6.10.1.5 Differential trip indication (TRIPR)
In the event of a malfunction or interruption of the main circuits due to a fault
scenario, the trip reason of the interruption is indicated via the TRIPR bit field.
The following trip reasons are shown by the TRIPR bit array:
Table 26: Differential trip indication TRIPR
The transmitted trip reasons are reset when the main contacts of the PKE
are closed again and a power flow through the PKE trip block is detected.

6.10.1.6 Relative current value (I-REL)
The PKE-SWD-CP module uses input byte 2 to provide the maximum phase
current and input bytes 5 to 7 to provide relative phase currents L1 to L3.
These currents are represented as relative values within a range of 0% to
255% (0x00 to 0xFF). The relative values transmitted are calculated using the
value of the phase current relative to the value of the set overload release
current. The accuracy of the relative current indication depends on the mea-
sured phase current in relation to the current range of the PKE trip block.
The maximum measuring accuracy of the transferred relative current value is
5 %. This value will be achieved if the phase current being measured
exceeds the minimum trip block currents specified below:

The position test on the PKE trip block, as well as the remote
tripping function when enabled with the R-TRIP output bit, will
result in a trip if the trip block phase currents exceed the speci-
fied values; see ￫ Section "Table 27: Trip reasons for position
test and R-TRIP“).
