4. Setting Up the Scale

4.1 Setting Up the Local Scale

1. Carefully remove the scale and accessories from the box.
2. Remove any transportation aids before starting work with the scale. The transport lock is located on the underside of the scale.
3. Place the scale on a stable and level surface. Do not place the scale on a wobbly or vibrating tabletop to prevent incorrect measurement results.
4. Do not set up the scale near vibrating equipment.
5. Align the scale parallel to the tabletop using the four adjustable feet (the air bubble should be in the center of the bubble level).
6. Remove the weighing platform from the separate packaging and carefully fit it into the holes on the top of the scale.
7. Plug the power cord into the socket on the bottom of the scale. Switch on the scale. The on/off switch is located on the bottom right-hand side of the housing. When switching on the scale, make sure the weighing platform is empty. The scale runs a switch-on routine and confirms the end of the initialization process with a beep.

If there are any items on the weighing platform during the initialization process, the scale may function incorrectly. Switch the scale off and repeat the switch-on routine.

1. The scale is now ready for use.
2. Place the load in the center of the weighing platform to ensure accurate measurement results. Ensure the load does not protrude beyond the weighing platform.

4.2 Setting Up the Remote Scale

The ZW50 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 housing. Ensure you have the correct base for the scale, as each is matched for calibration.

Place the remote scale in the position where it is to be used and level it by adjusting the four feet and using the bubble level.

Press the key and test the weighing settings.

The cable for the load cell goes to a 9-pin D-Sub connector with the following connections:

Pin	Connection
1, 2	Ex+ Sen+ (5 V)
4, 5	Ex- Sen- (0 V)
7	Signal-
8	Signal+

• The sense wires connections of a 6-wire load cell are not used and should be connected to the respective excitation pins.
• The remote scale should be set for a realistic resolution with respect to the input voltage of the load cells.
• If a single 2 mV/V load cell is fitted and more than 60% of the load cell is used for full capacity, the high output span of >6 mV makes it possible to set a high resolution. If this criterion is met, the remote scale can be set to a high resolution with a maximum of 1:30,000, e.g., 10 g at 300 kg. This means that the remote scale can have the same accuracy as the local scale.
• Where more than one load cell is fitted or the total load cell capacity is not utilized, then a reduced resolution should be selected in the remote scale technical setup.
• For example, if a system uses four 2 mV/V 1000 kg load cells for a scale of 1000 kg capacity, the span output at full scale will be only 2.5 mV. In this case, the resolution should be reduced to give a good number of A/D counts per displayed division, e.g., set to 1:5000 or 0.2 kg at 1000 kg.
• Setting a high resolution without providing a good input to the remote scale ADC will not give better accuracy and may prevent the scale from meeting performance specifications.

• For optimal performance, ensure a minimum of 0.1 V / d .

8. Operation

8.1 General

Both the local and remote scales have the same basic weighing functions. Because of its technical specifications, however, the resolution of the remote scale may differ from that of the local scale.

Each scale (local or remote) has the ability to count pieces based on the current unit weight. Given its higher sensitivity compared to the remote scale, we recommend using the local scale for counting samples and the remote scale for counting larger quantities.

Each of the scales can be tared separately. This offers a particular advantage when using different sorting containers (a small container for the samples and a large container for the pieces to be counted).

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. The "Weight" and "Unit Weight" displays indicate the changeover with "CHANGE LOCAL" or "CHANGE REMOTE."

You can toggle between the local and remote scales at any time using the key, or, provided the respective function is activated, the system automatically switches to the remote scale if the negative weight on the remote scale changes to a positive value exceeding 50d. For frequently used items, counting is made easier by using PLU numbers. Up to 100 PLUs can be saved and retrieved (see the "PLU" section below).

8.2 Switching On the Scale

The on/off switch is located on the bottom right-hand side of the housing.

When switching on the scale, make sure the weighing platform is empty. The scale runs a switch-on routine and confirms the end of the initialization process with a beep. The scale is now ready for use.

If there are any items on the weighing platform during the initialization process, the scale may function incorrectly.

