Make sure that the cables and edges are located away from
sources of electromagnetic interference.
`
Ensure that the emitter and receiver are correctly aligned
and remain so during door closure (e.g. that vibrations do
not cause edges to become misaligned).

Important:
Whenever a parameter is changed, the system must be restarted.
If a problem persists, please contact your local CEDES representative. Visit www.cedes.com for contact data.
15. Maintenance
Although the GridScan/Pro SI does not need regular
maintenance, a periodic functional check is strongly
recommended:
Make sure the optical elements are clear of dirt and
dust. If necessary, clean the front surface with a soft
towel.
Make sure the edges are securely fastened.
Check the mounting position, cable routing and
connection of the sensor.
NOTICE
Damage to the optical elements
Never use any solvents, cleaners or mechanically
abrasive towels or high-pressure water to clean
the sensor.
Avoid scratching the optical elements while
cleaning.
16. Disposal
The GridScan/Pro SI should only be replaced if a similar
protection device is installed. Disposal should be done
using the most up-to-date recycling technology according
to local regulations and laws. There are no harmful materials
used in the design and manufacture of the sensor. Traces
of such dangerous materials may be found in the electronic
components but not in quantities that are harmful.
