2.3 Driver Module
The Driver module contains the mains power supply, a processor board a battery charger/relay driver board and the modem.
The power supply provides 12 volts and 5 volts dc. Both are high current outputs. Up to 12 Amps at 12 volts is required for the heaters in the displays and a nominal current is used by the modem. The 5 volts provides the LED drive current as well as providing the logic supply for the processor and display. Extensive fusing is provided on both supplies as the short circuit currents from the power supply are more than 25A (12v) and 60A (5v).
667/HB/30325/000 Page 10 Issue 1
SIESIGN 150 H ANDBOOK
The processor board is the standard board also used for Motorway VMS and Urban
‘extrusion signs’. Four serial ports are present, allocated as follows:-
Serial channel 1
Serial channel 2
Serial channel 3
RS485 isolated
RS232

An on-board lithium battery supports the real time clock and the RAM used for the fault log.
Provision is made for a rechargeable backup battery to provide power for the processor and modem only. This option is not yet available but the battery charger pcb is fitted as it also contains the relay drive circuits.
The Modem depends on the customer’s requirements but at the time of release of this handbook only ‘radio’ types are used, i.e. there is no land line option.
2.4 Display Module
Each Display Module contains 2 LED based display boards each having three 7 x 5 dot matrix characters, i.e. 6 alphanumeric characters per Module. The pcbs contain all components required for decoding into row and columns and driving the LEDs. Anti condensation heaters are provided to minimise condensation on the character window.
A thermostat is used to disconnect the heating in warm conditions
Power and serial data are sent to the Display Module using a composite cable containing 4 power cores and a twisted pair for data.
As the RS485 line is routed to all display boards, each board must have its own unique address. This is programmable using a separate port on the board. The address is stored on board in non-volatile RAM.
The anti-condensation heating takes the form of 3 wirewound resistors fitted to the bottom support rail. These are connected in series, via a thermostat on the top rail, to the incoming 12 volt supply.
3. SPECIFICATION
3.1 Optical

3.5 Site Current Calculation
The current required to drive a UVMS is made up of three components:
(a) that required to run the electronics
(b) that required to power the heaters
(c) that required to illuminate the LEDs when a message is being displayed.
(a) Electronics
Estimated as being equivalent to 1.5A at 5V continuous or 7.5W. Allowing for
75% efficient power supply gives 10 watts at 230V.
(b) Heaters
Each display draws 2 Amps at 12 volts when the heaters are active, i.e. 24 watts. This equates to 32 watts per display at 230v. The heaters come on when the temperature at the top of the display falls to 20°C and switch off again when the temperature rises to 30°C. Note that self heating of the display and solar heating mean that these limits do not correspond directly to air temperatures.
(c) LEDs
The average number of LEDs illuminated when a character is activated is 15.
For the intelligent character signs the power is derived from a 5V power supply at 28mA per pixel. This gives 2.8 watts per character at 230V.
667/HB/30325/000 Page 12 Issue 1
SIESIGN 150 H ANDBOOK
These figures can be used to calculate power consumption for a particular sign usage, and an example is shown below:
Example
A sign with three displays (of 6 characters) showing car park vacancies from 7am to
11pm and blank the rest of the 24 hours. The heaters are on for 24 hours
Electronics

24 hours at 10w
24 hours at 96W
= 0.24kWh
= 2.30 kWh
16 hours at 3 x 6 x 2.8W = 0.81 kWh
Total power usage for 24 hours = 3.35 kWh

667/HB/30325/000 Page 14 Issue 1
4.3 Installation of Driver Module
SIESIGN 150 H ANDBOOK
4.3.1 Safety
Installation of the Driver unit requires the Installer to work at a height that depends upon the site design. Only persons who are suitably experienced and trained to use suitable access equipment must undertake this work.
4.3.2 Fitting
Refer to the Siesign 150 Mechanical Build Document 667/GC/30326/000.
Offer the Driver Unit to the studs on the top panel so that the light sensor is at the top and secure with the nuts and washers supplied with the unit.
4.3.3 Wiring
Wiring to Displays
The Driver Module is supplied unwired - the cable entries have blanking plugs. The
Display Modules have the cables attached and the cable glands are loose on the cables. The cables are supported and protected with a cable handling system. This has to be built up on site from the items supplied. The cable handling system covers all cables to minimise vandalism and to present a neat appearance.
The system is based on an aluminium angle section aluminium covers. It is fitted to the aluminium extrusions on the top and bottom of the sign plates using “T” bolts.

