MECHANICAL INSTALLATION

Checking the opening (fig.1).

• Check the dimensions of the opening, and their correspondence to the overall dimensions of the door supplied, taking into consideration any necessary tolerances in the case of installation in an archway.
• Check that no existing structures obstruct the assembly of the door.
• Ensure the resting surfaces are level and, if necessary, adapt them using appropriate shims.
• Check the solidity of the opening: secure anchorage must be ensured by means of brackets or anchor plugs. In the case of insufficient or dubious solidity, it is necessary to create an adequate self-supporting metal structure.

Fitting the uprights (fig.2).

• Measure the overall dimensions of the crosspiece (LT).
• Mark the exact position of the uprights on the floor.
• Remove the covers of the uprights and fix the bases according to the marks using special M8 size plugs.
• Plumb the uprights and fix them at the indicated points (A) with external brackets or (B) for fixing from inside column. M8 size plugs.
• Check that the installation is perfectly perpendicular by measuring the diagonals.
  Do not drill holes in the right-hand upright near the counterweight sliding area (C).

Assembling the crosspiece

• Remove the M8 bolts preassembled on the ends of the crosspiece.
• Carefully lift the crosspiece using a forklift truck or other lifting equipment. Make sure that it cannot fall while being lifted and protect the door section from being damaged (fig.3).
• Place the crosspiece on the uprights, reinsert the fixing bolts and tighten them (fig.4).
  Fix the crosspiece onto the side plate.
• For doors with PL > 4000 fix the crosspiece on the centre (to avoid unsightly bending of the frame).

Assembling the counterweights

• Completely unroll the belt leaving 1 spare turn wound around the winding drum and passing the belt around the transmission pulley (fig.5).
• Fix the belt in place using the special plaque (fig.6). Adjust the length of the belt so that the threaded bar remains approximately 200 mm off the ground (when the door is wide open).
• Finely adjust the balance using the 4 lower counterweight elements.

Installing the photocells

• Connect the photocells as shown in (fig.16).

Assembling the emergency release lever

• The emergency release lever must be assembled on the structure itself or on the wall at a minimum height of 1.8 m off the ground (fig.8).
• If it is assembled on the structure, use the measurements indicated in (fig.9) and place the drive cable in the spaces and connect it to the gearmotor brake (fig.10).
• Check that the device is operating correctly; when the lever is operated, the door section should be free to rise.

Installation of the Safety Linear Encoder (SLE)

• The SLE must be fixed to the sliding guide of the flexible door on the left side as shown in (fig.11) and connected as shown at the paragraph 5.

Positioning the curtain 

• Close the upper part of the plastic guides (D) by pushing on the outer side (fig.12)
• Insert each tooth side edge (E) of the curtain in the relevant guide, if necessary to make easier the operation remove the higher screw (F).
• Roll down the curtain so the bottom edge is 0.5m beneath the curtain inlet slot (fig.13).

ELECTRICAL CONNECTIONS

Electrical panel

• Insert the cables with the pre-wired terminal boards in the housing (fig. 14) and connect them to the boards (as shown in chap. 5). Fit the cables in the conduit and connect the connectors on the motor (fig.15).
  Cabling connection on the board must be done with main power cut off, for at least 30 sec.

Electrical panel/motor/safety device connections
