Wiring example
| Note (Wiring diagram) |
The control system recognises wire-breakage and earth faults in the monitoring circuit. The example shows a 1-channel control with contact A for a guard door monitor; of which at least one contact has positive break; with external reset button (R). Relay outputs: Suitable for 1 channel control, for increase in capacity or number of contacts by means of contactors or relays with positive-guided contacts. The wiring diagram is shown with non-actuated limit switches and in de-energised condition. (H2) = Feedback circuit |