After triming to length, the cover should be pop rivetted to the vertical cover.
Horizontal cable covering arrangement
The supporting angle should be fitted to the extrusions using “T” bolts, washers and nuts. A short bolt should be used to prevent obstructing the angle as this area is required for cables:-
Extrusion
Cable tie minimise length
Vertical cable support (plan view)
Each display may be connected any terminal blocks in the Driver Module. The top
Display Unit would normally go to the leftmost cable gland but it is allowable to use any cable gland for any cable. The other consideration is that if only one or two displays are to be fitted, the top cover is not needed.
Wiring to pole base
At the top of the belled pole, route the flexible armoured power cable and the Diagnostic terminal cable through the flexible conduit and gland and drop down to the MDU at the base. Do not offer the cable gland into the pole aperture at this stage. Pass the 4 sq mm green yellow earth cable through the conduit. Secure the cable gland on the end of the conduit into the pole aperture.

4.4 Installation of Display Module
SIESIGN 150 H ANDBOOK
4.4.1 Safety
Installation of the Driver unit requires the Installer to work at a height that depends upon the site design. Only persons who are suitably experienced and trained to use suitable access equipment must undertake this work.
4.4.2 General
The pcbs in the display modules are programmed with an address so the modules must be fitted in the correct position. For a new site they are marked prior to delivery.
If it is necessary to use an unprogrammed display then the address must be set up.
Refer to the details and notes on the Siesign 150 Mechanical Build Document
667/GC/30326/000 .
Offer the Display Unit to the studs on the panel (vent downwards) and secure with the nuts and washers supplied with the unit. Note that normally the cable enters the
Display Unit on the right hand side. If required the cable can be re-routed internally so that it enters on the left hand side. If this is required, remove the rear panel, slacken the cable gland and pull the cable through the gland into the box. Swap the cable gland with the blanking plug from the hole on the other side of the box. Run the cable along the bottom of the box (inside) and through the gland. Retighten the gland.
4.5 Installation Electrical Testing
Document 667/HE/20664/000 covers installation testing of traffic control equipment. It includes procedures concerning tests associated with traffic signal poles, Controller startup etc which are not relevant to VMS Signs. Installation testing of the Siesign 150 signs generally follows the procedures in this document. The following sections cover particular procedures regarding the signs.
4.5.1 Visual Inspection

