- notice | The PFH value is applicable for the combinations listed in the table for contact load (K) (current through enabling paths) and switching cycle number (n-op/y). In case of 365 operating days per year and a 24-hour operation, this results in the specified switching cycle times (t-cycle) for the relay contacts. Diverging applications on request.

notice - Wiring example |
|
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). |
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. |
(H2) = Feedback circuit |
The control recognises cross-short, cable break and earth leakages in the monitoring circuit. |
The wiring diagram is shown with guard doors closed and in de-energised condition. |
