KEY LOCK FUNCTION
●
The key lock function prevents key operations so that the conditions set in each
setting mode are not inadvertently changed.
●
If operating key switch after key lock is set, “

TEACHING MODE
Be sure that detection may become unstable depending on the use environment in
teaching if less margin is applied.
●
Teaching can be set in RUN mode.
Useful when sensing object can be set
2-point teaching
This is basic teaching method.

Stable sensing is possible
1.
Press the SET key in the sensing object present condition.
2.
Press the SET key in the sensing object absent condition.
Stable sensing is not possible
Useful when sensing object cannot be set
Limit-teaching
This is teaching method in case small object or object in
back ground are existing.
<Common to thru-beam type, mirror reflection type and reflective type>

Stable sensing is possible
1.
Press the SET key in the sensing object present
condition or non sensing object present condition.
2.
Thru-beam type, mirror reflection
type: Threshold level is shifted to
high value (low sensitivity) when UP
key is pressed down, and it is shifted
to low value (high sensitivity) when
DOWN key is pressed down. (Note)
Reflective type: Threshold level is
shifted to high value (low sensitivity)
when DOWN key is pressed down,
and it is shifted to low value (high
sensitivity) when UP key is pressed
down. (Note)
Stable sensing is not possible
Note: The shift value of approx. 15% is an initial value. Display of the shift value can be changed to
percentage [approx. 0 to 999% (unit 1 %)] or incident light intensity [0 to 9999 (unit 1)].
For setting the shift amount, refer to <PRO1> in “

Useful when not want to stop production line and to keep the sensing object move
Full-auto teaching
This is method to conduct teaching doing sensing
object is moving.
