A ligning the lightbarrier F16
The lightbarrierF16 has to be aligned in such a w ay thatitis in line
w ith the edge ofthe contourguide (m aterialstop).
–
Loosen screw s 6 and 7.
–
A lign the lightbarriersupport5 correspondingly.
–
Tighten screw s 6 and 7.
A ligning the lightbarrier F15
The lightbarrierF15 has to be aligned in such a w ay thatthere is a
distance ofapprox.770 m m betw een the needle and the lightbarrier
(basic adjustm ent).
Ifthe knee lining has excess length,the lightbarrierhas to be shifted
to the right.
–
Loosen screw 9.
–
A lign the lightbarriersupportcorrespondingly (approx.770 m m to
the needle).
–
Tighten screw 9.
A djusting the lightbarrier intensity
–
Turn the sensitivity potentiom eter10 atthe frontabove the
light-em itting diode 11 to the leftstop (m inim um sensitivity).
–
Turn the potentiom eterin clockw ise direction untilthe light-em itting
diode 11 sw itches on.
–
Fora safe lightbarrierfunction turn the potentiom eteronce again
in clockw ise direction (one revolution).
Ifthe light-em itting diode does notshine,the lightbarriershould be
cleaned,resetorexchanged.
