6. OPERATION
NOTE: DELAY only takes effect when the system is restarted into normal.
HOME MAIN SOCKET
Before use, please make sure the voltage and power of the appliance are
accord with the labeled power and specification of the unit to avoid any damage.
Please connect the appliance before turning on the unit. Switch on appliance
after you make sure the unit is working normally with output voltage.
When connecting the electrical appliance with motor or compressor, such
as drill, air-conditioner and so on, to the automatic voltage regulator,
please make sure that the power rating of the automatic voltage regulator
is at least 3 times of the power rating of the electrical appliance, so that it
can work smoothly, because the starting up power is much beyond of the
power rating of the electrical appliance.
Output Delay: Delay time 6 seconds (DEFAULTED) and 120 seconds
(MANUAL SWITCH) are alternative.

7. LOW & HIGH VOLTAGE PROTECTION
When output voltage is lower or higher than labeled voltage, AVR will turn
into self-protection state automatically ,the UNUSUAL RED indicator
flashes every one second and output voltage will be cut off.
When output voltage comply with labeled voltage, AVR will go into
automatic recovering state, the UNUSUAL RED indicator extinguishes.
Then DELAYING ORANGE indicator flashes every one second, the
system goes into delaying state. After delay, DELAYING ORANGE
indicator extinguishes and output voltage resume .
10. WITH COOLING FAN
When the temperature of transformer excessed 90℃+/-5%, the cooling
fan will switch on automatically to low down inside temperature and will
stop working while the temperature comes down.
NOTE: This function only suitable for 3KVA , 5KVA
11. OUTPUT CAPACITY
The automatic voltage regulator will switch off automatically if the total
wattage of the electrical appliances exceed the automatic voltage
regulator output capacity.
9.OVERLOAD PROTECTION
When avr is overload, the system will turn into self-protection, red led
indicator will illuminate continuously and there is no output. To resume
the output, you should lessen the load and then restar the unit.
NOTE: This function only suitable for 3KVA / 5KVA
NOTE: No overload Protection is equipped in standard configuration,
users should notify manufacturer and take special order if this function
is required.
8. THERMAL PROTECTION
NOTE: No overheating Protection is equipped in standard configuration,
users should notify manufacturer and take special order if this function
is required.
When the temperature of the transformer exceeds 130℃+/-5% , the
system will automatically turn into self-protection state, UNUSUAL RED
indicator will flash every one second and output voltage shut down. While
temperature is lower 70℃+/-5% , the system will recover automatically.
UNUSUAL RED indicator will extinguish, and output resume.

If this voltage is in the range of 190-250V, the regulator provides the
100% listed maximum output power. maximum output power will change
as the curve shown below.

On the rear panel of the automatic voltage regulator there is a terminal fitted
with a nut. This terminal is connected to the case of the automatic voltage
regulator and also to the earth terminal of the AC output socket. The use of
this terminal will depend on your particular installation. In any installation,
heavy duty, green-insulated wire should be used for this connection.

NOTE: The earth terminal of the AC outlet is connected to the neutral terminal.
This is the same as a standard household power point where the neutral line is
bonded to earth and there is normally no voltage between them.
In a stationary land based installation, the earth terminal should be
connected to a metal earthing stake driven into the ground to a depth of
1.2m or more.
In case of trouble with the AC output, e.g.short-circuit, overload, etc... the
protection circuit will automatically cut off the output.
In such cases:
(A) switch off the power at once
(B) disconnect all units
(C) check the connected devices
(D) use the unit again unless the problems
concerning the connected devices have been solved
When in use for a prolonged period of time, the AC output may suddenly be
cut off although the input voltage normal, This may be caused by excessive
temperatures. If this happens. Please proceed as follows:
(A) Switch off the automatic voltage regulator at once
(B) Disconnect some of the appliances or wait until the automatic voltage
regulator cools off
(C) Switch the automatic voltage regulator back on

15. EXPERT OF PROTECTOR FOR
Make sure that the to tal laden power does not exceed the listed maximum
output power of the regulator.
Be sure to connect the ground point to the ground for your safty.
Always keep the automatic voltage regulator in an environment which is:
(A) Well-ventilated
(B) Not exposed to direct sunlight or any other heat source
(C) Inaccessible to children
(D) Safe from water/moisture, oil or grease
(E) Safe from any flammable substance
WARNING: DO NOT DISASSEMBLE THE UNIT. HAZARDOUS VOLTAGE! DANGER!
PLEASE RETURN TO THE DEALER IF YOU FIND ANY PROBLEM WITH THE UNIT

14. MAINTENANCE
Very little maintenance is required to keep your automatic voltage regulator
operating properly.
You should clean the exterior of the unit periodically with a damp cloth to
prevent accumulation of dust and dirt. At the same time, tighten the screws
on the AC input terminals.

Avoid overloading
Do not use the regulator beyond its maximum power.
When connected to any appliance with built-in motor compressor, the
starting power is generally several times of the appliance's listed power
rating. Make sure that the total starting power capacity of all connected
appliance does not exceed the listed maximum output power of the
regulator. For color TV, calculate it twice as its listed capacity.
Make sure that the regulator is of the same output voltage and frequency
as the appliance's it connected.
Make sure that the voltage of electrical source is within the listed range
of the input voltage of the regulator.
Always place the regulator in an environment that is:
(A) Well ventilated.
(B) Not exposed to direct sunlight or heat source.
(C) Out of reach from children.
(D) Away from water moisture oil or grease.
(E) Away from any flammable substance.
