2.0 SYSTEM DESCRIPTION

This section of the manual describes the various operating features available for use in your installation.

2.1 AUTOMATIC ZERO MAINTENANCE (AZM)

The 8146 is equipped with an AZM feature. AZM is used to keep the instrument on zero in spite of small weight changes on the platform. AZM corrections operate at a rate of approximately one minor increment per second. The AZM range is selectable for either 2% or 10% of full scale capacity.

AZM may be disabled lin the setup procedure

2.2 NORMAL AND EXTENDED ZERO CAPTURE

The 8146 has a front mounted zero pushbutton which allows the operator to reset the scale to a zero condition. The normal range of the pushbutton is ±2% of full scale capacity. The 8146 permits increasing this capture range* to ± 20% full scale capacity.

The zero pushbutton may be disabled in the setup procedure.

NOTE: Increasing the zero capture range may conflict with Local and State Weights and Measures laws when the 8146 is installed in a “Legal for Trade” installation.

2.3 LOAD CELL EXCITATION (APPLICABLE WITH ANALOG PCB ONLY)

The 8146 uses gated 15 VDC excitation for normal analog load cell excitation.

Each Analog PCB is capable of powering six 350-ohm load cells; however, the 8146 will power a maximum of eighteen 350-ohm load cells per unit. Refer to the following chart for more information regarding the maximum number of load cells per unit.

The maximum distance between the 8146 and the load cells is 500 ft using 16-gauge or 300 ft using a 20gauge load cell cable.

Reduced excitation voltage levels are also available for use in hazardous areas. Refer to the following paragraph for a more detailed description of this reduced excitation voltage.

Per Analog PCB Per System

14-825 ohm cells 42-825 ohm cells

12-700 ohm cell 36-700 ohm cells 6-425 ohm cells 18-425 ohm cells 6-350 ohm cells 18-350 ohm cells 4-240 ohm cells 12-240 ohm cells

Page 9

2.4 REDUCED EXCITATION VOLTAGE (APPLICABLE WITH ANALOG PCB ONLY)

Reduced excitation output versions of the Model 8146 are available in all models for us with Toledo Intrinsic Safety Barriers. Contact Toledo Fast Factory for additional information. Reduced excitation voltage is limited to +3 volts for plus excitation and -3 volts for minus excitation (6 volts p to p). Also included in the reduced excitation voltage versions are sense-to-excitation-shunting resistors which prevent excitation runaway in the event that these line connections open.

NOTE: The lower excitation voltage must be considered when calculating the microvolt per increment

build. This also limits the maximum full scale increments to 40,000 instead of 50,000.

2.5 INITIAL AND SPAN (APPLICABLE WITH ANALOG PCB ONLY)

The initial and span values are calculated during the scale’s calibration procedure.

The initial range is from 0 to 27 millivolts.

The span range is from 3 to 45 millivolts, based upon 15-volt load cell excitation.

2.6 OVERCAPACITY

Individual Scales: The weight display will blank and printing is inhibited when the weight on the scale is five or more increments above full scale capacity.

Summed Scales: If any of the individual scales reach an overcapacity condition (as described above),

the summed display will show eight asterisks (SUM********lb). This display will also occur when

the summed total is greater than eight digits.

2.7 DIGITAL FILTERING

The 8146 is equipped with a multi-stage digital filter. By selecting the correct level of filtering required for your installation, changes in weight caused by wind, liquids, or vibration may be filtered out allowing the indication to stabilize.

As with all filtering, the higher the filtering rate the slower the display will respond to weight changes.

2.8 LINE SYNCHRONIZATION (LINE SYNC) (APPLICABLE WITH ANALOG PCB ONLY)

The line sync feature is used to eliminate any “crosstalk” on the load cell signal wires.

This “crosstalk” is typically caused by two or more load cell cables, operating at different frequencies, being run side by side, such as in conduit. This normally results in a slowly changing weight display.

The compensation for this is that all excitation voltages may be sync’d to the AC power source by means of line sync jumpers located on both the Analog PCB’s and the Power Supply PCB.

NOTE: Running load cell cable in a conduit with other cabling is not recommended.

Page 10

2.9 LINEARITY CONNECTION (APPLICABLE WITH ANALOG PCB ONLY)

The 8146 has the ability to compensate for nonlinear weight readings. This is done by taking weight readings at zero, half capacity, and full capacity. (Half capacity is defined as between 30 and 50% of full capacity.) It is important to note that the closer to full scale capacity the test weights are to the actual scale capacity, the more accurate the compensation will be.

Linearity correction may be disabled in the setup procedure.

2.10 ANALOG VERIFICATION

Analog verification is a test routine which is used to verify only the indicator’s electronic analog section. It is not usable on scales which have initial weight values greater than 7.5 millivolts. The AV test is performed automatically approximately every four hours with the display reading zero. The indicator will display “AAAAAA” during the test.

The AV process is performed by injecting a known test signal at the output of the pre-amp section. The resulting data is then compared to a value calculated during calibration. If the test data is within the tolerance of the calculated value (show in the chart), the test is passed. If the test fails, the indicator becomes inoperative until corrective action is taken.

Analog verification may be disabled in the setup procedure.

2.11 POWER UP SEQUENCE

When the AC power is applied, the 8146 will perform a series of display routines. These routines will check all display segments and inform the operator as to which software version he has and of any options that are installed. The series of display are as follows:

WEIGHT DISPLAY - Will count up, starting at 1 and ending at 0.

DATA DISPLAY - Will show a series of numbers and then flash the unit’s configuration.

EXAMPLE - Scales 2

3.3 DISPLAY FORMATS

3.3.1 Weight Displays

The weight display is a 7-digit vacuum fluorescent-type, 0.512 inches high with a lighted decimal point. A lighted comma may be selected to replace the decimal point by inserting a jumper plug across two pins located on the Weight Display PCB. (See Section 4.4.6.) The display also includes seven vacuum fluorescent descriptors which are located underneath the digits. These descriptors are ZERO, LB, KG, GROSS, NET, TARE, and SELECT. Their functions are as follows:

ZERO When illuminated, this indicates that the scale is on gross zero.

LB or KG Indicates the unit is in the pounds or kilogram mode.

GROSS When illuminated, this indicates that the displayed value is the gross weight.

