If the alignment is correct: a reflection occurs at the surface 7 of the
bobbin hub when an empty bobbin rotates. The figure between 1 and
15 will show the intensity of the reflection. If the value is above ( 8 ),
then a line (
¾
) will be displayed. You will hear a beep at the same
time.
left bobbin
right bobbin
actual reflection value 3
no line, value <8
line, when value >8
actual reflection value 15
Hint:
If the light barriers are set properly, the maximal value of 15 must be
reached when the infrared ray hits the surface of the bobbin hub.
– To exit the test program switch off the machine.
Correction
–
Clean the lenses of the light barriers 2 and 6 as well as the
reflection faces 7 of the bobbin hubs with a soft cloth.
–
Loosen the clamping screw 1 and 4 respectively.
–
Align the light barrier 2 and 6 respectively by a minimum rotary
motion on the holders 3 or 5.
The infrared ray of light barrier 2 or 6 must hit the bobbin hub
through the light window in the bobbin case without hindrance.
–
Tighten clamping screw 1 and 4 respectively.
–
Check the alignment of the two light barriers once again.
