Troubleshooting

Fault: The controller does not switch
on or off steps although there is a
considerable variable inductive load.

Solution

• Check that the controller is in automatic

Mode.

• Check setting of phase shift and C/k.

• Check that the CT short-circuit bridge is

removed.

Fault: The controller does not seem to
activate any steps.

Solution

Wait for the delay time between switching
and/or the power outage delay time.

Fault: One of the indicators flashes.

Solution

Normal situation when the actual inductive
current varies around the set sensitivity (C/k).

Fault: The preset power factor is not
achieved.

Solution

At low or no load, a low power factor can
correspond to a very small inductive current.
The corresponding capacitor steps are too
large for compensation.

If the average cos

ϕ

over a period of time is

too low, the preset cos

ϕ

may be increased.

Fault: All capacitors are switched on
although the required reactive power is
relatively low.

Solution

Check setting of phase and C/k values.

Fault: The controller is connected but
does not work (nothing on display).

Solution

Check the voltage setting.

Fault: The AutoSet procedure stops and
the controller displays an error messa-
ge ‘FXX’.

Solution

Please identify the meaning of the error
message (see following table) and act
accordingly.
