Safety devices
EMERGENCY PUSHBUTTON
The machine stops immediately when the button is
pressed, while skipping the regular stop sequence
provided by the STOP button.
This button is to be used also in an emergency situation.
Frequent stops of the compressor by means of this
button may damage its operation.
WARNING !!!
Please refer to the Manual of the “MAESTRO
XB
”
Control attached to this manual for the
detailed description of keys, programming,
and all of its functions.
SAFETY VALVE
A safety valve protects the compressor in case of air
overpressure inside the chamber, while limiting the
value to its own setting limit. The safety valve is set on
12 bar for L, H and BLADE i version of compressors and
15 bar for HH versions.
SERVOVALVE
Besides the operating pressure control perfomed by
MAESTRO
XB
, compressors of BLADE 15÷22 Series, keep
the modulation and o load functions by means of a
servovalve. This servovalve limits the maximum operating
pressure, during the CONTINUOUS mode operation by
acting on the intake valve, which closes as the internal
pressure increases. The maximum operating pressure is
set at its optimal value during the nal inspection and
DOES NOT require any further adjustments.

Servo valves 8 bar 10 bar 13 bar
NOTE
Compressor operation depends on the set
values; it is suggested to ask for modication
of settings only in case of real need and with
knowledge. Only skilled personnel should
make the setting.
WARNING !!!
DO NOT set the servovalve at HIGHER values
than those used by the manufacturer, Ing.
Enea Mattei S.p.A. In fact, if the machine
works at higher pressures it absorbs greater
power. This could lead to overheating and the
stopping of the machine.
