CAUTION!
Please observe the direction of rotation of the fix speed compressors!
In this system, the direction of rotation of the fix speed compressors is supervised by a reverse-
phase protector (RPP).
When this guard is triggered, the DMC50 goes into alarm mode (the status bar flashes red and shows
alarm n.5 “Compressor Protection”). In the event that the compressor does not run, the direction of rotation
must be changed by interchanging two phases. These modifications must only be carried out by a qualified
electrician.
Do not by-pass the RPP protector: If the device is operated with the incorrect direction of rotation,
the compressor will fail immediately. This will void the guarantee.

Start-up and shut down
During short-term shut down (max. two to three days), it is advisable to leave the dryer and the control
panel connected to the supply current circuit. Otherwise, it would be necessary at a restart of the dryer to
wait two hours, until the oil in the compressor has reached the specified operating temperature.
Start-up (refer to section 10.1 Control Panel)
•
Check the condenser for cleanliness (Air-Cooled).
•
Ensure the fan filter of electrical panel is clean.
•
Ensure the cooling water flow and temperature is adequate (Water-Cooled).
•
The display of electronic controller shows
(STANDBY).
•
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.
•
Wait few minutes; verify that the DewPoint temperature displayed on electronic controller is correct and that the
condensate is regularly drained.
•
Switch on the air compressor.
Shut down (refer to section 10.1 Control Panel)
•
Check that the DewPoint temperature displayed on electronic controller is within range.
•
Shut down the air compressor.
•
Keep pressed the button
at least 3 seconds, the dryer stops and the display shows
(STANDBY).
Dryer remote control ON-OFF
•
See instructions on section 10.15.11
Note!
A dew point between 0°C and +10°C (34°F and 50°F) displayed on the electronic controller is considered
to be correct according to the possible operating conditions (flow rate, air inlet temperature, ambient
temperature etc.).
The electronic controller DMC50 adjusts compressor and fan(s) speed according to thermal load applied to the dryer.
At very low or no load conditions, compressor is switched ON and OFF by the DMC50 to keep the temperature of the
heat exchanger cold, allowing a consistent additional energy saving.
The dryer must remain
(ON) during the full usage period of the compressed air, even if the air compressor
works intermittently.
