Any state
When STATE/DIA flashes red inversely once, the fault display can generally be reset by opening and closing the guard after
remedying the cause. If the fault is still displayed afterward, as well as for all other fault displays, briefly interrupt the power
supply. Contact the manufacturer if the fault display is not reset after restarting.
Important!
If you do not find the displayed device status in the system status table, this indicates an internal device
fault. In this case, you should contact the manufacturer.
