4.0INSTALLATION
4.1LOCATING 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.
∙Avoid high humidity that might cause condensation. Avoid direct contact with water. Do not spray or immerse the scales in water.
∙Avoid air movement such as from fans or opening doors. Do not place near open windows or airconditioning vents.
∙Keep the scales clean. Do not stack material on the scales when they are not in use.

4.2SETTING UP THE SCALES
SETTING UP THE LOCAL SCALE
∙The CBD Series comes with a stainless steel platform packed separately.
∙Place the platform in the locating holes on the top cover.
∙Do not press with excessive force as this could damage the load cell inside.
∙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.
∙AC powered scales, attach the power cable to the connector on the bottom of the scale base. If using the external plug in power supply module (USA) connect it to the socket on the side.
∙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 (CBD 15, where 15 denotes the maximum capacity of the scale in Kg) and the current software revision number in the “Unit Weight” display window.
∙Next a self-test is followed. At the end of the self-test, it will display “zero weight and zero values in all three displays. If the weight display shows a value it was not possible to set a new zero during power on.
SETTING UP THE REMOTE SCALE
∙The CBD Series can be connected to any size of load cell type weighing base via the Remote scale port on the right side of the scale case. Ensure you have the correct base for the scale as each is matched for calibration.
∙Place the remote scale platform in the position where it is to be used. Level the scale by adjusting the four feet. If fitted with a spirit level then it should be adjusted such that the bubble is in the centre.
∙Press [Local/Rem] to select the local scale or the remote base for configuration and operation.

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 and should be connected to the respective Excitation pins).
4.3REMOTE SCALE SET UP
The remote scale should set for a realistic resolution with respect to the input provided by the load cell/s. See Section 13 for details of configuring the remote scale.
If a single 2 mV / V load cell is fitted and more than 60% of the load cell is used for full capacity then the high output of >6 mV span makes it possible to set a high resolution.
If this criterion is met then the remote scale can be set to a high resolution with a maximum of 1:30,000, i.e. 300 kg x 0.01 kg.
Where more than one load cell is fitted or the total load cell capacity is not utilised then a reduced resolution should be selected in the remote scale technical set up. For example, if a system uses four 2 mV / V 1000 kg load cells for a scale of 1000 kg capacity then the span output at full scale will be only 2.5 mV.
In this situation the resolution should be reduced to give a good number of ADC counts per displayed division. ie. Set to 1:5000 or 1000 kg x 0.2 kg.
Setting a high resolution without providing a good input to the remote scale ADC will not give better accuracy and may make the scale difficult to meet performance specification.

5.0KEY 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 scale. Up to 99 values or full capacity of the weight display can be added. Also prints the displayed values when Auto print is switched off.
[Smpl]
This is used to enter the number of items of a sample.
[PLU]
To store and recall the Product Look Up sample information.
[U. Wt./Units]
This key is used to enter the weight of a sample manually. It will also change the weighing units when other units are enabled.
[PST]
To set the upper limit for the number of items counted. When this upper limit is exceeded the scale will sound the beeper. A secondary function is to use it access the menus for user settings.
[Print]
It is used to print the weighing data.
[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.

6.0DISPLAYS
The scales have three display windows- Weight, Unit Weight and Count.
6.1WEIGHT WINDOW
This consists of a 6 digit display to indicate the weight on the scale.
An arrow above the symbols will indicate the following:
Low battery,
Net Weight Display, "Net"
Stability indicator, “Stable”
Zero indicator, “Zero”
Unit in use indicator, “Lb” or “Kg”
6.2UNIT 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, the arrow will show at "U.Wt".
When a value has been entered into the memory, the arrow above "M+" will be on.
In both the cases the scale continues to operate and the indicators are to alert the user of a potential problem.

10 |
6.3COUNT WINDOW
This display will show the number of items on the scale or the value of the accumulated count. See the OPERATION section.
An arrow above the symbols will indicate the following:
|
Checkweighing is active during counting, "Ck Pcs" |
|
Checkweighing is active during weighing, “Ck Wt” |
Checkweighing is active, result is above the High Limit, “High”
Checkweighing is active, result is between the Low and High Limit, “OK”
Checkweighing is active, result is below the Low Limit, “Low”
Just under the “Count” display is an LED to indicate the status of the battery charging. When the scale is plugged into the main power the internal battery will be charged. If the LED is green, the battery has a full charge. If it is red, the battery requires further charging and yellow indicates the battery is being charged.
7.0OPERATION
The basic weighing functions are same for both the local and remote scales. 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 weighing and counting a sample on the local scale which may have the best sensitivity. Then the scale can be switched to the remote where large quantities can be counted.
Each scale has a separate tare value that can be entered through the keypad or by placing a weight on the platform and pressing the [Tare/Zero] key. The tare value for each scale is retained as the user switches between the remote and local scales.
Either scale can be used to determine a unit weight.
When the scale is switched from local to remote, a clear display will be shown to identify the change and the scales will count based on the tare and unit weight currently in use for the scale selected. Display for the change is:
“c h A n g E” ”L o c A L“ and “c h A n g E” ”r e m o t E “
The display will be based on the 7 segment interpretations, some of the letters are shown later.
