Maintenance
Cleaning other optical surfaces:
If an external reading pulse generator with a sensor (e. g. photoelectric reflex switch) is
used, make sure to clean the relevant optical surfaces (
). Contamination on
these surfaces can cause switching errors.
If the reading pulse is generated by reflector polling, make sure to clean the surface of
the reflector.

Maintenance
The CLV does not require any maintenance except the described cleaning measures.
Its self-monitoring function ensures fault-free operation over long periods of time.
Any faults or malfunctions are displayed as error messages via the terminal interface. If they
are plain text, they can be displayed on the PC screen in the extended mode of the Terminal
Emulator in the CLV Setup program. Additional errors are displayed as number combinations
in the fourth field from the left on the bottom, in the status line (
) .
