Action
Warning Communications with option board #1
has been lost.
Warning Communications with option board #2
has been lost.
Warning Communications with option board #3
has been lost.
Warning Communications with option board #4
has been lost.
Shutdown The ECM shutdown the engine and
reported low oil pressure as the fault.
Warning The ECM reported a high voltage error
for the oil pressure sensor.
Warning The ECM reported a low voltage error
for the oil pressure sensor.
Shutdown The controller shut down the generator,
and ceased cranking, because the
engine was not successfully started
after the completion of the last of the
crank cycles setting delay 15 seconds.
Warning Ignition coil 1 voltage is below normal or
there is an open circuit.
Warning Ignition coil 1 voltage is abnormal.
Warning The controller has lost communications
with a PIM, or load management device
that had previously been
communicating properly.
Shutdown The controller, or the ECM, shutdown
the generator because the speed signal
was lost.
Shutdown The controller shut down the generator
[
because the voltage measured from
Phase A to Phase B exceeded the high
limit for a time greater than the delay
setting 2 seconds.
Shutdown The controller shut down the generator
[
because the voltage measured from
Phase A to Phase B was greater 5% of
rated, but less than the low voltage
setting for a time greater than the delay
setting 10 seconds.
