BCI-C Alarming
The BCI-C unit has three binary input points used to
communicate alarms and one binary output point used to
reset alarms remotely.Those inputs and output points are:
BI 23; Alarm Present. •This object indicates if any
alarms are active regardless of severity. A notification
will be sent to any recipients of the Information
Notification Class object when the point transitions
from No Alarm to Alarm.
BI 24; Shutdown Alarm Present. •This object
indicates if any alarms that result in the shutdown of
the chiller are active. A notification will be sent to any
recipients of the Critical Notification Class object when
the point transitions from No Alarm to Alarm.
BI 25; Last Diagnostic. •The active text of this object
will reflect the description of the last diagnostic to
occur on the chiller.
BO 2; Remote Diagnostic Reset Command. •This
object is used to remotely reset diagnostics on the
chiller. Immediately after commanding this point value
to 1, the BCI-C will send the reset command to the
chiller and set this point value back to 0 and clear the
priority array.
Note: Not all diagnostics are able to be reset remotely.
Some will require local reset at the chiller front
panel.
