可在 0 至 2 秒之间设置时间等级。
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。

当 Health 存在且随后观察到
输出信号时当 Alarm 存在且
随后观察到输出信号时，黄色
LED 闪烁 /
Yellow LED flashes; if Health
is present then take note of
the corresponding output
signal; if Alarm is present
then take note of the corre‐
sponding output signal
黄色 LED 亮起，光路中无物

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/

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. / 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
object. / Clean the optical
surfaces . / Readjust the
sensitivity (potentiometer) /
Check sensing range and
adjust if necessary; see
graphic F. / With health out‐
put: Check the power sup‐
ply, check all electrical con‐
nections (cables and plug
connections).
降低开关距离，参见图 F /
Reduce the sensing range,
