Installation manual

STARTING/STOPPING PROCEDURE
STARTING UNDER COLD CONDITIONS
Make sure the lubricating oil conforms with the ratings for
the prevailing temperature. Check the table in the ENGINE
OIL section in this manual.
The battery should be fully charged to minimize voltage
drop.
Use a sufficient amount of preheat to aid in starting. See the
Temperature/Preheat chart on the previous page.
STOPPING PROCEDURE .
1. Remove the AC electrical load from the generator and
allow the
generator·to run for three to five minutes to
stabilize its operating temperatures.
2. Depress the STOP switch and hold it until the generator
is completely stopped.
3. Now release the STOP switch.
Remote Stopping Procedure
To stop the generator, depress the STOP switch which opens
the normally closed B+ path for voltage to the engine's run
·circuit. The STOP switch must be held open until the
generator comes to a complete stop and the green LED light
goes out.
SAFETY SHUTDOWN SWITCHES
The engine is protected by three automatic shutdown
switches. Should shutdown occur,
do not attempt to restart
without
finding and correcting the cause. Refer to the
heading "Engine Stops" in the TROUBLESHOOTING
section of this manuaL
'The following is a description of these automatic shutdown
switches:
High Exhaust Temperature Switch
An exhaust temperature switch is located on the exhaust
elbow. Normally closed, this switch will open and interrupt
the DC voltage to the K2 relay (shutting
OFF the engine) ·
should the switch's sensor indicate an excessive exhaust tem-
perature (an inadequate supply
of raw water causes hjgh
exhaust temperatures). This switch opens at 260-270°F (127-
1320C). This switch resets at approximately 225°F (107°C).
9
Coolant Temperature Switch
A! high coolant 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 K2
relay, thereby shutting off the engine. This switch resets at
195°F
(107°C). .
Low Oil Pressure Switch
THERMOSTAT
ASSEMBLY
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 K2 relay, ther~by shutting off the engine.
OIL PRESSURE SWITCH
OIL PRESSURE
SENDOR
Engine Circuit Breaker
The generator's engine is protected by an engine mounted
manual reset circuit breaker (20 amps DC). Excessive current
draw or electrical overload anywhere in the instrument panel
w
1
iring or engine wiri~g will cause the breaker to trip. In this
event the generator wtll shut down and the voltage to the
K2
relay is terminated. If this should occur, check and repair the
source
of the problem. After repairing the fault, reset the
breaker and restart the generator.
