Technical Data - Beninca BOB21 Manual Del Usuario

Introduction
• Before installing the system, read the instruction
herein.
• It is mandatory not to use the BOB item for ap-
plications different from those indicated in the in-
structions herein.
• Supply the end user with instructions for using this
system.
• The end user should receive special instruction
manual.
• All Benincà items are covered by an insurance pol-
icy for damages and injuries caused by manufac-
ture faults. It is however required that the machine
bear the CE marking and original Benincà parts be
used.
General information
To ensure a good operation of these automatic devices,
the gate to be automated should meet the following
requirements:
- good strength and stiffness.
- hinges should have a minimum backlash and al-
low for smooth and regular manual operations.
- when closed, the gate leaves should correctly
overlap for their entire height.
As the actuator is not supplied with electromagnetic
limit switches, it is indispensable to provide mechani-
cal stops on closing and opening on the gate that is
to be automated (fig.1)
Fitting the automatic system
Stabilise the height of the automatic system above
ground level (it should be as central as possible with
respect to the gate and corresponding to a sturdy
cross piece).
Then weld the plate P respecting the distances in fig.
2.
When the gate is closing, weld the bracket S respecting
the distance in fig. 2, onto a cross piece of the gate or
another suitably robust element; bear in mind that in
this condition the actuator must not be completely at
the end of travel.
Remove the protective cover C unscrewing the screw
F, then fix the actuator to the plate P with the screw
T, the washer L and the nut D (fig. 3).
Lastly block the actuator on the plate S with the screw
V and the washer R.
The holes in the actuator (fig.2A) help you respect the
optimum installation distances.
The adjustable fixing brackets, available on request,
allow a wider possibility of adapting the actuator to the
different installation conditions, also avoiding cutting
and welding the brackets supplied.
How to adjust the mechanical stoppers
The actuator is provided with adjustable mechanical
stoppers in the opening and closing phases. The sys-
tem is adjusted by suitably positioning the "Open" and
"Close" mechanical locks, as shown hereunder (Fig.2):
1) Unlock the automatic system by using the special
release lever, as shown in the instructions for the
user (page 21-22).
2) Close the door/gate leaf.
3) Loosen screws V1 and move the "Close" lock until
it reaches the pivot P, then tighten screws V1.
4) Open the door/gate leaf.
5) Loosen screws V2 and move the "Open" lock until
it reaches the pivot P, then tighten screws V2.
6) Reset the automatic operating mode.
Connections
1) The special plate P (Fig. 5) allows for using a link
for sheath or cable gland PG11, or PG13,5. Once
the type of cable gland is applied to the plate, fix
the latter to the adaptor cover by means of screws
V.
2) It is mandatory to provide for ground by using
the special GND terminal.
WARNING
The insurance policy, which covers any damages or
injuries caused by manufacture faults, requires that
the installation comply with regulations in force and
Benincà original accessories be used.
