2-level Teaching
This is a method of setting the threshold values
(1_SL, 2_SL) by two levels (P-1, P-2) teaching.

The symbol ‘

displayed repeatedly.
Press the
MODE key 5 times.
Upper and lower limits have
not been correctly set.
The status condition when a sensing object is present
that can be used as a standard for the lower limit.
The status condition when a sensing object is present
that can be used as a standard for the upper limit.
2The current teaching method (green) and incident light
intensity (red) will be displayed and the amplifier will enter
the ‘P-1’ setting state.
4The amplifier has entered the ‘P-2’ setting state and ‘ ’
(green) will blink.
7Then the setting for ‘upper limit value 2_SL’ (green) will be
displayed.
8By pressing the [MODE key] 5 times, the amplifier will return
to ‘RUN mode’ (normal sensing operation).
‘Lower limit value 1_SL’ (green) and incident light intensity
(red) will be displayed.
6The display will indicate whether the upper and lower limits
have been correctly set and the setting for ‘lower limit value
1_SL’ (green) will be displayed.
• If ‘ ’ (red) is blinking…the upper and lower limits have
been set correctly.
• If ‘ ’ (red) is blinking…the upper and lower limits have
not been set correctly.
5If the [Jog switch] is pressed while in the status condition
when a sensing object is present that can be used as a
standard for the upper limit, then the display will blink the
incident light intensity reading (red).
When using retroreflective type sensor head
• Press the [Jog switch] for the sensing object that has the
least amount of interrupted light.
When using reflective type sensor head
• Press the [Jog switch] for the sensing object with the
greatest incident light intensity.
3If the [Jog switch] is pressed while in the status condition
when a sensing object is present that can be used as a
standard for the lower limit, then the display will blink and
indicate the incident light intensity reading (red).
When using retroreflective type sensor head
• Press the [Jog switch] for the sensing object that has the
greatest amount of interrupted light.
When using reflective type sensor head
• Press the [Jog switch] for the sensing object with the lowest
intensity of incident light.
Note) Even if procedures
3
and
5
are reversed, teaching for a
sensing object with low intensity incident light will
automatically cause the setting of ‘lower limit value 1_SL’.
1Select ‘TEACH mode’ by pressing the [MODE key] once.
