Sound-absorbing surfaces have a negative effect on a reliable function.
►Consider the dead zone (→ Technical data sheet):
No object detection in the dead zone.
For units with metal housing (according to UL 508):
►Observe a minimum distance of 12.7 mm between the sensor and non-
insulated live parts.

5 Settings
The unit and the parameters are set via the IO-Link interface (→ 5.1) or the
teach button (→ 5.2).
5.1 IO-Link
This unit has an IO-Link communication interface which enables direct access to
process and diagnostic data. In addition it is possible to set the parameters of the
unit while it is in operation. Operation of the unit via an IO-Link interface requires
an IO-Link master.
With a PC, suitable IO-Link software and an IO-Link adapter cable communication
is possible when the system is not in operation.
The IODDs necessary for the configuration of the unit, detailed information about
process data structure, diagnostic information, parameter addresses and the
necessary information about the required IO-Link hardware and software can be
found at www.ifm.com.

5.2 Teach button
5.2.1 Start programming mode
►Press the teach button for 2 s...6 s.
> Yellow status LEDs 1/2 flash (1 Hz), the unit is in the programming mode.
If programming has not been completed successfully, the unit returns to the
previous setting.
5.2.2 Set output response
►Start programming mode (→ 5.2.1).
► Position the object in P1 (Fig. 1 or 2).
►Press the teach button for 1 s.
> Yellow status LEDs 1/2 flash (2.5 Hz), P1 setting is completed.
► Position the object in P2 (Fig. 1 or 2).
►Press the teach button for 1 s.
> Yellow status LEDs 1/2 flash briefly (4 Hz), P2 setting is completed.
5.2.3 Invert output response
►Press the teach button for > 6 s.
> Yellow status LEDs 1/2 flash (> 10 Hz).
> Yellow status LEDs 1/2 flash briefly (> 4 Hz).
> Output function is inverted.
5.2.4 Restore factory setting
►Align the unit so that no echo is received.
> Green echo LED off.
►Start programming mode (→ 5.2.1).
►Press the teach button for 1 s.
> Yellow status LEDs 1/2 flash briefly (4 Hz), factory setting is restored.
