Interfering gas error
For this channel, an interfering gas is taken into account (i.e. O

over N
2
).
This interfering gas is measured by another channel. This event occurs
when the other channel:
•
is in error (sensor out, thermal cut off, calibration, etc.)
•
does not exist anymore
•
does not measure the right gas (i.e. O
2
)

not updated
The PROFIBUS-DP module has not received
measurements from the instrument for 30 seconds.
