86 Operation Manual
Fault Detection Shuts the oven down if it does not reach setpoint temperature after 16
minutes of continuous cryo operation. Note that this is the time to reach the setpoint, not the
time to stabilize and become ready at the setpoint. For example, with a cool on-column inlet
and cryo control in the oven track mode, it may take the oven 20 to 30 minutes to achieve
readiness.
If the temperature goes below the minimum allowed temperature (–90°C for liquid nitrogen, –
70°C for liquid CO
2
), the oven will shut down.
The COC, MMI, and PTV inlets must use the same cryo type as configured for the oven.
