an ST700 are:
40 watts
Single (2 Phase) or Dual (4 Phase) Pedestrian
Controller
50 watts
Export Controller (6 Phase)
2.4 watts per unit
Siemens ST4R detectors
3 watts per unit
Sarasota MTS36Z (2 channel) or MTS38Z (4 channel)
detectors. (NB The power consumption is the same
for both 2 and 4 channel units.)
6 watts per unit
Microsense detectors
These requirements exclude lamp loads, detectors and OTU but include dimming
transformer.

Calculate the total average signal lamp power as follows, using the bright figures in

Total average signal lamp power is the sum of the signal lamp power plus the sum of
the Wait indicator power. Assuming that HI lamps take 63W each, the theoretical
crossing (Figure 1) calculation would be:
One lamp per signal head @ 63W x 12 signal heads

2.4.3 Calculation of an Intersection’s Power Requirements for Running Costs
Estimate
The following worked example is based upon a 230V/240V mains supply.
1. Calculate the total average lamp power for the junction as shown in Table 1.
2. Add the total average signal lamp power to the total average controller power:
Total average controller power is calculated as follows:
667/HB/27880/000
Page 20
Issue 8
ST700 GENERAL HANDBOOK
Average Controller power + Average Detector Power. See section 2.4.1.
A controller is rated at 40 watts (single or dual Pedestrian Controller).
For the purposes of this calculation Siemens ST4R detector cards are rated at 3W
per card.
This gives the total average junction power, which may be used to estimate running
costs.
i.e. Total average junction power
=
Total average signal lamp power +
Total average controller power.
Therefore for our theoretical crossing (Figure 1) the total average controller power is:
1 x Controller
2 x Siemens ST detectors
Total average controller power
40 W
6W
46 W
Table 2 – Calculate Total Average Controller Power
Note:
The controller power should also include any additional equipment supplied
by the controller. This may include, for example, OTU, OMU or Auxiliary
detector power supply.
For the total average junction power to aid with running cost estimates, the total
average lamp power must be added to the total average controller power.
Total average junction power is calculated as follows:
Total average lamp power
Total average controller power
Total average junction power
916 W
46 W
962 W
Table 3 – Calculate Total Average Junction Power
If an estimate of running costs is required that includes the period of time that the
signals are dimmed, this can be approximated as follows:
Total average Junction Power (Dimmed) is:
Total average Signal Power x (Dimmed Voltage / Nominal Mains voltage) plus
Total average Controller Power.
Therefore for the theoretical crossing in Figure 1:
Total average Junction Power (Dimmed)
= (916W x (160V/240V)) + 46W
= 657 W

ST700 GENERAL HANDBOOK
2.4.4 Detector Power Supplies
The maximum current available for detectors on the ST700 is 0.6A at 24V DC. Refer
to the Detector Handbooks for power consumption of detectors.
If more current is required, then power all detectors from a 24V AC Detector PSU.
See Appendix A for part number. This PSU provides a maximum of 2A at 24V AC
and is in the form of a transformer that can be mounted in three different positions:
On the side of the Detector chassis using the four appropriate fixing holes
On the back of the metal outer case frame near the mount position of the
detector chassis, using the four appropriate fixing holes.
On the left-hand side flange of the metal outer case frame just above the
Master Switch Panel, using the four appropriate fixing holes.
2.4.5 Audible and Tactile Supplies
The Audible and Tactile power supplies on the ST700 are designed to provide a DC
voltage between 10V and 24V, and typically provide a maximum of 100mA at 18V
DC.
The ST700 provides three audible outputs on each of the 2 pedestrian phases.
These are located on the CPU card PL2 (Phase D) and PL3 (Phase B).
Pin 11 is titled „Tactile Phase n‟
– This is intended to interlock a tactile unit via
the tactile PSU „interlock‟ input to prevent
operation on a Pelican during the flashing
green man period where the „Loud‟ output
is configured to be time-switched.
Pin 12 is titled „Audible Phase n Loud‟ – This is the normal connections to audibles.
This output can be configured to be timeswitched. If the tactile is also required to
be switched then the tactile PSU „interlock‟
input signal can be taken from this output.
Pin 13 is titled „Audible Phase n Quiet‟ - This output is for the secondary physically
muted audible.
Audible and Tactile units used must operate correctly over the voltage range 10 to
24V DC.
The units recommended and supplied by STCL that meet this requirement are:
Audible:
667/4/04785/000
Highland Electronics type SC628P
(previously Sonalert Mallory SC628P)
Roxborough type SPCI535A4
Tactile:
667/7/17390/000
PELICAN currently Radix RS250 or RS252
667/7/17390/001
INTERSECTION currently Radix RS251 or RS252
667/HB/27880/000
Page 22
Issue 8
ST700 GENERAL HANDBOOK
NOTE – There are four main situations for audible/tactile control that arise on an
ST700. These are –
1. Normal Audibles – The „Loud‟ output is used.
2. Switched Audibles – The „Loud‟ output can be used configured to switch
off at selected times (e.g. at night). If the Tactiles are also to be switched
then the tactile PSU „interlock‟ input can be connected to this output.
3. A Muted Audible Output – The „Quiet‟ output can be connected to the
second audible. This audible will require a local physical muting method.
4. A Pelican With Flashing Green Man – The „Loud‟ output is off during the
flashing period. Thus the „Loud‟ output is used to connect to the audibles
and the tactile PSU „interlock‟ signal input. If the „Loud‟ output is configured
to be time switched, then the „Tactile‟ output is used to control the tactile
PSU interlock signal input.
2.5 PHASES
The ST700 Pedestrian Controller supports either 2 „Real‟ Phases for a single
pedestrian crossing or 4 „Real‟ Phases for a dual pedestrian crossing.
The ST700 Export Controller can support up to 6 „Real‟ Phases.
The ST700 software can support up 32 phases, which can be any combination of
real and software phases.
2.6 STAGES
The ST700 software supports up 32 stages. Note that Stage 0 is normally ALL RED.
2.7 TIMINGS
All ST700 timings are transferred to battery supported RAM during initialisation.
Once in RAM, most timings can be varied by handset commands. Once the
configuration data has been loaded into the ST700, the same configuration cannot
be loaded again. This prevents the accidental overwriting of any configuration data
that may have been set up using the handset.
In the UK some timings considered to be fixed timings cannot be changed by
handset. These are typically the Amber and Red/Amber periods. These timings can,
however, be specified as alterable at configuration time to suit other signal
sequences, export requirements etc.
Some timings considered to be safety timings can only be changed by a person at
the ST700 operating the write enable „level 3‟ push button, e.g. minimum green,
intergreen, blackout timings, etc.
The default timings for the ST700 standard Pedestrian configurations are given in
their IC4 printouts (Special Instructions). These printouts also show the handset
667/HB/27880/000
Page 23
Issue 8
ST700 GENERAL HANDBOOK
commands that are used to change each of the timings. Some of these timings are
described in Section 3.
A summary of all the timings available within the ST700 export intersection controller
is contained in the ST800 General Handbook (see Section 1.3 for details). It also
shows their upper and lower limit values and, where applicable, the configurable
limits.
2.7.1 Tolerance
All timings, except CLF and Master Time Clock, are derived from the crystal
frequency which has a tolerance of 35 parts per million. An additional error, due to
random signals not being synchronised to the clock pulse, may add up to 200ms to
the time.
If the result of the above timings is required to change the signal lamps, a further
error may occur up to a maximum of 21ms.
The set-up accuracy of the real time clock and the accuracy of any offsets calculated
from it will be 1 second.
2.8 MASTER TIME CLOCK AND CLF SUMMARY

3. PEDESTRIAN FACILITIES
3.1 TYPES OF PEDESTRIAN CROSSINGS
3.1.1 Pelican Crossing
The vehicle to pedestrian intergreen is controlled by the PAR Pedestrian All-Red
period. The PAR handset command allows different all-red periods to be executed
depending on why the vehicle phase left green. Different times can be specified for
each of the following: fixed vehicle period mode (see section 3.2.1), VA mode „gap‟
change and VA mode „max‟ change (see section 3.2.2), a „linked‟ change (see
section 3.2.4).
The pedestrian to vehicle intergreen is divided into three fixed periods governed by
the PIT Pelican Intergreen Times.

3.1.2 Near Sided Pedestrian Crossing
The vehicle to pedestrian intergreen on a stand-alone crossing is controlled by PAR.
However if the near-sided pedestrian phase is part of an intersection stream, then
this period is controlled solely by the IGN intergreen command.
The pedestrian to vehicle clearance period consists of:
a minimum period governed by PBT p,
an extendable period limited to a maximum governed by CMX p,
a gap clearance delay CDY p 0, or
a max clearance delay CDY p 1
where „p‟ is the pedestrian phase letter.

