Reactive Factor Controller CX plus

The step sizes may be too small.
Solution:
Enter the phase correction angle (SETUP/206) manually and switch on the control again
(SETUP/100/PFC or SETUP/310).
If the “Automatic initialisation” (AI) is not successful after several attempts, it is alternatively
possible to manually set the correct phase correction angle (SETUP/206). The step outputs
which are not occupied can be set manually (SETUP/100/OUt)
to the step type “
FOFF
”.
The control must be manually switched on again (SETUP/100/PFC or SETUP/310).
7)
Step outputs are immediately switched off again.
Possible causes:
The nominal value of a step saved in the step database is not correct anymore (after changing a
capacitor, the value must be entered manually again or the entire step database must be reset).
Step is defective
no step power identified during switching
Solution:
Check the fuses and power contactors.
(see chapter Step identification / defective steps)
8)
One or several steps were identified as defective.
No step power identified during switching.
Possible causes:
Steps are defective
Solution:
Change the capacitors
Fuses are defective
Solution:
Change the fuses
Power contactor does not switch anymore or contacts are defective.
Solution:
Change the power contactor
(see chapter
“Identification / resetting defective steps”)
9)
Frequent switching of the outputs
