Note

The CW-90/CW-90X is a high-speed digital weight indicator and scale base programmed to compare weight readings with predetermined tolerance limits defining an “accept” band.

If the current weight reading is within the acceptable range, the green “ACCEPT” LED is illuminated. If the current weight reading is less than the acceptable range, one or more of the red “UNDER” segments is illuminat

ed. If the current weight reading is greater than the acceptable range, one or more of the yellow “OVER” segments is illuminated.  Features include:

• L arge .8” (20.3 mm) LED display with “under,” “accept,” and “over” bands

• Full numeric keypad (CW-90 only)

• Four configurable digital inputs/outputs

• Two independent communication ports (2) full duplex, (1) unidirectional active 20

1.3 Operating Modes

The CW-90/CW-90X has two modes of operation:

Normal (Weighing) Mode

Normal mode is the “production” mode o on whether a tare has been entered. LED annunciators indicate the type of weight value.

Menu mode

Most of the procedures described in this manual, including configuration and calibration, require in Menu mode.To enter Menu mode, press the indicator displays “AUDIT.”  If the Audit jumper is in the “OFF” position, remove the Insert a screwdriver into the access hole and press the setup switch once to enter Menu mode.

2.2 Leveling

Note

WARNING

Note

Select a location for the CW-90/CW-90X that is reasonably level and free of vibrations and air currents. Adjust the four corner feet on the base and refer to the bubble level on the inside frame. The base should not rock and the feet should have solid contact with the surface. If using a column, adjust the two column feet until they make solid contact with the support surface.

Ensure the nut on each foot’s bolt is secured flush against the scale base.

2.3 Making Power Connections

The power source used for the CW-90 must be properly grounded to an acceptable earth ground. If the indicator is remotely mounted, the platform must be separately grounded from the chassis ground screw located on the bottom of the platform. Connect this screw with 18 gauge wire to the same earth ground system as the AC power source. Failure to ground the base may cause static buildup and incorrect weights.

The CW-90 must be installed near an easily accessible power outlet to allow for quick disconnect in case of emergency.

2.4 Enclosure Disassembly

The indicator enclosure must be opened to connect cables for load cells, communications, and digital inputs/outputs.

Before opening the unit, ensure the power cord is disconnected from the power outlet. The power outlet must be located near the indicator to allow the operator to

Ensure power to the indicator is disconnected, then place the indicator face-down on an antistatic mat. Remove the screws holding the backplate to the enclosure body, then lift the backplate away from the enclosure and set it aside.

easily disconnect power to the unit.

2.5 Load Cell Wiring

On all complete units (indicator head and base), the load cell has been wired to the indicator’s CPU load cell terminal at the factory. If you have purchased just the indicator head, you must wire the load cell.  Wire the cable to the CPU board’s J1 connector as shown in Table 2-1. Leave any excess cable outside of the indicator head during installation

If using a 4-wire connection, set JP1 and JP2 to ON. If using a 6-wire connection, set JP1 and JP2 to OFF.

Except for the power cord, all cables routed through the cord grips should be grounded against the indicator enclosure. Do the following to ground shielded cables.

• Use the lockwashers, clamps, and kep nuts provided in the parts kit to install grounding clamps on the enclosure studs adjacent to cord grips. Install grounding clamps only for cord grips that will be used; do not tighten nuts.

• Route cables through cord grips and grounding clamps reach cable connectors. Mark cables to remove insulation and shield as described below:

• For cables with foil shielding, strip insulation and foil from the cable half grounding clamp (see Figure 2-3). Fold the foil shield back on the cable where the cable passes throug side of foil is turned outward for contact with the grounding clamp.

2.10 Battery Replacement

CAUTION

Note

CAUTION

Risk of explosion if battery is replaced with incorrect type. Dispose of batteries per manufacturer instructions.

The lithium battery on the CPU board maintains the real-time clock and protects data stored in the system RAM when the indicator is not connected to AC power. Data protected by this battery includes time and date, IDs, and configuration information. If any data is lost, the indicator configuration can be restored from the PC. Watch for the low battery warning on the LCD display and periodically check the battery voltage on the CPU board. Batteries should be replaced when the indicator low battery warning comes on, or when battery voltage falls to 2.2 VDC. Life expectancy of the battery is 10 years. Use Revolution to store a copy of the configuration before attempting to replace the battery.

The CW-90/CW-90X can be calibrated using the front panel, EDP commands, or Revolution®.

Calibration can be performed in two places within the menu: the CALIBR menu shown in Figure 4-1 and the SCALE submenu shown in Figure 3-5 on page 18. The CALIBR menu is a “quick access” calibration; for more

in-depth scale setup and calibration, use the menus found under SETUP»CONFIG»SCALE.

Calibration consists of the following steps:

• Zero calibration

• E ntering the test weight value

• Span calibration

The CW-90/CW-90X requires the WZERO and WSPAN points to be calibrated. The linearity points are optional,

but must NOT duplicate zero or span. It also acts as an EXECUTE key, and accepts the value if calibration was successful.

During calibration, the ENTER key acts as a data entry confirmation key.

• Optional five-point linearization

• Optional rezero calibration for test weights u

sing hooks or chains.

4.4 More About Calibration

The following topics provide additional information about compensating for environmental factors (Section 4.4.1) and diagnostic information for determining expected and span coefficients.

4.4.1 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 ENTER to show the test weight value. Press

ENTER to save the value, then press to return to the

5.4.3 WeighVault

WeighVault is a PC program which allows CW-90/CW-90X users to add, edit, and access IDs over a network connection. WeighVault surpasses the CW-90/CW-90X's 50 ID limitation and eliminates front-panel entry of ID parameters. It also collects data as transactions occur, and provides detailed transaction and productivity reports which can be exported to Excel, Word, or PDF. For WeighVault to function, the following criteria must be met:

• Ethernet card (wired or wireless) installed in the CW Interface Installation and Configuration Manual or PN108680 WLAN Installation Instructions).

• P C running the WeighVault service must have a static IP address

• IP address assigned to the CW

• WeighVault enabled in the CW

-90/CW-90X menu (VAULT parameter; see Section 3.4.2 on page 23)

• P ort corresponding to the Ethernet card must be selec page 23)

Once the above criteria have been met, IDs

can then be entered into WeighVault and saved on the PC’s hard drive.

The Edit Product dialog box in Figure 5-6 shows ID parameters which can be saved in WeighVault.

5.5 Negative Checkweighing

You can use negative checkweighing if you have an item which you want to take weight away from. For exam ple, if a product on the CW-90/90X weighs 20 pounds and you want to remove weight in 2 pound increments, with negative checkweighing enabled, the Over value could be set to -3 and the Under value could be set to -1. The Accept band would therefore be -2, illuminating the green LED when the desired weight is removed from the product.

Negative checkweighing is only operable in Range mode. The Target key is not used. When entering Over/Under values and printing, the negative symbol is not displayed. These numbers are still treated as negative values despite the symbol not being displayed. COM port settings are limited to L-Stab, Demand (only if NEGCKW is set to ON rather than AUTO), and Wait SS (see Figure 3-10 on page 29).

6.0 Serial Commands

The CW-90/CW-90X can be controlled by a PC or remote keyboard connected to an indicator serial port. Control is provided by a set of serial commands that can simulate front panel key press functions, display and change setup parameters, and perform reporting functions. This provides the ability to print configuration data or to save to your hard drive.

6.1 The Serial Command Set

The serial 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 a serial command is processed, the CW-90/CW-90X responds with the message command was received and has been executed. If the command is unrecognized or cannot be executed, the CW-90/CW-90X responds with

Gross, net, and tare weights are 8 digits in length, including sign and decimal point, followed by a space and a one- to five-digit units identifier. Total field length with units identifier is 10-14 characters. Depending on what units are configured, the units identifier will be lb/oz, lb, oz, g, or kg.

Gross, net, tare, and accumulator weights can be printed in any configured weight units by adding the following modifiers to the gross, net, tare, and accumulator weight commands: /P (primary units), /D (displayed units), /S (secondary units), /T (tertiary units). If not specified, the current displayed units (/D) is assumed. Example: To format a ticket to show net weight in secondary unitsm, use the following command: <N/S>.

ID and consecutive number (CN) fields are 1–6 characters in length, as required.

