警告输出端:传感器 (WLG4S-3) 通过预先停机输出端(接线图 [B] 中的"警报")发
送命令,输出端仅在传感器准备就绪受限时发送消息。潜在原因:传感器或反射器
脏污,未调节传感器。状态良好:LOW (U
V)。此时,LED 指示灯闪烁。
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。
LED 指示灯 / 故障界面 /

绿色 LED 未亮起 /
Green LED does not light up

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

探测物体时信号中断 /
< V),脏污严重时则为 HIGH (>+U
V
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 /
Sensor is still ready for ope‐
ration, but the operating
conditions are not ideal

如:薄膜),折射 /

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 / 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 / Reflector is not suitable
for the application in questi‐
on (we recommend only
using SICK reflectors) /
Check sensing range and
adjust if necessary; see
graphic H. / Distance bet‐
ween the sensor and the re‐
flector is too long
降低灵敏度或更改传感器位
置 /
