What to do if my MacroAir Technologies AirVolution-D 370 displays a Supply Voltage Low Fault?
If your MacroAir Technologies Fan is showing a Supply Voltage Low Fault, it means the controller has detected that the bus voltage is below the required threshold and has disabled the fan. To resolve this: 1. Turn the incoming power off for two minutes, then turn it back on. 2. Ensure the incoming power supply meets the fan’s specifications. 3. Check if there have been recent power outages or storms in your area. 4. Verify that the motor wiring is correct.
What to do if my MacroAir Technologies AirVolution-D 370 shows a Supply Voltage High Warning?
If you receive a Supply Voltage High Warning on your MacroAir Technologies Fan, it means the controller is detecting that the bus voltage is nearing the upper threshold. You can try the following steps to resolve this: 1. Turn off the incoming power for two minutes, then turn it back on. 2. Confirm that the power supply is within the fan’s specified limits. 3. Check for any voltage spikes using a power quality recorder. 4. Verify that the motor wiring is correct.
What to do if my MacroAir Technologies AirVolution-D 370 displays a Supply Voltage Low Warning?
If your MacroAir Technologies Fan displays a Supply Voltage Low Warning, it indicates that the controller is monitoring the bus voltage and it's close to falling below the minimum threshold. Here’s what you can do: 1. Turn off the incoming power to the fan for two minutes, and then turn it back on. 2. Ensure that the incoming power supply meets the fan’s specifications. 3. Consider whether there have been any recent power outages or storms in the area that could have affected the voltage. 4. Confirm that the motor wiring is correctly configured.
Why is my MacroAir Technologies AirVolution-D 370 showing a Motor Temperature High Fault?
If your MacroAir Technologies Fan is showing a Motor Temperature High Fault, here are some steps to take: 1. Ensure that the motor temperature is below 110C. 2. Check that the end caps are open and there are no blockages in the blades, especially if you have an AVD3 model. 3. For AVD3 models, verify that the quick link on the safety cable is not pulling the rubber boot closed. 4. Confirm that the ambient temperature is below 50C. 5. Consider starting the fan earlier in the day, before the ambient temperature rises too high.
What should I do if my MacroAir Technologies AirVolution-D 370 Fan displays an EEPROM Read Error?
If your MacroAir Technologies Fan displays an EEPROM Read Error, turn the incoming power off for two minutes, then turn it back on.
What should I do if my MacroAir Technologies AirVolution-D 370 Fan shows a Keep-Alive Timeout error?
If your MacroAir Technologies Fan displays a Keep-Alive Timeout error, follow these steps to troubleshoot: 1. Confirm whether the touchpad was unplugged or not. 2. Ensure that the CAT5 cable is under 100ft in length. 3. Verify that the CAT5 cable is from the factory and has not been modified. 4. Confirm that the CAT5 cable is shielded. 5. Make sure that repeaters are properly installed on the network. 6. Double-check all network splices. 7. Plug the touchpad directly into the board.
What to do if my MacroAir Technologies Fan has a Stalled Rotor?
If your MacroAir Technologies Fan has a Stalled Rotor, check the following: 1. Make sure that there are no obstructions blocking the blades. 2. Ensure that the blades can turn freely by hand.
What should I do if my MacroAir Technologies AirVolution-D 370 Fan shows a Phase Current Following Error?
If your MacroAir Technologies Fan is showing a Phase Current Following Error, here are some steps to take: 1. Turn the incoming power off for two minutes, then turn it back on. 2. Confirm that the power supply is within the fan’s specifications. 3. Make sure that the blade length is properly set. 4. If you have a Gen 2 370 model, confirm that the motor leads are stripped.
What should I do if my MacroAir Technologies Fan shows an Ambient Temperature High Warning?
If your MacroAir Technologies Fan is showing an Ambient Temperature High Warning, here’s what you can do: 1. Make sure that the ambient temperature is below 50C. 2. Try starting the fan earlier in the day before the ambient temperature rises.
