EL3000 CONTINUOUS GAS ANALYZERS | OI/EL3000-EN REV. D 173
Troubleshooting
Note
For the Fidas24 analyzer, the instructions under Fidas24 –
Troubleshooting on page 174 must be observed.
Flow error
Gas lines or filter contaminated, clogged up or leaky
• disconnect the gas analyzer from the gas treatment
system.
• blow out the lines with compressed air or unblock them
mechanically.
• replace filter inserts and fill material.
• check gas lines for leaks.
Gas paths in the gas analyzer kinked or leaky
• disconnect the gas analyzer from the gas treatment
system.
• Check whether the gas lines in the gas analyzer are kinked
or have become detached from the connections.
• Check the gas feed paths in the gas analyzer for leak
tightness (see Checking gas path leak tightness on
page 199).
Outlet pressure not the same as atmospheric pressure
• Make sure that the outlet pressure is the same as the
atmospheric pressure.
• Guide exhaust gases directly into the atmosphere or
through a line with a large internal diameter which is as
short as possible, or into a gas discharge line.
• Do not guide exhaust gases via restrictions or shut-off
valves.
Unstable display of measured value
Vibrations
• Provide measures to reduce the vibrations.
• Increase the low pass time constant (see Set low-pass
time constant on page 148).
Leaks in the gas feed paths
• Check the gas feed paths in the gas analyzer for leak
tightness (see Checking gas path leak tightness on
page 199).
Loss of sensitivity
• Check amplification drift display of the sample
component (see Drift indicator on page 194).
Uras26: Emitter modulation uneven
• Have the emitter and modulator checked by Service.
Limas23: emission intensity of UV lamp too low or sample
cell contaminated
• Check the intensity display (see Limas23 – Intensity
display on page 179).
• Replace the UV lamp (see Limas23 – Replacing the UV
lamp (EDL) on page 183) or clean the sample cell (see
Limas23 – Clean the sample cell on page 180).