This test is to be carried out prior to connecting the tails being connected to the
Electricity Supplier’s fuse.
Remove the Switch Cover from the mains components.
Ensure the Mains Isolation Switch and the RCD are switched on and that the ‘sign’ fuse is in place.
Test
Connect the live and neutral tails together. Switch the Master Switch on. With the
Insulation test instrument (set to 250V operation) carry out the following tests:
- Connect between the main ground stud and the Mains/Neutral tails.
Test insulation impedance. It must be greater than 10 megohms. Record the value in the Installation Test Results form.
4.5.3 Polarity Test
The object of this test is to check that the sign is connected to Line and Neutral in the correct sense.
At the master switch check that the voltage measured from Line to Earth is approximately 240V AC and the voltage measured from Neutral to Earth is less than
10V AC.
4.5.4 Earth Loop Impedance Test
Earth Loop Impedance tests are carried out at any points in the system where mains and exposed metal work are present. The fault path within the installation comprises of the live conductors, control equipment and the CPC. The fault path external to the installation (Ze) contains the supply authority's transformer windings, the live conductor and CPC of the supply authority's distribution network, or the earth electrode. The
Earth Loop Impedance test will include both elements described above.
667/HB/30325/000 Page 18 Issue 1
SIESIGN 150 H ANDBOOK
The Earth Loop Impedance test results are required to ensure that in the event of an earth fault (or a short circuit fault) the protection devices e.g. fuses will disconnect within the time limit as specified in BS7671 (IEE Wiring Regulations).
For fixed equipment such as the Siesign 150 equipment, the specified disconnection time laid down by BS7671 is 5 seconds and for equipment connected via sockets the specified disconnection time is 0.4 seconds.
This test is carried out after the Electricity supply has been installed.
Preparation
After ensuring that the cable is not live, connect mains to the sign’s distribution box.
The sign should be switched on and operating normally unless otherwise stated in the following subsections.
SAFETY
During the test ensure that NO person is in contact with any part of the sign or the mounting pole.
4.5.4.1 Tests at Base of Belled Pole
Using an LT5 tester or equivalent: Connect the Red probe to the Live input at the
Mains Isolation Switch and the earth test probe of the tester (Black probe) to the following points in turn and carry out an Earth Loop Impedance Test for each point:
(a) Main Earth on MDU
(b) Earth stud on Pole
(c) Earth pin of the maintenance socket
The maximum allowable value is 5.08
Ω
(based on BS88 fuse and 5 seconds disconnect time).
If the measurements exceed this value, do not proceed with further testing and report the supply as out of specification to the customer concerned.
If the supply Company can not improve the characteristics of the supply, then a permissible solution is to fit a 300mA RCD to protect the whole installation. However this will require a separate Mains pillar as there is no room within the belled pole.
The maximum allowable earth loop impedance of an installation following an in-line RCD is calculated using the following formula:
Z = 50 X 1000
I(mA)
Where I(mA) is the operating current in milliamps for the RCD.
Note: For 300 mA RCD is recommended not to exceed 100
Ω
and for a 30 mA RCD it is recommended not to exceed 1000
Ω
.
Note: 30mA RCD is not recommended on a sign as nuisance tripping can occur.
667/HB/30325/000 Page 19 Issue 1
4.5.4.2 Tests at Driver Module
SIESIGN 150 H ANDBOOK
SAFETY
During the test ensure that NO person is in contact with any part of the sign or the mounting pole.
Using an LT5 tester or equivalent: Connect the Red probe to the Live input at the mains terminal block and the earth test probe of the tester (Black probe) to the following points in turn and carry out an Earth Loop Impedance Test for each point: a) Earth stud on panel b) Case of mains psu close to mains input c) One of the fixing studs used to fix the module to the sign face.
The maximum allowable value is 5.08
Ω
(based on BS88 fuse and 5 seconds disconnect time).
4.5.5 Maintenance Socket RCD Test
This test is performed with the Seaward RC500 or similar meter. The test measures the actual disconnection time of the RCD.
Connect the RCD tester into the maintenance socket. Set the test trip current to 30mA, press test button: The maximum allowable trip time is 0.2 seconds.
Reset the RCD. Set the trip current to 150mA and re-test: The maximum allowable trip time is 0.04 seconds.
If either test fails replace the RCD.

Luminance level switches (S3) allow adjustment of the lantern and character
LED light outputs. The luminance level is determined by the ambient light level sensors. Level 1 corresponds to low light levels and level 4 to high light levels.
For each light level one of four sub levels may be set. The light output for both
LEDs and lanterns defined by the sub levels is determined by the configuration
EPROM and can be changed.
For Siesign 150 signs always set the luminance switch S3 to all 8 bits being closed.
Note: The diagnostic terminal can be used to determine which luminance level the sign is operating in by selecting the Monitor Light Sensors option (See
Appendix A4.4.4).

±
10 seconds after the removal of mains power.
(f) Switch the master switch back on and check the processor PCB Run and
Watchdog LEDs as in (a) above.
(g) Set the battery switch (S1) on the processor PCB to ON/
(h) Signs with PAKNET only -
To register the RP9 Radio-Pad, ensure power is connected and then press and hold the Test Button for 3 to 5 seconds. Only release the test button once the yellow service light has started to flash slowly. Registration is now performed automatically, which may require up to one minute. After registering, the service light remains lit if a radio base station can be found and used.
If the service light is lit, a test call can be made to the network by pressing the test button twice within one second. On the second depression, the service light is extinguished for half a second.
A successful test call is shown by the service light remaining permanently lit after half a second; this indicates that the Radio-Pad is operating correctly. If a fault still exists then check the data cable or the terminal.
An unsatisfactory test call is indicated by the service light turning on and off four more times, finally remaining on. If this happens, then try another

6.3.4.1 Introduction
The Intelligent Character Test software (which is part of the Maintenance Kit) allows
UVMS Intelligent Characters to be operated directly from a Windows 95/98 PC without using the UVMS CPU PCB. Thus it is suitable for both bench testing of characters and complete signs.
In all cases the program tries to write to and display on as many characters as it can
(unlike the UVMS CPU PCB, which only allows a display to be shown if all characters are fault free) regardless of how many may be faulty.

