Parameter Dir. Interm. EF allows you to define the type of fault handling and fault logging. If set to ON,
tripping is possible and a fault log is generated. If set to ON with GF log, tripping is possible, a fault log and
a ground fault log are generated. If set to Alarm Only, no tripping is possible. Only an alarm is generated.
Furthermore, only a ground fault log is created.
The raising pickup of the function (indication 6972 „dIEF pick up“) is the criterion for opening the ground
fault log.
