Note (Wiring diagram)
(H2) = Feedback circuit | The control recognises cross-short, cable break and earth leakages 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. | 2 channel control shown for a guard-door monitor with two contacts, of which at least one contact has positive break, with external reset button (R). | The wiring diagram is shown with guard doors closed and in de-energised condition.
