This document is the operation manual for EA06-220V generator automatic voltage regulator.
This manual provides detailed instructions for installing, wiring, and operating the KUTAI EA06-220V automatic voltage regulator. It covers wiring configurations for single and three-phase systems, voltage and frequency adjustment, and circuit protection settings. The regulator includes three sensing inputs, adjustable under-frequency and over-voltage protection, and LED indicators for status. It is compatible with Mecc Alte UVR6 but is not a genuine Mecc Alte product. The manual also includes troubleshooting steps for field flashing and maintenance tips to ensure proper operation and prevent damage. This manual is written in Chinese.

The sensing input voltage range is 170 − 280 Vac / 270 − 520 Vac.
Bridge the 60 Hz terminals to set the frequency to 60 Hz; remove the bridge for 50 Hz.
The yellow LED indicates over excitation.
Shut down the generator, disconnect wiring, flash the field for 3 seconds using a 3–5 ohm resistor for full wave or 5–10 ohm for half wave AVR.
