Function
The Current Thresholds allow controls to be set on the current lines, to be connected to the programmable
contacts of the Ekip Signalling modules (in all versions). Two pairs of contacts are available:
• Threshold 1 I1 and Threshold 2 I1, with control referring to I1.
• Threshold Iw1 and Threshold Iw2, with control referring to In.
IMPORTANT:
• The current thresholds do not manage the trip, but only the signal.
• The function is active if the trip unit is energized by an auxiliary power supply or Ekip
Measuring Pro.
Parameters
Here is a list of the available parameters:
Parameter Description
It is possible to do the following:
Threshold 1 I1 • Enable the function.
• Set the activation percentage value
It is possible to do the following:
Threshold 2 I1 • Enable the function.
• Set the activation percentage value
It is possible to do the following:
• Enable the function.
Threshold Iw1 • Set the threshold.
• Set activation to obtain the signal when current is higher (up) or lower (down) than
the threshold value. See the following graph.
It is possible to do the following:
• Enable the function.
Threshold Iw2 • Set the threshold.
• Set activation to obtain the signal when current is higher (up) or lower (down) than
the threshold value. See the following graph.
NOTE: the thresholds Iw1 and Iw2 are expressed both as an absolute value (Ampere) and a
relative value (In, nominal value defined by Rating Plug).