On intersections, the appearance of the vehicle phase will be delayed further if the
IGN intergreen time is larger than PBT plus the red/amber period.
3.1.3 Far Sided Pedestrian Crossing
The vehicle to pedestrian intergreen on a stand-alone crossing is controlled by PAR.
However if the far-sided pedestrian phase is part of an intersection stream, then this
period is controlled solely by the IGN intergreen command.
The pedestrian to vehicle blackout clearance period consists of:
a minimum period governed by PBT p,
an extendable period limited to a maximum governed by CMX p,
a gap clearance delay CDY p 0*, or
a max clearance delay CDY p 1
where „p‟ is the pedestrian phase letter.
Following this blackout clearance period, there is a clearance all-red period CRD p.
0 The gap clearance delay CDY p 0 is usually set to zero and hence is not shown
on the following diagram.

On intersections, the appearance of the vehicle phase will be delayed further if the
IGN intergreen time is larger than PBT plus CRD plus the red/amber period whether
CMX is zero or non-zero. But for backwards compatibility, if CMX and CRD are both
zero, then the intergreen is controlled solely by IGN even if PBT is set longer.
3.1.4 On-Crossing Detectors
„On-Crossing Detectors‟ are above ground detectors that are used to determine
whether pedestrians are still crossing. While pedestrians are still crossing, the
extendable clearance period is extended, up to its configured maximum (CMX in the
above diagrams).
The on-crossing detector inputs are configured using a new screen on IC4, similar to
the VA demand/extension screen, and the extension times are configured on an
input basis (i.e. IPX).
If an on-crossing detector is unused, i.e. where several have been configured by
default on a stand-alone controller, it can be de-allocated using IOA. If no extendable
clearance period is required on a particular phase, then the clearance maximum time
(CMX) can be set to zero. If all of the on-crossing detectors for a phase are de-
667/HB/27880/000
Page 31
Issue 8
ST700 GENERAL HANDBOOK
allocated but the clearance maximum time is non-zero, then the clearance period is
extended up to its maximum.
Also note that if the Continuous Ped Demand (CPD) button on the manual is
pressed, then the red clearance of near-sided signals will be extended to its
maximum as required by TR0141C.
If an on-crossing detector has not been activated from the end of the preceding
pedestrian clearance period to the end of the current pedestrian steady green period,
then the clearance period is forced to run to its maximum.
A fault will not be recorded if this occurs, instead the controller will wait until the
normal DFM time-outs confirm and report a fault.
3.2 PEDESTRIAN MODES OF OPERATION
A stand-alone pedestrian crossing can run any of the following modes of operation:
3.2.1 Fixed Vehicle Period
The vehicle phase appears at green for at least a fixed period. No vehicle detection
equipment is required.
If the pedestrian phase is demanded while this period is still running, the vehicle
phase remains at green. When the period expires, the vehicle phase loses right of
way and the pedestrian phase subsequently appears at green.
If the pedestrian phase is demanded after this fixed vehicle period has expired, then
the vehicle phase immediately (subject to the pedestrian demand delay see section
3.3.3) loses right of way and the pedestrian phase subsequently appears at green.
When the pedestrian phase has completed its green period and the controller has
executed the required „pedestrian to vehicle clearance period‟ (see section 3.1), the
vehicle phase returns to green.
The fixed vehicle period is specified by the handset commands MEX, MFX, MGX
and MHX allowing four different times to be called up at different times of the week.
3.2.2 Vehicle Actuated
This mode requires vehicle detection equipment, either inductive loops cut into the
road‟s surface or „above ground‟ detectors (usually microwave detectors) mounted
on the signal poles. Activations on these inputs start (or restart) the „extension time‟
for the phase and while this is active, the vehicle phase will (normally) remain at
green.
667/HB/27880/000
Page 32
Issue 8
ST700 GENERAL HANDBOOK
The vehicle phase appears at green for at least a minimum period specified by the
MIN handset command.
If the pedestrian phase is demanded while this period is still running, the vehicle
phase remains at green until at least this period has expired.
If the pedestrian phase is demanded after this „minimum‟ period has expired and no
vehicles are present, then the vehicle phase loses right of way immediately.
If the vehicle detectors indicate that vehicles are present, then the vehicle phase will
remain at green until the vehicles are no longer present. This is referred to as a „gap
change‟ since the vehicle phase loses right of way to service the pedestrian demand
when a gap in the traffic appears.
However, when the pedestrian phase is demanded, the vehicle phase‟s „maximum
green timer‟ is started. If vehicles continue to be present, keeping the vehicle phase
at green, the vehicle phase will lose right of way when this timer expires, even if
vehicles are still present. This is referred to as a „max change‟ since the vehicle
phase loses right of way when its maximum green time expires.
The maximum green time is specified by the handset commands MAX, MBX, MCX
and MDX allowing four different times to be called up at different times of the week.
When the pedestrian phase has completed its green period and the controller has
executed the required „pedestrian to vehicle clearance period‟ (see section 3.1), the
vehicle phase returns to green.
3.2.3 Vehicle Actuated with Pre-Timed Maximum (PTM)
This mode is very similar to normal vehicle actuated mode, except that the vehicle
phase‟s maximum green timer is started as soon as the vehicle phase appears at
green, regardless of whether there is a demand for the pedestrian phase.
The option is enabled using the PTM handset command.
Therefore, if the vehicle phase has already been at green for longer than its
configured maximum green time when a push-button is pressed, the vehicle phase
loses right of way immediately subject to the pedestrian demand delay (see section
3.3.3) or the pre-timed maximum extra period (see section 3.3.4).
Compare this to the normal vehicle actuated mode, where the pedestrian would have
to wait for up to the maximum green time (if vehicles continue to be present) before
the vehicle phase loses right of way.
667/HB/27880/000
Page 33
Issue 8
ST700 GENERAL HANDBOOK
3.2.4 Linked Operation
With the controller running any of the above three modes, the operation controller
can be further modified by various „linking‟ options.
These options hold the vehicle phase at green until a specific time when the
pedestrian phase is allowed to appear. During this „window‟ vehicle extensions are
removed to ensure that any pending demand for the pedestrian phase is serviced.
This is often required, for example, when the pedestrian controller is close to an
intersection where it is beneficial to keep the pedestrian controller at vehicle green
during certain stages of the intersection controller to help the traffic entering and/or
leaving the nearby intersection.
Cableless Link – Using the controller‟s Master Time Clock and CLF facilities, the
controller can be given one or more „windows‟ during the CLF cycle when it is
allowed to service the pedestrian demands. For the rest of cycle, the vehicle phase
remains at green.
UTC – The „PV‟ control bit from the instation holds the vehicle phase at green. When
the „PV‟ bit is de-activated for a short period, the controller will service any pending
demand for the pedestrian phase.
Local Link – The „PV1‟ input from an adjacent controller holds the vehicle phase at
green. When the „PV1‟ bit is de-activated for a short period, the controller will service
any pending demand for the pedestrian phase.
3.3 PEDESTRIAN DEMAND CONTROL
3.3.1 Introduction
In addition to pedestrian push buttons, the controller can be configured with „kerbside
detectors‟. This allows the controller to cancel the demand (and switch off the wait
indicator) if the pedestrian crosses before the pedestrian phase gains right of way.

