DRYPOINT® RA CT 20-500 NA
Prior to carrying out maintenance works at the dryer, switch it off and wait for at least 30 minutes.
Caution!
Hot surfaces!
During operation, several components can reach surface temperatures of more than 140°F (60°C).
There is the risk of burns.
All components concerned are installed inside of the closed housing. The housing must only be opened
by certified skilled personnel.
Some components can reach high temperatures during operation. Avoid any contact until the system or
the component has cooled down.
FAULT POSSIBLE
REASON
– SUGGESTED MEASURE
The display of DMC51
is not lit
Verify that the system is powered.
Verify the electric wiring.
If installed – HPS pressure switch has been activated – see specific point
RA CT 200-500 3phase - Blow of fuse (FU2 on the electric diagram) of the auxiliary
circuit - replace it and check the proper operation of the dryer.
RA CT 200-500 3phase – The remote control is OFF (see contact on terminals 1-2 on
electric diagram)
The compressor does
not work.
If ESS=YES (see section 8.12.7) – the Dew Point displayed on DMC51 is sufficiently
low, the led
is OFF, so the compressor is not active – wait that the temperature
becomes higher.
Activation of the compressor internal thermal protection – wait 30 minutes and then
retry.
Verify the electric wiring.
If installed – the KC relay is faulty – replace it
If installed – replace the internal thermal protection and/or the start-up relay and/or
the start-up capacitor and/or the working capacitor.
DMC51 – The led
is ON – see specific point.
If the compressor still does not work, replace it.
If ESS=YES (see
section 8.12.7) - The
compressor remains
OFF unexpected short
time.
The OFF time of the compressor is related to the actual dryer thermal load. If dryer is
running in low or no-load conditions and at mild/low ambient temperatures, and the
compressor remains OFF for too short time (less than 3-5 minutes), check which of the
following reasons is creating the malfunction:
1. The DewPoint probe T1 doesn’t correctly detect the temperature - ensure the sensor
is pushed into the bottom of probe well.
2. The thermal insulation of DewPoint probe T1 is damaged – restore the thermal
insulation
3. The ambient temperature is too high or the room aeration is insufficient - provide
proper ventilation.
4. The solenoid valve EVL is not operating correctly - see specific point.
5. If installed - The check valve CHV is jammed (open) - contact a BEKO service
technician to replace it.
The fan of the
condenser does not
work
Verify the electric wiring.
PV pressure switch is faulty. Contact a BEKO service technician.
RA CT 200-500 3phase- Blow of fuse (FU1-FU2 on the electric diagram) - replace it
and check the proper operation of the dryer.
There is a leak in the refrigerant circuit – contact a BEKO service technician.
If the fan still does not work, replace it.
