No. Status Message
300 A S aL No new measured values from the analog/digital converter.
301 A S a The measured value exceeds the value range of the analog/digital
converter.
302 W aQ The offset drift up-scales half of the range permissible.
303 A S aQ The offset drift up-scales the permissible range.
304 W aQ Amplification drift up-scales half of allowed range.
305 A S aQ The amplification drift up-scales the permissible range.
306 W aQ The offset drift between two calibrations exceeds the permissible
range.
307 W aQ The offset drift between two calibrations up-scales the permissible
range.
308 A S aQ A calculation error occurred while calculating the measured value.
309 W a The thermostat works erroneously.
310 W a The temperature correction for this component was deactivated
because the temperature measured value is faulty.
311 A S a The pressure regulator works erroneously.
312 W a The pressure correction for this component was deactivated
because the pressure measured value is faulty.
313 W a No excess sensitivity correction for this component is possible, as
the correction value is faulty.
314 W a No carrier gas correction for this component is possible, as the
correction value is faulty.
315 W aL No new measured values from the analog/digital converter.
Reaction/troubleshooting
Notify Service.
Check sample gas concentration. Check connectors on the gas
analyzer. Notify Service.
Observe drift. As long as the drift is below the value specified in the
measurement data, the measured value is OK. As soon as the drift
exceeds this value, notify Service.
Notify Service. Perform a basic calibration (with Optima TCT Light).
Observe drift. As long as the drift is below the value specified in the
measurement data, the measured value is OK. The detector
concerned will need to be changed soon. Calibrate the detector
displayed manually at the zero point and span point.
Permissible range: 50% of the sensitivity of the detector. As soon as
the drift exceeds this value, notify Service.
Have affected detectors replaced. Notify Service.
Perform a basic calibration (with Optima TCT Light).
Adjust detector displayed manually at the zero point (This message
is created by the automatic calibration) Permissible range: 15 % of
the smallest measuring range that has been installed; 6 % of the
smallest measuring range that has been installed for measurements
on systems subject to approval and systems of the 27th and 30th.
BImSchV
Calibrate the detector displayed manually at the end point. (This
message is created by the automatic calibration) Permissible range:
15 % of sensitivity; 6 % of the sensitivity when measuring on
installations that are subject to approval and installations of 27 and
30 BImSchV
Power-up and power-down the power supply. Notify Service.
