4 MAINTENANCE
4.1
GENERATOR
Keep the generator clean and in dry condition. Check if
cooling air has free access. Check the V-belt for alignment
and for wear out (refer to figure 7).
Replace when the V-belt
shows signs of wear out. The lifetime of the brushes and
bearings is strongly depending on the installation,
environmental conditions and application. In good
conditions and mild application the average life time of the
bearings is at least 6000 hours for the front bearing and
20.000 hrs for the rear bearing.
Every 1000 hours the bearings must be checked. The
average life time of the brushes is 7500 hrs. Every 1000 hrs
the brushes must be checked.
A belt too tight or too loose will reduce the life
of the belt and generator (pulley and bearings)
and will reduce the performance.
4.2
INVERTER BOX
The electronic equipment itself in the inverter box does not
require any maintenance. Keep the air inlet opening free
from dirt and blockages. The air filters inside the box are
designed for fife time use. In case of extreme polluting
conditions the filters must be changed by an authorized
service station. The inverter box cannot be opened without
special tools. The cover must not be removed at any time.
Service on the electronics must only be made by authorized
personnel.

5 TROUBLE SHOOTING
5.1
GENERATOR/ELECTRICAL FAULTS
Beware of parts which are live! The generator
generates a high voltage up to 340 Volt
5.1.1
General
If any problem should occur, check basic conditions and
examine all external wiring, switch gear and circuit
breakers. Check if the V-belt slips. Check the V-belt
alignment (refer to figure 6). Also check if measuring
instruments give the correct value. If in doubt, measure
directly on the inverter and generator terminals with an
independent instrument. A failure code is displayed when a
failure in the system is detected. Refer to the following
pages.
