14.3 Acknowledging an Alarm
When an alarm condition develops, the LoopName box on the SUMMARY screen for
the control loop involved will turn from blue to red , as will the BF 415 name box.
This is the Visual alarm. A footnote, written in red, will also appear in order to
identify the nature of the alarm (e.g.,
Unit1—Deviation Low Error ).
The Visible alarm will remain onscreen until the alarm condition is rectified.
If
the Audible alarm is also enabled, beeping will occur until the alarm is acknowledged.
There are three ways to acknowledge alarms: (1) one alarm at a time, (2) all alarms
for one control loop at a time, and (3) all alarms for all control loops at a time, for the
rare occasion such a condition should arise.
To acknowledge
one alarm at a time
:
1.
Press the
ALARMS
button to open the
ALARM
screen.
2. Press the red LoopName box to open that control loop’s ALARM screen.
3. Press the Current Alarms button to open the Current Alarms Summary screen
(
see Figure 49
).
