15.4.8 Fixed Value Change-Over

As a function of the selected configuration, the reference figures are specified via the
assignment of the
476. Accordingly, there can be a change between the fixed values by connec-
source
tion of the logic signals with the parameters
Fixed frequency change-over 2
75,
Fixed percent change-over 2
By combining the logic states of the fixed frequency change-over modes 1 and 2,
fixed frequencies 1 through 4 can be selected:
Fixed frequency
change-over 1
0 = contact open
By combining the logic states of the fixed percentage change-over modes 1 and 2,
fixed frequencies 1 through 4 can be selected:
