1.0 INTRODUCTION • The CBDa series offers a range of an accurate, fast and versatile counting scales that can use one additional external platform (Remote scale) for weighing or counting of heavier items. • These counting scales have the ability to store detailed information on the products that are used most (PLU). • The scale can be operated using either pounds only, kilograms only or can be switched between pounds and kilograms. • All have stainless steel weighing plat

3.0 INSTALLATION 3.1 LOCATING THE SCALES • The scales should not be placed in a location that will reduce the accuracy. • Avoid extremes of temperature. Do not place in direct sunlight or near air conditioning vents. • Avoid unsuitable tables. The table or floor must be rigid and not vibrate. • Avoid unstable power sources. Do not use near large users of electricity such as welding equipment or large motors. • Do not place near vibrating machinery. • Avo

• Level the scale by adjusting the four feet. The scale should be adjusted such that the bubble in the spirit level is in the centre of the level and the scale is supported by all four feet. • Attach the power supply cable to the connector on the right side of the scale base. Plug in the power supply module. The power switch is located at the right side of the scale base. • The scale will show the model number in the “Weight” display window (CBDa 15- where 15 denotes the max

REMOTE SCALE CONNECTION The cable for the load cell goes to a 9 pin D-subminiature plug connector with the following connections: Pin numbers Connection Pins 1,2 - Excitation (0 V) Pins 4,5 + Excitation (+5 V) Pin 7 + Signal Pin 8 - Signal (The sense wires connections of a six wire load cell are not used but can be connected to the respective Excitation pins).

4.0 KEY DESCRIPTIONS [0-9, •] These keys are used to manually enter a value for tare weights, unit weight and sample size. A secondary function is to enter alpha-numeric characters for PLU descriptions etc. [CE] Pressing this key clears the unit weight or an erroneous entry. It also clears the memory accumulation when the total is displayed. [M+] This key is used to add the current count to the accumulator. It also recalls the memory when pressed with no load on the

[Local Rem] This key is used to select the local or remote scale. [Tare/Zero] This key has a combined Zero and Tare function. If the net weight is below ±2% of maximum then it acts as a Zero key. This sets the zero point for all subsequent weighing by setting the display to zero. It also tares the scale by storing the current weight in the memory as a tare value, subtracting the tare value from the total weight and displaying the results as a net weight. 5.0 DISPLAYS

5.2 UNIT WEIGHT WINDOW • This display will show the unit weight of a sample. This value is either entered by the user manually or computed by the scale. The unit of measure is either gram on all scales with kilogram selected as weighing unit or in pounds. • When the scale has determined that there is insufficient number of samples to accurately determine the count, an arrow will be shown above "Smpl". • When the unit weight is not large enough to determine an accurate count, t

6.0 OPERATION • The basic weighing functions are same for both the scales- local and remote. However the number of weighing divisions may be less on the remote scale dependant on the total capacity of the load cell/s used. • Each scale (local or remote) has the ability to count parts based on the current unit weight. This is best obtained by performing a sample on the local scale which may have the best sensitivity. Then the scale can be switched to the remote where large quant

6.1 ZEROING AND TARING THE DISPLAY The Tare and Zero function are combined into one key. When the gross weight is within ±2% of the zero, set at power on for either scale then a new zero is set. If the gross weight is greater than ±2% then the tare function is performed. ZEROING • You can press the [Tare/Zero] key at any time to set the zero point from which all other weighing and counting is measured. When the zero point is obtained the Weight display will show the indica

• When the container is removed a negative value will be shown. If the scale was tared just before removing the container this value is the gross weight of the container plus all products that were removed. The zero indicator will also be ON because the platform is back to the same condition as it was when the [Tare/Zero] key was last pressed. Second method of entering a tare value: • This method allows you to enter a value for the tare weight from the keypad. This is useful

6.2 MEMORY FUNCTIONS The [M+] key will add the results of a weighing into memory, regardless of whether the local or remote scale is being used for the weighing. 6.2.1 Manual accumulation • The values (weight and count) shown on the display can be added to the values in the accumulator by pressing the [M+] key. The "Weight" display will show the total weight, the "Count" display will show the total accumulated count and the "Unit Weight" display shows the number of times item

6.3 PARTS COUNTING The basic function of parts counting is same for both the scales. In order to do parts counting it is necessary to know the average weight of the items to be counted. This can be done either by weighing a known number of the items and letting the scale determine the average unit weight or by manually inputting a known unit weight using the keypad. Either of the scales can be used to determine the sample unit weight or for the manual entry which can be used to coun

6.3.2 Entering a known Unit Weight • If the unit weight is known it can be entered using the keypad. • Enter the value of the unit weight using the numeric keys followed by pressing [U. Wt.] within few seconds while the display is flashing. If no action is initiated within a few seconds, the "Unit Weight” display will revert to the previous value, otherwise it will show the new value that has been entered. • The sample is then added to the scale and the weight will be displa

6.3.4 Count pre-set or check-weighing Check-weighing (or Count Pre-setting) is a procedure to cause an alarm to sound when the net weight (or the number of items) on the scale meets or exceeds a number stored in memory. The value to be stored is entered from the keyboard. SETTING OF PRESET LIMITS It is possible to set a high and low limit for either counting or weighing (using net weight). When the [Pst] key is pressed the user can select either counting or weighing and th

6.4 PLU (Product Look Up) Product Look-Up (PLU) numbers are used to store information about the commonly used items. The Tare Weight, Description of the product and Unit Weights for a particular item are recalled by entering the PLU number for ease of operation. The scale is capable of storing values for the Tare weight, Description and Unit Weight for a maximum of up to 100 PLU numbers. Tare Weight value is required for calculating the Net Weight where a container is used
