This device is not to be used for Personnel Protection in Machine
Guarding Safety applications. This device does not include the self-
checking redundant circuitry necessary to allow its use in personnel
machine guarding stand-alone safety applications.

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.
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
“SMRR and PC connection” on the following page.
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.C.) Enables the output to be inactive
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.O.) Enables the output to be active
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.

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, or by setting the Gain value to 255.
2 Select target object with the smallest dimensions and most translucent surface.
3
Place target object between the sensor and retro-reflector. If the output status
changes, adjustment is not required. If the output has not changed proceed to step
4.
4
Decrease the sensitivity by turning the potentiometer counter clockwise or decrease
the Gain value to a lower value until the output changes.
If the output has not changed, attempt to move the sensor and retro-reflector further
apart or angle the sensor/retro-reflector. Then repeat procedure from step 1.
Alternatively, remove any object and press teach-gain button using IO-link.
5 Remove target object. Check the output status has changed.
