EMERGENCY SHUTDOWN PROCEDURE
NOTICE
The Emergency Stop switch should only be used
to stop the engine in case of an emergency or to lock
out operation during service. The Emergency Stop
switch should NEVER be used for routine stopping of
the engine.
1. To stop the engine in the event of an emergency, press
the Emergency Stop switch (Figure 61), located on
the side of the generator next to the output terminal
panel.
Figure 61. Emergency Stop Switch
2. Place the main, auxiliary, and GFCI circuit breakers
in the OFF position as shown in Figure 58.
3. The emergency stop switch is a push-locked type switch.
The switch contact can only be released by rotating
the button in the clockwise direction. The engine can
not be restarted until the contact is released (closed).
AUTOMATIC SHUTDOWN SYSTEM
This unit is equipped with safety devices that will
automatically shut down the engine in the event of low
oil pressure (approximately 14 psi / 97 kPa), high water
temperature (approximately 212°F/100°C), or over speed
(approximately 2,040 rpm). The alarm lamps on the ECU
will illuminate to signify the reason for the shutdown.
NOTICE
Before inspecting the generator after an automatic
shutdown, place the Auto Start/Stop switch in the
OFF/RESET position, and place all circuit breakers in
the OFF position. Allow adequate time for cooling before
troubleshooting. When all faults have been cleared,
restart the engine according to the Generator Startup
Procedure section of this manual.
