1.1 Operating Modes

The Tra cer AV has three modes of operation:

Normal (Primary) mode

Normal mode is the default mode of the Tra ce r AV . The indicator displays gross or net weights as required, using the LED annunciators described in Section 1.3 on page 2 to indicate scale status and the type of weight value displayed. Once configuration is complete and a legal seal is affixed, this is the primary mode in which the

Tra ce r AV can operate.

Setup mode

Most of the procedures described in this manual require the Tra cer AV to be in setup mode, including configuration and calibration.

To enter setup mode, remove the setup switch access screw on the Once the screw is removed, use a small screwdriver or pen tip to press the setup switch. The display changes to show the word

Test mode

1.3 LED Annunciators

The Tra ce r AV display uses a set of six LED annunciators to provide additional information about the value being displayed:

•

Gross and Net annunciators are lit to show whether the displayed weight is a gross or net weight.

• Center of zero ( ): Gross weight is within 0.25 graduations of zero. This annunciator lights when the scale is zeroed.

• Standstill ( ): Scale is at standstill or within the specified motion band. Some operations, including tare functions and printing, can only be done when the standstill symbol is shown.

•

lb and kg annunciators indicate the units associated with the displayed value: lb=pounds, kg=kilograms.

Digital outputs are typically used to control relays that drive other equipment. In the

Tra ce r AV , the setpoint value

will cause the display to flash. Outputs are designed to sink not source, switching current. Each output is a normally open connector circuit, capable of sinking 250 mA when active. Digital outputs are wired to switch relays when the digital output is active (low, 0 VDC) with reference to 5 VDC supply. LEDs on the CPU board light when the digital outputs are active.

2.4 Board Removal

If you must remove the Tracer AV CPU board, use the following procedure:

• Use a wrist strap to ground yourself and protect components from electrostatic discharge (ESD) when working inside the

Tra ce r AV enclosure.

• This unit uses line fusing which could create an electric shock hazard. Procedures requiring work inside the

Tra cer AV enclosure must be performed by qualified service personnel only.

• The supply cord serves as the main power disconnect for the

Tra cer AV. The power outlet must be

installed near the unit and be easily accessible.

1. Disconnect power to the

Tra ce r AV .

2. Cut security cable (if installed) and remove screws.

3. Remove the top cover.

4. Disconnect power supply cable from connector J7 on the

Tra ce r AV CPU board.

5. Unplug connectors J1 (load cell cable), J2 (digital inputs), J3 (EDP), J4 (serial), J6 (digital outputs), and J2 (display). See Figure 2-4 5 for connector locations.

6. Remove the five screws from the CPU board, then lift the board out of the enclosure.

To replace the CPU board, reverse the above procedure.

Description

Sets the level, in display divisions, at which scale motion is detected. If motion is not detected for 1 second or more, the standstill symbol lights. Some operations, including print, tare, and zero, require the scale to be at standstill. Maximum legal value varies depending on local regulations.

If this parameter is set to 0, the standstill annunciator will be set continuously on, and operations including zero, print, and tare will be performed regardless of scale motion. If 0 is selected, ZTRKBND must also be set to 0.

Overload. Determines the point at which the display blanks and an out-of-range error message is displayed. Maximum legal value varies depending on local regulations.

Sample rate. Selects measurement rate, in samples per second, of the analog-to-digital converter. Lower sample rate values provide greater signal noise immunity.

Digital filtering. Selects the digital filtering rate used to reduce the effects of mechanical vibration from the immediate area of the scale.

Choices indicate the number of A/D conversions that are averaged to obtain the displayed reading. A higher number gives a more accurate display by minimizing the effect of a few noisy readings, but slows down the settling rate of the indicator. See Section 6.6 on page 37 for more information on digital filtering.

Digital filter cutout sensitivity. Specifies the number of consecutive readings that must fall outside the filter threshold (DFTHRH parameter) before digital filtering is suspended. If NONE is selected, the filter is always enabled.

