Table 4-2: Fault Messages - Continued
FAULT MESSAGE FAULT DESCRIPTION
IGNITION SPARK FAULT The spark detector sensor did not detect spark current during the
ignition cycle.
CLEANING IGNITER This is a notice that the igniter cleaning cycle is occurring.
TOO MANY CYCLES IN
24 HOURS
This is a warning of high cycling. The period is a 24 hour cycle
based on time of day.
TOO MANY OVRTMPS IN
24 HOURS
This is a warning of excessive over temperature conditions. The
period is a 24 hour cycle based on time of day.
AIR SENSOR FAULT The temperature measured by the inlet air temp sensor is out of
range.
FAULT ACTIVE A fault has occurred and the display is being updated to indicate
the specific fault.
4.2.1 Airflow Fault During Purge (On Units Less Than 2.5 Million
BTUs)
If an Airflow Fault During Purge fault is encountered, The C-More will attempt one re-ignition
sequence. If the fault persists on the second successive try, the C-More will go into a Hard Fault
mode requiring operator intervention.
The Ignition Retry Sequence for Airflow Fault During Purge consists of the following actions
and displays:
1. WAIT RETRY PAUSE - A 30 second pause before another trial is attempted.
2. WAIT IGNITION RETRY – This is the standard Ignition Sequence
Any Ignition failure due to Airflow Fault During Purge will be recorded in the C-More Fault Log,
even if it is followed by a successful Ignition Retry.
4.2.2 Flame Loss During Ignition (On Units Less Than 2.5 Million
BTUs)
If a Flame Loss During Ignition fault is encountered, The C-More will attempt a re-ignition
sequence. If the fault persists on the second successive try, the C-More will go into a Hard Fault
mode requiring operator intervention.
The Ignition Retry Sequence for Flame Loss During Ignition consists of the following actions and
displays:
1. WAIT RETRY PAUSE – A 30 second pause before another retry is attempted.
2. WAIT IGNITION RETRY – This is the standard ignition sequence.
Any Ignition failure due to Flame Loss During Ignition will be recorded in the C-More Fault Log,
even if it is followed by a successful Ignition Retry.
