Lamp Monitoring

Lamp monitoring is now performed internally by the controller’s main processor, no

other cards are required and very little, if any external wiring is required.

The lamp monitor is automatically configured from the configuration PROM and will

be ready to learn the lamps of the junction.

Should the lamp monitor need resetting explicitly, then ‘KLR=1↵’ should be entered.

Before leaving a controller, the lamp monitor should be checked to ensure that it has

learnt the junction, i.e. that it has been given time to confirm exactly how much

current flows for each phase and colour.

This can be achieved by entering ‘KML↵’. This command automatically cycles

through all the phases and colours which the lamp monitor has not yet learnt,

resulting in displays of the following format:-

KML:LMU Disabled

Lamp monitoring has not been enabled in the configuration.

KML:A/Red 0%

Phase A red is 0% learnt, i.e. the lamp monitor has not

seen phase A red illuminated.

KML:A/Green 50%

Phase A green is 50% learnt, i.e. the lamp monitor has

learnt in the current in either dim or bright but learning is not

complete until the lamp monitor has learnt the current in

both states.

KML:A/Amber 25%

Phase A amber is 25% learnt, i.e. the lamp monitor has

started to learn the current but the colour has not yet been

illuminated for long enough.

KML:Awaiting D/B

The lamp monitor has finished learning all the currents in

the present dim or bright state and is waiting for a change to

the other state in order to complete the learning process.

KML:A/Red 100%

The lamp monitor has completely learnt phase A red.

KML:S33/A1 0%

The external optional sensor number 33, aspect pattern 1

has not yet been learnt. Most configurations will be

defaulted to provide two spare sensors which can be used

to monitor regulatory signs. If no signs are fitted, then the

lamp monitor will happily learn zero current when the

signals are bright after a short delay.

KML:Complete

Learning is complete, i.e. the lamp monitor has successfully

learnt all of the currents of the junction.
