措施 /
Measures
绿色 LED 未亮起 /
Green LED does not light up
无电压或电压低于极限值 /
No voltage or voltage be‐
low the limit values
检查电源，检查整体电气连
接（导线和插头连接） /
Check the power supply,
check all electrical connec‐
tions (cables and plug con‐
nections)
绿色 LED 未亮起 /
Green LED does not light up
电压中断 /
Voltage interruptions
确保电源稳定无中断 /
Ensure there is a stable
power supply without inter‐
ruptions
绿色 LED 未亮起 /
Green LED does not light up
传感器损坏 /
Sensor is faulty
如果电源正常，则更换传感
器 /
If the power supply is OK,
replace the sensor
，黄色 LED 闪烁 /
Yellow LED flashes
尽管传感器准备就绪，但运
行条件不佳 /
Sensor is still ready for ope‐
ration, but the operating
conditions are not ideal
检查运行条件： 光束（光
斑）完全对准背景 / 清洁光
学表面 / 重新设置灵敏度
（电位计） / 检查开关距
离，必要时调整；参见图
