A.4.5 Starting the Generator by a „Failure bypass switch“
There is a "pressure switch" on the operation side above the power relays. Faults (e.g. caused by
overheating) can be manually overcome by means of this switch. The generator can be started by
using the remote control panel. The operating temperature can be reduced for a short period of
time (without stress of course), so that the fault switch returns to the original position should over-
heating cause the generator to shut down because of overheating.
ATTENTION: - Before using the failure bypass switch, it is important to check the oil
level, since the oil gauge is deactivated by the switch. For a further reason it is important
to switch off the generator electrical load before the generator is shut down:
Before stopping the generator it is highly recommended that electrical devices (e.g. refrigerating
compressors, air conditioning compressors etc) are switched off, because the voltage drops as
the rotational speed (rpm) decreases as the engine comes to a halt.
(Also see information regarding voltage control with automatic shut-off for protection of load when
over or undervoltage occurs).
This is also the case when the generator is started when load is switched on.
Normally the generator will no longer excitate if a certain amount of base load is stepped up. The
electrical load should also be shut-off before starting the generator.
If started under electrical load, the engine will still run but the generator will not generate the pro-
per voltage (or even no voltage) since the stator windings do not have the chance to reach full
excitation. Electrical units which are switched on in this condition could possibly be damaged
(special caution should be practised with electric motors to avoid burnout).
