Notes
Note (General) | Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit. |
Circuit example
Note (Wiring diagram) | If only one inductive proximity switch is connected to the standstill monitor, the standstill frequencies must be identical and inputs X1 and X2 must be bridged. |