Gross = Tare + Net

TARE When illuminated, this indicates that the displayed value is the tare weight.

Tare = Gross - Net

SELECT When illuminated, this indicates which scale has been selected for further operations.

The 8146 may have two Weight Display PCB’s installed -- with each Weight Display PCB having two 7digit displays. This allows the 8146 to display the weight on each of the four possible scales at the same time. With only two scales, it is possible to display the Gross or Net and Tare of each scale.

3.6 DATA INTERFACE

3.6.1 Printer Output

The 8146 is capable of transmitting bit serial, ASCII coded, data stream at 300 to 9600 baud. 20mA current loop, EIA RS232-C and EIA RS422 are all available as standard circuit types.

3.6.1.1 Demand Operation - 300 to 9600 baud

When a print command is received, either from the print key or an external “Print Demand” signal via the host port, the 8146 will transmit a message which was formatted during the printer output setup procedure. Transmission of a checksum character, as well as expanded print, is selectable in the same setup procedure.

3.6.1.2 Continuous Operation - 300 to 9600 baud

Setpoint status is transmitted via serial port in an ASCII coded format. This format is compatible with a Reliance Electric AUTOMATE 15 TM programmable controller. This allows a standard AUTOMATE 15 to be used as a setpoint output controller. Communications are via a standard ASCII RS232 serial link, at 9600 baud, 8 data bits, 1 stop, no parity into the programming port on the AUTOMATE 15. The first 12 bits in the first I/O rail [0.00 through 0.13 (octal)] are assigned to setpoint outputs 1-12. The last output rail (0.17) is assigned as a toggling watchdog bit, with state complimenting at each I/O update. The other bits in the rail (0.14, 0.15, and 0.16) are allocated, but of indeterminate state. The AUTOMATE 15 may be programmed to use the setpoint bits as internal points, but MUST NOT ALTER THE OUTPUT STATES. All other available I/O points (1.00 through 3.17) are usable to the AUTOMATE 15. Any digital output module usable with the standard AUTOMATE 15 head may be used for setpoint control. Automate head must have an address of 01, i.e., PCID = 1. Refer to Section 6.9 for a detailed description of this output.

3.6.3 Bar Code I/O - Optional

This port provides a bi-directional, bar code interface. 20ma current loop and EIA RS232-C circuit types are supported. Baud rates are selectable from 300 to 9600 baud. Refer to Section 6.8 for a more detailed description. Bar Code output is available for use with the 8860 Thermal Label Printer.

3.6.4 Computer I/O - Optional

This port provides a bi-directional interactive computer interface. EIA RS232-C and 20 mA Current Loop are available at 300 to 9600 baud. Refer to Section 6.7 for message format, content and protocol.

4.3 PRELIMINARY CALCULATIONS (APPLICABLE WITH ANALOG PCB ONLY)

Before connecting the 8146 to an understructure, it should be determined if the load cell(s) are of a size that will work correctly with the instrument and platform. If it is a standard build, proceed with installation of the scale. However, if it is a special build or a conversion of an existing mechanical scale, the microvolt per increment should be calculated. After calculating the microvolt per increment build, refer to the build charts to verify that the 8146 will operate correctly with this build.

4.3.1 To find the microvolt per increment build, you must first find the following items:

a) Scale capacity* b) Increment size * c) Number of load cells or total lever ratio d) Load cell capacity e) Load cell output rating in mV/V (millivolts per volt of excitation)

* in lb or kg depending on how the scale is to be calibrated and used.

4.3.2 Find the total load cell output in millivolts by multiplying the cell output rating* by the 8146

excitation voltage, 6 or 15 volts.*

NOTE: Toledo Scale load cells are 2mV/V. Other manufacturers’ load cells may be 1, 1.75, or

3mV/V. Standard excitation is 15 VDC, reduced excitation is 6 VDC.

4.3.3 Use the formula shown to calculate the microvolt per increment ratio.

IncrementSize TotalLoadCellOutput mV x LoadCellCapacityxNumberofCells orLeverRate

4.3.4 Divide scale capacity by the increment size to determine the number of increments which will be

used.

4.3.5 The following microvolt chart shows the limits, in microvolts, for the number of increments used.

1000

The 8146 Analog PCB’s are designed to operate with a maximum microvolt input of either 30 or 45uV*. This selection is determined by the position of the W3 jumper located on the Analog PCB. Verify the position of this jumper on all Analog PCB’s installed in your unit. It may be necessary to change this jumper position to reach an acceptable microvolt per increment build on your unit.

* The maximum microvolt input is found by multiplying the excitation times the millivolt output rating of the load cell.

5.0 PROGRAMMING PROCEDURE

This section of the manual describes the programming of the indicators’ operating modes and features as well as the self-calibrating procedure.

The procedure consists of two major groups which deal with the overall setup and calibration of the indicator. Each major group contains a description of the setup and calibration procedure. Section 5.1 details the procedure for the analog type units and Sections 5.2 thru 5.6 detail the procedure for the DigiTOL ® type units.

All question prompts and their current status, which affect the overall operation of the indicator, are displayed on the 16-character alphanumeric display. Questions which deal with the operation of a specific scale will be displayed on the associated scale’s weight display.

Five front panel keys are used throughout this procedure. The keys’ names and their functions are as follows:

KEY NAME DESCRIPTION

SETUP This key is used to enter into the setup procedure. It is also used to exit this procedure at

any point in the procedure except during calibration.

ZERO This key is used to back up to the previous question.

ENTER This is used to accept the currently displayed answer to the question prompt.

1 This key is used as a “YES” response to the question prompt and will enable the displayed

function.

0 This key is used as a “NO” response to the question prompt and will disable the displayed

function. It is also used to increment to the next possible selection if the question consists of several possible choices.

TO ENTER INTO THE SETUP PROCEDURE YOU MUST FIRST TURN “ON” THE SETUP LOCKOUT SWITCH(ES) -- (SWITCH “2” ON THE ADP-51, SWITCH “1” ON THE DWP-44) LOCATED ON THE SCALE CHANNEL PCB(S) OR THE DWP44 PCB(S). If there are two PCB’s installed in your unit, both switches must be turned “ON” to access the setup prompts. The ON position is when the switch handle is toward the J4 connector. (Switch “2” on the ADP-51, Switch “1” on the DWP-44).

