WARNING
1. Some generators even when working at high voltage are factory set to sense at lower voltages.
Remember to set the DIP SW 2 to the sensing voltage not the working voltage of the generator even do
sometimes it can be the same. If you have a 480/277V generator but you have the sensing wires C and A
connected to 240 Volts move DIP SW 2 to ON
Another example are rental units with multi-voltage output with a switches for Y, YY, Delta & ZZ output,
but sensing is always at 240V from T7 and T9 even though the generator is running sometimes at
480/277V.
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. 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.

ATTENTION
1. Only qualified technicians should install and operate the AVR.
2. The voltage regulator may be installed at any suitable location on the generator set (dimensions are
shown in Figure 1). It is recommended that unit is mounted vertically with the green resistors on the
regulator upwards to achieve the best cooling effect.
3. All AC voltage sensing readings are average value only.

SECTION 3 : DIP SWITCH SETTINGS, LED INDICATORS AND ADJUSTMENTS
VOLT Voltage Adjustment
The adjustment range is set by
SW2.
U/F Under Frequency Protection
50 Hz system preset at 45 Hz,
60 Hz system preset at 55 Hz,
To change the setting, see the
Adjustment Step 3.
U/F LED
Under Frequency Protection status.
A：Sensing Input terminal
A to C: 170 –520 Vac
F+ , F-：Connect to generator
excitation field.
B：Power Input terminal
B to C: always less than 300 Vac
C：SensingInputandPowerInputterminals
EXT.VR Ext Potentiometer,
1K ohm 1W. Keep shorted when
not in use.
ADJUSTMENTS AFTER GENERATOR IS STARTED :
1. First, turn VOLT and STAB trimpots fully counterclockwise before starting the generator. Set the engine
governor to 50 or 60 Hz. Start the generator and wait till it reaches rated speed. Now slowly turn VOLT trimpot
clockwise to increase the working voltage. (If you use an external potentiometer, set it to the center position).
Keep EXT. VR shorted when not in use.
2. Next, slowly adjusting the STAB trimpot etting (clockwise), this change the response time of the AVR to
changing loads. If the setting is too high the voltage is unstable but if set too low the response is sluggish. We
recommend using an analog DC voltage meter on F, F+ and adjust STAB for the lowest amount of voltage
fluctuation (needle movement).
3. Last, Under Frequency (U/F) adjustment. (The U/F is Factory preset and needs no adjustments) put in rare
applications. Use the U/F LED as a guide. When this LED is ON the circuit is operational turning off the
regulators output. To recalibrate, adjust the generator speed to the new U/F kneel point, usually 5 Hz under
rated speed (Hz) then set the U/F trim-pot to the point at which the U/F LED just changes from off to on rated
speed (Hz) then set the U/F trimpot to the point at which the U/F LED just changes from off to on. Adjustment
range for 50Hz system is 40 to 51 Hz. For 60 Hz system the range is 50 to 61 Hz.
Over Excitation (O/E) LED
When the excitation voltage is greater than 35%
of input power voltage, the LED will lit after 5
sec. If the DIP switch SW3 set at OFF then it will
also shut off excitation output at the same time.
DIP Switches
System Freqency SW1 ON:50 Hz, OFF:60 Hz
Sensing Input SW2 ON:220V, OFF:440V
O/E Protection SW3 ON:Disable, OFF:Enable
STAB Stability Setting
With No Load, slowly turn the
STAB counterclockwise until
voltage becomes unstable then
turn clockwise about 1/5 turn.
