Mechanical Installation - tau T-ONE Series Use And Maintenance Manual

• Ensure that the weight of the leaf is within the application limits as specified in paragraph 2.1 "Application limits"
• Ensure that there are no points of increased friction at any point of gate travel, both in opening and closing.
• Ensure that there is no risk of gate derailing or risks of exit from the tracks
• Check resistance of the mechanical overtravel stops, ensuring there are no deformations even if the gate impact is strong on stopping.
• Check that the leaf is balanced and therefore does not move if left stationary in any position.
• Make sure that the fixing zone is not subject to flooding. If necessary, mount the gearmotor raised from the ground.
• Ensure that the gearmotor fixing zone enables safe and easy manual movement and release.
• Ensure that the selected surfaces for installation of the various devices are solid, protected from the risk of impact and guarantee a stable fixture.
• Ensure that parts of the automation cannot come into contact with water or other liquids
• Never place T-ONE in the vicinity of flames or heat sources; in potentially explosive, particularly acid or saline atmospheres, this may damage T-ONE
and cause malfunctions or hazardous situations.
• If the gate leaf incorporates a pedestrian access door or if this door is positioned in the gate movement area, ensure that this does not prevent
normal gate travel; if necessary install a compatible interlock system
• Connect the control unit to an electric power line equipped with an earthing system.
• The mains power line must be protected by an adequate thermal magnetic and residual current circuit breaker device.

3.2. Mechanical installation

Site location:
• Choose a position similar to the outlined area in fig. 4 when fixing the unit directly to the ground (lay one or two conduits for routing electrical
wiring, 1 fig. 4) if in concrete, or as shown in fig. 5 when an excavation is required, fig. 5A (right-hand closure) or fig. 5B (left-hand closure).
Base preparation:
• Dig the foundations to a depth of at least 15 cm with sufficient width. Fit a protective sheath for routing the electric cables.
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 ap-
prox. 42 mm from the gate (fig. 6).
Fixing the foundation plate assembly (model 400CPOR):
• Assemble the foundation plate as shown in fig. 8.
• The foundation plate must be positioned as shown in fig. 8A (right-hand closure) or fig. 8B (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.
Alternatively, a height adjustable base plate (P-550CPMR or P-550CPMR1 - fig. 17) can be used. In this case the fixed ties must be welded to the
track and after locked with 4 expansion bold M12x120 (see fig. 18). The adjustable base plate is then secured as indicated in fig. 19.
In this way the gearmotor can be adapted to an already existing system; the measurements indicated in fig. 18 must be respected.
Fixing the gearmotor (on foundation plate assembly model 400CPO):
• Anchor the gearmotor using 4 screws M8x30 and relative washers, as shown in fig. 7.
• 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. 7 - optional) and 4 nuts M8 (2 fig. 7 - 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 per-
fect 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 / T-ONEXL):
• 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
