5)
6)
When adjusting the sensitivity of OUT 1 area, adjacent right OUT 1 area and adjacent left
OUT 1 area, this is the OUT 1 area operation indicator (red).
When adjusting the sensitivity of OUT 2 area, this is the OUT 2 area operation indicator
(yellow).
Set areas other than the area you are adjusting as ineffective.
Use the accessory adjuster screwdriver to turn the distance adjuster slowly. Turning with
excessive force will cause damage the adjuster.
During the sensitivity adjustment, do not let your hand be detected.
Sensitivity adjustment for the auxiliary sensor is performed with the sensitivity adjuster on
the auxiliary sensor (
PX-SB1
). Refer to the instruction manual enclosed with auxiliary sen-
sor (
PX-SB1
).
After sensitivity adjustment, fit the adjustment panel cover using the accessory adjuster
screwdriver. The tightening torque should be 0.5N
m or less.
㧙
㧙
Place an object to be detected at the required sensing position, and
turn the sensitivity adjuster gradually clockwise and mark the point
where the indicator turns on (Note 1).
ԝ
㧙
Ԝ
After all the adjustments are made, the operator must confirm that the
sensing area is set correctly by observing the detection of the object as
it approaches from different directions.
Carry out steps

and
ԛ
for each of the areas OUT 2, OUT 1, ad-
jacent left / right OUT 1 and auxiliary sensors (if they are connected).
ԛ
Ԛ
ԙ
Turn the sensitivity adjuster fully counterclockwise to the minimum
sensing range position.
Ԙ
Set the output operation mode switch to the L. ON mode position (Light-ON).
Step Sensitivity adjustment
Operation
Remove the object and turn the sensitivity adjuster further clockwise.
Find out the point where the indicator turns on again. Make sure that
the difference between point and is 1 div., or more, on the scale.
Then, set the sensitivity adjuster at point .

For
PX-24ES
and
PX-23ES
, set the ex-
ternal control function selection switch
in the adjustment panel to 'INT.' side.
Sensing area of
PX-26
main
sensor is not selectable.
PX-24ES
and

allow
sensing area selection with ex-
ternal signal, too.

Connection of
auxiliary sensor
(Note 1)
If you expect to use the optional auxili-
ary sensors (
PX-SB1
), connect them
to the main sensor and install them.
(Note 2)
Refer to the instruction manual
enclosed with auxiliary sensor
(
PX-SB1
).
Ԙ
Mounting and
preparation
Mount the main sensor at the required lo-
cation. Open the adjustment panel cover.
