Control signals
between the
modules
The figure below schematically illustrates how
the starting, tripping, control and blocking sig-
nals can be programmed to obtain the required
function of the protection.
Fig. 4. Control signals between the modules of the overcurrent and earth-fault relay SPAJ 142 C.
The functions of the blocking and starting sig-
nals are selected with the switches of switch-
groups SGF, SGB and SGR. The checksums of
the switchgroups, are found in the setting menu
of the measuring relay module. The functions
of the different switches are explained in the
user´s manual of the measuring module SPCJ
4D29.
