The operating modes are set via the control input (MF).
The switching output 1 (Q

/Q
–

) can be set by connecting
L+ to the control input (MF). Analog to this, the switching
output 2 (Q

–

) can be set by connecting M to the
control input (MF).
The Teach-in concept is explained using the example of
switching output 1 (Q

LED2 must be swapped in points

– Place the object at a switching distance near the sensor ;

The window with the switching point near the sensor and
far from it is stored permanently, and the sensor is ready to
operate. If the user tries to set the window width < 5 mm,
B1
(switching point with an object) is set. If a distance is
taught in the detection range of the sensor and a second
one is outside of the detection range, both LEDs blink for
3 seconds simultaneously fast (error display). The old
switching points are maintained.

The window is set symmetrically around the fixed reflector
with ± 8 % of the switching distance. If a distance is taught
in the detection range of the sensor and a second one is
outside of the detection range, both LEDs blink for 3
seconds simultaneously fast (error display). The old

Self-synchronization: Connect sensors via PIN 5 (max. 10
can be switched parallel). As a result, the “detection range”
is increased. When there is parallel operation of the
sensors, the installation distance sideways must be smaller
than 10 cm. A type of “grid operation” is achieved via the
synchronization.
– Switch of the power to the sensor (switch off the
operating voltage)
– connect M to the control input (MF), switch on the
operating voltage, keep M connected to the control
input (MF); LED2 blinks fast, and LED1 displays the state
of the switching output

– until both LEDs blink simultaneously (after approx. 3 s),
– remove M from the control input (MF); LED1 blinks fast,
and LED2 displays the operating mode; LED2 on =
Teach-in mode, LED2 off = synchronization mode
– while the LED1 blinks fast, there is a switch between
Teach-in and synchronization each time M is connected.
LED2 on = Teach-in mode; LED2 off = synchronization
mode.
If M is not connected for 10 s, the set output function is
adopted; the sensor is ready to operate. Do not connect
PIN 5 in RUN mode.

– Switch off the operating voltage
– connect M to the control input (MF), switch on the
operating voltage, keep M connected to the control
input (MF); LED2 blinks fast, and LED1 displays the state
of the switching output.
Both LEDs blink simultaneously after 3 s.
– until both LEDs display the switching state
(after approx. 13 s)
– remove M from the control input (MF).
The sensor has its factory setting.
Maintenance
SICK sensors do not require any maintenance. We recommend
that you clean the external lens surfaces and check the screw
connections and plug-in connections at regular inter vals.
