3. Setup instructions
3.1. Stator voltage and current measurement
For the plate to work correctly, the stator voltage and current measurement on both AVRs
must be identical. For generators with an unbalanced load, using different phases can
result in a measurement fault and a bump in regulation on switching from one AVR to the
other.
For generators where only one stator current measurement transformer is used, it is possible to put stator
current measurements on both AVRs in series.
3.2. Configuration files
The configuration of both AVRs must be identical, apart from choosing one to be the "master" and must
correspond to the technical and electrical data of the generator on which the plate is to be installed.
It is therefore important to pay particular attention to the following settings:
•
Generator power, rated voltage, frequency and power factor
•
Voltage transformers for generator voltage sensing
•
Voltage transformers for mains voltage sensing
•
Current transformer for stator current measurement
•
Setpoint adjustment values (voltage, power factor, kVAr - depending on the application) and all types of
applied corrections (pushbuttons, potentiometer, etc.)
•
PID coefficient values
•
Limitations
•
Input and output configuration
CAUTION, DO NOT OVERWRITE ONE AVR CONFIGURATION WITH THE OTHER AVR
CONFIGURATION
Using the EasyReg Advanced program, selection of AVR redundancy can be found in the "Configuration" menu,
then the "Wiring" page. Click on the "Redundancy second D700" box. The following message appears:
Click "Yes". A second message appears:
