Panasonic LS-400 Series - Teaching Mode (When Using Normal Mode)

4-2. Teaching Mode (when using normal mode)
2-level teaching is a method of setting the ‘threshold value’ by teaching the amplifier two different
status conditions - sensing object present and sensing object absent. The ‘threshold value’ is
usually set using this method.
The ‘threshold value’ can be set by utilizing three kinds of teaching, whichever ‘2-level teaching’, ‘limit teaching’ or
‘full-auto teaching’.
* Select output 1 and output 2 and the sensing mode beforehand.
Place a sensor head within sensing range.
Press the
MODE key once.
Status condition - sensing object is present
Press the
Jog switch.
Press the
Jog switch.
()
Status condition - sensing object is absent
Difference between incident light
intensities is not great enough.
Stable sensing
Press the
MODE key 5 times.
2-level Teaching
1Select ‘TEACH mode’ by pressing the [MODE key] once.
2Press the [Jog switch] when in the status condition of -
sensing object is present.
4Press the [Jog switch] when in the status condition of -
sensing object is absent.
7The incident light intensity (red) will again be displayed,
indicating that configuration is now complete.
8By pressing the [MODE key] 5 times, the amplifier will return
to ‘RUN mode’ (normal sensing operation).
5The digital display will again blink the incident light intensity
reading (red) and the ‘threshold value’ will be set to a value
midway between the incident light intensities when the
sensing object is present and when it is absent. The blinking
MODE indicator / TEACH will stop blinking and continuously
light up.
* Fine adjustment of the ‘threshold value’ can be performed
in the RUN mode.
6The set ‘threshold value’ (green) will indicate and the
sensing stability status will be displayed.
• When stable sensing can be performed
n The digital display will blink the word ‘ ’ (red).
• When stable sensing cannot be performed
n The digital display will blink the word ‘ ’ (red).
3The digital display will indicate the incident light intensity
reading (green), then the MODE indicator / TEACH (yellow)
will blink.
This indicates that the second point item is now ready for
input.
