System issue: Fan_H Alarm
This alarm will be triggered if any of the fans fail to rotate.
Auatco three-phase inverters are equipped with external fans, typically situated on the rear underside of the inverter. Depending on the inverter model, there may also be an internal fan.
The inverter will activate the alarm whenever fan operation is required.
It’s important to note that this doesn’t necessarily indicate a malfunction in the fan; it could be obstructed by debris such as grass, bug nests, dirt, etc., preventing it from spinning.
In colder temperatures, the fans may occasionally seize due to ice accumulation. Applying spray lubricant to the fans can enhance their resistance to freezing.
1. Go to Advanced Settings
- Press Enter, then Up once to highlight Advanced Settings, and then press Enter
- Password is 0010, enter that by pressing Down, Down, Up, Down, and then Enter
2. Go to Fan Test
- Once you are in advanced settings press the Up button until Fan Test is highlighted and then press enter
- Press enter again when it asks if you are sure
3. Let the fan test run and inspect the external fans
- Give the inverter about three minutes to complete the full fan test
- As the test is running, watch the external fans to make sure they all spin
4. Deal with fans that are not spinning
- If one or more fans is/are not spinning, check the blades to see if there is debris.
- Try to spin the fan with your fingers. If the weather is cold, it could be ice buildup.
- If the fan spins with your fingers but not when the fan test is running then it could be a bad fan.
5. If you think that you may have a bad fan
- Remove the four screws holding the fan in place.
- Pull the fan out and then disconnect the power cable.
- Swap the fan with one of the other fans and then run the fan test again.
- If the fan that was not spinning before still does not spin after the swap then the fan is bad.
6. After you confirmed that you do have a bad fan
- Contact Autarco Support support@autarco.com to get a new fan shipped out.
- Replace the defective fan with the new fan once it arrives.
- Run the fan test one last time to ensure that all fans are now operational.
