You select the desired mode of the analog input module by setting mode
switches I and II according to the following table.

Note that all the rockers of both mode switches marked with a dot must be
set, and some functions are defined by several rockers (e.g. 8- to 16-channel
operation, broken wire signal for 8 or 16 channels).

To activate the desired modes, press the rockers down on the side marked
with a dot.
