desired height. Fix the motor by firmly tighten the 4 screws
V4 (M10x70) and related flat washers R and knurled washers
Z, as shown in the figure.
POSITIOnInG OF THe LIMIT SWITCH BRACKeTS
Manually open the gate and leave a clearance from 1 to
3cm according to the weight of the gate between the main
door and the mechanical stopper A. Fix the bracket to the
limit switch S by using the grains G, so that the limit switch
microswitch F is pressed. The same operation should be
repeated with gate in the closing phase.
N.B.: The limit switch bracket should be positioned so that
the gate can be stopped without hitting the mechanical
stopper.
HOW TO InSTALL THe MAGneTS
(BULL 5M.S - BULL 8M.S - BULL 8OM.S)
The magnets are housed in special supports (fig.8-"A").
These magnets are to be fitted to the limit switch brackets
or the rack and cause the triggering of sensors when they
approach them.
Fitting onto the limit switch brackets
The bases are complete with hooking tongue allowing the
fitting of the magnets to the limit switch bracket supplied
with the operator, as shown in Fig.8-B.
This type of fitting allows to rapidly adjust the position of
magnets. After calculating the correct distance, fix the
support in the correct position by means of a screw, so as
to avert the moving of the bracket.
Fitting onto the rack
As an alternative, the supports can be fitted directly to the
rack, by using the slots shown in Fig. 8-C. This fitting mode
does not allow for subsequent regulations. It is therefore
advised to make some trials with temporarily fitted supports
before carrying out the final fitting.
IMPORTAnT: The correct distance of the magnet
with respect to the sensor depends on the installation
characteristics. This space cannot be preset and must be
adjusted on a trial basis.
The distances regarding the triggering of the sensor (value
X) with respect to distance K of 3 and 35 mm, which are
shown in Fig. 8 are only indicative.
In any case, distance K must not exceed 35 mm as a
higher distance will not allow the triggering of the magnetic
sensor.
MAnUAL OPeRATIOn
Should a power failure or malfunction occurs, to manually
operate the gate proceed as follows:
- After inserting the customised key C, turn it anti-clock-
wise and pull the lever L.
- The gear motor is unlocked and the gate can be
moved by hand.
- To return to the normal operating mode, close the
lever L again and manually activate the gate until it is
geared.
WIRe DIAGRAM
For the wire connections of the system and to adjust the
operating modes, please refer to the Instruction Manual of
the control unit.
In particular, the anti-crash device (encoder) should be
adjusted according to regulations in force.

Please remember that the device should be earthed by
means of the appropriate terminal.
Fig.10 shows wiring for a standard installation. Before
proceeding to wiring, check that the type of cables used is
consistent with those required for accessories.
