Generator Failure
Change this fuse (1,6A slow to blow)
Fig. 7.4.4-1: VCS
The generator can’t be damaged by an overload because the winding is overload- and short-circuit safety. But
damages are possible in the periphery. Especially connected consumers are endangered because a lower voltage
can damage them by order
The Mini VCS has no fuse to change

is melted.
7.4.4.2 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 jammed to the limit stop points.
4. Turn the actuator manually to check if the adjusting nut on the spindle 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.
7.4.4.3 If the actuator is not moving the following points are necessary:
