16. SWITCHING ON THE COMPRESSOR
•
Turn the main switch (19) into the “I”
position
on the compressor
switchboard (Fig. 2). The white
indicator P1 (17) lights up, the
compressor is in STOP mode and the
display (16) on the switchboard door
shows the following message:
The first row shows the SW version number
RUN HOURS: operating hours average value
PRESSURE: current pressure
TEMP_OUT: outdoor temperature
•
Press the "START” button (18) on the switchboard. (Fig. 2)
The display shows:
PRESSURE: pressure in the system
TEMP_OUT: ambient temperature around
the compressor
The third row shows any active blowdown.
STAND BY MODE or RUN MODE
RUN HOURS: operating hours average
Time-To-Go MTN : shows the time
remaining until compressor maintenance is
required
Pressing START activates the compressor air
pumps in sets of three based on the load, see
Fig. 24.
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 chapter
Technical Data) 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 pre-set 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.
Screens are shown on the display during the
normal operation of the equipment:
