The M120 optic is connected to the lower connection (4 Pol.) on the back of the
light barrier cabinet (
figure 11.17 ).
Adjustment Procedures
1. Adjustment of the angle of inclination (tilt):
The magazine belt position should be unoccupied.
The Distance Adjustment Screw ( figure 11.18 ) is set on maximum „FAR“.
With a reflective background a reduction of the distance adjustment is pos-
sible. The Distance Adjustment Screw is turned counter clockwise to
„NEAR“ until the display „OPE“ is no longer activated (this provide an in-
crease in the aperture of the background).
The optic is first adjusted as far as possible to the bottom, until the maga-
zine belt is detected, then turned back gradually until the belt can no longer
be detected.
You must ensure that the M120 optic detects a sample only in the outside
magazine belt position, not the inside position.
2. Adjustment of the distance:
The magazine belt position should be occupied.
The Distance Adjustment Screw is set on minimum „NEAR“.
Turn the Distance Adjustment Screw clockwise to „FAR“ until the display is
activated.
Note: Excessive dust or dirt at the lens surface of the optics reduces the optics
recognition performance. Keep these surfaces clean.
