Mounting & Installation
Mounting & Installation
1
Position the sensor pointing at the target object.
2
Align by moving sensor horizontally and vertically until the output changes when the
target object is present (refer to Output Logic table).
3
Fasten the sensor securely using the enclosed locking nuts and/or a mounting bracket.
Avoid acute angles on cable close to sensor.
Adjustments
General
Sensitivity and output mode can be adjusted using the potentiometers or with the IO-Link.
The IO-Link allows the user to setup and read several functions and parameters. Please refer to
“SMP and PC connection” on the following page.
Output Mode Selection
The output mode can be selected via an integral light/dark switch, or via IO-Link. Refer to Output
Logic table for output mode reference. Note that the NPN output is closed when IO-Link/push-
pull is low and the yellow output LED is off.
Light Operated (N.O.)
Enables the output to be active
when there is an object present.
Turn switch to full clockwise
position, or set:
- Overwrite light operated =
true
- Light operated =
true
in the Parameters tab.
Dark Operated (N.C.)
Enables the output to be inactive
when there is an object present.
Turn switch to full counter
clockwise position, or set:
- Overwrite light operated =
true
- Light operated =
false
in the Parameters tab.

Sensitivity Adjustment
Maximum sensitivity can be used for most applications and is advised for applications with
contaminated environments. The sensitivity can be adjusted on the potentiometer (factory
default active) or via IO-Link.
Sensitivity adjustment may be required in applications where objects to be detected have
highly reflective, dark or textured surfaces and/or applications where a background is present.
This can be achieved manually or via IO-Link.
For sensitivity adjustment, proceed with the following steps:
1
Start with the sensitivity at minimum by turning the potentiometer to full counter
clockwise position.
2
Select target object with the smallest dimensions and least reflective surface.
3
Place target object in front of sensor.
4
Via potentiometer:
Increase the sensitivity by turning the potentiometer clockwise
until the target object is detected and the output status changes (Position 1)
Via IO-Link:
Press the System Command Teach gain button in the parameter tab.
This will adjust and determinate the best sensitivity level, independently of the
predefined gain.
If the output has not changed, attempt to move sensor closer to target object and
repeat procedure.
5
If there is a background proceed to step 7. If there is no background proceed to
step 6.
6
Turn the potentiometer clockwise to a position midway between Position 1 and
maximum clockwise position.
7
Remove target object. If the output changes, proceed to step 8. If the output has not
changed, a background is detected. Proceed to step 10
8
Turn the potentiometer clockwise until the output status changed (Position 2). A
background is now detected.
9
Turn the potentiometer counter clockwise to a position midway between Position 1
and Position 2.
10
If the background is still detected and the output has not changed, attempt to angle
the sensor in relation to the plane of the background. Then repeat procedure from
step 1.
