3 PROCESS VARIABLE DISPLAY (Cont.)
CURRENT TRACE ALARM ICONS
In each of the different types of PV display, each channel’s faceplate gives the status of the channel’s
alarms. The status of each alarm is shown by one of the icons depicted in
table 3
, either fl ashing (if it is
active and unacknowledged) or on continuously (if it is active and acknowledged). (See
section 3.1.4
,
below, for a description of how to acknowledge alarms.) Absolute alarm threshold icons and deviation
alarm bars appear in any display which includes a scale (except circular charts). For deviation alarms the
bar stretches from (Reference - Deviation) to (Ref Deviation).
Note: ‘Trigger’ alarms do not display threshold marks or bars, or faceplate symbols.

3.1 STATUS BAR
This appears across the top of the display, and contains the items described below.
3.1.1 Current access level
There are four access levels available (Logged out, Operator, Engineer and Service), and the current level
is displayed in this key at the top left hand corner of the display. Touching this key calls the login page as
described in
section 3.3.1
(Access to confi guration) below. If a user has been added (using the ‘Add User’
part of the Security setup -
section 4.4.3
, below), then the ‘Full User Name’ is displayed instead of the ac-
cess level.
3.1.2 Page name
Initially this shows the current group’s descriptor. The name changes according to context for example
‘Operator’ or ‘Confi g-Archive’ If the Batch option is fi tted, this area contains batch information as well
as the page name. Touching the area calls the Batch Status page. See
section 4.3.10
for further Batch
details.
