1.1 Unpacking and Inspection

Immediately after unpacking, visually inspect the DC-190 Ultra Count to ensure all components are included and undamaged. If any items were damaged in shipment, notify Rice Lake Weighing Systems and the shipper immediately.

Ensure all accessories are removed from the cartons, then replace all packing materials in the cartons and store in a safe place. Use the original cartons whenever shipment of the scale is required.

1.2 Repacking

If the DC-190 counting scale must be returned for modiﬁcation, calibration, or repair, it must be properly packed with sufﬁcient cushioning materials and the load cell must be locked to prevent damage to the load cell (see Section 2.1 on page 6).

Whenever possible, use the original carton when shipping the DC-190. Damage caused by improper packaging is not be covered by warranty.

1.3 DC-190 Scale Capacities and Resolutions

Counting scales specify two types of resolution:

•Weight (or external) resolution

• Counting (or internal) resolution

Weight resolution is displayed in increments of the full scale capacity which is divided into weight increments. For example, a 5-lb scale divided into 10,000 display divisions would display weight with 0.0005 lb divisions (10,000 divisions x 0.0005 lb = 5.0 lb).

Counting resolution is based on the internal resolution of the scale. The weight and counting resolutions for the DC-190 single- and dual-platform capacities are listed below.

Tables 1-1 through 1-3 list the scale capacities and resolutions for all models of the DC-190 counting scales.

3.0 Scale Setup

This section provides information about attaching scales and serial devices to the DC-190. Information presented describes both physical connections and values that must be speciﬁed when conﬁguring the DC-190 (see Section 4.0). If you know what scales and serial devices will be connected to the DC-190, you can use the SPEC Code Worksheets Section 10.1 on page 50 to record these values for later conﬁguration.

3.1 Scale Conﬁgurations

The DC-190 can be connected to up to three analog scale bases using the load cell ports (PORT 1 and PORT 2 shown in Figure 3-1). An Ohaus

232/PRINTER serial port for a total of four scale channels.

PORT 1 PORT 2

Explorer force balance can also connected to either the FORCE BALANCE or

Figure 3-1. DC-190 Scale Ports and Connectors

Attach SX-L single and SX-D dual scale platforms to PORT 1 (left connector); attach external scale base to PORT 2 (right connector). For three-scale conﬁgurations using either an SX-L and two external bases or three external bases, an optional Y-cable must be used to connect two of the bases to POR T 1. (A wiring diagram of the Y-cable is shown in Section 10.5 on page 55.)

3.1.1 Conﬁguring SPECs 16 and 17

SPECs 16 and 17 are used to assign the annunciators for each of the four scale channels (Scale No. annunciator on the DC-190 console).

All scale channels must be assigned, regardless of the actual number of scales attached.

Table 3-1 shows the values and default bit conﬁgurations for SPECs 16 and 17.

SPEC Default Setting Bits 3 and 2 Bits 1 and 0

16 0001 Scale 1

00: Internal Scale 1 01: Internal Scale 2 10: External Scale 11: Force Balance

17 1011 Scale 3

00: Internal Scale 1 01: Internal Scale 2 10: External Scale 11: Force Balance

Table 3-1. Speciﬁcations 16 and 17 Default Settings

01: Internal Scale 2 10: External Scale 11: Force Balance

Scale 4 00: Internal Scale 1

01: Internal Scale 2 10: External Scale 11: Force Balance

When conﬁguring SPECs 16 and 17, use the following rules:

• If a force balance is attached, it must be conﬁgured as Scale 1. That is, SPEC 16, bits 3 and 2, (Scale 1)

must be set to Force Balance (11).

• Scales attached to Port 1 are conﬁgured as

Internal Scale 1 and Internal Scale 2, regardless of whether the

actual scale base is internal (SX-L, SX-D) or external.

• The scale attached to Port 2 is conﬁgured as External Scale.

• All Scales (1–4) must be conﬁgured, and the value of each bit pair must be unique: each Scale (1–4) must have a different value. For example, do not attempt to conﬁgure two or more scales as

Scale; doing so will cause the DC-190 to lock up with an all 888888s display. See Section 10.7 on

External

page 57 for information about clearing this error condition.

SPECs 16 and 17 do not turn on the additional scales; by default, only one scale is enabled. Scales 2 and 3 are turned on and off using SPEC 25, bit 1 (Scale Type, single or dual) and SPEC 32, bit 0 (Scale Connected to Port

2). The force balance is turned on and off in SPEC 8, bit 3 (Force Balance on RS-232C port); the port used by the force balance is selected in SPEC 13, bits 2, 1, and 0 (RS-232 Connectors).

