INSTALLATION

Unpacking

Before beginning installation of your Digital Counting Scale, make certain the instrument has been received in good condition. Carefully remove the instrument from the shipping carton and inspect it for any evidence of damage (such as exterior dents or scratches) that may have taken place during shipment. Keep the carton and packing material for return shipment if it should become necessary. It is the responsibility of the purchaser to file all claims for any damages or loss incurred during transit. Refer to the Counting Scale Unpacking and Re-Packing

Instructions, 8526-M246-01, for additional information.

Placement

Place the scale on a stable, vibration-free level surface away from direct sunlight and from any rapidly moving air source (heating/cooling vents, fans, etc.). Make certain the power cord and peripheral cables are routed out of the way of normal traffic.

CAUTION! DO NOT place the scale on any unstable cart, stand or table. The scale may fall causing injury to the operator, and seriously damage the unit, or proper operation of the scale may be inhibited.

Level Adjustment

Check to make certain the scale is level. The level indicator is located in the center of the weighbridge under the Stainless Steel commodity tray. Remove the commodity tray and observe the level bubble (see Figure No. 1). If the scale is not level (the bubble will not be centered), loosen the locking nut on all four (4) mounting feet (see Figure No. 2) and adjust them as required to center the bubble and attain a level scale. Once a level condition has been obtained, lock the mounting feet in place by tightening the adjustment nuts against the bottom of the scale.

Figure No. 1

Power Connection

The scale contains a power supply which converts the 110/120/220/240 VAC 50/60Hz wall supply to the power required by the scale circuitry. The power supply also contains the circuitry necessary to monitor and recharge the optional battery and is capable of operating the scale and recharging the battery simultaneously.

PRECAUTIONS

Most scales are designed for an office type environment. The Digital Counting Scale is no exception to that rule. Such an environment is free of excessive dust and moisture and provides a comfortable temperature. In general, the scale will perform well over a temperature range of 32° to 104° F (0° to +40° C). In order to keep cooling requirements to a minimum, the scale should be placed out of direct sunlight and to provide adequate air circulation, keep the area around the scale clear. Make certain the scale is not directly in front of a heating or cooling vent. Such a location will subject the scale to sudden temperature changes and air currents which may result in unstable weight readings. Insure that the scale has good, clean AC power and is properly grounded. In areas subject to lightning strikes, additional protection to minimize lightning damage, such as surge suppressors, should be installed.

CAUTION! When in parallel runs, locate external Load Cell cables a minimum of 24 inches away from all AC wiring.

Page 7

INTERCONNECTIONS

Remote Scale Connection

If a remote scale is used, it connects to the counting scale via a 9-pin "D" connector (REMOTE SCALE) located on the rear panel of the scale (see Figure No. 2). Before connecting your remote scale to the counting scale, verify that your scale cable is correctly wired. Refer to Figure No. 3 for pin identification of the remote scale connector.

The Digital Counting Scale ships from the factory configured for remote scales that do not use load cells with sense leads (4 wire load cells). The sense jumpers, J1 and J2 are installed for proper operation with 4 wire load cells. If your remote scale uses load cells with sense leads (6 wire load cells), jumpers J1 and J2, located on the printed circuit board (see Figure No. 5) should be placed on one pin only or disconnected.

Make certain that the connector retaining screws are used to hold the remote scale cable connector securely to the rear panel.

This section describes the use of each of the keys on the Digital Counting Scale. It will be helpful to refer to the scale keyboard or Figure No. 6 when reading this section.

ZERO The ZERO key is used to perform a variety of functions depending on the current

mode of operation:

Weight Display Mode (lb or kg annunciator on): Pressing the ZERO key will set the weight display to zero and turn on the ZERO annunciator if the displayed weight is within ± 4% of scale capacity.

Count Mode (COUNT annunciator on): Pressing the ZERO key while in the Count mode will reset the count quantity to zero.

Accumulator Mode (ACCUM annunciator on): Pressing the ZERO key while in the Accum mode will reset the contents of the currently selected accumulator to zero.

PRINT Pressing the PRINT key will transmit RS-232 data to an optional printer,

recording time, date, weight, piece count and ID or part number. Refer to the Thermal Label Formats section of this manual and Figure No. 12 for typical print formats.

SAMPLE The SAMPLE key is used to weigh a known number of pieces to be added or

removed from the scale in preparation for a new counting operation. The SAMPLE key is also used to change the sample quantity. Pressing the SAMPLE key repeatedly will cause the sample size to step through pre-established sample sizes of 5, 10, 25, 50 and 100 pieces. In this manner sample quantities other than the first one requested by the scale can be used for counting operations. Sample quantities may also be entered using the numeric keypad in any quantity desired.

