W
a
The measured value exceeds the value range of the analog/digital
converter.
Notify Service.

The temperature of the detector falls below the minimum
temperature.
Status message during the warm-up phase. If the status message
occurs after the warm-up phase: check fuse and replace, if
necessary.

The flame is off.
Status message during the warm-up phase. If the status message
occurs after the warm-up phase: check process gases, check glow
plug.

A
S
a
The analyzer is currently in the fail-safe status.
Causes: flame temperature >
Detector set point +
220 °C, hardware
errors, Pt-100 line break or short-circuit.
Switch power supply off and back on after ≥
3 seconds. If the status
message recurs, notify Service.
Note
Fail-safe status:
Heater off, combustion gas valve closed, instrument air valve
closed, housing purging on, zero gas valve open.
324
W
a
The temperature exceeds or falls below the top or bottom limit value
1.
Status messages during the warm-up phase. If the status message
occurs after the warm-up phase: check whether the permissible
ambient temperature range is observed. Check the connection
leads and connectors. Check the fit of the leads in the wire end
ferrules. Check the overheating protection in the analyzer module
and replace it if necessary.
