绿色 LED 未亮起 /
Green LED does not light up
绿色 LED 未亮起 /
Green LED does not light up
绿色 LED 亮起，探测物体时
无输出信号 /
Green LED lights up, no out‐
put signal when object is de‐
tected
当 Alarm 存在且随后观察到
输出信号时，黄色 LED 闪
烁 /
Yellow LED flashes; if Alarm
is present then take note of
the corresponding output
signal
探测物体时信号中断 /
Signal interruptions when
object is detected
原因 /
Cause
电压中断 /
Voltage interruptions
传感器损坏 /
Sensor is faulty
未正确连接测试输入端
(TE) /
Test input (TI) is not con‐
nected properly
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
物体表面的去极化特性（例
如：薄膜），折射 /
Depolarizing property of the
object surface (e.g., tape),
reflection
措施 /
Measures
Check the power supply,
check all electrical connec‐
tions (cables and plug con‐
nections)
确保电源稳定无中断 /
Ensure there is a stable
power supply without inter‐
ruptions
如果电源正常，则更换传感
器 /
If the power supply is OK,
replace the sensor
参见 TE 的连接提示 /
See the note on connecting
the TI
检查运行条件： 光束（光
斑）完全对准反射器 / 清洁
光学表面（传感器和反射
器） / 重新设置灵敏度（电
位计）/ 如果已将电位计设置
到最大开关距离：减小传感
器和反射器之间的间距并使
用图 H 检查反射器类型 / 反
射器不适用于所选应用（我
们建议仅使用 SICK 反射
器） / 检查开关距离，必要
时调整；参见图 H. / 传感器
和反射器之间的间距过大 /
Check the operating condi‐
tions: Fully align the beam
of light (light spot) with the
reflector. / Clean the optical
surfaces (sensor and reflec‐
tor). / Readjust the sensitivi‐
ty (potentiometer) / If the
potentiometer is set to the
max. sensing range: Redu‐
ce the distance between
the sensor and the reflec‐
tor, and check the reflector
type against graphic H. /
Reflector is not suitable for
the application in question
(we recommend only using
SICK reflectors) / Check
sensing range and adjust if
necessary; see graphic H. /
Distance between the sen‐
sor and the reflector is too
long
降低灵敏度或更改传感器位
置 /
Reduce sensitivity or
change the position of the
sensor