Digital filter cutout threshold. Specifies the filter threshold, in display divisions. When a specified number of consecutive scale readings (DFSENS parameter) fall outside of this threshold, digital filtering is suspended. If NONE is selected, the filter is always enabled.

Tare function. Enables or disables push-button and keyed tares. Possible values are:

BOTH:Both push-button and keyed tares are enabled NOTARE:No tare allowed (gross mode only) PBTARE:Push-button tares enabled KEYED:Keyed tare enabled

4.5 More About Calibration

The following topics provide additional information about compensating for environmental factors (Section 4.5.1) and diagnostic information for determining expected zero and span coefficients.

4.5.1 Adjusting Final Calibration

Calibration may be affected by environmental factors including wind, vibration, and angular loading. For example, if the scale is calibrated with 1000 lb, a strain test may determine that at 2000 lb the calibration is 3 lb high. In this case, final calibration can be adjusted by tweaking WVAL to 998.5 lb. This adjustment provides a linear correction of 1.5 lb per 1000 lb.

To adjust the final calibration, return to the prompt and press Zero to show the test weight value. Press

Units to adjust calibration up or down.

Press Zero to save the value, then press return to the CALIBR menu.

4.5.2 A/D Counts

Table 4-3 list s the ideal A/D counts that result from input signals of 0–3.0 mV with zero deadload. Actual values will typically be higher than the values shown in Table 4-3, but the ideal values can be used when calibrating the

Tra cer AV with no attached scale.

5.0 EDP Commands

The Tracer AV can be controlled by a personal computer or remote keyboard connected to the EDP port. Control is provided by a set of EDP commands that can simulate front panel key press functions, display and change setup parameters, and perform reporting functions. The EDP port provides the capability to print configuration data or to save that data to an attached personal computer. This section describes the EDP command set and procedures for saving and transferring data using the EDP port.

5.1 The EDP Command Set

The EDP command set can be divided into five groups: key press commands, reporting commands, the RESETCONFIGURATION special function command, parameter setting commands, and transmit weight data commands.

When the responds with the message verifies that the command was received and has been executed. If the command is unrecognized or cannot be executed, the indicator responds with

The following sections list the commands and command syntax used for each of these groups.

5.1.1 Key Press Commands

Key press EDP commands (see Table 5-1) simulate pressing the keys on the 2-button keypad. Most commands can be used in both setup and weighing mode. Several of the commands serve as “pseudo” keys, providing functions that are not represented by a key on the front panel.

For example, to enter a 15-pound tare weight using EDP commands:

status. See Section 6.2 on page 33 for more information.

Table 5-12 on page 30 for information about the SX and EX commands.

Table 5-2. EDP Reporting Commands

The RESETCONFIGURATION command can be used to restore all configuration parameters to their default values. Before issuing this command, the

Tra ce r AV

must be placed in test mode (press and hold setup switch for approximately three seconds to show TEST menu).

This command is equivalent to using the DEFLT function on the TEST menu. See Section 6.7 on page 39 for more information about test mode and using the TEST menu.

NOTE: All load cell calibration settings are lost when the RESETCONFIGURATION command is run.

5.1.4 Parameter Setting Commands

Parameter setting commands allow you to display or change the current value for a particular configuration parameter (Tables 5-3 through 5-11).

Current configuration parameter settings can be displayed in either setup mode or normal mode using the following syntax:

command<ENTER>

Most parameter values can be changed in setup mode only. Use the following command syntax when changing parameter values:

command=value<ENTER>

where value is a number or a parameter value. Use no spaces before or after the equal (=) sign. If you type an incorrect command or value, the display reads

??.

Changes to the parameters are saved as they are entered but typically do not take effect until you exit setup mode.

For example, to set the motion band parameter to 5, type the following:

MOTBAND=5D<ENTER>

5.1.5 Soft Reset

The RS command will reset the Tracer AV without losing configuration and calibration. It does reset consecutive number.

