What to do if my TECO Inverter shows OH-C error?
If your TECO Inverter displays an OH-C error, you can try reducing the carrier frequency. If the issue persists, improve the ventilation conditions. Should this fail to resolve the error, the inverter may need replacement.
How to fix -OH- error on TECO L510S Inverter?
If your TECO Inverter is overheating and displaying an -OH- error, try improving the ventilation conditions around the unit. If the problem continues, it might be necessary to replace the inverter.
What to do if TECO L510S displays -LV- error?
If your TECO Inverter shows an -LV- error, here are some things to check: 1. Verify that the power voltage supplied to the inverter is correct. 2. Check for any failed resistors or fuses within the inverter. If these steps don't resolve the issue, further assistance may be needed.
How to solve HPErr error on TECO Inverter?
If you encounter a HPErr error on your TECO Inverter, check the inverter capacity setting (parameter 13-00) to ensure it matches the hardware voltage levels. Adjust the setting if necessary to align with the hardware requirements.
