Automatic Voltage Regulator
1. The switch is o
ff
.
2. There is no power in the
socket.
3. The automatic fuse has
activated.
4.The load connected is too
powerful.
The AVR is faulty.
Input voltage is unstable.
Input voltage is beyond
possible regulation range of
100-280 V.
7. PAUSE FUNCTION
•
Pause feature is designed to protect your equipment in case of frequent drops of power supply. It
is especially important for voltage consumers with electric motors or compressors. After power
supply has been restored, the AVR switches on in about 3 minutes. The pause LED
c
illuminates, if
this feature has been activated, i.e. Pause On/O
ff
button
d
is in the On position.
8. PROTECTION FROM HIGH INPUT VOLTAGE, OVERLOAD AND OVERHEAT
•
The
AVR is equipped with specially designed integrated automatic protection circuit against over-
voltage. If mains voltage is above 280 V, load is automatically cut o
ff
. If voltage is below 280 V, the
AVR automatically restores power to all connected consumers.
•
The
AVR is also equipped with overload/overheat protection feature. If the connected load is too
big, the transformer is heated and when certain temperature is reached, the load is cut o
ff
. After
cooling down, the AVR automatically switches on.
9. TROUBLESHOOTING
The AVR does not start.
The AVR switches on, but
there is no output voltage.
The AVR often produces a
clicking sound.
The AVR has cut o
ff
load.
High/Low voltage LED
illuminates.
1. Press the switch once again.
2. Make sure there is electric
power supply.
3. Disconnect part of the load
and switch on the AVR again.
4. Disconnect part of the load.
If the fault is not eliminated,
please address an authorized
service center.
It is normal. The AVR is regulating
output voltage.
When input voltage restores
within 100-280 V, the AVR
switches on automatically.
