Another thing to know is the allocation of the filters to the respective links. Each filter is
allocated to a link and a filter number by means of hex-coded rotary switches. Each rotary
switch can be set to positions from 0 to F (16 positions) by means of a small screw driver.

This adjustment is important if you want to insert a module into a Main Unit or Extension
Unit as the hex-coded rotary switches have to be set according to the Unit. If the module was
inserted in the factory you don’t have to care about that.

The following figure shows where the hex-coded rotary switches are located and the table
shows the allocation.

Example: Rotary switch for filter 2 UL (right hand side at the bottom) in Extension Unit 2 has

Extension Unit 3 can also be the fourth module in an 8K cabinet.
