COUNT SCALER
Calculating the Count Scale Factor
The count scale factor is used to convert the incoming count pulses to the desired unit of measure to be displayed (feet, gallons, etc.) or to correct for a known amount of error (wheel wear, viscosity, etc.). This scaler has six digits available with a fixed decimal point.
Count Scaler Range: 0.0001 to 99.9999
(Setting the count scale factor to 0.0000 will allow scaling by 100)
Count Scaler (CS) Formula:
cs=E$
where:
DPF is the decimal point factor corresponding to the desired decimal point location.
DISPLAY | DPF | DISPLAY | DPF |
xxxxxx = 1 |
| xxx.xxx = 1,000 | |
xxxxx.x = 10 |
| xx.xxxx = 10,000 | |
xxxx.xx = 100
PPI is the number of pulses per item from the sensor.
Example 1: A sensor produces20 pulses per inch of material travel. Calculate the count scaler required to indicate mate- rial used in whole inches(XXXXXX).
cs= 1 = 0.05000 20
Example 2: An encoder produces 120 pulses per foot. Calculate the count scaler required to indicate material usage in 1/100 ’s of feet (XxXx.Xx).
cs = = = 0.8333 120
(Select the XXXX.XX position on the totalizer decimal point menu).
Programming Count Scale Factor
The first screen in the program mode is used to enter the count scale factor.
;
The far right digit will be flashing. Press the m key until reaching the desired digit value.
Note: Pressing and holding the m key will cause the numbers to autoscroll.
Next press them key to move the flashing digit one place to the left. Change this digit to the desired value with the m key.
Repeat this process until all digits are set correctly.
Programming Decimal Point
The second screen is used to enter the decimal point display on the totalizer screen. Press and hold the m key and
then press them key to move from screen one to screen two.
Press them key to move the decimal point to the desired position.
Programming Offset Value
Programming an offset value allows the counter to reset to a value other than zero. The offset may be up to six digits. The offset cannot be a negative number.
The third screen in the program mode is used to enter the offset value.
The far right digit will be flashing. Press the m key until reaching the desired digit value.
Note: Pressing and holding the m key will cause the numbers to autoscroll.
Next press them key to move the flashing digit one place to the left. Change this digit to the desired value with the m key. Repeat this process until all digits are set correctly.
