This chapter explains how to establish alarm set points,
autotune and manually tune and establish cascade con-
trol through the Operations Page of the software.
To configure the alarm outputs, go to the Setup Page of
the software (see related information in the Parameters
Chapter).
For the alarm clearing procedure, go to the Troubleshoot-
ing Alarms and Errors table in the Navigation and
Operating from the Front Panel Chapter.
For background information about alarms; proportional,
integral and derivative control; and cascade, see the Fea-
tures Chapter.
Alarm Set Points
The Series F4P includes two alarm outputs, which can be
programmed as process, deviation or rate alarms.
Process alarms notify the operator when process values
exceed or fall below Alarm Low and Alarm High Set
Points. Deviation alarms notify the operator when the
process has deviated from the set point beyond the devia-
tion limits. Rate alarms are triggered by a change in
temperature or process value that is faster than the se-
lected rate.
For more information, see the Features Chapter. To set
up the alarms, see the Setup Chapter.
Alarm set points are the points at which alarms switch
on or off, depending on the alarm setting. Alarm set
points can be viewed or changed in the Alarm Set Point
Menus (Operations Page).
The Alarm High Set Point defines the high value that,
if exceeded, will trigger an alarm. This value must be
higher than the alarm low set point and lower than the
high limit of the sensor range.
The Alarm Low Set Point defines the low value that, if
exceeded, will trigger an alarm. This value must be lower
than the alarm high set point and higher than the low
limit of the sensor range.
The Alarm Low Deviation defines the deviation value
on the low side of set point at which the alarm will be
triggered.
The Alarm High Deviation defines the deviation value
on the high side of set point at which the alarm will be
triggered.
✔
Note: You may want to set up the alarms with names
that will identify the alarm conditions. See the Setup
Page.
To Clear an Alarm or Error
In an alarm condition, the alarm status light will be lit.
An alarm message will appear on the Main Page if con-
figured to do so. To silence an alarm, the Silencing option
in the Alarm Output menu (Setup Page) must be en-
abled. To silence the alarm, move the cursor to the alarm
message and press the Right key. A message will confirm
the silencing of the alarm, and the alarm status light will
turn off. After correcting the condition that caused the
error or alarm, return to the error or alarm message on
the Main Page, and press the Right key again. A message
will confirm that the alarm is unlatched.
