Operating Procedures The engine–generator controller is designed to start and stop an engine from either a local
(“Manual”) or remote (“Automatic”) mode. When a start command is issued, the controller issues
a run and crank output signal. The controller then monitors engine speed and when crank
disconnect speed is reached, the crank signal is terminated. While the engine accelerates to
normal speed, the controller continuously monitors the engines speed signal. Should the engine
speed exceed the maximum predetermined setpoint, the overspeed shutdown fault circuit will
activate, terminating the run signal.
In addition to overspeed shutdown, the engine controller also monitors many other engine
protection circuits and should they be activated, the engine will be stopped and/or alarm initiated.
The engine will automatically stop for any shutdown condition, or when the remote and/or local
start signal is removed. The engine controller operation includes time delay circuits for normal
operating conditions such as start delays, cool down and cranking periods.
