ENGLISH
Adjust the height of the gearmotor and the distance from the gate,
referring to dimensions in Fig. 10.
This operation is necessary to ensure the rack is correctly secured and
to enable any new adjustments.
Secure the gearmotor to the plate, tightening the nuts.
Prepare the operator for manual operation as described in paragraph
8.
5.4. Assembling the rack
5.4.1. S
TEEL RACK TO WELD
(F
IG
. 11)
Fit the three threaded pawls on the rack
element, positioning them at the bottom of
the slot. In this way, the slot play will enable
any future adjustments to be made.
Manually take the leaf into its closing po-
sition.
Lay the first section of rack level on the
pinion and weld the threaded pawl on the
gate as shown in Fig. 13.
Move the gate manually, checking if the
rack is resting on the pinion, and weld the second and third pawl.
Position another rack element end to end with the previous one, using
a section of rack (as shown in Fig. 14) to synchronise the teeth of the
two elements.
Move the gate manually and weld the three threaded pawls, thus
proceeding until the gate is fully covered.
5.4.2. S
TEEL RACK TO SCREW
(F
IG
. 12)
Manually take the leaf into its closing po-
sition.
Lay the first section of rack level on the
pinion and place the spacer between the
rack and the gate, positioning it at the
bottom of the slot.
Mark the drilling point on the gate. Drill a Ø
6,5 mm hole and thread with an M8 male
tap. Screw the bolt.
Move the gate manually, checking if the
rack is resting on the pinion, and repeat the operations at point 3.
Position another rack element end to end with the previous one, using
a section of rack (as shown in figure 14) to synchronise the teeth of the
two elements.
Move the gate manually and carry out the securing operations as for
the first element, thus proceeding until the gate is fully covered.

OTES ON RACK INSTALLATION
Make sure that, during the gate travel, all
the rack elements do not exit the pinion.
Do not, on any account, weld the rack
elements either to the spacers or to each
other.
When the rack has been installed, to en-
sure it meshes correctly with the pinion, it is
advisable to lower the gearmotor position
by about 1.5 mm (Fig.15).
Manually check if the gate correctly
reaches the mechanical limit stops main-
taining the pinion and rack coupled and
make sure there is no friction during gate
travel.
Do not use grease or other lubricants
between rack and pinion.
6. START-UP
6.1. Control board connection
Before attempting any work on the board (connections, programming,
maintenance), always turn off power.
Follow points 10, 11, 12, 13 and14 of the GENERAL SAFETY OBLIGATIONS.
Following the instructions in Fig. 3, route the cables through the raceways and
make the necessary electric connections to the selected accessories.
Always separate power cables from control and safety cables (push-but-
ton, receiver, photocells, etc.). To avoid any electric noise whatever, use
separate sheaths.
6.1.1. E
ARTHING
Connect the earth cables as shown in Fig.16 ref.A.
6.1.2. E
LECTRONIC CONTROL UNIT
In the gearmotors, the electronic control unit is fitted to an adjustable support
(Fig. 16 ref. 1) with transparent lid (Fig. 16 ref. 3). The board programming
push buttons (Fig. 16 ref. 4) have been located on the lid. This allow the
board to be programmed without removing the lid.
For correct connection of the control unit, follow indications the specific
instructions.
6.1.3. C
ONNECTION OF POWER CABLE
(
FOR
739 24V
ONLY
)
The 739 24V gearmotor houses a screw terminal with fuse-holder (Fig 17)
connected to the primary circuit of the toroidal transformer. The mains
power cable 230 / 115 V ~ must be connected to this terminal, respecting
what was specified in Fig. 17. If you have to replace the fuse, use a fuse
type T1.6A/250V - 5x20 for a 230V power supply and type T3.15A/250V - 5x20
for a 115V power supply.