When adding a second or third platform to the DC-190, plug in the remote scale (or

Caution

dummy plug) before connecting AC power to the DC-190 and before enabling the added scales in the conﬁguration SPECs. Do not unplug a remote scale while the DC-190 is powered on.

3.1.2 Scale Conﬁgurations, No Force Balance Attached

Table 3-2 lists several scale conﬁgurations for single, dual, and console-only models of the DC-190 with no force balance attached. Required values for each conﬁguration are shown for SPECs 16 and 17 (including Scale No. assignments), SPEC 25 (bit 1), and SPEC 32 (bit 0). Because no force balance is attached, SPEC 8, bit 3, must be set to 0 for all listed conﬁgurations.

NOTES:

• SPEC 8, bit 3, must be set to 0 (0xxx) if no force balance is connected to the DC-190. Setting this bit to 1 with no force

balance connected will cause the scale to lock up.

• Console-only conﬁgurations require external AC adapter.

• If an external scale is attached to PORT 2 and only one scale is attached to the PORT 1 connector, the external scale is conﬁgured using Scale 3 parameters (SPECs 33, 36, and 37).

6.0 Scale Operations

The following sections contain detailed operator instructions for the DC-190 counting scale. Included are instructions to enter tare weights, toggle between net and gross weight, enter unit weights, perform inventory accumulation and reduction, and toggle between scales. All operator functions are conducted with the scale in the weighing or normal mode. See Section 7.0 on page 30 for information about scale programming.

Counting scale accuracy is primarily determined by the following factors:

• Sample size (number of pieces)

•Total sample size as a percentage of full scale capacity

• Piece-to-piece weight variation

As a general rule when determining sample size of fairly uniform pieces, the larger the sample size the greater the total sample weight, therefore, the better the counting accuracy. Selecting the smallest capacity scale that can obtain the highest counting resolution should be considered, but should not sacriﬁce the capacity required for the heaviest container of parts. For this speciﬁc application, a dual-platform scale may be the best selection.

There is a direct relationship between piece-to-piece weight variation (non-uniformity) and counting accuracy Therefore, elimination of the piece-to-piece weight variations can be accomplished by:

1. Isolating the sample used to calculate the unit weight and use the same sample to re-check the scale.

2. Recalculating the unit weight from lot-to-lot of parts. Parts manufactured on one machine may vary slightly from another machine relative to weight.

3. Tightening the manufacturing tolerances on the parts reduces piece weight v ariations and increases count accuracy.

6.1 Entering Tare Weights

Tare weights can be entered in the scale by one of two methods: one-touch tare or digital tare.

NOTES:

• SPEC 27, bit 2 (Digital Tare Setting) must be a 1 to allow digital tare.

• SPEC 27, bits 0 and 1 (Tare Range) must be set to the appropriate tare range value. Default is 00, 100 percent of full scale.

One-Touch Tare, Tare Weight Unknown

1. If the tare weight value is not known, place the container, box, or item to be tared on the scale and press

TARE. The WEIGHT display should now show 0 and the NET annunciator should illuminate.

2. Remove the container, box, or item from the scale. The

WEIGHT display should show a negative weight

value (weight of the tared container, box, or item).

3. Press

Digital Tare, Tare Weight Known

TARE to reset tare to zero.

1. If the tare weight value is known, use the numeric keypad to key in the value and then press TARE.

2. Press

NOTE: For digital tare entry, the decimal must be in the appropriate place as it would be displayed in the WEIGHT

display. For example, .250 would be entered as 0.250, not .250. The WEIGHT display shows weight entered with a negative sign indicating that it is a tare weight.

TARE to reset tare to zero.

6.2 Toggle Between Scales

To switch the displays from Scale 1 through Scale 4, press the SCALE key when in weighing mode. Only scales present are selected. For example, a two-scale system switches between Scale 1 and Scale 2 only. In a four-scale conﬁguration, the

SCALE key functions as follows:

SCALE key to change from Scale 1 to Scale 2. SCALE key to change from Scale 2 to Scale 3. SCALE key to change from Scale 3 to Scale 4. SCALE key to change from Scale 4 to Scale 1.

6.3 Toggling Between Net and Gross Weight

To toggle between net and gross weight, a tare value must be entered into the scale (see Section 6.1). NOTE: SPEC 25, bit 0 (Gross Mode Available) must be set to 0 (default) to enable gross mode.

After a tare value is entered into the scale, items placed on the scale will cause the and allow toggling between net weight and gross weight.

