Problem
The AVR does not work.
The AVR is on, «
Пере
-
грузка
» LED does not go
o
ff
and there is no output
voltage.
The AVR emits repeated
clicks, though «

» LED lights up.
The AVR has disconnected
the load. «
Перегрузка
»
LED is on.
Cause
1. The power switch is o
ff
.
2. There is no voltage in the mains
socket.
3. Too much load is connected.
1. Failure of the testing scheme.
2. The AVR is faulty.
The input voltage is very unstable.
The input voltage is too high.
Solution
1. Press the power switch again.
2. Make sure there is input
voltage.
3. Disconnect a part of load.
Switch the AVR o
ff
and on again.
If the problem is not solved,
address a service center.
It is normal. The AVR is
regulating the output voltage.
When the input voltage reaches
150–280 V, the AVR will resume
its operation.
If none of the above methods can solve the problem, please seek professional advice at your
nearest service center. Never attempt to repair the product yourself.
5. INSTALLATION AND OPERATION GUIDE
•
Connect the load to output sockets of the AVR.
•
Connect the AVR to a 220V power line.
•
Switch on the power switch. The indicator built into the switch will light up. «
Стабилизатор
»
(Regulator) LED will light up for a short moment, and «
Перегрузка
» (Overload) and «
Сеть
» (Line)
LEDs will be on during the whole self-testing.
•
After a 10-second self-testing, «
Перегрузка
» (Overload) LED will go o
ff
, «
Сеть
» (Line) LED will
light up and the voltage will be connected to the output sockets. If «
Перегрузка
» (Overload) LED
doesn’t go o
ff
after testing, it’s forbidden to operate the AVR until the trouble is shot.
•
When the AVR operates to boost or buck input voltage, the «
Стабилизатор
» (Regulator) LED
lights up.
•
In case of overload or short circuit at the output, the AVR will disconnect voltage supply. After the
cause of overload is removed, switch on the AVR again by pressing the power switch.
•
If the input voltage increases over 280V or falls lower than 150V, the AVR will be disconnected, and
«
Перегрузка
» (Overload) LED will be on.
