MAESTRO
xs
is a programmable control unit
which adapts compressor operation to the
specific requirements of the air line it is con-
nected to. It features various programming
levels and performs operating and fault con-
trols and analysis.
Advanced programming and analysis levels
are protected by digital codes to prevent unin-
tentional access.
Maestro xs also contains a memory which
saves settings and operating data even if the
compressor is disconnected from the power
supply or switches off due to a power cut.
