Figure 3 Proposed setup
Up to three extension modules can be connected to an 940 Professional
IC Vario. The following restrictions are to be taken into account:
Together, the 940 Professional IC Vario and its extension modules must
not contain more than 4 identical components, this means that:
A maximum of 4 high-pressure pumps,
￭
A maximum of 4 peristaltic pumps,
￭
A maximum of 4 injection valves,
￭
A maximum of 4 suppressors (MSM, incl. SPM),
￭
BUT
Only a maximum of 3 degassers
￭
And a maximum of 3 CO
￭
NOTICE
If all four high-pressure pumps are being used simultaneously, then all
of them must not be operating with their maximum flow for long peri-
ods.
Position the Extension Module in such a way that the capillary connections
can be kept as short as possible. If several extension modules are being
used, they should all be installed at the same location above or below
each other. If this is not possible, extension modules that are farther apart
have to be connected together using a longer connecting cable
(6.2156.070).
