Generator Failure
Page 48 Panda 14.000 NE PVK-U S00420 - Chapter D: Generator Failure
The generator can’t be damaged by an overload because the winding is overload- and short-cir-
cuit safety. But damages are possible in the periphery. Especially connected load is endangered
because a lower voltage can damage them by order.
Possible disturbances in the area of the rev regulation "VCS"
Failure Cause
The spindle of the actuator jams • not regularly lubricated.
• surface is mechanical damaged.
• actuator is defect.
• defect of the VCS control (short of winding).
• signal 230V (115V) AC missing.
• limiting nut jams the spindle.
Fuse on the printed circuit board of the
VCS control is melted. • constant overload of the generator.
Steps to check the voltage control by a disturbance:
1. Switch off all electrical load.
2. Disconnect the plug of the actuator.
3. Turn the actuator manually to check if the adjusting nut is jamed to the limit stop points.
4. Turn the actuator manually to check if the adjusting nut on the spindel runs faultless.
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.
