Operator`s manual

General
This manually-controlled series of
Westerbeke marine diesel gener-
ators is equipped with toggle
switches on the engine's control
panel and, optionally, at remote
panels. The following instructions
and methods
of correcting minor
problems apply only to such toggle
switch controls.
All three switches are momentary
contact type and serve the follow-
ing functions:
1. PREHEAT: The PREHEAT tog-
gle switch is a double-pole, single-
throw switch. The switch serves
two purposes: preheating the
engine for easy starting and defeat-
ing
or bypassing the engine's pro-
tective oil pressure sensor. The
defeat function turns on the fuel
solenoid, instrument power, alter-

nator excitation and provides power to the START switch.
2. START: The START toggle switch is a double-pole, single-throw switch. The switch, when
activated, energizes the starter solenoid for starting the engine. This switch will not operate electrically
unless the
PREHEAT switch is depressed and held at the same time.
3. STOP: The STOP toggle switch is a sinle-pole, single-throw, normally-closed switch. This switch
provides power to the fuel solenoid, instrument cluster and alternator excitation, after the oil pressure
switch has closed upon starting. Opening of this switch opens the power circuit to the fuel solenoid, thus
stopping the flow
of fuel to the engine and stopping the engine.
4. In addition to the three switches above, the Standard Instrument Panel used with Westerbeke diesel
generator sets includes two gauges, which indicate water temperature in degrees Fahrenheit (WATER
OF)
and oil pressure in pounds per square inch (OIL PSI), and two meters, which indicate DC control circuit
voltage
(VOLTS) and generator running time (ELAPSED TIME) in HOURS and 1110 hours. The Water
Temperature and
Oil Pressure gauges, and the DC Voltmeter are illuminated; the ELAPSED TIME meter
is not.
