The setting values are shown by the right-most
three digits of the display. An indicator close to
the setting value symbol shows when illumi-

t> The operating time of the I> stage, expressed in seconds, when in the definite time
k mode of operation (SGF1/1-2-3 = 0-0-0). The setting range is 0.05...300 s.
At inverse definite minimum time mode of operation the time multiplier k setting
range is 0.05...1.00.

Further, the checksums of the programming
switchgroups SGF1,SGB and SGR1 are indi-
cated on the display when the indicators adja-
cent to the switchgroup symbols on the front
panel are illuminated. The checksums for
groups SGF2, SGR2 and SGR3 are found in
nated which setting value is indicated on the
