7.6.2 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)

… as logic input for

monitoring functions

… as source for digital outputs

… 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

… 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
