Measures
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）完全对准物体 / 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
F. /
Check the operating condi‐
tions: Fully align the beam
of light (light spot) with the
object. / Clean the optical
surfaces . / Readjust the
sensitivity (potentiometer) /
Check sensing range and
adjust if necessary; see
graphic F.
黄色 LED 亮起，光路中无物
体 /
Yellow LED lights up, no
object in the path of the
beam
背景的反射能力过高 /
Remission capability of the
background is excessive
检查背景的变化。降低传感
器灵敏度或使用带背景抑制
功能的探测器 /
Check changes to the
background. Reduce the
sensitivity of the sensor or
use sensors with back‐
ground suppression
光路中有物体，黄色 LED 未
亮起 /
Object is in the path of the
beam, yellow LED does not
light up
灵敏度的设置过低或传感器
和物体之间的间距过大 /
Sensitivity is set too low or
distance between the sen‐
sor and the object is too
long
增大开关距离，注意传感器
和背景之间的间距，参见图
F /
Increase the sensing range,
take note of the distance
between the sensor and the
background, see graphic F
