Bar code input by means of a hand held wand or scanning gun.

Internal and/or external batteries for applications requiring operation without AC power.

1.3. STATEMENT OF PERFORMANCE

The performance of any count-by-weighing scale is dependent on uniformity of piece weight, the number of pieces in the sample, the weight of an individual piece and the per cent of rated load plac ed on the scale for a sample. Count accuracy is also dependant upon correct operation of the scale.

The 8572 high resolution parts counting scale significantly reduces count errors caused by the operator. In most applications, it provides better practical accuracy than either hand counting or other mechanical techniques. W ith the proper scale selection, c ount accuracy of ± one piece is attainable. However the most significant variable is non-uniformity in the weight of the parts to be counted; this variable is beyond the contr ol of the scale.

1.4. ACCURA CY CONSIDERATIONS

Counting accuracy is determined prim arily by two factors: Sample size as a percentage of full sc ale capacity and variation in weight from piece to piece of the parts to be counted.

The first factor is the most f requent cause of counting inac curacy because of the user's des ire to hand count the minimum possible num ber of sample pieces. Using too s mall a sample size results in limited accuracy. For example, with a sample weight equal to 0.05% of full scale c apacity, the internal sample weight resolution is ±1 part in 250, therefore counting acc uracy will be limited to ±0.4% in this example. Use of a sample size that is a higher percentage of full scale capacity will result in improved counting accuracy.

The overall count accuracy can be severely affected if the pieces used for the sample are not truly representative of the average piece weight. The sec ond factor is not under the control of the par ts counting scale, but this factor can be m inimized by using the largest practical sam ple size possible and resampling when counting different lots of the same material.

2. SYSTEM DESCRIPTION

The 8572 Logic PCB provides a DC voltage to the digital load cell which responds with numeric values proportional to the weight applied to the platter. This weight information is then used to determine the average piece weight and corresponding piece count. Setup parameters and calibration are ac ces sible via the fr ont k eyboard, so no internal access is required to configure the 8572. Setup and calibration data is stored in non-volatile m emory to prevent memory loss from occurring during a power outage.

2.1. INTERNAL FUNCTIONS

The basic 8572 consists of four major components. These are:

2.2. OPTIONAL KITS

The standard 0.6 A, 12 VDC power supply (*135156 00A), MUST be replaced with the optional 1.5 A, 12.5 VDC power supply (*135693 00A) when any optional KOP is installed in the Model 8572.

2.2.1. Bar Code

Scanning of bar code data can accomplished by means of the bar code wand kit or the bar c ode s canning gun kit. The 8572 can read Code 39, Interleaved 2 of 5, or Codabar form at bar code data. Tare, APW , and up to 16 digits of alphanumeric ID c an be scanned into the 8572. The 8572, when coupled with the Model 8860 thermal printer, can print up to six lines of bar code and/or human readable data on an adhesive label in a variety of formats.

2.2.2. Remote Scale Input

The 8572 remote scale input provides 1 part in 500,000 resolution and approx im ately nine weight updates per second. The 8572 can accommodate one remote scale base of either the DigiTOL® or analog type.

The remote DigiTOL® scale PCB is com patible with all Toledo Scale DigiT OL® scale bas es including the Model 2157 floor scale (digital j-box), also referred to as DigiTOL® POWER MODULE. The remote analog scale PCB can supply excitation voltage for up to four 350 ohm load cells and is com patible with both 2 mV/V and 3 mV/V analog load cells.

NOTE: The 8572 requires that four load cells be used with the digital j-box. The Model 2157 floor scale (digital j-box) provides up to 1 part in 280,000 resolution.

2.2.3. Battery Power Operation

2.2.3.1. Battery Powered Operating Time

The internal battery kit allows operation of the 8572 when AC power is not available. The internal battery provides up to 8 hours of power. The battery can be removed by means of an access cover located on the back of the 8572. T he normal rec harge time is approximately 12 hour s with the 8572 turned off. The exter nal battery pack provides up to 32 hours of power and is easily replaced with a freshly charged external battery pack for applications requiring extended use without AC power. T he normal battery recharge time is approximately 16 hours with the 8572 turned off.

Remote Analog Scale Base

(4-350 Α Load Cells)

To maximize the working life of a battery, recharge the battery on a the basis of how many hours the scale has been in use rather than running until the 8572 powers itself down. If a particular scale configuration results in a maximum battery charge life of 24 hours before the battery is exhausted, then the battery pack should normally be used for 8 hours and then recharged. Extra battery packs and an external battery charger are available to permit continuous battery powered operation. Following this procedure will greatly increase the service life of the battery and prevent premature battery failure.

a battery at temperatures above 860 F (300 C) shortens service life considerably.

Figure 2-1 Number of Recharge Cycles Related to Battery Discharge Depth

Always recharge batteries after use. Batteries stored in a discharged state may refuse to take a charge.

Storing batteries at 500 F (100 C) or below extends shelf life before recharging is necessary.

Batteries should be recharged every six months of s torage (when stored at room temperature) .

3.3. PHYSICAL SPECIFICATIONS

3.3.1. Appearance and Dimensions

The 8572 enclosure is fog white with a black platter ass em bly and multi-c olor k eyboard. the unit is 5.3" (135 mm) high, 14.7" (375 mm) wide and 14.6" (370 mm) deep. The standard 8572 weighs approximately 20 lb (9.1 kg). The bas e and sub-platter are made from die- cast aluminum . The 8572 uses a single point loading, moment-insensitive load cell. The cover and bezel are made of heavy structural plastic. A level indicator bubble is mounted in the sub-platter which can be viewed by removing the platter.

