When pressing ”STOP” key, or after process stop due to elapsed ”Du-
ration” (preset process time), the controller is set again to the ”detect”
function.
Temporary switching from ”detect” to ”Vac control” (only if control
is running):
+
Press ”MODE” key. The controller switches to ”Vac control” function,
the current vacuum is used as set value.
+
The preset function of the controller does not change due to this tem-
porary switching. When pressing ”STOP” key, the controller is set
again to the ”detect” function.
➨
Attention:
The ”detect” function is designed for operation with a stand-alone vac-
uum pump. If the CVC 3000 detect is to be operated in a vacuum
network you must ensure that during the determination of the boiling
vacuum no disturbance due to other users will occur.
