亮/暗轉換開關:當選配的亮/暗旋鈕旋至位置「L」時,感測器處於亮動作模式。當
選配的亮/暗旋鈕旋至位置「D」時,感測器處於暗動作模式。模式切換時,電源的
綠色 LED 閃爍一次。
表 I 中罗列了传感器无法执行某项功能时应采取的各项措施。

输出信号时当 Alarm 存在且
随后观察到输出信号时,黄色

Yellow LED flashes; if Health
is present then take note of
the corresponding output

原因 /
Cause
无电压或电压低于极限值 /
No voltage or voltage be‐
low the limit values
电压中断 /
Voltage interruptions
传感器损坏 /
Sensor is faulty
尽管传感器准备就绪,但运
行条件不佳 / 此外在 Health-
输出端: 切断了电源 /
Sensor is still ready for ope‐
ration, but the operating
conditions are not ideal/
additionally with health out‐
put: power supply interrup‐

措施 /
Measures
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)
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
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 /
Health 输出端:检查电源,
检查整体电气连接(电缆和
插头连接) /
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. /
