DISCHARGE TIME
For every single capacitor step an own discharging time can be defined. The discharging time is a blocking time, becom-
ing active after switching off a step. As long as this time is running (display of "!" in the step indication) this step is not
available for the regulation. Discharging time should be adapted to the capacitor discharging unit.
For step exits, which are switching thyristor switches, discharging time can be reduced to the zero.
2.5 SETUP
In this submenu advanced settings can be made for the BLR-CM. These settings are necessary for
application specific adjustments. To enter this submenu, please push the right button for 3 sec. It
is protected by a password (factory setting 2402).
The menu is divided into logical groups. In these groups you can find parameters which are also in Quickstart SETUP.
The following points explain the settings.
2.5.1 CHANGE LANGUAGE
Standard version of BLR-CM is supporting English, German and French.

See Chapter 2.4.5
2.5.3 MEASUREMENT
2.5.3.1
CT-FACTOR
The CT FACTOR is the ratio of current transformer. (e. g. 1000/5 = ratio 200). At BLR-CM3phase the CT-Factor is used for
all three current channels.
For current measuring a CT always have to be used!
2.5.3.2
VT-FACTOR
VT FACTOR is the ratio of the voltage transformer. If the regulator is connected directly to the measurement voltage
without VT the value 1 has to be used.
2.5.3.3
NOMINAL VOLTAGE
Function of the setting of nominal voltage is to make a definition about the nominal voltage of the system. The threshold
levels for under- and overvoltage are based on this as well as the ratings of the capacitor sizes in step database, which
are used for control and monitoring (2.5.3.7 and 2.5.3.8).
