Stability Range The stability range specifies how much a displayed weight may change (in graduations), while the stability indicator remains ON. When the displayed weight changes beyond the allowable range, the stability indicator turns OFF. A value of 0.5, 1, or 3 graduations may be selected.

How Stability Range Affects Operation: • Higher values increase the response time of the indicator but permit the displayed weight to fluctuate within a greater range.

• Lower values decrease response time but limit the allowable range of fluctuation in displayed weight.

In either case, the stability indicator is ON and the displayed weight is considered stable as long as it is within the selected range.

• When the RS232 interface is configured to print stable data only, the stability range also governs the data output. Displayed data will only be output if it is within the selected range.

Custom Unit Conversion Factor If you need to display weight measurements in a unit other than LB, KG or OZ, this feature enables you to create your own unit of measure. You enter a conversion factor which the indicator will use to convert the calibration unit to the desired unit of measure. There are two examples at the end of this section which illustrate how to determine conversion factors.

Once your conversion factor is determined, use the following procedure to enter it.

LFT NOTE: Not available when LFT is set to ON.

28

Entering a Conversion Factor Conversion factors are entered in scientific notation, a method of expressing a number as a value from 0.1 to 1 (called the mantissa), multiplied by a power of 10 (the exponent).

1.

When you access the Custom Unit parameter, the display will show “EPt” for exponent.

2.

Press ENTER to display the current exponent.

3.

Use the numeric keypad to enter the desired exponent. It must be an integer value (no decimals) from -15 to +15.

Conversion Factor Examples Custom unit conversion factors are defined in terms of the current calibration unit: 1 Custom Unit = Conv. Factor x Cal. Unit Example 1: TONS Assume you wish to display weight in Tons and the I150 is calibrated in pounds.

One ton = 2000 lbs, therefore the conversion factor is 2000.

To enter the conversion factor, it must first be converted to scientific notation:

1 Ton

= 2000 lbs

2000

= 0.2 x 104

“.2” is the mantissa (between 0.1 and 1), and “4” is the exponent (power of 10)

Mantissa Exponent

Using this conversion factor, the I150 will display 1 custom unit for every 2000 lbs on the load receiver.

Example 2: OUNCES Assume you wish to display weight in ounces and the I150 is calibrated in pounds.

One oz = 0.0625 lb, therefore the conversion factor is 0.0625.

1 oz

= 0.0625 lb

To enter the conversion factor, it must first be converted to scientific notation: “.625” is the mantissa (between 0.1 and 1), and “-1” is the exponent (power of 10) Using this conversion factor, the I150 will display 1 custom unit for every ounce on the load receiver.

30

0.0625 = 0.625 x 10-1 Mantissa Exponent

Average Display Cycle Average display cycle is used for animal weighing where the movement of animal subjects on the load receiver causes instability and inaccurate weight measurements. Using this feature, you can enter a number of sample readings (from 1 to 255) which the indicator will average before displaying a weight measurement.

Entering 1 for this parameter disables the feature.

Enter the number of readings to be averaged using the numeric keypad, ENTER to return to scale then press ENTER submenu.

Refer to “Animal Weighing� in the OPERATION section for the animal weighing procedure.

LFT NOTE: Does not appear on menu when LFT is set to ON.

Parts Count Error Level The parts counting function of the I150 assumes that all parts are of a reasonably uniform weight. Since there is usually some difference, an allowable percentage of error can be entered. The error is a percentage of the sample part(s) weight.

Acceptable entries can be from: 50 __________ % to 100% resolution To enter a parts counting error level: Enter the desired error using the numeric keypad, ENTER to return to scale then press ENTER submenu

LFT NOTE: Does not appear on menu when LFT is set to ON. 31

Set Point Set point is used to enable checkweighing, filling or emptying for operation. Enabling one of these modes activates the start/stop feature for filling and emptying, and the LED indicators for checkweighing.

Filling and Emptying Processes The I150 enables you to control external feeding devices for filling or emptying weigh hoppers, tanks, etc., to a desired target weight. By entering four system parameters, the I150’s built-in digital outputs can be used to run feeders or emptying devices at full speed, switch to a slower speed, and stop when the target weight is reached. The four required parameters are: Target Weight:

Desired weight of completed batch.

Tolerance Range:

Allowable range of error for target weight.

Dribble Weight:

Weight remaining to reach the target weight, desired to switch feeder or emptying device from fast to slow speed.

When LOAD > TARGET - DRIBBLE; dribble digital output signals feeder or emptying device to switch to slow speed.

Preact Weight:

Weight of material in suspension which falls freely from feeder or emptying device to hopper or tank AFTER it is stopped.

The value you enter for PREACT is used to signal the feeder or emptying device to stop before target weight is reached.

When LOAD > TARGET - PREACT; preact digital output signals feeder or emptying device to stop.

Dribble and Preact values are entered in the SET parameter of the scale submenu.

Target and Tolerance set points are entered in the normal operating mode using the keypad.

Use the following procedure to enter TARGET and TOLERANCE set points: TARGET weight - set point 1 1.

Enter the value using the numeric keypad.

For emptying processes, the target weight must be a negative number.

To make the displayed number nega-/+

Once entered, the current set points can be viewed at any time by pressing FUNCTION followed by the set point key (1 or 2).

Manual Starting and Stopping The process will automatically stop when dribble and preact LEDs turn off. To stop and restart during a process, or to simply start: FUNCTION press FUNC then BTN4.

How To Optimize Dribble and Preact Filling Processes: 1.

Enter a value equal to 10% of the target weight for DRIBBLE, and 0 (zero) for PREACT in the SET parameter. This will cause the feeder to change to slow feed when the load reaches 90% of the target weight, and stop the feeder when the target weight is reached.

2.

When the feeder is stopped, material suspended in air (or the pipeline) will fall freely into the hopper and cause an over-fill. The weight of over-shoot should then be entered for the PREACT value.

3.

Access the SET parameter in the scale submenu and change the PREACT value.

Repeat the procedure as needed to adjust DRIBBLE for optimum fill time, and PREACT for optimum accuracy.

59

Suspended material empties into hopper after feeder stops.

Emptying Processes: 1.

Enter a value equal to 10% of the target weight for DRIBBLE, and 0 (zero) for PREACT in the SET parameter. This will cause the emptying device to change to slow feed when 90% of the target weight has been emptied, and stop when the target weight is reached.

2.

When the emptying device is stopped, material suspended in air (or the pipeline) will fall freely into the receiving container and cause an “overshoot”. The weight of over-shoot should then be entered for the PREACT value.

3.

Access the SET parameter in the scale submenu and change the PREACT value.

Repeat the procedure as needed to adjust DRIBBLE for optimum emptying time, and PREACT for optimum accuracy.
