HOW TO ADJUST THE GEAR MOTOR HEIGHT
As indicated in the previous paragraph, height is adjusted by
using grub screws K which are placed on the plate. Should
the gear motor height must be adjusted, proceed as follows:
- back-off nuts D
- back-off nuts W
- adjust the 4 grub screws K by using a 6mm hexagon key.
- once the correct height of the geared motor is obtained,
fix nuts W and K again.
Do not raise the plate for more than 20 mm in order not to
exercise excessive stress onto the foundation bolts (Fig.7).
HOW TO FIT THE RACK
Temporarily fit the rack by using clamps, for example. Check
that the system is perfectly flat, then fit the rack to the gate
with various welding points of by using adequate screws.
Keep to the tooth pitch P, even from the rack spaces. To this
purpose, it might be useful to match another piece of rack
(Fig. 8 - Detail C).
Lastly fix the rack with screws V, making sure that, once the
actuator is installed, around 2 mm backlash is left between
the rack and the drive wheel (see Fig. 9).
HOW TO POSITION THE LIMIT SWITCH BRACKETS
Manually open the gate, leaving 1 – 3 cm space, according
to the weight of the gate, between the gate/door and the
mechanical stopper A (Fig. 10).
Then fix the bracket of the limit switch S in order that the
micro-switch F of the limit switch is kept pressed.
After drilling two holes of ø 5.5mm, use the two screws G
supplied.
Repeat this operation with closed gate/door.
NOTE: The limit switch bracket should be positioned in order
to allow that the gate/door stops its movement without hitting
the mechanical stopper.
MANUAL OPERATION
In the event of power failure or faults, the gate can be
manually operated as follows (Fig.11):
- Open the protective cap from the lock, introduce the
customized key supplied and turn it by 90° anti-clockwise.
- Remove the lock group, introduce the hexagonal key
supplied, and loosen the screws anticlockwise until the
gate leaves are released.
- The gear motor is released and the gate can be manually
opened or closed.
- To reset the normal operation, introduce the hexagonal
key one again and turn firmly clockwise until it is locked.
With an automatic operation check that no slipping occurs
when the gate leaf is moving.
- Apply the lock group again, making sure that the anti-
rotation pin be introduced in the hole on the gear group.
- Turn the key clockwise, then remove it and close the
protection cap again.
CONNECTION TO GROUND (EARTH)
As regards the COMPULSORY earthing, a special Faston
4-pin connector fitted onto the central support (Fig. 12 –
CARTER-GND) is supplied. Ground connections of the upper
removable side and the lower side can be connected to this
Faston.
To allow an easy removal of the sides, they are not supplied
pre-cabled to the connector. The installer shall provide for
their connection, by using the already equipped with Faston
terminal.
As shown in Figure 12, mains power supply should be
connected to the mains filter (Fig. 12-FILTER), while for
grounding the special terminal should be in use (Fig. 12-GND).

As regards the wire connection of the automatic system and
the adjustment of the operating modes, see the instruction
manual of the control unit.
Before introducing the cables, check the type of cabling
required for the accessories actually used.
