TROUBLE
Luminous switch / Display
of the control panel OFF.
The compressor doesn't
start.
The fan doesn't work.
Condensate drain absent
(no water nor air even
after pushing TEST
button).
Air flows continuously
through the condensate
drainage.
Water in the pipes
downstream the dryer.
The temperature on the
control panel display is
higher than the nominal
value.
Cod. 710.0138.20.00 Rev1A – 10.2010
Troubleshooting and eventual control and/or maintenance operations must be
performed by qualified personnel.
For maintaining the refrigerating circuit of the machine, contact a refrigeration engineer.
POSSIBLE CAUSE AND REMEDY
1. Check if the line is electrically powered.
2. Check cabling.
3. Check the electronic control board; if the trouble persists, replace it.
1. Check cabling and control.
2. Activation of compressor's internal thermal protection; wait one hour and check
again. If the fault persists: stop dryer and call a refrigeration engineer.
3. Check the compressor's electrical components.
4. Short circuit in the compressor. Replace it.
1. Check the protection fuse (if present), and in case replace it.
2. Check cabling.
3. Check the electronic control board; if the trouble persists, replace it.
4. Short circuit in the fan. Replace it.
5.
Mod. 400 ÷ 600: Defective or burned out fan pressure switch: stop dryer and contact a
refrigeration engineer.
1. Check cabling.
2. Pre-filter of the drainage system dirty, clean it.
3. The coil of the drainage solenoid vale is burned out, replace it.
4. Drainage solenoid valve clogged/jammed, clean or replace it. (pic.4)
5. Check the electronic card, if the trouble persists, replace it.
6. The temperature on the display of the control panel is lower then the nominal
value, call a refrigeration engineer.
1. Drainage solenoid valve jammed, clean or replace it.
2. Verify the condensate drainage times.
3. Check the control. If the trouble persists, replace it.
1. The dryer is off; turn it on.
2. Close by-pass (if present).
3. Condensate drainage absent; see specific section.
4. The temperature on the control panel display is higher than the nominal value; see
specific section.
1.
Check if the compressed air inlet/outlet is connected properly.
2.
The compressor doesn't start; see specific section.
3.
The fan doesn't turn; see specific section.
4.
The flow rate and/or temperature of the air entering the dryer are higher than the
nominal values; restore the nominal conditions.
5.
The ambient temperature is higher than the nominal values; restore the nominal
conditions.
6.
The condenser is dirty; clean it.
7.
Condensate drain absent (no water nor air); see specific section.
8.
Check if the temperature control probe in the evaporator is positioned improperly or
faulty.
9.
Gas leakage in the refrigerating circuit: stop dryer and call a refrigeration engineer.
10. Check cabling.
11. Mod.400 ÷ 600: Defective or burned out fan pressure switch, contact a refrigeration
engineer.
