SICK H18 - SureSense, Operating Instructions Manual

Page: 19 / 203

LED indicator/fault pattern Cause Measures
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 Sensor is still ready for opera‐
tion, but the operating condi‐
tions are not ideal/addition‐
ally with health output: power
supply interrupted Check the operating condi‐
tions: Fully align the beam of
light (light spot) with the
object / Clean the optical sur‐
faces / Check sensing range
and adjust if necessary, see
figures in
chapter 7 / With
health output: Check the volt‐
age supply, check all electrical
connections (cables and plug
connections).
Yellow LED lights up, no object
in the path of the beam Excessive background remis‐
sion Check changes to the back‐
ground. Reduce the sensitivity
of the sensor or use sensors
with background suppression
Object is in the path of the
beam, yellow LED does not
light up Sensitivity is set too low or dis‐
tance between the sensor and
the object is too long Increase the sensing range,
take note of the distance
between the sensor and the
background, see Figure
see
table 10, page 17
Object is in the path of the
beam, yellow LED does not
light up Remission capability of the
object is insufficient Increase the sensing range,
take note of the distance
between the sensor and the
background, see Figure
see
table 10, page 17
9 Disassembly and disposal
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, indi‐
cates that a product is subject to these regulations.
10 Maintenance
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.
