Self-test
After the CLV has been switched on, it performs a self-test before it is initialized with the
parameter set. The test can be called up explicitly at any time via CLV-Setup. During the self-
test, the CLV checks that its hardware components are functioning correctly. A final messa-
ge via the terminal interface provides information on the test result. The CLV does not output
a reading result during the test routine.
