„ Operation mode (Fnc)
The “Distance (F-1)” mode detects distance.
“I-DATUM (F-2)” memorizes the “Light receiving pattern” and detects the amount of
change from the reference surface. Even a subtle uneven part can be detected if the
surface condition or color is different. Also, this mode is suitable for the detection of
transparent objects.The display value is “i100” for the background (reference surface) and
the figure decreases when the target object is detected.
z Setting procedure in I-DATUM mode (F-2)
1. Set the operation mode to “I-DATUM (F-2)”.
2. Set the reference surface.
z Standard tuning
1. Press the [SET button] briefly (<1s).
2. Press and hold the [SET button] (>3s).
[DTM indicator] will illuminate.
z High sensitivity tuning
1. Press and hold the [SET button] (>3s).
[DTM indicator] will not illuminate.
If no detection is achieved with the standard tuning, use the high sensitivity tuning.
When detecting transparent objects, refer to the “LR-ZB250AN/ZB250AP supplemental
manual”.
You can download the “LR-ZB250AN/ZB250AP supplemental manual” from the
KEYENCE homepage.
„ External input (in)
Turning the external input line (white line/(2) pin) ON will enable the following functions to
be performed.
z Tuning ()
This performs the same function as the [SET] button.
z Transmission OFF ()
This turns off the laser diode.
z Adjust (Adj)
Sets the reference surface. There is no limit for the number of times of setting. The
setting is reset by turning ON/OFF.
„ DSC function (dC)
This can be set when the operation mode is set to “I-DATUM (F-2)”. This mode
automatically corrects the reference surface to “i100” if changes due to temperature
change or build-up occur. If the display value largely fluctuates on the reference surface,
set the DSC function to [High speed (hiF)].
