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.

Sets the current gross weight to zero, provided the amount of weight to be removed or added is within the specified zero range and the scale is not in motion. The zero band is defaulted to 1.9% of full scale, but can be configured for up to 100% of full scale.

1.9% is required for legal for trade applications.

Switches the weight display to an alter kg, g, lb, oz, or lb/oz. Conversions of the weight reading, the Tare value, the Over value, and the Under value occur when the unit of measure is changed with the Units key.

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.

• For cables with braided shielding, strip cable insu of insulation only to expose the braid where the cable passes through the clamp (see Figure • on page 8).

See Section 3.3 on page 17 for descriptions, and see Section 4.0 on page 36 for calibration procedures.

Calibration can be perfor Figure 3-5 is an in-depth scale setup and calibration. A “quick access” calibration is shown in Figure 4.1 on page 36.

Specifies the number of full scale graduations.

The value entered must be in the range 1–100000 and should be consistent with legal

equirements and environmental limits on system resolution.

To calculate GRADS, use the formula: GRADS = Capacity / Display Divisions.

Display divisions are specified under

med in two places within the menu: the CALIBR menu shown in

the FORMAT submenu.

If RANGE is displayed after the value is entered, the value is too large or small for the given parameter.

Select your primary, secondary, and tertiary units of me oz, and g. Secondary and tertiary units can also be set to lb/oz (lb/oz is not legal for trade), or off.

Automatically zeroes the scale when within the ZRANGE and scale is at standstill. Specify the zero tracking band in ± display divisions. Maximum legal value varies depending on local regulations.

For scales using linear calibration, do not set the zero tracking band to a value greater than that specified for the first linearization point.

Selects the range within which the scale can be zer

1.9% around the calibrated zero point, for a total range of 3.8%. Indicator must be at standstill to zero the scale. Use the default value for legal-for-trade applications.

Sets the level, in display divisions, at which 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 annu requiring standstill (zero, tare, print) are performed regardless of scale motion. If 0 is selected, ZTRKBND must also be set to 0.

Overload. Determines the point at whic message is displayed. Maximum legal value varies depending on local regulations.

Specifies the length of time the scale must be ou the scale is considered to be at standstill. Values greater than 10 are not recommended.

Sample rate. Selects measurement rate, in samples per second, of the analog-to-digital converter

. Lower sample rate values provide greater signal noise immunity.

Settings of 120Hz or above may be too fast to provide the desired stability in some static weighing applications.

Selects the digital filtering rate used to reduce the ef immediate area of the scale. The overall filtering effect can be expressed by adding the values assigned to the three filter stages:

DFLTR1 + DFLTR2 + DFLTR3 See Section 9.5 on page 62 for information on digital filtering.

Choices indicate the number of A/D 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.

Digital filter cutout sensitivity. Specifies the number of c outside the filter threshold (DFTHRH parameter) before digital filtering is suspended.

Digital filter cutout threshold. Specifies the filter thr 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.

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

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

In DELAY mode, the indicator performs a power up displa warm up period. If no motion is detected during the warm up period, the indicator becomes operational when the warm up period ends; if motion is detected, the delay timer is reset and the warm up period repeated.
