GASSONIC Observer-i - 6.7.4. Fault Status;Error 2 (03 H); 6.7.7. dB Level (06 H); 6.7.8. Peak Sound (07 H)

GASSONIC OBSERVER-i
63
See the ERROR OUTPUT Section for explanation of errors. Bit 13 is special for Modbus and HART.
When the Gassonic Observer-i is in acoustic test, this bit is set to “1” if the acoustic sound level is
above the desired level, and to “0” – if it is below the desired level. This allows the system to quickly
know if there is an acoustic test problem.
Bit 15 is set to “1” if any of the lower level faults are present. The system can now drill down and find
the root cause. Normally, this is not required at the system level, but only at a test station.
6.7.4. Fault Status/Error 2 (03H)
A read-only accessible register contains the bit map for any internal error that is present. The following
table shows the faults that are represented by each bit in the register.

6.7.5. Model Type (04H)
A read returns the Decimal Value indicating the model number. The Gassonic Observer-i model
number is “6000”. Notice: If a newer Observer-i is designed to replace the Gassonic Observer-i the
model number will be different.
6.7.6. Software Revision Major (05H)
A read-only accessible register contains the major (user) alphanumeric revision value of the Gassonic
Observer-i embedded software expressed in 2 ASCII characters (REV “A” appears as a blank and the
letter A).
6.7.7. dB Level (06H)
A read-only accessible register contains the value of the measured SPL expressed in decibels.
6.7.8. Peak Sound (07H)
A read-only accessible register contains the acoustic test peak sound level expressed in decibels.
