2.4.17 COS PHI : U SET POINT 4
Defines target point 4 for the COS PHI : U / COS PHI : P control
SET POINT 4 uses the “COS PHI IND” when the measured voltage is at the level which is adjusted. In fac-
tory setting this point is used when 1.06 * NOM. V
2.4.18 SETUP
In this submenu advanced settings can be made for the BLR-Q(U). These settings are
necessary for individual parametring for special applications. 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 paramters which are also in Quickstart
SETUP. The following points explain the settings.

2.4.21 MEASUREMENT
2.4.21.1 CT-FACTOR
The CT FACTOR is the ratio of current transformer. (e. g. 1000/5 = ratio 200). At BLR-Q(U)3phase the CT-
Factor is used for all three current channels.
For current measuring a CT always have to be used!
2.4.21.2 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.
2.4.21.3 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 (0 and 2.4.21.8).
Independent of connection of the voltage measuring channel, nominal voltage is always the
phase-phase voltage

2.4.21.4 CONNECTION MEASUREMENT
CONNECTION MEASUREMENT the setting if measuring of voltage is connected between two phases or
between phase and neutral phase. It is normally detected automatically at every start of BLR-Q(U). This is
done by comparing the setting NOMINAL VOLTAGE and the real measured voltage.
