1. Go to the SP5-102-203 (input check SP for the proximity sensor).
2. Cover the sensor with 10 sheets of plain paper, and then execute the
SP. Make sure that it becomes "0". (Do not place your hand near the
sensor, even over the paper, when covering the sensor)
3. Remove the paper from the sensor and make sure that it becomes
"1".
4. If the sensor reacts normally in step 2 and 3, check if there are any
other possible factors around the machine that may cause the
temperature change such as a heater or a fan. (Deal with the issue as
necessary)
5. Replace the proximity sensors and proximity sensor board if an
abnormal value is detected during steps 2 and 3.
6. Turn on the main power on and perform steps 1, 2, and 3 again.
7. If the SC is not solved, turn the main power off and replace the
harness which connects the proximity sensors and the proximity
sensor board.
8. If the SC is still not solved, there is a possibility that other parts of the
machine such as the connector at the controller side or the harness
between proximity sensor board and IPU are broken.
