SSUE
The controller fails to switch on
(all leds and/or display are
switch off)
The controller fails to switch in
the capacitor banks
The controller displays an unreal
power factor
The controller switches in all the
capacitor banks without
increasing the power factor on
the display
The controller switches the
capacitor banks in and out
continually, without finding a
balance
If none of the previously described possibilities occurs or if it is not possible to detect the fault, ask for
assistance.
For any queries (including the request for spare parts, please contact.
Before contacting the Technical Service department, make sure to have carefully checked that the
instructions provided with the technical manual have been complied with. If it is necessary to contact the
Technical Service department, the following data regarding the unit must be available:
Customer's details
-
N° of delivery bill or invoice.
-
Nameplate data given on each product.
-
Characteristics of the current transformer used (current transformer power rating and ratio).
-
List of malfunctions found and checks already made.

P
ROBABLE CAUSE
Disconnect switch not on.
Control circuit fuses blown.
Quick connect terminal boards located
inside the unit disconnected.
Faulty controller
Current transformer installed at
incorrect point of the system, only
upstream of the power factor correction
system.
The current transformer is enabled on
the incorrect phase.
The controller is set to manual mode.
The current transformer amperage is
lower than the sensitivity threshold
The current transformer is enabled on
the incorrect phase.
The current transformer is faulty.
The controller is faulty.
Current transformer installed at
incorrect point of the system, only
upstream of the load, but downstream
of the power factor correction system.
The current transformer is enabled on
the incorrect phase
Faulty setting of the controller
parameters.

Turn the disconnect switch on.
Identify the cause blowing the fuses,
then replace them.
Correctly engage the quick connect
terminal boards on the controller.
Check the controller power supplies. If
they are regular, replace the controller
with an original spare one.
Correctly position the current
transformer upstream of all the loads
and power factor correction.
Position the current transformer on the
phase L1 (R) referred to the unit.
Switch to automatic mode of operation.
Increase the load current or use a
current transformer with suitable
primary ratio.
Position the current transformer on the
phase L1 (R) referred to our cabinet.
Replace it with a suitable one.
Replace it with an original spare one.
Correctly position the current
transformer upstream of all the loads
and power factor correction.
Position the current transformer on
phase L1 (R) referred to the unit.
Check current parameters and set them
correctly.
