Disconnected injection (Disconnect. Inj.)
The device detects a high insulation resistance in the system and can detect the following disconnections:
Between the device and IM400-1700 voltage adaptor
Between the device and PHT1000 voltage adaptor
The allowed values for this parameter are OFF and ON. The default value is OFF.
On small networks without loads and transformer, where the insulation level is high, or during commissioning without loads and transformer, it is advised to set the parameter to OFF.
Detection of disconnection between the device and IM400-1700 or PHT1000 voltage adaptors is always active and does not depend on the value of the parameter.
If the injection disconnects, the device displays DISCONNECTED INJECTION DETECTED and product status LED turns ON. See Special status screens for device display.
