ALARM HISTORY
Latest alarm data is updated whenever a new alarm is tripped, and the second latest one is shifted to ‘History 1,’ the third
one to ‘History 2,’ and so forth.

1
Latest alarm trip, parameter number
0 : I1 thr. I3 - Current
1 : IN - Neutral current
2 : U12 thr. U31 - Delta voltage
3 : U1N thr. U3N - Phase voltage
4 : P - Active power
5 : Q - Reactive power
6 : S - Apparent power
7 : PF - Power factor
8 : F - Frequency
9 : I1 AVG thr. I3 AVG - Average (demand) current
10 : IN AVG - Average (demand) neutral current
11 : P AVG - Average (demand) active power
12 : Q AVG - Average (demand) reactive power
13 : S AVG - Average (demand) apparent power
14 : THD I1 thr. THD I3 - Current total harmonic distortion
15 : THD IN - Neutral current total harmonic distortion
16 : THD U12 thr. THD U31 - Delta voltage total harmonic distortion
17 : THD U1N thr. THD U3N - Phase voltage total harmonic distortion

1
Latest alarm trip, parameter point
Shows which point triggered the latest alarm. Bit assignments are identical to those for ‘Alarm,’ address
starting from 8005. For example, ‘0’ at ‘parameter number’ and ‘1’ at Bit 0 of this register address means
that I1 value is lower than the low setpoint, triggering the alarm.
If another point within the same parameter number goes into alarm after one (e.g. if I2 value goes above the
high setpoint while I1 thr. I3 alarm is triggered), the second trip is not recorded in the history.
