Varian, Inc. User Manual CP-4900 Micro-GC Page 77
Instrument
Select for each CP-4900 Micro-GC connected a unique instrument identity.
This setting is used for the UserDataStore library (a common shared database for data
exchange between applications) in which all kind of results, status, etc information is stored.
Set the instrument number on one for the first instrument, two for the second, etc.
Remote access CP-4900 status (UserDataStore)
Select this setting to store the instrument status into the UserDataStore library.
In instrument control the status is continuously stored into the UserDataStore library. The
instrument status will become accessible for other applications like the Varian userlink
applications PCI1000Com, Mlink32, I/O-Control or any other self-written program. Also the
instrument status as stored into the UserDataStore database can be used for external relay
setup, see item “Remote control external relays”.
Remote control external relays
Select this setting to enable control of the two integrated relays and extended “Extension Box”
relays (optional). If activated, extra relays switch conditions will appear in the Alarms-Events
Tab of Instrument Method Setup.. Relays already configured in Auto sampler setup cannot be
used, see item “Auto sampling”. Relays can be used for alarming and relay programming
purposes.
Acquire auxiliary traces
Select this setting to activate acquiring auxiliary traces.
Auxiliary traces consists of
six external analog inputs, ambient temperature and pressure on
page 40 from the sensors located on the mainboard of the CP-4900 Micro-GC.
CP-Maitre Elite can draw plots of these traces; see topic
Auxiliary traces on page 91 in the
Instrument method setup.
In the
Aux Traces Tab on page 103 of the Instrument method setup scaling factors and offsets
can be defined for the six analog input signals.
Extension box connected
The driver automatically selects this option when the configuration is uploaded. So better never
select it manually, but press the “Upload” button and check if this option is selected. Make sure
always to reboot the CP-4900 when an “Extension box” is connected. The CP-4900 only checks
at startup if an Extension Box is connected!
