Attention: The basic setups Management, Management Plus or VACUU•LAN are selectable only if a
VMS Module A and an in-line valve if necessary are connected!
Notes on choosing the basic setup
The controller CVC 2 II can be adapted to the specific application by choosing the
appropriate basic setup Standard, Management, Management Plus or VACUU•LAN
and choosing an operation mode, two-point control or continuous pumping: The con-
nected components of the chemistry vacuum system have to be preset once only.
The vacuum controller CVC 2 II offers four basic setups depending on
- the components of the VACUUBRAND chemistry vacuum system which are con-
nected to the system.
- the specific user and/or process requirements.
The controller CVC 2 II verifies automatically whether an in-line valve is connected.
Without in-line valve, the basic setups ”Standard” and ”Management Plus” are not se-
lectable.
Warning triangle and symbol in-line valve are flashing:
➨ In-line valve is missing, but is indispensable for the selected
basic setup.
☞ Connect in-line valve or choose appropriate basic setup.
