PROGRAM PRESETS & COUNTER LOAD MODULE
The Preset and Counter Load values are accessed from any of the indication
displays, or from any of the main menus in the programming loop, by pressing the
PRS key. The top line shows the Preset number and the display that it is assigned
to (P = Process, B = Batch, T = Total, R = Rate). The following flowchart shows
only the Preset and Counter Load portion:
PRESETS VALUES
Preset values P1 and P2 activate relay outputs one and two respectively, when
the process counter display value equals the preset value. Outputs (presets) one
and two are assigned to the process count display. Presets P3 and P4 activate
solid state outputs 03-SNK & 04-SNK respectively, when the assigned display
equals the preset value. Outputs (presets) three and four can be assigned to either
the Batch counter, Total counter, or Rate indicator display. The output action
(timed, latched, or boundary) is programmed in the Program Outputs Module.
The preset values may range from -99,999 to 999,999.
The Count Scale Factor, will have a direct effect on the preset value being
entered, when the output (preset) is assigned to a counter display. For a Scale
Factor value greater than “1”, the preset value should be a whole number multiple
of the Scale Factor value. If it is not, the Legend will automatically adjust the
preset value up or down to force it to be evenly divisible by the Scale Factor.
COUNTER LOAD VALUE
The Counter Load value (CL) allows the user to change the process or batch
count value. The count display will reset to the counter load value, if the reset
mode is set to counter load (in the Program Counter Module). The counter load
value can be programmed from -99999 to 999999.
