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.
• 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.

3.2 SETTING UP THE SCALES
SETTING UP THE LOCAL SCALE

• The CDT 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  our 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 (CDT 8, where 8 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 CDT 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:

(The sense wires connections of a six wire load cell are not used and should be connected to the respective Excitation pins).

3.3 REMOTE 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 14 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.

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 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.

DISPLAYS

The scales have three display windows- Weight, Unit Weight and Count.

5.1 WEIGHT 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”
  

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, 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.
5.3 COUNT 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.

OPERATION

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.
The switch from local scale to remote scale should be possible at any time by pressing the [Local/Rem] key.
NOTE: For frequently used items, counting is made easier by using PLU numbers (Product Look Up). Up to 100 PLU’s can be stored and recalled. Place the item on the pan and enter the appropriate PLU number using the keypad. The scale will display the Total Weight, Unit weight and the Count of the item in the respective windows. See section 7.4.
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 indicator at “Zero”.
The scale has an automatic re-zeroing function to account for minor drifting or accumulation of material on the platform. However you may need to press the [Tare/Zero] to re-zero the scale if small amounts of weight are still shown even when the platform is empty.
TARING
Preset tare values can be used with both the local and remote scale. If a new tare value is to be used, there are two methods for entering a tare value. The first method uses the weight on the platform and the second uses a value to be entered by the user.
FIRST METHOD OF ENTERING A TARE VALUE:

• Zero the scale by pressing the [Tare/Zero] key, if necessary. The arrow indicator over “Zero” will be on.
• Place a container on the platform, a value for its weight will be displayed.
• Press the [Tare/Zero] key to tare the scale. The weight that was displayed is stored as the tare value and that value is subtracted from the display, leaving zero on the display. The arrow over “Net” will be on. As product is added only the net weight of the product will be shown. The scale could be tared a second time if another type of product was to be added to the first one. Again only the weight that is added after taring will be displayed.
• 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 those 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 if all containers are the same or if the container is already full but the net weight is required and the weight of the container is known.
• Remove all weights from the platform, press the [Tare/Zero] key to zero the display.
• Enter the value for the Tare weight including decimal point using the keypad, press [Tare/Zero] to store the tare value. The weight will show a negative value equal to  the tare.
• Place the container on the platform.
• The display will then show the weight of the container minus the tare weight. When the full container is placed on the platform the tare value will be subtracted from  the gross weight displaying only the net weight of the contents.
• If the value input is not consistent with the increment of the scale, the scale will round the tare value to the nearest value possible. For example, if a tare value of 103g is  entered into the 60Kg scale with 5g readability, then the display will show -105g.
• The tare value for each scale is held in memory so that they are not lost when the active scale changes.

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 items have been added to the accumulation memory. The values will be displayed for 2 seconds before returning to normal.
The scale must return to zero or a negative number before another sample can be added to the memory.
More products can then be added and the [M+] key pressed again. This can continue for up to 99 entries or until the capacity of the “Weight” display is exceeded.
To observe the total value stored, press the [M+] key when the scale is at zero. The total will be displayed for 2 seconds.
To clear the memory, first press [M+] to recall the total from the memory and then press [CE] to clear all values from the memory.
6.2.2 AUTOMATIC ACCUMULATED TOTAL
The scale can be set to automatically accumulate total when a weight is placed on the scale. This eliminates the need to press the [M+] key to store values into the memory. However the [M+] key is still active and can be pressed to store the values immediately. In this case, the values will not be stored when the scale returns to zero.
See Section 7 for enabling Automatic Accumulation.
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 count using either of the scales.
It is possible to increase the accuracy of the unit weight at any time during the counting process by entering the count displayed and then pressing the [Smpl] key. You must ensure that the quantity displayed matches the quantity on the scale before pressing the key. The unit weight can be adjusted based on a larger sample quantity. This will give greater accuracy when counting larger sample sizes.
6.3.1 WEIGHING A SAMPLE TO DETERMINE THE UNIT WEIGHT
To determine the average weight of the items to be counted place a known quantity of the items on the scale and then enter the quantity being weighed. The scale will then divide the total weight by the number of samples and display the average unit weight.

• Zero the scale by pressing the [Zero] key if necessary. If a container is to be used, place the container on the scale and tare as discussed earlier.
• Place a known quantity of items on the scale. After the “Weight” display is stable enter the quantity of items using the numeric keys followed by pressing the [Smpl] key. The number of units will be displayed on the “Count” display and the computed average weight will be shown on the “Unit Weight” display.
• As more items are added to the scale, the weight and the count will increase.
• If the scale is not stable, the calculation will not be completed.
• If the weight is below zero, the “Count” display will show negative count.

