7.6  Monitoring fault-currents 

Each (optional) fault current module provides 

two channels

 for monitoring residual or fault current. For 

each of the channels an alarm and a prewarning limit can be defined, which can be used as follows: 

…  Activating a 

summary alarm

 when the alarm limit is violated or a breakage occurs (2mA input only) 

…  Entry into the alarm list, if the state of the alarm limits monitoring changes or when a breakage 

occurs (2mA input only) 

…  Entry into the event list, if the state of the prewarning limits monitoring changes 

And via PLC application: 

…  as source for digital outputs  

…  the value of the individual fault currents can also be output via the analog outputs 

 

The present values of the monitored fault currents are visible via the menu of the instantaneous values: 

 

Meaning of the used symbols 

 

Current value normal 

 

Prewarning limit violated 

 

Alarm limit violated 

 

Alarm: Configured limit for ON 

 

Alarm: Configured limit for OFF 

 

Prewarning: Configured limit for ON 

 

Prewarning: Configured limit for OFF
