Relay outputs: Suitable for 2 channel control, for increase in capacity or number of contacts by means of contactors or relays with positive-guided contacts. In case of a 1-channel control, connect the NC contact to the operating voltage and bridge S11/S12 and S21/S22. Automatic start: The automatic start is programmed by connecting the feedback circuit to the terminals X1/X2. If the feedback circuit is not required, establish a bridge The wiring diagram is shown with guard doors closed and in de-energised condition.
