5.2 ENGINE
FAULTS
Before working on the generator, remove the
30Amp fuse from the local control panel (see
figure 3) to prevent the engine from starting
5.2.1 General
Most electrical problems relating to Voltage or Frequency
are due to wrong engine speed. Note that RPM and Hz
are basically the same.
Use the problem solving tables to find the cause. When
there is no obvious cause one can adjust the RPM (refer
to special procedures).
When the engine is not cranking well starting problems
almost always originate from battery problems or poor
battery cable connections. When the engine is cranking,
well starting problems almost always originate from lack of
fuel or air bubbles in the fuel pipes.
When the engine does not start instantly,
prolonged cranking can fill up the exhaust
system with cooling water because of the
water injected exhaust. When the water
enters the cylinder through the valves this will
bring severe damage to the engine. When the
engine does not start and repeated cranking
is necessary shut off the seawater inlet. Open
the valve immediately after the engine has
started.
When the generator was stopped due to a engine failure,
the origin of the failure that stopped the generator will be
displayed on the MasterView Easy remote control panel.

--
Service needed
Time to service interval has elapsed.
Generator needs maintenance, see chapter 4
of this manual
Oil pressure low
Oil pressure too low (oil pressure switch tripped)
See section 5.2.3
Engine temp high
Engine temperature too high (engine
temperature switch tripped)
See section 5.2.3
Exhaust temp hi
Exhaust temperature is too high (exhaust
temperature switch tripped)
See section 5.2.3
Water pressure
Water pressure too low, water pressure switch
tripped
See section 5.2.3
Communication
Communication error between the generator set
and the apparatus that gave a command which
resulted in starting of the generator set. For
instance connection between the generator set
and the MasterView Easy was lost.
Check MasterBus wiring between generating
set and remote panel. See user’s manual of
the remote control panel
Start failure
Engine fails to start.
See section 5.2.3
Not configured
No serial number was assigned to the generator
set. This may mean that calibration of the
generator fails.
Contact your supplier.
