19.7 Elektronic reversing starter
Optionally, the motor of the actuator is controlled by an electronic reversing contactor (thyristors). The elec-
tronic reversing contactor switches two of the three motor phases. The control of the two directions of rotation
is locked by hardware in the electronic reversing contactor. Compared to conventional mechanical contactors
there is no mechanical wear through contact burning; in case of electronic reversing starters this feature in-
creases the life and reliability of modulating actuators with high switching frequency.
Attention: The third phase is not switched in the electronic reversing contactor and is therefore
constantly on the motor winding.

19.8 Power supply
The internal supply of the SMARTCON control unit is made via the power connection. At 3-phase current a
neutral phase is not required. The following table shows the possible different voltage ranges of the control.

For the supply voltage of the complete system (control unit and actuator) also the motor voltage
must still be considered (see actuator data and name plate)!
