Wiring example
| Note (Wiring diagram) |
The wiring diagram is shown with guard doors closed and in de-energised condition. 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. 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). Control category 3 to EN ISO 13849-1 for 2-channel loop in the supply voltage UB. (H2) = Feedback circuit |
