1.4 DC-190 Console Figure 1-1 shows the DC-190 console with annunciators and numeric keypad. Annunciators are described in Section 1.4.1; Section 1.4.2 describes the DC-190 keypad. Figure 1-1. DC-190 Keypad and Displays 1.4.1 Annunciators Table 1-4 shows a list of the annunciators that the DC-190 uses to provide additional information about the value being displayed. The annunciators are illuminated when the specific function is being performed.
1.4.2 DC-190 Keypad Table 1-5 lists the keys and key functions of the DC-190 Ultra Count keypad (see Figure 1-1 on page 4). Description Key through 0 9 Used to enter numeric values. When using the scale, first enter a numeric value, then press the appropriate function key. Used to enter numeric values containing a decimal point. NOTE: A numeric value must be entered before the decimal point. For example, .250 would be entered as 0.250.
2.0 Installation This section describes the procedure for the installation and setup of the DC-190 counting scale. 2.1 NOTE: Beginning in 2003, setscrews with slotted heads will replace the hex head types, and will no longer require the 2mm hex wrench for removal. Locking and Unlocking Caution Do not turn scale upside down. Always work with scale on its side! Damage to the load cell can occur if the scale is turned upside down.
2.3 Powering Up the DC-190 The DC-190 can be operated either from an AC power source or with an optional rechargeable battery pack (DC power). The DC power allows the unit to be completely portable. Instructions for DC operation are contained in Section 2.3.3. 2.3.1 AC Power Source To power-up the DC-190 using the AC power cord: 1. Connect female end of AC power cord (Figure 2-4) under scale base. If the scale is connected to AC power while in the OFF condition, no warm-up is necessary.
5. Place scale on side. Remove four top cover screws (shown in Figure 2-7). Set scale on legs and remove top cover. If the DC-190 scale is operated with the battery pack removed, isolate the positive (+) and negative (–) leads so that they do not make contact with each other or any part of the scale frame or any sensitive electronic components. Caution 2.3.3 TOP COVER SCREWS DC Battery Operation To power-up the DC-190 using the optional battery: 1. Remove AC power cord from bottom of scale. 2.
2.5 Installing Cable Strain Relief To prevent load cell or peripheral cable damage from bending and twisting, cable strain reliefs are used in the back of the DC-190 keyboard. Each DC-190 counting scale comes equipped with these rubber strain reliefs and should be installed on initial scale setup. 1. Remove the three 4 mm x 8 mm panhead screws securing the bracket to the back of the keyboard. 2. Remove rubber strain relief covering the two 14-pin load cell cable ports.
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.
• • 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 External Scale; doing so will cause the DC-190 to lock up with an all 888888s display. See Section 10.7 on page 57 for information about clearing this error condition.

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.
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: 1. Press SCALE key to change from Scale 1 to Scale 2. 2. Press SCALE key to change from Scale 2 to Scale 3. 3. Press SCALE key to change from Scale 3 to Scale 4. 4.
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.
illuminated and the display shows the quantity of parts remaining. 6. Remove a number of parts from the container and press the – key again. The MEMORY annunciator is illuminated and the display shows the quantity of parts remaining. NOTE: If SPEC 32, bit 1 (Auto Exit from Part Accumulation and Reduction Mode) is set to 0, the scale will not auto exit from displaying the total amount. To return to the weighing mode, press the CLEAR key. 6.5.
7.0 7.1 Scale Programming 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.
SPEC 7, bits 0,1 Setpoint Type 00 Percent quantity Setpoint Designation Setpoint 1: Quantity The quantity value can be no greater than 999999. Setpoint 2: Percent of Setpoint 1 The percentage value can be no greater than 999%. The value for Setpoint 2 is calculated by multiplying the value for Setpoint 1 by the percentage value entered for Setpoint 2. NOTES: • If Setpoint 1 is equal to 999999, then Setpoint 2 must be set less than or equal to 100%.
NOTE: When you hear the beep, the display shows the last item code in memory. Press the – key to review the item codes in reverse order. 4. Press the MODE key to return to Step 1. 5. Press the MODE key again to return to weighing mode. Delete Item Memory The following procedure describes the steps used to delete all information stored within each item code (unit weight, tare weight, part number, quantity, part, setpoints, and lot number) or any specific information stored within each item code.
Re-Computing Item Code Unit Weight 1. 2. 3. 4. Recall item code from memory (see Section or Section ). Place items to be counted on the scale. Press the PIECES key for recomputing the unit weight. Press the UNIT WEIGHT key to store the new unit weight into memory. Set New Item Code with Tare and Unit Weight NOTE: This can only be conducted if SPEC 4, bit 3 is 0 (Yes). 1. Enter the item code using the numeric keypad or Teraoka Code (see Section , Step 2). 2.
7.4 Global 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.
10.3 Connector Pinouts The DC-190 provides CTS/RTS hardware handshaking lines on both the 8-pin DIN and 9-pin D-Sub connectors. For devices that do not require hardware handshaking, short the CTS/RTS lines on the scale side of the cable. 8-Pin DIN Female 9-Pin D-Sub Female Figure 10-1. 8-Pin DIN Female Figure 10-3.
