System Failure
No card is plugged into the purge card slot or purge card was removed
during operation.
Excess noise or line frequency is below acceptable tolerances.
AC line momentarily interrupted.
Line frequency is faster than expected value.
AC line voltage is below accepted value (loss of amplitude or brownout).
Damaged purge card is plugged in or purge card value has changed since
purge card was initially read.
Flame signal was not detected when flame signal should have been present for a
standard amplifier.
Flame signal was detected where no signal should be present for shutter-check
system (Shutter Test).
Flame sensed when shutter opened and no flame is expected during STANDBY.
Preignition Interlock fault during STANDBY.
High Fire Interlock Switch failure to close during PURGE.
Flame sensed when shutter opened and no flame is expected during PURGE.
No flame time exceeded limit during Pilot Flame Establishing Period with
Run/Test Switch in TEST position.
Main flame failure during RUN after flame has been on for ten seconds.