* If nn is not specified, 1 is assumed. Value must be in the range 1–99.

7.2 Customizing Print Formats

The following sections describe procedures for customizing the the EDP port, the front panel ( Revolution configuration utility.

GFMT, NFMT and CFMT formats using

PFORMT menu), and the

7.2.1 Using the EDP Port

With a personal computer, terminal, or remote keyboard attached to the CW-90/CW-90X EDP port, you can use the EDP command set to customize the print format strings.

To view the current setting of a format string, type the

of the string (

name

GFMT or NFMT) and press Enter. For

example, to check the current configuration of the

GFMT format, type GFMT and press Enter. The indicator

responds by sending the current configuration for the gross format:

GFMT=<G> GROSS<NL>

To change the format, use the GFMT or NFMT EDP command followed by an equals sign (=) and the modified print format string. For example, to add the name and address of a company to the gross format, you could send the following EDP command:

Indicator must be placed in the config mode with CONFIG shown on

GFMT=FINE TRANSFER CO<NL>32400 WEST HIG

HWAY ROAD<NL>SMALLTOWN<NL2><G>

GROSS<NL>

the display.

A ticket printed using this format might look like the following:

FINE TRANSFER CO 32400 WEST HIGHWAY ROAD SMALLTOWN

1345 lb GROSS

7.2.2 Using the Front Panel

If you have no access to equipment for communication through the EDP port or are working at a site where such equipment cannot be used, you can use the

PFORMT menu (see Figure 7-1) to customize the print

formats. Using the

PFORMT menu, you can edit the print format

strings by changing the decimal values of the ASCII characters in the format string.

Lower-case letters and some special characters cannot be displayed on the CW-90/ CW

-90X front panel and are shown as blanks. The CW-90/CW-90X can send or receive any ASCII character; the character printed depends on the particular ASCII character set implemented for the receiving device.

9.3 Status Messages

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

9.3.1 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).

9.3.2 Using the ZZ EDP Command

The ZZ EDP command can be used to remotely que ry which annunciators are currently displayed on the indicator front panel. 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:

9.5 Digital Filtering

The CW-90/CW-90X 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 9-2 shows the digital filter parameters on

the CONFIG menu.

Figure 9-2. Digital Filtering Parameters on the Configuration (CONFIG) Menu

62 CW-90/90X Checkweigher

Figure 9-3. Flow Diagram for CW-90/CW-90X Digital Filters

Page 67

9.5.1 DIGFLx Parameters

The first three digital filtering parameters, DFLTR1, DFLTRL2, and DFLTR3, 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 Figure 9-3).

The overall filtering effect can be expressed by adding the values assigned to the three filter stages:

DFLTR1 + DFLTR2 + DFLTR3

For example, if the filters are configured as DFLTR1=4, DFLTR2=8, DFLTR3=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.

9.5.2 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 temporaril y override filter averaging and improve settling time:

• 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 filtering is suspended. Set DFTHRH to NONE to turn off the filter override.

9.5.3 Setting the Digital Filter Parameters

Fine-tuning the digital filter parameters greatly improves indicator performance in heavy-vibration environments. Use the following procedure to determine vibration effects on the scale and optimize the digital filtering configuration.

1. In menu mode, set all three digital filters (DFLTR1, DFLTRL2, DFLTR3) to 1. Set DFTHRH to NONE. Return indicator 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 indicator in menu mode and set the digital filters (DFLTRx) to eliminate the vibration effects on the scale. (Leave DFTHRH set to NONE.) Reconfigure as necessary to find the lowest effective values for the DFLTRx parameters.

4. With optimum values assigned to the DFLTRx 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.

9.5.4 Audit Trail Support

Audit trail support provides tracking information for configuration and calibration events. To prevent potential misuse, all configuration and calibration changes are counted as change events.

Use the Audit menu or Revolution to display audit trail information. This includes the legally relevant (LR) version number (software version for the code that provides audit trail information), a calibration count and, if REGULA=NTEP, a configuration count. The exact format of the information shown depends on the regulatory agency specified for the REGULA parameter (FEATUR menu).

Audit trail information can be printed from Revolution or by sending the DUMPAUDIT serial command.
