5.3.3 Contactor Monitoring
The contactor monitoring function ascertains whether or not externally connected contactors are switched
within the specified period of time. The contactor monitoring input is monitored for a low flank to this end.
Switching time may not exceed
200 ms. This function only provides for additional safety if positively driven
external contactors are utilized.
24 V are returned to the contactor monitoring input via an available NC contact at the external contactor.
If the Contactor Monitoring function is combined with the operation mode Fix Blanking, Floating Blanking, Auto
Floating Blanking or Reduced Resolution, first configure the respective operation mode, then activate the function.
