74 Agilent 7697A Troubleshooting
6 Pressures and Flows
Flow and Pressure Shutdowns
The HS monitors the vial pressurization gas stream. If the
optional G4562A Carrier Gas EPC module is installed and
enabled for use, the HS also monitors the carrier gas flow. If
a gas is unable to reach its flow or pressure setpoint, the HS
assumes that a leak exists. It will warn you with a beep
after 25 seconds, and it will continue to beep in intervals.
After about 5 minutes, the HS will shut down components to
create a safe state.
In general, a flow or pressure shutdown will not stop
ongoing vial equilibration processing. However, no new vials
will be handled. The HS will not perform injections.
