7.5.3 Error Numbers 01xx to 13xx - Disturbance on the Utility Grid
After a grid failure, the inverter monitors the utility grid for a specific period before reconnecting. When the inverter
monitors the utility grid after a grid error, the grid monitoring time is complied with. Certain errors, such as grid errors,
cause the inverter to shut down. In this case, the instantaneous value TmsRmg indicates the time for which the inverter
monitors the utility grid before reconnecting. This grid monitoring time can be defined in parameter GdErrTm.
