The control has held for more than 10 minutes waiting for the low fire switch
(M-D) to close.
The running interlock circuit (3-P) has opened during the pilot trial for ignition
period. Applies to non-recycle programmers only.
The running interlock circuit (3-P) has opened during the main trial for ignition
period. Applies to non-recycle programmers only.
The running interlock circuit (3-P) has opened during the main burner on period.
Applies to non-recycle programmers only.
Flame has been sensed during the burner off time (term. L1-13 open) or during the
purge period for sixty (60) seconds.
A flame failure occurred during the pilot trial for ignition period.
A flame failure occurred during the main trial for ignition period.
A flame failure occurred during the main burner on period.
This message appears because of ignition cable noise. Reroute scanner wires away
from high voltage ignition cables. Check for proper spark gap or cracked porce-
lain. Check for proper grounding of wiring base and power supply. Replace worn
ignition cable and/or faulty connections.
Excessive current or short circuit detected on terminals 5, 6, or 7 during PTFI,
MTFI, or Auto. The control will lockout upon sensing this condition on two con-
secutive cycles.
During pilot trial for ignition period, voltage sensed on terminal 7 is different from
the previous cycle. (e.g.: jumper added or removed between term. 7 and 5 or 6).
Electrical noise detected on terminals L1 and L2.
A power interruption to terminals L1 and L2 has caused the control to lockout.
Applies to EP165 programmer only.
