The functional specifications refer to a mild steel reflector defined by ifm at
maximum range and with an edge length of 300 mm. The minimum size of
the reflector depends on the size of the object.
With ultrasonic retro-reflective sensors adhere to the minimum distances to
the reflector (→ Technical data sheet).
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.

6 Settings
The unit and the parameters are set via the IO-Link interface (→ 6.1) or the
teach button (→ 6.2).
6.1 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.
6.2 Teach button
6.2.1 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.
6.2.2 Adjust the unit to the reflector
The sensor is operational once the reflector has been aligned to it.
► Start programming mode (→ 6.2.1).
► Align the reflector to the unit (fig. 1).
► Press the teach button for 1 s.
> Yellow status LEDs 1/2 flash (2.5 Hz), adjustment is completed.
6.2.3 Invert output response
► Press the teach button for > 6 s.
> Yellow status LEDs 1/2 flash (> 10 Hz).
► Output function is inverted.

6.2.4 Restore factory setting
► Align the unit so that no echo is received.
> Green echo LED off.
► Start programming mode (→ 6.2.1).
► Press the teach button for 1 s.
> Yellow status LEDs 1/2 flash briefly (4 Hz), factory setting is restored.When the
barrier is interrupted by an object, the following output signals are provided:

7 Operation
Check whether the unit operates correctly. Bring about a sensor response by
taking suitable measures.
Display by LEDs (independent of the programmed output configuration):
Status LED 1/2 yellow ON Switching output is active.
Echo LED green ON Echo is received.
Echo LED green flashing Short circuit at the output.
Reflector is outside the detection zone.
> Echo LED green OFF.
> With NO function = switching output active. With NC function = switching
output inactive.
