| notice - Wiring example |
| |
| Input level: The example shows a 2-channel control of a guard door monitoring with two position switches, whereof one with positive break, external reset button (R) and feedback circuit (H2). |
| The control recognises cable break in the monitoring circuit. |
| 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. |
| For 1-channel control, connect NC contact to S11/S12 and bridge S12/S22 |
| Automatic start: The automatic start is programmed by connecting the feedback circuit to the terminals S12/X3. If the feedback circuit is not required, establish a bridge |
| The wiring diagram is shown with guard doors closed and in de-energised condition. |
