Adjusting the Limit Blocks
Installation
These adjustments must be made before the programming
of the forces and the running-length.
Starting the programming procedure without correctly ad-
justed blocks may lead to damages on the garage door and
the operator!
Vorgehensweise:
1� The operator is mounted and the door-arm is xed to the gara-
ge-door� The trolley is locked to the chain and stands somewhere
between the two blocks� If, however, trolley and chain need to be
moved you may do this using the TEST/RUN button�
2� Release the trolley (Pic� 1) and manually close the garage door�
3� The block for the closing direction is now right in front of the
trolley (Pic� 2)� If not, the block must be moved until it touches the
trolley�
4� Tighten the blocks‘ screw to keep it in place� Take care not to
tighten it too strongly - the c-rail should not be bended�
5� Now the garage door needs to be opened manually� The trolley
will lock into the chain - you have to release it once again to fully
open the garage door� (Pic� 1)�
6� The block for the opening direction is now right in front of the
trolley (Pic� 3)� If not, the block must be moved until it touches the
trolley�
7� Tighten the blocks‘ screw to keep it in place� Take care not to
tighten it too strongly - the c-rail should not be bended�
