*1) The nn within the signal name corresponds to the following measur-
ing quantities:
nn = 01 input measuring voltage U1
nn = 02 input measuring voltage U2
nn = 03 input measuring voltage U3
nn = 04 input measuring voltage U4
nn = 05 input measuring voltage U5
nn = 06 input measuring current I1
nn = 07 input measuring current I2
nn = 08 input measuring current I3
nn = 09 input measuring current I4
nn = 10 input measuring current I5
nn = 11 mean value U of first three phaes voltages U1, U2 and U3,
multiplied by
nn = 12 mean value I of first three currents I1, I2 and I3
nn = 13 three phase active power P measured by first three voltage and
current inputs
nn = 14 three phase reactive power Q measured by first three voltage
and current inputs
nn = 15 mean value of frequency f as measured by first three voltage
inputs U1, U2 and U3
DA14-
BLOCK
Blocks the reporting of new measured value by analogue
measuring channel Q, when active
DA15-
BLOCK
Blocks the reporting of new measured value by analogue
measuring channel f, when active

DESCRIPTION:
DAnn-LOW-
ALARM
Has the value equal to logical 1 when the measured ana-
logue input quantity decreases under the corresponding
set value LowAlarm
DAnn-LOW-
WARN
Has the value equal to logical 1 when the measured ana-
logue input quantity decreases under the corresponding
set value LowWarn
DAnn-
HIWARN
Has the value equal to logical 1 when the measured ana-
logue input quantity increases over the corresponding set
value HiWarn
DAnn-
HIALARM
Has the value equal to logical 1 when the measured ana-
logue input quantity increases over the corresponding set
value HiAlarm
