LR-ZB250AN/ZB250AP
Supplemental Manual
The "I-DATUM (F-2) mode" for the LR-Z Series memorizes the "Light receiving pattern" the background as a reference surface and detects any changes of the reference surface.
The display value indicates the degree of Consistency of "Light receiving pattern" between the reference surface and the detected object. After setting the reference surface, the displayed value is calibrated toi100. When detecting an object, the value decreases as the degree of Consistency with the reference surface becomes lower. Lower values allow for more stable detection.
This supplemental manual explains the installation method and calibration necessary to detect transparent objects using the "I-DATUM (F-2) mode".
Example 1)
Recommended
The object is close to the reference surface.
The object is closer to the sensor.
Example 2)
Recommended
The sensor is far from the object.
The sensor is closer to the object.
Recommended installation
1. Reference surface
The following background surfaces are recommended for stable detection.
•Matte finished
•Fixed with less vibration
•Dry with no dirt or dust bulid-up
2.Distance between sensor and reference surface
The recommended distance between sensor and reference surface is 70 to 150 mm.
3. Position of the object to be detected
For stable detection, put the sensor as close as possible to the object to be detected and also keep it as far away as possible from the reference surface.
4. Beam axis of the sensor
Tilt the beam axis of the sensor as much as possible against the reference surface. (10° or more)

Setting procedure
1. Switch the mode.
Switch the operation mode of LR-Z to "I-DATUM (F-2)".
Press and hold the [DOWN] button for 3 seconds or more.
Press the [UP] button and [Down] button at the same time.
Press the [UP] button.
10° or more
Tilt the beam axis downward.
70 to 150 mm
It can also be tilted to the right or left.
10° or more
Press the [UP] button to switch the operation mode to “I-DATUM (F-2) mode”.
Press and hold the [DOWN] button for 3 seconds or more to complete the setting.
With the “I-DATUM (F-2) mode”, the left end of 7 segment display will always illuminate.
Set the reference surface next.
