There are three cases to distinguish depending of the pressure in the clogged position and the num-
ber of clogged positions. In the following paragraphs, the work flows of the different scenarios are
explained with flow charts.
Pressure <80 bar in clogged position (Errors 29 – 34, see section 8.1.2 for error messages)
In the flow chart is shown that the SpeedExtractor will be in the “wobble position”. This means that the
heating block is slightly moving up just to increase the volume inside the extraction cell. The position is
still tight, but the pressure will be decreased due to the larger volume now inside the cell.
