CONNECTION OF THE LINE CURRENT TRANSFORMER
Mount the current transformer on the phase not 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 equal to at least 6VA. If other loads are
present in parallel to the current transformer, check their power consumption and increase the apparent power if
necessary. When the distance of the current transformer from the unit is less than or equal to 20mt, use 4mm
cables for the connection; if not, increase the size of the cables (for further information, consult the Service
department).

MEANING
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 lasting more than 8ms has occurred
on the line voltage inputs
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 each step current, fuses and contactors.
Perform the operations in A20 and A21 and check the
capacitors conditions or contact technical service.
