2.5 Installation of internal modules
Introduction
Optional modules and valves are easy to install in the instrument. The existing module or Module
Panel is removed with a Torx T20 screwdriver and the cable is disconnected. The cable is then connected
to the optional module, which is subsequently inserted into the instrument. The newly installed module
is then added to the System properties in UNICORN.
Node ID
All of the available optional modules are preconfigured to give the desired function. However, the
function of a module or valve can be changed by changing its Node ID. Node ID is a unit number des-
ignation that is used by the instrument to distinguish between several units of the same type.
In a troubleshooting situation it may be useful to check a valve's or module's Node ID. Refer to Sec-
tion 9.16 Node IDs, on page 503 for a list of Node IDs for valves and modules.
The function of a valve or module is defined by its Node ID, not by its physical position.
Note:
The Node ID is set by positioning the arrows of the one or two rotating switches at the back of the
valve. Use a screwdriver to set the arrows of the switches to the desired number.
A B
The illustration shows an example of a valve module with
two rotating switches.
• The first rotating switch, labeled A, sets the tens
• The second switch, labeled B, sets the units.
Hardware installation of a module
The instruction below describes how to install a module in the instrument.
The illustrations show the principle how to install an optional module. The position of the
module on the instrument and the used type of module will depend on the module being in-
stalled.
Note:
CAUTION
Disconnect power. Always switch off power to the ÄKTA pure instrument before
replacing any of its components, unless stated otherwise in the user documentation.
