3. MECHANICAL INSTALLATION
See the relevant drawings of the mechanical installation at page. 24 - 25 (central sheet to be removed).
3.1 Initial checks (fig.1)
• Check the size of the opening and that it corresponds to the measurements of the door. Check that obstacles do not prevent
installation.
• Make sure that the mounting surfaces are level and adjust them using suitably sized spacers if necessary.
• Check the consistency of the opening structure: it must be securely anchored with brackets or plugs. If consistency is poor
or uncertain, a suitable self-supporting metal structure must be provided.
3.2 Fixing the uprights (fig.2)
• Measure the overall dimensions of the crosspiece
(LT)
and mark the position of the uprights.
• Fix the bases of the uprights according to the marks, using M8 size plugs
(fig.4).
• Plumb the uprights and fix them at the indicated points
(A)
when using external brackets or
(B)
when fixing from inside
the column. M8 size plugs. Check the diagonals.
3.3 Assembling the crosspiece
• Remove the M8 bolts preassembled on the ends of the crosspiece.
• Lift the crosspiece using appropriate lifting equipment.
• Place the crosspiece on the uprights, reinsert the fixing bolts and tighten them
(fig.3).
• For doors with PL > 4000 we recommend fastening the crosspiece in the centre (to avoid unsightly bending of the frame).
3.4 Placing the crosspiece in position
• By referring to
(fig.5A-5B)
, place the belt transmission wheel according to the position of the curtain. The standard installation
is as shown in
(fig.5A).
• If the belt transmission wheel does not remain in position
“5A”
, remove the wheel by loosening the M8 fixing bolt and put
the belt transmission wheel back into the required position. After fixing the wheel, check that it turns smoothly. Repeat the
same procedure for each support.
3.5 Assembling the curtain
• Insert the curtain in the uprights and lift it. Make sure that the belt rings are positioned correctly.
• Using the M8 bolts supplied, fasten the curtain attachment sleeve to the crosspiece
(fig.6).
• Lower the curtain until it is completely unrolled. Adjust the length of the curtain by rolling it onto the hook-up tubing if
necessary.
• Unwind the curtain lifting belts and leave at least two belt turns on the winding drum
(fig.5).
• Insert the belts in the belt rings placed along the curtain
(fig.7).
• Fix the end parts of the belts using the brackets on the 1st tube
(fig.7).
• Fix the tubes using the plastic shells to prevent them sliding sideways
(fig.8).
The shells are already fixed on the 1st tube.
3.6 Assembling the gearmotor
for manual operation (if required), insert the device following the indications in
(fig.9)
for K22 and in
(fig.10)
for K26.
Connect the safety micro-contact as shown in the diagram and make sure it is working correctly: the micro-contact must
stop motor rotation when manual operation is activated.
• Insert the key
(d)
into the special slot
(e)
on the winding shaft
(fig.12).
•
Slide the gearmotor onto the shaft.
• Fix the gearmotor onto the head
(fig.12)
using the special fastening.
•
Insert the silent block into the special slot
(f)
on the support plate by placing the components as shown in
(fig.13). (g)
washer 13x24 -
(h)
silent block Ø 25 -
(i)
washer 14x36 -
(m)
screw 12x55
•
Fix the silent block with nut
(l).
3.7 Installing the photocells
• Install the container above the column. For installation and connections, follow the instructions in the photocell package
(fig.14).
3.8 Installing the safety edge
• Place the curtain at a height of approximately 1 m.
• Insert the safety edge into the lower pocket of the curtain,
(fig.
15
).
• Run the edge along the entire length of the curtain and place it in the exact centre of the curtain.
