3.2 Extension Module and 850 Professional IC instru-
ment
The extension modules are fitted directly to the 850 Professional IC instru-
ment and connected with it via 6.2156.060 connection cable. Extension
modules have no power supply of their own, but rather draw the electric-
ity they require from the instrument with which they are connected.
Extension modules can be mounted above (between instrument and cov-
ering plate) or below (between instrument and base tray) the 850 Profes-
sional IC instrument or set up next to the instrument with separate (to be
ordered separately) 6.2061.110 base tray 6.2061.100 and covering plate .
Up to three extension modules can be connected to a 850 Professional IC
instrument. The following limitation is to be taken into account when
doing so: the 850 Professional IC instrument and its extension modules
may not contain more than 4 identical components, i.e. 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
2
suppressors (MCS).
Note
If all 4 high pressure pumps are being used at once, then not all of
them are permitted to run at maximum flow for long periods.
