Flame Out Led On; Flame Will Not Ignite (Fid); Flame Will Not Ignite (Fpd) - ABB PGC2000 Operation And Service Manual

6. Replace LOCOM PCB (set-up address switch).
Symptom: Cannot contact or use remote networking feature.
Cause: Previous remote communication was not terminated.
7. Search for analyzer that is accessing another remote, or that is itself being
accessed, then terminate the access.
See "REMOTE GC OPERATION OPTION" in Section 4.

Flame Out LED On

Symptom: Flame Out LED indicates flame is out.
Cause: The FID or FPD flame can be extinguished by insufficient burner fuel, air or column pressure
surges, or plugged vent line (possibly moisture).
The flame may in fact be burning and the thermocouple or the associated flame detection electronics
may have failed to detect the flame on condition.
Perform Test Procedure 1 (Carrier, Makeup, and Utility Gas Supplies), Test Procedure 2 (Carrier
and Makeup Gas Flow Adjustments), Test Procedure 29 ("Flame Out" LED Remains On After FID
Flame Ignition), and Test Procedure 34 (Vent Back Pressure), as applicable.
If the flame will not light after repeated attempts to ignite it, go to the next paragraph.

Flame Will Not Ignite (FID)

Symptom: Flame Out LED on and continued attempts to light the flame have failed.
Cause: Flame-out thermocouple and its electronics detect that flame is extinguished. The cause
could be lack of or insufficient burner fuel, air, or in some cases carrier when hydrogen carrier is
used. The jet may be plugged or restricted, preventing burner fuel from passing into the detector cell.
The ignitor or ignitor electronics may be defective. The vent line may be plugged.
Perform Test Procedure 17 (Verification Flame Is Ignited), Test Procedure 16 (FID Will Not Light),
Test Procedure 31 (Plugged Jet or Breather), and Test Procedure 34 (Vent Back Pressure), as
applicable.

Flame Will Not Ignite (FPD)

Symptom: Flame Out LED on and continued attempts to light the flame have failed.
Cause: Flame-out electronics detects that flame is extinguished. The cause could be lack of or
insufficient burner fuel, air, or in some cases carrier when hydrogen carrier is used. The jet may be
plugged or restricted, preventing burner fuel from passing into the detector cell. The ignitor or ignitor
electronics may be defective. The vent line may be plugged.
Perform Test Procedure 17 (Verification Flame Is Ignited), Test Procedure 44 (FPD Flame Will Not
Light), Test Procedure 31 (Plugged Jet or Breather), and Test Procedure 34 (Vent Back Pressure),
as applicable.
