REX610 Technical Manual

Exclusion mode is on when the value of the Exclusion time parameter is higher than zero. During the exclusion mode, new triggerings are ignored if the triggering reason is the same as in the previous recording. The Exclusion time parameter controls how long the exclusion of triggerings of same type is active after a triggering. The exclusion mode applies only to the analog and binary channel triggerings, not to periodic and manual triggerings.

When the value set with the Exclusion time parameter is zero, the exclusion mode is disabled and there are no restrictions on the triggering types of the successive recordings.

The exclusion time setting is global for all inputs, but there is an individual counter for each analog and binary channel of the disturbance recorder, counting the remaining exclusion time. The remaining exclusion time can be monitored with the Exclusion time rem parameter (only visible via communication, IEC 61850 data ExclTmRmn) of the corresponding analog or binary channel. The Exclusion time rem parameter counts downwards.
