Generator Failure

If the actuator is not moving the following points are necessary:
1. The motor turns only weak:
• The actuator has shorts in the winding and must be changed. (pay attention that the generator
is not overloaded anymore.)
2. The actuator does not move but the spindle can be turned manually:
• Disconnect the plug of the actuator. Connect provisional an external voltage source 12V-DC to
the motor. If the actuator with the external voltage supply does not turn likewise, the actuator is
defective. Exchange actuator.
The actuator don’t turns The actuator is defect and have to be changed.
The actuator turns and works
faultless: 1. Check the fuse on the VCS printed circuit board.
2. Check if the sense voltage is wired to the VCS circuit board.
3. Check if the VCS supply voltage is wired to the VCS.
4. Check if the VCS outlet signal for the actuator is wired.
Change the VCS printed circiut board if the points above carries no clearance.
Check the limitation of the generator voltage
The mechanical voltage limitation must be checked regularly. The following steps have to be
done:
1. Disconnect the plug of the actuator.
2. Switch off all consumers.
3. Connect an electrical voltmeter.
4. Start the generator.
5. Turn the actuator manually to the lower limit stop point.
6. The voltage must be 23V.
7. Turn the actuator manually to the upper limit stop point. The max. voltage is 96V.
8. A new adjustment is necessary in case of deviants.
D.1.7 Low Generator Output Voltage
ATTENTION! Before working on the system read the see “Safety Precautions” on page 10.
Panda generators are designed such that even high electrical disruptions will not cause serious
damage to the generator.
If the generator does not produce any voltage while the diesel drive engine is running, the
suspected cause lies outside the generator capsule.
• electrical load not switched off prior to start
• short circuit somewhere in electrical system
• electrical overload
