Unlock the GC Configuration
Accessory devices including inlets, detectors, pressure
controllers (AUX EPC and PCM), and temperature control loops
(Thermal AUX) have electrical connections to a power source
and/or the communication bus in the GC. These devices must be
assigned GC resources before they can be used. Before assigning
resources to a device, you must first unlock the GC
configuration. If you try to configure an Unconfigured device
without unlocking the GC configuration, the GC displays the
message CONFIGURATION IS LOCKED Go to Keyboard options to
unlock.
It is also necessary to unlock the GC configuration if you are
removing the GC resources from a Configured device. This action
returns the device state to Unconfigured.
To unlock the GC configuration, press [Options], select Keyboard
& Display and press [Enter]. Scroll down to Hard Configuration Lock
and press [Off/No].
The GC configuration remains unlocked until the GC is power
cycled off and on.
Ignore Ready =
The states of the various hardware elements are among the
factors that determine whether the GC is Ready for analysis.
Under some circumstances, you may not wish to have a specific
element readiness considered in the GC readiness
determination. This parameter lets you make that choice.
For example, suppose an inlet heater is defective but you don’t
plan to use that inlet today. By setting Ignore Ready = TRUE for
that inlet, you can use the rest of the GC. After the heater is
repaired, set Ignore Ready = FALSE or the run could start before
that inlet’s conditions are ready.
Information displays

[ EPC1 ] = (INLET) (SS) EPC #1 is used for an inlet of type
split/splitless. It is not available for other uses.
