The analyzer’s cover must be installed to ensure that the temperatures of
the GFC Wheel and absorption cell assemblies are properly controlled.
If you are unfamiliar with the GFC7001T/GFC7001TM theory of operation, we
recommend that you read Section 13. For information on navigating the analyzer’s
software menus, see the menu trees described in Appendix A.
3.4.1. STARTUP
After the electrical and pneumatic connections are made, an initial functional check is in
order. Turn on the instrument. The exhaust fan should start immediately. The display
will briefly show a momentary splash screen of the TAI logo and other information
during the initialization process while the CPU loads the operating system, the firmware
and the configuration data at the start of initialization.
The analyzer should automatically switch to Sample Mode after completing the boot-up
sequence and start monitoring CO gas. However, there is an approximately one hour
warm-up period before reliable gas measurements can be taken. During the warm-up
period, the front panel display may show messages in the Parameters field.
3.4.2. WARNING MESSAGES
Because internal temperatures and other conditions may be outside the specified limits
during the analyzer’s warm-up period, the software will suppress most warning
conditions for 30 minutes after power up. If warning messages persist after the 60
minutes warm-up period is over, investigate their cause using the troubleshooting
guidelines in Section 12.
