MANUAL STARTER DISCONNECT (TOGGLE SWITCHES)
GENERAL:
This manually controlled series of Westerbeke marine diesel generators
is equipped wi th
toggle
swi tches on
the eng ine 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 following
functions:
1.
Preheat:
The PREHEAT/DEFEAT toggle switch is a double pole,
single throw swi tch.
The swi tch serves two purposes: pre-
heating
the
engine
for
easy
starting
and
defeating
or
bypassing
the engine protective oil pressure
switch.
The
defeat function acti va tes the fuel run solenoid, instrumen-
tation,
alternator
excitation,
electric
fuel
pump
and
supplies DC voltage to the start switch.
2.
Start:
The START
toggle switch
is a double pole,
single
throw swi tch.
The swi tch, when depressed, supplies 12 volt
DC power to the starter solenoid, energizing the starter to
start the engine.
3.
Stop:
The STOP toggle switch is a single pole, single throw,
normally closed swi tch.
This swi tch provides power to the
fuel run solenoid, instrument cluster and alternator excita-
tion, after the oil pressure switch has closed upon starting.
Opening of this swi tch opens the power circui t
to the fuel
run solenoid, thus stopping the flow of fuel to the engine
and stopping the engine.
ENGINE OPERATION:
1.
Preheat:
Depress the PREHEAT switch.
This will activate the
instrument panel gauges and lights.
The fuel run solenoid
will
be
activated,
drawing
the
throttle
arm
into the run
position.
The preheat solenoid will close and supply voltage
to the glow plugs.
The electric fuel pump will be activated.
Hold the preheat switch depressed 15 to 60 seconds, depending
on ambient temperature.
2.
Start:
Continuing
to
hold
the PREHEAT
switch depressed,
depress
the START switch.
This will energize the starter
solenoid,
engag ing
the
star t.
Once
the
eng ine
f ires and
star ts to run,
release the START swi tch only.
Continue to
hold
the
PREHEAT
switch
depressed
until
the
engine
oil
pressure reaches 25 PSI, then release it.
3.
Stop:
Depress the STOP switch and hold it until the engine
stops completely.
