SSPA Commands

The SSPA commands are presented in a tree structured menu format designed for access
and execution of all control functions and to prevent the execution of an invalid entry by
the operator. When the prime power is turned On, the LCD display will contain a
message indicating the SSPA model number and the version number of the firmware
installed in the SSPA.
To select a Command Function press the <ENT> button on the keypad. The LCD display
will indicate:
This will provide the local operator access to the Command Function Menus, which is the
top level structure to start the selection of Command Function Menus to input into the
SSPA.
To sequence to the next Command Function Menu press a ↓ or ↑ arrow button on the
keypad. The SSPA will step to the next Command Function Menu each time a ↓ or ↑
arrow button is pressed. The current Command Function Menu will be displayed on the
LCD display. The Command Function Menus are shown in Figure 3-1.
To select a specific Command Function Menu press the <ENT> keypad button. If a
function is selected in error, press the clear <CLR> button which will return the SSPA to
the main command menus to allow the selection of another function. Any one of the five
Command Function Menus can be selected using this procedure.
Once a Command Function has been selected, use the → or ← arrow key-pad buttons to
sequence through the Operating Mode Commands. Each of the modes will be displayed
on the LCD display. A specific operating mode is selected by pressing the <ENT>
button. If a mode is selected in error, press the clear <CLR> button which will return the
SSPA to the operating menus to allow the selection of another mode.
When an operating mode is selected, a parameter or a digit within the parameter will be
flashing on the LCD display. Use the → and ← arrows buttons to sequence through the
parameters or digits to select the next parameter or digit. A specific parameter or value is
selected by pressing the <ENT> button. If a parameter or value is selected in error, press
the <CLR> button which will return the SSPA to the original parameter or value to allow
another selection.
After selecting a parameter or digit, use the ↓ or ↑ arrow buttons to select the next
parameter, or to increment or decrement the value of a digit. A specific new parameter or
new value is selected by pressing the <ENT> button. If a parameter or value is selected in
error, press the <CLR> button which will return the SSPA to the original parameter or
value to allow another selection.
Each time the clear ("CLR") button is pressed, the SSPA will return to the menu level
prior to the last "ENT" command.