An example of toggling between net weight and gross weight is shown below:

1. Place 0.5 lb weight on the scale and then press

2. Place another 0.5 lb weight on the scale. The scale

TARE once. The WEIGHT display should show 0.000 lb.

WEIGHT display should now show 0.500 and the NET

annunciator should be illuminated.

3. Press

NET/GROSS. The WEIGHT display should show 1.000 and the GROSS weight annunciator is

illuminated. The UNIT-WEIGHT and the QUANTITY displays go blank.

4. Press

NET/GROSS. The WEIGHT display now shows 0.500 and the NET weight annunciator is

illuminated.

6.4 Entering Unit Weights

Entering unit weights can be done either by sampling, as described in Section 6.4.1, or by key entry as described in Section 6.4.2.

SPEC 0, bit 0 ( speciﬁes that the Setting bit 0 to 1 speciﬁes that the unit weight value shown is per one piece (A.P.W.).

NOTE: SPEC 4, bits 1 and 2 (Insufﬁcient Sample Level) control unit weight sampling. The default value is 0.1 percent.

6.4.1 Unit Weight Operation by Sampling

Unit weight operation by sampling is accomplished by placing a known quantity of pieces to be sampled on the scale and then pressing the compared to the weight of the sample.

1. Press

2. Place 10 pieces of the item to be sampled on the scale.

PIECES key again to recompute the unit weight.

6.4.2 Unit Weight Operation by Key Entry

Unit weight operation by key entry is accomplished by using the numeric keypad to enter the known value of the unit weight and then pressing the

UNIT WEIGHT key. An example of unit weight operation by key entry is shown

below:

1. With the display in the weighing mode, use the keyboard to enter the known unit weight, for example,

200.00. NOTE: The setting for SPEC 0, bit 0, determines whether the value entered is per piece (A.P.W., if set to 1)

or per 1000 pieces (if set to 0).

2. Press UNIT WEIGHT key to enter the unit weight.

3. Place a 2 lb. weight on the scale. The scale displays the quantity for the weight placed on the scale. For example, the

WEIGHT display reads 2.000, the UNIT-WEIGHT display reads 200.00 (per 1000 pieces),

and the QUANTITY display reads 10).

6.4.3 Clearing Unit Weight

To clear a unit weight:

1. Remove weight from scale.

2. Press the

CLEAR key.

6.5 Part Accumulation and Reduction–Without Recalling an Item Code

The DC-190 counting scale is capable of part number inventory tracking and maintenance using the stored item code function of the scale software (see Section 7.0 on page 30). Additionally, the scale has the capability to acquire the total number of parts using the accumulation or reduction function of the scale (similar to the add/ subtract functions of a calculator).

6.5.1 Part Accumulation

To ﬁnd the total accumulated quantity of similar containers ﬁlled with parts, use the accumulation procedure detailed below. Six containers are used in this example procedure; it is assumed that all containers are of the same weight.

1. Conduct a sampling process (see Section 6.4) to determine the unit weight of the pieces.

2. Enter known tare weight, or place empty container on scale to perform tare function (see Section 6.1).

3. Place Container 1 (full of parts) on the scale.

4. Press the

+ key to store the total in Container 1. The MEMORY annunciator lights. The WEIGHT display

brieﬂy shows totAL and the QUANTITY display shows the total pieces in the ﬁrst container.

5. Remove Container 1 and place Container 2 (full of parts) on the scale.

6. Press the

+ key (total is equal to Container 1 plus Container 2).

7. Continue with the remainder of the containers in the same accumulation method. The total number of parts stored in all six containers will then be stored in the accumulation register.

8. To view the total, make sure that the scale platter is empty and press the

7.0 Scale Programming

7.1 Item Code Storage

Code numbers allow you to store information for the parts that are counted most frequently. This eliminates the need for re-entering data for each of these parts during part count. Up to 200 item code numbers can be programmed in the DC-190 counting scale; with IMS software, the number of item codes is unlimited.

The procedures for storing the unit weight, tare weight, quantity, part number, part name, setpoints, and lot number with an item code are described below. You can enter all of this information for each item code or only the data pertinent to your application. For example, if you only want to store only the unit and tare weights, you can bypass Steps 5 through 13 and go to Step 14.

Program Unit Weight, Tare Weight, Quantity, Part Number, Part Name, Setpoints, and Lot Number

1. Press MODE key to enter program mode. The MODE annunciator will light, the WEIGHT display will

read ProG, and the QUANTITY display will read C XX (XX represents the number of item codes stored in the DC-190 memory).
