Description The HI 2151/30WC is a compact, multipurpose, microprocessor-based

weight controller (See Fig. 1-1) that is used for a wide variety of process weighing applications, including batching, blending, check weighing, filling/dispensing, force measurement, level by weight, and weight rate monitoring. As a standalone product, the HI 2151/30WC can control as many as eight set point relays, and transmit data via analog, serial and BCD communications. The weight controller can also be

1-1

HI 2151/30WC MANUAL

used as a front end for a control system, transmitting weight values via a standard operator-selectable serial port (RS-232, RS-422/485) to programmable logic controllers (PLC's), computers, and printers.

Data is displayed alpha-numerically on the six-digit, fourteen segment LED display and graphically on the 30-segment bar-graph display. Weight values can be based on either net, gross, Rate-of-Change (ROC), peak hold or totalized weight values in pounds or kilograms.

An optional Allen Bradley Remote I/O and PROFIBUS interface is available for communication to programmable logic controllers. The weight controller’s 20-bit, analog-to-digital converter updates twenty times per second and is capable of 985,000 counts of display resolution. This provides enough resolution for accurate weight measurement and enough control to tolerate large “dead” loads and over sizing of load cells/sensors. Users can enter commands either from the communication ports or locally from a sixteen-button, front-panel keypad. A portion of the keys can be locked out to limit operator access and protect data. A limited number of commands can be entered through a rear Remote Functions connector.

WAVERSAVER

Typically, mechanical noise from other machinery in a plant environment exists in all industrial weight control and measurement applica-

tions. WA VERSAVER® enables the weight controller to distinguish t he actual weight data from the mechanical noise that comes in on the load

cell signal. WAVERSAVER® can be configured from the front panel to ignore noise with frequencies as low as 0.25 Hz. Users can select one of four higher additional cut-off frequencies to provide a faster instrument response time. The default factory configuration is 0.50 Hz vibration frequency immunity.

Calibration C2 second-generation electronic calibration can calibrate a scale sys-

tem without using certified test weights. A C2 weighing system consists of up to eight load sensors, a junction box, interconnect cable and an instrument with C2 capabilities, such as the HI 2151/30WC. Each Hardy Instruments C2-certified load sensor sends a distinct digital signal that the HI 2151/30WC uses to calculate weight and count the number of sensors in the system. To factor in any known weight on the scale, the user enters a reference value from the front panel. (A zero reference value indicates there is no weight on the scale.)

The instrument is also capable of performing traditional calibration such as with the use of certified test weights.

INTEGRATED TECHNICIAN™ is a built-in diagnostics utility that continuously monitors the system and allows the operator to rapidly troubleshoot problems from the front panel. Adding an optional an IT junction box extends the diagnostics capability to any load sensor.

Chapter 1 - Overview

Excitation Monitor Continuously monitors the system excitation current for evidence of

open or shorted load sensors or damaged or broken excitation wire(s), including the wires between the instrument and the junction box. If the measured current deviates from a ± 10% tolerance, an "ERRExC" (Error Excitation) displays on the front panel. In a system with C2 load sensors, IT computes the correct current and displays alarms if the initial measured current is out of tolerance. Without C2 load sensors, the initial read is assumed to be correct and is used as the standard.

Digital Volt Meter (DVM)

The DVM displays millivolts (mV to one digit to the right of the decimal point) and millivolts per volt (mV/V to four digits to the right of the decimal point) for both the whole system and individual load sensors. The DVM helps enables the user to isolate a faulty component from the front panel. The voltage reading can be used to level a balanced system and to make corner adjustments to platform scales. Accuracy is ± 2% or better of full scale.

Return to Zero Test This test compares the original voltage reading saved at calibration

against the current voltage reading of an empty vessel and displays either a pass (OK) or fail (ERR) message. The test checks for load sensor damage (due to electrical zero shift or abnormal mechanical forces) that causes binding sensors in the system.

• With an IT junction box, the test will pass or fail the individual load

sensors providing a true fault isolation capability.

• Without an IT junction box, the test will pass or fail on the basis of

a cumulative reading rather than an individual reading of each load sensor.

