Type Name Description
Information
Measure Normal measurement mode.
Filter enabled The gas measurements are filtered.
Sample measurement The sample measurement is started.
Meas. not ready The measurement is not ready (e.g. at startup)
Autotest in progress The autotest is running.
Autotest failed The autotest has failed.
Alarm snooze The alarm snooze is ON.
Sample mode user aborted The sample mode has been stopped because the user has pressed the stop button.
Sample mode stopped
because of time out
The sample mode has been stopped because the maximum time to reach the target
has elapsed.
Sample mode stopped
because of an error
The sample mode has been stopped because of a measurement error (sensor out,
purge failure, etc.).
Warning
Calibration Channel in calibration.
Hold The measurement is frozen.
Alarm low low The gas concentration is below the Alarm LowLow limit.
Alarm low The gas concentration is below the Alarm Low limit.
Alarm high The gas concentration is above the Alarm High limit.
Alarm high high The gas concentration is above the Alarm HighHigh limit.
Calibration required The calibration of the sensor is required.
Service required The sensor requires a service.
Alarm
Channel disabled The channel has been disabled.
Channel out The measurement board has been disconnected (or does not answer).
Sensor out The sensor has been disconnected.
Ext. pressure sensor out The external pressure sensor is out.
Thermal cut off The temperature is above the thermal cut off.
Interfering gas error
For this channel, an interfering gas is taken into account (i.e. O
2
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
).
PROFIBUS-DP value not
updated
The PROFIBUS-DP module has not received measurements from the instrument for
30 seconds.
