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



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.

※Use only the replacement fuses specified in this user manual.
