11. Power failure
After power failure or disconnecting from mains the position of the wing/wings is unknown
to the controller. The controller first works in a starting mode. The wings are mowing
slowly. A pressure relief of electromagnetic bolt occurs before every movement. The wings
close one after the other. When stopping at the end position (closed), the controller
recognises this position. The controller continues in its regular mode.
Note:
Emergency mode is possible during the starting mode.
12. Fault diagnosis
