It has single and three phase sensing. RD1 is powered by an auxiliary circuit on the main stator. The RD1 controls and keeps constant the average value of the 3RMS phase voltages. A frequency measuring circuit continually monitors the alternator output and provides output under- speed protection of the excitation system, by reducing the output voltage proportionally with speed below a pre-settable threshold.
- an external voltage setting output selection DIP switch - electric protection with fuse. The electronic is sealed with resin (it is a perfect protection against vibration and humidity). SINCRO® is a brand of Soga Energy Team ITALY | sogaenergyteam.com | info.sincro@sogaenergyteam.com...

The second group (group 2) of DIP switches selects: The possibility to set generator output by External voltage (Ext V, ON) The possibility to set generator output by External Potentiometer (Ext P, ON) SINCRO® is a brand of Soga Energy Team ITALY | sogaenergyteam.com | info.sincro@sogaenergyteam.com...
UNDER FREQUENCY KNEE ADJUSTMENT AVR RD1 incorporates an underspeed protection circuit (UF) which gives a volts/Hz characteristic when the alternator speed falls below a presettable threshold known as the "knee" point.

“POT”. Connect half voltage range (5 Vdc) on “EXT” “POT” input. With V trimmer adjust alternator voltage to nominal value for that range. SINCRO® is a brand of Soga Energy Team ITALY | sogaenergyteam.com | info.sincro@sogaenergyteam.com...

The L line is protected by fuse (type F8 A, 250 V, T 5x20). For the three phases alternator the voltage reference must be connected as follows: U-V-W are the three phases of the alternator. N is the neutral SINCRO® is a brand of Soga Energy Team ITALY | sogaenergyteam.com | info.sincro@sogaenergyteam.com...

For the single phase alternator the voltage reference must be connected as follows: U1-V1 are the output of the alternator (230 V). U1-U2 is half phase (115 V). The external voltage potentiometer: - At terminals “Ext” and “Pot”. SINCRO® is a brand of Soga Energy Team ITALY | sogaenergyteam.com | info.sincro@sogaenergyteam.com...
6. Carefully turn volts trimmer “V” (or external pot, if fitted) clockwise until rated voltage is reached 7. If instability is present at rated voltage, refer to stability adjustment, and then re-adjust voltage if necessary SINCRO® is a brand of Soga Energy Team ITALY | sogaenergyteam.com | info.sincro@sogaenergyteam.com...
Adjust UF limit to a value close to the nominal frequency FUSE BLOWS low frequency (so the fuse burn during CONTINUOUSLY the turn-off procedure) Replace the AVR - Faulty AVR SINCRO® is a brand of Soga Energy Team ITALY | sogaenergyteam.com | info.sincro@sogaenergyteam.com...