3.3.2 Pedestrian Demand Acceptance
If no kerbside detectors are configured, pressing the pushbuttons generates a
latched demand for the pedestrian phase, which is only cleared when the pedestrian
phase gains right of way.
If kerbside detectors are configured, then the operation is as follows:
Every pushbutton input, kerbside input and cycle detector input is configured with its
own extension period specified by the IPX handset command. Each extension period
remains active for the configured IPX period after the input returns to inactive.
When a pushbutton is pressed, the pushbutton extension period is started. Similarly,
when a kerbside detector is operated, the kerbside extension period is started and
when a cycle detector is operated, the cycle extension period is started.
A demand for the pedestrian phase is accepted and the wait indicator illuminated
when a push button extension and a kerbside extension are both active at the same
time. Also, a demand is accepted when a cycle extension and a kerbside extension
are both active.
3.3.3 Pedestrian Demand Delay (PDD)
The transition from vehicle green to pedestrian green starts with the vehicle
changing to amber. As required in, for example, section 6.2.1.1 of TR0141C, a delay
can be configured before starting this transition so that the vehicle phase does not
terminate as soon as the pedestrian push button is pressed, although the wait
indicator is illuminated.
The delay is controlled using the handset command PDD.
The controller uses the following rules:
In VA mode, if one or more real phases are at ROW and none of the
phases at ROW have pre-timed maximums configured, then the delay is
not applied, since if vehicles are present, their extensions keep the vehicle
phase at green.
In VA mode, the controller examines the maximum green timers of all
conflicting phases which are at ROW which are also configured to run pretimed maximums (but see section 3.3.4). If any have expired or have less
time to run than the delay, then the delay is introduced, otherwise all have
more time to run than the delay, so no delay is introduced and the
controller will only allow the stage change if none of the phases are being
extended.
In VA mode, if no real phases in the same stream are at right of way, then
the delay is introduced, so delaying the appearance of the pedestrian green
after an all-red period.
In all other modes, the delay is always introduced. This is to cater for cases
such as „fixed vehicle period‟ mode, UTC inserting a demand dependant
667/HB/27880/000
Page 36
Issue 8
ST700 GENERAL HANDBOOK
force for the pedestrian phase or CLF introducing a demand dependant
move just after the push-button is pressed. Introducing the delay prevents
these cases making a stage move shortly after the push-button is pressed.
In most other cases, the demand delay has little or no effect.
Note that special conditioning can always be written to „short-circuit‟ the pedestrian
demand delay if required under certain circumstances by putting in an unlatched
demand for the phase if the wait indicator is lit.
3.3.4 Pre-Timed Maximum Extra Period (PTX)
There is alternative facility to delay the termination of the vehicle phase for use with
the vehicle actuated pre-timed maximum facility described in section 3.2.3.
If the pedestrian phase is demanded after the pre-timed maximum period has
expired (or is close to expiring) the maximum green timer is re-started with a short
„extra‟ time period specified by the PTX handset command. Therefore, if vehicles are
still present, the vehicle phase remains at green for up to this time. If no vehicles are
present the vehicle phase loses right of way as soon as the push button is pressed
(unlike PDD, which always applies its delay).
3.3.5 Pedestrian Demand Cancel (PDX)
The phase demand is cleared and the wait indicator is extinguished when all
kerbside detectors and their extensions for the phase have been inactive for the
configured pedestrian demand extension time for the phase (PDX). Note that the
phase may still appear at green if the controller has already started the move to the
stage in which the phase appears.
3.3.6 Kerbside Detector (Mat) Testing
Kerbside detector testing can be performed by the firmware to check the operation of
kerbside „mat‟ detectors.
Every 60 seconds, if there are no pedestrian phase demands active and no pushbutton (or cycle) inputs active, the controller outputs a 500ms (±50ms) test pulse on
a configured output. If the output is de-allocated using IOA, then no kerbside testing
will be performed.
This output is connected to all the kerbside detectors and should result in all of the
kerbside inputs going active during the pulse.
Therefore, the test is not performed while a pedestrian demand exists since this will
extend the pedestrian demand if the kerbside input has just gone inactive and the
controller is timing off the kerbside and demand extension periods.
Nor is the test performed while any push-button or cycle inputs (or their extensions)
are active since the kerbside test will activate the kerbside inputs even though no667/HB/27880/000
Page 37
Issue 8
ST700 GENERAL HANDBOOK
one may be present and allow these inputs to produce a demand for the pedestrian
phase.
Each configured kerbside detector is sampled twice and if either sample on a
particular kerbside detector indicates the detector is inactive1, then the detector is
logged as faulty, the DFM indicator is illuminated and the detector input forced active
(regardless of the setting of the DFM forcing action command „DFA‟).
Thereafter, the force is only removed after 5 consecutive tests of the detector have
passed, but the fault log entry remains set and the DFM indicator remains
illuminated, until RFL=1 is entered (as required by TR0141C).
This facility uses the normal DFM fault log flag (FLF 12) and fault log data (FLD 20 to
31) but will be clearly distinguishable in the historic rolling log. If a kerbside detector
fails its tests, a fault is logged in the FLF/FLD fault log and in the rolling log as „DFM
L? KERBF‟. If it subsequently passes the kerbside test five times, then „DFM L?
KERBP‟ is recorded. No more entries against this input will be recorded in the rolling
log until the fault log is cleared using RFL=1 and „DFM L? KERBC‟ is recorded.
If it also fails the normal DFM check some time later, then the FLF/FLD fault log
entries will not change, but a normal DFM entry such as „DFM L95 IN12H‟ will be
added to the rolling log at this new time.
If ADF=1 is entered to accept DFM faults, then if either type of DFM fault has been
logged against a kerbside detector, then this detector is accepted as being faulty and
no longer goes towards illuminating the DFM indicator. The DFM indicator will not
illuminate again if the other DFM test subsequently fails.
If the maintenance engineer enters RFL=1, the controller automatically performs a
test. If a kerbside detector which was reported as faulty passes this test, even if this
is the first test that it has passed, the fault log entry for that detector is cleared and
the detector is assumed to be working. This means that when the maintenance
engineer fixes a kerbside detector, they do not have to wait for 5 automatic tests
before they can clear the fault, they just need to enter RFL=1.
If a kerbside detector input is de-allocated using IOA, the test is assumed to have
passed. This caters for the case where an unused kerbside detector input fails the
test, before the engineer sets IOA to 255 to de-allocate the input and then enters
RFL=1 to clear the fault.
However, if the detector has failed normal DFM time-out stuck active or inactive,
then it also needs a change of state of that input before the fault is cleared. Note that
a detector that has failed stuck active naturally passes the kerbside detector test so
this additional check is still required.
1
Note that for the input to be seen inactive at the 200ms processing rate, all ten
20ms samples must have been inactive.

Figure 4 – ST700 Rack Assembly
The ST700 Rack Assembly consists of a box like frame with a plate hinge on the
front that acts as an access door.
The Phase Drive PCB is mounted behind the ST700 CPU PCB in the Cabinet. This
contains the logic power supply, the mains distribution, Solid State Relay, A Relay, B
Relay, Dimming relays, the mains fusing, and the Phase Drives, along with the
terminal blocks to wire the phase drives directly to the road side cables. The Phase
Drive PCB has a flying 64-way Phase Control Bus ribbon cable attached. This
connects to the ST700 CPU PCB and supplies the power and control signal to that
card.
Mounted on the heatsink cover of the Phase Drive PCB is the mains power supply
unit (24V DC output) that is mains powered from, and supplies 24Volts to, the Phase
Drive PCB via a cableform.
The ST700 CPU PCB is mounted on the outside of the hinged plate. This contains
the Dual Processors and associated logic, LED signals and status visual display,
Handset Port, Modem Port, Manual Panel Port and I/O circuits along with the
terminal blocks to wire the I/O circuits directly to the road side cables.
667/HB/27880/000

ST700 GENERAL HANDBOOK
This leaves space on the inside of the hinged plate to mount an additional I/O PCB
or OTU PCB as and when required. These cards are the same as those used on the
ST800 and thus are connected to the ST700 CPU PCB using an extended system
bus cable that runs along the side.
A pictorial view of the ST700 CPU PCB and Phase Drive PCB is given in Figure 4.
The photograph in Figure 5 shows the ST700 Rack Assembly mounted in an ST700

The top Status LED is green and is labelled „PP‟ for power present. This LED flashes
giving a heartbeat indication that the ST700 is running normally.
If it does not illuminate there is no power to the CPU PCB. Check that the ST700 is
powered and that the Phase Control ribbon cable is inserted into the socket of the
CPU PCB.
The other two LEDs are red and identify various fault conditions.
The top red LED is labelled „SE‟ for system error. This illuminates during the powerup sequence and then extinguishes when the ST700 is running normally with no
faults present in its fault log.
The bottom red LED is labelled „WD‟ for watchdog. This LED is illuminated when the
hardware watchdog circuit times-out. Note that when the firmware detects a serious
fault, it extinguishes the signals and deliberately stops „kicking‟ the hardware
watchdog so that it times-out and reinforces the signals‟ Off or Fail Flashing

4.2.2 Signal LED Group
These LEDs are in groups of three, one for each traffic phase A to F. Each group
has a red at the top, amber in the middle and green at the bottom (see View of
Phase „F‟ in Figure 6) to represent a set of traffic lights. They provide visual
representation of the state of the red, amber and green drives for their respective
phase.
4.3 FUSES
Figure 23 on page 98 lists the types and placing of fuses in the ST700. Fuses should
only be replaced by ones of a similar rating and type.
4.4 DETECTOR CHASSIS AND PSU
The Detector Chassis is fitted at the top right hand side of the ST700 Cabinet frame;
see Figure 5 for the exact position. This Detector chassis can be powered from the
ST700 for up to 600ma at 24V.
If more detector power is required as for AGD units, then all detectors must be
powered by an AC Detector PSU (24) Kit (see Appendix A for the part number). This
Kit provides a maximum of 2A at 24V AC and can be mounted in one of three
positions, depending on the existing equipment in the cabinet. The positions are
detailed in Section 2.4.4 and on the AC Detector PSU (24V) kit drawing (see Section
1.3 for details).

