Current thresholds Function
91 | © 2023 ABB | 1SDH001330R1002 - ECN000297030
The Current thresholds allow checks to be set along the current lines, to be associated with the
programmable contacts of the Ekip Signalling modules (in all versions).
Two pairs of programmable contacts are available:
• Threshold 1 I1 and Threshold 2 I1, with control referring to I1
• Threshold Iw1 and Threshold Iw2, with control relating to In
The thresholds can be enabled and set in the Advanced - Signaling menu (page 47).
IMPORTANT:
• the current thresholds do not manage the trip, but only the signal
• the function is activated if the trip unit is powered by auxiliary voltage
Parameters
Threshold Available parameters
Enable : Activates the protection and availability of the threshold
in the menu
Threshold 1 I1
Threshold : The value is given in percentage of threshold I1 and
can be set within the range: 50% I1 to 100% I1, in 1% steps.
Enable : Activates the protection and availability of the threshold
in the menu
Threshold 2 I1
Threshold : The value is given in percentage of threshold I1 and
can be set within the range: 50% I1 to 100% I1, in 1% steps.
Enable : Activates the protection and availability of the threshold
in the menu
Direction : allows the user to choose whether to have the signal
when the current is higher (Up) or lower (Down) than the
Threshold Iw1
threshold.
Threshold : The value is given as both absolute value (amperes)
and relative value (In) and can be set within the range: 0.1 In to 10
In, in 0.01 In steps
Enable : Activates the protection and availability of the threshold
in the menu
Direction : allows the user to choose whether to have the signal

Threshold Iw2
threshold.
Threshold : The value is given as both absolute value (amperes)
and relative value (In) and can be set within the range: 0.1 In to 10
