Generator Control Panels - Westerbeke 8.0 BTD Operator's Manual

GENERATOR CONTROL PANELS
DESCRIPTION OF SWITCHES
Thls manually controlled ,series of WES1ERBEKE marine
diesel generators is equipped with toggle switches on the
engine control panel and, optionally, at remote panels.
All three switches are momentary contact type and serve the
following functions:
PREHEAT: TI1e PREHEAT toggle switch serves two purposes:
preheating the engine for easy starting and defeating of
bypassing the engine oil pressure switch. The defeat function
turns on the fuel solenoid . . instrument power and alternator
excitation.
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 start 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.
STOPPING:
The STOP toggle switch is a nonnally closed
switch a DC path through the three automatic shutdown
switches to the K2 run relay. Opening this switch termi-
nates this DC path to the K2 run relay shutting down the
engine.
To stop the engine, simply depress the STOPswitch. The
DC path to the K2 run relay is terminated, de-energizing
the relay and the engine shuts down. The STOP switch
should be held depressed until the generator shuts down
completely.
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 press we readings displayed. They
will retwn to zero once electrical power is restored.
EMERGENCY STOP: 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
~he
switch is not toggled
it
can be used when
petforming maintenance.
DESCRIPTION OF GAUGES
Coolant Temperature
Engine coolant (water) temperature should normally indicate
175° to 195° F (80° to 90°
C).
Engine Oil Pressure
Oil pressure (psi) may fluctuate depending on the generator
load but should range between between 30 to 60 psi.
DC Voltmeter
Indicates the amount the battery is being charged should show
13.5V
to
14.4V. .
Hourmeter
Registers elapsed time and is used as
a
guide for when to
petform scheduled maintenance.
REMOTE PANEL
For remote operation of the generator system, the same three
switches are used. The PREHEAT and START switches
are
connected in parallel with the gauge panel's switches and
serve the same functions as in the gauge panel. The STOP
switch is in series with the gauge panel's STOP switch and
serves the same function. There is a REMOTE START/STOP
WIRING DIAGRAM in this manual.
