Rules and Guidelines for CONFIGURING HI 4050

Front Panel Display

The Front Panel Display is a 5 line Graphic LCD. The Summary screen displays the

current weight in the selected mode (Gross, Net or available Rate of Change) and the

selected engineering units (lb, oz, lb/oz, kg, g, Ton, t (Metric Ton)). The screen displays

all the menus for Configuration, Calibration, Test and Operation of the HI 4050 Weight

Controller. The four buttons below the display activate the function that is displayed

above. For example to Zero the instrument press the button directly below the ZERO

function. To move from one sub-menu to another press the Up or Down Arrow buttons to

the right of the display. The Up or Down Arrow buttons also increase or decrease

displayed values. The Left and Right Arrow buttons position the cursor on the display.

The Left and Right Arrow buttons are used to select a number in a list.

Entering Alphanumeric Values

To enter a number, letter or punctuation mark use the up or down arrow buttons. Move the

cursor to where you want to enter the value. Press the Up or Down Arrow buttons until

the letter or number you want appears. Press the Right or Left buttons to move the cursor

to the next position. The two punctuation marks are the period (.) and the minus (-) sign.

Repeat to complete the number you want entered.



Button Functions

Zero Button The Zero button is used in Gross mode to zero the selected scale within the tolerance level. This function

can be used as many times as desired as long as the total does not exceed the zero tolerance parameter.

Tare Button Tares the selected scale. The Tare button sets the Net Weight equal to 0. When you are in Net Mode (i.e. a

channel displays Net in the Summary display) the weight changes to 0.00. If you are in Gross mode

nothing happens however, the Net weight is changed to 0.00. The amount is placed in the Tare register and

called a TARE VALUE.

Print Button The Print button prints the Gross, Net and Tare weights to an attached printer. If the Rate of Change

option is activated the print button prints the ROC as well. If the Scoreboard is activated the Print button

does not function.

Enter Button The Enter button when pressed enters the Menus and Sub-Menus. The Enter button also enters the

configured values or selected items form a pick list into non-volatile memory.

Exit Button Takes you back to the previous menu. The Exit button only appears when you enter a menu, it does not

appear on the Summary Display.

Clear Button The Clear (CLR) button clears the total Alphanumeric Entry and repositions the cursor for the first entry.

It is a good idea when a parameter value exists and you want to change the value to clear it before entering

the new value to avoid making mistakes. It only appears when you enter a menu; it does not appear in the

summary or operation displays.



Weight Controller Configuration from the Front Panel.

The Weight Controller Configuration process sets up the instrument to operate as a scale. This

includes configuring WAVERSAVER®, Scale Capacity, Units of Measure, Motion tolerance

and other instrument parameters required for your process. Here is where the permanent

parameters are entered. All the parameters configured except the communication parameters

and IP Address etc. are stored in the Secure Memory Module (SMM-SD).

Step 1. From the Summary

display press the Enter button.

The Configuration Menu

appears.

Step 2. Press the Down arrow

until the cursor is in front of

Instrument Setup (Instr Setup).

Step 3. Press the Enter button.

The Setup Menu appears with

the cursor in front of Units. The

current units parameter is

displayed.

The numbers entered are for illustration purposes

only; yours will vary depending on your application.



Guidelines NOTE: These are example settings depicting a typical system, and your setting

may vary. In most hardy Instrument units, the operation is the same, but the menu order

maybe slightly different.

Unit of Measure Parameters

The Unit of Measure Parameter sets the scale to either English or Metric units The

Selections are:

•Pounds (lb) - Default

•Ounces (oz)

•Pounds/Ounces (lb/oz)

•Ton (Ton)

•Kilograms (Kg)

•Grams (G)

•Metric Ton (t)

Step 1. If the cursor is not in front of Units, press the Down or Up Arrow button until the

cursor is in front of Units.

Step 2. Press the Left or Right Arrow buttons to select the Unit of measure you want.

Step 3. Press the Enter button to save the selection.



