Generator Failure

If there is no result by these steps the actuator is working mechanically correct. After this the electrical components
must be checked:
1. Connect the plug of the actuator.
2. Start the generator.
3. Turn the actuator by hand and check if the spindle turns back by the motor.
4. If the motor react on the turn by manual strongly (the motor can normally hold with the fingers) the drive will be
working faultless. If there are nevertheless faults in the voltage control there is a fault in the control VCS.
8.5.4.3 If the actuator is not moving the following points are necessary:
1. The motor turns not strongly rather 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.
The actuator don’t turns with the external voltage source. The actuator is defect and have to be changed.
The control must be inspected by the following steps if the actuator turns und works faultless with the external
voltage source:
1. Check the fuse on the VCS printed circuit board.
2. Check if the sense voltage is wired to the VCS printed 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.
8.5.4.4 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 220V.
7. Turn the actuator manually to the upper limit stop point. The max. voltage is 270V.
8. A new adjustment is necessary in case of deviants.
8.6 Low Generator-Output Voltage
If the produced alternating voltage is too low, switch the consumers off, in order to relieve the generator. Mostly the
problem already solved. If the output voltage is still too low, even if all consumers are switched off, the generator
runs without load, you can assume one or more condensers are defective.
