INSTALLATION OF THE END STOP SLIDING PLATES
A - POSITIONING
ATTENTION!
For safety reasons
install the
leaf
mechanic end
stops for both
opening
and
closing
movements.
• Move manually the leaf along the rail up to 5cm from the closing position.
• Position the closing sliding plate over the tooth rack starting from the opening side of the leaf, and make it slide towards the
closing position until it operates the closing limit switch through the actuator spring: you'll hear a "click".
• Repeat for the opening position with the other sliding plate.
ATTENTION!
• To guarantee a correct limit switch operation, ensure a distance of 30mm (tolerance ±5mm)
between the rear side of the operator and the sliding plates. A distance greater than 35mm can
cause the leaf to block when reaching opening or closing positions. A distance smaller than
25mm can cause the actuator spring breakage.
• The sliding plates should be set taking into account inertia and temperature variations, so that
the leaf should never reach the mechanic end stops during opening and closing movements.
Otherwise THE RELEASE FLAP COULD GET BROKEN while attempting to release the operator
mechanism. Because of seasonal temperature differences, it is advised to control the actual leaf
stop positions both is summer and in winter.
B - FASTENING
• Once found the correct position, fasten the closing sliding
plate to the tooth rack using 2 supplied M6 grub screws.
• Repeat for the opening sliding plate.
• If necessary, the sliding plate can be shortened cutting a
piece and then bending part of the remaining plate.
DEFINITIVE OPERATOR FASTENING
A
• Tighten the nuts on the J-
bolts completely.
• Put the plastic band back in
place and then the operator
plastic cover. Fix it at the
sides with its 2 screws.
B
•
Lock the operator by
manually closing the release
flap and taking off the
release key from the lock.
• Move manually the leaf for a few centimetres in any direction until the pinion locks.
IN CASE OF POWER SUPPLY LOSS: MANUAL RELEASE OF THE OPERATOR
A
• Fit the release key into the lock in the front panel of the operator unit and give it half turn anti-
clockwise.
• Push the release flap strongly downwards until the release mechanism is triggered.
• The leaf can now manually be moved freely.
ATTENTION!
The leaf should not stop against the mechanical end stops, otherwise the
release flap could break when applying the force necessary to move it.
B
• To relock the operator, close the release flap and taking off the release key from the lock.
• Move manually the leaf for a few centimetres in any direction until the pinion locks.
