Circuit Diagram
B Limitedteaching
In the case of small objects and backgrounds
1 Press “SET” key when in a background state or there is a detected object.
2 With the background object as the reference, press the “UP” key to set the reference value in the sensor.When the object is detected as the reference, detecting the set value of the objec after press the ” DOWN” button
3 Complete calibration
C 1 Pointteaching(windowcomparemode)
The method of setting upper and lower limit values is implemented instead of implementing 1- point teaching for the distance between the reference plane of the detected object.Use this function when discriminating within the upper and lower limits.
In the case of implementing 1-point teaching (window comparison mode),please set the detection output setting in PRO mode to [1 point teaching (window comparison mode)] in advance.
Specifications
D 2 Pointteaching(windowcomparemode)
In the case of implementing 2-point teaching (window comparison mode),Please set the detection output setting in PRO mode to [2-point teaching (window comparison mode)] in advance.
When teaching, please use the detection product (P-1, P-2) with different distance.
- Press the “SET” button (1st time) when there is a detected product P-1
- Press the “SET” button (second time) while detecting product P-2 Complete calibration
E 3 point teaching (window compare mode)
Perform 3- point (P-1, P-2, P-3) teaching, as shown in the following picture, and set the reference value 1_ SL between the 1st and 2nd times.
Set the reference value 2 SL between the 2nd and 3rd times,and the method of setting the reference value range.
In the case of 3-point teaching (window comparison mode),Please set the menu detection output setting to [3 point teaching (window comparison mode)] in advance. When teaching, please use the detection product (P-1, P-2,P-3) with different distance.
After teaching, P-1, P-2, and P-3 will be automatically arranged in ascending order.
Press the “SET” button (1st time) when there is a detected product P-1.
Press the “SET” button (second time) while detecting product P-2.
Press the “SET” button (3rd time) while detecting product P-3.
Complete calibration
Threshold Fine Tuning Function
No rma l l y d e t e c t i o n mo d e ： Press the “UP” or “DOWN” keys to directly change the threshold
W i n d ow c omp a r i s o n mo d e ： Short press the “M” key to to switch threshold 1 and threshold 2.
Zero Adjustment Function
Note: Zero adjustment requires setting the display mode to reverse mode in order to operate.
The zero adjustment function means the function of forcing the measured value to be “set to zero”. When setting zero adjustment, there is a vertical line on the screen, as shown in the right picture:
Press the “M” and “UP” keys meanwhile to zero adjustmentsetting
Press the “M” and “UP” keys meanwhile to cancel the zero adjustment
Key Locking Function
Press the “M” and “DOWN” keys meanwhile to lock the keys.
Press the “M” and “DOWN” keys meanwhile to unlock.
Press and hold the “M” key for 3 seconds in the distance display interface to enter the menu setting mode. In menu setting mode, press and hold “M” for 3 seconds to exit menu setting mode.
After enter the menu setting mode, Do not press any keys within 20 seconds, will exit the menu setting mode. press the “UP” or “DOWN” keys to switch menus up and down.Short press the “SET” key to enter the corresponding menu
(6) External input: when selecting the corresponding function, short circuit the pink wire to the negative pole of the power supply once( more than 30ms) to ttrigger once;
Zero adjustment: The current value is reset to zero (only valid if the display mode is offset or reverse)
Teaching: It can be used as a single press ofthe “M” button
Stop measurement: The sensor stop continuous measurement and stop emitting laser at the same time.
(8) Displaymode:Standard(actualdistance),reverse(thecenterpointoftherangeis0 points, the direction close to the sensor is positive, and vice versa is negative), offset (the farthest range is 0 points, and the distance close to the sensor direction increases)
(9) The default is keep off, and you can select keep on by use “up” and “down” buttons, when the current detection value reaches the maximum or minimum, the output voltage or current can be maintained.【 A common application is to maintain 0 or 5v even after exceeding the range. 】
