AVL DiTEST ADS 340 List of possible faults / troubleshooting
User Manual 10-3
Device check incomplete.
Replace refrigerant bottle. The device scan can not be completed due to insufficient amount
of refrigerant.
The refrigerant cylinder must be replaced.
Measurement data invalid,
calibration failed. If during calibration incorrect measured data calibration is
detected aborted with this error message.
Not enough refrigerant for
calibration, refrigerant
bottle must be replaced. The calibration can not be performed because the amount of
refrigerant required for the calibration is not available. The
refrigerant bottle must be replaced.
Error message Possible cause(s), Solution
System error An error indicates that the device because of a problem
cannot be used for the time being or permanently.
Charging indicator: red flashing quickly.
Check pressure sensors. It was detected an invalid signal on one of the pressure sensors.
All pressure sensors must be checked
.
Check temperature
sensors. It was detected an invalid signal on one of the temperature
sensors. All temperature sensors must be checked
.
Check weight sensors. One of the scales provides an invalid signal.
All balances must be checked
.
CO
2
concentration is above
safety limit. Air the room.
CO
2
concentration is above the recommended limit.
Make sure there is good ventilation and you leave the room until
the CO
2
concentration has fallen back to normal levels and the red
flashing light goes out
.
CO
2
sensor is not available. CO
2
sensor is not connected.
The device cannot be used for safety reasons.
The CO
2
sensor must be checked.
Pressure of refrigerant
bottle too high. The pressure of the refrigerant cylinder is outside the safety limits.
The device cannot be used until the pressure is back within the
safety limits
.
System pressure too high. The pressure at the couplings exceed the safety limits.
The device cannot be used until the pressure is at the couplings
again within the safety limits
.
