14. FAILURE DIAGNOSTICS
A relação que apresentamos serve para simular a grande maioria dos problemas e possíveis causas que podem redundar em parada ou
funcionamento inadequado do Secador de Ar - SRS.
A simplicidade de alguns procedimentos para solucionar os problemas, oferece condições ao usuário, de saná-los sem a necessidade de
Assistência Técnica especializada. Entretanto, persistindo o problema depois de tentadas as ações corretivas relacionadas a seguir, entre
em contato com o POSTO SAC SCHULZ credenciado para este equipamento.
EVENTUAL DEFECT
No led lighting up.
Pressing of Test button, but no condensate discharge.
Condensate discharge only when Test button is pressed.
Drain keeps blowing off air.
Drain in alarm condition.
The dryer doesn't start.
The compressor doesn't work.
Condenser's fan doesn't work.
DewPoint too high.
Dew Point too low
Excessive pressure drop within the dryer.
PROBABLE CAUSE - SUGGESTED ACTION
•
Verify that the system is powered.
•
Verify the electric wiring (internal and/or external).
•
Check internal printed circuit board for possible damage.
•
The service valve located before the drain is closed - open it.
•
The dryer is not under pressure - restore nominal condition.
•
Solenoid valve defective - replace the drain.
•
The internal printed circuit board is damaged - replace the drain.
•
Condensate discharge only when Test button is pressed.
•
The diaphragm valve is dirty - open the drain and clean it.
•
The capacitive sensor is too dirty - open the drain and clean the sensor plastic tube.
•
The capacitive sensor is too dirty - open the drain and clean the sensor plastic tube.
•
The service valve located before the drain is closed - open it.
•
The dryer is not under pressure - restore nominal condition.
•
Solenoid valve defective - replace the drain.
•
Verify that the system is powered.
•
Verify the electric wiring.
•
Activation of the compressor internal thermal protection - wait for 30 minutes, then retry.
•
Verify the electric wiring.
•
If installed - Replace the internal thermal protection and/or the start-up relay and/or the start-up capacitor
and/or the working capacitor.
•
If installed - The pressure switch HPS has been activated - see specific point.
•
If installed - The pressure switch LPS has been activated - see specific point.
•
If installed - The safety thermo switch TS has been activated - see specific point
•
If the compressor still doesn't work, replace it.
•
Verify the electric wiring.
•
ADS 10-100 - The DMC15 electronic instrument is faulty – replace it.
•
ADS 125-480 - PV pressure switch is faulty – replace it
•
There is a leak in the refrigerant circuit - contact a refrigeration engineer.
•
If the fan still doesn't work, replace it.
•
The dryer doesn't start - see specific point.
•
The DewPoint probe T1 doesn't correctly detect the temperature - ensure the sensor is pushed into the
bottom of probe well.
•
The Compressor doesn't work - see specific point.
•
The ambient temperature is too high or the room aeration is insufficient - provide proper ventilation.
•
The inlet air is too hot - restore nominal conditions.
•
The inlet air pressure is too low - restore nominal conditions.
•
The inlet air flow rate is higher than the rate of the dryer - reduce the flow rate - restore nominal conditions.
•
The condenser is dirty - clean it.
•
The condenser fan doesn't work - see specific point.
•
The dryer doesn't drain the condensate - see specific point.
•
The hot gas by-pass valve is out of setting - contact a refrigeration engineer to restore nominal setting.
•
There is a leak in the refrigerant circuit - contact a refrigeration engineer.
•
ADS 10-100 - The fan is always ON - the
- see specific point.
•
ADS 125-480 - The fan is always on – PV pressure switch is faulty – replace it.
•
Ambient temperature is too low - restore nominal conditions.
•
The hot gas by-pass valve is out of setting - contact a refrigeration engineer to restore nominal setting.
•
The dryer doesn't drain the condensate - see specific point.
•
The DewPoint is too low - the condensate is frost and blocks the air - see specific point.
•
Check for throttling the flexible connection hoses.
