AVR DCout bias
[ % ] (FV)
AVRi voltage output bias level. This is a basic voltage level of the output if there is no regulation loop active.
Step:
0,1 %
Range:
0 – 100,0 %
Force value possibility: Yes
Hint:
Real voltage level depends on AVRi outputs connection and output level potentiometer setting. Maximum
range is
±
10 V.
TauVoltActuat
[ s ]
Time constant of the voltage regulator connected to the binary Up/Down outputs. This is to match the
reaction of the controller‘s regulator with the actual reaction time of the voltage regulator.
Step:
0,1
s
Range:
1,0 - 300,0 s
Force value possibility: Yes
Hint:
Use this for older generators where motorised potentiometer is used for voltage adjust to the AVR.
Volt/PF control adjustment
IG-AVRi output connection
Every time refer to corresponding AVR manual before interface connecting. Use no droop AVR.
IG-AVRi-TRANS (AC power supply for AVRi) has to be supplied from gen-set voltage.
AVRi outputs can be connected as symmetrical: OUT1-OUT2 or unsymmetrical OUT1-OCOM or OUT2-
OCOM.
•
Potentiometer on the AVRi defines maximal OUT1, OUT2 voltage range.
•
Use symmetrical (OUT1,OUT2) AVRi output to connect the AVRi to AVR auxiliary voltage input.
•
Use unsymmetrical output if an external AVR potentiometer has to be replaced with AVRi.
•
AVRi output voltage should change generator voltage typically in range
±
10 % of Nominal voltage.
•
For more details please refer to Installation guide – chapter AVR interface examples.
