872 Extension Module IC Pump
3 Assembly
3.1 General
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.
Up to three extension modules can be connected to an 850 Professional
IC instrument. The following restrictions are to be taken into account:
Restrictions The 850 Professional IC instruments and their extension modules must not
have more than 4 identical components in common, 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, SPM incl.),
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 longer periods of time.
Extension modules can be mounted in the following setup versions:
￭ above, between instrument and bottle holder (3-A), or
￭ below, between instrument and base tray (3-B), or
￭ next to the instrument (3-C) with a separate 6.2061.110 base tray and
a 6.2061.100 bottle holder (to be ordered additionally). For this, the
longer 6.2156.070 connection cable (to be ordered additionally), is
necessary, too.