5.2 Saving and Transferring Data

Connecting a personal computer to the Tra ce r AV EDP port allows you to save configuration data to the PC or to download configuration data from the PC to a

Tra ce r AV. The following sections describe the

procedures for these save and transfer operations.

5.2.1 Saving Tra ce r AV Data to a Personal Computer

Configuration data can be saved to a personal computer connected to the EDP port. The PC must be running a communications program such as

PROCOMMPLUS information about serial communications wiring and EDP port pin assignments.

When configuring the values set for the BAUD and BITS parameters on the SERIAL menu match the baud rate, bits, and parity settings configured for the serial port on the PC. Set the PRNDEST parameter to EDP.

To save all configuration data, place the setup mode and send the DUMPALL EDP command.

Tra ce r AV responds by sending all configuration

communications software to send the saved configuration data to the complete, calibrate the

Tra ce r AV. When transfer is

Tra ce r AV as described in

Section 4.0.

NOTES:

• Calibration settings are included in the configuration data downloaded to the Tra ce r

. If the receiving Trace r AV is a direct

replacement for another

Tra ce r AV and the

attached scale is not changed, recalibration is not required.

• When downloading configurations that include changed serial communications settings, edit the data file to place the serial communications changes at the end of the file. Communication between the PC and

Tra ce r AV will be lost once the Trace r AV

receives settings for baud rate (BAUD parameter) or data bits and parity (BITS parameter) that do not match those configured for the PC.

6.1.2 Using the XE EDP Command

The XE EDP command can be used to remotely query

Tra ce r AV for the error conditions shown on the

the front panel. The XE command returns two 5-digit numbers in the format:

xxxxx yyyyy

where xxxxx contains a decimal represen tation of any existing error conditions as described in Table 6-2.

If more than one error condition exists, the number returned is the sum of the values representing the error conditions. For example, if the XE command returns the number 1040, this value represents the sum of an A/D reference error (1024) and an A/D calibration checksum error (16).

The second number returned (

yyyyy) uses the same bit

assignments as shown in T able 6-2 to indicate whether the test for the error condition was run. For example, the value

yyyyy = 50815 represents the decimal

eq u i v a le n t o f t h e b in a r y v a l u e 110 0 0 11 0 0 111 1111. Using the bit assignments in Table 6-2 , this value indicates all tests were run.

6.2 Status Messages

Two EDP commands, P and ZZ, can be used to provide status about the are described in the following sections.

6.2.1 Using the P EDP Command

The P EDP command returns the current displayed weight value to the EDP port, along with the units identifier. If the indicator is in an underrange or overload condition, the weight value is replaced with

&&&&&& (overload) or :::::: (underrange).

6.2.2 Using the ZZ EDP Command

The ZZ EDP command can be used to remotely query which annunciators are currently displayed. The ZZ command returns the currently displayed weight and a decimal number representing the LED annunciators currently lit. The format of the returned data is:

wwwwww uu zzz

where wwwwww uu is the current displayed weight and units,

zzz is the annunciator status value (see

Table 6-3). If more than one annunciator is lit, the second number returned is the sum of the values representing the active annunciators.

Example: If the annunciator status value returned on

the ZZ command is 145, the gross, standstill, and lb annunciators are lit. 145 represents the sum of the values for the standstill annunciator (128), gross mode annunciator (16), and the lb/primary units annunciator (1).

6.5 Conversion Factors for Secondary Units

The Tracer AV has the capability to mathematically convert a weight into many different types of units and instantly display those results with a press of the

Units key .

Secondary units can be specified on the FORMAT menu using the SECNDR parameter, or by using EDP commands.

