Duration: ”Duration” determines the total process time since control
start.
The ”Duration” is adjustable between 1-1440 minutes (24 h) or can be
set to ”Off”. (”Off” means that no endpoint for pump down is preset.)
A preset ”Duration” (process time) has no effect, if the process is
stopped earlier by reaching the preset ”Minimum”.
The screen-shot shows the factory-set values.
