Start-up
9.1
Preliminary operation
Note!
Exceeding of the operating parameters!
Ensure that the operating parameters comply with the nominal values indicated on the name plate of the
dryer (voltage, frequency, air pressure, air temperature, ambient temperature etc.).
This dryer has been thoroughly tested, packaged and inspected prior to shipment. Nevertheless, the unit could be
damaged during transportation, check the integrity of the dryer during first start-up and monitor operation during the
first hours of operation.
The initial start-up must be carried out by qualified personnel.
During the installation and operation of this device, all national regulations regarding electronics and any
other federal and state ordinances, as well as local provisions, need to be adhered to.
The operator and the user must ensure that the dryer is not operated without panels.
9.2
First start-up
The method below should be applied during the first start-up, after longer downtimes or subsequent to
maintenance works.
The start-up must be carried out by certified skilled personnel.
Sequence of operations (refer to section 10.1 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.
•
Wait about 45 seconds the initialization of the electronic controller DMC50.
•
Select the desired language and the current date and time (see sections 10.15.15 and 10.15.16)
•
Wait at least two hours before starting the dryer (compressor crankcase heater must heat the oil of the compressor).
•
Keep pressed the button
at least 3 seconds, the dryer starts and the display shows
(ON).
•
If the temperature shown on the display is sufficiently high, verify that the refrigerating compressor starts within a few
minutes.
NOTE!
– With low temperatures, the refrigerating compressor will remain OFF.
•
NOTE!
–
if the dryer doesn’t start and the DMC50 shows the alarm n.5 (Compressor Protection), power
phases are not connected properly.
Change two of the three phases at the supply mains (see Section 7.6).
•
Ensure the cooling water flow and temperature is adequate (Water-Cooled).
•
Ensure the effective operation of the fan, watching its speed percentage on the display (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.
