PCB arrival sensor
● LE4-M951H-00X FIBER SENSOR FX-100 Series (SUNX)
■ Adjusting Method
① Sensor Installation and Adjustment
The optical receiver of PCB Arrival Sensor has to be set within 60 to 70 mm from the conveyor guide,
and the optical axis has not to be interfered by any parts of the conveyor.
NOTE: It should be confirmed that nothing interferes with the optical axis by the minimum conveyor width.
② Confirm the harness of the fiber sensor is locked.
NOTE: If it has not been locked properly, the function might be unstable.
The sensor harness must be locked certainly after it has been inserted.
③ Check the indication value of the received optical light.
The indication value should be from 2000 to 3800.
If it is lower than 2000, it is necessary to readjust the fixed position of the sensor in Item ①.
*Do not change the threshold value (the factory setting; “40”).

④ Set up the threshold follow-up cycle of the fiber amplifier.
Set “Shift Quantity” to 25% and “Follow-up Cycle” to 10 seconds.
Press key more than 4 seconds in the normal detection condition.
Proceed to “ Pro Mode” and change to threshold follow-up cycle setting automatically.
Press key to show “ 25P” .
Press key two times.
【NOTE】Check that the threshold has been 25% to the received light value.
The threshold will be still low just after setting.

⑤ Set up the code setting
Press keys at the same time for four seconds.
⑥ Finally, adjust the conveyor width to the minimum, and then confirm that the conveyor does not
interfere with the sensor and PCB can be detected when loading PCB.
