3.1 Voltage Adjustment
The generator output voltage can be altered by adjustment of the volt VR on the AVR board, or by the external trimmer (1KW) if fitted.
- The terminals 1&2 must be linked if no hand trimmer.
- Before start the generator, please turn the Volt trimmer on the AVR board fully anticlockwise Turn the external trimmer to midway position.
- Turn the stability trimmer on the AVR board to midway position.
- Connect a voltmeter to generator output voltage terminals.
- Start generator set and run on no load at nominal frequency 50 ~ 53Hz or 60~63Hz.
- If the red Led is illuminated, refer to the under frequency roll off adjustment.
Carefully turn volt trimmer clockwise until rated voltage is reached.
