Foreword
The user is recommended to appoint a
quali
fi
ed person for the correct operation
and maintenance of the machine.
The user should properly train all opera-
tors so that they are acquainted with all the
steps aiming at preventing any accident or
injury to people.
All start and stop procedures as well as the
emergency ones should be known. They
should also be reviewed at regular intervals
with the operators.
The Use and Maintenance Manual should
always be easily available.
If lost or damaged, further copies can be
purchased from the Mattei Sales Organiza-
tion.
Checks before Start
Before starting the machine, ensure that:
the electrical system complies with both
voltage and power of the machine and
that cables are of the adequate section;
the machine is connected to earth and
protected from any short circuits;
the line disconnect switch is installed
near the machine;
the machine oil level is correct. When the
machine is off and there is no pressure
in the separator tank the sight glass
should be completely full of oil.d to the
compressed air system.
Operation Modes
Blade compressors are designed to opera-
te according to continuous and automatic
control logics.
The factory mode is AUTOMATIC. To mo-
dify the preset mode, see Page 16 of MAE-
STRO XB User Manual.
An overview of these two options is given
below.
Continuous (Cont)
In this mode, the compressor delivers air
within a clearly de
fi
ned pressure range;
maximum and minimum values are factory-
set by Mattei though they can be customi-
sed using the programming functions in
the [
User
] menu. When pressure reaches
the maximum value (
Pmax
) the compres-
sor is off-loaded (suction valve closed) and
decompressed in order to reduce power
consumption. As soon as a request for air
from the network reduces pressure to the
minimum value (
Pmin)
the compressor
loads again and resumes air delivery. The
compressor can be stopped at any time
by pressing the stop button: the stopping
procedure comprises a no-load run phase
which lasts for a set time during which the
compressor is decompressed.
Note
If the unit is enabled with a line pressure
greater than the set minimum pressure, the
compressor does not start but waits for the
pressure to fall below the minimum value.
