Table 8. Hold and Fault Message Summary.
Purge card problem.
Lockout due to inability to take minimum number of samples.
Lockout due to AC line dropout detected.
Lockout due to AC line frequency too fast.
Lockout due to insufficient AC line voltage.
Purge card parity is bad.
Flame sensed when checked for ampli-check system.
Flame sensed when checked for shutter-check system.
Flame detected during Standby and time limit has expired).
Preignition interlock open during Standby and time limit has expired.
Airflow switch shorted and limit has expired in Standby (demand was present)
High Fire switch open and time limit has expired during prepurge.
Flame sensed when shutter open and no flame is expected during Standby.
Main flame failure during Run after flame has been on for a while.
Flame detected during Purge or Waiting, when no flame should exist.
Flame loss detected, main flame did not ignite or failed during first 10s of Run.
Low Fire switch open and time limit has expired during Waiting.
Combustion airflow interlock fault during Waiting.
Flame interlock is enabling fuel valves and no flame is present.
Flame interlock feedback indicates it is not enabling main valve.
Pilot flame failure.
Low fire interlock switch failure to close during Run.
Airflow switch failed to make or opened.
Preignition interlock opened.
Safety relay feedback showed off when it should be on.
Main valve relay feedback showed off when it should be on.
Pilot valve relay feedback showed off when it should be on.
Ignition relay feedback showed off when it should be on.
Pilot valve 2 relay showed off when it should be on.
Safety relay feedback showed on when it should be off.
Main valve relay feedback showed on when it should be off.
Pilot valve relay feedback showed on when it should be off.
Ignition relay feedback showed on when it should be off.
Pilot valve 2 relay feedback showed on when it should be off.
Low fire switch opened.
Type and/or FFRT has changed since initial read.
Field jumpers have changed since initial read.
Illegal jumper combination selected (as defined by the burner sequence).
Measured flame signal is to strong.
Pilot valve 2 relay feedback showed off when it should be on.
