3.1 General
The PSG1 is a frequency converter for the operation of oscillating conveyors with Pi-
ezo drive. It generates an adjustable drive frequency which is independent of the
mains frequency. The output voltage is adapted to the Piezo unit so that voltages be-
tween -30 and 150 V are generated.
In addition, the device provides a constant conveying capacity for mains voltage fluc-
tuations through an internal offset. The device is controlled via an enable input in
such a way that the upstream capacitors are neither charged nor discharged
(Start/Stop).
Repair work must be carried out by qualified personnel only. We
recommend that repairs are carried out on our premises.
During switch-on, internal capacitors cause a high inrush current.
Especially if several controllers are switched on simultaneously,
the external fuse can blow or the circuit breaker can trip.
