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.

Table 7-3. Pin Out for Setpoint Configuration

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.

7.4.1Procedure

The following steps present the procedure for setpoint programming by percent quantity, percent weight, upper and lower quantity limit, and upper and lower weight limit.

1.Press the MODE key to go into the programming mode. The MODE annunciator illuminates, the WEIGHT display shows ProG, and the QUANTITY display shows C XX.

2.Press the + key to enter global setpoint values. The WEIGHT display shows Set 1, and the QUANTITY display shows the value for Setpoint 1.

3.Enter the setpoint value using numeric keys.

4.Press the + key to store the value and move to the next setpoint.

5.Press the MODE key to exit the programming mode and return to the weighing mode.

NOTES:

The DC-190 can program up to six setpoints by repeating Steps 2 through 4. SPEC 18, bits 0, 1, and 2 (Number of Setpoints) determine the number of setpoints used. The six setpoints are TTL output for quantity or weight, but not percentage quantity or percentage weight. These six values may be programmed 1 through 6 (low-to-high) or 1 to 6 (high-to-low).

If you recall an item code, those values stored with the item are used. Item setpoints take priority.
