FITTING THE RACK
1- Manually move the gate to the closed position;
2- unlock the gearmotor (see paragraph Unlocking Device);
3- arrange the rack (optional)[10 - 11 - 12];
4- place the first element of the rack on the pinion in such a way that it protrudes 50 mm from the gearmotor [9]
creating the space required for the limit switch bracket;
5- secure the element in the slot with a screw or spacer depending on the type of rack chosen [10 - 11 - 12]. It is
advisable to tighten the rack retaining screws at the top of the slot so that the gate can be raised and the necessary
clearance between the rack and pinion maintained should the gate lower;
6-continue fitting the rack, aligning the modules one after another; to properly secure the modules, use a piece of rack
of about 150 mm to allow for tooth timing [13]. Once the last module has been secured, cut off the protruding part
with a saw.
7- when all the modules have been fitted, manually carry out various gate opening and closing manoeuvres to check
that it slides smoothly without friction;
8- lower the operator and lock the gearmotor leaving a clearance of 2 mm between the pinion and the rack [14] to
ensure that the weight of the gate does not negatively affect the gearmotor shaft.
FITTING THE LIMIT SWITCHES [15]
u
1-insert the nuts in the hexagonal seats on the magnet holder
2- insert the grub screw and nut
least 1-1.5 mm;
3- insert the adjusting screw and nut
e
4- assemble the bracket
NOTE: at this stage, it is sufficient to assemble the unit to then position it on the rack without having to tighten the
screws.
5- Position the complete limit switches on the rack in the appropriate positions.
NOTE: the limit switch marked on the cover with the letter "O" must be secured in correspondence to the gate-open
position and the one marked "C" in the gate-closed position [18].
6- To fasten the limit switch, first tighten the two screws
depending on the type of rack and then act on the grub screws
WARNING: Do not overtighten the grub screws
7- Should the limit switch not yet be sufficiently integral with the rack, you can adjust it by unscrewing the screw
WARNING: Do not exceed in this adjustment since you may deform the bracket.
