and one of the two messages will be displayed
when the display shows
“Load run”
the intake valve is open and the machine operates
at full load (produces the nominal capacity of compressed air).
During functioning, delivery pressure increases; once the preset maximum line pressure
threshold value has been reached, the control system sets the compressor to idling
by closing the intake valve
“Unload run”
. when the pressure drops below the preset
minimum threshold value, the intake valve opens again and the machine restarts
functioning at full load.
During unload run, two cases may arise:
a)
Setting of AuTOMATIC functioning (see paragraph 4.2.3):
The compressor outputs this message followed by a countdown.
At the end of the countdown, the compressor switches off, changing to”Stand-by
auto start”, status, ready to restart in the case of a request for air.
b)
Setting of CONTIN. functioning (see paragraph 4.2.3):
The compressor outputs the “unload run message, the machine never stops,
always remaining available to restart production of compressed air immediately
in the case of any request.
