switches
Additional functions required by individual
applications are selected by means of switch-
groups SGF, SGB and SGR indicated on the
front panel. The numbering of the switches, i.e.,
1...8, and the switch positions 0 and 1, are in-
dicated when the switches are set. Under nor-
mal service only the checksums are shown on
the display. The switchgroups SGF, SGB and
SGR are software-based and thus not to be
found in the hardware of the relay module.