The following chart can be used as a quick reference for programming descriptions. Also listed is the recommended selection for each step as a beginning point of initial setup. Verify each selection to be certain that it is correct for actual usage.

[Setup Scale X] SETUP/CALIBRATE SCALES?

This is the first prompt after entering the setup procedure and is displayed on the alphanumeric display. If you want to setup, calibrate or make any changes which deal with any one of the four possible scales connected, simply enter that scale’s number (1-4) and the routine will advance to F2.0. All prompts which deal with the selected scale will be displayed on that scale’s weight display. If you do not want to enter into this routine, enter a 0 and the procedure will skip to F5.0.

NOTE: This prompt will remain on the display throughout this routine. At the end of each scale’s

setup, the weight display will return to normal. At this time, the unit is asking for the next scale number or a 0 to continue. The routines that deal with each scale are: F2.0, F3.0, F4.0, and CAL.

0 To disable the front panel Zero pushbutton.

Page 37

[F4.4 ?} PUSHBUTTON ZERO CAPTURE RANGE

This prompt is requesting the percent of the scale capacity that can be captured by using the Zero pushbutton. This entry is selectable from 2 to 20% of scale capacity.

[F4.5 07] MOTION SENSITIVITY SELECTION

The detection of motion disables printing, tare, and pushbutton zeroing. Steps F4.5 and F4.6 program the sensitivity of motion detection. Changes in weight greater than F4.5 (minor increments) over the time required to perform F4.6 (A/D cycles) are detected as motion. The “in motion” signal is provided as a status bit in the output data when the continuous output mode is selected.

Sensitivity of motion is the amount of change in weight allowed before motion is detected.

The sensitivity can be programmed in a range from 0.1 to 3 major increments in steps 0.1 increment.

To determine what number to enter in this step, use the following procedure. Valid selections are 0* through 30 with 07 recommended as a beginning value.

* Determine the number of increments (or part of an increment) that the sensitivity should be. For example, 0.5, 1 or 0.7 increment. Multiply this number by 10. Example: If the number selected is 0.7, multiply this by 10 to get 7. This result (7) is the number to be entered for step F4.5.

NOTE: If a value of “0” is entered there will be no motion detection and prompt F4.6 will be skipped.

[F4.6 03] MOTION DETECTION RANGE

This step programs the number of A/.D cycles over which the 8146 will monitor weight changes. The changes in weight must be less than the value programmed in step F4.5 to obtain a “no motion” signal. Numeric values between 1 and 20 A/D cycles are selectable with a beginning value of 3 recommended. The “ENTER” key must be pressed to proceed to step F4.7.

NOTE(S): 1 The update rate of the 8146 (A/D cycles per second) is dependent upon the number of

full scale increments and the amount of initial weight. It varies from approximately 11 (at 1,000 total increments) to 4 (at 50,000 total increments).

2 The smaller this number is, the greater the probability will be for detecting “no motion”

since it checks for motion over a shorter length of time.

Page 38

[F4.7 1] DIGITAL FILTERING SELECTION

This allows selection of different quantities of A/D cycles to be filtered before a display update. The higher the number, the slower the update. Key in the appropriate selection from the chart below and then press “ENTER”.

FILTERING SELECTION FILTERING RATE

0 NONE 1 LIGHT 2 MEDIUM 3 HEAVY 4 VERY HEAVY

[f4.8 ?] ANALOG VERIFICATION. Press:

1 To enable analog verification.

0 To disable analog verification.

[CAL] ACCESS CALIBRATION MODE? Press:

1 To enter the calibration mode.

0 To skip the calibration mode. (The procedure will return to the Setup Scale prompt.)

NOTE: Error codes that may be displayed during calibration are described in the

troubleshooting section of this manual.

[C1 ] FULL SCALE CAPACITY [XXXXXX]

This display is showing yhou the programmed scale capacity. If this capacity is correct, press the “ENTER” Key.

If the displayed capacity is not correct for your scale, enter the desired scale capacity and press the “ENTER” Key.

[C2 ] INCREMENT SIZE [XXXXXX]

At this time the unit is asking you to enter the displayed increment size.

If the displayed increment size is not correct for your scale, enter the desired size and press the “ENTER” key. This entry must include the decimal point or trailing zero if required. Maximum increment size is 500.

Page 39

[C3 X] LINEARITY CORRECTION. Press:

1 To select the two-stage linearity correction

0 To disable the two-stage linearity correction.

NOTE: This step will normally not be required. If after calibration, the indication appears to

be nonlinear, this step may be used to correct this. The use of this step requires that test weights of 60% of the scale’s capacity be available for calibration.

[SC ] CALIBRATION SHORT CUT

This allows bypassing the actual test weight calibration by entering in previously calculated initial and span values. These values are determined AFTER the actual test weight calibration has been completed. To obtain these values, answer YES to the PRINT SETUP prompt at the end of the setup procedure. The initial and span values needed will be included in the printout of the setup parameters. Press:

1 If the short cut initial and span values are to be used for calibration, the standard test weight

calibration will be bypassed.

2 If the initial and span values are not to be used, the 8146 will proceed with the standard test

weight calibration procedure.

NOTE: At this time the calibration sequence will follow one of four possible procedures. The

procedure this sequence takes depends on how you answered the “Linearity Correction” and “Calibration Short Cut” prompts. Use the following chart to determine which procedure you should follow.

seconds. The weight display will then return to normal.

Page 42

where a “build-up” procedure is used for calibration. The procedure for using the span adjust feature is as follows.

5.1.2

Before span adjust can be used, the standard calibration, as specified in the setup section, must be performed. It is suggested that as much weight as is practical be used for calibration.

5.1.3

Apply known test weights to the scale. If any adjustment is necessary proceed to the next step.

5.1.4

Enter the setup procedure. Select the correct scale and advance to prompt F3.5. Change the setting of this prompt to a 1 (yes).

5.1.5

Exit the setup procedure.

5.1.6

Enter the setup procedure and select the correct scale. The data display will now show [Cal Adj 000000].

5.1.7

To make a span adjustment, enter the correct test weight value. Enter all digits including those to the right of the decimal point. (See Note c below.) Press the “ENTER” key and the normal setup procedure will begin.

5.1.8

Exit the setup procedure. The weight display should now show the correct weight value. This procedure may be repeated several times during a “build-up” calibration.

5.1.9

After all adjustments are completed. reenter the setup procedure and change prompt F3.5 to a 0 (NO). Exit the setup procedure. The indicator is now ready for normal operation.

Page 43

NOTES OF INTEREST:

a. This procedure will work correctly once when in the net mode. This is useful if a device to hold the

test weights is required. Simply attach the holding device, then press Tare. Add the test weights, then follow the span adjustment procedure. After one adjustment, tare must be cleared and then reentered if required again.

b. Weights that are entered in values other than multiples of the increment size will not be accepted. For

example, entering the 103 pounds when the increment size is 2 lbs.

c. The entire weight value must be entered including numbers to the right of the decimal point. This is

different from the standard calibration where only the numbers to the left of the decimal point may be entered.

5.4 SETUP AND CALIBRATION PROCEDURE FOR T-LAN MULTIPLE DIGITAL LOAD CELL SYSTEMS

This procedure describes the setup and calibration for digital load cell(s) which are interfaced to the 8146 via a T-LAN network.

5.4.1 Access Load Type Selection Group 00

[00 ]

With the display prompt at [-- ], enter 00 followed by pressing the “ENTER” key to select GROUP 00 setup parameters. The display will increment to parameter 01.

[01 ] DLC TYPE SELECTION

0 - Single DLC 1 - Power Cells 2 - DigiTOL ®

The selection entered for scale One will be forced into the scale Two parameters and this step will be skipped when setting up scale Two.

Press “1” to select the T-LAN network configuration.

NOTE: If this parameter is being changed from 0 to 1, the indicator must be powered down then back up

after group 00 parameters have been set before continuing with calibration so DWP44 card and the 8146 CPU will get initialized properly for the type of operation selected.

[02 ] LOAD CELL OPERATION

This parameter selects whether the load cells are to operate independently or in sectional pairs. The independent mode is intended for applications such as tank or hopper scales where there is an odd number of load cells connected, or floor scales where corner adjustments will be made. The sectional pair mode is intended for applications such as floor and truck scales where section adjustments are made. For the load cells to operate in the sectional pair mode, an even number of load cells must be used.

0 - Independent cell operation 1 - Sectional pair operation

[03 ] NUMBER OF LOAD CELLS

Enter the number of load cells to be addressed for the scale being calibrated. (i.e., if calibrating scale 1, enter the number of load cells in scale 1.) If independent cell operation was selected, then only numbers from 1 to 16 will be accepted. If sectional pair operation was selected, then only even numbers from 2 to 24 will be accepted.

Page 48

[04 ] LOAD CELL ADDRESS ASSIGNMENT

This parameter is used to access the auto addressing procedure. The auto addressing procedure. The auto addressing procedure is used at initial installation to assign individual addresses to each load cell. If a load cell is being replaced, or a load cell is being added to or removed from a scale, use the procedure outlined in parameter group 90.

0 - Skip to parameter 05 1 - Proceed with auto addressing of load cells

NOTE: If scale 2 is being addressed, the system starts the addressing at address 25 minus the number

of load cells in scale 2. This forces the last address to be 24, allowing modifications to scale 1 without having to reassign addresses to scale 2.

If addressing scale 1, disconnect the interface cable to scale 2 from the auxiliary power supply. Leaving the cable connected without proper termination will cause communications interference with scale 1. If addressing scale 2, the interface cable to scale 1 does not need to be disconnected if scale 1 has been addressed already.

For the auto addressing procedure to work properly, all of the load cells must have an address of 240 (factory setting). For scales operating in the sectional pair mode, addressing must be arranged with odd addresses on one side, and even addresses on the other side as show below.

1 3 5 7 9 11

2 4 6 8 10 12

A) When the auto addressing procedure is selected, the power to the load cells is turned off, the

display will show [04 XX], where XX is the number of the load cell already addressed and then [Add XX], where XX is the address to be assigned to the next load cell. Connect the load cell to be addressed, then press the “ENTER” key. Power to the load cells will be turned back on and the address will be sent to the load cell. Power to the load cells will then be turned off.

B) Connect the next load cell to be addressed, then repeat Step A.

If the auto addressing is successful, the display will keep advancing to the next address. If the last load cell has been addressed, the display will advance to parameter [05 ] (if addressing scale 1) or return to the [-- ] prompt.

If a communications error occurs during the attempt to auto address, an [E8 XX] error code will be displayed. If a communications error occurs, check the following:

1) Make sure address XX is the address of the load cell the operator was addressing. If not, the

“ENTER” key may have been pressed more than once. The DWP44 card may have successfully addressed the load cell, then proceeded to address the next load cell. Press the “CLEAR” key to acknowledge the error. The display will return to the [04 XX] prompt. Connect the load cell to be addressed, then proceed to step A.

2) The load cell may not be set to the factory address (240). If this is the case, press the “ZERO”

key until you are back to the [-- ] prompt. Then proceed to group 90 to manually readdress the load cells.

3) There could be a wiring problem between the pit power supply and the load cell.

4) The load cell being addressed may be bad.

Page 49

5) If no communications are successful to any of the load cells, the auxiliary power supply or the pit

supply may be bad. Also check for wiring problems. Refer to the troubleshooting section for more details.

NOTE: If this parameter is changed, the indicator must be powered down then back up after group 00

parameters have been set before continuing with calibration so the DWP44 card and the 8146 CPU get initialized properly for the type of operation selected.

5.4.2 Access Calibration Sequence Group 10

The display will count down from [ 16 CAL] to [09 CAL]. A check is now made to see if enough counts are received from the DLC. If not, new T0 and T1 values are calculated and sent to the DLC. The display will then continue to count down to [01 CAL].

If new T0 and T1 counts where sent, then the display will show [E SCL], otherwise it will proceed to calibration done. Remove the test weight from the scale and press the “ENTER” key. The display will count down from [16 CAL] to [01 CAL].

When calibration is completed, the display will show [CAL d] for two seconds indicating that the zero and span calibration has been successfully completed. The display will then return to the [--] prompt.

