Intermediate “IGNITION
TERMINATED” error message
displays.
This error message displays when
the J4 Pin 10 on the motor control
board doesn't receive 12VDC
within 50 seconds of the start of a
heat cycle.
Loose/dirty connections throughout
the gas system. Clean all wire terminals in the gas
system with contact cleaner.
(Service bulletin S2691.) Inspect
all wire terminals and perform tug
test to make ensure proper
connections. If terminals are loose,
tighten the terminals with pliers or
replace them. The main areas to
focus on are the IDC header and
the gas valve terminal block
located on the back left frame post.
Wires broken due to movement.
There might be a short that is only
present when the platen is moving
up or down. Using a meter, check for continuity
through all the wires in the gas
system. Inspect all wire routing to
ensure it is not tied to the wires
from the upper platen.
Low gas pressure to unit. Measure the output gas pressure
from each gas valve. The site's
gas pressure will have to be
adjusted. This is the responsibility
of the site.
The combustion ratio is incorrect. Measure the CO/CO2 with the
combustion meter and adjust per
combustion meter instructions.
Electrode grounding. Check continuity of the ground
wire. If there's no continuity,
replace the wire.
