INSTALLING THE ELECTRIC LOCK
As the gearmotor allows the gate to be moved manually when
the motor is not operating, an electric lock must be installed to
ensure locking during closure.
The lock must be installed vertically on the upper guide upright,
if gate height permits, so that release is possible both from inside
and outside (fig. 18).

Install as follows:
•
Check if the upper guide upright is of sufficient size for
vertically securing the electric lock. If it is not, provide a
sturdy support bracket.
•
Make sure that the free space between the lower edge of
the guide upright and the upper edge of the gate is
sufficient to fit the counter-strike and enable correct
operation of the bolt (see fig. 19).

N.B.: The indicated measurements strictly refer to lock FAAC
V 75 code 712654 and to counter-strike FAAC code 720329.

•
Secure the electric lock vertically on the guide upright (or on
the support bracket).
•
Move the gate to its closing position (at about 2 cm from the
mechanical travel stop) and provisionally secure the counter-
strike. Secure it definitively only after you have tested the
automated system, checked the action of the closing limit switch,
and adjusted braking power.

Notes on installing the rack
•
Make sure that, during gate travel, all the rack elements
do not come out of the pinion.
•
Do not, on any account, weld the rack elements either
to the spacers or to each other.
•
After you have finished installing the rack, to ensure
correct meshing with the pinion, we advise you to lower the
position of the gearmotor by about 1.5
mm (Fig. 17).
•
Manually check if the gate
correctly reaches the mechanical travel
stops and if there is any friction during
travel.
•
Do not use grease or other
lubricants between rack and pinion.
4.4.2. STEEL RACK TO BE SCREWED (Fig. 16)
1)
Manually move the leaf to its closed position.
2)
Lay the first piece of rack level
on the pinion. Then place the spacer
between rack and gate, positioning
it on the upper part of the slot.
3)
Mark the drilling point on the
gate. Drill Ø 6.5 mm and thread with
a Ø 8 mm tap. Screw the bolt.
4)
Manually move the gate,
checking if the rack is resting on the
pinion and repeat the operations in
point 3.
5)
Fit another rack element next
to the previous one, using a piece of rack, as shown in Fig. 16, to
synchronise the teeth of the two elements.
6)
Manually move the gate and perform the securing
operations as for the first element, carrying on like this until you
have fully covered the gate.