5.4.3 Access Load Cell Replacement Group 90

[90 ]

With the display prompt at [-- ], enter “90” followed by pressing the “ENTER” key to select Group 90 calibration parameters. Parameters 91 - 93 will be prompted in sequence. All other parameters in this group must be accessed individually.

Page 51

[91 ] RE-ADDRESSING OF A LOAD CELL

This parameter allows you to readdress or manually address a load cell. This procedure may be required if replacing a load cell in an existing scale, or if the auto addressing procedure fails due to a load cell not having the factory address of 240.

It is important to note that only one cell at a time may be connected to the network when using parameter 91 to readdress a load cell. When two scale platforms are connected to one DWP44 card the cells share the same network; therefore, all cells on both scales must be disconnected, except for the single cell that is being readdressed.

0 - Skip re-addressing procedure. 1 - Access re-addressing procedure

A) The display will show [LC OFF] indicating that power to the load cells has been turned off.

Disconnect all of the load cells from the pit power supply except for the load cell to be re-addressed.

B) Enter the desired address followed by the “ENTER” key. Entering an address of 00 will set the load

cells address to the factory setting of 240.

C) If the re-addressing is successful, the display will show [LC OFF] indicating that the power supplies

to the load cells have been turned off. Reconnect the other load cells then press the “ENTER” key. Power to the load cells will be turned back on.

If a communications error occurs during the attempt to re-address the load cell, an [E8 XX] error code will be displayed. Pressing the “CLEAR” key will return you to the [-- ] prompt. Refer to the troubleshooting section for more details.

[92 ] REPLACING A LOAD CELL

This parameter allows for the replacement of a bad load cell with a new one. For this procedure to work, the load cell being installed must have the factory set address of 240. The DWP44 card will look for a response from each of the load cells it is set up to address to determine which load cell is missing. It will then look for the new load cell by addressing the load cell address 240. The missing address will be given to the new load cell. The new cell or section that the new cell was placed in must now be shift adjusted via Parameter 93 or by performing a complete calibration procedure. The scale must also be rezeroed and re-spanned.

0 - To skip to Parameter 93 1 - to proceed with load cell replacement

A) The display will show [LC OFF] indicating that power to the load cells has been turned off.

Disconnect the load cell being replaced and connect the new one on.

B) Press the “ENTER” key. Power to the load cells will be turned on and the DWP44 will automatically

identify the missing load cell, then re-assign that address to the new load cell.

If this procedure doesn’t work, the load cell may need to be re-addressed to the factory address of 240 as detailed in Parameter 91.

Page 52

[93 ] SHIFT ADJUSTMENT OF A CELL OR SECTION

This parameter allows for shift adjustment of a single load cell or section without having to perform the shift adjustment for the entire scale.

0 - To skip the Parameter 94 1 - To proceed with manual shift adjustment

A) The display will show [CELL ] if operating in the independent mode, or [SEC ] if operating in the

sectional pair mode. Enter the cell or section to be adjusted followed by the “ENTER” key.

B) The display will show [LOAD XX] where the XX is the cell or section number. Place the test load on

the scale as close to the cell or section as possible then press the “ENTER” key. The display will count down from [16 CAL] to [01 CAL].

C) The display will show [LOAD XX] where XX is the cell or section number. Place the test load on the

scale as close to the cell or section as possible then press the “ENTER” key. The display will count down from [16 CAL] to [01 CAL].

D) The display will show [LOAD XX]. Move the test load as close to the cell or section as possible then

press the “ENTER” key. The display will count down from [16 CAL] to [01 CAL].

E) The display will advance to Parameter 94 or return to the [-- ] prompt.

[94 ] SET SHIFT CONSTANTS TO 1

This parameter allows you to temporarily set all of the shift constants to 1. This allows you to see what the weight readings from individual cell or sections are without any compensation. When this parameter is set to 1, the shift constants will be set to 1 only until the unit is powered down. Once powered down then back up, the stored shift constants will be used. This parameter is automatically set to 0 upon entry into calibration (Parameter 19).

0 - Use shift constants calculated during calibration

1 - Set shift constants to 1 until power down or until re-entry into calibration mode.

[95 ] EXPANDED DISPLAY MODE

This parameter selects whether the weight will be displayed in normal calibrated increments or minor increments.

0 - Display weight in calibrated increments

1 - Display weight in minor increments

Page 53

[96 ] MANUAL SHIFT ADJUST

This parameter allows for manual shift adjustment of individual load cells or sections. This parameter differs from Parameter 93 in that this procedure allows you to adjust the cell or section to a specific weight value. When performing the manual shift adjustment, the weight will be displayed in an expanded mode to provide for finer adjustment to the shift constant.

0 - To return to [-- ] prompt 1 - To proceed with manual shift adjustment

A) Put the test load over the cell or section to be adjusted.

B) The display will show the weight in an expanded mode. Record this number as it will be entered for

[LOAD b] later in this procedure. Press the “ENTER” key.

C) The display will show [ CELL ] or [ SEC ], depending on how parameter 02 has been set

(independent cell or sectional pair operation). Key in the number of the cell or section to be adjusted and then press the “ENTER:” key

D) The display will show [ LOAD A ] for approximately one second and then go blank. Key in the

weight value of the test load, then press the “ENTER” key.

E) The display will show [ LOAD b] for approximately one second and then go blank. Key in the

number recorded in Step B, then press the “ENTER” key.

F) The display will now show the adjusted expanded weight value. If the number shown was higher or

lower than the desired weight, it will be necessary to make another pass at the adjustment. Press the “ENTER” key to return to the [ CELL ] O R [ SEC ] prompt, step C.

If the number shown represents the correct weight, press the “CLEAR” key to advance to the [ SA ] prompt. Pressing the “1” key will save the new shift constants. Pressing the “0” key will leave the shift constants unchanged. If the number shown is incorrect, another pass at the adjustment will be necessary. See the below listed example for details.

NOTE: Entering a “1” in response to the [ SA ] prompt will erase the original shift constants and store

the new shift constants. The scale MUST be re-calibrated using parameter 19.

EXAMPLE:

The following example illustrates parameter 96 being used to adjust a two section truck scale platform that has a 40 lb shift error between sections. Section one being the lighter section, and using a 10000 lb test load.