Weighing System Tests (Requires the IT Junction Box) This test does the following analysis to

diagnose drifting or unstable weight reading problems:

Secure Memory Module (SMM)

1. It disconnects the controller and engages an internal reference signal to see if the problem is within the instrument.

2. It disconnects the load sensors and engages an internal (in the junction box) reference signal to see if the cable between the instrument and the Junction Box is causing the problem.

3. It reads the weight of each load sensor to see if a load sensor might be causing the problem.

Weight readings from the individual load sensors makes this test useful for making cornering, leveling, and load-sharing adjustments.

The Secure Memory Module stores critical HI 2151/30WC configuration, calibration and setup data (excluding Peak Hold) and protects it from corruption. When a new parameter is entered during system operation, the SMM automatically updates that value in its memory. Since the SMM is conveniently accessible from the instruments rear panel, data stored in one HI 2151/30WC may be restored to the new instrument by physically transferring the SMM.

1-3

HI 2151/30WC MANUAL

NOTE: The SMM is lim ited to 1,000,000 lift-time write functions. A write is performed after

any parameter change to the calibration, zero, and tare functions.

NOTE: You cannot transfer the SMM from the HI 2151/30WC to the HI 2151/20WC.

Set PointRelays The HI 2151/30WC is fitted with two standard, internal, selectable and

mechanical form C (SPDT) relays. Six optional, external, solid-state relays are available and are field configurable as form A or B types. Both types have individual set point, preact, and deadband parameters. Each can be programmed to respond to the standard Net or Gross modes of operation or the optional ROC, Totalizer or Peak Hold modes. These relays can be used to open or close valves or gates or to turn motors, mixers, vibration equipment, heaters, coolers, etc. on or off.

Serial Port One standard serial port can be configured to receive commands and

transmit weight data to a serial device such as a printer output or bidirectional port. By resetting jumpers within the instrument, it can be configured for RS 232 (-A1), RS 422 (-A2) or RS 485 (-A3). Baud rates are user selectable at 600, 1200, 2400, 4800, 9600 or 19,200.

Hardy Link LAN The Hardy Link Local Area Network (LAN) assigns an address to each

instrument and provides the firmware necessary to handle in-coming and out-going communications.

Remote Functions Rear panel input of a level or momentary grounding that can be used to:

Tare the instrument., activate a print sequence, totalize the display, force the Net mode, toggle between pounds or kilograms, initiate the optional ROC (Rate-of-Change) mode, freeze the front panel display or one of the communications ports, and clear the totalizer or peak hold values. This is useful for adding large additional industrialized switches to the control panel.

Auto Zero Tracking Auto Zero Tracking causes the display to indicate zero as long as any

"live weight" on the scale is below the set zero tolerance and the scale is not in motion. This capability allows the instrument to ignore material build-up in the weigh system within the set zero tolerance.

NOTE:

Do not use auto zero tracking to correct a drifting-scale problem. Auto zero tracking will zero and write to the SMM every second if there is a change in weight. A correct graduation size is requir ed to stop excessive weight changes and r educe write commands to the SMM. See Chapter Six for graduation size setup guidelines.

The amount of weight zeroed off is cumulative. The autozero command will fail if the current gross weight plus any previously zeroed amount exceeds the zero tolerance.

1-4

Auto Zero Tracking is enabled when switch eight of S3 (the configuration dipswitch), labeled Config on the instrument's rear panel is in the on position.

Chapter 1 - Overview

Output Device Options

Analog Output (-B1) Analog Output is configured from the front panel or the serial port and

set up by jumpers on the printed circuit card. The option allows the transmission of Gross, Net, Optional ROC, Peak or Total weight as 05V, 0-10V, 0-20mA or 4-20mA (or the reverse of these) and makes it possible to span these ranges over a portion of the weight data. Resolution is either 16,000 counts or the number of display counts available in the range selected, whichever is less. Two analog optional boards can be installed in each instrument. Both voltage and current data are available simultaneously.

Binary Coded Decimal (BCD) Output (-B2)

Binary Coded Decimal (BCD) Output (-B5)

BCD Single Termination Card (B6)

BCD Quad Termination Card (B7)

This BCD Option provides six digits of parallel weight data representing Net, Gross, Tare and the present front panel display. If all types of output data are requested, they appear one after the other, ten milliseconds apart. The BCD option provides a 37-pin, D-subminiature connector on a 6-inch cable.

