5 Operation
5.3 Vacuum Controller
Operation
The vacuum controller is operated by its touch screen. To
control the vacuum in the Rotavapor® you need to set two
values. The lower vacuum level (Relay 1 set point) is the ul-
timate vacuum that has to be reached. When reaching the
upper vacuum level (Relay 1 reset point) the vacuum valve
opens again. In between these two levels the vacuum in the
system is being controlled.
