| Note (General) |
Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit. |
Wiring example
| Note (Wiring diagram) |
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. The example shows a 2-channel control of 2 muting sensors and an external master reset button. The wiring diagram is shown with non-actuated muting sensors and in de-energised condition. (H2) = Feedback circuit F1 = Electronic fuse |
