7.4 Display Structure and Menu Navigation
Display Item Structure:
All value, parameter or option selection displays are grouped into menu lists. Items are assigned to a list
according to type and classification. Items that can be used to select options or modify functions are
assigned to ‘menu mode’ lists. Items that an operator may require to view during routine operation, detected
pressure or temperature values for example, are assigned to the normal operational mode list. Lists are
identified by page number, the normal operational display list is page 0. All parameters and options are
assigned to menu mode pages 1 or higher. All Page 0 items are view only and cannot be adjusted.
Normal Operational Mode (Page 0):
At controller initialisation, all display elements and LED indicators are switched on for three seconds, the
display will then show the software version code for a further 3 seconds before initialisation is complete and
the normal operating display (Page 0) is shown. In page 0 ‘normal operational display mode’ the Display
Field will show the final delivery pressure continuously and the Item and Value Fields will initially show the
Information Item display for 35 seconds before reverting to the default temperature display item. All available
Item and Value field option displays (temperatures, pressures, hours counters) can be selected using the Up
or Down buttons at any time. The Item display will revert to the default item after 35 seconds if no further
selection is made. Pressing the Enter button will lock any selected Item display and inhibit return to the
default display. When an Item display is locked the lock key symbol will slow flash. To unlock an Item display
press Up or Down to view an alternative Item display or press Reset or Escape. In page 0 Escape will select
the Status Information Item display and Reset will select any active fault code display or the Status
Information Item display if no faults are active. Unless a selected Item display is locked, the display will
automatically jump to the Status Information Item display at key status change events. The timeout period
before returning to the default Item display is modified in some instances to enable the full range of a set
countdown timer to be shown. No Item values, options or parameters can be adjusted in page 0. If a fault
condition occurs the fault code becomes the first list item and the display will automatically jump to display
the fault code. More than one active fault code item can exist at any one time.
Access Code:
Access to page list displays higher than page 0 are restricted by access code. To access menu mode pages
press UP and DOWN together, an access code entry display is shown and the first code character will flash.
Use PLUS or MINUS to adjust the value of the first code character then press ENTER. The next code
character will flash; use UP or DOWN to adjust then press ENTER. Repeat for all four code characters. If the
code number is less than 1000 then the first code character will be 0(zero). To return to a previous code
character press ESCAPE. When all four code characters have been set to an authorized code number press
ENTER. Access to certain menu mode pages is dependent on authority level determined by the access code
used. An invalid code will return the display to normal operational mode; page 0.
The following pages and access levels are used:
ACCESS LEVEL = USER
(code = 9)
ACCESS LEVEL =
SERVICE 1
(code = 100)
P00, P01, P02
P00, P01, P02,
P08
