the dryer itself cools down and the
internal pressure is balanced.
The dryer begins cooling the heat exchanger.
Wait 5 minutes, the period counts down on the
display (16). Once the period is over, the
display indicates that the compressor start-up
process may begin.

Press the "START” button (18) on the
switchboard.
The display shows:
HOURS RUN: operating hours
PRESSURE: current pressure
TEMP_IN: internal temperature (only for
enclosed compressors)
Note: TEMP_IN reads “N/A” for compressor
models with no cover
TEMP_OUT: ambient temperature around the
compressor
The first air pump automatically turns on and
the other air pumps then sequentially turn on.
The pressure sensor monitors the pressure in
the air tank.
The air pumps operate in automatic mode,
and are switched on and off (see the section
on working pressures in the Technical Data
chapter) by the controller depending on the
compressed air usage. The compressors
sequentially turn off once the switching
pressure is reached.
The motors may be shut down by pressing the
STOP button (18), after which the display
returns to the start screen.
Note:
The START button is preset to
"RETENTIVITY=ON", which means that if the
compressor has been activated once using
the START button, the system remembers this
action and there is no need to press the
START button to start up the compressor in
the event of a power loss or if the compressor
has been turned off.
NORMAL OPERATION
Air pumps operate in automatic mode and are
switched on and off based on the demand for
compressed air. When the pressure in the air
tank drops to the switching pressure, the
compressors automatically switch on in a
sequence. This ensures that the required
pressure is delivered to the air tank in the
shortest possible time.
Two screens are shown on the display during
the normal operation of the equipment:

Motors are on
PRESSURE: current working pressure
TEMP_OUT - ambient temperature around
the compressor
TEMP_IN
- temperature inside the
compressor cover
- Text “N/A” - displayed for
models with no cover
COMPRESSOR ON – all air pumps on / off
HOURS RUN - operating hours
TIME-TO-GO MN - time to the next
maintenance/service work (in hours).

Motors are switched off
PRESSURE: current working pressure
STANDBY MODE – all air pumps are
switched off
HOURS RUN - operating hours
TIME-TO-GO MN - time to the next
maintenance/service work (in hours).
