Thank you for choosing our KEN3/KEN4 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 highly reliable products that due to their power, effectiveness and useful life, fully satisfy the
final user's requirements.
All our products are covered by warranty.
Possible injury to people or accidents caused by defects in construction are covered by a civil liability policy drawn up with one of
the major insurance companies.
The system has been studied to motorize sectional doors.
To be applied onto balancing doors, a special fitting arm is required (item AU.C25).
In any case, following conditions will have to be observed:
- the distance between the door highest point and the ceiling must be at least 40mm (fig. 1).
- it has to be possible to open and close the door by pulling and pushing horizontally its top edge (fig.1).
- manual moves must be smooth and regular.
a) Introduce the screws into the profile slot (Fig.3).
b) Link the guide profiles by means of the two plates "P" by using the screws M6x12 (Fig.4).
c) Introduce the plate P in the aluminium profile until the holes of the plate correspond to the holes of the base plate B (Fig.5).
d) Fasten the plate P to the base plate by using the three screws M6x14. Provide for large washers between the plate and the screws
(Fig.6).
e) Slightly tension the chain by tightening the nut D1 (Fig.7).
N.B.: An excessively high tension might cause serious damage to the system and renders it noisy.
f) Firmly tighten the nut D2 (Fig.7).
g) Place the fixing brackets to ceiling, preferably near the motor and in proxy to the guide profiles link point (Fig.8). For fastening, see
Fig.9.
h) To anchor the ceiling fixing brackets to the guide profile (Fig.9).
i) Anchor the bracket "S" to wall or ceiling by using rivets or screws and dowels. Anchor the profile to bracket S with the hexagonal
head screws M8x80 and the self-locking nut (Fig.10).
l) Connect the dragging rod A to the dragging slide by using the hexagonal head screw M6x20 and self-locking nut. Avoid blocking the
rod. Adjust the bracket S height so as to ensure that, when the door is closed, the rod A is almost vertically positioned (Fig.11).
Open the door by pressing the special key on the board. Remove the load of the spring M and turn the cam C until triggering of the
two micro switches F1 and F2. Repeat the closure operation (Fig.12).
Move the fast-on switch F to obtain one of the two speeds (Fig.13):
• 20V: 4,3m/1', is recommended for balancing doors;
• 30V: 6,5m/1' for sectional doors.
In sectional doors, the system can be released also from outside by using item AU.MS25 (Fig.14/15).
1 - Fit the bracket "S" to the pulling slide "P" (Fig. 14):
A. Remove the screw M6x25 which is pre-mounted on the slide and replace it with one of the two screws M6x35 supplied in the kit.
B. Insert the standard hexagonal nut D1 supplied in the kit in the appropriate seat instead of the selflocking nut D2 which must be
used to fit bracket "F".
C. Complete the fitting of the bracket by using the other screw M6x35 and the selflocking nut D3, which is supplied in the pulling
bracket blister. Do not excessively tighten this screw as it could impair the movement of the pulling bracket "T".
2 - Mount the release cable onto AU.MS25" (Fig.15):
A. Insert the metal cable in the slide, as indicated in Figure 15.
B. Fit the adjuster on the bracket and insert the sheath.
C. Fix the other end of the cable to the release device. The figure shows an example of connection to the garage door handle AU.MS.
N.B.: Any type of cord release device can be used under the condition that the release stroke is of at least 15 mm.
Overhead door with balanceweights (fig.16): these doors need the special arm art. AU.C25.
In order to assemble it make sure that:
• the arm is fixed to the top edge of the door.
• the arm is levelled.
The civil liability policy, which covers possible injuries to people or accidents caused by defects in construction, requires to use original
Benincà accessories.
