The status condition when a sensing object is present 
that can be used as a baseline for the lower limit.
2-level Teaching
This is a method of setting the thresh-
old values (1_SL, 2_SL) by two levels 
(P-1, P-2) teaching. 
Select  ‘2-level teaching (        )’ in 
PRO6 mode beforehand.
1Press the [MODE key] once to select ‘TEACH mode’.

3The current teaching method will be displayed, and then the 
unit will enter the ‘P-1’ setting state.
4If the [Jog switch] is pressed while in the status condition 
when a sensing object is present that can be used as a 
baseline for the lower limit, then the display will blink and 
indicate the incident light intensity reading.
 
When using thru-beam type fiber
• Press the [Jog switch] for the sensing object that has the
greatest amount of interrupted light.
 
When using reflective type fiber
• Press the [Jog switch] for the sensing object with the
lowest incident light intensity.
Note) Even if procedures 4 and 6 are reversed, teaching for a 
sensing object with low incident light intensity will 
automatically cause the setting of ‘lower limit value 1_SL’.
