Generator Operating Instructions
Panda 14.000 NE PVK-U S00420 - Chapter B: Generator Operating Instructions Page 29
The AC voltage should be within a tolerance of ± 3 Volt without load at the nominal voltage. When running without
load, the generator frequency should be 4% below the nominal voltage. The generator should be checked, before
the load is switched on, if the current remain at this level.
8. Switch on load.
The load should only be switched on if the generator voltage is within the permissible range. Parallel connection of
several load should be avoided, especially if there is load with electric motors, such as air-conditioning units in the
system. In this case, the load must be connected Step by Step.
B.2.5Stopping the Generator
1. Switch off load.
2. If the load is higher than 70% of the nominal load, then generator temperature should be sta-
bilised by switching off the load for at least 5 minutes.
At higher ambient temperatures (more than 25°C) the generator should always run for at least 5 minutes without
load, before it is switched off, regardless of the load.
3. Press generator "OFF" button and switch off (Position 12 on Control panel).
4. If necessary, press additional switch (battery switch, fuel stop valve).
B.2.6Starting the Generator when overheated by a "Failure Bypass Switch“
There is a "pressure switch" on the operation unit. 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 overheating 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).