6.3.2 ENTERING A KNOWN UNIT WEIGHT
If the unit weight is already known then it can be entered using the keypad.
Enter the value of the unit weight using the numeric keys followed by pressing the [U. Wt.] key 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 displayed as well as the quantity based upon the unit weight. When weighing in kilograms the unit weight is shown in grams. When weighing in pounds the unit weight is shown in pounds.
After the unit weight has been determined or entered, the scale can be used for parts counting.
The scale may be tared to account for the net weight as discussed in an earlier section.
After the scale is tared, the items to be counted are added and the “Count” display will show the number of items computed using the weight and the unit weight.
It is possible to increase the accuracy of the unit weight at any time during the counting process by manually entering the sample quantity and then pressing the [Smpl] key. You must ensure that the quantity displayed matches the quantity on the scale before pressing the key. The unit weight will be adjusted based upon a larger sample quantity. This will give greater accuracy when counting larger sample sizes.
6.3.3 AUTOMATIC UPDATE OF UNIT WEIGHT
The scales will automatically update the unit weight when a sample less than the initial sample count is added. A beep will be heard when the value is updated. It is wise to  check the quantity is correct when the unit weight has been updated automatically.
To lock the unit weight and prevent Auto-update, press [U.Wt.].
This feature is turned off as soon as the number of items added exceeds the count used as a sample.
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 then set the lower and upper limit.
For example:

displayed, press [CE] to clear and change if needed.
If using net weight the display will show “Hi WEG”
Press [Print]| “lo cnt” “0.0 2 3 4″ ” ” The current low count limit is displayed, press [CE] to clear and change if needed.
If using net weight the display will show “Lo WEG”
Press [Print]| Return to weighing with limits set.

Clearing of either or both the limits is allowed. Both limits cleared will disable the Preset altogether.
If Preset Weight was selected the first display would show “Hi WEG” and “Lo WEG”.
The beeper will work as described in the Beeper Parameter.
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 during weighing. Descriptions are used for sending data over RS-232 for viewing or printing and Unit Weight is used for parts counting.
These data should be entered against a particular PLU before the weighing process starts so that the desired PLU’s can be recalled during the weighing process. The data can be stored and recalled manually or by sending data over RS-232 Interface.
6.4.1 STORING PLU’S MANUALLY

Note:
Enter or determine the Tare Weight when a container is to be used (see section 6.1 of this User Manual). If a Tare value is used, the scale will be in the NET mode.
Enter or determine the Unit Weight as described in section 6.3.1 and 6.3.2 of this User Manual.
The Tare and Unit Weight to be stored can be either taken from a weighing in process or by manual entry of data.
Please find below an example for setting up “PLU 27” with Description as “M4 Nut” and Unit weight of “0.015”.

shown with the first character flashing. The flashing digit can be
changed as stated in the Note below.
Pressing the [CE] key when the first character is flashing will clear all the descriptions.| “PLU 27 “| „ „| „ „| –
Continue to enter characters until description is complete.| “PLU 27 “| “M 4 Nut”| “Brass “| 12 characters in total spreading over both the displays (UNIT WEIGHT and COUNT).
Press [Print] to save the PLU.| ” STOrE”| “PLU “| ” 27 “| The display will show the PLU is saved then return to normal weighing mode.

Note:
Use the [.] key to go back to the previous digit or the [M+] key to advance to the next character.
A flashing character can be used for entering a space by pressing the [0] key for slightly longer duration.
Tare value will only be stored with PLU data if the scale is in the NET mode. If the container is less then the manual zero range which is set in “Technical parameters”  (default is 2% of capacity) then the scale will be Zeroed and no tare value will be stored. To avoid this, use a larger container, reduce the zero range or use the digital tare method.
6.4.2 ENTERING DESCRIPTION MANUALLY
The description can be up to 12 characters long and can be a mix of numbers, symbols or letters.
During the procedure to set the description the numeric keypad will work in a similar way to a mobile telephone. Pressing a number briefly will show the number and holding it down will scroll through all the characters.
The numbers and characters are:
1 – / \
2 A B C
3 D E F
4 G H I
5 J K L
6 M N O
7 P Q R S
8 T U V
9 W X Y Z
0 [ ] Where _ is a Space (Not underscore)
The limitations of the 7 segment display sometimes make it difficult to display some letters. The characters and the displayed symbols are:

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z – / \ ( )

