INSTRUMENT CONTROL PANEL
INSTRUMENTS
COOLANT TEMPERATURE GAUGE
Engine coolant (water) temperature should normally indicate
175
0
to 195
0
F (80
0
to 90
0
C).
ENGINE OIL PRESSURE GAUGE
Oil Pressure (psi) may fluctuate depending on the generator
load but should range between
30 to 60 psi.
DC VOLTMETER GAUGE
Indicates the amount the battery is being charged and should
show 13V to
14Y.
HOURMETER GAUGE
Registers elapsed time and is used as a guide for when to
perform scheduled maintenance.
TOGGLE SWITCHES
All three switches are momentary contact type.
EMERGENCY STOP SWITCH
The emergency stop switch on the side of the
control box is normally closed. When
depressed, it will open the DC circuit to the
control panel and shut the engine down.
As the switch is not toggled it can
be used
when performing maintenance.
8 AMP FUSE
An 8 amp fuse protects the instrument panel
from an electrical overload.
It is important to closely monitor the panel gauges.
Become aware
of the 1lonnal engine readings and take
immediate action
if these readings start to vary.
STARTING
PREHEAT: The PREHEAT toggle switch serves two purposes:
preheating the engine for easy starting and defeating
of
bypassing the engine oil pressure switch. The defeat function
activates the K2 relay instrument power fuel pump and fuel
solenoid hold terminal.
When the
PREHEAT switch is depressed, the voltmeter,
panel lights, gauges and meters and fuel solenoid will
activate.
START: The START toggle switch closes the Kl relay that
energizes the starter solenoid and activates the starter.
While the
PREHEAT switch is still depressed, depressing the
START switch engages the strut solenoid. When the engine
begins to fire, the
START switch should be released. The
PREHEAT switch should not be released until the oil
pressure reaches 5 -
10 psi.
Should the engine not start when the START switch is
depressed for 10 to 20 seconds, release both switches and
wait
30 seconds. repeat the procedure above and preheat
longer. Never run that starter
for more than 30 seconds.

NOTE: When starting:
A voltage drop will occur
when the preheat switch
is depressed.
Once the engine starts, check the engine's instruments for
proper oil pressure and battery charging voltage. Apply a
light load to the generator and allow the engine's operating
temperature to come up to
140
0
- 150
0
F (60
0
- 66
0
C) before
applying heavy loads.
NOTE: Some unstable running may occur in a cold engine.
Depressing the PREHEAT button
for 10- 15 second
intervals will help stabilize the engine rpm until the
operating temperature reaches
140° -190°F and a load is
applied to the engine.
STOPPING
The STOP toggle switch is a normally closed switch,
providing power to the K2 relay, after the oil pressure
switch has closed upon starting. Opening
of this switch
opens the K2 relay power circuit to the fuel solenoid,
stopping the flow
of fuel to the engine and shuts down
the engine.
To stop the engine, depress the
STOP switch. When the
STOP switch is depressed, the power feed to the fuel
solenoid is opened, and the fuel flow to the engine is
stopped. The
STOP switch should be depressed until the
generator stops rotating.
NOTE: When the engine is shut down, the water temperature
gauge and the oil pressure gauge will continue to register the
last temperature
and oil pressure readings displayed. They
will return to zero once electrical power is restored.
