Micromod Micro-DCI: 53IT5100A Indicator/Totalizer - Manual (Page 6)

1.0 INTRODUCTION
1.1 PRODUCT OVERVIEW
The 53IT5100 Indicator/Totalizer provides a suite of six operator displays to monitor process
activity for up to four independent process variables and also provides integration and totalization
for each of the four process variables. The displays are of three types: dynamic bar graph, digital
readout, and alarm summary. There are three bar graph displays, two digital readout displays, and
one alarm summary display. These include a Quad Bar Graph Display (Channels 1-4)
•
two
Dual Bar Graph Displays (Channels 1&2 and Channels 3&4)
•
a Quad Process Digital Read-
out Display
•
a Quad Totalizer Digital Readout Display
•
and an Alarm Summary Display.
The operator displays are paged forward or back, in the order given, by pressing a 2 (page for-
ward) or a 1 (page back) push button on the horizontal keypad of the instrument. The operator dis-
play suite is illustrated in Figure 1-1 and the instrument horizontal keypad is identified in Figure 1-2.
Quad Bar Graph Display (Channels 1-4) - all four channels are arrayed across the display as bar
graphs with the digital readout and measured units of a selected bar graph in the lower quadrant of
the display. A bar graph digital readout with measured units is selected with the 3 push button,
which moves a pointer to the base of each bar graph in the display every time it is pressed. In the
illustration, upper and lower alarm limits appear with each 50 segment vertical axis. The measured
units and alarm limits are selectable entries, as well as the mode of alarm reporting (e.g.,
High/Low, High only, Low only, High/Hi-Hi, Low/Lo-Lo, or none).
Dual Bar Graph Display (Channels 1&2) - two channels are arrayed across the display as bar
graphs with the digital readout and measured units of each channel appearing beneath its bar
graph. The channel tag names appear in the upper quadrant of the display. Each 50 segment ver-
tical axis has a numeric range and alarm limits. The tag names, vertical axis numeric range (zero
and span), measured units, alarm limits, and alarm mode are all selectable entries.
Dual Bar Graph Display (Channels 3&4) - is identical to Dual Bar Graph Display (Channels 1&2)
except it displays process activity from channels 3 and 4.
Quad Process Digital Readout Display - is a process activity digital readout of all four channels
that is refreshed every second. The display is divided vertically into four quadrants, each one dedi-
cated to a channel. Each channel readout has a tag name, numeric value, and measured units
field. The tag names and measured units are identical to those selected for the bar graph displays.
Quad Totalizer Digital Readout Display - is an integrator accumulator digital readout of each of
the four channels that is refreshed every second. The display is divided vertically into four sec-
tions, each one dedicated to a channel. Each channel totalizer has a tag name, accumulated
value, and totalizer measured units field. The tag names and measured units are selectable en-
tries.
Alarm Summary Display - presents six alarm states relevant to the four input channels and two
contact inputs. The display has four partitions with the uppermost containing the display title. The
word ALARM in the title flashes should an alarm condition occur with any one of the channel in-
puts or if a contact input is activated indicating an alarm. The specific channel or contact input in
the alarm state is also differentiated from the rest of the display coincident with the ALARM banner
flashing in the title of the display. The four channel inputs are listed together in the second
