sleep mode, depending on settings.

You can only start the system if the following system conditions exist:

 System pressure is at least 800 mbar.

 Furnace temperatures are at most 50 °C below their setpoints.

 The system has detected that the base line is stable.

 Working temperature of the thermal conductivity detector is at least 59 °C.

If one of these conditions is not met, the system does not start and a message is displayed.