5. INSTALLATION AND COMMISSIONING PROCEDURE FOR THE ST700
The majority of this section details the procedure for installing and commissioning
the ST700 Rack Assembly in an ST700 Cabinet Assembly.
Refer to section 5.19 for instructions on installing and commissioning the ST700
Rack Assembly into other traffic controller cabinets.
5.1 PRE-INSTALLATION CHECKS
The following checks should be carried out at the depot and again at the roadside,
with the exception of the pre-installation self-test which can only be carried out at the
depot.
The Cabinet Assembly should be visually inspected to check for any damage that
may have occurred in transit, e.g. cabinet damage, dents and scratches. Check the
security of all internal wiring and board fixings, including all nuts and screws.
HARDWARE CHECK
Check against the Works Specification that:
-
The correct boards and kit (including the Firmware PROMs and PLD) have been
supplied and fitted correctly.
-
The appropriate links have been made on the boards.
-
All fuses and dummy fuses are fitted and are of the correct ratings.
-
The correct interconnection cabling has been installed within the Cabinet
Assembly, e.g. Detectors to Rack Assembly, OTU to Rack Assembly, etc.
-
The dimming transformer (if fitted) tapings have been set to the correct voltages.
Once the hardware has been checked as above, it is recommended that a self-test is
run (see section 7) before leaving the depot.
5.2 ST700 CABINET ASSEMBLY PREPARATION
Cabinet Assemblies are normally delivered from the factory in a fully assembled and
tested state. However to aid installation, the internal equipment has been designed
to be readily removable.
The cabinet Lid (also known as the case or the sleeve) is attached to the equipment
mounting frame with a screwlock situated inside the manual panel door.
667/HB/27880/000
Page 44
Issue 8
ST700 GENERAL HANDBOOK
5.3 SITE SUITABILITY
The ST700 Cabinet Assembly is installed to suit local conditions, but subject to the
following limitations:
(i)
The position of the Cabinet Assembly is as shown on the relevant site plan,
STS.
(ii)
No part of the Cabinet is less than 457mm (18 inches) from the kerbside
unless agreed with the customer.
When it is necessary to site the Cabinet less than 2 metres from the outer
edge of the kerb, the access panels should not open toward the carriageway.
Where no pedestrian guard rails are fitted, a clearance of at least 600mm
should be left between the Cabinet and the kerb edge so that guard rails may
be installed at a later date without the need to disturb the Cabinet installation.
(iii)
Removal of the Cabinet Lid should be easily achieved without extending the
Lid over the roadway or obstructing the footpath when removed. The
dimensions of the Lid are 982mm x 375mm x 255mm. To remove it from the
equipment mounting frame, it needs to be lifted up until it clears the inside
Assembly, and then rested on top of the equipment mounting frame. This
allows the Lid‟s Faston connector on the earth lead to be removed from the
Faston Tag on the side flange (on Manual Panel side) of the ST700 Cabinet
Assembly. The Lid is then free from the ST700 Cabinet Assembly. It must be
stored in a suitable place so that it is not a danger to the general public and
set down carefully to prevent scratching. The Earth Lead is permanently
attached to a stud within the Lid with its flying end terminated with a Faston
Tag.
(iv)
Any person having control over the junction, whether manual control or test
box simulation, MUST have a good view of the intersection.
(v)
When the ST700 Cabinet Assembly is to be located on unmade ground (e.g.
a grass verge) it is recommended that paving slabs or a concrete standing be
provided at ground level on the manual panel (left) side and the front side.
The hard standing shall extend a minimum distance of 900mm away from the
door, extending the full width of the Cabinet Assembly, and at least 800mm
away from the side of the cabinet with a flap, again extending the full width of
that side. Customers may specify particular requirements.
667/HB/27880/000

Issue 8
ST700 GENERAL HANDBOOK
5.4 RECOMMENDED ORDER OF INSTALLATION
The following list details the order in which it is recommended that an ST700
installation take place.
Remove the Lid – section 5.5
Remove the equipment mounting frame from the stool – section 5.6
Install the stool into the ground – section 5.7
Pull the cables into position – section 5.8
Terminate the armour to the CET connectors – section 5.8
Fit the CET connectors to the CET bars – section 5.8
Test the cables – section 5.9
In-fill the stool and seal the base – sections 5.10 and 5.11
Fit the equipment mounting frame – section 5.12
Terminate the cables – section 5.13
Check PCB links, switches and firmware – section 5.15
Refit the Lid – section 5.18.
Details of each of the actions are given in the following sections.
5.5 REMOVE THE LID
Remove the Lid from the ST700 Cabinet Assembly as detailed in section 5.3.
5.6 REMOVE THE EQUIPMENT MOUNTING FRAME FROM THE STOOL
Leaving the electronics in the equipment mounting frame, remove the stool by
removing its four fixing screws (the nuts are captured on the stool) and lift the rest of
the assembly off the stool.
The ST700 Cabinet Assembly in its sub-assembled state (in three pieces – the Lid,
the stool and the equipment mounting frame) is now ready for installation.
5.7 INSTALL THE STOOL
A hole should be dug and a flagstone at least 600mm x 600mm embedded securely
at the bottom of the hole. Refer to Figure 7 for the general method of installation and
dimensions. Ensure that enough clearance is left around the stool to enable the
correct fitting of the equipment mounting frame and Lid.
If the ST700 Cabinet is being installed on a slope, allowance must be made for
ground level clearance of the Lid to the uphill side.
667/HB/27880/000
Page 46
Issue 8
ST700 GENERAL HANDBOOK
The stool is placed in the centre of the flagstone with the top surface between 50 and
75 mm above the final ground level. It is essential that the stool be fitted the
correct way round with the single centre edge holes to the front and the CET
fixing holes on the right, as shown in Figure 7. Adjustment may be required to
ensure that the top of the stool is horizontal; this should be checked using a spirit
level.
Mix up a stiff mixture of concrete (mix: 1 cement, 3 sand, 4 coarse aggregate
(20mm) with no excess water) and cover the flagstone to a height approximately
100mm (4”) above the bottom of the stool. The concrete must be sloped to provide a
run up for the cables. Any cables that already enter the pit must be held away from
the wet concrete. Where there is a risk of freezing, a suitable antifreeze additive
should be incorporated in the concrete mix to ensure proper curing.

5.8 CABLING TO THE ST700 CABINET ASSEMBLY
All cables into the ST700 Cabinet Assembly should be fed into the equipment
mounting frame as close to their termination positions as possible. This is to prevent
unnecessary damage being caused should any cables need to be moved once they
are in place. Care must be taken not to obstruct the Electricity Supply Company cutout with any cabling.
The outer sheathing must be stripped to expose the armouring. It is suggested that
between 55mm and 65mm of the inner sheathing is left above the Hose Clip and
stripped armour (see Figure 8), which is more than normally required for other
Cabinet Assemblies. This is due to the height of the CET bar and its staggered fixing
nature. The additional height ensures that double insulation is provided where the
cable rests against the metal items. Sufficient further conductor length must also be
allowed to reach the terminal blocks via the proper routing.
The cable is inserted in the CET ring and the armoured wires are bent outwards and
down against the ring. A hose clip is then placed over the armoured wires and
tightened up. The armouring must be stripped, leaving a small amount (approx. 0 to
2mm) below the level of the CET ring.
The inner sheathing is removed to expose the individual leads that are connected to
associated terminals, leaving sufficient spare length for re-making off the ends
should this become necessary. Unused leads should be left with sufficient length to
enable them to be connected to any terminal should this subsequently become
necessary.
The ST700 can be fitted with up to 3 CET bar kits.
The CET bars are mounted directly on the stool, which has three positions onto
which these bars can be fitted. Each bar has 8 holes for fixing cables; 4 upper and 4
lower fixing positions. This allows the CET rings and hose clips to overlap each
other. Up to 24 cables can be fitted in the ST700 cabinet. Refer to drawing
667/GA/27845/000 for further details of fixing.
When the detector loop tails have been terminated the connection to the detector
backplane must be made with wires twisted together as pairs. Ensure that individual
pairs connect only to the same detector.
See also the Detector Information Handbook.
Cables must be identified as to their destinations. Additional Idents may be required
on specific contracts.

When all the cables have been terminated onto the CET bar they should be checked
and tested as defined in the General Testing handbook.

ST700 GENERAL HANDBOOK
5.10 IN-FILL THE STOOL
On completion of the cable tests the Cabinet Assembly can be in-filled as per Figure
7, taking care that the compacted sand is at ground level when finished.
If any of the cables were replaced or moved during the installation of the Cabinet
Assembly then the sand in-filling must be made good before the sealing compound is
introduced.
NOTE: The in-filling must be brought to ground level or above and compacted and a
tarmac surface provided over the in-fill.
5.11 SEAL THE BASE
To prevent condensation in the Cabinet Assembly the equipment mounting frame
base must be sealed as soon as possible after the ST700 has been installed.
The sealant should be poured all around the cables and to a height which, when the
sealant is set, gives a total covering not less than 6.5mm thick over the base of the
Cabinet Assembly. This is to prevent the ingress of moisture.
Approx. 2.0Kg of Robnorganic PX212ZF or similar base seal epoxy should be
adequate.
A concrete fillet around the outside of the stool may be completed before or after the
epoxy sealing to suit site conditions.
Refer to Figure 7 for general method of in-fill, sealing and concrete fillet.
5.12 FIT THE EQUIPMENT MOUNTING FRAME TO THE STOOL
If the equipment mounting frame was not installed with the mounting stool then it
should be done as follows:
Clean the top surface of the stool and the lower surface of the equipment mounting
frame that will be in contact when the equipment mounting frame is fitted. Apply a
spot of sealant compound to each of the front and rear left hand corners (Manual
Panel side) of the equipment mounting frame.
The equipment mounting frame is installed by lowering it onto the stool and fitting the
four retaining bolts.
When fitting the equipment mounting frame onto the stool, make sure that all the
cables are in their correct position with regard to the CET bar. Once the equipment
mounting frame has been secured, moving cables could cause damage.

