5.4.2. STEEL RACK TO BE SCREWED (F
Manually move the leaf to its opening
position.
Rest the first section of rack on the pin-
ion, positioning the spacer between the
rack and the edge of the gate. Using
a spirit level, check if the rack is horizontal
and mark the perforation point with a felt-
tipped pen.
Drill with a 6.5 mm diameter bit, and thread
with an M8 male element. Screw the bolt.
Manually move the gate, checking if the
rack is resting on the pinion and repeat the operations in point
Fit another rack element next to the previous one, using a piece of rack,
as shown in Fig. 14 ref.
, to synchronise the teeth of the two elements.
Move the gate by hand and perform the securing operations as for the first
element, carrying on like this until you have covered the gate completely.
Do not allow any superfluous sections of rack to project from the
gate.
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.15).
• Manually check if the gate correctly
reaches the travel-limit mechani-
cal stops and if there is any friction
during travel.
• Do not use grease or other lubricants
between rack and pinion.

6. START-UP
6.1. CONNECTION OF CONTROL BOARD
Before attempting any work on the board (connections, program-
ming, maintenance), always turn off power.
Observe points 10, 11, 12, 13 and 14 of the GENERAL SAFETY RULES.
Follow the instructions in Fig. 3, route the cables in the raceways and make
the electrical connections to the selected accessories.
Always separate power cables from control and safety cables (push-but-
ton, receiver, photocells, etc.). To prevent any electric noise whatever, use
separate sheaths.
6.1.1. EARTHING
Connect the earthing cable as shown in Fig. 16.
6.1.2. CONTROL UNIT
In the "C" version gearmotors, the electronic control unit is secured to an
adjustable support with a transparent cover.
The board programming push-buttons are located on the cover - this enables
you to program the board without having to remove the cover.
To connect the control unit correctly, follow the specific instructions.
6.2. POSITIONING THE TRAVEL-LIMIT ELEMENTS
To correctly position the travel-limit magnets, the control unit must
first be installed and correctly connected to all the command and
safety accessories.
The operator has a magnetic limit switch, which commands gate motion
to stop when the magnet, which is secured to the upper part of the rack,
activates the sensor. The magnets supplied with the operator are specifically
polarised and activate only one of the sensor's contacts: the closing or
opening contact. The magnet activating the open gate contact bears an
open padlock symbol, and, vice versa, the magnet activating the closed
gate contact bears the closed padlock symbol (see Fig. 17).
Procedure for correct positioning of the two travel-limit magnets:
To ensure the operator functions correctly, the magnet showing an open
padlock must be positioned on the left of the operator, looking at the au-
tomated system from the inside. Vice versa, the magnet showing a closed
padlock must be positioned on the right of the operator.
Assemble the two magnets as indicated in the attached sheet and in
fig. 17.
Set the operator to manual mode operation - as per paragraph 8 - and
power up the system.
Manually take the gate to opening position, leaving 4 cm from the travel
limit mechanical stop.
Slide the magnet nearest to the operator on the rack, in the direction of
the motor - see figure 18. As soon as the LED on the board, referring to
the travel limit stop, goes OFF, take the magnet forward by another 10
mm and fasten it with the appropriate screws (Fig. 18 ref.