COUNT The COUNT key is pressed after removing or adding the requested sample, and

will place the scale in the COUNT mode and start the counting operation.

ACCUM Pressing the ACCUM key will cause the scale to display the contents of the

accumulator (the number of pieces accumulated since the last time the accumulator was zeroed) for the currently selected identification (ID) number.

+ (plus) The + (plus) key is used to add the current piece count value to the accumulator of

the currently selected identification (ID) number. The ACCUM annunciator will flash to indicate the accumulation has taken place.

- (minus) The - (minus) key is used to substract the current piece count value from the accumulator of the currently selected identification (ID) number. The ACCUM annunciator will flash to indicate the subtraction has taken place.

ID Pressing the ID key will cause the scale to display the currently selected

identification (ID) number and allow the entry of a new ID number.

LOCAL Pressing this key while displaying any weight information will select the SCALE instrument platform (LOCAL) for sampling, counting or weighing operations.

key will toggle between Net and Gross modes (illuminating the appropriate annunciator) with no change on the display.

TARE The TARE key is used to display the current tare weight (or zero if no tare has

been entered) and/or using the numeric keypad, to enter a new tare weight. It is also used when entering a tare under a specific indentification (ID) number.

TIME Pressing this key will allow the entry of hours-minutes-seconds (6 digits) followed DATE by the entry of the month-day-year (6 digits). NOTE: The time and date formats

are selected during setup of the counting scale.

lb/kg Pressing this key will toggle the weighing units between pounds (lb) and kilograms

(kg). NOTE: The currently selected weighing unit is indicated by illuminating either the lb or kg annunciator (LED).

REMOTE Pressing this key while displaying any weight will select the optional external SCALE scale (REMOTE) for sampling, counting or weighing operations. The Remote

Scale annunciator (LED) will illuminate to indicate the external (REMOTE) scale is in use. NOTE: The REMOTE scale cannot be selected until it has first been enabled in Setup and then calibrated.

ENTER The ENTER key is used to signal the completion of the data entry process and

starts the scale processing the data entered.

0 These keys are used to enter numeric data during setup and calibration as well through as during normal operations. NOTE: The 1 and 0 keys have dual functions. They 9 are used to enter numeric data during setup and calibration as well as during

normal operations and are also used to answer Yes (1=YES) or No (0 = NO) to various prompts.

This is the decimal point key used to enter a decimal point where required when entering numeric data.

CE The CE key is used to perform different functions depending on the current mode of

operation: Data Entry: The CE key is used to clear an incorrect entry from the display without

processing the data. If an incorrect entry is made, press the CE key and re-enter the correct data. NOTE: The CE key must be pressed before the ENTER key to ensure the data is not procesed.

Sample Mode (SAMPLE annunciator on): Pressing the CE key while in the Sample mode during the initial Add display will reset the Add value to 5. This display indicates the number of sample pieces to be added to (or removed from) the scale platform.

NOTE: An invalid key entry will produce a long tone and no change on the display.

Page 11

RESET FUNCTION

A hidden key (under the Cardinal bird emblem) is provided to be used as an reset function to abort the current operation and return the scale to the weight display mode. This allows the operator to start the operation again from the beginning.

Figure No. 6

ANNUNCIATORS

The annunciators are turned on to indicate that the scale is in the mode corresponding to the annunciator label or that the status indicated by the label is active. It will be helpful to refer to the scale keyboard or Figure No. 6 when reading this section. The following describes the functions of each annunciators.

GROSS

The GROSS annunciator is turned on to show that the weight displayed is the gross weight. Gross weight may be displayed only when in the weight mode and a zero tare weight (or no tare weight) value is stored. Note that the GROSS annunciator is only active when the display is in the weight mode as shown by the illumination of the lb or kg annunciator.

TARE

The TARE annunciator is turned on to show that the scale is in a weight mode in which a known tare (container) weight may be keyed in via the numeric keypad, or in a mode that will display the current TARE weight.

NET

The NET annunciator is turned on to show that the weight displayed is the net weight. Net weight is determined by subtracting the stored tare weight from the gross or scale weight. The tare weight, usually the weight of the container, is entered using the tare key. Note that the NET annunciator is only active when a zero tare weight or tare weight value is stored and the display is in the weight mode as shown by the illumination of the lb or kg annunciator.

The kg annunciator is turned on to show that the weight displayed is in kilograms. The lb/kg key may be used to select kilogram as the weighing units.

The lb annunciator is turned on to show that the weight displayed is in pounds. The lb/kg key may be used to select pounds as the weighing units.

ZERO

The ZERO annunciator is turned on to show that the scale gross weight is within ± ¼ of a division of true zero (center-of-zero).

Page 12

ANNUNCIATORS, Cont.

MOTION

The MOTION annunciator shows that the scale weight is unstable. An unstable weight reading may be caused by motion on the scale platform. Accumulation of piece counts, Zero and printing cannot take place when the MOTION annunciator is illuminated.

The ID annunciator is used to show the status of the Identification Number mode. During operation, the ID annunciator will be ON (not flashing) to indicate that an ID number is active. When the scale is in the ID ADD, EDIT or DELETE modes of operation, the ID annunciator will be flashing.

ACCUM

The ACCUM annunciator shows that the display is in the Accumulator mode and that the value displayed is the current contents of the accumulator. Individual counts are adjusted via the ( + ) and ( - ) keys or optionally, any count may be entered using the numeric keypad. Note, a flashing ACCUM annunciator indicates that the current count has been added to the accumulator (count annunciator is also lit).

SAMPLE

The SAMPLE annunciator shows that the display is in the Sample mode and that the value displayed is the sample quantity requested in pieces.

COUNT

The COUNT annunciator shows that the display is in the Count mode and the value displayed is the count quantity of either the pieces removed from the scale platform (reverse counting) or the number of pieces added to the scale platform (normal counting). The count value is determined by dividing the net or gross weight (as selected) by the average piece weight.

INSUFFICIENT SAMPLE

The INSUFFICIENT SAMPLE annunciator is located between the display and the numeric keypad and shows that the sample selected is too small to calculate an accurate piece weight. If a counting function is continued by pressing the COUNT key a second time without increasing the sample size, the INSUFFICIENT SAMPLE annunciator will flash. Note that increasing the sample size by the amount indicated prior to pressing the COUNT key a second time, will turn off the INSUFFICIENT SAMPLE annunciator and result in an accurate piece weight.

BATTERY LOW

The BATTERY LOW annunciator is used with the battery operation and will flash slowly to indicate that the internal battery requires charging. If continued use furthers drains the battery, the annunciator will stop flashing and stay on continuously. No change in operation will occur until just before the battery voltage drops to a level where operation is affected. At this level, the scale will automatically turn itself off. Note that when the scale is charging the battery, BATTERY LOW annunciator will flash until charging has been completed.

REMOTE SCALE

The REMOTE SCALE annunciator is illuminated when the optional remote scale platform has been selected for use. The remote scale is selected by pressing the REMOTE SCALE key.

POWER ON

The Power Switch is located on the right side panel towards the front of the scale. Place the power switch in the on position. The scale will perform a brief lamp test. This test consists of illuminating all display segments and annunciator LED's for approximately three (3) seconds to allow the operator to make a visual verification that the display is operational. After completion of the lamp test, the scale will display the model number and software revision level, then the weight display will show zero weight, indicating the scale is ready for use.

OPERATION USING ID(S)

This section describes the various operating procedures of the Digital Counting scale using the ID mode. The ID (identification number) function may be thought as a catalog of stored values for up to 300 separately identifiable counting operations. Those values, stored under an assigned ID number, are: the TARE WEIGHT1 (if used), the UNITS (Average Piece Weight) and the ACCUMULATED COUNT of a counting operation. They are accessed by entering the assigned ID number.

A TARE WEIGHT value can be stored for both the Local and Remote scale, allowing the

Operation With Stored Tare Weight Values

The Digital Counting Scale can store separate Tare weight values for each ID for both the Local and Remote scale. This allows the operator to use a smalll container for sampling and a larger container such as a pallet, tote or the shipping box for the final item count.

The TARE WEIGHT value can be programmed (stored) when first adding an ID or it can be added to the ID before or during a Count or Sample operation. Note, that if an ID has a stored Tare weight value and the Tare weight is updated during a Count or Sample operation, the updated value will become the stored Tare Weight value.

NOTE: When an ID is selected that has a stored Tare weight, the scale will automatically switch to the Net mode operation when the SAMPLE key or the COUNT key is pressed and display a negative weight (the Tare) if the container is not on the scale.

Automatic Average Piece Weight Re-Computation

Immediately after a standard sampling operation, if a quantity of pieces less than the original sample size is added to the scale platform, a new average piece weight will be calculated automatically. This new average piece weight is based on a larger sample than that used initially therefore improving the accuracy of the count.

NOTE: The automatic recomputation of the average piece weight occurs only once for each new sample. Note also that the recalculation of the average piece weight will not take place if the quantity of pieces added is equal to or greater than the original sample quantity, neither will it take place if the display mode is changed before the pieces are added.

