4.2.1.2. 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
a
,I
b
and I
c
and the measured value
of I
n
can also be monitored by activating the monitoring state.
To access the measured values on phases I
a
,I
b
and I
c
and the measured value of I
n
,
TH LEVEL 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 on phase I
a
.
3. Use
and to monitor the measured values on phases I
a
,I
b
and I
c
and the
measured value of I
n
,I
2
and TH LEVEL. The phase currents and the value of I
2
are shown as multiples of the rated current, which correspond to the full load
current (FLC) of the motor. I
n
is shown as a percentage of the rated current of the
current transformer (CT) while TH LEVEL is shown as a percentage of the
thermal trip level. Press
once more to see the corresponding primary current
value for I
a
,I
b
,I
c
and I
n
. 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.
