9 Operating status
9.1 Status messages and status LED
The status message in the graphics display describes the current operating status of the
inverter. Each inverter status message belongs to one of the ve possible operating sta-
tuses. The status LED always displays one of these operating statuses through a variety
of colours. In addition to the status messages, the inverter can also display warnings.
Warnings result from device errors or external failures which, however, do not affect the
mains operation of the inverter. Losses of yield are possible, however.
Warnings have no relation to the operating status and are displayed on the graphics dis-
play alternately with the current status message.
The status messages of the “Failure”, “Error”, and “Blocked” operating statuses, as well
as the warnings, usually require certain measures to be taken, see 10 “Troubleshooting”;
page 100.
