Delay: ”Delay” determines the time the pump (with VMS module and
in-line valve) remains running and the coolant valve remains open af-
ter the process has been stopped.
The ”Delay” is adjustable in a range of 1-300 minutes or can be set to
”Off” (”Off” means that when the process stops, the pump is switched
off and the coolant valve closes immediately.).
+
Duration: ”Duration” determines the total process time since control
start.
A preset ”Duration” (process time) has no effect if the process is
stopped due to a preset ”Maximum” before ”Duration” is reached.
The ”Duration” is adjustable between 1-1440 minutes (24 h) or can be
set to ”Off”. ”Off” means that no endpoint of the process is defined.
The screen-shot shows the factory-set values.