A) Insure a good Zero and then place the 10000 lb test load as close to the center of section one as

possible. Enable parameter 96 [96 1 ].

B) The display will show the weight in an expanded mode. For example [ 9962 ].

Record this number and then press the “ENTER” key.

C) The display will show [ SEC ]. Key in the number “1” for section one.

D) The display will show [ LOAD A] for approximately one second and then go blank. Key in “10000”

for the test load weight value, and then press the “ENTER” key.

E) The display will show [ LOAD b ] for approximately one second then go blank. Key in the number

recorded in step B, “9962” and then press the “ENTER” key.

F) The display will now show the adjusted expanded weight. For this example let us say that

Page 54

this value is [ 9988 ]. Since section one is still weighing light, another pass at the adjustment will be necessary.

Pressing the “ENTER” key will return the display to the [ SEC ] prompt. Key in a “1” for section one, and then press the “ENTER” key. On this pass a higher value must be entered for [ LOAD A]. Key in “10010”, for example, and press the “ENTER” key. Since [ LOAD b ] was entered previously it is not necessary to enter is again, simply press the “ENTER” key after the [ LOAD b ] prompt is displayed. This time let us say the displayed weight value is correct, [ 10000 ]. Press the “CLEAR” key to advance to the [ SA ] prompt. Press the “1” key to save the new shift constant.

Several iterations may be required to attain the desired weight value. Remember that re-calibration must be performed whenever the shift constants are changed.

If an error is made while making an entry for [ LOAD A ] or [ LOAD b ], pressing the “CLEAR” key will clear the display, to allow re-entry of data. To return to the previous prompt, press the ZERO” key. Pressing the “CLEAR” key while at the expand weight display will advance to the [ SA ] prompt.

[97 ] DISPLAY AND ENTRY OF SPAN, ZERO AND SHIFT CONSTANTS

This parameter allows the operator to view or alter the values stored for span, zero and shift constant for each load cell or section.

0 - To return to [-- ] prompt 1 - To proceed with display of these values

A) The display will show [97A ] for 1/2 second, then display the current span value. Press the “ENTER”

key to retain the current value or enter a new value followed by pressing the “ENTER” key.

B) The display will show [97b ] for 1/2 second, then display the current zero value. Press the “ENTER”

key to retain the current value or enter a new value followed by pressing the “ENTER” key.

C) The display will show [CELL XX] or [SEC XX] for 1/2 second, then display the current shift constant

for cell or section XX. Press the “ENTER” key to retain the current value or enter a new value followed by the “ENTER” key.

D) Press the “ENTER” key to display the next cell or section values. If the last cell or section was just

displayed, the display will show [SA ]. If you want to save the new values permanently, press the “1” key. The original values will be replaced by the new ones. If you want to return to the original values, press the “0” key. The display will return to the [-- ] prompt.

Page 55

[99 ] DISPLAY LOAD CELL OUTPUT

This parameter allows the operator to see the raw count output from each load cell. This value does not directly correspond to the displayed weight.

0 - To return to the [-- ] prompt 1 - To proceed with viewing the load cell output

A) The display will show [99 ]. Enter the address of the load cell that you want to view followed by the

6.2 PRINTER OUTPUT DESCRIPTION - I/O #1

6.2.1 Channel Characteristics

6.2.1.1 Physical Characteristics:

The printer port supports XON - XOFF protocol on the receive line in 20mA, RS232, or RS422 modes. The RS232-C interface supports a CTS input and a DTR output (always ON). See Section 4.4.1 for Jumper W3 to make CTS active.

6.2.1.2 Data Characteristics:

Each character is ASCII codes (hex) and is 11 bits in length. The character bit frame consists of 1 start bit 7 data bits, 1 even parity bit and 2 stop bits. This character frame is fixed and cannot be changed.

Transmission baud rates (under program control) are selectable for either 300, 1200, 2400, 4800 or 9600.

Data transmissions may operate in either the demand mode, where the unit requires a print command to initiate a single transmission, or in the continuous mode, where a data transmission occurs at a program selected output rate.

A checksum character is selectable (during setup) for output in the transmission. If checksum is selected an STX character, including the STX and CR characters. Bit 8 of this character is parity.

6.3 DEMAND MODE OUTPUT

This output is used to transmit the operator defined data fields, in the format programmed, one time for each print command received. Refer to Paragraph 6.5 of this section for a detailed description of the user defined format.

6.3.1 Note(s) Of Interest

• Depression of the print key or a remote print command (from Host Port) causes data from the

scale that is currently selected to be transmitted one time.

• Scales programmed for lb/kg switching will apply leading zero suppression up to 1 digit to the left

of the decimal point. If no decimal point is programmed, it will be assumed to be in the far right position of the weight value. When switched to the lb mode, the symbol “lb” will be printed after the weight value and the decimal point will be printed as “.”. When switched to the kg mode, the symbol “kg” will be printed after the weight value and the decimal point will be printed as a comma.

• Scales programmed as metric only will not apply leading zero suppression and the symbol “kg”

will be printed after the weight value. The decimal point will be printed as a comma. When a tare value is entered, the letter “h” will be printed after the “TR” symbol and the letter “c” will be printed after the “NET” symbol to indicate the hand entered tare value.

• The start of text character (STX) is only included in the transmission if checksum is enabled.

6.4 CONTINUOUS MODE OUTPUT

The output format is designed to transmit all 17 characters (18 checksum is selected) at a program selected output rate.

The format consists of three status bytes, the gross or net weight value and the tare weight value (if a tare has been taken), along with the STX and CR characters. The three status bytes are used to transmit certain setup and operating parameters of the indicator. (Refer to Paragraph 6.4.1 of this section for a more detailed description).

The transmitted weight value may be, depending upon the program selection, either a specific single scale programmed to always be transmitted or the currently selected scale, etc. See printer setup parameter F5.9 for available selections.

6.5 USER DEFINED PRINT FORMAT

The user defined ticket format is designed to permit the user the option of selecting the data field and the location on the ticket at which he wants this field printed.

There are two types of data fields available for selection: (1) Constants - which are predefined text strings, and (2) Variables - which are data fields controlled or changed by the 8146 operation (such as weight values, time, date, consecutive number, selected scale, etc.).

