4. CONNECTION OF THE LINE CURRENT TRANSFORMER
Mount the current transformer on the phase non concerned with the pick-up of the voltage signal by the reactive power regulator (usually phase L1
also marked by R) and before the branch supplying the power factor correction board (the transformer should measure the current of the loads plus
that of the power factor correction board).
The current transformer should be of class 0,5 or 1 with apparent power at least 6VA. If other loads are present in parallel to the current transformer,
check their power consumption; increase the apparent power if necessary. When the distance of the current transformer from the unit is less than or
2
equal to 20m use 4mm cables for connection; if not, increase the size of the cables (for further information, consult the ICAR Technical Service
department).

MEANING
All the available steps are connected but the cosφ is still more inductive than the
setpoint.
The current flowing in the current inputs is lower than minimum measuring range.
This condition can occour normally if the plant has no load.
The current flowing in the current inputs is lower than minimum measuring range.
The measured voltage is lower than the threshold set with P17.14.
The measured voltage is higher than the threshold set with P17.13.
The panel temperature is higher than threshold set with P17.06.
The calculated capacitor current overload is higher than threshold set with P17.08
and/or P17.09.
A no-voltage release has occurred on the line voltage inputs, lasting more than 8ms.
The RMS current measured by the MCP5 module n is higher than threshold set with
P18.n.06.
The current THD measured by the MCP5 module n is higher than threshold set with
P18.n.07.
The slave nr. X does not communicate with the master. Check the RS-485 wiring.
Clean the air intake filter of the ventilation system.
Check the currents for each step, the efficiency of the fuses and contactors.
Perform the operations in A20 and A21 and check the capacitors conditions or
contact technical service.
