Detailed description of the application
The following is a functional block diagram of the T-two device application:
The T-two regulator uses an automatic tension control system for torque regulated winding/unwinding
systems fitted with load cells or dancer rolls. The torque, which is transferred to the reel via a brake
(pneumatic or electro-magnetic) or clutch, is regulated by the PID algorithm in order to maintain the
tension applied to the material (or the position of the dancer roll) constant at the setpoint. The setpoint is
set-up locally using function F.18 (if F.38 = OFF) or remotely (if F.38 = On), using a potentiometer or an
analogue signal from the PLC, for example.
When the dedicated digital input is activated, causing the regulator to switch from the STOP to the
AUTO state, the regulation begins to apply a torque value that may be either the value set-up using
function F.1 (if F.48 = OFF) or the last value that was applied in AUTO mode (if F.48 = On). If the
STOPAUTO state transition occurs after the instrument has been set to the ZERO state in order to
change the reel, the regulator will restart at the torque value set-up in F.1, irrespective of the F.48
setting; this also happens if the instrument is disconnected from its power supply.
The regulator monitors the tension (or the position of the dancer roll) continuously and if any of the
alarm limits are exceeded the corresponding digital outputs on the T-two unit are activated; this enables
external devices, such as the PLC, to detect any fault conditions.
T-two is equipped with an auxiliary analogue output that can be used to control an external display
device or, when using a dancer roll to regulate the tension, the transducer that regulates the air
pressure in the dancer roll piston; this pressure value may be set-up locally using function F.32 (if F.40
= OFF) or remotely (if F.40 = On), for example by converting the analogue signal from a potentiometer
of the PLC.

Remote control of the states by PLC
The T-two unit is equipped with four digital inputs that are used to control the state of the regulator.
For a detailed description of the operating logic used to activate these inputs (closure of a 24Vdc
contact) see the paragraph Remote control of states by PLC in the unit installation manual.
It is important to note that the EMERGENCY remote command is a “virtual” function only and does not
correspond to any of the physical inputs and is activated only if both the ACC and DEC remote contacts
are active, as illustrated in diagram 1 below.
By using the ACC (F.6) and DEC (F.11) state delays it is possible use a different set of parameters, for
a predetermined period, in order to optimise the way the system reacts to the during the start and stop
phase transients using nothing more than the AUTO/STOP remote command.

Detailed description of the regulator set-up and parameters
menu (P.1)
The functions preceded by this symbol are valid for applications with dancer rolls only.
The functions preceded by this symbol are valid for applications with load cells only.
Function 1 –Torque in STOP state (%)
You can use this function to set-up the percentage of torque applied to the reel when the machine is
stationary (STOP).
Press to access the function, the display indicates the corresponding value.
Press +/ –to set-up the desired torque value, expressed as a percentage.
Press to confirm.
Function 3 –“Proportional” regulator in AUTO state
This parameter, together with the integral and derivative parameters, acts on the regulation when the
machine is operating at the working speed (AUTO state). Increase the value of the proportional
parameter to increase the system response speed so that it reaches the setpoint value more rapidly. If
the speed is too high the system could become unstable, resulting in excessive tension (setpoint
exceeded) and harmful oscillations.
Press to access the function, the display indicates the corresponding value.
Press +/ –to set-up the desired value.
Press to confirm.
Function 4 –“Integral” regulator in AUTO state
This parameter, together with the proportional and derivative parameters, acts on the regulation when
the machine is operating at the working speed (AUTO state). Decrease the value of the integral
parameter to increase the speed at which the regulator corrects the error at the working speed, so that it
reaches the setpoint value more rapidly. If the integral parameter value is set too low the system could
become unstable, causing the tension to oscillate continuously around the setpoint value, without ever
reaching a stable state.
Press to access the function, the display indicates the corresponding value.
Press +/ –to set-up the desired value.
Press to confirm.
Function 5 –“Derivative” regulator in AUTO state
This parameter, together with the proportional and integral parameters, acts on the regulation when the
machine is operating at the working speed (AUTO state). Increase the value of the derivative parameter
to improve the capacity of the regulator to predict the error trend and compensate for sudden variations
in the tension; it is also capable of damping the undesired effects caused by a high proportional value. If
the derivative parameter value is set too high the system may become highly sensitive, reacting to even
the smallest variations at the input (interference) and resulting in harmful oscillations.
Press to access the function, the display indicates the corresponding value.
Press +/ –to set-up the desired value.
Press to confirm.

Function 41 –Remote DANCER ROLL AIR PRESSURE filter
When the dancer roll air pressure value is acquired remotely (F.40 = On), you can use this function to
set-up a suitable value for the dedicated digital filter, in order to obtain a stable signal that is free from
unwanted variations. The higher the filter setting, the more the signal is filtered.
Press to access the function, the display indicates the corresponding value.
Press +/ –to set-up the desired filter value.
Press to confirm.
Function 48 –Retain in STOP mode the last torque value used in AUTO mode
Normally, when the machine is stationary, the torque percentage set-up in F.1, with the contribution of
the parameters set-up in F.16 and F.17, is applied to the reel; however, this means that torque applied
when the machine is restarted is always the same and this can result in a marked deterioration in the
regulation during restarts as the diameter decreases. To overcome this problem you can enable this
function that can be used to retain the last torque value used in AUTO (which will continue to decrease
as the diameter diminishes) as the machine restart torque value.
Press to access the function, the display indicates the current state of this function.
Press +/ –to select OFF if you wish to use the parameter set-up in F.1 as the starting torque, or On if
you wish to retain the last value used in AUTO mode as the starting torque.
Press to confirm.
Function 97 –Entering the “Admin”password
In order to prevent the user from modifying the regulator settings and/or parameters, access to the
functions included in the T-two “regulator set-up and parameters menu” is restricted to the personnel
authorised when setting the unit up. Therefore, it is necessary to enter the pre-defined “Admin”
password in order to access these functions (using F.98).
Press to access the function, the display indicates the corresponding value.