ST700 GENERAL HANDBOOK
5.13 CABLE ROUTING & TERMINATION
The following guidelines apply when the ST700 Rack Assembly is installed in the
ST700 Cabinet Assembly or any other controller cabinet.
All intersection cables and their wires must be run up the inside back right hand
corner of the ST700 equipment mounting frame and secured to it with tywraps. This
is the cable/wire position to mount any external current monitoring coils. The
preferred route for the detector cables and their wires is to run over the top of the
dimming transformer (if fitted) and up the left hand side of the ST700 equipment
mounting frame and then over the top of the ST700 Rack Assembly (see the
following note). Although the right hand side can be used if there is sufficient room.
Note: No wire runs or looms should be positioned directly above the ST700 Rack
Assembly, as this would prevent its removal for maintenance or replacement. In the
back of the metal frame across the top of the ST700 Rack Assembly, securing holes
are provided to secure the detector wire looms. These holes ensure that there is
sufficient room to allow the removal of the ST700 Rack Assembly.
Wiring runs should be made neatly and routed to allow enough spare cables for
possible changes/additions at a later date.
Spare cores are to be bundled and routed to a convenient position clear of mains.
The ends are to be insulated to make the loom secured. Spare cores of ELV cables
are to be loomed separately from the cores of LV cables. Note: Normally spare
cores are earthed at the end furthest from the Rack Assembly.
If cable idents are required then these are fitted to cores before termination.
Signal and Detector terminations to the ST700 Rack Assembly should be as per
the Works Specification, leaving sufficient spare wire to enable joints to be remade
when necessary. The „Pair‟ cable used for connection from the loops should be
terminated using the appropriate kit.
OMU must monitor the Controller Lamp Supply at the screw terminal on SK2 Pin
6.
Note: The following connectors‟ identification, signal allocation, coding information
(when required) and Softwire colours (when used) are given as guidance to assist
the installation engineer, when wiring to the Works Specification. No Softwire Kit is
required to wire an ST700 Rack Assembly into an ST700 Cabinet as the Intersection
Cables can be wired directly to the ST700 terminals. Softwire Kits are available to
install an ST700 in other Cabinets. If the Softwire kit is used in the ST700 cabinet
assembly, then their associated terminal blocks are mounted on the right hand side
and back of the cabinet‟s inner metal frame. The position of these terminal blocks
means that a short screwdriver (No1 Pozidriv) is required to terminate the wires due
to the proximity of the dimming transformer (if fitted). If there are many cables,
access to the terminal blocks becomes restricted.

5.13.1 Phase Drive PCB Terminal blocks
For installation in an ST700 Cabinet, wire the intersection cables directly to the
specified connector in the following tables (using the respective mating half
contained in the attached plastic bag) on the Phase Drive PCB.
The connectors must be wired as follows:
Ensure 10mm of wire insulation is stripped back
Make sure that the connector is fully undone (open) before inserting the stripped
wire end
Insert the stripped wire end fully to the back stop
Firmly tighten the connector‟s terminal screw ensuring that the wire‟s conductor is
firmly positioned correctly in the connector
Warning: The above method must be used. Failure to do so could result in
the wires coming loose or falling out over a short period of time.
For installation in another cabinet, a Softwire Kit is required. Wire the loose ends of
the Softwire kit Cableform to the cabinet terminal blocks. Use the relevant signals as
defined by the works specification and shown in the tables that follow. Figure 9 also
provides further information on PL6, PL7 and PL8.

Instead of driving all the signals at the 230V nominal supply, the ST700 is capable of
driving the Wait indicators or all the pedestrian phase signals directly with an ELV
48V lamp supply.
Switching the supply from 230V to 48V requires fuses and links on the lamp switch
card to be re-arranged as detailed in Section 5.15. The required arrangement also
667/HB/27880/000
Page 60
Issue 8
ST700 GENERAL HANDBOOK
needs to be configured (using the ELV handset command) and affects what sensors
34 and 38 (or 36 and 40 on the second stream) can monitor. See the following table:
ELV:0 – All signals at
230v
34/36 – Monitor
Red+Green+Wait
(all cables thro‟ torroid
twice)
38/40 – Not Required.
ELV:1 – Waits at 48v
34/36 – Monitor
Red+Green+Wait *1
(Red & Green thro‟ torroid
twice)
(Wait cables thro‟ torroid
once)
38/40 – Can be used to
monitor Wait
(Wait cables thro‟ torroid
once)
ELV:2 – All ped signals at
48v
34/36 – Monitor
Red+Green+Wait *2
(all cables thro‟ torroid
once)
38/40 – Can be used to
monitor Wait
(all cables thro‟ torroid
once)
Sensors 34 and 36 can be used to monitor the Wait Indicators as well as the
Red+Green signals as long as the total current seen by the torroid when the Red
Man and Wait signals are illuminated is less than 4 Amps, otherwise sensors 38 and
40 must be used to monitor the Waits separately.
*1 (ELV:1) Since the Red and Green cables go through the torroid twice, the current
seen by the torroid for those aspects is doubled, so for example:
2x 50W Red Man Halogens (at 230V)
= 2 x 0.22A = 0.44A
2x 40W Wait Indicators (at 48V)
= 2 x 0.83A = 1.67A
} 2 x 0.44 + 1.67 = 2.55A < 4.00A
} So sensor 34/36 can monitor Red+Green+Wait.
2x 50W Red Man Halogens (at 230V)
= 2 x 0.22A = 0.44A
4x 40W Wait Indicators (at 48V)
= 4 x 0.83A = 3.33A
} 2 x 0.44 + 3.33 = 4.21A > 4.00A
} So monitor Waits with sensor 38/40.
Also note that the load displayed for sensors 34 and 36 while monitoring „Red+Wait‟
will be higher than expected as the current taken by the 48V Wait is much larger
than the current taken by the 230V reds.
*2 (ELV:2) Since all the cables only go through the torroid once when being driven at
48V, the calculations are simpler:
2x 20W Near Side Reds (at 48V)
= 2 x 0.42A = 0.83A
2x 40W Wait Indicators (at 48V)
= 2 x 0.83A = 1.67A
} 0.83 + 1.67 = 2.50A < 4.00A
} So sensor 34/36 can monitor Red+Green+Wait.
4x 20W Near Side Reds (at 48v)
= 4 x 0.42A = 1.67A
4x 40W Wait Indicators (at 48v)
= 4 x 0.83A = 3.33A
} 1.67 + 3.33 = 5.00A > 4.00A
} So monitor Waits with sensor 38/40.

ST700 GENERAL HANDBOOK
Note however that at the time of writing, the controller is unable to monitor the
current waveform generated by the low power near-sided signals currently on the
market.
Wiring of external torroids
All drive cables supplying signals at 230V should be wound around the torroid so the
cable passes through the centre twice. (N.B. This includes vehicle aspects as well as
pedestrian aspects.)
All drive cables supplying signals at 48V should only pass through the centre of the
torroid once.
5.13.2 ST700 CPU PCB Terminal Blocks
When installing in an ST700 cabinet, wire the intersection cables directly to the
specified connector in the following tables (using the respective mating half
contained in the attached plastic bag) on the ST700 CPU PCB.
The connectors must be wired as follows:
Ensure 9mm of wire insulation is stripped back
Make sure that the connector is fully undone (open) before inserting the stripped
wire end
Insert the stripped wire end fully to the back stop
Firmly tighten the connector‟s terminal screw ensuring that the wire‟s conductor is
firmly positioned correctly in the connector
Warning: The above method must be used. Failure to do so could result in
the wires coming loose or falling out over a short period of time.
Also, the connectors PL2, PL3, PL6 and PL7 require a small-ended
(2.5mm) screwdriver. Use a Phoenix Screwdriver Part Number SZS
0.4 x 2,5 or equivalent (see note at the top of each table).
When installing in any other cabinet, a Softwire kit is required. Wire the loose wire
ends of the Softwire kit cableform to the terminal blocks in the cabinet, using the
relevant signals as defined by the works specification and shown in the tables that
follow:
Table 13 – Processor Card PL3 Connector
Note: These terminals must be tightened correctly, using Phoenix Screwdriver Part
Number SZS 0.4 x 2,5 or equivalent.

5.14 REGULATORY SIGNS MONITORING
The ST700 Rack Assembly does not cover regulatory signs and their associated
monitoring. There is a fuse position labelled „F3 Detector‟ which could be used to
supply regulatory signs if required. Their monitoring would require standard current
coils to be connected to the external analogue inputs.

