General Information - Beninca BOB 21M Manual De Instrucciones

• Before installing the automatic system read the instructions hereunder carefully.
• It is strictly forbidden to use the product BOB 21M 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
- all hinges must have positive clearances and permit smooth and regular manual operations.
- when wings are closed their height have to fit together.
As the actuator is not supplied with electromagnetic limit switches, it is indispensable to provide mechanical
stops on closing and opening on the gate that is to be automated (fig.1)
If there are no mechanical stops present and it is not possible to provide them, adjustable mechanical stops
incorporated in the actuator may be used.
The mechanical stop is adjusted as follows (fig.3):
1 bring the wing into maximum opening/closing position
2 slacken the screw V (fig.3) just enough to be able to move the block B
3 position the block B in contact with the pin P.
4 for millimetre regulation, rotate the block B through 180°.
The standard travel of 270mm may be increased, if necessary, by removing one or both of the adjustable
mechanical stops. The removal of each stop increases the travel by about 30mm.
In this case it is indispensable to use the stops in fig. 1 and to allow an overtravel safety distance of at least
5/10mm, on both opening and closing.
Stabilise the height of the automatic system above ground level (it should be as central as possible with re-
spect 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. 3, 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.3A) 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.
1 remove the fixing nut of the cable clamp "G" from the bottom of the actuator.
2 insert the cable as indicated in Fig.5
3 block the cable by tightening the fixing nut "G".
4 for connection to the control unit, refer to fig.5 and to the control unit instructions.
It is obligatory to make the connection to earth using the special terminal (fig. 5 "GND").