This BCD option provides six digits of parallel weight data representing Net, Gross, T are and The Present Front Panel Display . If all types of output data are requested, they appear one after the other, ten milliseconds apart. The BCD option provides a 40-pin connector on a 60-inch cable for use with either the optional -B6 or -B7 external termination boards.

The BCD Single Termination Card is an optional external interface point for a single BCD port signal line. The card is designed for use with a single HI-2151/30WC-B5 instrument.

The BCD Quad T ermination Card is an optional external interface point for up to four sets of BCD port signal lines. All terminal positions accept 20- to 26-gauge cable sizes. Additional terminal boards may be interconnected to allow multiple BCD ports to exist in a tri-state arrangement.

Remote I/O (RIO) Interface to the AllenBradley Network (B8)

Binary Coded Decimal (BCD) Output (-B9)

The RIO port allows bi-directional communications with Allen-Bradley Programmable Logic Controllers (PLC) and Small Logic Controllers (SLC). Supporting up to 230.4 Kbaud transfer rates and both discrete and block data transfers, the HI 2151/30WC represents a quarter rack of discrete I/O (32 bits in the Logic Controllers output and input image files) to the Logic Controller.

This option provides six digits of parallel weight data representing Net, Gross, Tare and the present front panel display. If all types of output data are requested, they appear one after the other, ten milliseconds apart. This option provides a 24-inch cable for use with the HI 2151/ 30WC-WS wall mount controller.

Control Options

Peak Hold (-C1) This option is generally used in testing to determine peak forces a prod-

uct or material can withstand. It can also be used to track the highest force applied to the scale. It displays and stores the highest gross weight value measured until that value is cleared by a command from the front panel key pad or a remote source.

Rate-of-Change (ROC) (-C2)

The ROC option measures and displays the rate at which a material enters or is dispensed from the scale over a period of time. The register for ROC holds 21 entries. New weight values are input to the register at the rate of 1/20th of the time base. The first register is subtracted from the 21st Register, which is one tim e base older than the 1st register . The time frame can be set to units per second, minute or hour. A time base of discrete values is selectable from 1 to 1800.

Set Point Options

TTL(Transistor Transistor Logic) Level Output (-D1)

External Setpoint Relays Card (-D2)

WARNING DO NOT OPERA TE WITH INCORRECT LINE VOLTAGE. TO DO SO WILL

RESULT IN PROPERTY DAMAGE OR PERSONAL INJURY. CHANGING THE INPUT VOLTAGE RATING BETWEEN 120 AND 240 VAC REQUIRES MODIFICATIONS TO THE POWER/RELAY CIRCUIT BOARD AND RELAY OUTPUT BOARD. THIS PROCEDURE SHOULD ONLY BE DONE BY AUTHORIZED PERSONNEL. FOR FURTHER ASSISTANCE CONTACT HARDY INSTRUMENTS, CUSTOMER SUPPORT.

Step 1. The HI 2151/30WC is factory configured to operate from

either 120 or 240 VAC, 50 or 60 Hz power. Check the model number of your unit to verify the voltage. If the unit is configured for 240 VAC, an "E2" will be printed on the name plate.

Step 2. The power and relay circuit card filters and conditions AC

power. However, for noisy power lines, external conditioning may be required. Contact Hardy Instruments Customer Support for more information.

Step 3. The AC power should be supplied by a "clean" primary line,

directly from the power panel. This line should not supply any other equipment, including the feeding unit, and should be supplied with a minimum 10 amp breaker.

Step 4. T o connect power to the controller, install a 3-wire, minimum

of a 14 AWG power line to the 3-pin terminal block connector. (See Fig. 3-8)

Load Cell/Point Connections (J1)

About Load Cell Wiring

The unit is capable of powering a maximum of eight 350 ohm load cells/points. If more than eight load cells/points are used, an external power supply is required. Figures 3-9, 3-10, Load cell/point connections (J1) shows how to connect a full six-wire hookup, a four-wire hookup, and an external excitation supply. Load cell/point cables are connected to J1 through a furnished mating plug, P1.

