13 PHASE I [L1]
14 PHASE V
[L1-N]
Phase correction between voltage and current in the measuring system. (refer p.6)
15 C-TEST
The power of the particular capacitor stage is calculated during each switching
operation and compared with the stage output of the capacitor. If the result varies
from the nominal value, an error message is generated. This test can be stopped
here. In coupling-mode C-TEST is inactive!
16 C-FAULT (+)
( -)
The deviation from the rated value of the capacitor, for a fault message is generated.
17 TEST ATTEMPTS
When at least this number of successive measurements has resulted in a fault in the
capacitor power, a C-fault message is output.
18 OUTPUT 1. STEP
The range for entering the stage output can be increased to [0...25500] here
(e.g. for high-voltage measurement)
19 CONTROL
The measuring system of the controller is based on a single phase measurement.
3-phase CAP (factory setting): The measurement is converted and all outputs are
displayed 3-phase (presuming symmetry in the grid).
1-phase CAP: Display and control is only performed for the measured 1-phase value
(for example 1-phase compensation in non-symmetric grids)
3-phase IND: set-up of an inductive compensation with reactors possible (3- phase)
1-phase IND: set-up of an inductive compensation 1-phase
3-phase C/I : Mixed compensation possible (CAP/IND)
1-phase C/I : (Realization according separate application solution)
20 SUPPLY Setting of the controller in case supply of electric power takes place
[1] --- (no reaction) factory setting
[2] switch-off stepwise
[3] total switch off
[4] 2.cos-Phi
21 DISPLAY [cos
Switch over between cosinus or tangens
22 PASSWORD CHANGE?
The password for ExpertMode can be changed here. All combinations of letters
and figures are possible
27 ERROR - DISPLAY BACKLIGHT
If an error or warning message appears in the display -the backlight can change
to red light for better attention. (modification: OFF/ white/ red/ pink)
28 CT - OFFSET
The here selected value will be added to the „primary CT"-value (in Programming/
item 1) Therefore all possible CT-ratios are possible.

Adjustment of current phase position
Selection of phase of current transformer
Between which conductors has the measuring voltage of the
controller been connected:L-L resp. L-N of all phases possible.
