192 ACF5000 FTIR ANALYZER SYSTEM | OI/ACF5000-EN REV. A
FID: Troubleshooting
Temperature problem
Connection leads of the temperature sensor or the heater discon-
nected
 Check the connection leads and connectors.
 Check the fit of the leads in the wire end ferrules.
 Inspect power supply of the heater.
Unstable display of measured value
Vibrations
 Reduce vibration at the installation site of the analyzer system.
Sample gas path leaking
 Check gas path in the analyzer module and in the sampling modules for
seal integrity.
Loss of sensitivity
 Notify service.
Sample gas outlet pressure too high
 Check air discharge line; it must have a large internal diameter.
 Notify service: Have the air jet injector checked for blocks. Have the in-
strument air pressure checked.
Combustion air contaminated
 Notify service: Have the combustion gas supply and the air purifier
checked.
Fluctuating process gas pressures
 Check the supply of instrument air and combustion gas
Outgassing of hydrocarbons in the H
2
safety valve
(option "Hydrogen monitoring of the analyzer cabinet")
 The outgassing of hydrocarbons occurs only in the first weeks after
commissioning of the analyzer system.
Pressure regulator fault
Unstable pressure values or
pressure regulator output variables not equal to set points
 Check the inlet pressure of the supply gases.
 Notify service.
Zero point drift
Sample gas line contaminated
 Clean sample gas line.
Air purifier is not operating adequately
 Reduce hydrocarbon content.
 Exchange catalyst.
Combustion gas line contaminated
 Clean combustion gas line.
