Red Lion GEMINI 33 - Manual (Page 17)

PRESET VALUES
The Gemini 3300 has three Preset values. Two Presets are assigned to the
Process counter and one is assigned to the Batch counter. Whenever the
counter value equals the preset value assigned to the display, an output action
will occur. This action depends on the previously programmed modes. The
preset values may range from 0 to 999,999. (Refer to “Programming the
Presets, Scale Factor, Timed Outputs & Counter Load Values” section for
instructions on entering the preset values.)
The Scale Factor will have a direct effect on the Process Counter preset
value being entered. For a Scale Factor Value greater than one, the preset
value should be an integer multiple of the Scale Factor. If it is not, the Gemini
will automatically adjust the preset value up or down to force it to be evenly
divisible by the Scale Factor.
WITH PROCESS COUNT DISPLAYED -
“1” - PRESET 1 VALUE
“2” - PRESET 2 VALUE
WITH BATCH COUNT DISPLAYED -
“1” - BATCH PRESET
SCALE FACTOR
“3” SCALE FACTOR - The Scale Factor is accessed by pressing the “3” key.
The number of pulses counted (internal Process and total count values) is
multiplied by the Scale Factor, and scale multiplier which will change the
displayed value accordingly. A Scale Factor Value of 1.0000 and a Scale
Multiplier of 1 would result in a display of the actual number of input pulses
that have been counted. The Scale Factor is used primarily for conversion
from existing pulses per unit of measure to the required displayed units. This
includes conversion from different units of measure (i.e feet to meters, etc.).
The Scale Factor Value may range from 0 to +5.9999. Refer to
“Programming the Presets, Scale Factor, Timed Outputs & Counter Load
Values” section for entering instructions. It is important to note that the
precision of a counter application cannot be improved by using a Scale
Factor greater than one. To accomplish greater precision, more pulse
information must be generated per measuring unit. For example, if 5 pulses
are being received per foot of material, the precision of 10th of feet cannot be
attained by simply programming a Scale Factor of 2.0000, even though the
display is reading in 10ths. In this case, the display will increment by two for
each count input. Thus if an odd Preset Value was entered, such as 6.7 ft., the
Gemini will alter the preset to read in even tenths of feet.
Note: Use of a small Scale Factor in conjunction with a small scale
multiplier could cause the internal count value (Process or Total Counter)
to be exceeded before the 6-digit counter value is exceeded.
COUNTER LOAD VALUES
The Counter Load Values are provided to allow the user to modify the three
counter values. The Counter Load Values of the Gemini 3300 are stored in the
unit’s non-volatile memory upon power down. Accessing the Counter Load
Value for the counter that is currently being displayed is accomplished by
pushing the “E” button, and while holding it down, also pushing the “+/-”
button. See “Programming the Presets, Scale Factor, Timed Outputs &
Counter Load Values” section for entering instructions.
“E” & “+/-” - Counter Load Value for the currently displayed counter.
