Accessories - Multi yarn break sensor system
SYSTEM DESCRIPTION:
The Multi yarn break sensor system makes it possible to
use multiple weft sensors on the feeders.
The sensors will detect possible yarn breakage on the
feeder input side.
The central box (concentrator box) has connectors for
feeders (4 connectors) and external yarn break sensors
(8 connectors).
PARTS:
The system consists of one concentrator box, power
supply cable, extension cables and sensors.

INSTALLATION
Carefully follow instruction below for a secure
installation.
Picture on page 21 explains the numbers mentioned in
the instruction. Appendix 1 & 2 show where to connect
the sensors and feeder cables to the concentrator box.
A. Make sure that the loom main power has been
switched off.
B. Fixate the concentrator box (3) to the feeder stand.
Use the supplied screws (length M5x50).
C. Fixate the external yarn break sensors with tensioner*
(5) on the bobbin creel (one sensor per yarn).
D. Open the cover of the concentrator box and connect
the extension cable (2) between the external break
sensors and the concentrator box. One extension
cable per sensor must be used.
It is important that the extension cables are conneted
to the correct connector in the concentrator
box. Use appendix 1 & 2 as a guide.
* The tensioner is not indicated in the picture on next page
