Teaching Selection
■ Auto-tuning
It is suitable for the sensing environment in which fast-moving objects make unstable
incident light levels. Also, it is convenient because the object maintains its movement
continuously during the teaching mode. It uses the average value of the incident light
level estimated a certain period of time.
■ 1-point teaching
It is suitable for the sensing environment where much dust or pollutant makes the
lower incident level. The teaching proceeds; through-beam type: with sensing target,
reflective type: without sensing target
■ 2-point teaching
It is suitable for the sensing environment in which the object moves slowly or stops
with stable incident light level. After the teaching 2 points (with/without sensing
target), set the average value as a teaching value.
■ Positioning teaching
After placing the sensing target to the desired position, set 90% of the incident light
level as a teaching value. Typically, it is available for detecting a small hole on the
surface (through-beam type) or detecting moving object having a curve (reflective
type).
Teaching Sensitivity Setting
•
Before setting the sensitivity, select the teaching mode suitable for the sensing
environment. Refer to the detailed explanation of the teaching mode.
•
To use the teaching sensitivity setting by external input, select P-8. External input to
the teaching sensitivity setting (SET).
