PROGRAMMING AND CHANGING DATA
Changing tank parameters can be performed from either the Single-tank or the
Multi-tank screen by activating the programming
function when viewing the appropriate
parameter screen.
Programming is initiated by pressing the <PROG> key which activates the numerical
keypad on the front panel. A flashing curser appears on the screen and the system is now in the
programming mode awaiting input from the keypad. The program mode can be terminated by
either: A. Pressing the <PROG> button again which terminates programming at the point where
the programming function was entered and no changes to the entry are made
B. Pressing the <RUN/PAGE> button which terminates the programming mode, no
changes to the field are made and returns the system to the inventory screen last
viewed
C. Pressing the <ENTER> button which records the new entry in the data field and
either moves to the next programmable data field on the page or moves to the next
screen and terminates the programming mode.
ACCESS CODES
The system recognizes three codes that allow access to restricted programming areas.
These three unique codes are programmed through the system and correspond to three levels of
clearance: Low, High, and Master. The Master access code is reserved for areas in the system
which are used to initially set up the system parameters and is not normally accessable to plant
personell while High and Low access codes allow Operator entrance to select areas.
As previously stated all display pages may be viewed and all viewing functions can be
executed without any access code requirement. In these cases operation of the function begins
immediately upon selection of a particular function command.
However, programming requires that a valid access code be entered before execution of
the desired procedure can be permitted. When access codes are required the access code prompt
will be displayed. If a valid code with equal or higher clearance than that required by the
selected procedure is not entered at this point, the system will deny access to that procedure.