5.15.2.1 Fuse/Dummy Fuse Settings
The output voltage for the Pedestrian Red and Pedestrian Green can be set to either
230V or 48V operation. Fitting the fuse and dummy fuse as follows sets the voltage:
For 230V operation fit the 10A fuse in F10 and the dummy fuse in F11.
For 48V operation fit the 10A fuse in F11 and the dummy fuse in F10.
The output voltage for the Pedestrian Waits can be set to either 230V or 48V
operation. Fitting the fuse and dummy fuse as follows sets the voltage:
For 230V operation fit the 10A fuse in F8 and the dummy fuse in F6.
For 48V operation fit the 10A fuse in F6 and the dummy fuse in F8.
Note: The dummy fuse is a plastic spacer, the same size as the fuse it replaces. It is
used to prevent service personnel inserting an extra fuse and thus causing damage
to occur to the ST700.
5.15.2.2 Blue and Red Handbag Links Settings
The output voltage monitoring circuits for the Pedestrian Red and Pedestrian Green
can be set to monitor either 230V or 48V. Inserting the correct coloured handbag
links on the board sets the voltages for the Monitoring circuit. The positions and
colours are as follows:
For 230V operation fit only a Red Link in position LK22 (large pitch).
For 48V operation fit only Blue Links in positions LK22 (small pitch), LK15 and
LK17. On 4 phase units fit LK18 and LK20.
Note: Links LK15, LK17, LK18 and LK20 are accessed through the two rectangular
cut outs in the heatsink cover. See Figure 20 for details. A pair of long nose pliers is
required to insert and extract the handbag links.
The output voltage monitoring circuits for the Pedestrian Wait can be set to monitor
either 230V or 48V. Inserting the correct coloured handbag links on the board sets
the voltages for the Monitoring circuit. The positions and colours are as follows:
For 230V operation fit only a Red Link in position LK21 (large pitch).
For 48V operation fit only Blue Links in positions LK21 (small pitch), LK16 and
LK19.
Note: Links LK16 and LK19 are accessed through the two rectangular cut outs in
the heatsink cover. See Figure 20 for details. A pair of long nose pliers is required to
insert and extract the handbag links. Both the Red and Blue links are wire shorting

links in the form of a handbag, with a handle to aid insertion and extraction. They fit
into PCB mounted sockets and use spring clips in the socket to make the connection
and fit. These spring clips also retain the link to the PCB; the contacts are gold
plated for low resistance and reliability.
5.15.2.3 Links LK1, LK2, LK3 and LK4 Settings

5.16 ON-SITE ST700 TESTING
Connect a suitable handset to the 25-way D-type connector on the ST700 Phase
Drive PCB.
Replace each of the 4 off 10A fuses in the fuse holders F6 to F11 on the Phase
Drive PCB with 3.15A fuses, leaving the dummy fuses in place. See Figure 23 and
Figure 20 for details. This protects the individual circuits whilst the self-test is being
performed in the event of a short circuit in any of the cables.
Select and run the self-test – see section 7.
If the self test passes, replace the 10A fuses in the Phase Drive PCB.
The ST700P stand-alone pedestrian controllers normally run one of the standard
configurations generated by Siemens Poole that are listed below:
EM60700 Stand-alone Pelican crossing with MCE0125 style flashing green man /
flashing vehicle amber.
EM60701 Stand-alone crossing with a red clearance period, i.e. TR0141C nearsided Puffin or Toucan crossing.
EM60702 Stand-alone crossing with a blackout clearance period, i.e. TR0141C
far-sided Pedestrian, Puffin or Toucan crossing.
667/HB/27880/000
Page 73
Issue 8
ST700 GENERAL HANDBOOK
These configurations are available on the IC4 CD. Other configurations may be
produced by Siemens Poole in order to meet the particular requirements of an area
or of one particular site.
These configurations need to be customised for particular installations using the
handset in a similar way to the T400 Pelican, using the information in the special
instructions of the configuration printout.
The commands to customise the ST700 are described in the Handset Handbook and
in the Special Instructions. These allow facilities such as kerbside and on-crossing
detectors and speed discrimination/assessment to be enabled or disabled. However,
the fundamental lamp sequence (i.e. flashing green-man, red-man or blackout
clearance periods) cannot be changed using the handset and is fixed in each of the
default configurations.
The configuration data for a stand-alone pedestrian crossing ST700 is loaded
through the handset port from a PC running IC4.
The configuration data could be loaded while the ST700 is still in the depot rather
than using a PC on the street. Provided the battery isolators are removed, the
configuration data will still be present in the battery backed-up RAM when the ST700
is installed.
The procedure for loading the configuration data is given in the Handset Handbook.
Once the configuration data has been loaded, ensure the Signals ON/OFF switch on
the manual panel is in the off position and connect a suitable handset to the 25-way
D-type connector on the ST700 CPU PCB.
With all signals covered (bagged), use the LMP handset command, which causes
each colour on each phase to illuminate in turn, whilst other persons are checking
the aspects. Care must be taken to ensure that any traffic on the junction does not
mis-read the signals and cause an accident. In addition, a visual check of the wiring
must be carried out, to ensure that the individual approaches are wired correctly as
shown in Figure 9.
The ST700 signals can now be switched on (using the switch on the manual panel)
and the ST700 powered up normally.
If the solar cell and signal dimming are not required then the following test can be
ignored.
1. Cover the photoelectric cell for at least one minute to exclude any light and
check that the signals are dimmed.
2. Remove the cover from the photoelectric cell and after at least one minute
the signals should revert to the bright condition.
667/HB/27880/000
Page 74

ST700 GENERAL HANDBOOK
If detectors are installed then they should be set up as defined in the Detector
Information Handbook.
Set up the date and time.
Check that the Lamp Monitor has correctly learnt all the lamp loads, using the KML
and KEL handset commands, described in the Controller Handset Handbook.
Check that there are no unexplained errors in the fault log.
This completes the testing and the site should be ready for Customer acceptance.
5.17 ST700 START-UP SEQUENCE
When the ST700 is initially powered up, it performs various internal checks before
starting normal operation. While these checks are being performed the green
heartbeat LED flickers and the red system error LED remains on.
If these tests fail then there is a serious fault on the CPU PCB and the PCB should
be replaced. The error message is repeatedly written to the handset display at 1200
baud, and no other handset operations can take place:
RAM FAULT
for RAM read/write test fail
DPR RAM FAULT
for RAM read/write test fail (Dual Port RAM)
PRG PROM FAULT
for program PROM fail
XTL FAULT
for CPU and RTC crystal check fail
In addition to the above internal checks, the ST700 goes on to check the contents of
its battery backed RAM, e.g. the fault log and checksum on the timings data, before
attempting to switch on the signals.
Once the ST700 is running normally, it extinguishes the red system error LED and
the green heartbeat LED flashes.
If the red system error LED remains illuminated then a handset should be connected
and the fault log checked to see what errors exist. The fault log is described in the
Handset Handbook.
5.18 REFITTING THE LID
Reconnect the earth lead by fitting the Faston connector to the Faston Tag. Replace
the Lid carefully on the equipment mounting frame and secure the Lid to the frame
using the „T‟ key.
667/HB/27880/000

Issue 8
ST700 GENERAL HANDBOOK
5.19 FITTING THE ST700 RACK ASSEMBLY INTO ALTERNATIVE CABINETS
DISCONNECT ALL POWER TO THE CABINET BEFORE REMOVING OR
INSTALLING ANY EQUIPMENT INTO THE CABINET.
The ST700 Rack Assembly may be fitted into enclosures other than the ST700
Cabinet Assembly. In the UK, the Cabinet must be one that has previously been
approved with a different controller. Some examples are:
ST800
T200
T400S
T400L
GEC110/125
CST – McQue
T110
T500P
GEC125 in 25 Case
Microsense Midi
The procedure for each type of Cabinet depends largely on the type and condition of
the existing equipment. For this reason it is not possible to define in detail exactly
what should be undertaken, but generally the procedure follows that defined in
sections 5.1 to 5.16.
For some Cabinets, conversion kits of parts are available. These provide brackets
and other equipment that may be helpful during the installation. Part numbers for the
spares available at the time of issue of this handbook are listed in Appendix A.