If the weight of a sample is less than .1% or .5% of the gross capacity of the scale, (.1 lb or .5 lb for a 100 lb capacity scale) sample accuracy is not guaranteed. The Insufficient Sample annunciator will illuminate, and the scale will calculate the minimum additional number of pieces required to raise the sample weight to the .1% or .5% preset and display the quantity.

To change the setting, use the numeric keypad to key-in a new value (1 or 5, with no decimal) for the count accuracy, then press the ENTER key to save the setting and proceed to the next prompt.

AUTO SHUTOFF

The display will show a offa off, the prompt to enable or disable the Auto Shutoff feature and display the current setting. This feature, when enabled will automatically turn the scale off after a select period of inactivity to prolong battery life. To turn the instrument back on you must toggle the power switch from the ON position to the OFF position and then back to the ON position.

To change the setting, using the numeric keypad, key-in the number of minutes (1 through 9, time approximate) of inactivity before turning the scale off, then press the ENTER key to save the setting and proceed to the next prompt. Note, that entering a zero (0) disables the Automatic Shutoff feature.

DISPLAY INTENSITY

The display will show britebrite, the prompt to adjust the display intensity and display the current setting. This feature allows the display intensity (brightness) to be adjusted to compensate for lighting conditions at the scale's location. Also, when operating from the battery, lowering the display intensity decreases the load on the battery, increasing operating time before recharging is required. To change the setting, use the numeric keypad to key-in a new value (1 to 3) for the display intensity, then press the ENTER key to save the setting and proceed to the next prompt.

1 = DIM 2 = NORMAL (default setting) 3 = HIGH

CLEAR MEMORY

The display will show clr rclr r, the prompt to enable the Clear Memory operation and display the current (default) setting NO. This operation, when enabled will clear all ID's and associated accumulators from the scale memory. The Clear Memory operation is performed after turning the scale OFF and back ON with YES selected for the setup prompt. After clearing memory, the setup prompt will automatically return to NO, the default setting.

NOTE: The Clear Memory operation does not clear the Calibration or Setup information from the scale. The Calibration and Setup data are stored in non-volatile memory (NOVRAM) and can only be changed using their respective procedures.

To enable the Clear Memory operation, press the YES/1 key, then press the ENTER key to save the setting and proceed to the next prompt.

SAMPLING AND COUNT ACCURACY

This section describes certain conditions that determine the accuracy of a parts counting operation and procedures you can follow to assure optimum performance of your Digital Counting Scale. Accurate counts depend upon the following conditions:

Functional accuracy of the scale. Individual part weight variance. Determination of parts sampling quantities. Variance of container weights in tare operations.

ACCURACY OF THE SCALE (Refer to Figure No. 9) TYPICAL CONDITION ACCURACY - on a stable surface, applied load less than 70% of scale

capacity, with no air currents or vibrations present, using parts with weight variance less than 1%; the total weight of all parts in the sample must be:

0.2% (1/500) of scale capacity for 99.5% accuracy

0.1% (1/1000) of scale capacity for 99% accuracy.

WORST CASE ACCURACY - on an unstable surface, applied load near 100% of scale capacity, with air currents or vibrations present, using parts with weight variance less than 1%; the total weight of all parts in the sample must be:

0.5% (1/200) of scale capacity for 99.5% accuracy

Counting accuracy will be greater than 99.5% when the total weight of all parts in the sample exceeds 0.5% of scale capacity.

SAMPLING AND COUNT ACCURACY, Cont.

INDIVIDUAL PART WEIGHT VARIANCE

For a given sample quantity, as the total weight of all parts in the sample increases, the average per-piece weight of the sample used becomes representative of the average per-piece weight of the group of parts to be counted. The errors caused by part weight variance are reduced with larger sample quantities. With knowledge of the typical percentage of variartion in per-part weight of items to be counted, refer to the graph in Figure No. 10 to determine the sample quantity needed to obtain a desired percentage of counting accuracy.

As your need for counting accuracy increases, the size of your samples must also increase. As individual uniformity of your parts decreases, sample size must increase. Manual counting errors may occur if samples larger than necessary are used. Because of variation of individual container weights, be certain to "tare off" each container by placing the empty container on the scale and pressing the ZERO key before proceeding with the count operation.

1. Select the typical % of variation in the sample part-weight on the left-hand side of the graph.

2. Follow the selected curve to the right and upward to the % of sample accuracy.

3. Read down vertically from the % of accuracy to the corresponding minimum quantity of parts required for sampling to obtain the desired minimum % of count accuracy.

