Note
Blue cells display read-only data; white cells display editable data.
The following data displays for each detector:
Name Description
Det # Numerical identifier for the detector to which the following data applies.
Detector Options, which depend on your GC’s configuration, are TCD, FPD, or FID.
FID Temp RTD Applies to FIDs only. Select the appropriate RTD from the drop-down list.
The RTD measures the temperature of the FID flame.
FID Ignition Applies to FIDs only. Select Manual if you want to control the ignition of
the FID; select Auto if you want the GC to control the ignition of the FID.
Ignition Attempts Applies to FIDs only. Indicates the number of times the GC will try to light
the flame. If an 'Auto' FID ignition sequence fails to light the flame after
the specified number of attempts, the GC will close the hydrogen valve,
switch the FID ignition parameter to Manual, and set an active alarm.
Wait Time Bet Tries Applies to FIDs only. Indicates the amount of time, in seconds, the GC will
wait between ignition attempts.
Igniter On Duration Applies to FIDs only. Indicates the length of time that the igniter will
remain on.
Flame On Sense Temp Applies to FIDs only. The flame ignites when the FID internal temperature
exceeds the value set in this field.
Flame Out Sense Temp Applies to FIDs only. The flame is extinguished when the FID internal
temperature falls below the value set in this field.
FPD Flame Status DI Applies to FPDs only. Allows you to select from a list of available digital
inputs. The digital input that is selected will receive the FPD’s flame status
value.
Preamp Val FID count. Read-only. See “Resetting the preamp value” on page 3-22 for
more information.
FID Flame Temp Temperature of the FID flame as read by the RTD. Read-only.
Flame Status Options are: Off, On, and Over Temperature. Read-only.
H2 Valve Cur State Options are: Open and Closed. Read-only.
Scaling Factor Preamp calibration factor.
Igniter Status Options are: Off and On. Read-only.
