Channels.
Four Alarms and two Totalizers are assigned to each Recording Channel.
Signal sources derived from universal analog inputs, the optional Modbus serial link, optional digital inputs or internal analog
and digital signals.
Any source can be assigned to any recording channel.
Data from assigned sources can be displayed in:
– Vertical-, Horizontal- or Circular-Chart view format
– Vertical or Horizontal Bargraph view format
– Digital Indicator view format

4.1 Powering up the Instrument
When power is first applied to the instrument, its processor carries out a number of self-tests and displays the start-up screen. At the
end of the start up sequence the instrument displays the last Operator View that was displayed when the instrument was powered
down.
4.2 Displays and Controls
In normal day-to-day use, the instrument is operated via the Operator Keys located along the bottom of the screen.

Note.
1. Current Values
The Current Value, shown on the digital indicators at either the top (vertical chart view) or right hand side (horizontal chart
view) of the screen, is the latest instantaneous value and its update rate is not affected by the recording sample rate.
If the current value in the digital indicator is displayed in red, recording has been stopped for that channel – see Section 5.4,
page 43 and see Section 6.6.1, page 87.
Traces are shown only when that particular channel is being recorded. When a channel is set to Stop, its trace continues to
be shown for up to one sample period.
2. Alarm Status
– Flashing red border around channel indicator alternating with flashing red alarm event icon – alarm active and
unacknowledged
– Continuous red alarm event icon – alarm active and acknowledged
If any alarm in any process group is active, the Global Alarm status icon ( ) is displayed in the status bar – Fig. 4.3. If any
active alarm in any process group is unacknowledged, the icon is surrounded by a red flashing border ( ).
3. Alarm Event and Operator Message Annotations
Alarm Event and Operator Message annotations are not shown on the chart unless enabled – see 'Chart Annotation' on
page 16 and see Section 6.5.2, page 78.
If Alarm event annotation is enabled and an alarm becomes active, a red alarm event icon surrounded by a channel colored
box is displayed at the point at which the alarm occurred, together with the alarm time and tag, for example:
If more than one alarm occurs in the same sample period:
– and the second alarm on a channel becomes active, its icon is added behind the first.
– and more than one operator message is active (max. six), a second icon is added behind the first.
– the new alarm event icons appear to the left of earlier icons.
– the time and tag of the oldest alarm (right-most icon) only is displayed.
4. Screen Capture
If 'Screen capture' is set to 'Enabled' in Common Configuration (see Section 6.4.1, page 61) and an external archive media
card is inserted in the instrument, an image of any Chart, Bargraph, Digital Indicator, Process, Instrument Status/Audit Log,
Alarm Log or Totalizer Log view can be saved to the external media by pressing the key whenever the Operator Menu
is not open.

While in Historical Review mode:
Recording of new data continues unless stopped from the Setup Menu – see
Section 5.4, page 43.
Invalid historical data (for example, when recording has stopped) is denoted by
'– – –' in the digital indicator.
Where the trace at the cursor position represents more than one sample, the
indicators flash between the maximum and minimum values of those samples.
Menu options remain active – allowing the screen interval to be changed, different
scales and channels to be selected, etc.
Operator messages generated are added to the alarm event log at the present
time, not the time indicated by the cursor.
All data stored in the instrument's internal memory can be viewed.
The display can be scrolled back to the start of the oldest data.
Archiving to removable media does not occur but all data recorded in the internal
memory buffer during this time is archived on exiting Historical Review mode.
Select 'Goto' to move to data stored in the instrument's onboard memory that was
recorded at a specific date and time.
Note.
If daylight saving is enabled (see Section 6.4.1, page 61) and the selected 'Goto'
target date/time is within the daylight saving period, 'Daylight Saving' is displayed
on the dialog box.
Once internal memory becomes full, oldest data is overwritten by newest data. If
historical review has been selected for some time, the oldest data present may no
longer be available.
The instrument exits Historical Review mode automatically after 15 minutes if no
key is pressed.
Select Exit to return to the real-time recording display.

Add one of 24 predefined Operator Messages (see Section 6.4.4, page 68) or one
User-Defined Message to the alarm event log.
If '< user defined >' is selected, a data entry keyboard first appears to enable the
message to be entered (see Fig. 6.5, page 56).
An 'Assign to group' dialog box then appears to enable the message to be assigned to
one or more Process Groups.
The selected or user-defined message is displayed briefly in the status bar. If Operator
Message annotation is selected (see 'Chart Annotation' on page 16) the message is also
added to the chart.
Note. When the instrument is in Historical Review mode, Operator Messages generated
are added at the current time, not the time indicated by the cursor.

If an alarm or operator message is obscuring part of a chart trace, use the Chart
Annotation option to hide or display alarms and messages on the screen. Select the
annotation required. indicates the annotations selected.
The possible combinations are:
No annotation (Alarms and Operator Messages both disabled)
Alarm annotation only
Alarms and Operator Message annotation
Operator Message annotation cannot be enabled unless Alarm annotation is also
enabled.
Note.
If more than 40 icons are present on the screen, chart annotation is disabled
automatically.
When chart annotation is disabled, new operator messages and alarms are still
added to the Alarm Event log – see Section 4.9, page 37.
Note. Applicable only to Circular Chart view in Historical Review mode and is greyed-out
in the menu until 'Historical review' is selected.
Use 'Chart Duration' to change the amount of data displayed on the screen in historical
review mode. A longer chart duration displays more data, a shorter chart duration
displays data over a shorter time period, but in more detail. In both cases, the full trace is
preserved by plotting the maximum and minimum samples for each display point.
Unavailable chart durations are greyed-out.
The chart durations available in the menu are determined by the faster of the primary and
secondary sample rates set for the process group during configuration – see
Section 6.5.1, page 76. Unavailable chart durations are greyed-out.
Table 4.1 on page 17 shows the relationship between sample rate and chart duration for
the Circular Chart view.
Note.
A 'Please Wait' message appears in the status bar while the instrument retrieves
data from storage.
Selecting a different chart duration does not affect the rate at which data is
sampled.
Changing the chart duration causes the time at the cursor position to change.
If the chart duration is changed when in historical review mode, it reverts to that set
during configuration (see Section 6.5.1, page 76) upon exiting historical review
mode.

Note. Applicable only to Vertical and Horizontal Chart views.
Use the 'Screen Interval' to change the amount of data displayed on the screen. A longer
screen interval displays more data, a shorter screen interval displays data over a shorter
time period, but in more detail. In both cases, the full trace is preserved by plotting the
maximum and minimum samples for each display point.
The screen intervals available in the menu are determined by the faster of the primary
and secondary sample rates set for the process group during configuration – see
Section 6.5.1, page 76. Unavailable screen intervals are greyed-out.
Table 4.1 shows the relationship between sample rate and screen interval for the Vertical
and Horizontal Chart views.
Note.
A 'Please Wait' message appears in the status bar while the instrument retrieves
data from storage.
Selecting a different screen interval does not affect the rate at which data is
sampled.
When in historical review mode, changing the screen interval causes the time at
the cursor position to change.
