Beninca RI.20T Betriebsanleitung Und Ersatzteilliste Seite 8

Thank you for choosing our RI.20T ratiomotors.
All items in our wide 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.
All our products are manufactured to the standard UNI 8612 and 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.
For an efficient operation of the sliding automatic mechanism, the gate must have the following features:
• The guide rail and its wheels must be suitable in size and mantained to prevent gate from excessive sliding
friction.
• When running, gate must not rock excessively.
• Opening and closing stroke must be regulated by a mechanical limit stop (to safety standard in force).
Automation for industrial sliding gates.
Sturdy and reliable unit designed and built for continuous service. Self-ventilated motor guarantees an unlimited
number of manoeuvres.
The motor has an electrobrake for limiting inertia and more immediate travel-end intervention.
The RI.20T consists of a painted aluminium unit containing the reduction parts, which are realized in high-grade
materials and totally immersed in oil. The irreversible geared motor ensures perfect gate closing without the
need of electric locking. The casing is in painted sheet metal with an ABS top.
A personalized key release enables manual gate operation in the event of power failure.
The RI.20T comes complete with travel-end and mechanical clutch; it is available in version 400 V.
The control panel is not incorporated.
Secure the foundation slab to the ground with no. 4 steel T pressure inserts to dimensions given in fig. 1 (it's
important the slab is securely fastened to the ground).
N.b. Go through holes F with a sheath suitable to the actuator feed cables.
Fe 12x30 mm rack (fig. 2)
Weld or screw the spacer pins D onto the gate at 144¸145 mm above the base of the foundation actuator slab
and maintain the same pitch as the rack drilling.
Now secure the rack and refer to points 4.1 and 4.2 before proceeding.
4.1 Keep the pitch of teeth between the two parts of the rack; the joining with another piece of rack would
make it easier to achieve (see fig. 2)
4.2 Secure the rack with the screws V making sure, once the actuator has been installed, that between
rack and the drive gear there is always approx. 1 mm clearance (see fig. 3); to get this clearance use
the slots on the rack.
Open manually the gate and leave approximately of 1¸3 cm, depending on gate weight, between gate and
positive mechanical stop A; tighten the limit stop flask S with the grains G to press the limit sto micro. Repeat
the sequence with closing gate.
To operate the gate manually, use the release as follows (see fig. 5):
• once inserted the personalized key C, turn it anticlockwise and pull the lever L.
• to reset the standard operation running, close the lever L and operate the gate manually, until
engagement.