The characters will be stored as text so the output of the RS-232 interface will look correct.
The numbers 1 2 3 4 5 6 7 8 9 0 will be 1 2 3 4 5 6 7 8 9 0.
Note that this method is only used where alpha-numeric data is permitted. This is used for the Description field and the User ID number, Scale ID number in the parameters section.
6.4.3 RECALLING PLU’S MANUALLY
To recall the PLU values the user should first select either local or remote scale as the tare value stored will be specific to the scale selected.
Then press the [PLU] key, enter the PLU number (00 – 99) then press the [PLU] key again to recall the data.
The display will show the results of the recall for 1 second then return to weighing with the data in place.
For example:

After 1 second, it will return to normal weighing with the Tare and Unit Weight previously entered.| ” x x x x”| “xxxx “| ” x x”

If the [PLU] key is held down after the numeric entry, it will show the description as long as the key is pressed.
In this example the display “PLU 27 ” “M 4 Nut“ “Brass “ shows the description for 1 second, if no data is stored then it will show “nO ” “ PLU “ “SAVE “.
If the tare value is outside the range permitted for the selected scale (For example, if the local scale is selected whereas the tare value applies to the remote scale, this would  exceed the capacity of the local scale) the “Weight” display would show zero tare weight.
If the tare value stored does not match the increment of the selected scale (For example, storing 1.446 for a scale with d=0.05) then round the tare weight depending on the scale resolution (For example, in this case, -1.45 would be used as the tare value).
If a PLU number is recalled that does not have any information stored against it, the scale  will continue to work with Tare and Unit weight unchanged.
NOTE: PLU’s can be stored and recalled using RS-232 Interface (see section 9.1 to 9.3 of this user Manual).

  “m-d-Y” month, day, year
  “d-m-Y” day, month, year
  The Unit Weight display will show the current format, “Y-m-d” for example.

• Press the [Tare] key to accept the chosen format, the Count display will show the current settings. Enter the date in this format.

• Press the [CE] key to clear the current setting then enter the new values.

• Press the [Tare] key to accept the date.

An error code will be shown if the time (Err 1) or the date (Err 2) is not the permissible values. For example, 34 day of a month is an invalid entry.
Pressing the [Zero] key will escape for the date and time settings with the current values unchanged. It is possible to change only the time by setting a new time, then pressing the [Zero] key when the date settings are shown.

BATTERY OPERATION

The scales can be operated from the battery. The battery life is approximately 70 hours if only the basic unit is used and the backlight is not used. If the backlight and a  second platform is used the battery life will be reduced.
When the battery needs charging the arrow above the low battery symbol under the “Weight” display will turn on. The battery should be charged as soon as the arrow above  the symbol is on.
The scale will still operate for about 10 hours after which it will automatically switch off to protect the battery.
To charge the battery simply plug into the mains power. The scale need not to be turned on.
The battery should be charged for 12 hours for full capacity.
Just under the “Count” display is an LED to indicate the status of 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 is nearly discharged and yellow indicates the battery is nearly charged.

9.1 INPUT COMMANDS FORMAT
The scale can be controlled with the following commands.
Input Commands:

• The scale has a number of commands to either cause an action or to enter data into memory. The commands are all upper case and are summarised below.
• All commands are terminated by a carriage return (Enter button on PC keyboard) with the line feed optional.
• If an illegal command is received or a command cannot be carried out then send the command back with the addition of ER in front of it. For example if the command is NN send back ER NN.

Basic Commands:

currently in pounds)
S123| Enter sample size of 123 parts. Same as pressing [Smpl] key.
SL| Select local scale to be used
SR| Select remote scale to be used

Immediate Printing Commands:

9.2 STORING DATA VIA RS232
To store data the commands are:

When PLU text data is stored the Scale stores current unit weight and current tare value along with the PLU number.
For the SPLU command the data is: PLU number (2 characters), (Comma) description (max 12 characters).
If the fields are less than the maximum all characters need not be used.
9.3 PLU ENTRY USING RS-232 INTERFACE
This method enables the user to send the data from a PC program as well as from the keypad. The most common PLUs can be stored and recalled from the scale memory. Other PLU data can be stored on a PC, then the Description (text data), Unit Weight and Tare Weight data can be sent from the PC for the PLUxx (where xx can be any desired number up to 99). This can then be used or over- written during operation.
OPERATION:

• Send Tare Weight data to set any tare value to be stored with PLU.
  i.e. “T 1.45” . If no tare is needed then you may send “T 0” to delete any present tare data.

• Send the Unit Weight to be stored with PLU. i.e. “U0.015”

• Send PLU text data to be stored with current Tare and U/W values.
  i.e. “SPLU27, M4 Nut Brass”

Any information stored for the Tare Weight, Description and the Unit weight will be stored in the scale and can be recalled for use in the future.
