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.
RGTR.
PARAMETER
8129
Latest alarm trip, parameter number
0 : I1 thr. I3 - Current
1 : IN - Neutral current
3P4W
3.00
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
3P4W
3.00
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
3P4W
3.00
16 : THD U12 thr. THD U31 - Delta voltage total harmonic distortion
17 : THD U1N thr. THD U3N - Phase voltage total harmonic distortion
18 : UT12 thr. UT31 - Phase angle between phase voltages total harmonic distortion
8130
Latest alarm trip, parameter point
Shows which point triggered the latest alarm. Bit assignments are identical to those for ‘Alarm,’ register address start-
ing 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 set-
point while I1 thr. I3 alarm is triggered), the second trip is not recorded in the history.
