8. Install the FID cover set screw and tighten using a 3mm Allen wrench.
Note
The next step is important in order to maintain the explosion proof protection of the FID.
The threads of the FID flame arrestor must be clean and lubricant or other substances must
NOT be applied to the threads.
9. Place the FID flame arrestor insert and washer into the FID bottom body and tighten using
a 9/16" open-end wrench. Make sure the flat washer fits into the recessed cavity at the
lower end of the FID bottom body to prevent leaks. See Figures 3-4 and 3-5.
10.Connect the FID flame arrestor insert tubing to the correct connection union in the oven
using either a 1/4" or 5/16" open-end wrench depending on the fitting size.
11.Route the bias cable, the igniter cable, and the signal cable through the EC and connect
them to the FID DPM board locations from which they were unplugged earlier in this
procedure.
12.Route the FID heater RTD cable through the EC and plug it into the DPM location from
which it was unplugged earlier in this procedure.
13.Route the FID heater power cable through the EC and plug it into the PECM location from
which it was unplugged earlier in this procedure.
14.Route the FID heater ground braid through the EC and connect to the appropriate ground
lug from which the old one was disconnected.
15.Turn on utility gases and check for leaks.
16.Turn on power to the analyzer and switch the valves checking all possible flow paths for
leaks. Refer to plumbing diagram provided in the custom documentation package for flow
paths.
17.Turn up oven air to the normal setting and allow the oven to come to temperature and
stabilize.
18.Set all gas flows after the detector is up to its temperature set point.
19.With the new igniter, it will be necessary to start Real Time Chromatograms on the HMI in
order to light the FID flame. On the HMI, choose the Maintenance Menu, and then select
option 5 (Detectors & Real Time Chroms). Then highlight the appropriate FID and then
press "View Chrom".
20.At this time you can ignite the FID using the HMI.
21.After 15 to 30 minutes the analyzer will be ready for operation. Verify that the FID operates
correctly and put analyzer back on line.
