C. Switch on the AVR
•
Put the
POWER SWITCH
to
"RESET"
position, the
LED DISPLAY
will light, the
DELAYING LED
will
light and blink . At the same time, the digital display will show the elapsing delay time. Generally delay
time is set at 6 seconds.
•
When the delay is finished, the
DELAYING LED
lights off, and the
LED DISPLAY
will show output
voltage supplying to appliances connected to the AVR.
•
Switch "ON" the appliances one by one.
In Case of Power Failure:
•
Switch "OFF" the AVR and all the appliances.
•
Repeat above steps when power is restored.
D. Display of Input Voltage and Output Voltage
•
The input voltage and output voltage will show in the
LED DISPLAY
after switch it on.
E. Overheat Protection
•
This AVR is equipped with a unique TEMPERATURE PROTECTION CIRCUIT designed to protect the
transformer, giving you longer and satisfactory use of the AVR.
•
If the internal temperature of the windings of transformer reaches the limit or above, the output will be
cut "OFF" automatically, and the OUTPUT LED DISPLAY will show "C".
•
When the internal temperature returns to normal range, output power will be restored. After the delay
time, the display will indicate output voltage.
F. Output Over Voltage Protection
•
This AVR is built in with a very specialized feature called OVER VOLTAGE PROTECTION CIRCUIT.
•
This special and unique circuitry is designed to protect connected appliances whenever the output
voltage is higher than the normal range.
•
If the output voltage is over the normal range, the output will be cut "OFF" automatically and the LED
DISPLAY will show
“V
↑
”.
•
Once the input mains power returns to normal range, the AVR will restore the output automatically.
G. Output Under Voltage Protection
•
When the output voltage is below the normal range, the output will be cut “OFF” automatically and the
LED DISPLAY will show
“V
↓
”
.
•
Once the input mains power returns to normal range, the AVR will restore the output automatically.
I. Delay Operation
•
This model is designed with a delay feature to protect appliances especially the appliances with
compressors(like air-conditioner, fridge, motor, pump,and etc). which should not be switched on
immediately after being switched off.
•
The delay time is generally set at 6/180 seconds selectable.
Select delay or undelay before switch on
the AVR.
•
Press down the delay button, then you select the delay, the delay time will be 180 seconds. After switch
on the AVR, wait for 180 seconds, then the AVR delivers output; Press up the delay, it means undelay,
under "undelay" status, the delay time is 6 seconds.
If you connect the appliances with compressors, we suggest that you select "delay" before
switch on the AVR.
H. Short Circuit Protection.
In case of a short circuit or overload, the POWER SWITCH (integrated with a resettable fuse
function) or OUTPUT FUSE will trip off to cut of the input power supply. The OUTPUT FUSE
should be replaced in case if will burn out.
The Power Switch with the resettable fuse function
must be resettled on the initial position.
•
Check if the AVR is overloaded, if so, please remove some loads.
•
Check if the appliances are short circuit, if so, please disconnect the appliances.
