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 consumers are
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 (short of winding).
• defect of the VCS control.
• signal DC 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 consumers.
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. The spin-
dle has a clockwise rotating thread, use a wrench SW14 to the assistance take.
If there is no result by these steps the actuator is working mechanically correct. After this the elec-
trical 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 reacts strongly to the manual turn (the motor can’t normally hold with the fingers)
the drive will be working correctly. If the voltage control works faulty anyway there is a fault in
the control VCS.
