OPERATION
In case of emergency, disconnect
the compressor from the mains
(turn off the main switch).
The compressor air pump has
hot surfaces. Burns may result if
contact is made.
During prolonged operation of
the compressor, the temperature
may increase to over 40°C. At
this point the cooling fan
automatically switches on. The
fans switch off automatically
once the space is cooled to
below 32°C.
Automatic start. The compressor
automatically switches on when
pressure in the air tank drops to
the pressure switch’s lower limit
level.
The
compressor
automatically switches off after
reaching the pressure switch’s
upper limit level.
10. TURNING THE COMPRESSOR ON
(Fig. 1 - 3)
Rotate the main switch Q10 on the
compressor’s switchboard to the “I”
position, the green POWER ON indicator
turns on and the 5 minute interval begins
to count down; this interval is needed to
bring the ED072 dryer up to standard
operating parameters.
The control module display shows the
following screen:
Press and hold the ON/OFF button on the
dryer panel for 1 second. The dryer
motors then gradually start
The dryer may be shut off by pressing and
holding the ON/OFF button again for 1
second. The dryer motors then switch off
to ensure the space inside the dryer itself
cools down and the internal pressure
balances.
The dryer begins cooling the heat exchanger.
Wait 5 minutes, the period counts down on the
display.
Once this period expires, the compressor
motors activate automatically one by one.
The first air pump automatically turns on and
the other two air pumps then gradually turn
on. The pressure switch 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
compressed air usage. The compressor
motors gradually turn off once the switching
pressure is reached.
NORMAL OPERATION
Air pumps operate in automatic mode and are
switched on and off based on demand for
compressed air. When the pressure in the air
tank drops to the switching pressure, the air
pumps automatically switch on in a sequence.
This ensures that the required pressure is
delivered to the air tank in the shortest
possible time.
The display shows the normal mode screen
during normal operation of the equipment:
MOTORS ON or MOTORS OFF depending on
the current status of the motors.
