Start-up
ACT 600 – 5000 15 – EN
5.2 First start-up
This procedure should be followed on first start-up, after periods of extended shutdown or following
maintenance procedures.Qualified personnel must perform the start-up.
Sequence of operations (refer to paragraph 7.1 Control Panel).
 Ensure that all the steps of the “Installation” chapter have been observed.
 Ensure that the connection to the compressed air system is correct and that the piping is suitably fixed
and supported.
 Ensure that the condensate drain pipe is properly fastened and connected to a collection system or
container.
 Ensure that the by-pass system (if installed) is closed and the dryer is isolated.
 Ensure that the manual valve of the condensate drain circuit is open.
 Remove any packaging and other material which could obstruct the area around the dryer.
 Activate the mains switch.
 Turn on the main switch - pos. 1 on the control panel.
 The electronic instrument DMC24 shows
.
 If the alarm led flashes
and display DMC24 shows and the electrical power phases
are not correctly connected. Change two of the three phases on the main power supply (see
paragraph 4.8)
 Wait at least two hours before starting the dryer (compressor crankcase heater must heat the oil of the
compressor).
 Ensure the cooling water flow and temperature is adequate (Water-Cooled).
 Press key
for at least 2 seconds to start the dryer: if the compressor has been shut down for enough
time, it will start up immediately; otherwise the display will show the countdown of the seconds before the
compressor starts up again, and the led
flashes (max delay 5 minutes).
 Ensure the consumption matches with the values of the data plate.
 Check the rotation direction of the fan – wait for its first interventions (Air-Cooled).
 Allow the dryer temperature to stabilise at the pre-set value.
 Slowly open the air inlet valve.
 Slowly open the air outlet valve.
 Slowly close the central by-pass valve of the system (if installed).
 Check the piping for air leakage.
 Ensure the drain is regularly cycling - wait for its first interventions.
CAUTION:
ATTENTION SHOULD BE PAID ON THE ROTATING DIRECTION OF THE COMPRESSOR !
The rotating direction of the compressor in this machine is cheched out by a Reverse Phase
Protector (RPP).
When this protection trips, the DMC24 is engaged (the alarm led flashes
and the DMC24
display shows
and ). If the compressor does not run, the rotating direction must be
changed by swapping two phases. These changes have to be done only by a qualified electrician.
DO NOT BY PASS RPP PROTECTION: BY OPERATING THE MACHINE IN WRONG
ROTATING DIRECTION, THE COMPRESSOR WILL FAIL IMMEDIATELY AND THE
WARRANTY WILL BE VOIDED.
