Liquid Crystal Display (LCD)
The LCD contains nine regions that provide the
user with information on the process variable,
engineering units, mode of operation, output
hold condition, fault indication, relay
activation, secondary variable, and key
function assignments. Figure 4-1 shows a
fully energized LCD, Smart Keys, and mode
text.
Figure 4-1. Fully Energized Display And
Supporting Information.
The top set of icons informs the user of an
abnormal operating condition such as a output
HOLD condition, FAULT condition, diagnostic
SPIKE output, or RELAY activation. These
icons are only energized when such a condition
is detected and are active in all modes of
operation.
For the mode of operation indicators (shown as
right arrows grouped next to the mode text),
only one indicator will be lit and will
indicate the current mode of operation of the
analyzer. As a user moves from one mode to
the next, the appropriate indicator will
energize. The mode of operation indicators
are active in all modes of operation.
The process variable is displayed in the three
and one-half digit, seven segment region.
