    Leveling Select a location for the CW-80 that is reasonably level and free of unneces- sary vibrations and air currents. Adjust the four corner feet on the base until the bubble level on the inside frame of the unit reads level. When level, the base should not rock and all four feet should have solid contact with the support surface.

  • Page 36: Operating Modes

    Operating Modes Before You Begin In this section: The CW-80 has four separate operating modes to accommodate different Before You Begin applications. The major difference between these four operating modes is the manner in which Under/Accept/Over tolerance values are established, Overview of Operating and the manner in which they can be changed once set.

  • Page 37: Overview Of Operating Modes

    Overview of Operating Modes The following pages use graphics to summarize how each operating mode functions. This page provides a key (using the two figures below) for reading those graphics on the following pages. Note that all graphics assume you are using a scale with 30 lb capacity, set up for 3,000 grads (20 x .01), a Count By of 1, and 2 decimal places.

  • Page 38: Target Mode

    TARGET Mode In TARGET mode, all tolerances (Un 1, Un 1-2, Un 2, Ov 1, Ov 1-2, Ov 2) are pre-set by the installer. The operator places a sample weight of the product on Checkweigher-Acquired Weight Value by Pressing TARGET Key the scale and presses the TARGET key.

  • Page 39: Ou Set Mode

    OU SET Mode In OVER UNDER SET mode, the lower (Un 1) and upper (Ov 1) limits of the ACCEPT band are entered digitally through the keyboard by the operator. The operator presses the UNDER key, Operator Numeric Entry Required then enters the Un 1 value.

  • Page 40: Displaying And Setting Over And Under Tolerance Values

    Displaying and Setting Over and Under Tolerance Values UNDER This section explains how to set or alter the values that define the OVER ACCEPT band. When in OU SET mode, the operator uses keypad buttons to digitally set or alter Over (Ov 1) and Under (Un 1) values around the ACCEPT band. When in TARGET or PTT/SET mode, these Ov 1 and Un 1 values defining the ACCEPT band are initially acquired from weights on the platter, but can then be altered by the operator using keypad buttons.

  • Page 43: Setting Tare Values

    Setting Tare Values The CW-80 allows two methods for establishing tares. The most common method involves placing the actual tare weight on the scale, then pressing TARE to allow the scale to acquire that value. If this is the method of choice, the TARE menu must be set to PTT (Push To Tare) in Configura- tion mode.

    Zeroing the Scale Upon power up, or upon exiting the Setup menu, the CW-80 will automati- cally zero off weight on the platter up to the amount established in the Zero Band setting. To prevent unwanted zero shifts, be certain platter is empty when powering up the indicator and when exiting the Setup mode.

    Advanced Features Bar Graph In this section: The Bar Graph is a programmable 5-segment, 7-range LED that gives you a Bar Graph quick visual method of determining if a container is too heavy (Over), too light (Under), or in a correct range (ACCEPT). The functions of the 5 LEDs Print Formats (or segments) are described in the following paragraphs.

  • Page 74: Green Segment (1)

    Green Segment (1) The green segment (Figure 7-1) indicates an Accept value. When illuminated, the green segment light indicates that the container weight is within the actual acceptable band of weight limits (Figure 7-2). Amber Segments (2) The amber segment (Figure 7-1) indicates an Over weight value. When illuminated, the amber segment(s) indicate that the container weight is more than the highest acceptable weight value.

  • Page 75: Print Formats

    Therefore, to set the CW-80 so that Un 1, Un1-2, and Un 2 light at .01 intervals, parameters should be set to 5. Because these values are cumulative, the first red segment (Un 1) will light at .01 lb under target, both red segments (Un 1-2) at .02 lb, and the leftmost red segment (Un 2) at .03 lb.
