Alarm Name Description Event ID Descriptor
Access
Lockout
Override
The access lockout settings have been
deactivated.
90 0 = Override condition gone
1 = Override detected
Power Quality
State Changed
A power quality event (sag/surge/over-
current) has been detected. Bit mask, bit
value 1 means event detected, value 0
means event cleared.
91 Bit 0 = phase A sag
Bit 1 = phase B sag
Bit 2 = phase C sag
Bit 3 = phase A surge
Bit 4 = phase B surge
Bit 5 = phase C surge
Bit 6 = phase A over-current
Bit 7 = phase B over-current
Bit 8 = phase C over-current
Voltage Sag
The lowest voltage of the last finished
sag event. The timestamp indicates
when the lowest voltage was detected.
When a sag event occurs, the fractional
part of the voltage value that caused the
event is removed before it is recorded
into the meter event log. As a result of
this truncation, the voltage values in the
event log that correspond to some sag
events may not appear to exceed the
threshold defined for sag events.
98 Bits 0-1 of the argument are used to indicate the
phase:
0 = phase A
1 = phase B
2 = phase C
The remaining bits are used for the voltage value in
volts. You can divide the argument value by 4 to get
the voltage value
Voltage Swell
The highest voltage of last finished surge
event. The timestamp of this event
indicates when the highest voltage is
detected.
When a swell event occurs, the fractional
part of the voltage value that caused the
event is removed before it is recorded
into the meter event log. As a result of
this truncation, the voltage values in the
event log that correspond to some swell
events may not appear to exceed the
threshold defined for swell events.
99 Bits 0-1 of the argument are used to indicate the
phase:
0 = phase A
1 = phase B
2 = phase C.
The remaining bits are used for the voltage value, in
volts. You can divide the argument value by 4 to get
the voltage value.
