span). An input channel tag name appears in the upper left corner of the display. A digital readout
for the analog output channel appears under the letters SP in the upper half of the display. The
analog input measured units tag appears in the middle of the display and beneath it a digital read-
out appears under the letters PV. These two displays provide quick recognition of the output level
relative to the process variable.
As shown in Figure 1-2, the Manual Loading Station contains a graphical dot matrix display; hori-
zontal 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 compact in-
strument 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 visibility
and ease of reading. The intensity is a range selectable entry from 0 to 7, with 0 being the bright-
est setting (see Table 4-6).
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; otherwise, the instrument is left in operator
mode for process applications. Both keypads are described as follows:
