The front panel of the relay module contains
two push-buttons. The STEP button is used for
stepping forward in the display and the RESET
button for resetting the red indicators. Addi-
tionally, the push-buttons are used for certain
Part of the settings and the selections of the
operating characteristics for the relay modules
in various applications are made with the pro-

When the checksum calculated according to the
example is equal to the checksum indicated on
the display of the relay module, the switches are
properly set.

checksum of the switchgroup is shown on the
display. The checksum can be used for checking
that the switches are properly set. Fig. 2 gives an
example of calculating the checksum.
