SECTION 4 : ADJUSTMENT AND SETTING
4.1
TRIM works together with a bias voltage applied
to terminals A1 and A2. This signal is supplies by
an external Power Factor Paralleling PLC. Use
the TRIM potentiometer to adjust the DC voltage
input that controls the level of the generator
’s
output voltage. When set counter-clockwise the
control level is zero, and if moved clockwise the
maximum control range is 10%. The signal
connected to A1 and A2 can be unipolar (0,+) or
bipolar (+,
). Check with the manufacture of the
Paralleling control PLC.
4.2
DROOP
:
Select switch K or L pending on the
secondary current of the CT that you are using.
Voltage droop works when the CT and the AVR
senses that the output of the generator voltage
and current waveforms are out of synch and the
AVR droops the output voltage of the generator
to correct it.
4.3
STAB
:
If the generator output voltage oscillate,
adjusting the STAB potentiometer will stabilize
the output voltage, over adjustment will result in
high voltage variation when load is applied. Use
an analog type multimeter when making this
adjustment. Connect the meter to terminals F+
and F- and slowly adjust STAB potentiometer to
the point when the pointer stops moving.
4.4
VOLT
:
Move to set the generator output voltage.
Set DIP Switch 1 to the generator working voltage.
Set SW1 to OFF (220V) for use from 170 to 260 Vac
Set SW1 to ON (440V) for use from 340 to 510 Vac
When using and external VR set it to the central
position and adjust the AVR VOLT trim to the
rated voltage.

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. Secure all wiring connection. Do not install AVR at a
place with high vibrations to prevent loose connections.
For safety do not touch the heat sink while in operation.
4. Terminal
:
“Fast-On” terminals 6.35mm (1/4 inch) & With
4mm crimping terminal.
5. 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.
6. Turn off O/E in AVR when paralleling.
