Mounting the rack
a) The rack is delivered in lengths of 1 meter. The two lengths with springs are to be mounted on the left and
right end.
No warranty if the rack is used without these springs!
b) Disengage the opener and close the gate manually and mark during closing the mounting height for the
rail on the gate (149 mm above the base plate of the opener).
c) Drill holes Ø 6,5 mm in the intervals as shown below. Tap M8 threads.
d) Screw the distance pieces into the gate.
e) Fix the first length of rack and ensure that the spring is fitted inside. Don’t tighten the screws until the
assembly is complete.
f) Push five plastic rack segments into the rail, hooked together as shown below. Push the segments into
the rail until they are against the spring. The fifth segment will protrude.
g) Hooked six segments of rack together and insert into the next length of rail so that they protrude at both
ends.
h) Hook the protruding end into the protruding end of the first length. Push this rail against the first rail.
j) Screw this length onto the distance pieces.
k) Connect the butt joint of the two lengths of rail with
the connecting piece.
l) Carry on in this way until only the length of rail with
the second spring remains.
m) The last segment of plastic rack must be cut off so that it fits flush against the spring.
n) Re-engage the opener (turn hexagonal key 180° clockwise).
o) Push the rack lightly onto the pinion and check that the teeth are fully engaged. Make any necessary
corrections. Tighten all screws.
p) Disengage the opener and push the gate until the next joint in the rack and carry on as under (o).
q) Carry on in this way until the rack has been checked in its entire length.
r) Remove the cardboard from under the opener.
s) Tighten the securing screws for the opener.
t) A test run of the gate to check the rack will be done during the setup of the controller.
Check that the rack is correctly mounted and that all screws are tight.
The emergency release must work at every position of the gate.
