1.12.2 Manual status
Manual operation is performed and chromatograms are displayed in the manual status.
The operations available in the manual status are as follows.
Oven heater ON/
OFF
When the oven belongs to two GCMs, set both the GCMs in the manual
status, then click the SYS tab and open the “Temperature regulator control”
window to turn on and off the heater.
LSV heater ON/OFF Set the GCM to which the LSV belongs to the manual status, then click the
SYS tab and open the “Temperature regulator control” window to turn on
and off the heater.
FPD detector heater
ON/OFF
Set the GCM to which the FPD belongs to the manual status, then click the
SYS tab and open the “Temperature regulator control” window to turn on
and off the heater.
Hydrogen limiter
ON/OFF
When the hydrogen limiter belongs to two GCMs, set both the GCMs in
the manual status, then turn on and off the limiter in the “GCM Det Control”
window or the “SYS Det Control” window.
Detector ON/OFF Set the GCM to which the detector belongs to the manual status, then turn
on and off the detector in the “GCM Det Control” window or the “SYS Det
Control” window.
Stream valve ON/
OFF
Set the GCM to which the stream valve belongs to the manual status, then
turn on and off the valve in the “GCM VLV Control” window.
Atmospheric
pressure balancing
valve ON/OFF
Set the GCM to which the atmospheric pressure balancing valve belongs to
the manual status, then turn on and off the valve in the “GCM VLV Control”
window.
Built-in oven valves
(RV, LSV) ON/OFF
Set the GCM to which the built-in oven valves (RV, LSV) belong to the
manual status, then turn on and off the valves in the “GCM VLV Control”
window or the “SYS VLV Control” window.
The following operation modes are available in the manual status.
The process status and the manual status can be changed to each other in the stop mode.
When the equipment is switched from the process mode to the manual mode, valves and stream
valves are all turned off.
Run • A mode to perform measurement
• Activate this mode in the manual status to start to display a
chromatogram.
(Peak detection or concentration calculation is not performed.
Chromatograms are not saved.)
Users at Level C or higher are allowed to activate this mode.
Stop • A mode to stop measurement
• Activate this mode to immediately stop the run mode in the manual
status.
Users at Level C or higher are allowed to activate this mode.
