How to monitor measured values

You can monitor all measured values via MEASUREMENTS in the HMI menu. In
addition, the measured current values on phases I
of I can also be monitored by activating the monitoring state.

To access the measured values on phases I
I and TH LEVEL via the HMI menu:
(unbal)
1. Press an arrow button to access the main menu.
2. The cursor is at the first menu item, MEASUREMENTS. Press
measured value on phase I
3. Use and to monitor the measured values on phases I
measured value of I
multiples of the rated current I
I , while I is shown as a percentage of the highest phase current and TH
n (unbal)
LEVEL is shown as a percentage of the thermal trip level. Press
see the corresponding primary current value for L1, L2, L3 and I
. If the conversion factors are set to zero, dashes "- - -" are
for I , I , I and I

4. Use the arrow buttons to monitor other measured values in the menu DEMAND
VALUES; see Fig. 4.2.1.2.-1.
5. Press to return the display to the idle mode.
