in operation
- Disabled actuator within the actuating range
- Most recently taught-in actuator within the actuating range
- No actuator detected after 3min.

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 briey interrupt the power supply. Please contact the manufacturer if the fault
could not be 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, you should contact the manufacturer.
