Limit used in squar

ocessing. A value of zer

cent of scale is used in block

ocessing
if the transducer falls below this limit, in % of scale. The featur

used to eliminate noise near zer

The block alarm is used for all configuration, har
dwar

e or system pr
oblems in the block. The cause of the alert
is enter
ed in the subcode field. The first alert to become active will set the Active Status in the status parameter
. As soon as the
Unr
eported status is clear
ed by the alert r
eporting task, another block alert may be r
eported without clearing the Active Status, if
the subcode has changed.

The summary alarm is used for all pr

to become active will set the Active Status in the status parameter
. As soon as the Unr
eported status is clear
ed by the alert
reporting task, another block alert may be r
eported without clearing the Actve Status, if the subcode has changed.
