most three digits of the display. The left-most
digit shows, which setting value is indicated on
the display. How to locate the setting values with
the man-machine interface, is described in the

The checksum of the programming switchgroup
SGF1 is indicated on the display, when the cor-
responding setting value is selected. An exam-
ple of calculating the checksum and detailed in-
formation of the push-button operations are
given in the general description of the D-type
SPC relay modules.
The number of the switches, 1...8, and the
switch positions, 0 and 1, are displayed during
the setting procedure. In normal service only
the checksum is displayed.