6. ROUTINE MAINTENANCE PROCEDURES
This section contains a list of checks to be performed at an ST700 on a regular basis
(normally annually).
If for any reason, the power is switched off to the ST700, then a total installation
megger test should be carried out, as defined in the General Testing Handbook.
6.1 ROUTINE INSPECTION OF SIGNAL EQUIPMENT
Check all signal heads/aspects for damage and take any necessary corrective
action.
Check all signal heads for correct alignment with their respective approaches.
Check all pole top cable connections; ensure that they are sound, secure and not
seriously corroded.
Check that all top caps are fitted and are not damaged.
Check that all poles are secure in the ground and are not leaning or damaged.
6.2 ROUTINE INSPECTION AND ELECTRICAL TESTING OF ST700
It is suggested that these procedures be performed in the order listed.
Examine the Lid and equipment mounting frame for serious damage. The Lid would
normally only be replaced if it has been damaged to the extent that its security has
been breached or that water or dirt is entering.
Open the door(s), both the main (if the cabinet has one) and the manual panel;
check that the screw-locks, lock and hinges operate freely. Inspect the door and
lock, and check the lock and catch-plate for security. Replace or tighten as
necessary. Lubricate as necessary with good quality penetrating type oil.
Undo the fixing bolt(s) and remove the Lid. Check the condition of the fixing bolts and
their associated chassis fixing thread, clean both and lubricate as necessary with
good quality oil. Inspect the stool-to-assembly seal and replace if necessary.
Inspect the manual panel gasket, ensuring it is intact and in the correct position.
Replace as necessary ensuring that the surface is clean before fitting.
Check the manual panel for any damage and replace if necessary. Check that all
functions operate correctly. Press the lamp test keypad and check that all LEDs are
operational.
The following tests will result in the signals extinguishing.
667/HB/27880/000
Page 77
Issue 8
ST700 GENERAL HANDBOOK
Test the 300mA RCD (if fitted) by pressing the test button. The breaker should
operate immediately.
Check the termination panel(s) and master switch panel within the Cabinet and
ensure that there are no loose fixings, or damage to these panels. Tighten any
loose fixings and carry out any repairs that are necessary.
Check the logic assembly and other assemblies within the ST700 are securely
fixed. Retighten loose fixings as necessary.
Check that all fuses are secure in their holders. It is strongly recommended that
the ST700 supply is isolated before any fuses are checked.
Check wiring and cableforms, particularly ribbon cables for damage. Replace or
re-route as appropriate.
The battery on the ST700 CPU PCB must be replaced if it has failed. Any
replacement battery should be suitably marked with an appropriate date label.
Having done this, the ST700 records should be updated accordingly.
The following tests require the ST700 to be powered and running normally.
Tests of the Voltage Drop of Neutral Conductors. This test should be carried out
during each periodic/annual inspection as a simple check of neutral cables, which
can also provide a good indication of the state of the intersection cabling.
(i) Take a digital multi-meter or voltmeter and set it to measure 240 volts AC
(RMS).
(ii) Select a phase and wait until its green has just terminated. Measure the
voltage between the Cabinet Assembly neutral and the green feed; the
voltage should be no greater than 4 volts (RMS) throughout the signal
cycle, except when the phase next goes to green. If the voltage between
the green feed and neutral is greater than 4 volts then do the following:
(1) Check all joints in the appropriate neutral cable run, ensure that they are
all tight and none are seriously corroded, replace or tighten them as
necessary.
Re-test cable
If the fault still persists then:
(2) Increase the number of conductors/cable cores used for the neutral.
Or
(3) Replace the cable that has failed the test.
667/HB/27880/000
Page 78
Issue 8
ST700 GENERAL HANDBOOK
Re-test the cable to ensure that corrective action taken has removed the
problem.
With the handset, check that all inputs used are operating correctly.
Test the maintenance socket RCD by pressing the test button. The breaker should
operate immediately.
The following checks should be carried out before leaving the site.
Check the manual panel gasket is intact and in the correct position. Replace as
necessary ensuring the surface is clean before fitting.
Inspect the cabinet base seal. If damaged, the affected area should be filled with
sand and re-sealed. For details see section 5.11.
6.3 ROUTINE SETUP CHECK
Check that the real time clock is set correctly as described in the Controller Handset
Handbook.
Use the time of day TOD command to check that the real time clock is running the
correct time. A true measurement of the accuracy of the real time clock can only be
gained if the clock with which it is compared has been accurately set up.
It is essential that the time be compared with an adjacent installation using a clock
that has been synchronised to that installation within the last 30 minutes.
6.4 REPLACEMENT OF PCBS
This section covers the removal and fitting of PCBs in the ST700. Safety
requirements and procedures are described to ensure that the board functions
correctly when fitted (e.g. PROM fitting).
When replacing PCBs only approved spares must be used. Use of any other
components may invalidate the Type Approval of the equipment.
Note that PCBs are not generally available separately as spares, but are included in
kits. If a PCB fails a new board may be taken from the replacement kit, or the whole
kit may be replaced. See Appendix A for part numbers.
6.4.1 Safety Requirements
Before replacing any fuses, PCBs etc., IT IS ESSENTIAL THAT THE POWER TO
THE ST700 IS ISOLATED. See the Safety Warning on page 2 for details.
667/HB/27880/000
Page 79
Issue 8
ST700 GENERAL HANDBOOK
Failure to isolate the supply before changing parts may result in damage to the
ST700.
6.4.2 General Requirements
When replacing PCBs the original PCB should be inspected and the following points
checked:
(a) Check the connectors on the PCB. Are any pins bent, broken or damaged in any
way? If there are, make a note of the PCB and pin number in the Controller Visit
Log Book as the ribbon backplanes may have been damaged.
(b) Check any ICs that are mounted in sockets and ensure that they are the correct
ones for the position and are securely fitted. Refer to the works specification for
further details.
A problem with a loose fitting IC or use of an incorrect one can usually be
rectified easily without having to fit a replacement PCB.
(c) Do not forget to record the replacement in the Controller Visit Log Book.
6.4.3 Access to PCBs in ST700 Cabinet Assembly
The ST700 CPU PCB is mounted directly on the outside of the ST700 Rack
Assembly hinged front plate and is easy to access once the Lid is removed from the
equipment mounting frame.
If a fault is suspected with the Phase Drive PCB, the whole Power/Phase assembly
is replaced as described in section 6.4.6.
If fitted, the I/O Board or OTU Board are fitted inside the ST700 Rack Assembly,
behind the CPU PCB.
Warning: To open the hinged plate, the 64-way Phase Control Ribbon cables at the
front of the ST700 Rack Assembly must be disconnected. Disconnection of the cable
disconnects all logic power from the CPU and therefore prevents the ST700
operating the lights, but it does not switch the incoming mains off. The mains
must be isolated at the master switch before any disconnection of cables or fuse
replacement takes place.
6.4.4 Access to PCBs in other Outercases
All ST700 Rack Assemblies installed in cabinets with 19” mounting kits provide full
access to the front face of the ST700 and have sufficient room to allow the hinged
front plate to swing open, giving access to the internal PCBs.
Access to the PCBs is the same as described in section 6.4.3.

ST700 GENERAL HANDBOOK
6.4.5 Replacement of CPU PCB
Ensure that the replacement PCB has the correct firmwares fitted and they are of the
correct variant and issue. Refer to the Works Order Specification for details.
The mounting pillars on the CPU are a nylon clip type and only require the clipping
mechanism to be released to allow the board to be removed. The pillars are retained
on the hinge plate by means of an integral clipping mechanism on the other end.
When the CPU is replaced, make sure that the clipping mechanism of the mounting
pillar is fully engaged.
Warning Care must be exercised when removing or inserting the green connectors
and their cables from the PCB, as strong extraction and insertion forces are required.
Be careful not to over flex the board, which could cause tracks to fracture and the
board to fail.
6.4.6 Replacement of Power/Phase Assembly
The Power/Phase assembly may be removed once the following have been carried
out:
Isolate the Mains to the ST700 at the master switch
Disconnect the 64-way Phase Control ribbon cable from the CPU
Unclip the earth lead from the hinged front plate
Remove the front plate2 holding the CPU (and I/O or OTU) and store carefully
Disconnect the earth wires from the fixing point in the assembly
Disconnect PL6, PL7, PL8 and SK2
Disconnect PL1 and SK1.
Warning Care must be exercised when removing or inserting the green connectors
and their cables from the PCB, as strong extraction and insertion forces are required.
Be careful not to over flex the board, which could cause tracks to fracture and the
board to fail.
Using a 10” Pozidriv No.1 screwdriver, loosen (do not remove) the four screws
holding the Power/Phase assembly to the equipment mounting plate. Lift the
assembly off the mounting plate.
Replace with the new Power/Phase assembly, checking that the part numbers are
the same, i.e. 2 phase, 4 phase or 6 phase unit.
Ensure that all links and fuses are set correctly (i.e. in the same position as the
original unit) as described in section 5.15.
Reconnect PL1, PL6, PL7, PL8, SK1, SK2 and the earth wires.

The front plate needs to be at 90º when it is fitted or removed. Push the front plate
up and remove from the bottom hinge pin. Pull down to release the front plate from
the top hinge pin.
667/HB/27880/000
Page 81
Issue 8
ST700 GENERAL HANDBOOK
Replace the hinged front plate holding the CPU PCB and, if fitted, the I/O or OTU
PCB.
Replace all the cables to the CPU. Clip the earth lead to the front plate.
Restore power to the ST700.
Note: The new Power/Phase assembly is supplied with a chassis door fitted. It is not
necessary to replace the door when the Phase Drive PCB has failed. The old
Power/Phase assembly should be returned to Siemens Poole with the replacement
door.
6.4.7 Replacement of Manual Panel PCB
First unplug the cable connecting the manual panel to the CPU PCB.
The manual panel is held to the main Cabinet Assembly by a number of screws that
need to be removed. After removing these screws the panel may remain held in
place by the sealing strip. Ease the panel away from the housing, gradually working
from one corner, taking care not to scratch or otherwise damage it.
The replacement panel should be mounted with a new sealing strip to prevent water
ingress. After fitting, reconnect the cable to the CPU PCB.
Where an Internal Manual panel is fitted, it may be removed directly by removal of
the screws holding it to the 19 inch panel; it may be easier to remove the 19 inch
panel from the rack first. No sealing is required on refitting.
6.4.8 Replacement of Expansion I/O or OTU PCB
Removal of the I/O or OTU PCB may be done once the Mains to the ST700 Rack
Assembly has been isolated at the master switch, the 64-way Phase Control ribbon
cable has been disconnected from the CPU and the hinged front plate has been
opened.
Ensure that the replacement PCB has the correct firmware and PLD fitted at the
correct variant and issue. Refer to the Works Order Specification for details.
The I/O or OTU PCB is removed by removal of the screw fixings (4 off) which secure
it to the inside surface of the hinge plate. Ensure all the cables are fully disconnected
before the board is removed, and fully inserted following the replacement of the
board.
6.5 REPLACEMENT OF MAINS POWER SUPPLY UNIT
The spare Mains Power unit is provided as part of the Power/Phase Assembly. It is
not necessary to replace the whole assembly if the power unit has failed, providing
the failure has not damaged other components.
667/HB/27880/000
Page 82
Issue 8
ST700 GENERAL HANDBOOK
The Mains PSU may be removed once the following have been carried out:
The Mains to the ST700 Rack Assembly has been isolated at the master switch
The 64-way Phase Control ribbon cable has been disconnected from the CPU
The hinged front plate has been opened.
Remove the cables and connectors connected to the PSU, then release the nylon
mounting pillar clips that attach the PSU to the heatsink cover of the Phase Drive
PCB. The clips are retained on the heatsink cover by means of an integral clipping
mechanism on the other end.
When the PSU is replaced, ensure that the clipping mechanism of the mounting pillar
is fully engaged and all the cables and connectors are securely fitted.
Re-assemble the Rack Assembly.
6.6 REPLACING OTHER COMPONENTS
Only approved spares must be used when replacing any components. Use of any
other components may invalidate the Type Approval of the equipment.