OPTIONAL BATTERY PACK OPERATION

The Digital Counting Scale can operate from a readily available Sealed Lead-Acid Camcorder type battery (not included). If you wish to operate the scale from a battery, you must first obtain and install a CAM-350 Type 12 volt 2000 mAh (2.0 Ah) battery before operations can begin. The battery is contained inside the instrument and is easy to install. Access is via a removable panel on the right side of the scale (See Figure No. 11). The scale will operate with a "fully charged" battery for approximately ten (10) hours and is easily recharged with the scale's built-in charger.

NOTE: The battery can be purchased from the Cardinal Scale Parts Department (p/n 6800-0018) or ordered from the following companies online:

OPTIONAL BATTERY PACK OPERATION, Cont.

Discharging the Battery Pack

The battery pack is discharging when the scale is operated without the AC power cord plugged into a wall outlet. The Battery Low annunciator on the scale keypad serves to indcate the state of the battery pack.

When the scale is operating by battery power, and the battery pack has sufficient charge to power the scale, the Battery Low annunciator is off. If the battery becomes discharged while the scale is in use, the Battery Low annunciator will flash slowly to indicate the battery pack needs to be charged. When this occurs, the battery pack will have sufficient charge to power the scale for a short time, approximately (5) five minutes. If continued use further drains the battery pack, the Battery Low annunciator will stop flashing and stay on until the battery pack becomes severely discharged. When the battery pack is unable to power the scale, the scale will turn off automatically to prevent damaging the battery.

Due to the nature of batteries, shutting the scale off will cause the battery pack to recover slightly. If the scale is operated after turning itself off, it may run for a few minutes before the Battery Low annunciator begins to flash again. If the battery pack is too discharged to power the scale, it will not power up when the power switch is place in the ON position, but will illuminate the Battery Low annunciator for one minute to show the operator that a charge is needed before operations can continue.

If the battery pack has become severely discharged, the scale may not respond at all when turned on. This is a safety feature to prevent the scale from being powered up when the battery voltage is excessively low. Plug the scale into the AC wall outlet to charge the battery pack.

Charging the Battery Pack

The battery pack can be recharged with the built-in charger in the scale. The charger in the scale is a dual-level float charger. The first level does most of the charging rapidly, while the second level adds the remaining charge gradually. This type of charge profile greatly prolongs the life of the battery pack. Due to the sophisticated nature of the charger the battery pack can be left connected to the charge indefintely, without risk of damage.

When the battery pack installed in a scale needs to be charged, simply plug the AC power cord into a wall outlet and charging will begin. Note that operating the scale during charging only minimally affects the charge time of the battery pack. The scale can operate at a 100% duty cycle and will only prolong the charge time by less than 20%. Note too that charge time is dependent on the depth of the discharge and will vary from one application to the next, but will typically not exceed 10 hours even with the scale turned on.

While the battery pack is charging, the Battery Low annunciator will flash. It will continue to flash until the battery is fully charged. Upon reaching full charge, the annunciator will turn off. This gives the operator a visible indication of the charging status of the battery. Note that the Battery Low annunciator is only on when the scale is on. If the battery pack is charged with the scale off, the scale must be turned on to determine status of the battery.

OPTIONAL BATTERY PACK OPERATION, Cont.

Optimum Battery Pack Performance

The life of the battery pack depends greatly on the duty cycle of the scale, depth of discharge and operating temperature. The battery pack will normally provide eight (8) hours of continuous operation over an operating range of 14° to 104° F (-10° to +40° C). Several steps can be taken to optimize the performance and life of the battery pack.

1. Enable the Auto Shut-Off feature of the scale by entering a 1 (YES) when the scale prompts for Auto Off during Setup. (Refer to the Setup and Calibration section for an explanation of the setup feature). This selection will cause the scale to shut itself off after the period of inactivity selected in setup, thus preserving the battery pack.

2. If possible, plug the AC power cord into a wall outlet after each work shift to allow the battery pack to recharge. This will minimize the depth of discharge and greatly increase the number of cycles the battery pack can undergo.

3. If conditions permit, avoid charging and discharging the battery pack in extreme cold. Due to the chemistry of batteries, low temperatures decrease the capacity of the battery pack significantly causing a greater depth of discharge at colder temperatures than at room temperature. The battery pack will function without problems at temperatures as low as 14° F (-10° C) but will not last as many cycles as it would at room temperature.

4. Avoid storing the battery pack after discharging. If the battery pack is to be left for several days or more, make certain that it is charged before storage. The optimum environment for batteries is to charge while stored. The type of charger used in the scale will not damage batteries in any way even if the battery pack is left charging indefinitely.
