1 Ref. No. TTD November, 000 HOW TO REPLACE ROTARY SWITCH WITH ABSOLUTE ENCODER (000.)

2 FOREWORD It has been informed you in TTI- and - that the production of Rotary switch, used for the D Series and TLFDII Series as Needle position detector for a long time, has been discontinued and that an has been applied instead as the Needle position detecting part for the machines, manufactured in October 000 or later. We have a certain amount of Rotary switches for the maintenance parts in stock, however, continuous part supply will not be available due to the discontinuation of the part production. Therefore, you are requested to replace Rotary switch with when you need to repair customerinstalled machines. This document describes the instructions how to mount and how to conduct wiring. We will be pleased if it is helpful to you for reference when you replace parts or repair machines. CONTENTS Page A. Applicable parts and necessary parts. Applicable models...

5 B. How to mount This document is not only focused on the adjusting procedure and instructions how to modify Needle position detector from Rotary switch to, but also illustrates the instructions how to adjust the currently mass-produced models, equipped with from the very beginning of shipment. This chapter regards the second needle as the reference needle position when mounting in order to facilitate the procedure to fix screws. If you find color change operation unstable or other inconvenience after mounting it, please shift the reference needle position to the needle position in the middle of Needle bar case (for example, the th or th needle for -needle models) and remake adjustment.. How to position change cam () Change the color manually to the second needle and turn OFF main power supply. () Remove the Front cover of Color change system. () Rotate the part A with a spanner etc. as illustrated below. Change cam also rotates and the part B moves to the right or left along the Spiral groove. Spiral groove has a linear section, where B does not move even when A rotates. Stop A at the position around the center of the linear section with the second needle selected. A Cam shaft B Slide boss [Note] Conduct alignment in the same way, irrespective of the type of Color change system. Spiral groove Change cam () Check whether the second needle and the center of needle hole align on the same line or not. Align the second needle correctly. Needle plate

6 () Check whether the detecting plate of -turn switch collar is positioned at the center of detecting part of -turn detector (Photo-interrupter). If the detecting plate is not correctly positioned, loosen Fixing screw of -turn switch collar and adjust the position. Detecting plate -turn switch collar Detecting part of -turn detector. How to change the position of Color change motor If the harness of Color change motor is positioned at the top right corner (when viewed from the machine right side), rotate only Color change motor only by 0 degrees without rotating Gear box. (excluding D Series,- needle models) Rotate by 0 degrees Color change motor. How to remove Rotary switch and to mount ) Loosen Rotary switch pin (the shaft to mount Rotary switch) or set screw of Knurled screw and remove Rotary switch. Then remove Rotary switch stay. Rotary switch pin set screw (MXL) Rotary switch set screw (MXL) For models up to needles Rotary switch stay Knurled screw For -needle models

7 () Mount Base stud to the position, where Rotary switch stay was positioned. () Mount Coupling to the shaft of with the measurements, illustrated below: Mount coupling Marking line Coupling 0 degrees Marking line About mm Fix set screws (MXL) in places near to Absolute encoder. Coupling () Mount Connecting pin with the following measurements. Note) This operation is only for customer-installed machines to be modified to specification. Connecting pin About mm Fix set screws (MXL) in places near to Connecting pin. Coupling () Mount Encoder base to. Encoder base Fix Truss head screws (MXL) in places.
