Kind of input value type, which the
alarm has to react on.
U – RMS voltage
I – RMS current
P – active power
q – reactive power
S – apparent power
PF – active power factor
tG – ratio of reactive power to active
power
FI – phase shift
FrEq - frequency
EPPoS – active energy input
EPnEG – active energy output
EqPoS – reactive energy input
EqnEG – reactive energy output
PAv – 15 minutes’ mean active power
UAv – 10 minutes’ mean voltage
FAv – 10 seconds’ mean frequency.

Alarm type. The fig. 9. presents a
graphic display of alarm types.
n-on – normal (transition from 0 to 1),
n-oFF – normal (transition from 1 to 0),
on - switched on,
oFF – switched off,
H-on – manually switched on; till the
time of alarm type change, the alarm
output remains switched on for good.
H-oFF – Manually switched off; till the
time of alarm type change, the alarm
output remains switched off for good.
