Check engine Speed/Adjust Fuel Pump
Every 400 operating hours
Checking the Engine Speed
The frequency of the mains voltage is not the same all over the
world.
This frequency can either be 50 or 60 Hz. for example, the fre-
quency in Europe is usually 50 Hz, while in the United States it
is 60 Hz.
The frequency of the generator set will be the same as the mains
frequency in your cruising area.
N.B.: If you want to connect your on-board network to a
dockside connection outside your usual cruising area, take care
to check that both voltage and frequency are the same as that
for your generator set.
The speed of the generator will decrease as the load increases.
So adjust the generator as follows:
All GHS generator sets:
The RPM for a generator without load is about 3100 rpm
(5.5-Hz).
All GLS generator sets:
The speed for a generator without load is about 1550 rpm
(5.5-Hz) or about 850 rpm (6.5 Hz).
Allow the engine to run until it is warm (coolant temperature
about 60 degrees C (40 deg. f) or higher) before checking the
speed and adjusting, if necessary.
Check the speed using a rev. counter, or use a frequency meter
connected to the
electrical installation.
The correct speed can be set using the adjusting screws on the
fuel pump.
