SECTION 4 : ADJUSTMENTS
U/F
Under
Frequency
Protection
Adjustment When generator s p e e d 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.
