Section 4: DISPLAY - FUNCTIONS
After the operating voltage has been switched on, the BR7000 briefly indicates with
description and software-version before changing to automatic operation.
Actual values and symbols of the particular operation state are shown in the display.
In the automatic operation (standard) capacitor steps are automatically switched on or
off to reach the pre-set target cos-phi. This happens when the required reactive power is
higher than the value of the smallest capacitor step.
Example 1: Automatic operation

- 8 -
Number of switching outputs until end stop.
Here: 15 three-phase capacitors, end-stop: 15
Control direction is symbolized by a
compact arrow:
Connecting-in
Connecting-out
The connecting-in arrow is always
located after the maximum possible
number of stages (end stop)
An open arrow indicates that the
required blocking time (Discharge time)
is running before an impending
switching step
A double arrow symbolizes switching of
several branches
The sigma-sign indicates the three-
phase-value (mean-value) resp.
activated three-phase-capacitors
Alarm relay activated
(declines in case of error)
Message relay activated: “SUPPLY”
Message relay activated:“Undercurrent”
Message relay aktivated: “Harmonics”
FAN-relay: ON
The particular capacitor outputs are
permanently monitored. Inverse display
