If the sensor is installed on a tilted pole, it will see the
ground and not operate properly. Make sure to install
the sensor on a pole that is vertical to the ground.
If the pole cannot be installed vertically because of
sloping ground, etc., install it in a position such that it is
500mm (20in.) above the ground at the set detection
range (depending on the application).
However, the detection capability may be reduced as
compared to a sensor installed vertically to the ground.
• There should not be irregularity on the ground in the
sensor' s detection area such as gratings (refer to
"10-2 Detection Area Diagram" (p. 37)). In such a
place, the sensor may not go into the non-detection
status or may be slow to change to that status.
• Do not install any moving object such as flags
orbanners in the correct space detection area.
Remove any vegetation from the detection area, or
reconfigure the detection area to be smaller. In such a
place, the sensor may not go into the non-detection
status or may be slow to change to that status.
• Do not use a fluorescent lamp around the detection
area. It may prevent proper operation of the sensor.
