EL3060 CONTINUOUS GAS ANALYZERS | OI/EL3060-EN REV. A 137
Troubleshooting
Flow error
Gas lines or filter fouled, clogged up or leaky
• Disconnect gas analyzer from the gas conditioning system.
• Blow compressed air through gas lines or mechanically clear them.
• Exchange filter elements and filter beds.
• Check gas lines for seal integrity.
Gas feed paths in the gas analyzer kinked or leaky
• Disconnect gas analyzer from the gas conditioning system.
• Check whether the gas lines in the gas analyzer are kinked or have be-
come detached from the connections.
• Check gas feed paths in the gas analyzer for seal integrity.
Outlet pressure not the same as atmospheric pressure
• Ensure that the outlet pressure is the same as the atmospheric pressure.
• Conduct waste gases directly into the atmosphere or through a line with
a large internal diameter which is as short as possible, or into a gas dis-
charge line.
• Do not conduct waste gases via restrictions or shut-off valves!
Measured value display is not stable
Vibrations
• Provide measures to reduce the vibrations.
• Increase the low pass time constant (see page 90).
Leaks in the gas feed paths
• Check the gas feed paths for seal integrity (see page 117).
Loss of sensitivity
• Check amplification drift display of the sample component (see page 121).
Uras26: Emitter modulation uneven
• Have the emitter and modulator checked by service.