Decimal Point Parameter

NOTE: To determine the highest recommended decimal point. Divide the total

load cell capacity by 10,000. Count the number of decimal places in your answer

and use as a reference. Example: 10,000 EU scale divided by 10,000 equals 1.

No decimal point is recommended. 100 EU load cell capacity divided by 10,000,

would equal .01 and two decimal points, or less, would be appropriate.

Step 1. Press the Down Arrow button until the cursor is in front of Decimal

Point. The current number of digits to the right of the decimal point is

displayed.

Step 2. Press the Right or Left Arrow buttons to select the Decimal point position

you want for this instrument.


Decimal Point Parameter

The Decimal Point Parameter is set to determine the resolution you want for the instrument.

Here you set the location of the decimal point for the weight resolution. The higher the number

the farther to the left the decimal point moves and the higher the resolution of the scale. It is

important to note that setting resolution does affect the overall accuracy of the instrument.



Guidelines NOTE: The base graduation number can be found by dividing the total load cell

capacity by 10,000.

10.000/10,000= Grad size of 1

100,000/10,000 = grad size of 10

The graduation size is the minimum increment computed and displayed by the instrument.

There are 10 acceptable graduation sizes to choose from:

1 10 100 1000

2 20 200

5 50 500

Use GRAD sizes when the last digits are not important. If the PLC was configured for three

decimal point and the 10,000 rule says two maximum. Using a GRAD of 10 would send the first

two decimals correctly and the third decimal would always read zero. This will satisfy the PLC

and display a stable weight reading.

Graduation Size Parameter

The Graduation Size is the Minimum increment displayed by the instrument. The Base

Graduation Number can be calculated by dividing the Total Load Cell Capacity by 10,000.

Example:

With two (2) decimal points selected, the graduation size 10 will display increments of.10

engineering units. With two (2) decimal points selected, the graduation size 50 will display

increments of 50 engineering units. (Example: 0.0, 5.0, 10.0, and 15.0)

Step 1. Press the Down

Arrow button until the

cursor is in front of

Decimal Point. The

current number of digits

to the right of the decimal

point is displayed.

Step 2. Press the Right or

Left Arrow buttons to

select the Decimal point

position you want for this

instrument.

Step 3. Press the Enter

button to save the

selection.



Step 1. Press the Down Arrow button until the cursor is in front of Num Averages. The current number

of averages is displayed.

Step 2. Press the Enter button. The Num Averages Menu appears.

Step 3. Use the left or right arrow buttons to move the cursor. When you have placed the cursor in the

location you want, use the up or down arrows to enter the number you want for this application.

Guidelines NOTE: This setting is to aid in ignoring the effects of material impact events. If material

is not entering or exiting the scale evenly unnecessary weight fluctuations can be seen. Averages also

contribute 10 ms each (one update) to the overall time to calculate the scale weight. Applications

requiring very quick weight readings should reduce this setting to it’s minimum. If the weight is

unstable due to material impacting, increase the averages to cover the event time. This sets the number

of weight readings that will be used to compute the displayed weight. The average is a rolling average,

so a new average is available for display at every update.

a. The recommended starting number of average is10 updates or, 100ms delay.

b. Use the numeric keys to enter the new value (range is 1 to 250)

AVERAGES



Guidelines NOTE: The lower the vibration the more steps and time required to calculate the vibration

frequency. Adjust the Average and Waversaver settings to establish minimal weighing time. Use

Waversaver settings 7.5hz – 3.5hz for low amplitude high frequency vibrations. Use Waversaver settings

.5hz – 0.25hz for high amplitude low frequency vibrations.

