Introduction
Thank you for choosing our DU.350V ratiomotor.
All items in the wide Benincà production range are the result of twenty-years' experience in the automatism sector and
of continuous research for new materials and advanced technologies.
We are, therefore, in the position to offer higly reliable products that due to their power, effectiveness and useful life, fully
satisfy the final user's requirements.
General information
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. General features
A completely built-in system that does not alter the appearance of gates.
Simple and reliable, it can be installed on any hinged gate of up to a max. 3.5 m per wing.
Movement is quiet and smooth thanks to a lever system that adjusts the speed depending on the different operation
phases.
The full oil bath motor units prevents water seepage and formation of condensate which might permanently damage
motor operation.
Electric locking is not required because the irreversible system ensures locking of the wings.
Installation is easy; once the box is embedded, the motor unit is fastened with stainless-steel nuts and bolts.
A special key is supplied to release it for manual manoeuvre.
The foundation boxes are in hot-galvanized sheet metal to guarantee longer life. They are available in 90° version DU.90
or 110° DU.110.
Device DU.180 offers 180° opening (for wing lengths not exceeding 2 m).
The same DU.180 can be used for the automation of special passages.
2. Mechanical stops (fig. 1)
The gate to automate must have an opening and closing mechanical stop as the DU.350V is not equipped with electro-
magnetic limit stops.
3. Foundation box laying
Dig as per instructions given in fig. 2 and make sure that on one of the four angles, where suitable holes have been made,
a water drainage and a cable terminal have been prearranged. (fig. 3)
Cement the box and check it is horizontal with the level.
4. Motoreducer fixing
4.1 Fix the motoreducer with the 4 stainless steel M10 hexagon nut (part of the supply) that are fitted onto the screws
projecting from the embedded box.
P.N. In the box there are 8 screws; use the ones that are suitable to the requirements as per instructions given in Fig.
5.
4.2 Weld the drive unit to the wing as per Fig. 6.
4.3 Place the wing into its seat after fitting the ball between the foundation box pivot and the drive unit.
4.4 Connect the drive unit with the motor flask through the connection lever and close the cover (Fig. 8)
4.5 Before tightening the M10 nuts check that the flasks rest in the area of the 4 screws; if not, shim where necessary
always taking into consideration that the ratio-motor has to lay flat (check through a level).
5. Connections (fig. 9)
N.B.: Connect the filter as near as possible to the motor and in any case before the point where the motor cable runs
near other cables or wires.
For connections to the electronic gear case, please refer to instructions relative to the electronic gear case itself.
6. 110° opening (fig. 10)
When positioning the boxes for 110° opening, Art. DU.110, calculate dimension X (between pivot and load bearing corner)
so that it permits the rotation also in consideration of the gate thickness Y.
7. 180° opening
Device DU.180 offers 180° opening and use the DU.110 box. This option is recommended for wing length up to 2 m; it
can also be used for longer lengths but in this case operation would not be smooth and regular.
CAUTION
All Benincá products are covered by insurance policy for any possible damages to objects and persons caused by con-
struction faults under condition that the entire system be marked CE and only Benincá parts be used.
