PRELIMINARY WARNINGS
Check that the gate structure is in conformity with the regulations in force and that leaf movement is linear without
friction.
Preliminary checks:
check that the gate structure is sufficiently robust. In any case, check that the weight and dimensions of the gate
fall within the limits of use of the operator;
check that the leaf can be moved manually without force (points of greatest friction) for the entire travel of the gate
during both opening and closing;

Ÿ
Check that the area where the gearmotor will be fitted is not exposed to flooding. If so, install the gearmotor in a
position raised from the ground;
if the gate is not a new installation, check the state of wear of all the components, repair or replace the defective or
worn parts and perform any other operations necessary.
Use mechanical limits to handle leaf travel excess situations.
The reliability and safety of the automated device is directly dependent on the condition of the gate structure.
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.
1- Make the hole for the foundation plate respecting the dimensions
[2]
and arrange the plate according to the closing
direction of the gate
[4]
. The hole depth must be at least equal to the length of the cramp-irons
[5]
.
2- Fit the flexible hoses through which the electric cables will run so that they lead out of the plate
[4]
and protrude
from the hole by about 30-40 mm
[5]
.
3- Make sure that the plate is level
[5]
and start filling the hole with concrete.
4- Wait for the concrete to dry.
5-Run the electric cables (for connection of the accessories and electrical power supply) through the flexible hoses.
To make it easier to make the electrical connections to the control unit, it is advisable to keep a cable length of 400 mm
from the foundation plate hole
[5]
.
1- Remove the gearmotor casing by undoing the screws under the side caps
[6]
.
2- Remove the fastening nuts from the plate pins, position the gearmotor on the foundation plate sliding the pins
into the slots on the casing
[7]
. Make sure that the pinion faces the gate.
3- Make the necessary adjustments to level the gearmotor, raising or lowering it by turning the adjusting screws
A[8]
. At first hold the gearmotor raised by 2-4 mm and then lower it after having secured the rack
[8]
.
4- Fit the 4 washers and tighten the 4 nuts to secure the gearmotor parallel to the gate (remember to hold the
gearmotor raised by 2-4 mm)
[8]
.
5- It is recommended to maintain the distances
[8 - 14 - 17]
.
EMBEDDING THE PLATE
INSTALLING THE GEARMOTOR
FITTING THE RACK
FITTING THE LIMIT SWITCHES [15]
1-insert the nuts
u
in the hexagonal seats on the magnet holder
p
;
2- insert the grub screw and nut
q
in the magnet holder
p
making sure that it protrudes towards the rack
w
by at
least 1-1.5 mm;
3- insert the adjusting screw and nut
y
in the hexagonal seat of the magnet holder
p
;
4- assemble the bracket
e
using the screws provided
r
and insert the grub screws
t
.
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
r
, then act on the screw
y
to adjust the clamp distance
depending on the type of rack and then act on the grub screws
t
to securely lock the bracket to the rack.
WARNING:
Do not overtighten the grub screws
t
so as not to deform the bracket.
7- Should the limit switch not yet be sufficiently integral with the rack, you can adjust it by unscrewing the screw
y
.
WARNING:
Do not exceed in this adjustment since you may deform the bracket.