NOTE: Contact Har dy C ustomer Sup port f or ins tallat ion inform ation when us ing an extern al

power supply.

To ensure a "clean" signal from the load cells/points, follow these precautions :

• Load cell/point cables MUST be run separate from all other cables

and in their own conduit. Load cell/point cable shield should be attached to ground screw on rear panel only.

• Six-wire, shielded load cell/point cable should be used for lengths

of 50 feet or more or if intrinsic safety barriers are used. Eight-wire shielded cable, preferably Hardy C2 cable, must be used for C2 calibration.

• A void load cell/point cable splices. If cables are longer than needed,

coil up and tape excess cable. If cables are short, use an appropriate junction box. When terminal lugs are installed on load cell/point cables, Hardy Instruments recommends the lug be crimped and soldered.

• When connecting the HI 2151/30WC weight controller to the HI

215IT junction box using C2 load cell/point cable (6020-0001), use the following color code:

BCD Menu Setup Procedures

About BCD Communication (See Section 4 for Configuration Procedures)

The BCD option board provides parallel output of a sensed gross, net, or tare weight. The BCD option is setup by first entering the Option Menu and selecting the FORMAT menu.

The menu display shows a combination of GNTDP (G = gross, n = net, T = tare, D = display, P = print).

BCD Print • The weight select mode tells the output device which type

of data is present.

• The user selects which type of data is desired by toggling

"GNT" under the Option/BCD sub-menu.

• If all three types of data are requested, then all three will

appear on the output one after the other, 10 milliseconds apart.

• If "D" is selected, the output will follow the mode being dis-

played.

Setup Procedures Step 1. Press the 7/Option key . This gives the user access to the Setup

Sub-Menu. ROC or another option displays.

NOTE: The display may show an option other than "ROC", depending upon which options

were installed. The HI 2151/30WC will show the first available option, in our example, ROC.

Step 2. Press the up or down arrow until the sub-menu BCD P1

appears. Step 3. Press the Enter Button, the FORMAT sub menu appears. Step 4. Press Enter. A series of letters (GNTDP) and spaces appear.

For example: G N _ _ D P . Note that in our example the “T” is

not displayed and that there are 6 spaces total. The sixth

value is used in other communication protocols.

Serial Port Menu Setup Procedure (See Chapter 4 for Configuration Procedures)

• The standard serial port is setup through the option menu and is

identified as SER P1.

• The following is a brief description of each parameter, followed by

details on menu operation.

DISPLAY MEANING

SERCON Serial port configuration. The port can be used as

either a print output port or as a bi-directional communication port.

BAUD Baud rate selection. The baud rates that can be

selected are: 1200, 2400, 9600, or 19,200.

PARITY Parity selection for transmission error detection.

Allows parity to be set at even, odd, or no parity.

STOPS Stop bit selection. Sets number of bits used to

indicate end of a transmission frame. The number of stop bits can be set to 1 or 2.

LENGTH Word length selection. Sets the number bits for each

data word. Word length can be set to 7 or 8 bits.

FORMAT Formats the serial data output. To configure the

output use the left arrow button to select the code letter corresponding to the specific parameter(s). When the lett er is flash ing use the up or down arrow buttons to toggle the code letter on the display. To enable a specific parameter, the code letter must be shown on the display. Pressing the -/Test/Clr button will restore all code letters. The codes are:

G Gross Weight N Net Weight T Tare Value R Rate of Change (ROC) S Set point, Deadband, Preact Values

5-9

HI 2151/30WC MANUA L

DISPLAY MEANING

PRINT Selects print mode. P sets print trigger and "-" sets

continuous output.

BI-DIR Selects bi-directional mode. The bi-directional

codes are:

A Altered print (removes checksums) P Bi-directional with print trigger

- Bi-directional without print trigger.

ADDRESS Selects the instrument address. This is a two digit

value, being 01 to 99.

ECHO Selects whether instrument commands are returned

or displayed. Echo can be turned on or off. If the (bi-directional only) Echo is turned on, commands sent to the instrument are returned. If turned off, only data transmitted from the instrument will be displayed.

