Adjustment Steps
1. Install, wire, and turn ON the Photomicrosensor.
2. Perform teaching (mark registration). Refer to Mark Registration
(Teaching).

Refer to the following for each teaching method. Remote one- or two-
point teaching is possible. Refer to Remote Control Function.
One-point Teaching
1 Set the mode selector to TEACH.
2 Locate the mark to the sensing position and press the SET but-
ton. Then all the red threshold indicators are ON.

3 Set the mode selector to RUN. The output will be ON whenever
the set mark is detected.
Note: By teaching on the base, reversed output as shown above (base: ON,
mark: OFF) can be obtained.

teaching with no po-
sitioning is desired.

Auto-teaching
The threshold level is
set between color of
the mark and base.
The output is ON
when the mark (i.e.,
the color with shorter
passing time) is de-
tected.
Red threshold indicators are ON.
3. Make fine adjustments of the threshold level if necessary. Refer to
Threshold Level Adjustments on page A-139 .
4. Check that the mode selector is set to RUN.
Two-point Teaching
1 Set the mode selector to TEACH.
2 Locate the mark to the sensing position and press the SET but-
ton. All the red threshold indicators will turn ON.

3 If teaching is successfull, move the mark and press the SET
button at the base.
• If teaching is successfull, all the green detection level indica-
tors are ON.
• If teaching is unsuccessfull, all the red threshold level indica-
tor flash.

4 If teaching is successful, set the mode selector to RUN to com-
plete the teaching operation. If teaching is unsuccessful, restart
from the above step 2.
Note: Follow the above steps so that the output will be turned ON whenever the
mark is detected. By taking the opposite steps, the output will be turned
OFF whenever the mark is detected and turned ON whenever the base
is detected.
