Red Lion LEGEND - Manual (Page 9)

Shown below is the Main Display Loop. FRONT PANEL DESCRIPTION
The front panel has a clear viewing window to view the two line by eight
character LCD display, with yellow/green or red backlighting. The front
panel meets NEMA 4X/IP65 requirements when properly installed. The
keypad has a key array of two rows by four columns and some keys have a
dual function. The following is a description of each key:
KEYPAD FUNCTIONS
-7-
- Function key F1 is a User Programmable Input. When the key is
pressed, the unit performs the appropriate function as programmed
in the “Program User Module”.
- Function key F2/RST is a User Programmable Input. When the key is
pressed, the unit performs the appropriate function, as programmed
in the “Program User Module”. The “RST” printing on this key is
used as a quick reference for the operator, as long as the function key
is programmed for a reset function.
- The PRS key accesses the Preset and Counter Load Module provided
these values are not programmed for ‘loc’k. If all values are ‘loc’ked,
pressing the PRS key does nothing. Preset values that are accessible
(changeable), can be changed immediately. Within the preset menu,
pressing this key saves the value and advances the display to the next
available preset. Pressing the PRS key at the end of the module exits
the module and returns the user to the main display loop.
- The Left arrow/escape key scrolls to the left in the main display loop.
When programming a numerical value, it selects the digit to the left.
In a sub-menu, it will exit to the next higher level menu in the loop. It
is also used to exit the programming loop. When exiting the
programming loop, the Legend will store all the parameters into
nonvolatile memory and return to the last viewed indication display.
