Application and Setting Notes
Parameter: Level of warning 1
•
Default setting (_:101) Level of warning 1 = 5 %
With the parameter Level of warning 1, you define the percentage the measured value is allowed to
exceed the parameter CB make time at the output Make time , before the output Warning 1 is set. The
output Warning 1 then drops out after 100 ms.
Parameter: Level of warning 2
•
Default setting (_:102) Level of warning 2 = 10 %
With the parameter Level of warning 2, you define the percentage the measured value is allowed to
exceed the parameter CB make time at the output
Make time , before the output Warning 2 is set. The
output Warning 2 then drops out after 100 ms.
Parameter: Oper.current threshold
•
Default setting (_:103) Oper.current threshold = 0.100 A
With the parameter Oper.current threshold, you define the current threshold. If the measured value
exceeds this threshold, the measured value is detected as flowing operating current. As soon as an operating
current flows, the end of the time interval Make time is detected.
Parameter: Delay correction time
•
Default setting (_:104) Delay correction time = 0.000 s
With the parameter Delay correction time, you define a correction value which will be subtracted from
the Make time during calculation. This allows you to compensate delays caused by the system, for example,
relay residual times, if necessary.