CONTRL Selects hardware and software handshaking

control. The hardware mode controls Request to Send (RTS) lines. In this mode the receiving device must set Clear to Send (CTS) lines to high to enable transmission. The software mode controls the transmission by the following control codes:

XOFF - (CTRL-S) halt transmission XON - (CTRL-Q) resume transmission

When a serial port is configured for bi-directional communication with a Print Trigger format, the control port will respond to the remote function print or serial print command just like a print port.

Serial Procedures

NOTE: If you have a problem with weight readings not changing or not being able to exit

from a menu, check to see that the instrument has not been set in the Display Hold mode by a serial command. A C H (change hold) command will tog gle bet w een Hold and Unhold. There is no visual indication showing the present mode.

Analog Output Setup Procedures (Option)

About Analog Output (See Chapter 4 for Configuration Procedures)

The analog output option allows the user not only to output gross, net, ROC, Peak, or total weight as 0-5V, 0-10V, 0-20 mA or 4-20 mA (or the reverse of these via the front panel), but makes it possible to span these ranges over a portion of the weight data. A full analog output is obtained over the range desired. Resolution of the analog out is 16,000 counts, or the number of display counts available in the range selected, whichever is less. All of this is accomplished via the front panel or the serial port. Two analog option boards may be installed in each unit.

CHAPTER 6 - CALIBRATION

Chapter 6 covers calibration procedures for the HI 2151/30WC weight controller. Users and service personnel should be familiar with these procedures before installing or operating the HI2151/30WC.

For the weight controller to work properly , it must be calibrat ed prior to operation. We also recommend that the instrument be re-calibrated periodically or when not in use for extended periods. Be sure to follow the procedures completely to ensure that the weights read by the controller are accurate.

All calibration should be done in the Gross mode.

Pre-Calibration Procedures

Chapter 6 - Calibration

Mechanical Check Procedures

Step 1. Check to determine if the load cells have been installed prop-

erly.

• Refer to your load cell I&M manual for proper installation instructions.

• On some single and double ended shear beam load cells there is an arrow (↓) that indicates the direction of the applied load. If the arrow is pointing in the wrong direction, change the position of the load cell so that it is mounted in the direction of the applied load.

Step 2. Check for Binding on the Load Cell or other parts of the sys-

tem.

CAUTION BINDING ON A SCALE/VESSEL OR LOAD CELL DOES NOT ALLOW THE

LOAD CELL FREE VERTICAL MOVEMENT AND MAY PREVENT THE INSTRUMENT FROM RETURNING TO THE ORIGINAL ZERO REFERENCE POINT.

• A load cell must be mounted in such a way that 100% of the load (Vessel w/Contents) is vertically passed through a load cell. (See Fig. 6-1)

• Check to see that nothing is binding the load cell. This means that nothing is draped across the scale/vessel or the load cell, such as a hose, electrical cord, tubes, or other objects.

Step 3. Check to see that nothing is coming in contact with the scale/

vessel other than service wires and piping that have been properly mounted with flexible connectors.

Step 1. Check to see that there is power to the controller.

• If there is power to the controller The front panel display should be lit.

• If an error message (ERREXC) appears in the display, it means there is a problem in the system. See Troubleshooting Chapter 8 for corrective action.

• If the display appears with a value the unit is ready for calibration.

Step 2. Typical Load Cell/Point Input/Output Measurements (EXC &

SIG Outputs)

• The HI 2151/30WC is designed to supply 5 vdc excitation to as many as eight 350 ohm load cells/points.

MI LLIVOLTS DC

DEAD LOAD 500# ZERO REFERENCE POINT

MAXIMUM LOAD CAPACITY

• The expected output from each load cell/point depends on the mV/V rating of the load cell/point and weight.

• For example, a 2 mV/V load cell/point will respond with a maximum of 10 mVDC at full weight capacity of the system which includes the weight of the vessel and the weight of the product as measured by the load cell/point.

• If the load cell/point weight capacity is rated at 1000 pounds, the load cell/point output will be 10 mVdc at 1000 pounds, 7.5 mVdc at 750 pounds, 5 mVdc at 500 pounds and so on.

