If teaching is not stable:
The threshold indicator (red) will flash. The built-in buzzer will

beep 3 times.

Change the position of the object and the sensing distance

that has been set and repeat the process.

for 0.5 to 2.5 s

3. Set the mode selector to RUN. Be sure that the middle

threshold indicator is lit. The threshold will be set to a 50%

value.

One-point Teach Mode

1. Set the mode selector to TEACH.

Press the SET button once without a target object in the

sensing area. Be sure that all the threshold indicators (red)

are lit. The built-in buzzer will beep once when the threshold

indicators are lit.

Press once for 0.5 to 2.5 s

2. Set the mode selector to RUN. The threshold is set automati-

cally.

3. The Sensor will automatically compensate for environmental

changes.
