INTRODUCTION INTRODUCTION Congratulations for choosing a BTSR product. With our KTF/100HPS yarn feeding devices, with or without the SMART KTF 2000 control unit, you got an innovative, unique solution able to offer you multiple advantages concerning quality of your production.
Chapter 2 – Technical Data and Installation gives the necessary instructions to install the devices with or without the KTF/PW4 power supply. Chapter 3 – KTF/100HPS Operation gives a detailed description of the necessary operations to setup and program the KTF devices according to the application needs.
1 second (i.e. the time needed to complete the data transfer). The KTF/100HPS is a space saving device (125 x 60 x 40 mm). This permits to install several devices on the same machine with limited encumbrances. The device has been designed bearing in mind not only the technological aspects, but also the ergonomic ones.
SMART KTF 2000 control terminal. (Mode 04 – BTSR Patent). ! Possibility to find the best application conditions of KTF/100HPS device: (No of coils to be wound around the roller, ideal programming values for parameters etc), thanks to the continuous visualization, in graphic form, of both average and peak values of yarn tension.
Advantages obtained by using the SMART KTF 2000 Terminal combined with KTF/100HPSs ! Using the SMART KTF 2000 terminal connected to KTF/100HPS devices you have the possibility to develop a wide range of functions which facilitate the practical use of the installed KTFs (immediate download and upload of data), as well as to display fundamental data such as, yarn consumed and yarn tension.

KTF/100HPS Operation This function is particularly useful when it is necessary to use a yarn feed operating tension (P1), different from machine stop tension (P2), MAIN TENSION EXIT TENSION which, in turn, is different from the yarn relaxation tension (P2).
OFFSET P3.1 This function is used to adjust the mechanical clamping position of KTF/100HPS device. It clears possible measurement errors due to the different clamping position of the KTF/100HPS on textile machine. The displayed indication is the actual value resulting from the clamping position of the KTF/100HPS.
Mode 02 - Function selection without INC/DEC commands, with or without KTF/PW4 power supply By selecting Mode 02, the KTF/100HPS will be able to work without INC/DEC commands and without using the KTF/PW4 power supply. In such condition the KTF will use the parameters programmed within P1 menu ( –...

Page 42
The typical characteristics of Mode 01 are the following: Reset of graduated tension synchronized through a defined sequence of INC/DEC (deactivation/activation/deactivation); “Error Tension” Alarm active only when KTF/100HPS operates with P1 tension. Graduations Reset The A and B pulses, must not necessarily have the same duration, however it is important that their duration is not less than 60 msec.
The typical characteristics of Mode 02 are the following: INC/DEC commands usable like for Mode 00; The KTF/100HPS generates the “Error Tension” Alarm when the tension goes out of the programmed tolerance band and automatically resets the alarm as soon as the tension returns within the programmed tolerance band.
Such solenoid valve activates an air blow that directs the yarn inside a recovery chamber The solenoid valve can be driven either by the textile machine, or directly by the KTF through the CHA and CHB output signals (see paragraph “Electrical Interface of KTF/100HPS Devices”, page 2.4). - 3-22 - KTF/100HPS...
RELAX TENSION P2.2 RELAX SPEED P2.3 When the KTF/100HPS device operates in Mode 04 (see P3 programming level), these parameters have no effect. ERROR RESET In Mode 04, the reset of error conditions due to set threshold levels exceeded, is automatically performed (likewise Modes 02 and 03), as soon as the tension value drops again within the programmed tolerance band.

If the fault is not included in this table, please contact your local BTSR reseller, giving a detailed description of the kind of fault and the conditions in which it occurred. In the case where the BTSR Technical Service intervention would be required, before calling it is suggested to take note of the code printed on the faulty device, as this information will make diagnoses for the BTSR technicians easier.
# If, using very thin or soft yarns, you experience frequent yarn breakage during machine stop and restart phases with KTF/100HPS running, prior to start the machine at the maximum speed, it is advisable to perform 2/3 revs at test (or jog) speed, in order to extend the yarn, so that possible yarn over-feedings in the machine stop phase will be eliminated.
