Checking the connection and settings of the MMIs

The connection and settings of the connected modules can
now be reviewed via the UMD 98LB display or the "Act Data"
in the ENVIS.Daq.
The measured values of the MMIs can be found on the UMD by going to:
Menu → Local Bus → LB – Current
... and the respective measurement
The display of the currents can be used to review plausibility. If you do
•
not know the current, we recommend comparing the current with a cur-
rent clamp.
When displaying the individual active powers, consumption is displayed
•
without a prefix and supply with a negative prefix. This permits verification
of the correct installation and connection of the current transformers.
The pointer diagram in the ENVIS.Daq can be used to check the rotating
•
field and assignment of the current and voltage paths. Observe the phase
shift of current and voltage for this.
