Automatic Voltage Regulator
• When the self-test is complete LED “Delaying/Protection“ will go out and voltage connection
tothe output receptacles will happen. If the LED “Delaying/Protection“ at the end of the test
didnot go out, it is prohibited to operate the regulator to eliminate the problem.
• “Regulating“ LED will light when the regulator to increase or decrease in the input voltage.
• In case of overload or short circuit the thermal fuse is ready installed on the rear wall istrig-
gered. Turn on the stabilizer after removing the cause of the overload by pressing thepower
button.
• When voltage input is more than 285 V or below 184 V regulator will disconnect the load. “De-
laying/Protection“ LED will light up.
• “Delaying/Protection“ indicator will light up in case of overheating auto-transformer, protec-
tion will work. The load deenergises. After cooling down auto-transformer load power is re-
stored automatically.
6. TROUBLESHOOTING
Problem Cause Solution
The stabilizer does not turn
on voltage.
1. Switch is o.
2. There is no voltage
inthemains socket.
3. Excessive load is connected.
Triggering of protection fuse.
1. Turn on the switch.
2. Make sure there is input
voltage.
3. Disconnect a part of load.
Turn on the protective fuse.
Stabilizer turned on wherein
thelight does not go out
“Delaying/Protection”
andthere is no output
voltage.
1. Test curcuit crash.
2. Overheating
oftheautotransformer.
1. Switch the AVR o
andonagain. If the problem
is not solved, address
aservice center.
2. Wait until the product cools
down.
Voltage regulator keeps
clicking with constant
blinking of“Regulating” LED.
Input voltage is very unstable. It is normal. The AVR
isregulating the output
voltage.
Stabilizer disabled load.
“Delaying/Protection”
and“Regulating”
indicatorsare on.
The input voltage is too
low/high.
When the input voltage
reaches 184–285 V, the AVR
will resume its operation.
If none of the above methods can solve the problem, please seek professional advice at your near-
est service center. Never attempt to repair the product yourself.
