pane if the problem exists for two seconds or more. The cryotrap heater controller is shut down.
This fault is non-recoverable i.e. the fault must be addressed and the instrument powered off and
then on again.
12.2.8 Cryotrap Temperature above Maximum
The error CRYO TEMP ABOVE MAX message is generated when the cryotrap temperature exceeds
the maximum of 400°C. This message is displayed on the local display (status line) if the cryotrap
temperature is above 400°C and rising. The cryotrap heater controller is switched OFF. This fault is
non-recoverable i.e. the fault must be addressed and the instrument powered off and then on again.
12.2.9 Inlet Temperature Warning
The INJ TEMP WARNING message is generated when inlet temperature set point cannot be reached
during the method initialization, method run or standby. This message is displayed in the status line
of the Evolution Workstation software. The software checks that the ramp is following its course and
maintained correctly. If the actual temperature is ±50°C from the set point then INJ TEMP WARNING
is displayed. This is a warning and is therefore recoverable.
12.2.10 Cryotrap Temperature Warning
The CRYO TEMP WARNING message is generated when cryotrap temperature set point cannot be
reached during the method initialization, method run or standby. This message is displayed in the
status line of the Evolution Workstation software. The software checks that the ramp is following its
course and maintained correctly. If the actual temperature is ±50°C from the set point then CRYO
TEMP WARNING is displayed. This is a warning and is therefore recoverable.
12.2.11 Inlet Pressure Warning
The PRES WARNING message is generated when the inlet pressure (column flow) set point cannot
be reached during the method initialization, method run or standby. This message is displayed on
the local display and the PC. The software checks that the pressure (column flow) is maintained at
the set point. This message is generated if the actual pressure differs by ±2 kPa from the calculated
set point (which is required to set the column flow) for two minutes. This is a warning and is
therefore recoverable.
12.2.12 Inlet Pressure Error
The PRES ERROR message is generated when Hydrogen is used as a carrier gas and the inlet pressure
(column flow) set point cannot be reached during the method initialization, method run or standby.
This message is displayed on the local display and the PC. The software checks that the pressure
(column flow) is maintained at the set point. This message is generated if the actual pressure differs
by ±2 kPa from the calculated set point (which is required to set the column flow) for two minutes.
The EFC controller is shut down. This fault is non-recoverable i.e. the fault must be addressed and
the instrument powered off and then on again.
