How to monitor measured values
You can monitor all measured values via
MEASUREMENTS
in the HMI menu. In
addition, the phase-to-phase voltages U
12
, U
23
and U
31
, and the measured residual
voltage U
0
can also be monitored by activating the monitoring state.
To access the measured voltages U
12
, U
23
, U
31
, U
0
, U
1s
(positive phase-sequence
voltage) and U
2s
(negative phase-sequence voltage) via the HMI menu:
1. Press an arrow button to access the main menu.
2. The cursor is at the first menu item,
MEASUREMENTS
. Press
to see the
measured value of the phase-to-phase voltage U
12
.
3. Use
and
to monitor the measured values on phases voltage values. The
voltages are shown as multiples of the rated voltage, U
n
. Press
once more to
see the corresponding primary voltage value for U
12
, U
23
, U
31
and U
0
. If the
conversion factors are set to zero, dashes "
- - -
" are displayed instead.
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.
