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
tog-
gle 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: preheat-
ing the engine
for
easy starting
and defeating
or
bypassing the
engine's protective
oil pressure
sensor. The defeat

turns on the fuel solenoid, instrument power, alternator excitation and provides power

2.
SIABI:
The STARTtoggle switch is a double-pole, single-throw switch. The switch, when activated, ener-
gizes 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..sIQE.:
The STOP toggle switch is a single-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 gen-
erator sets
includes
two
gauges, which indicate water temperature in degrees Fahrenheit (WATER 0
F)
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 1/10 hours. The Water
Temperature and
Oil Pressure gauges, and the DC Voltmeter are illuminated; the ELAPSED TIME meter
is not.
