3.0 INSTALLATION

3.1 UNPACKING

This indicator must be connected to a load cell platform and calibrated as necessary to match the platform and user requirements. See Section 12.0 for set-up information.

The user’s application and the technical specifications of the platform or load cell will determine the necessary configuration.

3.2 LOCATING

• 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 air-conditioning vents.

• Keep the scales clean. Do not stack material on

the scales when they are not in use.

P a g e 6 © Adam Equipment Company 2010

3.3 CONNECTION

This indicator must be connected to a load cell platform and calibrated as necessary to match the platform and user requirements.

The GC has a connector configured for either 4 or 6 wire load cells. Connect the load cells/platform to the indicator as shown below. The cable length should be as short as possible, using a large size wire to minimise errors due to resistance in the leads.

Figure 1A shows the connections to a 6 wire load cell. Figure 1B and 1C show 2 different ways to attach a 4 wire load cell, 1B uses a 6 conductor cable to go from the indicator to the platform or load cell where it connects to the 4 wires from the load cells.

The Excitation and sense wires are connected internally in the GC indicator.

5.2 UNIT WEIGHT DISPLAY

This display will show the unit weight of a sample. This value is either input by the user or computed by the scale. The unit of measurement is grams if grams if kilograms is selected for the weighing unit, or pounds if pounds is selected.

5.3 COUNT DISPLAY

This display will show the number of items on the scale or the value of the accumulated count. See the next section on OPERATION.

5.4 OTHER SYMBOLS

• The symbol, when there is insufficient number of samples to

accurately determine the count.

• When the unit weight is not large enough to determine an accurate count,

the symbol will be on.

• In both cases the scale continues to operate and the indications are to

alert the user for a potential problem.

• If a preset count has been stored the symbol will be on.

• A low battery symbol will turn on if the battery should be recharged.

• The Lo, OK, Hi symbols will be used when the preset count has been set.

• The symbol “Mem” will be seen when the internal memory has a record of

previous weighings stored in it.

P a g e 10 © Adam Equipment Company 2010

6.0 OPERATION

NOTE: GC-a Scales only

SETTING THE WEIGHING UNIT, lb or kg

The scale will turn on displaying the last weighing unit selected, either kilograms or pounds. To change the weighing unit press the [U. Wt./Units] key when the “Unit Weight” display shows zero. If necessary press the [CE] key to clear the unit weight before changing.

6.1 ZEROING THE DISPLAY

• You can press the [Zero] key at any time to set the zero point from which

all other weighing and counting is measured. This will usually be necessary only when the platform is empty. When the zero point is obtained the “Weight” display will show the indicator for zero, “>Z<”.

• 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 [Zero] to re-zero the scale if small amounts of weight are still shown when the platform is empty.

6.2 TARING

• Zero the scale by pressing the [Zero] key if necessary. The indicator

“>Z<” will be ON.

• Place a container on the platform and its weight will be displayed.

• Press [Tare] to tare the scale. The weight that was displayed is stored as

the tare value which is subtracted from the display, leaving zero on the display. The indicators “Net” and “>Z<” will be ON.

• As a product is added only the 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 indicator “>Z<” will also be ON because the platform is back to the same condition as it was when the [Zero] key was pressed last.

P a g e 11 © Adam Equipment Company 2010

6.2.1 Preset Tare

• The user can enter a preset tare value if the display is at zero or gross

weight. Enter the value for preset tare using the keypad, then press the [Tare] key to set the preset zero value.

• If the display was at zero the weight will show a negative value equal to

the preset tare value entered and the “Net” indicator will be on. If a weight was on the platform then the preset value will be subtracted from the weight, displaying the NET weight only.

6.3 PARTS COUNTING

6.3.1 Setting Unit Weight

In order to do parts counting it is necessary to know the average weight of the items to be counted. This can be done 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.

A. Weighing a sample to determine the Unit Weight

To determine the average weight of the items to be counted, you will need to place a known quantity of the items on the scale and then to key in the number of items being weighed. The scale will then divide the total weight by the number of items and display the average unit weight. Press [CE] anytime to clear the 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 by pressing [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 and then press 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 quantity will

increase.

