EXTERNAL CONNECTION OPTIONS
F1245 has software-controlled AUX inputs and outputs
on the input board (AA3), for connecting the external
switch function or sensor. This means that when an
external switch function (the switch must be potential-
free) or sensor is connected to one of six special con-
nections, this function must be selected for the correct
connection in menu 5.4.
