5.2 Engine faults
CAUTION!
Remove 3 Amp. fuse in the control panel while working
on the generator 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 table to find the cause of a wrong
engine speed. When there is no obvious cause one can adjust the
RPM (see 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.
CAUTION!
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.
A failure code is displayed when a hardware failure at the
generator is detected.
