Considering 4000A as a rated current (In) , fans will activate when the current crosses 3600
amps & will stop if the current drops below 3400 amps.

Figure 48

The current thresholds allow you to set controls on current lines, to be combined with the
programmable contacts of the Ekip Signalling modules.

Two pairs of programmable contacts are available:

Threshold 1 I1 and Threshold 2 I1, with control referred to I1
Threshold Iw1 and Threshold Iw2, with control referred to In

For Fan control configure Iw1 and Iw2.
