Fix stages
The first three capaci-
tor stages can be fixed
switched in alterna-
tively. Fix stages are
marked by a line be-
low the number of the capacitor stage.
Fix stages cannot be included in the controlling. Never-
theless they are considered in the stage ratio, so that in
the stage ratio in the most disadvantageous case (three
fix stages) in the standard programming only two stage
ratios are available. To get a better solution of the stage
power, the capacitor power must be set for every single
stage in the expanded programming .

Expanded programming
In the expanded pro-
gramming those set-
tings are carried out,
which are required
very rarely.
With key 3 you can change between the indications.
With key 1 the selected indication can be chosen for
changing.
The following settings and readings can be carried out in
expanded programming:
Fix stages,
Discharge time,
Disconnection pause of relay stages,
Power station service,
Stage power, 1. - 2. stage,
Choke degree,
Voltage transformer ratio,
Harmonic table,
Switching frequency of transistor stages,
Alarm calls,
Averaging time for reactive power,
Averaging time of the mean value cos(phi),
Fan control,
Overtemperature disconnection,
Indication in manual mode,
Password,
Contrast,
Reset of programming,
Connection configuration,
Software release and
Serial number.Power station service,

With key 3 you switch
in the fix stages.
With key 2 you dis-
connect the fix stages.
Confirm selection with
key 1 and continue with expanded programming using
key3.