• A zero reference point will vary from system to system depending on the "Dead Load" of the vessel. "Dead Load" is the weight of the vessel and appurtenances only, with no product loaded. In our example we will assume the dead load to be 500 lbs. (See Fig. 6-2)

FIG. 6-2 MILLIVOLTS/WEIGHT SCALE

• Based on the example, the operating range for this scale is 5-10 mVdc with a 500 pound weight range. Understand that after zeroing the instrument, the 0 reading on the instrument refers to the zero reference point and not absolute 0 mVdc or absolute 0 weight.

NOTE: Load cell/point measurements are checked with a digital volt meter at the summing

junction box or the J1 connector on the rear panel of the HI 2151/30WC or use Integrated Technician. if using the IT Junction Box.

Bar Graph The Bar Graph function displays in graphical form

the value of the mode (Total, Gross, Net, ROC, Peak) selected in the bar graph setup menu.

NOTE: The bar graph mode and the display mode are totally independent. Make sure you

know what mode each are in before reading.

Load Check Step 1. Place a load (weight) on the scale or vessel.

Step 2. Check to see if the weight reading changes on the display in

the proper direction.

• e.g. if the display reads 100 pounds and a 20 pound load is placed on the vessel or scale, the display should read 120 or some value over 100.

• If the display reads 80 pounds and a 20 pound load is placed on the vessel or scale, the reading is going in the wrong direction and indicates a problem. (See the Chapter 8, Troubleshooting for corrective action.)

• If the display is reading improperly or shows no change, something is wrong either with the setup or configuration.

Step 3. If the display changes in the proper direction, remove the

weight and proceed to calibrate the controller.

Step 4. The unit of measure is selected and will be the basis for all set

points.

Step 5. "DECPNT" appears on the display.

NOTE: The displayed unit of measur e can be ch anged during nor mal operation. However, all

internal calculations use the unit of measure selected during calibration.

Setting the Standard Decimal Point (DECPNT)

This parameter sets the number of decimal places to use in weight values (Total weight may be set to a different number of decimal places).

Step 1. To determine the highest recommended decimal point, divide

the total load cell capacity by 10,000, and use the number of decimal places in your answer as a reference. For example: 10,000 EU scale divided by 10,000 = 1, no decimal point is recommended. 100 EU load cell capacity divided by 10,000 = .01, requiring two decimal points or less is recommended.

Step 2. Press the Enter button. Six number eights (88888.8) are dis-

played.

Step 3. To select the decimal point location, push the left arrow ←

until the decimal point is in the correct position. The decimal point will wrap from left to right.

HI 2151/30WC MANUAL

Step 1. If the optional weight totalizer is installed, TOT DP appears

on the display.

Step 2. Press the Enter button. There are six number eights 888888

displayed.

Step 3. To select the decimal point location, push the left arrow ←

until the decimal point is in the correct position. The decimal point will wrap from left to right.

Step 4. Press the Enter button to accept the decimal location, The

Motion T olerance sub-menu MOTION appears on the display.

Setting the Motion Tolerance Value (MOTION)

Step 1. The base motion number can be calculated by using the fol-

lowing formula:

Base Motion Number = Total Load Cell Capacity/10,000 x 3

NOTE: Motion Tolerance must be greater than or equal to the Graduation Sizes. Recommen-

dation would be thr ee gr adu at ion si z e s.

Step 2. The motion tolerance is the t olera nc e value used to dete rmine

if the scale is in motion.

Step 3. The controller displays the MOTION LED when a change in

the displayed (averaged) reading is outside the value entered. Step 4. Default value is 3 units of measure. Step 5. Press the -/Test/Clr button to clear the current value. Step 6. Use the numeric keys to type in the new tolerance value. Step 7. Press Enter. The Graduation Size GRAD is displayed.

Setting the Graduation Size (GRAD)

The graduation size sets the minimum increment the instrument will compute and display. The Base Graduation Number is calculated by dividing the total load cell capacity by 10,000. For example: With two decimal points selected, the graduation size 10 will display increments of .10 engineering units. With two decimals points selected, the graduation size 50 will display increments of .50 engineering units.

NOTE: If you undersize your graduation setting to increase display resolution, do not use

auto zero tracking. This combination will damage the SMM due to excessive write operations.

