15.8 Compressor Settings and
Information Button
If the slave compressor is compatible and
communicating with the master, compressor information
can be obtained and configured by touching the
compressor button. Depending on the slave controller
type, some data are read out by the slave while others
have to be set manually. Therefore, an appropriate
button is provided instead of a simple indication.
Note
Correct compressor settings must be ensured in order
for the BLS to operate faultlessly.
