Measured data
The measured values are displayed by the three
right-most digits of the display. The currently
displayed value is indicated by an illuminated
LED indicator on the front panel of the relay.
Indicator
Measured value
U1
Bus voltage U1 as a multiple of the rated voltage U
n
.
Submenu 1:
Voltage difference between voltages U1 and U3 (U1-U3) as a multiple of the rated
voltage U
n
.
Submenu 2:
Frequency difference between voltages U1 and U3. The sign indication of the
frequency difference is shown on the display as follows:
No sign
f
U1
> f
U3
" - "
f
U1
< f
U3
Submenu 3:
Phase angle difference between voltages U1 and U3. The sign indication of the
phase angle difference is shown on the display as follows:
No sign
U1 leads U3
" - "
U1 lags U3
Note!
The red submenu digit 1, 2 or 3 is substituted by a minus sign (" - ") if the voltage,
frequency or phase angle difference is negative.
