Fault finding
Possible causes
Remedies
1.
Switch failure
Replace stopper housing cover.
2. Fuses blown - Feeder
Check fuse. If broken, replace circuit board.
3. Fuses blown - Interface
Check fuse. If broken, replace fuse or circuit board.
4. Motor stator damaged
Check stator resistance with Ohm-meter.
5. Rotor blocked
Check if the winding disc rotates freely.
6. Rotation sensor not connected
Check that the rotation sensor connector is properly
connected to the circuit board.
7. Magnet not connected
Check that the magnet connector is properly connected
to the circuit board.
8. Sensor board not connected
Check that the sensor board connector is proberly
connected to the circuit board.
9. Motor not connected
Check that the motor connector is properly connected.
to the circuit board
10. Wrong reserve sensor settings
Adjust sensor sensitivity settings (loom terminal).
11. Wrong winding sensor settings
Adjust sensor sensitivity settings (loom terminal).
12. Wrong yarn-break sensor settings
Adjust sensor sensivitity settings (loom terminal).
13. Yarn break sensor not activated
Activate yarn break sensor (loom terminal).
14. Yarn break sensor not connected
Connect yarn break sensor.
15. External sensor selected, but not
Set “internal” yarn break sensor (loom terminal)
installed
or install external sensor.
16. Yarn break sensor set to “internal”
Set “external” yarn break sensor (loom terminal).
17. Input yarn tension too low
Adjust input tensioner.
18. Input yarn tension too high
Adjust input tensioner.
19. Loom main power off
Switch loom “main power” on.
20. Loom “stand by” switch off
Switch “stand by” on.
21. Feeder not clean
Remove dust and fibres, clean sensor window (see page 10).
22. Sensor not clean
Remove dust and fibres, clean sensor window and mirror (see page 10).
23. Sensor damaged
Replace sensor.
24. Motor circuit board damaged
Replace motor circuit board.
25. Interface board damaged
Replace interface circuit board.
26. Power failure
290V/ 24V DC failure. Check interface and feeder fuses,
check voltage level.
27. Feeder motor failure
Check feeder motor coil resistance.
28. Incorrect distance between fixed finger
Adjust gap.
and stopper unit
29. Yarn break indication
Rethread feeder.
