5 TROUBLE SHOOTING

5.1 ALTERNATOR/ ELECTRICAL FAULTS

Beware of parts which are live!

Before working on the generator, remove the

30Amp fuse from the local control panel (see

figure 3) to prevent the engine from starting

5.1.1 General

If any problem should occurs, check basic conditions and

examine all external wiring, switch gear and circuit

breakers. Also check if measuring instruments give the

correct value. If in doubt, measure directly on the

alternator terminals with an independent instrument. This

should only be carried out by an experienced electrician.

Check if the engine is running correctly at 3000 (50 Hz)

RPM according to its settings and does as well under load.

A RPM drop of 5% at full load is acceptable. Therefore a

no load setting should be at 3150 RPM = 52.5 Hz. Under

no circumstances should the RPM under full load be below

2940 RPM = 49 Hz

When the problem is in the RPM refer to section 5.2.

When the generator was stopped due to an electrical

failure, the origin of the failure that stopped the generator

will be displayed on the MasterView Easy remote control

panel. See section 5.1.2.
