FOREwORD
The user should appoint a qualified person for operation
and maintenance of the machine.
He should properly train all operators, so that they are
acquainted with all needed measures to prevent 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 Organization.
CHECKS bEFORE START
Before starting the machine, ensure that :
– the electrical system complies with voltage and
power of the machine and that wires are of suitable
section;
– the machine is connected to earth and protected
from any short circuits;
– the line knife switch is installed near the machine;
– the machine oil level is correct. When the machine is
still and without pressure in the chamber, oil should
exceed the visual check pilot light. If the level is
insufficient, fill it up with suitable oil and of the same
type as the one used;
– the machine is connected to the compressed air
system.
OpERATION MODES (bLADE vERSION)
To meet the users’ requirements, Mattei compressors
have been designed to work in three main operating
modes: Continuous, Automatic and Modulation.
The factory mode is AUTOMATIC. To modify the preset
mode, see Page 16 of MAESTRO
XB
User Manual.
An overview of these two options is given below.
CONTINUOUS MODE (CONT) AND MODULATION
In this mode, the compressor delivers air within a clearly
defined pressure range; maximum and minimum values
are factory-set by Mattei though they can be customised
using the programming functions in the [User] menu.
When pressure reaches the maximum value (Pmax)
the compressor 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.
F
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.
