After the cause has been remedied, faults can generally be reset by opening and closing the safety guard. If the fault is
still displayed afterward, briefly interrupt the power supply. Please 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.
