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 indicates which display the preset is assigned to. The
bottom line indicates which preset is viewed and the programmed value. The
following flowchart shows only the Preset and Counter Load portion:
PRESET VALUES
Preset values P1 and P2 can activate relay outputs one and two respectively,
when the display value equals the preset value. All outputs (presets) can be
assigned to the process count, rate indication display, or none. Presets P3 and P4
can activate solid state outputs O3-SNK & O4-SNK respectively, when the
assigned display equals the preset value. Only outputs three and four can be
assigned to the Batch Counter, or Total Counter. 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, has a direct effect on the preset value 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 unit automatically adjusts the preset value up or down
to force it to be evenly divisible by the Scale Factor.
COUNTER LOAD VALUE
The Counter Load (CL) value allows the user to start the process or batch
count value from a value other than zero or a preset. The Process and Batch
display reset mode is set in the Program Counter Module. The Counter Load
value can be programmed from -99,999 to 999,999. The Counter Load value is
assigned to the process Counter unless otherwise programmed.
