3.5 - Installation of gearmotor

WARNINGS

• Incorrect installation may cause serious physical injury to those wor-

king on or using the system.

• Before starting automation assembly, make the preliminary checks as 

described in paragraphs 3.1 and 3.2

.

Before proceeding with installation, position the door halfway along its travel 

and then anchor the gearmotor to the base (column). This ensures that the 

mechanical limit switches are automatically adjusted correctly (Paragraph 3.6).

01.

 Insert the lid on the release into the hole provided and anchor it in place 

with the screw and washer provided (

fig. 3

)

02.

 If the installation is not sufficiently easy, use the 2 dowels provided and fit 

them into the slots at the bottom of the column (

fig. 4

); insert the gearmotor 

in the column and align it with the slots provided (

fig. 5

);

03.

 Remove the dowels and anchor the gearmotor in place with the M8 screws 

provided (

fig. 6

). 

Important

 – You can adjust the height of the gearmotor 

within a range of 5 mm;

04.

 Insert the triangular pin in the release shaft seat (

fig. 7

). You can adjust the 

overhang of the pin by adapting it to column width. Then check by inserting 

the release wrench. Anchor it in place with the nut provided, being careful 

to close it on the flat surface of the pin.

05.

 At this point, if there is already a rack, adjust the mechanical limit switches 

as described in point 3.6. 

If the rack is to be installed, proceed as follows:

a)

 Manually position the door at least 50 cm away from the limit switch stop 

(during closing);

b)

 Position the rack on the pin and check that it is perfectly aligned and 

there are at least 1 to 2 mm of play between the pin and the rack;

c)

 Manually put the door in the closing position (complete) and check that 

the first bracket used to anchor the rack in place is aligned with the center 

of the pin.

3.6 - Adjusting the mechanical limit switches

01.

 Release the gearmotor with the key provided (refer to point 3.7);

02.

 Then manually perform a complete Opening and Closing manoeuvre to 

permit automatic regulation of the mechanical limit switches. 

Important

 – 

During this maneouvre, check that the rack runs in alignment with the pin, 

with a misalignment of maximum 5 mm, and that there is a play of 1÷2 mm 

between pin and rack along its entire length (

fig. 8

);

03.

 Lastly, manually position the door halfway along its travel and lock the 

gearmotor in place with the key provided (refer to point 3.7).

3.7 - Manually releasing and locking the gearmotor

The gearmotor is equipped with a mechanical blocking system to enable man-

ual opening and closing of the gate.
These manual operations should only be performed in the event of a power 

failure, malfunctions or during the installation procedures.

01.

 Slide the disk covering the lock (

fig. 9

);

02.

 Insert the key and turn it clockwise (90° - 

fig. 10

);

03.

 It is now possible to move the door into the desired position manually.
