When under frequency protection is activated, the RED
LED will light up.
3.5 DROOP
Droop adjustment. When paralleling, the AVR
compensate the input rating and voltage shifting basis
on load current, through internal circuit calculation and
increase or decrease the voltage. When phase current
lag the voltage, it decreases original voltage setting
and if the phase current lead the voltage then it
increases the original voltage setting. The increase and
decrease range can be preset by the DROOP
adjustment.
3.6 TRIM
Analogue voltage Input sensitivity. When terminal A1
and A2 is added with a DC input (0
10V), the TRIM is
used to adjust the influence level from the DC input to
the rated voltage. If the TRIM potential (POT) is
adjusted fully counter-clockwise, and then the
additional signal will not cause any influence. On the
contrary if the TRIM is adjusted fully clockwise, then
the additional signal will produce a maximum effect.

WARNING
Please make sure you have read and understand
the contents of the instruction manual prior to
installation. Incorrect wiring connection may
result in irreversible damage to the product and
other equipments.
This Automatic Voltage Regulator is not equipped
with loss-Sensing Protection function / Over
Excitation Protection. An additional Over-Voltage
Protection device for load may be required to
avoid possible damage to the equipment or
severe personal injury or death.
