DRYPOINT® RS 15-550 HP50 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 dryer does not
start.
Check whether or not the dryer is connected with the electric mains.
Check the electric cabling.
RS 180-550 3phase- Blow of fuse (FU3 on the electric diagram) of the auxiliary circuit - replace it and
check the proper operation of the dryer.
◆
The refrigerating
compressor does not
work.
The internal heat protection of the compressor was activated
– wait 30 minutes and then retry.
Check the electric cabling.
If installed
– replace the internal heat protection and/or the start-up relay and/or the starting
capacitor and/or the operating capacitor
.
HPS pressure switch was activated
– see the corresponding point.
If installed
– the LPS pressure switch was activated – see the corresponding point.
If installed
– the TS safety temperature switch was activated – see the corresponding point.
In the event that the compressor still does not work, replace it.
◆
The fan of the
condenser does not
work (air-cooled).
Check the electric cabling.
The electronic control unit is faulty
– replace it
If installed - Fan relay / power contactor (see KF / KV1 on the electric diagram) is faulty - replace it.
RS 180-550 3phase- Blow of fuse (FU1 on the electric diagram) - replace it and check the proper
operation of the dryer.
There is a leak in the refrigeration cycle
– contact a BEKO service technician.
In the event that the fan still does not work, replace it.
◆
Dew point too high.
The dryer does not start up
– see the corresponding point.
The BT1 dew point sensor does not record the temperature properly
– ensure that the sensor is
pushed down to the bottom of the aluminium tube immersion sleeve.
The refrigerating compressor does not work
– see the corresponding point.
The ambient temperature is too high or the room ventilation insufficient
– ensure sufficient ventilation
(air-cooled).
The inlet air is too hot
– re-establish the nominal conditions.
The inlet air pressure is too low
– re-establish the nominal conditions.
The inlet air throughput is higher than the throughput of the dryer
– reduce the flow rate - re-establish
the nominal conditions.
The condenser is dirty
– please clean it (air-cooled).
The condenser fan does not work
– see the corresponding point (air-cooled).
The cooling-water flow is insufficient
– re-establish the nominal conditions (water-cooled).
The dryer does not discharge the condensate
– see the corresponding point.
The hot-gas bypass valve needs to be re-adjusted
– contact a BEKO service technician to have the
nominal setting re-established.
There is a leak in the refrigeration cycle
– contact a BEKO service technician.
◆
Dew point too low.
RS 15-40 The fan is always ON - Led
and led
are flashing - see specific point.
RS 50-550 - The fan is always ON
– Led
is fl display
- see specific point (Air-
Cooled).
The ambient temperature is too low
–re-establish the nominal conditions.
The hot-gas bypass valve needs to be re-adjusted
– contact a BEKO service technician to have the
nominal setting re-established.
◆
Extreme pressure
drop in the dryer.
The dryer does not discharge the condensate
– see the corresponding point.
The dew point is too low
– the condensate is frozen and blocks the air – see the corresponding point.
Check the flexible connection hoses for obstructions.
