Automatic valve detection:
When switching on the controller, the configuration of the connected
components is checked automatically. If a valve (in-line valve or coolant
valve) is connected it is detected automatically and controlled by the
VNC 2 until the controller is switched off.
The last mode of operation and the preselected values (e.g., pressure
value or time for switching off) are stored.
If the preselections are chosen appropriately, it is possible to start imme-
diately if similar operating conditions are desired.
If another factory-set mode is selected, the default configuration for this
newly selected mode is adopted; any user-selected parameters are over-
written. The four available factory-set modes are reviewed below. To se-
lect a different factory-set mode, keep the ”Esc” key pressed while switch-
ing on the controller..
The controller features four factory-set modes (see section “General view
of factory-set basic modes”, pg. 45). Each of these modes involves dif-
ferent menu options in the program menu, as follows:
Vacuum control (pControl): Two point control with 5 minutes time delay.
