5.4.6 SETPOINT ADJUSTMENTS
Access to the System variables: An ENTRY CODE
NUMBER is necessary to set the Micro-Controller to
the PROGRAM SELECT MODE. In this Mode, Field-
Progammable System variables may be examined
and Set.
ENTRY CODE: Press the DOWN ARROW KEY on
the front panel until the "TITLE PAGE" message
appears. Then press the Center, "CIRCLE" Key to
display the message, "PROGRAM ENTRY ACTIVE,
ENTER CODE #:0". The UP ARROW and DOWN
ARROW Keys are then used to cause the display to
show the Entry Code Number.
Program Numbers (P #'s) and System Numbers (S
#'s) are user variables within the program.
YOUR MICRO-CONTROLLER USES CODE# 61 for
P-numbers.
YOUR MICRO-CONTROLLER USES CODE# 64 for
S·numbers.
The Center, "CIRCLE” Key is pressed to enter the
Code Number and to place the Micro-Controller into
the PROGRAM SELECT MODE. The letter "P"
followed by "-1" and a written indication of the Set
Point (i.e. "LINE 1 SELECTION") will be displayed.
If an incorrect Number is entered or if the Entry is not
completed within Ten (10) seconds, the display will
indicate "PROGRAM ENTRY ATTEMPT FAILED".
Pressing any key will clear the message and re-
display the "TITLE PAGE" to allow another attempt to
enter the Entry Code. The center "CIRCLE" key will
cause the "PROGRAM ENTRY ACTIVE, ENTER
CODE #:__" message to again be displayed allowing
for a new entry attempt.
SELECTING A VARIABLE NUMBER: Each Field
Programmable and System generated variable has
been assigned a Unique "PROGRAM NUMBER".
First refer to the Program Number Assignment list to
determine the Number of the desired variable to be
examined, set or altered. Then set the
Microcontroller into the "PROGRAM SELECT
MODE" as described above. You may then press the
UP ARROW and DOWN ARROW keys as necessary
to advance forward or backward through the
Program Numbers until the desired Program position
has been reached.
When the desired Program is displayed, press the
center, "CIRCLE" key a second time will cause the
display to again show the Program Number and
allow another variable to be selected.
NOTE: Once the Micro-Controller is in the
"PROGRAM SELECT MODE", the center "CIRCLE"
Key is used to "TOGGLE" between the Program
Numbers and their associated, stored values. Each
time the center "CIRCLE" Key is pressed the
alphanumberic display will alternate between the
Program Number and the value stored in its location.
CHANGING SYSTEM VALUES: After the desired
Program Number has been selected and the variable
has been displayed, the variable may be increased
or decreased by operating the UP ARROW key or
the DOWN ARROW key on the front panel.
NOTE: When the UP ARROW key or DOWN
ARROW key is first pressed the value displayed will
change by a count of One (1): If the Button is held
down continuously, the Value will approximately
double each .5 seconds until released.
RETURNING TO NORMAL DISPLAY FROM
PROGRAM SELECT MODE: If no Buttons are
pressed for two (2) minutes, the display will
automatically revert to the "TITLE PAGE" display and
the MicroController will exit from the Program Select
Mode. The ENTRY CODE NUMBER must be
reentered to allow access to the Set Points.
If immediate return to normal display is desired, the
DOWN ARROW key is pressed until position P-O (or
S-O) is reached with the message, "CIRCLE TO
EXIT" is displayed. When the center "CIRCLE" key is
pressed the Controller will exit the Program Select
Mode to the "TITLE PAGE" display.
