SAFETY SHUTDOWN SWITCHES
SAFETY SHUTDOWN SWITCHES
The generator is protected by three automatic shutdown
switches. Should shutdown occur,
do not attempt to restart
without finding
and correcting the cause. Refer to the
ENGINE TROUBLESHOOTING section of this manual.
The following is a description of these automatic shutdown
switches:
High Water Temperature Switch
A high water temperature switch is located on the thermostat
housing. Normally closed, this switch, should the fresh water
coolant's operating temperature reach approximately
210°F
(99°C), will open and interrupt the DC voltage to the fuel
solenoid on the injection pump, thereby shutting off the
engine. This switch resets at 19SOF (107°C).
Engine Circuit Breaker
The generator's engine is protected by an engine mounted
I manual reset circuit breaker (20 amps DC). Excessive current
! draw or electrical overload anywhere in the instrument panel
wiring or engine wiring will cause the breaker to trip. In this
event most generators will shut down because the opened
breaker disconnects the fuel supply.
If this should occur,
; check and repair the source
of the problem. After repairing
the fault, reset the breaker and restart the generator.
Low Oil Pressure Switch
A low oil pressure shutdown switch is located off the
engine's oil gallery. Normally
open in a static state, this
switch's sensor monitors the
engine's oil pressure. Should
the engine's oil pressure fall to 5-10 psi, this switch will
open interrupting the DC voltage to
the fuel solenoid on the
injection pump, thereby shutting
off the engine.
