Installation instructions
For detecting the moving direction of the object, please pay attention to the installation direction of the sensor. The fastening torque should be below 0.8N m.
Setting method
Before setting up the instruction, confirm the light intensity mode or the color mode. The "COLOR" green indicator is always bright is color mode and extinguished as a color intensity mode.
Two point setting method
①When the projection light of the sensor against the measured color, presses the "ON" button, and the "GOOD" green indicator lights flicker.
②When the projection light of the sensor against the background color, presses the "OFF" button.
③When the threshold value set between steps ① and ② is stable, the "GOOD" green indicator light is always bright,vindicating that it can start normal detection. When the threshold value set between steps ① and ② is not stable, the "ERR" red indicator flashes for 3 seconds and revert to the last set state.
④If you want to switch NO (normally open) to NC (normally closed) output mode, you need to change the order of steps ① and ②.
Threshold value adjustment
①Press the "ON" button for more than 5 seconds until ERR, GOOD and COLOR three indicators flicker simultaneously.
②Press the "OFF" button to adjust the threshold value.
The relationship between the return difference state and the light flicker is as follows:
State | Indicator 
| Three indicator flicker |
Return difference value small | 
| only the color indicator flicker |
Return dirrerence value medium | 
| GOOD、COLOR indicator flicker together |
Return difference value large | 
| ERR、GOOD、COLOR 3 indicator flicker together |
Exit threshold value adjustment
Under the condition of threshold adjustment, press the "ON" button for more than 5 seconds until the three lights of ERR, GOOD, and COLOR stop flashing, that is, the threshold return adjustment is withdrawn.
About false information hints
When error messages appear, please follow these methods.
Indicator light state | The "ERR" red indicator is always lit and will not be extinguished automatically. |
Error information content | The output line load is short circuited, and the overcurrent goes through. |
Handle | After turn off the power supply, check the output line load. |
Warning
• This product is only for target detection. Do not use this product to protect human body or body parts.
