Information about device recovery
- In European Union member states
The device falls within the electrical and electronic equipment category, which must be disposed of not
amongst undifferentiated urban waste, but through separate collection. Therefore, at the end of the
device’s lifetime, it must be disposed of in conformity with the European standards adopted in the
member state in which it was installed.
WEEE (Waste Electrical and Electronic Equipment) may be intended for individual, collective or mixed
collection and recovery systems at designated centres (for more information contact the relevant local
authorities) or may be returned to the distributor when a new item of equipment is purchased. This
eliminates or reduces potentially negative effects on the environment deriving from improper use of the
equipment or parts of it.
For correct waste management, the relevant authorities promote the reduction of final waste disposal by
means of re-use, recycling and other forms of recovery to obtain raw materials from waste.
In the event of illegal disposal of WEEE, offenders will be punished in accordance with the sanctions
established by the member state in which it was installed.
- In non-EU countries
Recovery and final disposal of the device must be carried out in conformity with the standards in force in
the country in which it was installed. It may be advisable to take into account the information provided
regarding European Union member states.
The device bears a clear, visible and indelible indication allowing identification of the
manufacturer and the separate collection symbol (symbol on side).
This symbol, showing a wheelie bin with a cross through it, unequivocally indicates that the
device was released after 13.08.2005 and that it must be subject to separate collection.

Intended use of the device
The T-one ULS tension adjustment system has been designed to be integrated, embedded, within an
industrial plant.
The instrument features a front panel to control the adjustment parameters and to program and calibrate the
instrument itself.
The T-one ULS automatic adjustment system is used to update the torque of a brake or clutch based on the
diameter value of the reel, by performing a servo diameter open loop adjustment. The “Taper tension”
function (described in the following sections) lets you set the progress of the torque in relation to the
diameter.
The T-one ULS regulator acquires an analogue signal called “diameter reference”, that can be supplied by an
ultrasound sensor (e.g. US3), from the potentiometer of a feeler roller or from any distance sensor (the
accepted signals are 0÷10Vdc or 4÷20mA), processes it and based on this and the setpoint set, it updates the
torque on the brake/clutch.
Adjustment with unwinder: When the diameter is at the maximum level, the output set on the brake has the
setpoint set, during the unwinding of the reel the torque decreases proportionally to the diameter based on
the “Taper tension” settings, until the minimum diameter is reached. If the reel in use has a larger range in
diameter and in weight, you can manage up till three different braking sections (appropriately configured)
through the “Selematic” function.
Adjustment with rewinder: When the diameter is at the minimum level, the output on the clutch has the
value processed proportionally to the diameter and/or based on the “Taper tension” settings, during the
rewinding of the reel the torque increases proportionally to the diameter based on the “Taper tension”
settings, until (at the maximum diameter) the setpoint set is reached
The device is not suitable to work outside, in corrosive, explosive or highly dusty environments.

T-one ULS
Rev. 06/18 3/26
“Taper tension” function
The “Taper tension” function is normally used to avoid that the material on the reel is too tensioned (or not
sufficiently tensioned) as the diameter increases, and vice versa. It allows to change the brake use
percentage automatically, according to the diameter of the reel, and it is normally used on the rewinders, but
in some cases, it is also useful on the unwinders.
Rewinders:
The use percentage of brake or clutch has
a value calculated according to the
diameter until the diameter is less than
the Taper start value set (F.11), then it
decreases (or increases) as the diameter
increases, until it reaches, at the Taper
end diameter (F.12), the set point value
decreased (or increased) by the Taper
percentage set (F.10).
Example:
if you set: F.10 = -20 (Taper percentage) there will be: OUT = OUT if diameter < 200
F.11 = 200 (Taper start diameter) OUT = OUT - 10% if diameter = 500
F.12 = 800 (Taper end diameter) OUT = OUT - 20% if diameter = 800
Unwinders:
The use percentage of brake or clutch
has a value calculated according to the
diameter until the diameter is more than
the Taper start value set (F.11), then it
decreases (or increases) as the diameter
decreases, until it reaches, at the Taper
end diameter (F.12), the set point value
decreased (or increased) by the Taper
percentage set (F.10).
Example
if you set: F.10 = -20 (Taper percentage) there will be: OUT = OUT if diameter > 800
F.11 = 800 (Taper start diameter) OUT = OUT - 10% if diameter = 500
F.12 = 2

“Selematic” function
When working reels with high diameter and weight ranges, in order to maintain the same material tension,
the torque required from the brake when the reel has the maximum diameter is much higher than the
torque requested from the brake when the reel has the minimum diameter. Therefore, the brake must size
itself dynamically to adjust itself to the instantaneous torque requested, rendering the adjustment more
sensitive even when low torque levels are required from the brake.
The “Selematic” function manages, through two electro valves, the activation of three different braking
sections (section 1 is always active) whose torque percentages are known. In this way it sizes the brake
according to the instantaneous torque requirements.
The figure shows the pneumatic connection diagram of the three braking sections to the 2 electro valves and
to the transducer.
How to assign the calipers to the braking sections
SECT.1 Calipers that develop the smallest torque of the brake must be connected in section 1 (in the
example a caliper at 16%).
SECT.2 Calipers that develop a higher torque than the calipers in SECT.1 must be connected in section 2 (in
the example a caliper at 40%).
SECT.2 max (maximum value that can be assigned to section 2) = SECT.1 x 4 (in the example 64%)
SECT.3 Calipers that develop the highest torque must be connected in section 3 (in the example a caliper
at 100% plus a caliper at 40%).
SECT.3 max (maximum value that can be assigned to section 3) = (SECT.1+SECT.2) x 4 (in the
example 224%)
Note: All the examples refer to the maximum configuration, that is three braking sections.
However, only two braking sections can be set (SECT.1 and SECT.2) as long as the assignment criteria set out
above are complied with, and you set SECT.3 = 0, as it is absent and unusable.
RE calipers torque percentages
The torque percentage developed by each
caliper is shown by the colour found on the
actual caliper:

How to set the “Selematic” work mode
Perform these settings by following the order set out.
1. Enter in function F.50 the calipers percentages total in SECT.1 (in the example 16%)
2. Enter in function F.51 the calipers percentages total in SECT.2 (in the example 40%)
3. Enter in function F.52 the calipers percentages total in SECT.3 (in the example 140%)
Pneumatic and electrical connection of the electro valves
The pneumatic and electrical connection is shown in the figure below.
For the correct operation of the system, follow the pneumatic connection of the electro valve EV.0 to the
SECT.2, and the electro valve EV.1 to the SECT.3 as shown in the previous page. The air path between the
electro valves and the brake caliper must be as short as possible.

Instrument functioning
General information
The front panel features a seven-segments led display with four numbers and two bar graphs displays to
display all the adjustment parameters. The keypad allows access to the device programming and calibration.
The state led provides information on the instrument functioning state.
Display
Outside the programming environment, the display shows the diameter, detected by the “diameter
reference” input. Use the set key (see § Keypad on the next page) to display the set percentage of
brake/clutch use (set point).
In programming, use the enter key, to display the programming functions or the values of the associated
parameters.
Bar graphs display
The front panel features two bar graphs displays:
Display IN: visualizes the percentage, in relation to the full scale, of the diameter detected.
Display OUT: visualizes the use percentage of the brake/clutch of the signal on the adjusted output.
