partition, and partitions three and four are occupied by the two contact inputs. All six tag names
for this display are selectable entries. There are also selectable entries that define how each con-
tact input display message is differentiated from the others to indicate an alarm state.
As shown in Figure 1-2, the 53IT5100 Indicator/Totalizer contains a graphical dot matrix display;
horizontal and vertical keypads; a MINI-DIN configuration port connector concealed behind the
front panel pull-down door; terminals for signal input/output wiring and power wiring; and a com-
pact instrument case that protects the instrument main printed circuit board and internal power
supply.
The display is a 96 X 48 gas discharge dot matrix, contrasted orange-on-black to enhance visibil-
ity and ease of reading. The intensity is a range selectable entry from 0 to 7, with 0 being the
brightest setting (see Table 4-10).
To the right of the display is the vertical keypad and directly beneath the display is the horizontal
keypad. Both keypads have functioning push buttons that are dependent on the instrument mode
of operation which can be either operator mode or engineering mode. Mode selection is made
with the Mode (
● ) push button on the horizontal keypad. Engineering mode is entered to make
the necessary selections for the operator displays and Datalink communications port; otherwise,
the instrument is left in operator mode for process applications. The vertical keypad is dedicated
only to engineering mode functions and has no effect in operator mode. Both keypads are de-
scribed as follows:
