Safety Shutdown Switches - Westerbeke 5.0Kw BCDR Operator's Manual

STARTING/STOPPING PROCEDURE
STARTING UNDER COLD CONDITIONS
. Make sure !he lubricating oil conforms with the ratings for
the prevailing temperature. Check the table in the ENGINE
OIL section in this manual.
The battery should be fully charged to minimize voltage
drop .
.use a sufficient amount of
prehea~
to aid in starting. See the
Temperature!Preheat chart elsewhere in this section.
STOPPING PROCEDURE
1. Remove the AC electrical load from the generator and
allow the generator to run for three to five minutes to
stabilize its operating temperatures.
2. Depress the STOP switch and hold it until the generator
is completely stopped.
3. Now release the STOP switch .
. SAFETY SHUTDOWN SWITCHES
The engine is protected by
three
automatic shutdown
switches. Should shutdown occur,
do
not attempt to restart
without finding
and
correcting the cause. Refer to the
heading "Engine Stops" in the TROUBLESHOOTING
section of this manual.
. The following is a description of these automatic shutdown
switches:
Coolant Temperature Switch
A high water temperature switch is' located on the thermostat
housing. Nonnally closed, this switch, should the fresh water
coolant's operating temperature reach approximately 210
0
P
(99°C), will open and interrupt the DC voltage to the K2'
relay, thereby shutting off the engine. Tins switch resets at
195°P (107°C).
THERMOSTAT
ASSEMBLY
Remote Stopping Procedure
To stop the generator, depress the STOP switch which opens
the normally closed B+ path for voltage to the engine's run
circuit. The STOP switch must be held open until the
generator comes to
a
complete stop and the green LED light
goes out.
Low Oil Pressure Switch
A low oil pressure shutdown switch is located off the
engine's oil gallery. Normally open in a static state, this
switch's sensor monitors the engine's oil pressure. Should the
engine's oil pressure fall to 5-10 psi, this switch will open,
interrupting the DC voltage to the K2 relay, thereby shutting
off the engine. .

WIRED FOR OPTIONAL
. AUDIBLE ALARM
The generator's engine is protected by an engine mounted
manual reset circuit breaker (20 amps DC). Excessive current
draw or electrical overload anywhere in the instrument panel
wiring or engine wiring will cause the breaker to trip. In this
event the generator will shut down and the voltage to the K2
relay is terminated. If this should occur, check and repair the
source of the problem. After repairing the fault, reset the
breaker and restart the generator.