Switch the scale off and repeat the switch-on routine.

8.3 Zeroing the Display

When the gross weight is within ± 2% of the zero, set at power on for either scale; then a new zero is set. The system executes the tare function when the gross weight is greater than ± 2% .

• You can press the key at any time to set the zero point from which all other weighing and counting operations are performed. Zeroing is normally required only when the weighing platform is empty. When the zero point is obtained, the “Weight” display will show the arrow indicator at 0
• 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 -0- key to re-zero the scale if small amounts of weight are still shown even when the weighing platform is empty.

8.4 Taring

Select the local or remote scale as required by pressing the key. Preset tare values can be used for the local scale 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 weighing platform, and the second uses a value to be entered by the user.

8.4.1 Method 1:

• Zero the scale by pressing the -0- key if necessary. The arrow indicator above the 0 symbol will be on. Place a container on the weighing platform. The display will show its weight.
• Press the 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 indicator above “Net” will be on.
• As the product is added, only the net weight of the product will be shown. The scale can be tared a second time if another type of product is to be added to the first one. The process can go on until the capacity is reached.
• After removing the container, the display shows a negative value. If the scale was tared just before removing the container, this value is the gross weight of the container plus the weight of all products that were removed. The arrow indicator above the symbol will also

be on because the weighing platform is back to the same condition as it was when the key was last pressed.

8.4.2 Method 2:

This method implies manually entering the tare weight using the keypad. This option is especially useful when all containers are the same or when you need to know the net weight for the container that is already full and whose weight is known.

- Remove all items from the weighing platform and press the -0 - key to zero the display. Enter the tare weight (including the decimal point) using the keypad and save it by pressing the key. The display will show the negative weight value equal to the tare value.

• Place the container on the weighing platform.
• The display will show the weight of the container minus the tare weight.
• When the full container is placed on the weighing platform, the tare value will be subtracted from the gross weight, displaying only the net weight of the contents.
• If the input value 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 values for each scale are held in memory so that they are not lost when changing between the remote and local scales.

8.4.3 Taring the Remote Scale

Select the remote scale by pressing the above.

Then, follow the procedure as described

8.5 Determining / Entering the Unit Weight

In order to do piece counting, it is necessary to know the average weight of the items to be counted. If the unit weight is already known, you can enter it manually using the keypad. Alternatively, you can weigh a known number of the items and let the scale determine the average unit weight.

8.5.1 Determining the Unit Weight

The basic functions for piece counting are the same for the local and remote scales.

In order to perform piece 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.

8.5.2 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 key if necessary. If a container is to be used, place the container on the scale and tare as explained 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 key.

- The number of units will be shown in the "Count" display, and the computed average weight will be shown in the "Unit Weight" display.

- As more items are added to the scale, the weight and the count will increase.

- If the quantity of items placed on the scale is lower than the reference, the scale will recompute the unit weight and increase it. To lock the unit weight and prevent automatic recom-

putation, press the key.

- If the scale is not stable, the calculation will not be completed. If the weight is below zero, the "Count" display will show a negative count.

8.5.3 Entering a Known Unit Weight

If the unit weight is already known, it can be entered using the keypad.

• Enter the value for the unit weight using the numeric keys followed by pressing the key. The "Unit Weight" display will indicate the value you have entered.

- Place the pieces to be counted on the weighing surface. The display will show the weight and the quantity based on the unit weight. When weighing in kilograms (kg), the unit weight is shown in grams. When weighing in pounds (lb), the unit weight is shown in pounds.

8.5.4 Automatic Update of Unit Weight

The scale will automatically update the unit weight when a sample less than the initial sample count is added. The scale beeps 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 automatic update, press the key.

This feature is turned off as soon as the number of items added exceeds the count used as a sample.

8.6 Piece Counting

After the unit weight has been determined or entered, the scale can be used for piece counting. The scale can be tared to account for the net weight, as explained in the previous section.

- With the scale tared, place the pieces to be counted on the weighing platform. The "Count" display will show the number of pieces computed using the total 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 key. The unit weight can be adjusted based on a larger sample quantity. This will give greater accuracy when counting larger sample sizes.

