Action
SD Measured load is greater than 102% of
the generator set power rating for more
than 1 minute. (38RCL only)
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.
Shutdown The controller shut down the generator
[
because the voltage measured from
Phase B to Phase C 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 B to Phase C was greater 5% of
rated, but less than the low voltage
setting for a time greater than the delay
setting (default 10 seconds).

Description/ Comments Check
Reduce the load by
disconnecting non-essential
equipment. Check wiring and
troubleshoot connected
equipment.
Check for phase imbalance.
Check for very high power
factor loads.