6-8

Step 1. Press the Enter button. The graduation size 20 appears on the

display with the zero flashing. Step 2. There are nine graduation size selection options:

150 2 100 5 200 10 500 20

Chapter 6 - Calibration

Step 3. To select one of the sizes, use the up arrow ↑ or down arrow

↓ keys to scroll through the selections.

Step 4. The graduation size is recalculated each time the instrument is

calibrated for span.

Step 5. Press Enter to accept the selection. The Zero Tolerance

(OTOL) sub-menu appears on the display.

Setting the Zero Tolerance (0 TOL)

NOTE

Setting The Auto Zero Tolerance (A0 TOT)

This sets a weight limit for an operator adjusting the weight of an empty scale using the upper left ZERO push button. This value is the zero tracking window and reflects an amount of weight differential of an empty scale. Normally, a Zero Tolerance amount equal to 2% of the total load cell capacity is acceptable. The default zero tolerance is 10 units of measure (10 is displayed). The maximum Zero Tolerance number that can be entered is 32766.

The amount of weight zeroed off is cumulative. The zero command will fail if the current

gross weight plus any previously zeroed amount exceeds the zero tolerance.

Step 1. Press the Enter button. The default display will appear (10) or

the previous set value (10). Step 2. Press the -/Test/Clr button to clear the current value Step 3. Use the numeric keys to enter the new value. Step 4. Press the Enter button to accept the new value. Zero Tolerance

sub-menu (O TOT) appears on the display. This parameter sets a weight limit that applies when the Auto Zero

Tracking feature (0 TRK) or a communication command adjusts an empty scale. When 0 TRK is enabled, the display is reset to zero when the weight is within the set limits and not in motion.When the Auto Zero T olerance (0 TOT) is enabled (Set Dip Switch #8, See Chapter 4), any weight within the set zero tolerance limit will cause the display to automatically read zero when the scale is not in motion.

NOTES:

Normally an acceptable Zero Tolerance amount is less than or equal to

1.5% of the total load cell capacity. The default auto zero tolerance is 10 units of measure, and the maximum number you can enter is 32766.

Incorrect graduation size or a drifting scale with auto zero tracking enabled can damage the SMM.

The amount of weight zeroed off is cumulative. The autozero command will fail if the current gross weight plus any previously zeroed amount exceeds the zero tolerance.

Step 1. Press the Enter button. The default display will appear (10) or

the previous set value. Step 2. Press the -/Test/Clr button to clear the current value Step 3. Use the numeric keys to enter the new value. Step 4. Press the Enter button to accept the new value.

6-9

HI 2151/30WC MANUAL

Step 5. If the value does not exceed the maximum zero tolerance

value or is not a negative value, the screen will accept the new value.

Step 6. If the value exceeds the maximum zero tolera nce value or is a

negative number, an ERR 15 is displayed. You need to change the value to meet the requirements in step "3". Go to step 4 and repeat steps 4, 5 & 6 to enter new values until the value meets the requirements in Step 3.

Step 7. Press the Enter button to accept the new value. "AVRAGE"

sub-menu appears.

NOTE: Weight can accumulate up to the value entered for the Auto Zero Toler ance and the

instrument will automatically display a 0.

Setting the Number of Readings Averaged (AVRAGE)

Step 1. This setting is to aid in ignoring the effects of material impact.

If material is not entering or exiting the scale evenly, necessary weight fluctuations can be seen. Averages also contribute 50 ms each 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. This sets the number of weight readings that will be used to compute the displayed weight. The average is a sliding average so that a new average is available for display at every reading.

Step 2. This sets the number of weight readings whic h will be use d to

compute the displayed weight.

Step 3. The average is a sliding average so that a new average is

available for display at every reading. Step 4. The default number of readings per average is 10. Step 5. Press the Enter button. Step 6. Use the numeric keys to enter the new value in the range of 1

to 200. (If you enter a number greater than 200 or a negative

number, the ERR 3 statement will appear .) Press the -/Test/Clr

button. Enter a new number.

