ASYMMETRY FACTOR
-127...127
ASYMMETRY FACTOR of switch interval. The factor is the ratio
between switch interval for switching on and switching off. Switch
interval for step exchange is not affected by this setting.
X= 1 = equal
X = +2 to +127: delay switching off = switch interval multiplied by X
X = -2 to -127: delay switching on = switch interval multiplied by X

Q CAPACITIVE STEPS TURN OFF
Yes/No
"YES" As soon as a capacitive condition is recognized, the controller
switches off without keeping the switching time, the necessary step
power in order to prevent leading network conditions.
"NO" The controller works only with the set target COS φ.

In the step database, all settings and data are combined which are required to adjust and
adapt the steps.

DISCHARGE TIME
5...1200 s
The discharge time is defined once and is valid for all steps. The
discharging time is a blocking time, becoming active after switching
off a step. As long as this time is running this step is not available for
the regulation. Discharging time should be adapted to the capacitor
discharging unit.

STEP NOMINAL VALUE
Ct*Pt*7000
If STEP RECOGNITION is not active, it is required to do this setting,
to get proper function of the relay. The size of the capacitors can be
programmed manually in kvar. Before this programming, CT
FACTOR and NOMINAL VOLTAGE must be programmed correctly. A
change of CT FACTOR or NOMINAL VOLTAGE is automatically
changing the value of the capacitor size.
The programming can be done for each step individually in kvar. So
there is no special sequence necessary. A step can be programmed
as a capacitor (c) or as an inductor (i).
