The Exception Status Bits are accessed using the following functions:
07 Read Exception Status - Reads the state of the Exception Status Bits
Further information about the application of these inputs and outputs is given in the "WL MODBUS Communication Manual" WL
Low Voltage Power Circuit Breaker catalog.
Catalog number
9.2.2.4 Metering function
PLUS
Trip units ETU745 - ETU776 can be equipped with a metering function
PLUS
. This, however, requires external voltage transformers
providing a three-phase metering voltage.
In addition to the values for the currents, the metering function
PLUS
provides data on voltages, powers, energy values, power factors and
frequency via the
c
for further processing.
