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

“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:
Black = 100 %

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.

The PRIORITY STOP state has priority over all the other states.
Digital outputs
The digital outputs signal the alarms in normal work conditions (and if F.25 > 0 ), they operate the electro
valves if the Selematic management of the brake is active.
Alarm 0
Pin 15; Pin 16
Relay output that signals that the first alarm thresholds have been exceeded (F.26). A luminous/acoustic
signal or the digital input of any control device can be connected to the output (e.g. PLC).
Alarm 1
Pin 17; Pin18
Relay output that signals that the second alarm thresholds have been exceeded (F.27). A luminous/acoustic
signal or the digital input of any control device can be connected to the output (e.g. PLC).
EV.0
Pin 15; Pin 16
Relay output to connect to the electro valve to include or exclude SECT.2 of the brake.
EV.1
Pin 17; Pin18
Relay output to connect to the electro valve to include or exclude SECT.3 of the brake.
Analog input AIN0
Pin 20 ( + ); Pin 19 ( - )
The signal must be 4÷20mA, ΔI > 2,2mA.

Diameter reference
If F.30 = 1.
It accepts an analog reference proportional to the diameter. It can come from an ultrasound sensor (e.g.
US3), or from any sensor or controller that has a 4÷20mA signal.
Remote set point
If F.30 = 0.
It accepts an analog reference proportional to the maximum SETPOINT (100.0) desired for the material; a
potentiometer (manual setting) or the analog output of any control device can be connected to it (e.g. PLC).
Analog input AIN1
Pin 20 ( + ); Pin 19 ( - )
The signal must be 0÷10V, ΔV>1,1V.
Diameter reference
If F.30 = 0.
It accepts an analog reference proportional to the diameter. It can come from an ultrasound sensor (e.g.
US3), from the potentiometer of a feeler or from any sensor or controller that has a 0÷10Vdc signal.
Remote set point
If F.30 = 1.
It accepts an analog reference proportional to the maximum SETPOINT (100.0) desired for the material; a
potentiometer (manual setting) or the analog output of any control device can be connected to it (e.g. PLC).
If you use a potentiometer (manual setting) the potentiometer supply tension is provided by Pin 8 (9V).
Analog output proportional to the diameter
Pin 22 ( + ); Pin 21 ( - )
The output signal is 0÷10V.
Proportional to the diameter
It provides an analog reference which can be used to display on a remote display the reel diameter detected.
Analog output adjustment
Pin 24 ( + ); Pin 23 ( - )
Type of output signal:
if F.70 = 0 0÷10V
if F.70 = 1 4÷20mA
Brake or clutch control
It provides a command analog reference (torque adjustment) for a brake/clutch; the analog input of the
electro-pneumatic transducer (pneumatic brake) or, using the Re S.p.A. FP25 or TAURUS command board, a
magnetic powder brake, must be connected to it.

Detailed description of the programming functions
Function 1 – Braking in STOP
Use this function to set a percentage of the use of the brake/clutch or motor when the machine is stationary
(STOP state).
Press enter to access the function and the function value set is displayed.
Press up or down and set the desired percentage.
Press enter to confirm.
Function 2 – STOP braking variation percentage
Use this function to set the tension variation percentage with the machine stopped according to the reel
diameter. Example: if F.2 = 50 when the diameter is maximum the braking with the machine stopped will be
the one set in F.1, when the diameter will be minimum the braking with the machine stopped will be reduced
by 50%.
Press enter to access the function and the function value set is displayed.
Press up or down and set the desired percentage.