1. There are 5 selectable levels, plus OFF.

2. Level 1 (7.50hz) provides the least vibration immunity with the fastest response time. (75ms)

3. Level 5 (0.25hz) provides the most vibration immunity with the slowest response time. (2.2sec.)

Typically, mechanical noise (from other machinery in a plant environment) is present in forces larger

than the weight forces trying to be detected. The Weight controller is fitted with Hardy Instruments

exclusive WAVERSAVER® technology, which eliminates the effects of vibratory, forces present in all

industrial weight control and measurement applications. By eliminating the factor of vibratory forces

the Weight Controller is capable of identifying the actual weight data. WAVERSAVER enables the

Weight Controller to distinguish between actual weight data and mechanical noise, both of which are

typically transferred to the Weight Controller by the load cell signal. WAVERSAVER can be

configured to ignore noise with frequencies as low as 0.25 Hz. One of four higher additional cut off

frequencies may be selected to provide a faster instrument response time. The function is user selectable

and can be turned off.

WAVERSAVER®

Step 1. Press the Down Arrow button until the cursor is in front of WAVERSAVER. The current

WAVERSAVER setting is displayed.

Step 2. Press the Right or Left Arrow buttons to select the WAVERSAVER setting you want for this

instrument.




The Low Pass filter can be toggled ON or OFF. When it is ON it provides a more stable weight

reading but at the expense of some reaction time. In most applications a more stable reading is

desired, turn the Low Pass Filter ON. For some applications the Low Pass Filter should remain

OFF to provide a faster update rate. Waversaver efficiency is cut in half, but the update rate is

still every 10ms

Low Pass filter

Step 1. Press the Down Arrow button until the cursor is in front of Low Pass Filter. The state of

the low pass filter is displayed.

Step 2. Press the Right or Left Arrow buttons to toggle


The filter in the OFF mode is normally a check weighing application. The settle time of the

scale, Averages and Waversaver are all time consuming parameters. Reducing the amount

of time required to reach a full weight reading varies. A typical Anyweigh bench scale

could read the correct weight within specified tolerances with the product on the scale for

400ms. Environmental conditions and scale maintenance will also affect scale

performance.



Guidelines NOTE: The base motion number can be found by dividing the total load cell capacity

by 10,000, multiplied by three. Motion tolerance must be greater than or equal to the Graduation

sizes. Recommendation would be three grad size.

This one-second setting time determines if the scale is out of motion and allows the Auto-Zero

tracking feature. If the motion tolerance is too large, auto zero tracking will zero actual product.

Motion Tolerance

Motion is the amount of allowable deviation between consecutive readings before a weighment is

accepted as being complete. Setting Motion Tolerance establishes the amount of deviation you can

allow in your particular process. This parameter examines the weight reading received one second

prior to the current weight reading. If the weight value has changed more than the motion

tolerance the scale is determined to be in motion.

Step 1. Press the Down Arrow button until the cursor is in front of Motion Tolerance. The present

motion tolerance value is displayed.

Step 2. Press The Enter button. The Motion Tolerance Menu appears.

Step 3. Use the left or right arrow buttons to move the cursor. When you have placed the cursor in

the location you want, use the up or down arrows to enter the number and decimal point you

want for your application.

Step 4. Press the Enter button to save the entry.



Guidelines NOTE: This is the weight limit an operator can adjust to compensate an empty scale

with a small amount of product buildup, using the ZERO push button. Normally a Zero

Tolerance amount equal to 2% of the total load capacity is acceptable.

The Zero Tolerance parameter setting limits the GROSS weight units from zero that will be

cleared by the instrument when you push the Zero soft button to Zero the instrument’s GROSS

weight.

Zero Tolerance

Step 1. Press the Down Arrow button until the cursor is in front of Zero Tolerance. The

current zero tolerance value is displayed.

Step 2. Use the Left or Right Arrow buttons to move the cursor. When you have placed the

cursor in the location you want, use the up or down arrows to enter the number and decimal

point you want for your application.




Guidelines NOTE: This is the weight limit Auto Zero Tracking feature or communication

commands can adjust an empty scale. Normally an acceptable Zero Tolerance amount is less than or

equal to 1.5% of the total load cell capacity. When the Auto Zero Tracking feature (0 TRK) is

enabled, the display is reset to zero when the weight is within the set limits and not in motion.