Setting the Scale Capacity (SC CAP)

6-10

Step 7. Press the Enter button. The Scale Capacity (SC CAP) sub-

menu appears. Step 1. If this value is exceeded by 5% an HI indication appears 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 small

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). Step 2. The value you set should be the smaller value between the

capacity of the vessel (volume in gallons or Liters converted

For example: A vessel's capacity in volume is 2,000 gallons, in this case water. (One gallon of water weighs approximately

8.54 lbs.) The weight will be 17,080 lbs. The combined live load capacity of the load cells is 20,000 lbs. Select the lesser of the two values which in our example is 17,080 lbs. Enter 17,080.

Step 3. Press the Enter button. The WAVERSAVER® (WVRSVR)

sub-menu appears.

Step 1. 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 1-3 for low amplitude high frequency vibrations. Use WAVERSAVER settings 3-5 for high

amplitude low frequency vibrations. Step 2. Press the Enter button. Step 3. A value appears. The Default setting is 4. Step 4. There are 5 selectable levels. 1 provides the least vibration

immunity with the fastest response time, and 5 provides the

Soft Calibration Procedures for Single Load Cell/Point Systems

NOTE: Soft Calibration for systems with mor e than one load cell/point contact: Hardy Instru-

ments Inc., Customer Support Department.

About Soft Calibration

• Soft-Cal is a procedure that quickly calibrates a scale system, on-

site, without test weights, material substitution or forced calibration.

• The process uses the certified, full scale mV/V output (sensitivity

and range) of each load cell.

• The full scale mV/V output of each load cell is mathematically

combined with a measured reference point, usually but not always zero, to calibrate the scale.

• The full scale mV/V data is on the calibration certificate which is

shipped with every Hardy load cell.

• The process assumes a consistent center of gravity on the scale with

even distribution.

6-15

HI 2151/30WC MANUAL

• All load cells must be correctly installed with no binding of any kind on the scale.

• You must use the same length cable as supplied with the load cell.

DO NOT CUT THE CABLE!!!

• A multiple load cell system, using a junction box, all balance potentiometer and resistors must be zero.

NOTE: For multiple load cell systems contact your local dealer or Hardy Instruments, Cus-

tomer Support Department.

• The Soft-Cal menu cannot be entered while in the National Bureau of Standards (NBS) mode.

Measure UNIT Sub-menu appears. Step 2. Press the down arrow ↓ until the CAL Sub-Menu appears. Step 3. Press the Enter button. The Hard Calibration HD CAL Sub-

Menu appears. Step 4. Press the down arrow ↓ until the Soft Cali bration S C AL Sub-

Menu displays. Step 5. Press Enter. The Sensitivity Sub-Menu SNSTVY appears.

Step 1. Use the numeric keys and enter the load cell full scale output

in mV/V found on the load cell calibration certificate. Step 2. You must enter five digits. If a load cell is listed at less than

five digits, add 0's to make up the five digit number. For

example: When the full scale output in mV/V is "2.99". You

need to enter the number as "29900". The least significant

numbers are on the right when looking at the display. Step 3. When multiple load cells are used, contact Hardy Instruments

Customer Service Department to compute the system total

full scale output sensitivity. Step 4. Press Enter. The Scale Range sub-menu RANGE appears.

Setting the Scale Range (RANGE)

Step 1. Press the Enter button. Step 2. Use the numeric keys and enter the sum of the rated capacities

of all load cells being used. An example: There are 3 load

cells rated at 1,000 lbs capacity each. The value to enter is

3000.

Step 3. Press the Enter button. The Reference Point Sub-Menu REF

PT appears.

NOTE: For HI 2151/20WC users the next setting would normally be the sticker value. The

sticker value for the HI 2151/30WC is entered at the factory and cannot be changed. Therefore it is not necessary to set the sticker value in Soft Cal.

Setting Resistance Baseline for Excitation Monitor

Quick C2® Calibration Procedures

About Quick C2 Calibration

1. C2 Load Cells

If C2 load cells are used in the weight control system, the controller calculates the resistance value during power up and turns on the excitation monitor.

2. Non C2 Load Cells

If Non C2 Load Cells are used in the weight control system, the controller will capture the resistance value when performing the Hard Calibration when setting the Zero Calibration Value.

The quick C2 calibration should be used when the controller has already been properly calibrated and when the system is determined to be slightly out of specification, for a scheduled periodic calibration.

• The Quick C2 calibration procedures do not replace the regular C2 calibration procedures.
