Generator Faults

11.3.11
If the above test produces no result, it can be assumed that the actuator operates smoothly. The electrical groups of
components must then be checked:
1. Re-connect plug.
2. Start generator.
3. Turn the actuator by hand to check whether the Spindle is reversed by the motor.
4. It can be assumed that the actuator is faultless, if the turning of the actuator is too much for the hand (It is not nor-
mally possible to stop the motor with the fingers). It must be assumed that there is a fault with the voltage control
(VCS).
7.7.6.1 The following measures are necessary if the actuator is jammed:
1. If the actuator only turns weakly:
• Actuator has a destroyed winding and must be exchanged. (In future it should be ensured that the generator is not
overloaded).
2. If the actuator does not move, but the spindle can be turned by hand:
• Remove plug from the actuator and temporarily connect it to an external 12 volt direct current source. The motor is
defective if the actuator still does not turn when connected to the external electrical source. Exchange the motor.
Actuator operates with external voltage source and works without flaws
1. Check VCS board fuse.
2. Check if measuring voltage is applied to the VCS board.
3. Check if supply voltage is applied to the VCS.
4. Check if the activation signal of the actuator is applied to the VCS’ output.
The VCS circuit board should be exchanged if these measures do not produce clarity.
7.7.6.2 Checking the generator voltage limitation
The mechanical voltage limitation must be checked regularly.
1. Switch the load off
2. Disconnect the plug of the actuator.
3. Connect an electrical voltmeter.
4. Start the generator.
5. Turn the actuator to the lowest limit point by hand. The min voltage is 220 V (110 V).
6. The voltage must be 225 V (110 V).
7. Turn the actuator to the upper limit by hand. The max. voltage is 260 V (130 V).A new adjustment is necessary in
case of deviants.
