This function calibrates the reference state to ".0" and the state at which the received
light intensity is slightly higher as "100.0".
This function is useful with the reflective model to detect while using the background
as a reference.
Enabling the maximum sensitivity preset function
1
When no workpiece is present for the
reflective model, or when a workpiece is
present for thrubeam model/retro-
reflective model, press and hold the
[PRESET] button for 3 seconds or more
while the PST indicator is OFF.
Release the button when "Auto" flashes.
Calibration is complete after the setting
value flashes momentarily, and then stops
(lights up).
The PST indicator lights in green, and the
setting value is set to "50.0".
• The maximum sensitivity preset function cannot be executed when
the received light intensity is saturated (higher than the value
listed in the Extension display on page 4-30). ("---- ----" will
appear during step 1.)
• The maximum sensitivity preset function cannot be used when the
LV-NH100, NH110 or NH300 is connected, but by holding down the
[PRESET] button in the light ON state, the amount of light blocked
at light intensity .0 and light block 100.0 is displayed.
Disabling the maximum sensitivity preset function
When the PST indicator is lit, press and hold the [PRESET] button.
• The PST indicator turns off, indicating that the maximum sensitivity preset func-
tion has been disabled.
