Subject to change without notice
LED indicator/fault pattern
Yellow LED flashes; if Health is
present then take note of the
corresponding output signal; if
Alarm is present then take note
of the corresponding output
signal
Yellow LED lights up, no object
in the path of the beam
The sensor must be disposed of according to the applicable country-specific regula‐
tions. Efforts should be made during the disposal process to recycle the constituent
materials (particularly precious metals).
NOTE
Disposal of batteries, electric and electronic devices
• According to international directives, batteries, accumulators and electrical or
electronic devices must not be disposed of in general waste.
•
The owner is obliged by law to return this devices at the end of their life to the
respective public collection points.
•
WEEE: This symbol on the product, its package or in this document,
indicates that a product is subject to these regulations.
SICK sensors are maintenance-free.
We recommend doing the following regularly:
• Clean the external lens surfaces
• Check the screw connections and plug-in connections
No modifications may be made to devices.
Subject to change without notice. Specified product properties and technical data are
not written guarantees.
DISASSEMBLY AND DISPOSAL
Cause
Sensor is still ready for oper‐
ation, but the operating con‐
ditions are not ideal/addition‐
ally with health output: power
supply interrupted
The beam of light of a pho‐
toelectric through-beam sen‐
sor hits the receiver of
another (neighboring) photo‐
electric through-beam sensor
Measures
Check the operating condi‐
tions: Fully align the beam
of light (light spot) with the
receiver. / Clean the optical
surfaces / If the potentiome‐
ter is set to the max. sen‐
sitivity: Reduce the distance
between the sender and the
receiver chapter 7.2 / Check
sensing range and adjust
if necessary, see figures in
chapter 7.2. / With health
output: Check the voltage sup‐
ply, check all electrical con‐
nections (cables and plug con‐
nections).
Swap the sender and receiver
arrangement at every sec‐
ond through-beam photoelec‐
tric sensor and ensure that
there is sufficient distance
between the through-beam
photoelectric sensors, see
figure 1.
