To activate the motor-drive unit and control unit, proceed as follows:
► Switch on medium voltage (transformer is idle).
ð
The control unit starts automatically after a few seconds. The LED
flashes for 10 s to indicate the inrush interlock. After 10 s, this LED
lights up blue continuously.
ð The LED also starts by flashing and then lights up continuously as
soon as the internal energy accumulator is fully charged.
ð
If the LED is not lit up, then the control unit is ready.
ð If the red LED lights up and the E4 event code is shown in the dis-
play, the automatic adjustment was not carried out correctly.
6.3.7 Setting parameters
Set the most important parameters for commissioning the device in accor-
dance with your requirements:
1. P1: Set desired voltage [ ► Section 7.4.1.1, Page 76].
2. P2.1: Set bandwidth B1 [ ► Section 7.4.1.2, Page 77].
3. P2.2: Set delay time T1 [ ► Section 7.4.1.3, Page 78].
4. P3.1: Set bandwidth B2 [ ► Section 7.4.1.4, Page 78].
5. P3.2: Set delay time T2 [ ► Section 7.4.1.5, Page 79].
6. P4.1: Set undervoltage blocking [ ► Section 7.4.2.1, Page 80].
7. P4.2: Set overvoltage blocking [ ► Section 7.4.2.2, Page 80].
8. P5: Set blocking function [ ► Section 7.4.3, Page 81].
9. F5: Set inverting [ ► Section 7.4.13, Page 91].
ð
The most important parameters for voltage regulation have been set.
If you would like to set further parameters, follow section Configuring the
control unit [
► Section 7.4, Page 75].
6.3.8 Checking automatic voltage regulation
To check the automatic voltage regulation, proceed as follows:
1. Measure voltage on low-voltage side of transformer.
2. Press to activate the AVR MANUAL operating mode.
3. Press or as often as necessary until the measured voltage is be-
yond the range of the set bandwidth (desired voltage ± bandwidth).
4. Press to activate AVR AUTO operating mode.
ð After the delay time, the on-load tap-changer moves back into the
range of the set bandwidth. If this does not happen, check the voltage
regulation parameters [
► Section 7.4.1, Page 75] and repeat the test.
