DESCRIPTION OF CONTROLS AND INDICATORS
2.3 ARROW KEYS
The up and down arrow keys move the reverse video
highlite up and down within the various menu screens,
or increase or decrease numeric values.
The right and left arrow keys move the reverse video
highlite to the next entry field.
2.4 ALARM LEDS
Green LEDs (labeled 1, 2 and 3) indicate when each
of the three relays are energized. A red LED (labeled
FAIL) indicates a fault condition. When a fault occurs,
the red LED illuminates, a descriptive error message is
displayed, and the action of the output(s) will function
as described in
Section 3.2 (fault value - e.g. 22 mA).
2.1 OPERATING DISPLAY
Figure 2-1 shows the Model 54 C Analyzer front panel
with the operating display screen shown. The conduc-
tivity is continuously displayed in large numerals. The
process temperature and primary current output value
are always displayed on the second line of the oper-
ating display screen. The third line is customer config-
urable.
2.2 FUNCTION KEYS
Function key F1 will always be the (Exit) key. Exit returns
the display to the previous level. Changes made to dis-
play are
not sent to memory if Exit is pressed.
Function key F4 (Enter) must be pressed to record
changes made to memory. This key then moves the
reverse video highlite (cursor) to the next enterable
field, or menu.
Function keys F2 & F3 are multifunctional. The discrip-
tion shown in the display just above each corresponds
to a specific operation for that key in the function being
used.
