• Before installing the automatic system read the instructions hereunder carefully.
• It is strictly forbidden to use the product DU.IT24NV for applications other than indicated in this instruction
handbook.
• Show the user how to use the automation system.
• Give the user the part of the leaflet which contains the instructions for users.
• All Benincá products are covered by an insurance policy for any possible damages to objects and persons
caused by construction faults, under condition that the entire system be marked CE and only Benincá parts
be used.
For an efficient operation of these automatisms, the gate must have the following features:
- good stoutness and stiffness
- every wing must have one only hinge (if necessary, eliminate the others).
- all hinges must have positive clearances and permit smooth and regular manual operations.
- when wings are closed their height have to fit together.
1 Assemble the cam "B" as per Fig. 2 and firmly tighten the screw V (tightening torque 45 Nm max).
2 Fit the geared motor group to the casing with 4 of the 6 nuts supplied on the casing, according to the type
of assembly (see Fig. 3) and with the self-tapping screws supplied.
N.B.: Before tightening the fixing screws of the geared motor check that there is no clearance between the
4 screws and the reduction gear surface. In the negative, provide shim as required.
3 Pre-assemble the manual release to the gate supporting iron bar, as shown in Fig. 4.
4 Weld the drive unit to the gate as shown in Fig. 5.
5 Position the gate wing in the special niche, making sure that the ball is positioned between the pivot of
the foundation casing and the drive unit. Then link the drive unit to the motor connecting rod through the
special link bar (Fig. 6).
Standard assembly (ref. fig. 3-7).
- Adjust screw V so that, when the gate leaf leans against the mechanical stop, about 1÷2 mm space is
left.
- The opening limit switch is fixed and averts that the gates overcomes 105°. For smaller openings use a
mechanical stop on the ground or the electromechanical group DU.FCN.
Inside assembly (ref. fig. 3-8).
- The closing limit switch is composed of either the mechanical stop on the ground or the electro-mechani-
cal group DU.FCN.
- For the opening limit switch, regulate the screw V (95° max.). For greater openings use the group
DU.IT180N.
For connections to the electronic gear case, please refer to instructions relative to the electronic gear case
itself.
