| notice | |
| Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit. | |
| 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 system recognises wire-breakage and earth faults 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. | |
| 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. | |
