Seg WI Series Reference Manual

Meth.Detect.Bkr.Pos. Description
Current-Based The breaker position is determined based on current measurement.
Aux-Based The breaker position is dependent on a particular input signal (Aux contacts 52a/52b of
the circuit breaker).
Current and Aux The breaker position is determined based on current measurement AND input signal
(Aux contacts 52a/52b of the circuit breaker).

Reset Mode
Selection list referenced by the following parameters:
• ╚═▷ I> . Reset Mode•
Reset Mode Description
instantaneous Instantaneous reset: when the current drops below the pickup setting, the TOC time
resets to zero within 2 cycles.
de󰈛nite time Reset after a 󰅰xed time.
(Remark: This delay is then de󰅰ned by the parameter »t-reset delay«.)
