8.3 Settings and Measured Values for 4-Wire Wye (4-W)
with Firmware Versions 05 and above
8.3.1

"I/O Module" Tab

On the "I/O Module" tab, you can configure all three general settings, delete
min./max. values and configure the energy measurements. These settings apply
to the entire I/O module.
• In "General," select the network topology to use and the line frequency of
the power supply network from the list fields. Select the phase for which the
peak values are to be specified as well.
In addition, you can disable the watchdog. The watchdog is enabled by
default and trips if no process data is received within 100 ms. The tripping
is signaled by the deactivation of the green "A" status LED. If the watchdog
is disabled, the green LED remains lit.
• For "Voltage transformer (VT)," select from the list field the desired
resolution for the primary voltage and the secondary voltage of the voltage
transformer that is to be used. For the voltage transformer ratio, specify the
values for primary voltage and secondary voltage. The values are saved in
the scaling setting in the I/O module. The voltage transformer ratio is then
already taken into account when measured values are output.
• For "Min./Max. Values," you can reset a specific minimum or maximum
value by selecting this value from the list field and clicking [Delete]. This
action is performed immediately.
• For "Energy," select the desired scaling factor from the list field. The energy
values are transferred to the process data with the configured scaling. If
necessary, reducing the scaling can prevent a process value overflow.
Enter the interval for cyclic energy consumption storage in seconds in the
text field.
• Finally, you can specify thresholds for the energy measurements (active
power, reactive power and apparent power). This allows you to keep
creepage currents that are inherent to the system from affecting the energy
measurement. The energy measurement is interrupted as soon as there is
an underrun of one of the set values.
See also section "Appendix" > "Parameter Assignment".
With the Rogowski version, also specify which coil you are using for
measurement: RC70, RC125, RC175, RT500, RT2000 or a user-defined coil.