NOTES:

• Multipliers are preconfigured within the

• Ensure that the secondary decimal point position is set appropriately for the scale capacity in the secondary units. If the converted value requires more digits than are available, the indicator will display an overflow message (

• For example, if the primary units are short tons, secondary units are pounds, and the secondary decimal point is set to 8888.88, the indicator will overflow if 5 tons or more are applied to the scale. With 5 tons applied, and a conversion factor of 2000, the secondary unit’s display needs five digits to the left of the decimal point to display the 10000 lb secondary units value.

A/D Readings

The Tracer AV uses averaged digital filtering to reduce the effect of vibration on weight readings. Adjustable threshold and sensitivity functions allow quick settling by suspending filter averaging, allowing the weight reading to jump to the new value. Figure 6-3 shows the digital filter parameters on the CONFIG menu.

Figure 6-3. Digital Filtering Parameters on the Configuration (CONFIG) Menu

Figure 6-4. Flow Diagram for Trace r AV Digital Filters

6.6.1 DIGFLx Parameters

The first three digital filtering parameters, DIGFL 1, DIGFL2, and DIGFL3, are configurable filter stages that control the effect of a single A/D reading on the displayed weight. The value assigned to each parameter sets the number of readings received from the preceding filter stage before averaging (see

6.6.2 DFSENS and DFTHRH Parameters

The three digital filters can be used by themselves to eliminate vibration effects, but heavy filtering also increases settling time. The DFSENS (digital filter sensitivity) and DFTHRH (digital filter threshold) parameters can be used to temporarily override filter averaging and improve settling time:

Figure 6-4). The overall filtering effect can be expressed by adding

the values assigned to the three filter stages:

DIGFL1 + DIGFL2 + DIGFL3

For example, if the filters are configured as DIGFL1=4, DIGFL2=8, DIGFL3=8, the overall filtering effect is 20 (4 + 8 + 8). With this configuration, each A/D reading has a 1-in-20 effect on the displayed weight value. Setting the filters to 1 effectively disables digital filtering.

• DFSENS specifies the number of consecutive scale readings that must fall outside the filter threshold (DFTHRH) before digital filtering is suspended.

• DFTHRH sets a threshold value, in display divisions. When a specified number of consecutive scale readings (DFSENS) fall outside of this threshold, digital filt ering is suspended. Set DFTHRH to NONE to turn off the filter override.

6.6.3 Setting the Digital Filter Parameters

Fine-tuning the digital filter parameters greatly improves Tracer AV performance in heavy-vibration environments. Use the following pr ocedure to dete rmine vibration effects on the scale and optimize the digital filtering configuration.

1. In setup mode, set all three digital filters (DIGFL1, DIGFL2, DIGFL3) to 1. Set DFTHRH to NONE. Return the

Tra ce r AV to normal mode.

2. Remove all weight from the scale, then watch the indicator display to determine the magnitude of vibration effects on the scale. Record the weight below which all but a few readings fall. This value is used to calculate the DFTHRH parameter value in Step 4.

For example, if a heavy-capacity scale produces vibration-related readings of up to 50 lb, with occasional spikes to 75 lb, record 50 lb as the threshold weight value.

3. Place the

Tra ce r AV in setup mode and set the digital filters (DIGFLx) to eliminate the vibration effects

on the scale. (Leave DFTHRH set to NONE.) Reconfigure as necessary to find the lowest effective values for the DIGFLx parameters.

4. With optimum values assigned to the DIGFLx parameters, calculate the DFTHRH parameter value by converting the weight value recorded in Step 2 to display divisions:

threshold_weight_value / DSPDIV

In the example in Step 2, with a threshold weight value of 50 lb and a display division value of 5lb: 50 /

5lb = 10DD.

DFTHRH should be set to 10DD for this example.

5. Finally, set the DFSENS parameter high enough to ignore transient peaks. Longer transients (typically caused by lower vibration frequencies) will cause more consecutive out-of-band readings, so DFSENS should be set higher to counter low frequency transients.

Reconfigure as necessary to find the lowest effective value for the DFSENS parameter.