8.7 Check Weighing

The scale has a check weighing function applicable to both weighing and counting modes. Depending on the criteria met, the "Count" display then shows an arrow above HIGH, OK, or LOW. This check weighing function is supported by an acoustic alarm.

8.7.1 Check Weighing in Counting Mode / Setting the Upper And Lower Limits

Pressing the key activates the check weighing function in counting mode. Press the

key to switch to "Cnt" and confirm your selection with the key.

- The "Weight" display will now show HI CNT. Enter the upper limit for a quantity at which an acoustic alarm should sound using the 10-key keypad and confirm with the key.

- The "Weight" display will now show LO CNT. Enter the lower limit for a quantity at which an acoustic alarm should sound using the 10-key keypad and confirm with the key.

- The system takes you back to weighing mode.

- The arrow indicator above Ck Pcs in the "Count" display indicates that the function is activated.

- Also, depending on the criteria met, the corresponding arrow indicator will light up above HIGH, OK, or LOW in the "Count" display.

IMPORTANT: Saving the value "0" deactivates the check weighing function.

8.7.2 Check Weighing in Weighing Mode / Setting the Upper And Lower Limits

Pressing the key activates the check weighing function in weighing mode. Press the

key to switch to "nEt" and confirm your selection with the key.

- The "Weight" display will now show HI NET. Enter the upper limit for a weight at which an acoustic alarm should sound using the 10-key keypad and confirm with the key.

- The "Weight" display will now show LO NET. Enter the lower limit for the weight at which an acoustic alarm should sound using the 10-key keypad and confirm with the key.

- The system takes you back to weighing mode.

- The arrow indicator above Ck Wt in the "Count" display indicates that the function is activated.

- Also, depending on the criteria met, the corresponding arrow indicator will light up above HIGH, OK, or LOW in the "Count" display.

IMPORTANT: Saving the value "0" deactivates the check weighing function.

8.7.3 Acoustic Alarm Function

The check weighing function is supported by an acoustic alarm. From the parameter settings menu (chapter 9), the following alarm options can be selected under "F1 oFF" in the "bEEP" subparameter. The scale is preset to "bEEP oFF" by default.

“bEEP oFF”	The beeper is set to off.
“bEEP on in”	The beeper is set to on between limits.
“bEEP on out”	The beeper is set to on outside limits.

8.8 Summation Memory

8.8.1 Manual Summation Memory

• The values (weight and count) shown on the display can be added to the values in the
  memory by pressing the key, no matter whether you are using the local scale or remote scale. The "Weight" display will show the total weight. The "Count" display will show the total accumulated count. The "Unit Weight" display will show the number of times items have been added to the summation memory. The values will be displayed for 2 seconds before the scale returns to normal weighing mode.
• The scale must return to zero or a negative number before another sample can be added to the memory.
• You can also add more products by pressing the M+ key. This process can go on up to
• 99 entries or until the capacity of the "Weight" display is exceeded.
• To observe the total value stored, press the key. The total will be displayed for 2 seconds.
• To clear the memory, press the M+ key to recall the total from the memory and
• then press the key to clear all values from the memory.

8.8.2 Automatic Summation Memory

- The scale can be set to automatically accumulate total when a weight is placed on the scale.

This eliminates the need to press the key to store values in the memory. However, the 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 resets to zero.

- See section 9 (Parameters) for enabling automatic summation.

8.9 PLU (Product Look Up)

The ZW50 scale has the capacity to store 100 PLU (Product Look Up) numbers (00-99). The PLU numbers are used to store information about the commonly used items, such as tare weights, average unit weights, and description of the item. This data can be retrieved quickly and easily by entering a PLU number. The PLU number can be assigned the tare weight with additional text, piece weight with additional text, or additional text only.

The tare weight is required for calculating the net weight where a container is used during weighing. Product descriptions are used for sending data over the RS-232 data interface for viewing (PC) or printing (printer), and the 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 PLUs can be recalled during the weighing process.