7. SELF-TEST FACILITY
The self-test facility can be used to check the hardware fitted to the controller, even
before a configuration is loaded. It is designed to be used both in the factory by
production and on the street by installation/ maintenance engineers.
Self-test is initiated by holding down the level 3 access button while switching on the
power to the controller. The button should be released once the green heartbeat
LED starts to flash.
The green heartbeat LED continues to flash during the self-test unless a fault is
detected when the red system error LED illuminates.
Connecting a 20 character by 4 line handset displays information about the checks it
is performing, such as the firmware issue and the lamp supply voltage, both dim and
bright, and detail any faults found.
Self-test performs the checks detailed on the following pages and produces error
messages if faults are detected.
While the self-test is running, the manual panel can be checked. Pressing each
button on the panel should illuminate the associated LED. To distinguish this from
normal operation, the LED flashes at a fast rate while the button is depressed. Note
that the „Lamp Test‟ button illuminates all the LEDs, as it does for normal operation.
To test the signals on/off switch and the cabinet alarm LED, switching the switch to
the signals „on‟ position illuminates the cabinet alarm. Switching it to the „off‟ position
extinguishes the cabinet alarm indicator. Note that the signals on/off switch does not
affect the self-test in any other way.
Resolving problems with lamp switch cards and triacs:
When various tests fail, the handset may display information such as:
No voltages on:
R-00000000+00000000
A-00000002+00000002
G-00000000+00000000
-ve Peak +ve Peak
identifies the test which has failed
outputs from the red voltage monitors
outputs from the amber voltage monitors
outputs from the green voltage monitors
The numbers are in hexadecimal notation and so each of the eight digits encodes
four phases, as follows:

So in the above example, there are no voltages on Phase B amber (or Wait). Has
the wait fuse blown?
On power-up, the self-test facility checks the integrity of the main processor
board:
RAM
DPR
PRG
XTL
DPR
FAULT
RAM FAULT
PROM FAULT
FAULT
R/W FAULT
All the above faults point to problems internally on the main processor card.
Checks communications with the secondary / phase bus processor:
P/Bus CPU....
If the processor cannot be detected, then the self-test will wait indefinitely at this
point with the red system error LED illuminated. Check that the processor and its
firmware are fitted.
Examines the lamp switch cards to see how many are fitted:
No L/S Cards Found
No cards were detected. Either the lamp switch or the processor PCB could be
faulty.
Waits for ZXO synchronisation and checks the mains frequency:
667/HB/27880/000
Page 85
Issue 8
ST700 GENERAL HANDBOOK
ZXO Sync’d...
If the phase bus processor cannot synchronise to the mains zero cross-over signal,
then self-test will wait indefinitely at this point with the red system error LED flashing.
Mains Freq Error
If the mains frequency is more than 5% out from either 50Hz or 60Hz.
Checks all the ADC test voltages on all of the lamp switch cards:
ADC Tests....Failed
ADC Test Readings
0.0V 2.5V 5.0V
B0+ nnnn nnnn nnnn
B0- nnnn nnnn nnnn
... .... .... ....
If the test fails, then the readings from each board, taken at both the positive and
negative mains peaks for each of the two test voltages (0V and 2.5V) are displayed
on the handset.
Ideally the values should be 0 and 128.
Checks that the lamp supply and voltage monitors are detecting no mains:
L/Supply Off=240V
L/Supply Stuck On
If a lamp supply is being detected, then this implies that the lamp supply relays are
all switched on (very unlikely) or the lamp supply monitoring transformer (on the
power distribution card) has failed.
V/Mons Off...Failed
R-00000000+00000001
A-00000000+00000000
G-00000001+00000000
If any of the voltage monitors appear to be detecting mains, even though the lamp
supply and all the triacs are switched off, then this implies a problem with the
hardware on the lamp switch card.
Initialises the phase bus processor:
P/Bus Init...
667/HB/27880/000
Page 86
Issue 8
ST700 GENERAL HANDBOOK
Bad L/S Cards
Once initialised, the phase bus processor performs more thorough checks on the
lamp switch card and may detect faults.
Checks the monitor validation signal:
M/V Test ....Failed
Mon Val Failed
The monitor validation signal is generated by the main processor to check the phase
bus processor, so a failure is probably due to a faulty processor card.
Step 1 Complete, Start Step 2:
At this point, the self-test has successfully checked-out the logic side of the cards. It
then displays a scrolling pattern on the amber LEDs to show that the first part of the
self-test is complete.
This pattern remains until the operator presses the level 3 button to confirm that the
self-test may switch on the lamp supply and continue its tests.
After the level 3 button is pressed, self-test switches on the lamp supply.
Towards the end of this second sequence of tests, it tests all the triacs by switching
each one on in turn for a very short period of time.
If standard HI 12V halogen lamps are used (with a transformer in the signal head),
then this pulse will not be seen on the street and so the signals need not be covered.
However it may be possible to see the pulse on lamps that are not driven by any
transformer, i.e. that run directly off the 240V.
If in doubt, all non-HI signal heads, i.e. 240V lamps, LED
Signals and 48V ped signals, should be covered before
proceeding any further with the self-test.
Self-test switches on the lamp supply and then checks that the voltage
monitors still show no mains (triacs still switched off):
V/Mons Off...Failed
R-00000000+00000001
A-00000000+00000000
G-00000001+00000000
667/HB/27880/000
Page 87
Issue 8
ST700 GENERAL HANDBOOK
If any of the voltage monitors appear to be detecting mains, then it would imply that
those triacs are not holding off the mains and the lamp switch card should be
replaced.
L/S Supply Failure:
L/S Monitor Fault
The lamp supply can be detected on the voltage monitors, but no signal is present
from the lamp supply monitoring transformer. Replace the lamp switch card.
L/Supply Failure
No lamp supply has been detected by the lamp supply monitoring transformer but
further investigations by the self-test facility cannot determine the cause. Check the
lamp supply circuits relays, fuses, etc., in and around the power distribution unit.
Also check that the dim connector SK2 is connected. N.B. Links are required on this
connector even if no transformer is required.
Checks that each lamp supply relay can switch off the lamp supply
independently:
SSR Fault
Relay A Fault
Relay B Fault
Failure of any of these tests implies that the relay is not switching off, i.e. that it is
either welded closed or the control signals from the main processor card are stuck
active.
Checks that the dimming relay is functioning:
Dimming Fault
A fault is only logged on the dimming relay if the dim lamp supply is more than 75%
of the normal lamp supply, i.e. that the dimming relay seems to have no effect on the
lamp supply.
Note that this test does not fail if there is no dim lamp supply, e.g. if no dimming
transformer is fitted, since self-test may be performed on the just the controller rack.
Therefore, the dim voltage should be checked manually, e.g.
Dim L/Supply=160V
667/HB/27880/000
Page 88
Issue 8
ST700 GENERAL HANDBOOK
Checks all of the triacs in turn by applying a very short pulse to each
phase’s colour:
A/Red:Extra Sigs On
R-00000001+00000001
A-00000001+00000001
G-00000001+00000001
A fault will be logged if extra signals are detected as on when one particular aspect is
pulsed. This would normally imply a short-circuit in the street cabling or a open
neutral connection.
No Voltages On...
R-00000000+00000000
A-0000000A+0000000A
G-00000000+00000000
A fault will also be logged if no voltages were detected, e.g. when one of the fuses
has blown.
In the example above, 0000000A represents phases B and D (see Figure 22), so
Amber (from RAG down the left-hand side) shows that the pedestrian Wait indicators
have no voltages present. Check the fuses F6 and F8 and the 48V output from the
dimming transformer for example.
At the end of the test, the self-test switches off the lamp supply and displays a
multicoloured scrolling pattern on the LEDs to show that all the tests have passed
successfully.
It also illuminates a series of LEDs to identify which cards on the extended system
bus have been detected. A full list is displayed on the handset.
After a few seconds, self-test will repeat the second part of the self-test allowing the
controller to be soak tested.