1st Screen - Warnings and Password
Ensure the warnings are heeded and then enter the password (ICT ENTRY).
2nd Screen - Sign Size
Select the COM port that the Converter is attached to if different from COM 1.
Then enter the number of rows on the sign (maximum 4) and the number of characters per row (maximum 12).
3rd Screen - Sign Configuration
Inverted rows do not apply to Siesign 150.
Select the character size (3 per PCB = 150mm)
The program now ‘draws’ the sign on the screen and data for each line can be entered.
Only those letters, numbers and punctuation marks allowed by the HA can be displayed with one exception; entering a # causes all LEDs for that character to illuminate.
The "SEND TO SIGN" button sends the data displayed on the screen to the sign.
The "TEST ALL LEDS" button illuminates all LEDs on each character in turn then redisplays any data.
The DOT below each display shows:
GREEN if the Character is OK
RED if it is faulty
YELLOW as it is being tested
WHITE as data is being sent.
Brightness can be adjusted with the BRIGHTNESS slider and the speed at which the sign is written to can be adjusted using the COMMS SPEED slider, which is useful for slowing down the test sequence.
6.3.4.4 Hints
1. Remember some PCB faults can hog the line so be prepared to isolate sections of the sign.
2. If spare character PCBs are used, they must have their addresses set for the positions that they occupy in the display.
3. Do not forget to re-address character PCBs that are moved about in the sign or they will appear out of sequence (if two character PCBs end up with the same address they will interfere unpredictably).
667/HB/30325/000 Page 33 Issue 1
SIESIGN 150 H ANDBOOK
6.3.4.5 Completion
At the completion of character testing, power down the sign and replace any fuses and connections removed during the test (described in section 6.3.4.2).
Connect the Maintenance Terminal as described in Appendix A and set a message that exercises all characters.
6.4 Replacement of Component Parts
Before replacement of any components takes place, the sign should be completely switched off. Remove the fuse at the base of the pole.
6.4.1 Replacement of Processor PCBs
In the event of a PCB requiring replacement it must be replaced by a part of the same type and the same or higher issue state. Before removing the PCB note all switch settings and configure the replacement PCB in a similar manner. Swap the EPROMs and PLD on the faulty PCB with those from the replacement PCB. In order to replace a
PCB, all the connections to that PCB should be removed. The PCB can then be removed from the panel. This is achieved by removing the retaining clips (or screws) at each corner.
When handling PCBs or electronic components, all reasonable precautions must be taking to prevent the damage of components by ESD.
6.4.2 Replacement of Power Supply
The Power Supply Unit is mounted on a sub-panel on the right hand side of the main panel. After ensuring that the mains supply is completely isolated, the procedure for replacement is as follows:
• Remove ELV connections from the power supply
Remove LV (mains voltage) connections from the power supply •
The sub-panel can now be unscrewed from the panel, allowing the PSU to be replaced with a new unit. Replace the sub panel and reconnect the wiring.
Inspect the psu connections and restore the mains power and check the rails as follows:-
12V Rail 12.0
±
600mV.
5V Rail 5.0
±
250mV.
6.4.3 Replacement of Miscellaneous Panel Mounted Items
All units on the mounting panel are fastened using studs/nuts/washers or rivnuts. In order to remove any item, the necessary fixing must first be unfastened.
667/HB/30325/000 Page 34 Issue 1
SIESIGN 150 H ANDBOOK
Any item that is removed should be replaced by an identical item, identified by its STCL
Part No.
6.4.4 Replacement of Characters
The character PCBs are screwed onto power rails. To replace a PCB follow the procedure below:
•
Remove the power from the display: This may be done by removing the appropriate fuses in the Driver module or by powering down the whole sign.
•
Unclip the inter-pcb connector.
•
Unscrew the 4 screws holding the character PCB in place.
•
Remove the PCB and replace with the new board. Screw in the 4 screws loosely and align the PCB so that the inter-PCB connectors can be connected.
•
Connect the inter-pcb connector and tighten the pcb fixing screws.
•
If the pcb has not been pre-configured then follow the procedure in
6.4.4.1
•
Use the removed PCB’s configuration label, and the configuration terminal to configure the new character PCB. See below for details.
•
Fill in the details of the configuration label on the new PCB.
6.4.4.1 Configure New Character PCB
•
Disconnect the inter-character connectors.
•
Run the “Intelligent Character Configurator” software on a PC as defined in Appendix E. See section 6.3.4.2 below for details of how to set up the PC to operate the software.
•
Connect the PC to the replacement character, as shown in Figure 8.

