Broken tool detection control unit 28700

ELTEX control unit 28700 for ELTEX logic current weft sensors General description The 28700 electronic board is designed to fit in the control box of a Dornier “DU” type weaving machine. It is used when an analogue weft sensor, for example 2010-2, is replaced by a weft sensor with logic current output (for example E2070 type). The 28700 board can replace all boards with part numbers 25700, 25710 and 26700. Advantages When an old board and analogue weft sensor are replaced with 28700 board and E2070 weft sensor, the following advantages will be attained: • ANTI-function: This weft stop motion can detect if too many yarns are inserted simultaneously by mistake. • The E2070 weft sensor can easily be set up for many combinations of mixed single and double weft insertions, still with ANTI-function. • It is also possible to detect three and four wefts moving at the same time, using only one E2070 weft sensor and still with ANTI-function. • The logic current system is very unsensitive to electrical and mechanical interferences. • It is possible to use different weft sensors with current logic output, for example E2016, ANTI, E2010-2 and E2070. When a part of the stop motion need to be replaced it can be advisable to update the stop motion with this board and a suitable weft sensor. Connection When replacing the old board with the 2870 board, just pull the edge connector off the old board and push it on the new 2870 board. The weft sensors are connected with a plug and are easy to replace.
