38 Meter Operation
Status Name Description Event ID Descriptor
Average Value
for Current THD
Event
Average THD of last finished THD event,
for the peroid that THD goes beyond or
below the threshold
104 Bits 0-1 of the argument is used to indicate the
phase:
0 = phase A
1 = phase B
2 = phase C
The remaining bits are used for the ITHD value. You
can divide the argument value by 4 to get the THD
value
Average Value
for Apparent
Power THD
Event
Average THD of last finished VATHD
event, for the peroid that VATHD goes
beyond or below the threshold.
105 Bits 0-1 of the argument is used to indicate the
phase:
0 = phase A
1 = phase B
2 = phase C
The remaining bits are used for the VATHD value.
You can divide the argument value by 4 to get the
THD value.
Disconnect
Pulsed
The meter has pulsed the load
disconnect contactor. This may occur
when the physical state of the load
disconnect contactor does not match the
desired internal state. For more
information on this, see “Load Disconnect
Re-Synchronization” on page 1.
106
This event is primarily for diagnostic purposes.
High byte nonzero  Argument format 1
Bit 0 = desired external state
(0 = open, 1 = closed)
Bit 1 = power down pending
(0 => not pending)
Bit 2..15 = low 16 bits of the program counter of
the calling routine
divided by 4
High byte all 0s  Argument format 2
Bits 0..7 = disconnect pulse count
Alarm Events
The following are alarm events that can be selected for inclusion in the event log.
Alarm Name Description Event ID Descriptor
Configuration
Error
Power Line Carrier (PLC)
communications IC initialization failed.
PLC may be non-functional. Urgent
reporting priority is recommended.
37 Echelon internal use
System Reset Watch-dog reset or event buffer overflow
occurred. May be due to momentary
voltage interruption. An unexpected
software error has occurred. Urgent
reporting priority is recommended.
38 0 = Watch-dog timeout
1 = Event buffer overflow, some events may be lost
2 = Abnormal power interrupt
Other codes are for Echelon internal use