• If a quantity which is smaller than the sample is placed on the scale,

then the scale will automatically enhance the Unit Weight by recalculating it. To lock the Unit Weight and avoid re-sampling, press [U.

Wt./Units].

P a g e 12 © Adam Equipment Company 2010

• 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.

B. Entering a known Unit Weight

• If the unit weight is already known then it is possible to enter that value

using the keypad.

• Enter the value of the unit weight in grams, using the numeric keys

followed by pressing the [U. Wt./Units] key. The "Unit Weight" display will show the value as it was entered.

• The sample is then added to the scale and the weight will be displayed

as well as the quantity, based on the unit weight.

6.3.2 Counting more parts

• After the unit weight has been determined or entered, it is possible to

use the scale for parts counting. The scale can be tared to account for the container weight as discussed in the 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 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 entering the count displayed and then pressing the [Smpl] key. You must be certain that the quantity displayed matches the quantity on the scale before pressing the key. The unit weight can be adjusted based upon a larger sample quantity. This will give greater accuracy when counting larger sample sizes.

6.3.3 Check-counting

• Check-counting is a procedure to cause an alarm to sound when the

number of items counted on the scale meets or exceeds a number stored in the memory by using the [Pst] key.

• The value to be stored is entered from the keyboard. Enter the numeric

value to be stored using the numeric keys. Then press the [Pst] key to store the value.

• To clear the value from the memory and thereby turn off the check-

counting feature, enter the value "0" and press [Pst].

• During counting if the count is below the setpoint the “Lo” indicator will be on, if it is equal to the set point the “OK” indicator will be on and if it is above the limit the “Hi” indicator will be on.

P a g e 13 © Adam Equipment Company 2010

6.3.4 Manually Accumulated Totals

• The values (weight and count) shown on the display can be added to the values in the memory 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, the items have been added to the memory for accumulation. The values will be displayed for 2 seconds before returning to normal. If the accumulated number exceeds 6 digits the display will show “diSPEr”, the count is still being stored correctly and the RS232 printout will still show the correct values.

• The “Mem” symbol will be on when there are values stored in the accumulation memory.

• 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 to be pressed again. This can continue for up to 99 entries or until the capacity of the “Weight” display is exceeded. When the weight exceeds 6 digits the display will show “diSPEr”.

• To observe the total stored value, press the [MR] key. The total will be displayed for 2 seconds.

• To clear the memory- first press [MR] to recall the totals from memory and then press the [CE] key to clear all values from the memory.

6.3.6 Automatic Accumulated Totals

• The scale can be set to automatically accumulate totals 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 the Section 9.0 on RS-232 Interface for details on how to enable Automatic Accumulation.

• Press the [Zero] key to return to the menus. Press the [Zero] key again

to return to normal weighing.

12.2 USING “2006” TO ENTER THE SERVICE PARAMETERS

Before setting the parameters for units, decimal point, capacity and increment the user should make sure they understand how the scale should be configured. The scale is limited to 30,000 scale divisions. To determine the number of scale divisions divide the capacity by the desired increment. For example a 500kg scale reading to

0.01kg would have 50,000 divisions, a value not allowed. However a 500kg scale with interval of 0.02kg is 25,000 divisions, an acceptable number.

The order of the settings will request the default weighing unit first. This is to assign a weighing unit to the first calibration, regardless of what he user may select later. If the indicator has been configured for use in the USA the choice can be grams, kilograms or pounds. For the rest of the world it is kilograms or grams only. This setting should match the type of masses you have for calibration, imperial or metric.

The next 2 parameters will set the decimal point position, capacity and increment. It will be necessary for the settings to be within allowable limits for a setting to be accepted. For example, it is only allowed that the grams can be set to 45,000 or less. If you try to set the capacity to 50,000 grams it is not allowed, use kilograms for the default unit and set the capacity to 50kg. When setting the interval the options shown will only be those that allow the number of divisions to be 30,000 or less. For example setting capacity to 5000g and the decimal point to 0.0, the increment of 1 (=0.1g) is not allowed. Only the increment of 2, 5, 10 or 20 is allowed.