The light sensor is mounted at the top of the sign enclosure. To replace a light sensor perform the following steps:
•
Disconnect the red and white wires to the light sensor
•
Unscrew the light sensor nut
•
Remove the light sensor.
Ensure that any sealing rings are intact. The light sensor can now be replaced. The procedure for replacing the light sensor into the sign is the reverse of the removal procedure.
Once the faulty light sensor has been replaced it should be checked for correct working as follows:
•
Connect the Diagnostic Terminal
•
Display the ‘Monitor Light Sensors screen’ and check that the replaced light sensor is giving sensible readings.
•
Display the ‘Complete Fault Log’ and check that an entry has been placed in the fault log showing clearance of the light sensor failure.
•
Cover up the light sensor so that the readings are very low.
•
Display the ‘Monitor Light Sensors screen’ again and check that the light sensor is giving very low readings.
•
Uncover the light sensor.
Display the ‘Complete Fault Log’ and check that an entry has been placed in the log that the light sensor variation failure has cleared.

Appendix D - Use of Diagnostic Terminal
D.1 GENERAL DESCRIPTION
The Diagnostics Terminal consists of a portable personal computer and installed software that operates on PC running Microsoft Windows 95/98. It has been designed to aid maintenance engineers with the varied day to day interface needs of the different variable message signs. Simple to use menu driven operations enable set-up and maintenance tasks to be undertaken with ease.
Words enclosed by chevrons, e.g. <Enter>, <Esc>, indicate computer keys.
D.2 HARDWARE DESCRIPTION
The hardware required to run the VMS Diagnostics Terminal software is a personal computer (see Appendix E) with a suitable lead to connect to the RS232 serial port of the processor as shown in Figure 10.

Figure 10 - Diagnostic Terminal Hardware Setup
D.3GETTING STARTED
D3.1 Introduction
The Diagnostics Terminal software is supplied on a 3.5" 1.44 Mbyte floppy disk. It comes with an automatic installation program called SETUP. This program creates directories as needed and transfers files from your distribution disks to the PC's hard disk. A minimum of 1 Mbyte of disk space is needed on the destination drive for the
Diagnostics Terminal software; in addition to space required for any report data files that may be created when the software is run.
It is assumed that MS-DOS and Windows have already been installed on the portable
PC and that the operator is reasonably familiar with DOS commands.
D3.2 Installing the Diagnostics Terminal Software
The Diagnostics Terminal software is protected to stop unlicensed versions of the software being generated. The Customer issued disks are limited to a certain number of installations. If subsequent installations are attempted the software fails to be invoked.
To install the Diagnostics Terminal software:
•
Boot up the portable PC.
•
Ensure that the DOS system prompt is displayed.
•
Start Windows.
•
Insert the installation disk (Diagnostic Terminal DISK #1 part number
667/1/25625/000) into drive A.
667/HB/30325/000 Page 40 Issue 1
SIESIGN 150 H ANDBOOK
•
From File Manager select drive A and then double click on the setup program.
•
Follow the instructions displayed - this involves confirming or changing the destination pathname. The Windows group and icon are all created automatically.
Using Diagnostics Terminal Software on Windows 95
There is an identified problem running the software with Windows 95 that can be overcome in the following way:
•
From the Start button select Settings and then Control Panel
•
Double Click the System icon. This opens a dialog titled System Properties
•
Select the Device Manager tab and scroll down the list until you reach an item labelled Ports (COM and LPT)
•
Double Click the Ports item to show all the COM and LPT ports on the PC
•
Select the COM port that is used to connect to the sign, and press the
Advanced button
•
Select the Port Settings tab and select the Advanced button from the displayed dialog
•
Remove the tick from the check box labelled Use FIFO Buffers
•
OK all the displayed dialogs and close the Control Panel.
It is now possible to run the Diagnostic Terminal and connect to the sign via the
RS232-485 converter.
Note: Some applications and utilities that make extensive use of the COM port
(such as serial printers, or network comms applications) may require this to be re-enabled when used. If other applications use the COM port it is possible to re-enable the FIFO buffering and only disable it when using the VMS Diagnostic Tool. To re-enable the FIFO buffering follow the procedure outlined above, but make sure the Use FIFO Buffering check box has the tick enabled.
D3.3 System Start-Up
Start the program from Windows. When started, the terminal attempts to establish a connection with the Sign. If it is unable to do this, the software notifies the operator and exits.
Note: The terminal software must be exited before disconnecting or switching the computer off, as the terminal must establish a disconnect with the
Sign.

