The Handset can also be used to set the Real Time Clock using Level 3 access and

7.4.9 Lamp Testing
The ability to test individual lamps is an important facility that allows faults to be
identified easily and rectified. The inbuilt self-test facility can be used to illuminate
each aspect in turn or the lamp test facility that allows individual aspects to be
illuminated is provided via the web page:
Status and Configuration → Controller → Phases → Lamp Test
To use this facility level 3 access is required and the signals on/off switch MUST be
in the OFF position.
Use with Care!
All aspects under test must be covered
The aspect to be tested is identified and the following information entered into the
web page:
• Phase
• Aspect Colour
• Duration of Test in seconds
• Once this information has been entered, press the 'Submit' and 'Confirm'
buttons to start the test. The remaining time for the test is displayed against
'Progress'.
• The RS232 Handset 'LMP' command can also be used for lamp testing.
7.4.10 Learning Lamp Loads
When a new configuration is loaded or lamp loads are added or removed the lamp
monitoring system will need to learn the connected loads. This can be achieved
through Level 3 access and the web page:
Status and Configuration → Controller → LMU → Reset
If red lamp faults have extinguished phases, always attempt a 'Red Lamp Fail Reset
Request' before attempting a 'Full Lamp Monitor Reset Request'.
Select the appropriate action and select 'reset' and then press the 'Submit' then
'Confirm' buttons.
To help with the learning sequence, artificial demands can be inserted along with a
forced Dim/Bright change to ensure that all loads are learnt.
Use with Care!
Dim signals may be difficult for road users to see during daylight hours
Inserting artificial demands may confuse road users
