Maintenance
Cleaning other optical surfaces:
¾
If an external reading pulse generator and/or object-height detection sensors are used
(e. g. photoelectric reflex switches), make sure to clean the relevant optical surfaces
(
).
Contamination on these surfaces can cause switching errors.
Incremental encoder
If an incremental encoder is used, check the correct position on the conveyor.
¾
Ensure that the incremental encoder always contact the conveyor so that the friction
wheel turns without slipping.
7.2
Maintenance
The CLV does not require any maintenance except the described cleaning measures.
Its self-monitoring functions ensure fault-free operation over long periods of time.
The CLV indicates any faults or malfunctions by outputting coded system and error messa-
ges (e. g. "CLV SYS-Failure: 081") via its terminal interface. The messages are displayed in
the "CLV-Setup" program window in the fourth field from the left on the bottom, in the status
line (see also
Chapter 8.3 Error messages, Page 8-2
). CLV-Setup logs the messages in a
file.
7.3
Disposal
Irreparable devices or devices that are no longer required must be disposed of in an
environmentally-friendly manner:
1.
Always observe the applicable national waste disposal regulations.
2.
Remove the CLV housing.
3.
Remove the electronic modules.
4.
Remove the glass panel from the reading window and send it to be recycled.
5.
Send the chassis and cover (aluminium) to be recycled.
6.
Send the electronic modules for disposal as problem waste.
At present, SICK AG does not accept any unusable or irreparable devices.
