Flame Ionization Detector (Fid) - ABB PGC2000 Operation And Service Manual

4. If, after six attempts to light the flame, it still is not lit, the ignition sequence terminates and the
hydrogen is shut off.
5. From the Chroma Board screen you can press the F4 (Manual Ignitor On) soft key to request
ignition. This automatically turns on the hydrogen supply.
If an analyzer with an FID has the Flameout LED illuminated on the front panel, it can be ignited
either automatically or manually. When the Chroma Board screen has Auto highlighted, the ignitor
will continuously try to ignite the flame. When Auto Timeout is highlighted, the ignitor will attempt to
ignite the flame for the time specified by Timeout on the Chroma Board screen.

Flame Ionization Detector (FID)

The FID cell (see Figure 4-3) reduces the physical sample to an electrical signal which an
interpretation device such as a recorder can condition and plot.
