ST800 Guidance Notes

When learning is complete, the learnt load for each sensor and aspect, i.e. each

phase and colour, can be displayed using ‘KEL↵’.

For example, if there are three signal heads connected to phase A, each fitted with

50W halogen lamps, then entering KEL would display the following assuming 5W for

the transformers in the signal heads:

Keystrokes Display

KEL↵

KEL 1 0:167W A/Red

KEL 1 1:164W A/Green

KEL 1 2:165W A/Amber

KEL 2 0:166W B/Red

etc...

The format of the command is as follows, KEL s a:nnnW p/ccccc, where:

‘s’ = sensors 1 to 32 monitor A to F2, sensors 33 to 48 are external

‘a’ = aspect (or colour) pattern identifier

‘nnn’ = the load that has been learnt, i.e. the watts normalized to 240V

‘p/ccccc’ = phase and colour associated with this sensor and aspect pattern

When a lamp fault is detected, the fault log flag FLF 55 is set and more information

can be displayed using ‘KLD↵’. For example if one of the 50W green lamps on

phase A failed, then the following would be displayed:

Keystrokes Display

KLD↵

KLD 1 0:52W A/Green

KLD END OF LOG

After the lamp has been replaced, the lamp monitor will automatically clear the fault

once it has been given time to confirm the replacement. Note that the default confirm

time is 10 seconds.

If ‘KLD’ indicates that a lamp has failed, but all the lamps appear to be working

correctly, check that ‘KEL’ for the same sensor and aspect numbers displays a learnt

load which matches the number of lamps connected.

To clear any such lamp faults, view the KLD lamp fault entry as normal and simply

type ‘=0↵’ to change the ‘failed’ wattage back to zero. Note that this operation

requires level 3 access. Also note that this cannot be used for failures on vehicle red

lamps used for red lamp monitoring, any such attempt will result in the error ‘*W’.

Alternatively, the lamp monitor can be reset and all the lamp loads relearnt by

entering ‘KLR=1’.
