intervention. Depending on the type of error, the HS emits
no beep or a single beep.
A series of warning beeps sounds before a flow shutdown
occurs. After a short time the component with the problem
shuts down, the HS emits one beep, and a brief message
displays. For example, a series of beeps sounds if the vial
pressurization gas flow cannot maintain setpoint. The flow
shuts down after 5 minutes. A shutdown message briefly
displays. Press [Clear] to stop any beep. Vials in the oven
continue to equilibrate, but the HS handles no additional
vials and will not perform an extraction or injection.
A continuous tone sounds if using HS carrier gas control
and if hydrogen flow is shut down or if a thermal shutdown
occurs. During a hydrogen shutdown, all HS heaters and
motors turn off.
Error conditions
If a problem occurs, a status message appears. If the
message indicates broken hardware, more information may
be available.
Blinking setpoint
If the system shuts down a gas flow or the vial oven, Off will
blink on the appropriate line of the component’s parameter
listing.
Before resuming operations, investigate and resolve the cause of
the hydrogen shutdown. See Hydrogen Shutdown in the
Troubleshooting manual for details.
