Alarming
Action
Alarming: require
manual
acknowledge
- If set, any alarm appearing in the Meter Alarms, registers (I-30 through I-37)
must be manually acknowledged
by writing a “1” bit to the corresponding bit
in the “Acknowledgement Required” registers (meter relative), subject to
further constraints
configured by the other three “Alarming” meter control
options (this register, bits 1, 2, and 3).
- If clear, any alarm is deemed to be automatically acknowledged at the
moment that it occurs: t
he “Acknowledgement required” bit is never raised, so
no “Alarm Acknowledged” record is written to the Alarm Log, and the
following three meter control options have no effect.
-
For more information, see the other three “Alarming” meter control alarms,
the “Acknowledgement required” registers and the “Meter alarms” registers
themselves.
Alarming: Disallow
pre-acknowledge
- If set, the acknowledgement of any alarm requires the alarm condition to
have been resolved and its corresponding bit in the "Meter alarms" registers
to be clear. If clear, then alarm acknowledgement may be performed at any
time after the "Acknowledgement required" bit has been raised, even if the
alarm condition itself has not yet been resolved and the alarm bit is still set; in
this case, the continuing presence of the alarm condition does not cause the
"Acknowledgement required" bit to be re-raised, but after the alarm condition
has been resolved (and its alarm bit cleared) a recurrence of the alarm will
again raise the "Acknowledgement required" bit.
If meter control option "Require manual acknowledge" is clear (this register bit
0), then this option is deemed to be clear and has no effect.
- For more information, see the other three "Alarming" meter control options
(this register, bits 0, 2, and 3), the "Acknowledgement required" registers
(meter relative), and the "Meter alarms" registers (meter relative).
