The setting values are shown by the three
rightmost green digits of the display. The LED

Further, the checksum of the selector switch-
group SG1 is presented on the display when the
LED indicator under the switchgroup is lit. In
this way the proper operation of the selector
switches can be verified. An example illustrating
the manual procedure for calculating the
checksum is given in the manual "General char-
acteristics of C type relay modules".
