When assembling, ensure
vacuum-tightness. After as-
sembly, check the whole system for leaks.
Secure hose connections at the pump appropriately, e.g.,
with hose clamps, to protect against accidental detach-
ment.
To reduce pump noise emanating from the pump exhaust
port, connect an exhaust hose or use a silencer (see “Ac-
The VACUUBRAND controller CVC 3000 can only be
operated with components compatible with the VACU-
UBRAND VACUU•BUS system, (see “Accessories”, pg.
The vacuum controller CVC 3000 controls VACUUBRAND
diaphragm pumps NT VARIO and VARIO-B, pumping
units PC 30xx VARIO, and optional coolant and venting
valves. Connected components (e.g., venting valve, level
sensor, external pressure transducer 3000 series) are au-
tomatically identified and configurated. Identical compo-
nents must be configurated 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 interfere with each other and result in error mes-
sages of the connected components (pumps, valves).
CVC 3000
The CVC 3000 is equipped with an internal capacitive
pressure transducer with ceramic diaphragm. It measures
the actual pressure independently of the gas type, and
with reference to the vacuum, i.e., absolute.
Pumps NT VARIO and VARIO-B:
Connect the controller CVC 3000 via the VACUU•BUS ca-
ble of the NT VARIO or VARIO-B pump to the diaphragm
pump.
Attention: Do not apply off-axis forces when as-
sembling or removing plug connections! Observe correct
orientation of the plug. To connect further components use
VACUU•BUS Y-adapters and extension cables.
