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
