Exercise Not Scheduled. No exercise has been
scheduled on the RDC2 controller.
Governed frequency exceeds 110% of the
system's frequency setpoint for more than 10
seconds. Function becomes active 10 seconds
after engine start (10 second inhibit).
Governed frequency falls below 90% of the
system frequency setting for more than
10 seconds, or 1 Hz below the system frequency
setting for more than 60 seconds.
Function becomes active 10 seconds after
engine start (10 second inhibit).
Generator Voltage High. Output voltage
exceeds 120% of the system nominal voltage for
more than 2 seconds.
Generator Voltage Low. Output voltage falls
below 80% of the nominal system voltage for
more than 10 seconds.
Low cranking voltage. Battery voltage falls
below 60% of system battery voltage for more
than 6 seconds while the starter is engaged.
No engine rotation is sensed during cranking.
Shuts down 3 seconds after the fault is detected.

mode. Remote start and stop commands from a
transfer switch or remote switch will be ignored.
Three unsuccessful starting attempts.
Engine speed sensor has failed or engine
stalled.
Measured load is greater than 102% of the
generator set power rating for more than 1
minute. (38RCL only)
