3) Manually move the leaf to its open position.
4) Lay the first element of the rack on the pinion, on the first
spacer (fig. 10).
5) Secure the rack element to the leaf with a clamp (fig. 10).
6) Manually slide the leaf toward the closing point until you
reach the rack's third spacer, and fix it with a weld spot.
7) Definitively weld the three spacers on the gate. Procedure
for correctly fixing the other rack elements required to reach
the closing position:
8) Bring near another rack element to the last fixed element,
using a piece of rack to synchronise the teeth with the two
elements (fig. 11).
9) Manually slide the leaf toward the closing point until you
reach the pinion with the third spacer of the element to be
secured (fig. 11).
NB.:
Make sure that all the rack elements work on the centre of
the pinion's teeth. Otherwise, adapt the gearmotor's position.
10) Weld the element's three spacers (fig. 10)
Attention:
a) Do not, on any account, weld the rack elements either to the
spacers or to each other.
b) Do not, on any account, use grease or other lubricants
between rack and pinion.
11) To obtain correct play between rack and pinion, lower the
gearmotor by 1.5 mm, using the nuts supporting the
foundation plate. When you have finished adjusting, correctly
tighten the operator securing nuts.
Attention: If the gate was recently built, check this play (fig.12)
a few months after installation.
12) Manually check if the gate is free to open completely and
if leaf movement is good and friction- free.
3.4. POSITIONING THE STROKE-LIMIT MAGNETS
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. 13).
Procedure for a correct positioning of the two stroke-limit
magnets:
1) Assemble the two magnets as shown in figure 13.
2) Set the operator to manual mode operation - see chapter 6
- and power up the system.
3) Manually take the gate to opening position, leaving about
40 mm from the opening mechanical stop.
4) Allow the magnet, with the padlock open, to slide on the
rack in opening direction - see figure 14. As soon as the LED on
the board, referring to the opening limit-switch, goes OFF,
take the magnet forward by another 10 mm and fasten it
provisionally with the appropriate screws.
5) Repeat the operations from point 3 for the closing magnet.
6) Re-lock the system (see paragraph 6).
Important: before sending a pulse, make sure that the gate
cannot be moved manually.
7) Command a complete gate cycle to check if the limit-
switches are operating correctly.
