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.
A single factor or combination of factors (thermal expansion, climate, frequency of use, etc.) may result in the position the gate
stops in changing over the course of the day, both when opening and when closing. Consequently, we cannot guarantee that the
gate will always stop in the same position.

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-ONE3B, T-ONE6B, T-ONE8BR and T-ONE10B), and electric clutch (T-ONE5A, T-ONE8A and T-ONEX-
LA)
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-ONE3B, T-ONE6B, T-ONE8BR and T-ONE10B) and 1.5 mm² (T-ONE5A, T-
ONE8A and T-ONEXLA), 0.5 mm² for the control circuits.
For connections to the control cards consult the relative instruction booklets:
-
K120M for T-ONE3B;
-
K125M for T-ONE6B;
5.
12V BATTERY INSTALLATION (T-ONE6B, T-ONE8BR and T-ONE10B)
If a battery is to be fitted on the gearmotor to guarantee operation in the event of a power failure, remove the cover and insert it in the relative
seat (fig. 13); then connect the power cables to the tabs.
6.
MANUAL RELEASE
In the event of a power failure, raise the cover from the lock, insert the relative key and turn as shown in fig. 14.
Then, as shown in fig. 15, pull the lever outwards to enable manual movement of the gate.
DC versions feature a safety micro-switch in the release lever ("A", pic. 15). In case the gate operator stays released for more
than 5 seconds, the operator will perform a cycle at a slow speed to reset the operating parameters to the values originally
saved (see "Restoring automatic operation").
7.
LIMIT SWITCH (T-ONE5A / T-ONE8A / T-ONEXLA)
The series T-ONE (230 Vac) has been designed to operate with an electro-mechanical micro-switch type limiter.
The cables are connected as shown in fig. 16:
1= grey (common);
2= orange (F.C. close - NC contact);
As shown in fig. 16, when the gear rotates clockwise and the spring moves as shown, if gate travel does not stop, invert the position of the red
and orange wires on the terminal board of the control card.
8.
FINAL CHECKS AND START-UP
T-ONE must be connected to the power mains by skilled and qualified personnel, in possession of all requirements for full com-
pliance with all legal provisions, standards and regulations.
Immediately after powering up T-ONE, perform a number of simple checks:
1. Ensure that the leds on the control card are lit.
2. Ensure that the motor does not activate any gate movement and that the flashing light is off.
If this is not so, disconnect the control unit from the power supply immediately and check the electrical connections carefully.
Other useful information for troubleshooting can be found in chapter 7.6 "Troubleshooting".
