wARNING !!!
If the failure cause cannot be solved, the
compressor will not start as the failure appears
to be still active and re-displays the intervention
request.
!
wARNING !!!
The rotation in the wrong direction can seriously
damage the compressor.
After completing all preliminary operations
before start-up, described in the previous
pages, this is the MAESTRO
XB
page displayed:
STARTING
Press the key to switch the compressor “on”
The compressor is started; it starts off load (intake valve
closed) and then goes on load after a pre-set time,
subsequent to the star-delta switching delay.
The compressor, from this moment on, delivers
compressed air according to the set operation mode
After start-up, the following page is displayed:
STOp
To stop the compressor, press key
The compressor is unloaded (decompressed) for a preset
time (basic programming).
After the motor has stopped the residual pressure inside
the compressor discharges completely in approximately
one minute. The following page shall be displayed:
The machine can be started according to the
previously described sequence, but it actually
starts only provided that the line pressure is
lower than the Pmin value set on the main
unit.
In case the line pressure is higher than Pmin, the
following page shall be displayed.

NOTE
MAESTRO
XB
has a control logic that prevents
an excessive number of consecutives starts.
This logic is cleared by the user ’s manual
intervention, if he/she acts directly by turning
off and on the machine manually.
!
WARNINg !!!
An excessive number of consecutive starts may
damage the main motor.
Operate manually only in case of real need and
wait for a reasonable amount of time before
restarting the machine.
The number of starts depends now on many
parameters,the rated power,the operation
cycle,the working pressure,and the ambient
temperature.
For any requirement,please contact MATTEI.
