ACF5000 FTIR ANALYZER SYSTEM | OI/ACF5000-EN REV. A 191
Analyzer system: Troubleshooting
Display of measured value flashes
Measured signal exceeds measuring range limits
Note: Measured value > +130% MRS or measured value < −100% MRS. In addi-
tion, the status messages 344 or 345 are generated.
Display of measured value flashes alternating with --E--
Error in measured signal processing
 View status messages.
 Search and rectify fault cause.
Only mA display flashes alternating with --E--
Fault in the output current circuit
 Search and rectify fault cause (e.g. line break).
Flow error
External gas lines or filters soiled, blocked or leaking
 Disconnect analyzer system from the gas processing system.
 Blow gas lines with compressed air or penetrate them mechanically.
 Replace filter inserts and fillings.
 Check gas lines for leakproofness:
Gas paths in analyzer system kinked or leaking
 Disconnect analyzer system from the gas processing system.
 Check whether the gas lines in the analyzer system are kinked or have
become detached from the connections.
Temperature problem
Analyzer system still in the warm-up phase
 The assemblies in the analyzer cabinet reach their target temperatures
after approx. 2 hours. The gas sampling probe reaches its target tem-
perature after 3 to 4 hours.
Excessive air movement
 Reduce air movement around the analyzer system.
 Install shielding against drafts.
Ambient temperature outside of permissible range
 Protect the analyzer system from cold and heat sources such as the sun,
ovens and boilers.
 Observe climatic conditions:
Ambient temperature for storage and transport −25 to +65°C
Ambient temperature during operation
with built-in fan (option) +5 to +30°C
With built-in air conditioner (option) +5 to +45°C
Relative humidity during operation
Annual average max. 75%
briefly max. 95%
Seldom and slight condensation permissible if the analyzer system is
switched on and the FTIR spectrometer is purged.
