Control Panels

1. SHUTDOWN BYPASS-PREHEAT SWITCH
Two functions are built into this switch: the preheating
of the engine, and bypassing of the engine safety shut-
down circuit. Hold switch in the ON position
10 - 20 seconds before starting the engine, and continue
holding on during engine cranking. Release the switch
as soon as the engine is running. Holding the switch on
too long can burn out the heater element.
2. ENGINE CONTROL SWITCH
To start the engine, hold this switch in the START
position until the engine is running.
NOTE: Excessive cranking of marine sets equipped
with water lift muffler systems can cause engine damage.
See page 7.
After the engine starts, release the switch and it will
return to RUN position. To stop the engine, hold the
switch in the STOP position until the engine has
completely stopped.
NOTE: The rocker switch is used on Series 1 panels only,
and has a light that glows when the set is running.
3. HOUR METER
Keeps track of engine running time.
4. OIL PRESSURE GAUGE
Shows the oil pressure in the engine lubricating system.
5. ENGINE TEMPERATURE GAUGE
Registers the temperature of the engine coolant.
6. D.C. VOLTMETER OR AMMETER
When the engine is stopped, the voltmeter indicates the
condition of the battery. When the engine is running, the
voltmeter indicates the voltage output of the alternator.
For Series 4 Control Panels Only:
7. A.C. VOLTMETER
Shows the generator output voltage.
8. FREQUENCY METER (Hertz)
The frequency meter indicates alternating current
frequency: 60 Hz (1800 RPM), or 50 Hz (1500 RPM).
9. AMMETER/VOLTMETER SELECTOR SWITCH
Used to check voltage and current of each phase.
10. A.C. AMMETER
Shows the generator load on each phase. The phase is
selected with the Ammeter Selector switch (
OM843NW3 11/13
