Startingjstopping Procedure - Westerbeke 5.0Kw BCDR Operator's Manual

STARTING/STOPPING PROCEDURE
THE STARTING SYSTEM
Westerbeke diesel generators use electric starters assisted by
glow plugs for both nonnal and cold weather starting. The
illustration below shows a cross-sectional view of one
cylinder. The glow plug is located in the pre-combustion
chamber so that its tip is in the injector nozzle's spray path.
When the glow plug is energized by the PREHEAT button,
the plug glows red at the tip and assists in igniting the fuel.
The result is a rapid start with less wear on the starter.
This system is common to WESTERBEKE diesels. The start
circuitry is designed so that the PREHEAT button must be
depressed for the time specified in the preheat chart. Then,
while keeping the PREHEAT button engaged, the START
button is depressed to crank the engine.
NOTE:
The START switch will not energize unless the
PREHEAT switch is depressed. Depressing the PREHEAT
switch activates the glow plugs in the cylinder head so use
the PREHEAT intermittently to avoid overheating the glow
plugs.

PREHEAT: Depress the PREHEAT switch. The voltmeter and
panel lights, gauges and meters will be activated. The PRE-
HEAT switch should be depressed in accordance with the
following chart:

limit of continuous usa 30 seconds before cranking
START: While still depressing the PREHEAT switch, depress
the START switch. This will engage the starter solenoid.
Upon engine starting, release the START switch. Do not
release the PREHEAT switch until the oil pressure reaches
15 psi. Then as long as the high water temperature and low
oil pressure protective circuits do not activate, the engine will
remain energized and continue to run.

NOTE:
When starting:
. A voltage drop will occur
when the preheat switch
is depressed.
Should the engine not start when the START switch is
depressed for 10 to 20 seconds, release both switches and
wait 30 seconds; repeat the procedure above and preheat
longer. Never run the starter for more than 30 seconds.
Remote Starting Procedure
The remote start panel is the same as the engine-mounted
start panel except that it has a green LED light and no
gauges. When starting at a remote location, the green LED
lights when the generator is running at approximately 600
rpm. This indicates when the START switch can be released
since the starting of the generator may not be audible.
A. When the PREHEAT switch is depressed at the remote
start/stop panel the LED light will illuminate. When the
START switch is depressed and the starter cranks the
engine this LED light will
dim.
When the engine starts
the LED light will brighten signaling to release the
START switch. Continue to hold the PREHEAT depressed
for a few seconds to allow oil pressure to build up which
closes the oil pressure safety switch that is in the series
path for 12V B+ to the K2 run relay/fuel run solenoid.
The green LED will remain brightly illuminated while the
engine is running.
B. After the generator is started and the START switch is
released, the generator's starter will not crank unless the
PREHEAT switch is operated first because this switch
supplies voltage to the START switch.
Once the engine starts, check the engine's instruments for
proper oil pressure and battery charging voltage. Apply a
light load to the generator and allow the engine's operating
temperature to come up to 140-150
0
(60-66
0
C) before
applying heavy loads.
NOTE:
Some unstable running
may
occur in a cold engine.
Depressing the PREHEAT switchfor 10-15 second intervals
will help stabilize the engine RPM until the operating
temperature reaches the 140 - 150
0
F and a load is applied
to the engine.
