Delay: ”Delay” determines the time the coolant valve remains open af-
ter the process has been stopped. Determines also the time the pump
(only with VMS module and in-line valve) remains running after 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 the coolant valve closes immediately - and that
a pump with VMS module and in-line valve is switched off immediately
- when the process stops.).
