Shutdown threshold values for resistance (R
 
Low shutdown threshold values: may lead to false tripping.
High shutdown threshold values: the device may not trip at all.
4. System settings of the relays (menu 6.6)
The factory setting for the relays is N/C operation. In case of a self test, the relays switch.
N/C operation: Relay is energised during normal operation and is deactivated in the
event of a fault ("fail-safe")
N/O operation: Relay is de-energised in normal operation and is activated in the event of
a fault ("not fail-safe")
5. Field calibration (menu 6.7)
After the parameters have been entered, a field calibration can be carried out to set R
