The dryer doesn’t drain
the condensate.
The condensate drain service valve is closed - open it.
The condensate drain strainer is clogged - remove and clean it.
The drain solenoid valve is jammed - remove and clean it.
Verify the electric wiring.
The coil of the condensate drain solenoid valve burned out - replace it.
The DewPoint is too low - the condensate is frozen - see specific point.
The DMC15 electronic controller is faulty - replace it.
The dryer continuously
drains condensate.
The drain solenoid valve is jammed - remove and clean it.
Try to remove the electric connector on the solenoid valve - if drain stops verify the
electric wiring or the electronic instrument is faulty - replace it.
Water within the line.
The dryer doesn't start - see specific point.
Where installed - Untreated air flows through the by-pass unit - close the by-pass.
The dryer doesn’t drain the condensate - see specific point.
DewPoint too high - see specific point.
Where installed - The PA
high-pressure switch has
been activated.
Check which of the following has caused the activation :
1. The ambient temperature is too high or the room aeration is insufficient - provide
proper ventilation (Air-Cooled).
2. The condenser is dirty - clean it (Air-Cooled).
3. The condenser fan doesn’t work - see specific point (Air-Cooled).
Reset the pressure-switch pressing the button on the controller itself - verify the
dryer for correct operation.
The PA pressure switch is faulty - contact a refrigeration engineer to replace it.
Where installed - The PB
low-pressure switch has
been activated.
There is a leak in the refrigerating fluid circuit - contact a refrigeration engineer.
The pressure switch restores automatically when normal conditions are restored -
check the proper operation of the dryer.
Where installed - The TS
safety thermo-switch has
been activated.
Check which of the following has caused the activation :
1. Eccessive thermal load – restore the standard operating conditions.
2. The inlet air is too hot - restore the nominal conditions.
3. The ambient temperature is too high or the room aeration is insufficient - provide
proper ventilation.
4. The condenser unit is dirty - clean it.
5. The fan doesn’t work - see specific point.
6. There is a leak in the refrigerating fluid circuit - contact a refrigeration engineer.
Reset the thermo-switch by pressing the button on the thermo-switch itself – verify
the correct operation of the dryer.
The TS thermo-switch is faulty - replace it.
DMC15- The first and the
last LED of the display of
electronic instrument blink
simultaneously.
Verify the electric wiring of (T1) DewPoint probe.
The (T1) DewPoint probe is faulty - replace it.
The DMC15 electronic controller is faulty - replace it.
DMC15- The yellow
LED of the electronic
controller is flashing
continuously.
AMD 3-32 - Verify the electric wiring of (T2) fan control probe.
AMD 3-32 - The (T2) fan control probe is faulty - replace it.
AMD 43-168 –
Verify the electric wiring of resistance on terminal 1 and 2.
The DMC15 electronic controller is faulty - replace it.
DMC15- The first LED of
the display of electronic
instrument is flashing
continuously.
DewPoint too low - see specific point.
The (T1) DewPoint probe is faulty - replace it.
The DMC15 electronic controller is faulty - replace it.
DMC15-
The last LED of
the display of electronic
instrument is flashing
continuously.
DewPoint too high - see specific point.
The (T1) DewPoint probe is faulty - replace it.
The DMC15 electronic controller is faulty - replace it.
