1.1Unpacking 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.
1.2Repacking
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.
1.3DC-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.

3.0Scale 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.
3.1Scale 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 1PORT 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.)
3.1.1Configuring 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.
Table 3-1. Specifications 16 and 17 Default Settings
Scale 2
00: Internal Scale 1
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.
3.1.2Scale 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.
• 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).

6.0Scale 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.
6.1Entering 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

7.4Global Setpoint Programming– Setpoints Not Tied to an Item Code
The DC-190 provides the flexibility to use the setpoint programming for parts counting applications that are
based on weight or quantity. SPEC 7 and SPEC 18 are used for configuring the setpoint type, latching, buzzer,
TTL outputs, and the number of setpoints.
The eight-pin DIN connector designation for the setpoint configuration is shown in Table 7-3. See Section 10.3
on page 52 for connector pinout information.
The available setpoint types are quantity, weight, percent quantity, and percent weight. The following procedure
is the same for each type; however, the type of setpoint selected determines the values being entered. Table 7-1
details the values for each setpoint and the values they represent.
