notice
Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.
notice - Wiring example
Input level: The example shows a 2-channel control of a guard door monitoring with two position switches, whereof one with positive break, external reset button (R); cross-wire monitoring and feedback circuit (H2)
If more guard doors are monitored, they must be connected according to the wiring table
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.
A single failure in the sensors does not cause the safety to be lost
If the single failure occurs, the safety function will be maintained. Some, although not all, errors will be recognised. An accumulation of unrecognised errors could cause the safety function to be lost.
Automatic start: The automatic start is programmed by connecting the feedback circuit to the terminals X1/X3. If the feedback circuit is not required, establish a bridge
The wiring diagram is shown with guard doors closed and in de-energised condition.