If the ‘Reset’ button is selected, a message confirms if the Fault Log has been cleared.
D4.3.2 RT Clock
This facility enables the sign clock to be both read and set.
On selection of this option, the sign clock is read and the retrieved data displayed in a dialog box. Then either ‘Quit’ or change the time and/or date values and ‘Send’ the changes.
If ‘Send’ is selected and a password has not previously been entered during the current session, the operator is prompted to do so. When a valid password has been entered, the time and date are transmitted to the sign and used to reset the clock. The clock is immediately re-read and the new values sent back to the terminal and displayed.
Note: The data entry dialog box performs validation checks on the time and date values entered before sending them to the sign. Any errors are notified and the software offers an opportunity to correct them before proceeding. The terminal will not send an invalid date or time to the sign.

D4.3.3.1 Set EMS Message
This option enables the operator to set the message on an EMS sign. It is password protected similar to the Reset Fault Log option.
The system checks the type of the sign connected. If the sign type is not EMS, an error message (see Appendix A5) is displayed to inform the operator of this and the option is aborted. Otherwise, the system proceeds and displays STATUTORY WARNINGS that must be read carefully to make sure that all the conditions are met before proceeding.
Select ‘Cancel’ to abort if these conditions have not been met.
This facility enables the operator to set the text message on the sign, together with the lantern requirement (lanterns ON/OFF) and the lantern override switch (ON/OFF). The lantern requirement and lantern override switch are set by means of check boxes; an X in the check box indicates that the option is set to ON.
Note: If the ‘lantern override’ switch is set to OFF, the lantern requirement setting is ignored.
To specify the text to set, enter the text directly in the text message field, noting that to move to the next line press <CTRL + RTN>. The text will only be set on the sign if it is compatible with the sign’s size. There is no error message concerning a set not being accepted.
To set the message on the EMS to one of the stored messages, the first character in the text message field must be ‘#’ and must be followed immediately by the Stored
Message Code (with no intervening spaces or tabs). The Stored Message Code must be in the range 0 to 47, e.g. #25; if it is not within the range an error message is reported (see Appendix A5). The terminal will not send an out of range Stored
Message Code to the sign.
This facility is also used to test all the characters on a sign during a routine maintenance visit (see sections 7.2.1 and 10.2.1). This may be achieved by setting all the pixels of all the characters on one row of the sign, asking for a visual check and moving on to the next row. The way to set all the pixels on one character is by pressing
<Alt> 0146 at the numeric keypad.

This option, which enables the operator to set the Aspect on an EMI sign, is not used for UVMS.
D4.3.3.3 Set Dim/Bright
This option enables the operator to set the Dim/Bright level on EMS and sign types. It is password protected similar to the Reset Fault Log option.
On selection of this option, after checking for entry of a valid password, the system displays STATUTORY WARNINGS that must be read carefully to ensure that all the conditions have been complied with before proceeding. Select ‘Cancel’ to abort if these conditions have not been met.
The level is set to DIM or BRIGHT by means of “radio buttons”, only one of which may be selected at any one time.
Select ‘Quit’ to leave this option.
D4.3.3.4 Set Lantern Override
This option enables the operator to set the lantern override switch on EMS signs to either ON or OFF. It is password protected similar to the Reset Fault Log option.
On selection of this option, after checking for entry of a valid password, the system checks the type of the sign connected. If the sign type is not EMS, an error message
(see Appendix A5) is displayed to inform the operator of this and the option is aborted.
Otherwise, the system displays STATUTORY WARNINGS that must be read carefully to ensure that all the conditions have been complied with before proceeding. Select
‘Cancel’ to abort if these conditions have not been met.
The lantern override is set by means of a check box; an X in the check box indicates that lantern override is set to ON.
Select ‘Quit’ to leave this option.
Note: If the lantern override switch is off, the lantern requirement settings are ignored.
D4.3.4 Simulator Faults
For security reasons this option is protected by two passwords. If a password has already been entered during the current session, only the second password is required.
667/HB/30325/000 Page 45 Issue 1
SIESIGN 150 H ANDBOOK
On selection of this option, after checking for entry of a valid password, the system displays a STATUTORY WARNING that must be read carefully to ensure that all the conditions have been complied with before proceeding.
A dialog box is displayed, with a list of faults relevant to the type of sign connected. If the option has been accessed during the current session, the previously sent faults are highlighted, if the option has not been accessed before, then no faults are highlighted.
A fault can be selected or de-selected by highlighting or un-highlighting it respectively.
When the chosen faults have been selected, ‘Send’ can be selected to send the highlighted faults. None or more faults can be sent. If ‘Cancel’ is selected the dialog box is refreshed, and displays the faults previously sent (if any). If ‘Stop’ is selected the option is aborted without sending any faults.

