When DIA ashes 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, briey interrupt the power supply.
Contact the manufacturer if the fault display is not reset after restarting.
Important!
If you do not nd the displayed device status in the system status table, this indicates an internal device
fault. In this case, contact the manufacturer.
