Fixing the foundation plate assembly (model 400CPO):
• On completion of excavations, prepare the foundation plate
assembly by bending the anchor elements in the plate on
the same section mounting the inserts (1, fig. 6) for fixing the
gearmotor by means of screws. Embed the anchor elements
in concrete while leaving the inserts exposed for gearmotor
fixture; the foundation plate assembly must be perfectly flat at
1 or 2 cm from ground level and at a distance of approx. 42 mm
from the gate (fig. 6).
Fixing the foundation plate assembly (model 400CPOR):
• Assemble the foundation plate as shown in fig. 7.
• The foundation plate must be positioned as shown in fig.7A
(right-hand closure) or fig.7B (left-hand closure) to guarantee
correct meshing of the pinion and rack.
• Make a foundation plinth as shown in fig. 5 and install the
foundation plate, envisaging one or more conduit sheaths for
routing the electric cables. Check perfect positioning of the
plate using a spirit level. Wait for the cement to set.
• Lay the electric cables for connection to the accessories and
electrical mains as shown in fig. 3.
To facilitate connections, leave an excess length of cables of
approx. 30 cm from the hole in the foundation plate.
Fixing the gearmotor (on foundation plate assembly model
400CPO):
• Anchor the gearmotor using 4 screws M8x30 and relative
washers, as shown in fig. 8.
• Pass all cables through the holes on the base of the foundation
plate assembly.
• If the rack is already present, insert the 4 stud bolts M8x30 (1
fig. 8 - optional) and 4 nuts M8 (2 fig. 8 - optional) to adjust the
pinion at the correct height, leaving 1÷2 mm of play from the
rack, checking perfect levelling of the gearmotor with a spirit
level.
Fixing the gearmotor (on foundation plate assembly model
400CPOR):
• Anchor the gearmotor to the foundation plate assembly as
shown in fig. 9, using 4 nuts M8 and 8 washers.
• Pass all cables through the holes on the base of the foundation
plate assembly.
• If the rack is already present, adjust nuts (1 fig. 9) to set the
pinion at the correct height, leaving 1÷2 mm of play from the
rack, checking perfect levelling of the gearmotor with a spirit
level.
Fixing the rack (model 400CN):
• Release the gearmotor as described in the paragraph "MANUAL
RELEASE".
• Open the leaf completely, position the first section of the rack
aligned with the edge of the gate and check that the start of the
rack corresponds to the start of the leaf as shown in figure 10.
Check that there is a clearance of 1÷2 mm between the pinion
and rack.
• After positioning the first section of the rack aligned with the
edge of the gate, mark the drilling point on the gate, drill a Ø 4
mm hole and insert the self-tapping screw Ø 6,3 mm.
• Manually move the gate, checking that the rack is positioned on
the pinion and repeat the operations described in the previous
point.
• Move another rack element up against the previous one, using
the dovetail connection to mesh the teeth of the two elements
as shown in fig. 10.
• Manually move the gate and proceed with the fixing operations
as per the first element, through to complete coverage of the
gate.
It is very important to observe the installation
measurements and distance between the gear teeth
and rack teeth as shown in figures 6 and 10.
Note: the rack must slide on the gear of the gearmotor
throughout the entire length of its tooth (fig. 6).
Fixing the rack (model 400CFZ12):
• Mount the three threaded pawls on the rack element (A fig.
11) positioning them on the upper section of the slot. This
will ensure clearance on the slot for future adjustments when
required.
• Manually move the leaf to the opening position.
• Position the first section of the rack aligned with the edge of the
gate, and weld the threaded pawl onto the gate as shown in fig.
11.
• Manually move the gate, checking that the rack is positioned
on the pinion and weld the second and third pawl.
• Move another rack element up against the previous one, using
a rack element to mesh the teeth of the two elements as shown
in fig. 11.
• Manually move the gate and weld the three threaded pawls
through to complete coverage of the gate.
It is very important to observe the installation
measurements and distance between the gear teeth
and rack teeth as shown in figures. 9 and 11.
Note: the rack must slide on the gear of the gearmotor
throughout the entire length of its tooth (fig. 9).
Fixing and adjusting the limit switch pads (T-ONE5 - T-ONE8):
• With the relative stud bolts, fix the "opening" and "closing" limit
switch brackets at the ends of the rack as shown in figure 10
and 11. Take into consideration that when the limit switches
trip, the leaf continues to move by a further 2÷3 cm; therefore
the limit switch brackets should be positioned with a suitable
margin on the mechanical stops.
It is also recommended to slightly lubricate the point
of contact of the limit switch pad with the spring, to
facilitate sliding and prevent compression of the latter.
Note: to ensure complete safety, mechanical stops
(floor-mounted end stops), if not already present, with
rubber caps MUST be fitted, as shown in fig. 3.
3.3_ Version with chain pinion: T-ONEC Series
The door can also be power-operated as shown in fig. 12. Pass the
chain as shown in fig.
Fig. 12 also shows the type of chain required (pitch 1/2" x 5/16").
3.4_ Adjustment of the electronic clutch (T-ONE5B),
and electric clutch (T-ONE5 - T-ONE8)
IMPORTANT: Ensure that the impact force measured at
the points as envisaged by the standard EN 12445 is
less than the value specified in standard EN 12453.
• All motors in the T-ONE series are equipped with a settable
encoder for obstacle detection during travel. The maximum
thrust torque can then be set by means of the relative
potentiometer on the card.
3.5_ Installation of various devices
To install the other devices envisaged, refer to the relevant
instructions. Check in figure 3 the devices that can be connected
to T-ONE.
4_ ELECTRICAL CONNECTIONS
Before proceeding, ensure that the gearmotor is not
connected to the electrical mains.
• To make the connections, remove the cover from the gearmotor,
route the power cables through the holes on the foundation
plate assembly (if used) and through the lower body of the
gearmotor, then prepare them for connection to the terminal
board of the control card housed in the electrical components
support.
• Use cables with a minimum section of 2.5 mm² for the power
circuits (T-ONE5B) and 1.5 mm² (T-ONE5 e T-ONE8), 0.5 mm²
for the control circuits.
For connections to the control cards consult the relative instruction
booklets:
- K125M for T-ONE5B;
- K580M for T-ONE5 and T-ONE8.
