Safety notes
These photoelectric sensors may not be used
in applications where personal safety depends
on proper function of the devices (not designed
in accordance with EU Machinery Directive).
Read these operating instructions carefully
before putting the device into service.
Exempt Group according to
IEC 62471:2006-07.
DO NOT LOOK INTO THE LIGHT BEAM!
Danger of glare and irritation!
The sensor must be installed as to prevent a
direct line of eyesight to the light source, even
during operation.
The CE Marking confirms that our products
conform to the EC Directives 2004/108/EC
(EMC) and the EMC law.
In our EMC Laboratory, which is accredited by the DATech
for Testing of Electromagnetic Compatibility, proof has
been documented that these Balluff products meet the
EMC requirements of the harmonized standard
EN 60947-5-2.

Optical adjustment
This sensor is factory set for maximum sensitivity. This
setting may be changed.
CAUTION
Damage to the push button!
Sharp or pointed objects may damage the button.
Use only a blunt object or your fi nger to press the
button!
Setting sensitivity (static)
1. Align the sensor with the object.
2. Press the button approx. 3 s until both LEDs are
flashing synchronously.
3. Remove the object from the detection range. For fixed
objects, leave the object in place.
4. Hold down the button for approx. 3 s.
– When the object is removed:
The green LED flashes briefly and then stays on.
The yellow LED is off. The sensor has read the
object and the background is reliably ignored. The
switchpoint is located between the object and the
background.
– For fixed objects:
The green LED flashes briefly and then stays on.
The yellow LED is on. Set the switchpoint so that it
lies between the object and the background with
minimal hysteresis.
5. Check for correct operation of the switchpoints.
Setting output function for light-switching/dark-
switching
The factory setting for the sensor is light-switching.
1. Press the button for approx. 13 s until only the green
LED is flashing.
2. Release the button: the green LED flashes.
3. While the green LED is flashing, each press of the
button toggles the output function. This is indicated by
the yellow LED.
4. To save the present output function: do not press the
button for at least 10 s.
To return to factory setting (max. range)
►
Perform the setup procedure with no object and
background in the beam path.

Function reserve
The function reserve is a unitless factor which indicates
how much more light reaches the receiver than is
necessary for function of the sensor.
The larger the factor, the more stable the sensor operates.
For applications in dirty surroundings, a greater function
reserve is needed than under laboratory conditions.
The maximum range of the sensor should therefore not
always be used.