Each of the available constants and variables are assigned a data code. (Refer to the following chart.) These codes are entered during the ticket configuration routine in the setup procedure. The same codes are used for both ticket and Bar Code printer output.

When a print command is received, the printout routine searches for all data fields programmed for printing on the first line. After finding all programmed fields, the data is then sent to the printer along with the necessary control characters for expanded printing, if selected. This procedure is then repeated for all programmed lines. After all lines are printed, the 8146 will then transmit the programmed number of line feed characters, causing the printer to advance the ticket one line for each line feed character is receives.

6.7.2 Operation Description

The 8146 responds as a polled device (slave) to the host (master) device. Under no circumstances will the 8146 transmit data without a request from the host to do so. Each scale is assigned a unique single digit address number. This number corresponds to the scale’s display number and is used to designate one scale from the others in the 8146. The address numbers for the 8146 are 1 through 4, with “0” reserved for non-scale specific functions transmitted by the host.

There are two types of transmitted data packets which may occur between the host and the indicator:

(1) DOWNLOAD. In this type of transmission the host sends a data packet to the indicator

with the direction byte of “D” (44H). The indicator will then act on the received data as

determined by the function code. The host does not expect a response from the indicator.

(2) UPLOAD. In this type of transmission the host sends a data packet to the indicator with

the direction byte of “U” (55H). The indicator will then act on the received data packet as

determined by the function code and transmit the requested data to the host.

Each transmission is complete, there is no additional ACK/NAK scheme required. The indicator performs no data checking on the data received (except for checksum validation if selected.) It is the responsibility of the host to ensure that the data is correct. If data checking is required, the host must request back the data which was just downloaded to the indicator.

NOTE: The 8146 host communications interface incorporates a message timer that will timeout if the

message terminator (<CR>) is not received within 200 ms after receiving the message start character (<STX>). The message will be ignored on a timeout error.

6.7.3 Data Packet Format

All transmission sent by the host must be in the following format. (All transmission sset by the 8146 will be in this same format.)

Where:

<STX> = ASCII Start of Text Character, 1 byte, (2H) <ADD> = Device address number, 1 byte <DIR> = Direction of data: “D” = download, (44H)

“U” = upload, 1 byte, (55H)

<FTC> = Function Code, Refer to Function Code Chart for listing,

1 byte [data] = Optional data field, variable length <CR> = ASCII Carriage Return character, 1 byte, (0DH) <CKSUM> = Optional Checksum Character, 1 byte

The function code included in the transmitted data packet determines what action the indicator will take. The various function codes are listed in the following chart. Included in this chart are the directions which each function may take. After determining which function you want, refer to the Function Code Description section for a more detailed description of that function.

Page 91

EXAMPLE: To request the displayed weight data from scale #1 the following string (checksum disabled)

would be sent):

<STX> 1UB <CR> or in hexadecimal 02H, 31H, 55H, 42H, 0DH

The 8146 will respond with:

<STX> 1 UB <SP> 00849 <CR> or in hexadecimal 02H, 31H, 55H, 42H, 20H, 30H, 30H, 38H, 34H, 39H, 0DH

Displayed weight shows [0084.9]

6.7.4 Function Code Descriptions

Certain functions are described in the following pages to help explain how they operate. Unless noted in the description of a particular function code, it may be assumed that either leading spaces or zeros may be used to fill the required character length for that function code data field.

NOTE: Function codes are expressed as the hexadecimal representation of the equivalent ASCII

character. For example, function code 41H (Hex) would be represented as the ASCII character upper case “A”. Refer to section 8.3 for the ASCII code chart. See example under function code 43H.

6.7.4.1 Code 41H (All Functions):

This is used to request all information contained in all function codes at one time. The response from the 8146 will contain this data in the order listed below:

Function 42H, 43H, 44H, 45H, 49H, 4AH, 46H, 47H, 50H, 51H, 4CH

Page 92

6.7.4.2 Code 42H (Displayed Weight):

This is an upload function only, permitting the host to request the displayed weight from the indicator. Upon receiving this function code, the indicator will respond by sending a complete data packet to the host. This packet will have the displayed weight installed in the data field. No decimal point is included. It is the responsibility of the host to install the decimal point, if needed, into this value.

6.7.4.3 Code 43H (Gross Weight):

This is an upload function only, permitting the host to request the gross weight from the indicator. Upon receiving this function code, the indicator will respond by sending a complete data packet to the host. This packet will have the gross weight installed in the data field. No decimal point is included. It is the responsibility of the host to install the decimal point, if needed, into this value.

EXAMPLE: To request the gross weight data to be sent for scale nmber 1, the following string (checksum disabled) would be sent.

or in Hexadecimal: 02H, 31H, 55H, 43H, 0DH

6.7.4.4 Code 44H (Tare Weight)

This function can be used in both the upload and download transmission. Its function is to permit the host to request the current tare value or to send a tare value to the indicator. The tare value, sent by the host, must be 6 bytes in length. Leading zeros (30H) must be used to fulfill this 6 byte requirement if the actual tare value is less than 6 digits. The indicator does not send or expect to receive a decimal point in the tare value. In the upload operation it is the responsibility of the host to install the decimal point, if needed, into this value. In the download operation, the decimal point location, if used, is assumed by the setup of the indicator. This function will operate within the indicator’s operational parameters selected during setup (i.e., tare interlock, autoclear).

6.7.4.5 Code 45H (Net Weight):

This is an upload function only. Its purpose is to permit the host to request the net weight from the indicator. Upon receiving this function code, the indicator will respond by sending a complete data packet to the host. This packet will have the net weight installed in the data field. No decimal point is included. It is the responsibility of the host to install the decimal point, if needed, into this value.

6.7.4.6 Code 46H (Time and Date):

This information can be requested from or sent to the 8146. The data field must be 16 continuous bytes and in the same format as selected in the setup procedure at prompt F5.6. Except that the time field will proceed the date field in all cases. Spaces will not be accepted; zeros must be used.

Page 93

6.7.4.7 Code 47H (Next Consecutive Number):

This function can be used in both the upload and download transmissions. Its purpose is to allow the host to send a new, or request the current, 9 digit consecutive number (CN). Leading zeros (30H) are required to fulfill this 9 digit requirement. In a download transmission, the host must include the new CN in the data field. In the upload transmission the host would not send the CN data. Upon receiving this function code, the indicator will respond by sending a complete data packet, including the current CN data, to the host.

