8. Initial operation
Caution!
The automatic cut-out must be
correctly programmed for the CLOSE
and OPEN directions to prevent damage
to persons or property.
The operator system determines the maximum required
driving power during the first two runs after setting
the end positions of the door.
• Operate the operator system (with the door coupled)
to drive the door once from the CLOSED position to
the OPEN position and back to the CLOSED position
without interruption.
During this learning run, the operator system
determines the maximum push and pull forces and the
reserve power required to move the door.
