6) FITTING OF THE RACK (FIG.6-7-8)
6.1) RACK IN NYLON (FIG.6)
Position the rack at a height of 96 mm from the centre line of the fixing slot provided on the base on which the foundation plate will be
fitted. At that height, drill a hole on the gate and provide for a M6 threading.
Keep to the P tooth pitch, even from a section of rack and another. To this purpose, it could be useful to join another section of rack
(Part. C)
6.2) RACK IN FE 12X30MM (FIG.7)
EN
Position the spacers D by welding them or fitting them with screws to the gate, at 129 mm height from the centre line of the fixing slot
provided on the base on which the foundation plate will be fitted. Fix the rack by following points 4.3 and 4.4.
Keep to the P tooth pitch, for all sections of the rack. To this purpose, it could be useful to connect another section of rack (Part. C)
Then fix the rack with V screws, taking care, once the actuator is installed, that 1-mm backlash is left between the rack and the tow wheel
(seei Fig.8). To this purpose, use the slots on the rack.
7) POSITIONING AND ANCHORING OF THE ACTUATOR (FIG.9-10)
Position the gear motor on the foundation plate with the gear centred with respect to the rack.
Release the automatic system and check that the gear be correctly positioned along the entire stroke of the rack. If required, adjust the
alignment by using the special slots.
Fix the gear motor to the base by firmly tightening the 4 nuts D and inserting the R.
Apply the two screw covers C.
If the rack is already installed in a position which is higher than the pinion, the plate can be raised (20 m maximum) by moving the nuts
and the washers under the plate, as shown in Fig.10.
If the connecting cables already present make it difficult to fix the standard plate, the optional plate BULL P3 (Fig. 11) can be used, thus
allowing to raise the actuator installation by about 34 mm and facilitating the passage of cables.
Apply the two screw covers C.

8) POSITIONING OF THE LIMIT SWITCH BRACKETS (FIG.12)
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 mecha-
nical 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.
9) MANUAL OPERATION (FIG.13-14-15)
Should a power failure or malfunction occurs, to manually operate the gate proceed as follows:
• After inserting the customised key C, turn it anti-clockwise (Fig.13) and pull the lever L (Fig.14).
• The gear motor is unlocked and the gate can be moved by hand (Fig.15).
• To return to the normal operating mode, close the lever L again and manually activate the gate until it is geared.
10)HOW TO INSTALL THE MAGNETS (MS5.S) (FIG.16-17)
The magnets are housed in special supports (fig.16-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.
10.1)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.16-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.
10.2)FITTING ONTO THE RACK
As an alternative, the supports can be fitted directly to the rack, by using the slots shown in Fig. 16-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. 17
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.
