FLF ABBR FLD Description

RLAY

3 Relay Tests Failed:

The relay tests try to detect short-circuits while the controller

is operating normally with the lamp supply on. By closing all

but the relay under test, the lamp supply should not be

present unless that relay is short circuit. Note that if any

relay is stuck open circuit, then the lamp supply fault (FLF17)

will detect no lamp supply.

The fault log data will indicate the detected fault:

FLD 1:00000001 - Relay A appears to be short circuit

FLD 1:00000010 - Relay B appears to be short circuit

FLD 1:00000100 - SSR appears to be stuck short circuit

Note that the test on the SSR may fail if there are no lamps

connected to the controller.

CFT

50-65 Green Conflict Detected:

This fault indicates that the main processor detected a green

conflict in the lamp states it requested. The first 4 bytes

show the conflicting phases.

FLD 50:01000100 - Conflicting phases A-H

FLD 51:00000000 - Conflicting phases I-P

FLD 52:00000000 - Conflicting phases Q-X

FLD 53:00000000 - Conflicting phases Y-F2

The next 12 fault data bytes show the requested lamp

states:

FLD 54:00111001 - Requested reds A-H

FLD 55:00100010 - Requested ambers A-H

FLD 56:11000100 - Requested greens A-H

FLD 57:11100000 - Requested reds I-P

...through to...

FLD 65:00000000 - Requested greens Y-F2
