Any state

After the cause has been remedied, faults can generally be reset by opening and closing the guard. If the fault is still dis-

played afterward, use the reset function or briefly interrupt the power supply. Contact the manufacturer if the fault could

not be 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.
