Use and operation
The CVC 3000 VACUUBRAND controller with internal pressure transduc-
er and integrated venting valve can only be operated with components
compatible with the VACUUBRAND VACUU•BUS system, (see “Acces-
sories”, pg. 69). The CVC 3000 vacuum controller controls VACU-
UBRAND diaphragm pumps NT VARIO and VARIO-B, pumping units PC
30xx VARIO, and optional coolant and venting valves.
When switching on the controller CVC 3000 for the very first time, a menu
to select the language of the controller menu is displayed. Select the de-
sired language (e.g., ”English”) by turning the selection knob and press
to confirm. Then select the pressure unit (”mbar”, ”Torr” or ”hPa”) in the
same way.
It is possible to access the language selection menu at any time
by switching on the controller while keeping the selection knob
pressed.
After switching on the device, the
version number of the software is
displayed, followed by the preselected function and the pressure reading.
Connected components (e.g., venting valve, level sensor, external pres-
sure transducer 3000 series) are automatically identified. Identical com-
ponents must be configured beforehand; information upon request.
Do not use more than one controller within the same VACUU•BUS
system. Several controllers in the same VACUU•BUS system will inter-
fere with each other and result in error messages of the connected com-
ponents (pumps, valves).
Attention: Do not assemble or remove plug connections off-axis!
Orient the plug correctly before inserting. To connect additional
components use VACUU•BUS Y-adapters and extension cables. If
an external pressure transducer is connected, it is recognized auto-
matically. Further information on how to use several sensors simul-
taneously is available upon request.
