3. MECHANICAL INSTALLATION

See the relevant drawings of the mechanical installation at page. 26 – 27 (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 supplied bearing in mind any
tolerances needed if installed within the doorway. 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.
• Remove the covers of the uprights and fix the bases 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.
Do not drill holes in the upright near the counterweight sliding area (C).

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-5C), 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. For Ditec Traffic C with a modular curtain: 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.9)
• 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 counterweights

• Lift the counterweight using appropriate lifting equipment (forklift truck).
• Unroll the belts and pass them around the transmission pulleys. Wind the belt around the upper pin and fix it using the
special plate. Place the counterweight approximately 200 mm away from the stroke top end. (fig.9)
• Finely adjust the balance using the 4 lower counterweight elements. (fig.9)
3.7 Assembling the emergency release lever (optional)
• The emergency release lever must be assembled at least 1.8 m off the ground (fig.10, 11).
• Place the drive cable in the spaces and connect it to the gearmotor brake (fig.12, 13).
• Check that the device is operating correctly; when the lever is operated, the curtain should be free to rise.
• For Ditec Traffic CM with twin motors, the release devices are connected by way of the device shown in "figure 14".

3.8 Installing the photocells

• Install the containers on the column (fig.15). For connections, follow the instructions in the photocell package.

3.9 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.16).
• Run the edge along the entire length of the curtain and place it in the exact centre of the curtain.
