Place a sensor head within sensing range.
Press the
MODE key once.
Press the
Jog switch.
Status condition - sensing object is absent
Press the
MODE key 5 times.
Shifting can be performed. Shifting cannot be performed.
Teaches only the status condition in which no sensing object is within sensing range (status in
which incident light intensity is stable). This method is used to set a ‘threshold value’ for
conducting sensing in the presence of a background, or when extremely small objects are to be
detected.
Limit Teaching
The digital display
will scroll.
Turn the Jog switch
in the ‘
’ or ‘’
direction.
1Select ‘TEACH mode’ by pressing the [MODE key] once.
2Press the [Jog switch] when in the status condition of -
sensing object is absent.
3The digital display will indicate the incident light intensity
reading (green), then the MODE indicator / TEACH (yellow)
will blink.
4Turn the [Jog switch] in either the ‘’ or ‘’ direction.
When using retroreflective type sensor head
When using reflective type sensor head
• If the switch is turned toward the ‘
’ direction, the digital
display will scroll from the left to the right and the threshold
value will be shifted down by approx. 15 %, to a value lower
than the incident light intensity displayed (high sensitivity).
• If the switch is turned toward the ‘
’ direction, the digital
display will scroll from the right to the left and the threshold
value will be shifted up by approx. 15 %, to a value higher
than the incident light intensity displayed (low sensitivity).
*
The initial factory-set value of the shift amount is approx. 15 %.
The shift amount can be changed by utilizing the ‘5-4. Shift
Function’ from ‘PRO1 Mode’, described on p. 27. (The
percentage adjustment is variable from approx. 5 % to 200 %,
in increments of 1 %.)
6
The incident light intensity (red) will again be displayed,
indicating that configuration is now complete.
7By pressing the [MODE key] 5 times, the amplifier will return
to ‘RUN mode’ (normal sensing operation).
5The set ‘threshold value’ (green) will indicate and the
judgement on whether the shift amount can be shifted or not
will be displayed.
• When the shifting can be performed
n The digital display will blink the word ‘ ’.
• When the shift amount cannot be changed because the
setting exceeds the upper or lower display limit (the value
is reset to within the upper and lower limits)
n The digital display will blink the word ‘ ’.