The Auto-Zero Parameter can be turned on to make the zeroing of the instrument automatic. When the

Auto-Zero is turned on the instrument is automatically zeroed, if the motion is within tolerance, every

few seconds until you turn the Auto-Zero off and the value is within the Auto-Zero tolerance value.

This is useful in applications where you are zeroing a scale quite often and don’t want to push the Zero

button each time.

Auto-Zero (tracking)

Step 1. Press the Down Arrow button until the

cursor is in front of Auto-Zero. The

Auto-Zero tolerance is displayed.

Step 2. Use the Left or Right Arrow

buttons to toggle between ON and

OFF.

Step 3. Press the Enter button to save the

entry.

Step 4. Press the Down Arrow button until the

cursor is in front of Auto-Zero

Tolerance. The present Auto-Zero

Tolerance is displayed.

Step5. Press the Enter button. The Auto-Zero

Tolerance Menu appears.

Step 6. Use the Left or Right Arrow buttons

to move the cursor. When you have

placed the cursor in the location you

want, use the up or down arrows to

enter the number and decimal point

you want for this application.

Step 7. Press the Enter button to save the

entry.



The Tare Weight Parameter allows the user to enter a known Tare Weight value for those

applications where you don’t want to push the Tare button each time you weigh something. This

also allows you to save time on check weighing and filling operations. Not having to pause ONE

second to wait for the motion tolerance to settle and then tare can save you time in a process.

Tare Weight

Step 1. Press the Down Arrow button until the cursor is in front of Tare Weight. The present

Tare Weight value is displayed.

Step 2. Press the Enter button. The Tare Weight Menu appears.

Step 3. Use the Left or Right Arrow buttons to move the cursor. When you have placed the

cursor in the location you want, use the up or down arrows to enter the number and decimal

point you want for this application. Repeat for the rest of the number locations.




Guidelines NOTE: If this value is exceeded by 5% a series of dashes ------- appear on the

front display. Communications to and from optional devices are not effected. This value is the

nominal operating capacity of the scale. The value you set should be the smaller value between

the capacity of the vessel (volume in gallons or Liters converted to weight in Lbs or Kgs) and

the combined weight capacity of the load cells (Lbs or Kgs).

Example: A vessel’s maximum capacity in volume is 200 gallons, in this case water. (One

gallon of water weighs approximately 8.54 lbs.) The weight will be 1,708.0 lbs. The combined

live load capacity of the load cells is 2,000 lbs. Select the lesser of the two values which in our

example is 1,708.0 lbs. Enter 1708.0.

Press enter to accept the current value or the CLEAR button to clear, and enter a new value.

The Scale Capacity Parameter is the total weight capacity of the scale system. If this value is

exceeded by 5% a series of dashes (------) will replace the weight display on the front

display. Communications to and from optional devices are not effected. This value is the

nominal maximum operating capacity of the scale.

The HI4050 Controller does not support peer to peer communications like the HI3000 series.

This ID will appear in the browser windows and diagnostics.



NOTE: Normally load cells are C2 capable if there are violet and gray wires. When all the

load cell wiring has been completed enter the C2 calibration menu and read the C2

information from the load cells. This C2 information is stored and retained for calibration

purposes and is read every time the calibration and diagnostics is run. If you are not reading

the correct number of load cells and the wiring is correct, look at the hardyinst.com web

support page under support and Web Tech Knowledge base for additional help or contact

Hardy Instruments Technical Support for additional aid.

For additional information consult the Technical manual. This manual is available on the

hardyinst.com web site under the products header and manuals.

Additional settings for time and date, time zones, EtherNet address setup and theory, user ID, serial

printer and scoreboard selections and operation. There is no bi-directional serial communications

available on the HI 3000 or HI4000 series controllers.

The calibration section covers C2 calibration and Traditional calibration.

Traditional calibration requires certified test weights. Traditional calibration is used in situation

where multiple scales must match exactly. C2 calibration does not verify the load cell performance

or if the scale is weight correctly. Always verify any calibration using certified test weights or

certified weight substitution.
