15. COMMISSIONING
Make sure all transport stabilizers were
removed.
Check that all compressed air hose
connections are secure.
Check to ensure the power cord is properly
connected to the mains.
Check to ensure the outlet valve is in the OFF
position.
16. SWITCHING 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 introductory screen:
PRESS “ON” on the DRYER and WAIT 5
minutes.
Press and hold the ON/OFF button on the
dryer panel for 1 second and wait 5
minutes. 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 for 5 minutes, this time is shown in the
bottom row of 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.
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
TOT.HOURS – total time the compressor has
been energised
HOURS RUN - air pumps operating hours
TIME-TO-GO MN – time to the next
maintenance / service work
SERVICE – number of completed service calls
(2,000 h)
