Troubleshooting
Meaning
Network operation:
the CLV is waiting for polls by
the CLX 200 network
controller.
The CLV cannot operate the
oscillating mirror or cannot
initialize the mirror.
Data transmission error
between a slave and the
master.
During the master timeout,
the master receives more or
fewer reading results from
the slaves than expected
from the number of slaves
that the master has entered.
After selection of the
master/slave function,
individual parameter values,
which are not compatible
with the automatic settings
defined for this function by
the CLV, were changed
subsequently
