Overcurrent warning
The warning code 200 appears in the display when one or more
phase currents exceed 0.8 x the start value of the overcurrent
unit. The code remains on the display until all phase currents
are below the mentioned limit.

Reading current values
To read the current values measured by the overcurrent
subunit:
Enter the CURRENT mode using the up and down arrow but-
tons.
The display first shows the set start value of the overcurrent
subunit.
Browse to the measured phase current values (1, 2, 3) using the
