  • Page 6: Intended Use Of The Device

    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”...

  • Page 7: Taper Tension" Function

    -one ULS “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.
