HOW TO FIT THE RACK
Place the D spacers (Fig. 8) and weld or fit them with screw
s onto the gate, keeping to overall dimensions shown in
Figure 2, taking also account the possible adjustment of the
foundation plate shown in Figure 7. Lastly, fix the rack.
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). To this purpose,
also use the slots on the rack.
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 repeatedly turn clockwise the system until
it reaches its limit switches.
- The gear motor is released and the gate can be manually
opened or closed.
- To reset the normal operation, introduce the hexagonal key
once again, and turn it repeatedly anti-clockwise, until it
stops.
- 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 –
GND) is supplied. Ground connections of the mains, 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 regards the ground connection of the power supply line
refer to instructions in the control unit.
WIRE DIAGRAM
Figure 13 shows the cables to the preset for the installation
of the gear motor and the main accessories.
As regards the wire connection of the automatic system and
the adjustment of the operating modes, see the instruction
manual of the control unit.
Namely, the calibration of the anti-crash device sensitivity
(encoder) should be carried out in compliance with
regulations in force.
Before introducing the cables, check the type of cabling
required for the accessories actually used.
