Description of the Machine
The controller manages the dryer operation by monitoring the dew point temperature that allows the
system to run correctly.
The operating limits for such a parameter are as follows:
✔
The dew point temperature > 0°C;
✔
The dew point temperature < 6°C with Ambient Temperature ≤ 25°C;
✔
The dew point temperature < T.amb. – ƒ ambient with Ambient Temperature > 25∞C.
MATTEI sets the ƒ ambient value.
If the dew point drops below 0°C, the controller will indicate the faulty condition [Ice Alarm] while the
dryer compressor is kept active throughout the time corresponding to the parameter [Low Temperature
Delay Time].
Once this time has elapsed, the dryer compressor is stopped so to prevent any ice from forming.
As soon as the temperature rises again above 0°C, the dryer compressor is re-started and the fault
warning is automatically turned off.
Should the dew point temperature rise above the upper limit, the controller will indicate the fault condi-
tion [ALARM High Dew Point] for the time that corresponds to the parameter [High Temperature Delay
Time].
When the set time has elapsed, the Alarm warning will stay on.
As soon as the temperature falls again within the above-mentioned operating interval, the fault warning
will be automatically turned off
NOTE
:
The user can request Ing. ENEA MATTEI that the fault in the dryer corresponds to a machine BLOCK.
NOTE
:
The design of the dryer prevents condensate from accumulating and ice from forming inside it.
In case of any failure in the dryer, by-passing the device is possible by disconnecting the hose linking it
to the air radiator and connecting it directly to the delivery side. All joints installed are equivalent.
