Fault 214—Front detector flame out
Fault 215—Back detector flame out
This message appears when the FID or FPD is not able to ignite or if the flame
goes out during a run. During the ignition process or the run, the detector will
try to ignite the flame twice; if both attempts fail, the hydrogen, air, and ignitor
will shut off, and the error message will appear. The detector will be in a not
ready state.
• Make sure the hydrogen and air are turned on and that the flow rates are
high enough for the flame to ignite.
• Use an electronic leak detector to search for and correct leaks around the
detector column fitting.
• See the discussion of your detector in the Detectors volume to make sure
that you are using the correct jet for your column.
• Change the Lit Offset to 0.5 for the FID or 0.2 for the FPD (the default value).
• If problem persists, contact your Agilent service representative.
Fault 216—Front TCD filament open
Fault 217—Back TCD filament open
The TCD filament bridge voltage indicates that the filament resistance is too
high (or “open,” in the electrical sense). The resistance may be too high because
the filament is broken or worn thin from use, or the wires from the TCD are not
connected on the detector board, or if the cell temperature sensor (∆PRT) is
shorted.
The detector will not be ready until the condition is corrected.
• Check that the wires from the detector are connected on the detector board.
• Check the cell temperature sensor (∆PRT).
• The TCD cell must be replaced. Contact your Agilent service representative.
