Note
Be sure that the mounting height is ithin the value of
those in "SPECIFICATION."
1Remove the cover and attach the sensor ith scre s.
Plug the Connector for the sensor to that for the cable.
Supply po er to the sensor. Adjust the detection area
and set the various S itches. (See “ADJUSTMENT.”)
Note
Make sure that you connect the cable correctly to the
Control Unit of the door before turning the po er on.

Setting the Presence timer
1st Ro and 2nd Ro from
door provide the presence detection.
(1) Select the presence detection time.

Setting the Frequency Function
(Interference Prevention)
Four different frequencies can be
set by adjusting the Dips itch 3
and 4.
Note When t o or more sensors are installed close to each
other, it is possible that they interfere. When that happens,
change the Frequency.
Setting the Sno mode
Set the Dips itch5 and 6 to sno
mode , if the sensor is used in a
region ith sno or a lot of insects.
