Basic Usage
Setting the Threshold (Teach Function)
3
With an object present, hold down
TEACH
ESC
for 1
second or more.
The output indicator of the channel (output 1 or
output 2) for which the teach function is being
executed blinks once in orange.
* Steps 3 and 5 can be performed in any order.
4
When the product is taught the received
light amount of the first point, the numeric
value blinks, then the product is set for the
execution of the teach function at the
second point.
5
Place the other object, and then hold down
TEACH
ESC
for 1 second or more.
* If approximately 30 seconds elapse with
TEACH
ESC
not
being held down, the teach function will be
canceled, and the threshold will not be set.
6
The product is taught the received light
amount of the second point, and the
threshold blinks.
This completes the execution of the teach function.
The OLED display automatically returns to the
RUN screen.
* If the received light amount does not meet the
conditions required for the teach function, “Teach
error” will be displayed. If this error is displayed,
refer to

“5-1 Error Displays” (page 5-2) for
troubleshooting.
MEMO

After executing the teach function, to reset the teaching with the same mode again, simply hold down the
TEACH
ESC
key for
1 second or more. (The operations in steps 1 and 2 of the operation procedure are not necessary.)
In this situation, the teach function is executed with the previously set mode.
