Figure 102
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.
For AKD5, considering 3000A as a rated current (In), fans will activate when the current
crosses 2500 amps & will stop if the current drops below 2300 amps.
