Frequently Asked Questions - Alvis AVRL-5005TAL-CS01B nJoy

What is the difference between DELAY and UNDELAY modes?

In DELAY mode (3 minutes), the output is delayed after power-on to protect devices with motors or compressors from frequent switching. In UNDELAY mode (6 seconds), output starts quickly for general electronics.

What does the red LED mean?

The red LED indicates the unit is in protection mode, meaning the output has been cut off due to abnormal conditions such as over-voltage, under-voltage, over-temperature, or overload.

How do I reset the circuit breaker after an overload?

First, remove some loads to reduce the total power. Then press the circuit breaker button again to reset it. If it trips again, there may be a short circuit.

What should I do if the display shows 'E1' or 'E2'?

This indicates overload protection has activated. Turn off the AVR, disconnect some loads, wait a few minutes, then turn it on again. If the error persists, contact the dealer.

Can I connect a UPS to this AVR?

Yes, you can connect a UPS to the output receptacle of the AVR. This provides voltage regulation before the UPS, improving its performance.

What type of input power is required?

The unit requires a pure sine wave input with frequency between 45 Hz and 65 Hz. Do not connect to square wave or modified sine wave sources.

How do I install the Alvis 5000 model?

For Alvis 5000, you must hardwire the input and output cables. Connect the input phase, input neutral, and earth cables from the mains, and the output phase, output neutral, and earth cables to the load. Refer to Figure 1 in the manual.

What does the letter 'H' on the display mean?

'H' indicates over-voltage (high voltage) protection. The output has been cut off because the input voltage exceeded the normal range. It will restore automatically when voltage returns to normal.

What does the letter 'L' on the display mean?

'L' indicates under-voltage (low voltage) protection. The output has been cut off because the input voltage dropped below normal range. It will restore automatically when voltage returns to normal.

How do I clean and maintain the AVR?

Disconnect the unit from power before cleaning. Use a dry cloth to wipe the exterior. Do not use liquid cleaners or spray. Ensure vents are free of dust. No internal maintenance is required by the user.

Important Safety Warnings4

The unit is designed only for use within 45Hz to 65Hz (depending on the model) input frequency and pure sine wave environment. Any other input frequency or wave form will affect the voltage range and load capability.
Please DO NOT connect the unit to the environment with direct current or simulated sine wave.
To prevent the risk of fire or electric shock, install the device in a temperature and humidity controlled indoor area free of conductive contaminants. (See the specifications in the product's datasheet for the acceptable temperature and humidity range.)
Don't connect any appliances to AVR, which exceeds its rated power capacity.

Instalation and Initial Startup5

Step 1. Inspection

Remove the unit from the shipping package and inspect it for damage that might have occurred during transportation. Notify the carrier and place of purchase if any damage is found.

Step 2. Placement & Storage Conditions

Install the unit in a protected area that is free of excessive dust and has adequate air flow. Please place the unit away from other units at least 20cm to avoid interference. Do NOT block the top or side air vents on the unit. Do not use the unit in an environment where the ambient temperature or humidity is outside the limits listed in the specifications. Operate the unit in an environment free of excessive dust, mechanical vibration, inflammable gases and explosive or corrosive atmospheres.

Step 3. Connect the Loads

The AVR-protected receptacles will provide stable power to connected devices by boosting and bucking the input power. Therefore simply connect sensitive loads to AVR-protected receptacles in order to secure them.

3.1 Make sure all appliances are turned "OFF", and put the POWER SWITCH of AVR to "OFF" position.
3.2 For Alvis 1000 and 2000, plug the appliances into the OUTPUT SOCKET of the AVR
3.3 For Alvis 3000 and 5000 make wiring connection as shown in Figure 1.

Step 4. Turn On/Off the Unit

Turn on the unit by pressing the power switch to "ON" position. Then, all connected devices will be powered on.

6 Operation

6.1 Delay Operation

The "DELAY" means the output of the AVR will be delayed for a specific time, after switching on the AVR or the output is restored from a protecting status.

It will prevent the appliances from being damaged due to frequent switching on and off.

Undelay

Delay

The default delay time is 6 seconds (UNDELAY) or 3 minutes (DELAY). Press down the DELAY BUTTON to select the "DELAY", or press it up to select the "UNDELAY".

For the appliances with motors and compressors, like fans, refrigerators, cooler, freezers, air-conditioners, pumps, small motors, please select □ Delay.

6.2 Over Voltage (High Voltage) Protection

In case that input voltage is over the normal range, the output will be cut off automatically and a letter "H" will be shown in the display.

When input mains power returns to normal range, the AVR will restore the output automatically.

6.3 Under Voltage (Low Voltage) Protection

In case that input voltage is below the normal range, the output will be cut off automatically and a letter "L" will be shown in the display.

When input mains power returns to normal range, the AVR will restore the output automatically.

6.4 Over Temperature Protection

In case that the temperature of transformer windings is beyond the normal range, the output will be cut off automatically and letter "c" will be flashing in the display.

When temperature of transformer windings returns to normal range, the AVR will restore the output automatically.

6.5 Short Circuit Protection

In case a short circuit happens to the AVR or appliances, the AIR BREAKER or CIRCUIT BREAKER will trip off to cut off the input power supply.

Check if the appliances have been short circuited, if so, please remove them.

If the AVR is short circuited, do not use it! Please turn to the authorized dealer or service center.

6.6 Smart Overload Protection

Once it is overloaded, the AVR will give display warning to inform the user to reduce the connected appliances.

When load is >110%±8%: output will be cut off within 30s if overload is not removed

When load is >120%±8%: output will be cut off within 6s if overload is not removed

Once it's protected, the AVR will retry to restore output for 3 times, if overload is still not removed during this period, the AVR will stop retrying to restore output, at this time a letter "E1" or "E2" will be flashing in the display.

When letter "E1" or "E2" is flashing, even if the overload is removed, the output won't be restored. In this case, please conduct below steps:

(a) Put the "POWER SWITCH" to "OFF" position to disconnect mains power.
(b) Switch off all the connected appliances, and remove the exceeding load.
(c) Switch on AVR and then switch on the appliance.
