5. Operation of the AVR

a. Connect the Electrical Appliances to Regulator

• Make sure all appliances are turned "OFF", and put the power switch of AVR to "OFF" position.
• Plug the AC mains cord of the appliances into the output socket of AVR, ensuring that the total starting power needed does not exceed the rated maximum output power of the AVR.

b. Connect Regulator to Electrical Mains

Plug the AC mains cord to the wall mains socket.

c. Switch on the regulator

1. Put the power switch to "ON" position. The yellow LED will illuminate and blink. At the same time, the digital display will show the elapsing delay time. Generally, the delay time is set at 6~10 seconds.
2. Then the yellow LED lights off and the green LED will illuminate.
3. The digital display will show the output voltage supplying to appliances connected to the regulator.
4. Switch "ON" the appliances one by one.

In Case of Power Failure:

• Switch "OFF" the regulator and all the appliances.
• Repeat above steps when power is restored.

d. Display of Input Voltage and Output Voltage

The digital display will show the input voltage and output voltage after the AVR is switched on.

e. LED Operation

• When the Green LED is "ON", it indicates Power ON and also that the input voltage and output voltage is normal; the AVR is working.
• When the Yellow LED is "ON" and flashes, it indicates that the regulator is in a delay status; the output will be delayed.
• When the Red LED is "ON" and flashes, it indicates the regulator is in a protection status.

f. Delay Operation

This model is designed with a delay feature to protect appliances with compressors which should not be switched on immediately after being switched off. The delay time is generally set from 6/180 seconds. Please select delay or undelay before switching on the AVR. When the delay time has elapsed, the delay LED will switch "OFF" and the display will indicate the AC output voltage.

g. Integrated Automatic Protection Circuit (IAPC)

This model is equipped with a specially designed INTEGRATED AUTOMATIC PROTECTION CIRCUIT. This circuitry is redesigned to automatically cut off the input voltage whenever the input voltage is above the input voltage range, rendering full and comprehensive protection to the regulator and connected appliances. When the input voltage returns to within low and normal ranges, the IAPC will automatically switch the regulator back "ON" and also restore power to all connected appliances.

h. Temperature Protection

This AVR is equipped with a unique Temperature Protection Circuit designed to protect the transformer, giving you longer and satisfactory use of the Regulator. If the internal temperature reaches the limit or above, the output power supply will cut "OFF" automatically. There is no number to be shown in the display. When the internal temperature returns to the normal range, output power will be restored. After the delay time, the display will indicate output voltage.

i. High Output Voltage Protection

This AVR is built in with a very specialized feature HIGH OUTPUT VOLTAGE PROTECTION CIRCUIT. This 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 power supply will cut "OFF" automatically and the display will show "H". At the same time, the Red LED blinks. Once the input city power returns to the normal range, the AVR will restore the output.

j. Low Output Voltage Protection

When the output voltage is below the normal range, the output will be cut "OFF" automatically and the display will show "L". At the same time, the Red LED blinks. Once the input city power returns to the normal range, the AVR will restore the output to the loads.

k. Short circuit protection

In case of a short circuit or overload, the power switch will trip off the input power supply automatically. Please check if the AVR is overloaded; if so, please remove some loads. Please check if the appliances are short circuit; if so, please disconnect the appliances.
