Fault Code System Failure
Fault 103
*Postpurge
EEPROM
error*
Postpurge configu-
ration in EEPROM
is not initialized or is
corrupted.
Enter Setup and re-commission Postpurge settings.
If the fault persists, replace the relay module.
Fault 104
*Valve
proving (VP)
configura-
tion error*
Invalid valve proving
configuration detected.
Enter Setup and re-commission Valve proving settings.
If the fault persists, replace the relay module.
Fault 105
*Call Service*
Relay Module self-test
failure.
Reset and sequence the relay module.
If the fault reappears, remove power from the relay module
and
reapply the power; reset and sequence the relay module.
If the fault persists, replace the relay module.
Fault 106
*Relay mod-
ule self-test
failure*
Relay Module self-test
failure.
Fault 107
*Call Service*
Relay Module flame
signal crosscheck
failure.
-
Fault 108
*Unused*
Unused fault -
Fault 109
*Negative
AC cycle
detected*
Negative cycle test
failed, earth ground
absent or line voltage
phasing improper.
Make sure a good earth ground connection exists at the in-
stallation site and all earth ground connections are complete
and correct.
Make sure the relay module and all loads operate at the same
line voltage phase.
Reset and sequence the relay module.
If the fault persists, replace the relay module.
Fault 110
*Locked
jumpers do
not match
configura-
tion*
The configuration
jumpers differ from
stored values.
Inspect the jumper connections. Make sure they match
the original selection and clipped jumpers are completely
removed.
Reset and sequence the relay module.
If the fault persists, replace the relay module.
Configuration jumpers must be selected prior to 200 hours
of operation. If configuration jumpers are changed after 200
hours of operation, lockout 110 occurs. Relay module cannot
be reset and must be replaced.
Fault 111
*Bad jumper
reading*
Relay Module config-
uration jumper test
failure.
Inspect the jumper connections. Make sure they match
the original selection and clipped jumpers are completely
removed.
Reset and sequence the relay module.
If the fault persists, replace the relay module.
Fault
112–126
*Call Service*
Relay Module self-test
failure.
Reset and sequence the relay module.
If the fault persists, replace the relay module
Fault 127
*Call Service*
Safety relay feedback
circuit was in an im-
proper state.
Reset and sequence the relay module.
If the fault persists, replace the relay module.
