[ 2 ] Conditions for Connecting LTB3 to The Loom
To connect LTB3 to each loom, the following power voltage and signals must be supplied from the
loom:
• Necessary power voltage
• 12 VDC (LTB3 board drive voltage)
Voltage:
Current consumption: Within 0.5 A
• Necessary signals
• Production pulse signal (mandatory):
Production pulse signal output at a rate of one pulse per pick
• Stop signal (run/stop) (mandatory):
Signal that is open during running and close during stopping
• Weft miss stop signal:
Signal that is close during a weft miss
• Warp miss stop signal:
Signal that is close during a warp miss
• Selvage miss stop signal:
Signal that is close during a selvage miss
• Leno miss stop signal:
Signal that is close during a leno miss
• Manual stop signal:
Signal that is close during manual stop occurrence
[ 3 ] Loom Side Signal I/F Circuit Diagram
The recommended signal I/F circuit on the loom side is shown below. Since the production pulse
signal repeats ON and OFF at a high speed, a transistor is used.
