Reactive Power Controller

Display and use

In the front side of Prophi there is a digital indication
and three keys, with which you can question data and
program the device.
If you are in automatical mode, you can change be-
tween the operating modes using key 1:

automatic mode,

manual mode,

standard programming and
expanded programming

In standard programming often needed settings are car-
ried out such as current transformer ratio or the number
of stages.
In expanded programming those settings are carried out,
which are used not as often, such as discharge time or
choke degree.
To reach the expanded programming from automatic
mode, leaf through the standard programming using key
1 until the symbol "Prog" appears. Confirm selection
with key 2, and you are in expanded programming.

Automatic mode
Automatic mode is marked by the symbol
In automatic mode, there is:
- the switching condition of capacitive stages,
- the actual value of cos(phi) indicated,
- Connection and disconnection of capacitive stages,
- all 15 minutes saving of
peak and lowest values,
number of switchings of the capacitor stages and
the switching times of capacitor stages.
- Indication of measured values using key 2 and 3.
There are three possibilities to reach automatic mode:
- after net return,
- pressing key 1 for about 2 seconds,
- pressing no key in programming mode for
1 minute.

Automatic mode
Manual mode
In manual mode, you can switch in capacitor stages
using key 3, and switch off capacitor stages using key
2. The time between two switchings is only limited by
the programmed discharge time. If one stage shall be
connected in manual mode and a discharge time is run-
ning, the number and capacitor stage is flashing.
If no capacitors are switched in manual mode, an
automatical jumpback to automatical mode is carried
out after 15 minutes.
