Wiring example
- Note (Wiring diagram)
- The wiring diagram is shown with guard doors closed and in de-energised condition. | 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. | The control recognises cross-short, cable break and earth leakages in the monitoring circuit. | Input level: the example shows a 2-channel control of an Emergency Stop command device (level 1) with external reset button (R), and guard door monitoring (level 2) with feedback circuit (H2). | Automatic start (level 1): The automatic start is programmed by connecting the feedback circuit to the terminals X1/+24 V DC. Automatic start (level 2): The automatic start is programmed by connecting the feedback circuit to the terminals X2/+24 V DC. If the feedback circuit is not required, establish a bridge. | 1 NC contact each time communicates the status of level 1 and level 2