8.9.1 Storing PLUs Manually

Tare weight:

If the scale is used in counting mode, check whether the quantity or counting scale needs to be tared. Select the quantity or reference scale accordingly.

• Press the -0- key if necessary. All three displays will show zero (0).
• Tare the container as described under 8.4.1 above, for example, by placing the container
  on the scale and pressing the key, or enter the tare weight manually using the keypad (see 8.4.2). The scale will be in the Net mode.

Piece weight:

If the scale is used in counting mode, select the reference scale.

- Determine the piece weight (see 8.5.2) or, if it is known, enter the piece weight directly (see

8.5.3) using the keypad and then press the key.

The further procedure is the same for tare and piece weight:

• To save under a specific PLU, press the key and the corresponding PLU number. There are a total of 100 PLUs (00 to 99).

Example:

Below is an example of how to set up "PLU 27" with the description "M4 Brass Screw":

Key(s) to press	Weight display	Unit Weight display	Count display	Remarks
	“PLU”	“- - ”	“ ”
2, 7	“PLU”	“27”	“ ”
	“PLU 27”	“x x x x x x”	“x x x”	The current description will be shown with the first character flashing. This character can be entered using the numeric keypad.
With the first character flashing, pressing the years all the descriptions.	“PLU 27”	“ ”	“ ”
Continue entering characters until the description is complete.	“PLU 27”	“M4SCHR”	“MESSIN”	12 characters in total spreading over both displays (Unit Weight and Count).

Enter the additional texts as described in 8.6.2.

Confirm entries with the key. The data will be stored in the PLU number entered.

Notes:

• Use the key to go back to the previous character or the key to advance to the next character.
• While the character is flashing, press and hold the key a little longer to enter a space.
• Tare values will only be stored with PLU data while the scale is in the Net mode.
• Where the weight of the container is less than the automatic zero range (2% of capacity by default), the scale will be zeroed automatically, and no tare weight will be stored. This can be avoided by using a heavier container, changing the zero range, or using the digital tare method.

8.9.2 Entering Description Manually

The description of an item can be up to 12 characters long and can be a mix of numbers, symbols, and letters. When entering the item description, the numeric keypad works in a similar way to a mobile telephone.

Pressing a key briefly shows the number, and holding the key down scrolls through all the characters. Pressing and holding the key displays in succession all the numbers and characters assigned to the respective key.

The numbers and characters are shown below:

Key	Character	Key	Character
1	- / \	6	M N O
2	A B C	7	P Q R S
3	D E F	8	T U V
4	G H I	9	W X Y Z

	“PLU”	“- -”	“ ”
2, 7	“PLU”	“27”	“ ”
[B7TW]	“PLU 27”	“M4SCHR”	“MESSIN”
After one second, the display will return to normal weighing mode with the tare and piece weight values previously entered.	“× × × ×”	“× × × ×”	“× ×”

Notes:

PLU

• If the key is held down after the numeric entry, the display will show the description as long as the key is pressed.
• In the example, the display shows "PLU 27" "M4SCHR" "MESSIN" for one second; if no data is stored, the display will show "PLU 27" " " "".
• If the tare weight value is outside the range permitted for the selected scale (for example, if the local scale is selected, whereas the tare weight applies to the remote scale, the capacity of the local scale will be exceeded), the "Weight" display will show zero tare weight.
• If the tare weight value stored does not match the increment of the selected scale (for example, storing -1.446 for a scale with d = 0.05 ), the tare weight should be rounded depending on the scale resolution (for example, in this case, -1.45 will 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 the tare and unit weight values unchanged.

9. Parameters

The parameters can be set by calling up a secure menu. The parameters are divided into two sections. One section is for the user, and the other is for the authorized technician.

• To enter the user parameters section, press the key during the self-test after switching on the scale.
• Press the key to scroll through the main parameters. The "Weight" display shows the names of the parameters.

- To select any parameter, press the key.

- Press the key to scroll through the sub-parameters.

- Press the key to save your selection.

- You can exit a sub-parameter at any time by pressing the key. Pressing this key several times takes you back to weighing mode.
