SECTION 2 : OUTLINE / SIZE / INSTALLATION REFERENCE
Unit : mm
ATTENTION
1. AVR can be mounted directly on the engine, genset, switchgear, control panel, or any position that will
not affect operation. For dimension reference, please see Figure 1.
2. All voltage readings are to be taken with an average-reading voltmeter Meggers and high-potential test
equipment must not be used. Use of such equipment could damage the AVR.
3. Terminal：“Fast-On” terminals 6.35 mm (1/4 inch).
4. Improper setting of under-frequency protection could cause the output voltage of the unit to drop or
become unstable under with changes in load. Avoid making any changes to the U/F setting unless
necessary.
5. Turn off O/E in AVR when paralleling.

SECTION 4 : ADJUSTMENTS
U/F Under Frequency Protection
Adjustment When generator speed falls
below the knee point, the under frequency
protection circuit will activate and the
voltage and frequency begin to decrease
in linear descend.
Select frequency 50 or 60 Hz according to
the generator in use.
LED Indicator lit up when the generator is
in U/F (Under Frequency Protection) and
O/E (Over Excitation Protection).
DROOP Droop Adjustment
When paralleling, the AVR increase or
decrease its voltage output, when
phase current leads or lag the voltage.
The increase and decrease range can
be preset by the DROOP adjustment.
TRIM Trim Adjustment
When terminal A1 and A2 are biased
with a DC voltage (010V), the TRIM is
then used to adjust the influence on the
output voltage of the AVR. If the TRIM
(POT) is adjusted fully counter-
clockwise, any bias voltage will not
cause any influence. On the contrary if
the TRIM is adjusted fully clockwise,
then any signal will produce a maximum
10% effect.
VOLT Voltage Adjustment
Generator rated output voltage
adjustment.
Must be in accordance with the
DIP Switch SW1-1 & 2 voltage
range setting.
DIP U/F Dip Adjustment
When U/F protection is activated, the
voltage droop ratio can be adjusted via
this DIP (POT). The adjustable range is
3  10 V/Hz.
STAB Stability Adjustment
Correct stability adjustment must be
conducted while the generator is
operating without load. First adjust the
STAB potentiometer (POT) anti-
clockwise until the voltage becomes
unstable, and then slightly adjust it
clockwise (About1/5 turn). When the
voltage just reaches the critical point
(Knee point) of stabilization, where the
voltage is stable yet very close to
becoming unstable.

ATTENTION
1. All AC voltage readings are Root Mean Square (RMS) value.
2. Use a remote 500 ohms 1 watt external VR for +/- 5% adjustment range. (keep shorted if not used)
3. Use a remote 1K ohm 1 watt external VR for +/- 10% adjustment range.
4. Sensing Voltage can be set from 220 –600 Vac Program SW1 & SW2 correctly.
5. For single phase sensing bridge E2 & E3 and move SW3 to ON.
6. If your PMG is not working you can also power the AVR in shunt using terminals P1 & P2 connected to
the output of the generator as long as it’s less than 277 Vac.