D4.4.1 Start Factory Self Test
This facility enables the operator to initiate a Factory Self Test. This test is used to soak test the signs in the factory. Each test consists of five sign settings as follows:
1..First set of alternate pixel rows set, lanterns off.
2..Second set of alternate pixel rows set, lanterns off.
3..First set of alternate pixel rows set, amber lanterns flashing (if fitted).
4..Second set of alternate pixel rows set, lanterns off.
5..Sign blank, lanterns off.
Once a self test has been started, the sign takes over and performs the actual tests.
For security reasons this option is protected by two passwords. If a password has already been entered during the current session, only the second password is required.
Note: This facility must not be invoked outside the factory even if the second password is known.
Before selecting this option, ensure that the UVMS processor and the RS232
Engineers' Terminal port are connected as shown in Figure 10.
Before starting a Factory Self Test, a number of parameters must be entered:
• Lantern type (always amber for UVMS).
667/HB/30325/000 Page 50 Issue 1
SIESIGN 150 H ANDBOOK
• Sign size (number of rows and number of columns).
• Test duration (in hours).
• Cycle time (in minutes).
• Setting time (in seconds).
A maximum value of 255 applies to all these fields.
The ‘Test duration’ parameter defines the overall time for the test to run. If the operator enters 0 for this parameter, the sign runs the test cycle once only.
The ‘Cycle time’ parameter defines how often each cycle is to run during the self test, i.e. the gap between each test cycle. This value must be at least five times the ‘setting time’.
The ‘Setting time’ parameter defines how long each display remains set on the sign.
The ‘Lantern type’ parameter defines which lanterns are tested (red, amber or both).
The lantern test requirement is set by means of two check boxes, one for red lanterns and one for amber lanterns. Only the box for ‘amber lanterns’ should be checked.
All the parameters contain default values when the dialog box is first displayed. These values may be used or replaced.
In addition to the parameters entered, the system obtains the date on which the test is started from the PC and this is added to the parameter list automatically.
The sign size is validated before the test is started and the operator is informed if the size entered is different from that configured in the sign.
The Factory Self Test operates in cycles, each consisting of a set of pre-defined tests.
In between cycles, the sign does not display anything and the sign appears to be inactive. The test cycle runs as many times as the overall test duration time allows.
Each display that is part of the test (including the lantern test) remains set for the duration of the ‘Setting time’ parameter.
When all parameters have been entered, select the ‘Start’ button to start the test running. Once this has been done, the option may be exited and it is possible to continue working on other options or applications or to disconnect the terminal from the sign.
All faults detected are logged and counted.
The Factory Self Test may only be interrupted between test cycles and the Self Test
Results obtained using the Report Factory Self Test Results option, (See Appendix
A4.5.3). However, a report obtained at this time will obviously be incomplete and contain only the results so far.
It is possible to stop the Factory Self Test in between test cycles using the Stop Self
Test option (See Appendix A4.5.2).
667/HB/30325/000 Page 51 Issue 1
SIESIGN 150 H ANDBOOK
The Factory Self Test stops automatically at the end of the test duration time.
Stop Self Test
This facility enables the operator to stop a Factory Self Test before it has completed.
Select the ‘Stop’ button to stop the test or ‘Continue’ to continue.
Note: Any commands selected during a Factory Self Test will only be accepted if they are sent between test cycles, i.e. while the Sign is Blank.
Report Factory Self Test Results
This facility provides a report of the results of the Factory Self Test obtained from the sign. It may be invoked both during a Factory Self Test and after a Self Test has run to completion.
The report is similar to the fault log report but it also contains a count of occurrences of each fault. It also contains the Device Mod Code and Issue State of the sign together with the self test parameters that were used to start the test. The report is displayed in a dialog box.
This report may be saved to a data file by selecting the ‘Save’ button; enter a name for the file in which to store the report. All file names are subject to the usual MS-DOS limitations. The system checks the entered file name and, if it already exists in the system data file directory, flags an error; it is not possible to overwrite an existing file with the same name. The path for the Diagnostics Terminal data file directory is
\DATFILES, which is contained in the installation directory.
Print Self Test Results
This facility is provided specifically to make it easy for the operator to obtain a print out of Factory Self Test Results. However, this facility may be used to print any data files that have been created using the ‘Save’ button in any of the reports.
Test RS485 Link
9600 Baud (Not applicable to UVMS signs)
This facility enables the operator to test the Sign Driver RS485 Link (9600 baud) at the
Sign Enclosure. Once a test is started, a single test message is sent down the link and the software waits for the corresponding reply. The result is displayed as PASS or
FAIL. For security reasons this option is protected by two passwords. If a password has already been entered during the current session, only the second password is required.

