Reset:
With the item Reset, it is possible to reset the programmed parameters of the controller. Here, the
programmable parameters are reset to default settings. A listing of the settings can be found in the
appendix Technical Data.
This has the advantage of all configured parameters to be deleted at once and the controller restarting
with the default settings stored.
Perform reset: Menu Extras, menu item Reset

8 Notes on detecting errors
Undercompensation, not enough stages are connected:
Check controller for error displays (refer to section 7.8). If the target CosPhi is set to 0.8 capacitive, the
capacitors need to connected one after another. If the facility is not over-dimensioned, almost all stages need
to be connected.
Undercompensation, all stages are connected:
The existing facility is not sufficient (e.g. due to new inductive consumers).
Please contact your local representative (extend your facility).
See the cover sheet of these operating instructions for the service telephone number.
Check the main fuse and group fuses of the facility. Checking the controller parameters.
The group fuses must display at least 1.7 times the value of the capacitor power.
If the fuses do not hold, despite their being correctly selected, the groups must be checked individually for
excessive current input and for defective contactors.
Overcompensation, too many stages are connected:
Check controller settings (target CosPhi capacitive?).
Transformer connected in the wrong position?
Controller switches a lot, in particular during low load (at the weekend, during the night):
Check programming of the transformer ratio.
Switch on a small stage permanently (manually), if required.
