Mount back lighting transmitter as illustrated.
In confined mounting spaces the transmitter may be rotated at an
angle of 30° around the pivot. The amount of light received by the
color line sensor will however be reduced a little as a result.
The color line sensor differentiates between light and dark lines
and contrasting edges. For this reason sensors used in the back
lighting process must be directly aligned to the back lighting transmitter
lamps as otherwise a sufficient amount of light cannot be
assured.
Please ensure that the insulation is not damaged and leads are
properly secured and protected. Protect and run signal lines away
from heavy-current carrying leads .
The color line sensor housing with drill holes (see figure opposite)
must be connected to the machine frame. Due to the metal connection,
heat dissipation via the assembly connection may additionally
occur.
Run the electrical leads according to the attached wiring diagram
and protect with a strain release device.
Tighten the connection lead union nut. It assures a conductive
connection between the color line sensor housing and the signal
line shield.
The sharpness setting must be performed for precision color
line sensor operation!
Connect web guider to the operating voltage.
Pivot
Position sensor on the web. The guiding criterion that is to be
scanned must be located at the position of the middle orange light
spot (set position).
As guiding criterion for the sharpness setting we recommend an
uniform black line on a white background, with a line width of
1 mm. If such a guiding criterion is not available, a simple paper
print-out may be used as a substitute. If using a paper print-out
please ensure that the paper is clean (without creases and folds)
and rests on the web at the correct distance.