This exits the current Diagnostic Terminal application. The exit function must be confirmed. If confirmed the Terminal tries to establish a disconnect with the UVMS
Sign. Only if the disconnect message is replied to correctly does the Diagnostic
Terminal Application terminate.
A.2ERROR MESSAGES
The following is a list of error messages likely to be encountered, where they are likely to be encountered and a brief description of their likely cause.
Unable to Establish a Connection
The Diagnostic Terminal has not received a reply from the UVMS Sign to its connection request messages. Check that the computer is connected to the Sign and to the correct port.
Unable to Disconnect from the VMS Sign
The Diagnostic Terminal has not received a reply from the UVMS Sign to its disconnection request messages. Check that the Sign is still running and that the computer is connected to the Sign and to the correct port.
Error in TIME
RT Clock - either the ‘hours’ field contains a value greater than 23 or the ‘minutes’ field contains a value greater than 59.
Faulty Comms reception - sign driver reply corrupted
Most facilities - this usually means that the terminal is not properly connected to the sign.
File with entered name already exists - Please re-enter file name
Reports (when the ‘Save’ button has been selected and a name for a new file to be created entered) - the file name entered has been found in the data directory
\DATFILES.
Invalid entry in DAY field
667/HB/30325/000 Page 54 Issue 1
SIESIGN 150 H ANDBOOK
RT Clock - the value in the day field is either less than 1 or incorrect for the month and year combination, e.g. 31-4-95, 29-2-99.
Invalid entry in MONTH field
RT Clock - the month field contains a value greater than 12 or less than 1.
Invalid Password
All options that are password protected - the password has been entered incorrectly.
Invalid Password - Process Aborted
All options that are password protected - if, after three attempts, the password has still not been entered correctly, this message is displayed and the software then returns to the main menu of the Diagnostics Terminal.
New password and confirm password inconsistent
Set password - the character strings entered in the ‘new password’ field and the
‘confirm password’ field do not match; enter the new password in both of these fields
before selecting the ‘OK’ button.
Number of characters or number of rows is incorrect for configuration
Start Factory Self Test - the sign size is configured in the sign; this message appears if the values entered in the ‘number of characters’ field and/or ‘number of rows’ field are not the same as those in the sign configuration.
Self Test Parameter is greater than 255
One of the parameters entered in starting a factory self test is greater than 255.
Setting time and Cycle time contain inconsistent values - please correct
Start Factory Self Test - each cycle contains a number of pre-defined tests, each of which remains set for the number of seconds entered in the ‘setting time’ parameter; this message is displayed if the ‘setting time’ is such that the test cycle exceeds the cycle time parameter.
Sign Type is EMS - Red lanterns should not be set
Start Factory Self Test - EMS signs do not have red lanterns; this message appears if the terminal is connected to an EMS sign and red lanterns are selected as one of the lantern type parameters.
Stored Message Code entered is out of range
Set EMS - a Stored Message Code (after the ‘#’) which is either greater than 31 or contains a non-numeric character which causes the code to go out of range (between 0 and 31).
Wrong sign type for function
If the terminal is connected to an EMS sign and the operator tries to select the Set EMI option, this message appears.
