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.
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 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.
MANUAL OPERATION
FIG.13
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.
