9 ERROR MESSAGES & TROUBLESHOOTING

Different levels of messages are generated by the instrument at need.

9.1 Messages

At power up, the AW400 instrument shows the following sequence of messages:

"MicroChem II"

"S.Rel...."
"Transmitter"

9.1.1 Operation

messages

Messages displayed during operation to clarify what AW400 is doing.

"Loading default database"

is shown when a reset has been performed. After some seconds the instrument goes to normal display mode.

"-calib-"

is shown when the instrument is powered up and when a Channel has been changed. After some seconds the
instrument goes to normal display mode.

"---wash---"

flashing is displayed when the instrument is performing a cleaning sequence. "---wash---" is alternated to a
value that is the last measure before the starting of the cleaning sequence.
Both the displayed measure and the 4–20 mA output signal are frozen at that last value.

"Access denied"

is displayed when the inserted password is not correct.

"password"

is displayed when the menu key is pressed: the correct password must be entered in order to access the
menu.

9.1.2 Error

messages

These messages are displayed when something is not correct in the unit.

"Error, no analog input"

is displayed when analog I/O pc board are missing (or contact in their connectors is failing).

"BadIn"

is displayed if the input signal generated by the sensor is too low, that is the sensitivity is too low.

"Fault"

is displayed if the signal generated by the sensor is too high.

"RTFault"

is displayed when the Thermo resistance is faulty and the instrument is currently using the default temperature
value

"Red LED lit (Watchdog)"

When Red LED watchdog is lit it means the microprocessor circuit is faulty.
