Overcrank Shutdown - Guardian 5240 Diagnostic Repair Manual

SECTION 1.5
ENGINE-GENERATOR PROTECTIVE DEVICES

OVERCRANK SHUTDOWN

This feature prevents the generator from damaging
itself when it continually attempts to start and another
problem, such as no fuel supply, prevents it from start-
ing. The unit will crank and rest for a preset time limit.
Then, it will stop cranking, and the LED on the gen-
erator control panel will light indicating an overcrank
failure. The AUTO/OFF/MANUAL switch will need to
be set to OFF and then back to AUTO to reset the
generator control board.
NOTE: If the fault is not repaired, the overcrank
feature will continue to activate.
