Leroy Somer R230 AVR

* The alternator with shunt excitation is self-excited with an R230 voltage regulator.

* The regulator monitors the exciter excitation current as a function of the alternator output voltage.

* Very simple in design,the alternator with shunt excitation has no sustaining short-circuit capacity.

* Voltage Regulation:around +/-0.5%

* Voltage supply/sensing range 85 ~139 V (50-60Hz)

* Rapid response time (500 ms) for a transient voltage variation amplitude of ± 20%

* Voltage setting P1
* Stability setting P2.

* Initial potentiometer settings :

1) P1 potentiometer (AVR voltage adjustment): fully anti-clockwise.

2)  Remote voltage adjustment potentiometer: centre position.
Run the alternator at its rated speed. If the voltage does not
increase, the magnetic circuit should be remagnetized (see
section 2.3).

3) Turn the AVR voltage adjustment potentiometer P1 slowly
until the output voltage rated value is obtained.

4) Adjust the stability setting using P2.

5)  Sealed potentiometer P3 is factory set at 48 Hz for 50 Hz
and 58 Hz for 60 Hz
