The functional specifications refer to a mild steel reflector defined by ifm, at
maximum range, with an edge length of 300 mm. The minimum size of the
reflector depends on the size of the object. For further information please
view "Basic information about installation and operation" → www.ifm.com.
When using ultrasonic reflective barriers, please observe the minimum
distances to the reflector → Technical data sheet!

8 Operation
►Check whether the unit operates correctly.
> Display by LEDs:
Green LED is lit The echo is received by the reflector.
Yellow LED on The object interrupts the ultrasonic reflective barrier, the output is
switched (output function NO).
Yellow LED on /
green LED off
Reflector is not detected (output function NO)
LED green flashes short circuit at the output.
The minimum distance between the "Proximity Switch Metal Enclosure"
and any "External uninsulated live part" shall be at least 12.7 mm.