6.7.4.8 Code 48H ( Clear Last Printed Data):

This command will clear the print buffer (or the I/O printer port) of all data. The buffer will then be filled with all spaces. The last printed data may be requested by using function code 51H.

6.7.4.9 Code 49H (Status Bytes):

This function is an upload only: that is, the host may request certain information from the 8146 such as setup parameters. No data may be changed using this function.

6.7.4.11 Code 4BH (Control Byte):

This function code is a download only. Its purpose is to permit the host to transmit a control byte to the indicator. This control byte must be installed in the data field of the transmitted data packet and may be used to initiate one of the six possible commands that the 8146 can act upon. These six commands and their assigned bits are listed below.

BIT 0 Print Command .... ASCII “A” - 41H

BIT 1 Switch to lb Mode ... ASCII “B” - 42H BIT 2 Switch to kg Mode ... ASCII “D” - 44H BIT 3 Clear Tare Command . ASCII “H” - 48H BIT 4 Auto Tare Command ... ASCII “P” - 50H BIT 5 Zero Command . . . ASCII “‘“ - 60H BIT 6 See Note BIT 7 Parity

NOTE: Bit 6 is not used as a command, but is required to complete the 7 data bits required/. This bit

must always be set to 1.

To initiate the command, simply set the appropriate bit to 1, while leaving the remaining five bits at 0. Only one command may be initiated at any one time. If more than one is required the entire function code must be retransmitted. All commands are subject to the indicator’s operational parameters (i.e., no printing with motion, lb/kg switching disabled, etc.)

6.7.4.12 Code 4Ch (Setpoint Data):

This function may be used in both the upload and download transmission. Its purpose is to allow the host to send a new, or request the current setpoint number and its numeric value.

For downloads, the transmission format is as follows:

<STX> <ADD> <DIR> <4C> NNSSSSSSS <CR> <CKSUM>

Page 98

Where:

<STX> = ASCII Start of Text Character, 1 byte <ADD> = Device address number, 1 byte <DIR> = Direction of data: “D” = download, 1 byte <4X> = Function code for setpoints <NN> = Is the two byte setpoint number (01-12) <SSSSSSS> = SSSSSSS is the right justified setpoint with leading

zeros (M.S.D. is a space unless unit is configured

as “SUM-ONLY” mode). <CR> = ASCII Carriage Return Character, 1 byte <CKSUM> = Optional Checksum Character, 1 byte

For Uploads, the transmissions format is as follows:

Where:

<STX> = ASCII Start of Text Character, 1 byte <ADD> = Device address number, 1 byte <DIR> = Direction of data: “U” = upload, 1 byte <4C> = Function code for setpoints <NN> = Is the two byte setpoint number (01-12) <CR> = ASCII Carriage Return Character, 1 byte <CKSUM> = Optional Checksum Character, 1 byte

6.7.4.13 Code 50H (ID Number):

This function may be used in both the upload and download transmission. Its purpose is to allow the host to send a new, or request the current 3 character ID field. Leading zero’s (30H) are required to fulfill this 3 character requirement. In a download transmission, the host must include the new ID in the data field. In the upload transmission, the host would not send this data. Upon receiving this function code, the indicator will respond by sending a complete data packet, including the Current ID in the data field.

6.7.4.14 Code 51H (Last Printed Data):

This function is an upload function only. Its purpose is to permit the host to request the contents of the print buffer. Refer to the following chart for the actual contents of this buffer.

6.8 BAR CODE INTERFACE DESCRIPTION - I/O #2 (OPTIONAL)

6.8.1 Channel Characteristics

6.8.1.1 Physical Characteristics

The bar code input/output serial port is designed to support the EIA RS232-C (with CTS handshaking) and the 20 milliamp current loop types.

6.8.1.2 Data Characteristics

Each character is ASCII coded and is 9 to 11 bits in length [dependent upon stop bit(s) and parity bit selections]. The character bit frame consists of: 1 start bit, 7 data bits and 1 or 2 stop bit(s). The parity bit may be programmed as one of the following: (1) even parity, (2) odd parity, or (3) no parity bit.

Transmission baud rates are selectable for either 300, 1200, 2400, 4800, or 9600 baud.

6.8.2 Bar Code Input Description

The bar code input interface is a bit serial EIA RS232-C link. This will allow a standalone bar code reader to be connected to the input.

This option allows the entry of bar encoded tare weight and/or numeric ID data.

The use of the bar code input is complementary to, and does not inhibit, the normal keyboard tare and ID entry functions. Once the input data is received, the indicator will treat this data exactly as if it were entered from the keyboard. A decimal point need not be included in this data. If included, the decimal precision may not exceed the decimal precision of the indicator. If no decimal point is included in the data, the programmed decimal point position will be assumed. Tare data must also match the indicator’s displayed increment size. Data which does not meet these requirements will be ignored.

Programming selections are used to select whether the input data is to include the tare and/or ID data and also whether this data is in a single or multi-line format. Refer to the following paragraphs for a more detailed description of these two formats.

6.8.2.1 Single Line Format:

This format is used when all data is being sent to the indicator in a single line. The tare and ID fields must be a fixed length. (This length is selectable in the programming setup procedure and must be followed with an ASCII carriage return (CR) character.) Leading zeros are significant. In this format, field identifying characters are not required.

SINGLE LINE FORMAT CHART

ttttttiii CR

Where:

tttttt = Tare weight data iii = ID data CR = Carriage Return (ASCII)

6.8.2.2 Multi-line Format:

This format is used when each data field is transmitted on separate lines. In this mode each line must begin with a single field identifying character (selectable via the programming setup procedure) followed by the data field and ending with an ASCII carriage return (CR) character. In this format the data field length is variable and is limited only by the maximum number of keyboard entries (i.e., tare is 6 digits maximum, and ID 3 characters maximum). A typical example might be:

MULTILINE FORMAT CHART

pIII CR Ttttt CR

Where:

P = Field Identifier iii = ID data T = Tare field identifier tttt = Tare data CR = Carriage Return (ASCII)
