Troubleshooting

Error Messages

An Error is caused by a critical fault. In most cases when this occurs, the unit will shut down. The MATE3 system display will show an Event and a specific Error message. This screen is viewed using the MATE3 Home screen’s soft keys. (See the MATE3 manual for more instructions.) One or more messages will display Y (yes). If a message says N (no), it is not the cause of the error.

NOTE: The Radian series has no external indicators and requires a system display to identify an Error.

It is possible to clear an error by resetting the inverter. The inverter must be turned off, and then on, to reset it. Other possible steps are shown below (although it is still necessary to reset the inverter).
