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.
The VACUUBRAND controller CVC 3000 can only be
operated with components compatible with the VACU-
UBRAND VACUU•BUS system, (see “Accessories”, pg.
80).
The vacuum controller CVC 3000 controls VACUUBRAND
diaphragm pumps NT VARIO and VARIO-B, and optional
coolant and venting valves. Connected components (e.g.,
venting valve, external pressure transducer 3000 series)
are automatically identified and configurated. Identical
components must be configurated beforehand; informa-
tion upon request.
Connect the controller CVC 3000 via the VACUU•BUS ca-
ble of the NT VARIO or VARIO-B pump to the diaphragm
pump.
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).
VSK 3000
The VSK 3000 is equipped with a capacitive pressure
transducer with ceramic diaphragm. It measures the ac-
tual pressure independently of the gas type, and with ref-
erence to the vacuum, i.e., absolute.
Connect the VSK 3000 pressure transducer via the
VACUU•BUS cable to the CVC 3000 controller.
Attention: Do not apply off-axis forces when assem-
bling or removing plug connections! Observe correct ori-
entation of the plug. To connect further components use
VACUU•BUS Y-adapters and extension cables.
