A control panel unit mounted on the generator end of the set shall be provided for the start-up, monitoring, and protection of the generator set. The control panel shall include a run-stop-remote switch to permit local testing of the set, the voltmeter and ammeter (with selector switches), the frequency meter, the run time meter (nonresettable type), the cranking control system, the automatic voltage regulator, the exciter circuit breaker, gauges for oil pressure and coolant temperature, and a solid state engine monitoring system.

The cranking cycle shall consist of a 15-second “on”/15-second “off” cycle for three attempts. If the engine fails to start, the cranking control system shall be locked out and an overcrank shutdown alarm shall be initiated. The engine shall also be shut down and locked out upon encountering overspeed, low lubrication oil pressure, and high engine temperature conditions.
