Front detector shutdown
Back detector shutdown
Status message: Front det shutdown or Back det shutdown
The detectors will shut down if they experience a pneumatics failure or if the
TCD experiences a filament failure.
The GC will not be ready until the detector with the failure is turned off.
Turning off the FID or FPD turns off the igniter, hydrogen flow, and air flow.
Turning off the NPD turns off bead voltage, hydrogen flow, and air flow.
Turning off the TCD turns off filament voltage and reference flow.
