Error 1 - Expansion Valve Not Closing
This indicates that while attempting to close the expansion valve, the HOME position
limit switch closure was not detected. This could mean that either the valve is not
moving properly or the switch is mechanically or electrically malfunctioning.
Error 2 - Flow Valve Not Closing
This indicates that while attempting to close the flow valve, the HOME position limit
switch closure was not detected. This could mean that either the valve is not moving
properly or the switch is mechanically or electrically malfunctioning.
Error 4 - No Supply Pressure
This indicates that there is insufficient air supply pressure to continue. Check the air
supply (either in-house or the cart air supply). A malfunction of solenoid valve SOL1 or
solid state relay SSR5 may also cause this problem.
Error 8 - Reservoir Needs Water
The reservoir is empty and needs water. Fill with one (1) gallon of distilled water. This
error only occurs during startup, immediately after pressing the [RUN] key.
Error 16 - Presaturator Water Empty
The presaturator has run empty due either to an empty reservoir or a malfunctioning
filling system.
Error 32 - Low Pressure Underrange
The low range pressure transducer indicates a pressure below 10 PSIA or equivalent in
other pressure units. The most likely cause is a pressure transducer malfunction.
Error 64 - Low Pressure Overrange
The low range pressure transducer indicates a chamber pressure above 20 PSIA or
equivalent in other pressure units. One possible cause would be a malfunction of the
pressure select solenoid SOL5. This error may also indicate a low range pressure
transducer malfunction.
Error 128 - High Pressure Underrange
The high range pressure transducer indicates a pressure below 10 PSIA or equivalent in
other pressure units. The most likely cause is a pressure transducer malfunction.
Error 256 - High Pressure Overrange
The high range pressure transducer indicates a pressure above 165 PSIA or equivalent in
other pressure units. The most likely cause is a pressure transducer malfunction.
Error 288 - Pressure Transducer Failure
This indicates that a measurement error of greater than 10 PSIA, or equivalent in other
pressure units, was observed on one of the pressure transducers. Likely causes include
pressure transducer malfunction or failure of the pressure select solenoid SOL5.
