ADJUSTMENT OF DETECTION AREA
■Detection area adjustment method
Detection distance adjustment
Indicator
Area selector
Alignment lever
For LED on
Slide the alignment lever
to the right, and latch it.
Horizontal direction adjustment
Turn the mirror unit to the direction
you want to protect to adjust the
detection area.
(±45° adjustable [in 5° steps])
The detection area and detection operation can be optimized as follows:
• Operating the area selector enables adjustment to the distance of the detection area.
• Turning the mirror unit enables the user to adjust the detection area in a horizontal direction.
Locking screw
Detection distance [fine adjustment] using LED area checker
To enable fine adjustment mode slide the two alignment levers to the right and latch
into place, this will activate the alignment LEDs. Look at the sensor to check the
sensitive zones, the mirror surfaces will appear red or green when standing inside the
detection area. Use the horizontal direction adjustment to fine-tune as required.
Stand at the maximum distance of your desired coverage and adjust the area selector
so that the red mirror surface is visible between shoulder and chest height, and the
green mirror surface is visible between waist and knee height.
Note: the mirror surfaces will appear unlit when standing
outside of the detection area.

When the detection area is adjusted to less than
66'(20m), adjust it using supplied area masking sheet.
and set "ON" in the short distance setting (dip switch 5 in
mode selector 2)
(Refer to "4 DETECTION AREA" , "7 FUNCTION")
[Example 1] Low position mode
Mounting height : 6.6'(2m)
To set the maximum distance to 115'(35m) :
[Example 2] Middle position mode
Mounting height : 10'(3m)
To set the maximum distance to 66'(20m) :
Choose area selector [B/C]
[Example 3] High position mode
Mounting height : 20'(6m)
To set the maximum distance to 135'(40m) :
Choose area selector [C]
Locking screw can be tightened both from left and right, but the
tightening direction is different.
Tighten the screw as indicated on the plate.
Detection distance [rough adjustment]
Refer to the area setting table inside the sensor unit,
and set the detection area corresponding to the
installation site using the area selector and indicator.
Then tighten the locking screw. (When moving the
area selector up and down, the indicator will show the
letters from A to E. Select the position based on the
installation height and maximum detection distance.)
[Example] Middle position mode
Mounting height : 10'(3m)
To set the maximum distance to 100'(30m) :
Choose area selector [B]

When the zone faces toward a place where false operation can
occur (refer to "3 PRECAUTIONS), adjust or mask the area to
avoid.
When the adjustment has
been completed unlatch both
alignment levers and ensure
they return to the left edge of
each mirror unit.
If the levers are not returned
to the original position the
unit will issue a continuous
alarm output and the alarm
LED will illuminate.
