Safety Shutdown Switches - Westerbeke 8.0 KW-60Hz SBEG Operator's Manual

SAFETY SHUTDOWN SWITCHES
DESCRIPTION
The engine/generator is protected by switches and sensors
that send signals to the ECU that it interprets as a fault and
automatically shuts down the generator drive engine. When
an automatic shutdown occurs, one of the control panel fault
LED lights will illuminate indicating what fault caused the
engme to shutdown. TIlls LED will stay illuminated. To
correct the fault, refer to ENGINE TROUBLESHOOTING in
this manual. Do not attempt
to restart the generator
before correctiog the fault.

CONTROL PANEL INDICATOR LIGHTS
PRESSURE
FUSE
Four LED fault ligbts are located on the generator control
panel and the remote start/stop panels. Should a problem
occur during generator operation the individual light will
indicate Where the problem is and at the same time shut the
generator down. The light wjll continue to glow after the
generator shuts down. Should this occur, refer to ENGINE
TROUBLESHOOTING in this manual.
OIL GALLERY
OIL PRESSURE SENSOR
An oil pressure sensor (located just below the oil filter) sends
a DC Voltage to the ECU that it interprets as oil pressure.
Should this voltage faIl below a certain level, the ECU will
shut the generator down and illuminate the low oil pressure
LED. Should this occur, refer to ENGINE
TROUBLESHOOTING in this manual.
EXHAUST TEMPERATURE SWITCH
A temperature switch is mounted on the exhaust elbow to
monitor the temperature of the exhaust coolant and gasses.
Should the switch sense an excessive exhaust temperature, the
ECU will shut the generator down and the exhaust
temperature LED will illuminate on the control panel. Should
this occur, refer to ENGINE TROUBLESHOOTING in this
manual.
COOLANT SENSOR
THERMOSTAT
ASSEMBLY
COOLANT TEMPERATURE SENSOR
A coolant temperature sensor is located on the thennostat
housing to monitor the engines fresh water coolant. Should
the coolant temperature reach 21O"F, the ECU will shut the
generator down and the engine temperature LED will
illuminate. Should this occur, refer to ENGINE
TROUBLESHOOTING in this manual.
OVERSPEED SWITCH
An overspeed high RPM shutdown sensor in the ECU will
shut the engine down if the engine RPM"S exceed the set
limit and the LED will remain lit. If an underspeed problem
occurs, the engine will shutdown and the LED will remain
flashing.
DC CIRCUIT BREAKER
The generators engine is protected by a panel mounted man-
ual reset circuit breaker (20 amp). An electrical overload in
the engine's wiring hamess or the instrument panel will trip
this breaker and shutdown the engine/generator. If this should
occur, inspect and repair the problem. then reset the breaker
and sestart the engine/generator.