3.3.2. Internal Scale Platter

The 5 lb capacity scale has an 8" X 8" (205 m m) plastic platform . The 10, 25, 50, and 100 lb capacity scales has a 14.5" wide (370 mm) X 10.8" deep (275 mm) painted steel platter.

3.3.3. Shipping Information

Approximate shipping weight is 22 lb (10 k g). Carton dimensions ar e 9" (230 mm) X 19" (485 mm) X 19" (485 mm).

3.4. DATA INTERFACE

The 8572 supplies a bidirectional RS-232 printer port standard. The baud rate is selectable from 300 to 9600 baud and parity is selectable as even, odd, or parity bit always a "0". All data is in a 10 bit fram e: 1 start bit, 7 ASCII coded data bits, 1 parity bit and 1 stop bit. The 8572 printer port is powered by the external RS-232 device connected to the 8572. Both the transmit and receive RS-232 data lines of the 8572 printer port must be connec ted to a true RS- 232 exter nal devic e to permit data output. No hands hak e lines are provided on the printer port.

3.4.1. Data Output

When a print request oc curs (caus ed by pressing the an ASCII "P" into the printer port), the 8572 will output data unless output is inhibited. Data output will be inhibited by an unstable weight reading (scale "in motion"), an out of range weight reading (under zero or over capacity) or if the 8572 is in the expanded weight display mode. If repeat print is disabled the 8572 will output data only once per weighment after which the load on the scale must be removed and a new load placed on the scale before data can be output.

A selectable checksum character can be added to the data output to perm it detection of transmission errors. A selectable ASCII <SO> (shif t out) charac ter can be added to the data output to request lar ge print size in the Model 8806 and 8860 printers.

3.4.2. Data Input

The 8572 printer port can be configured to permit an external device to control the 8572. Upper case, ASCII characters ("C", "P","T" and "Z") received into the printer port are equivalent pressing to the

The platter is held by hook and loop fasteners in the corners. Remove the two #8-32 screws and rubber O rings from the top of the sub-platter. Remove the tape and shim from the top of the right side of the dead- deck . Locate the level bubble indicator located on the left front of the subplatter. Refer to Figure 4-1. Save all shipping hardware for future use.

4.1.2. Level the Scale Base

Figure 4-1 Low Capacity Shipping Hardware

Level the scale by turning the adjustable feet on the bottom of the scale bas e until the level indicator is correct. The feet mus t be adjusted so the scale does not roc k. Carefully tighten the lock nut at each adjustable foot. Refer to Figure 4-2.

Figure 2 - Level Bubble

4.1.3. Install All Optional KOPs

Install any desired options in the 8572. Refer to the installation instructions included with the optional kit of parts. Adding any option to the 8572 requires substituting the optional 1.5 A / 12.5 VDC power supply (*135693 00A) for the standard 0.6 A / 12 VDC power supply (*135156 00A).

4.1.4. Initial Power Up Sequence

Connect AC power to the 8572 and turn on the power switch (located on the right side of the base near the front). The following sequence of events will then occur:

All cursors, data fields, and legends light up and the decimal point then scr olls across the dis plays from the right-most digit to the left-most digit.

The software part number and revision level are then displayed for a few seconds. an example of the L02 revision powerup display. If a

[tESt ]

message is displayed instead of the

[135629 L02]

software part number then the 8572 is in the factory test mode. The test mode is entered by powering up the 8572 with the setup switch turned on and is for factory setup use only. To exit the test mode: power down the 8572, slide the setup switch to the rear of the enclosure, and power up the 8572. Refer to Section 4.2. for setup switch location and description.

During power up the Logic PCB tests all memory devices and establishes com munication with the load cell and any optional PCB's that are enabled in setup. Error m ess ages are displayed if any of the memory tests are failed or if the load cell or optional PCB does not respond.

[E3]

If an

error is displayed then the setup mem ory is corrupt. Access the setup as descr ibed in

Section 4.2. and verify 8572 programming and calibration. If any other error messages are displayed during the power up sequence refer to Sec tion 7.1. for

error code explanations and recommendations.

The last step of the power up sequence involves capturing zero on the gross scale if auto zero capture or tare interlocks are enabled in setup. If the weight on the gross scale is within the auto zero capture range (±2% or ±20% of programm ed scale capacity as selected in s etup), zero will be automatically captured by the 8572 and sample and gross scale selection will be as selected in setup step

If the weight reading is outside of the zero capture range, the prim ary display shows

[18]

[ E E E]

indicate that the weight indication is greater than the auto zero capture range. The primary display shows

[-E E E]

to indicate that the weight indication is less than the auto zero capture range.

4.2. PROGRAMMING PROCEDURE

The SETUP mode perm its access to the programm ing and calibration parameters. To enter the SETUP mode on the 8572, remove the platter ( on scales with the 11" by 14" platform) or rem ove the plastic cover

plug (on scales with the 8" square platter) and locate the setup s witch access hole. Refer to Figure 4-3. Slide the setup switch toward the front of the scale using a pointed, non-conductive object. Do not us e an object that could be easily dropped into the unit.

5.4. COUNTING OPERATION

The 8572 provides two modes of counting operation: Order dependent m ode with either sam pling or APW entry, and order independent mode.

ID, tare or APW values can be scanned in using the optional bar code input, inst ead of manually entering the data the 8572 is prompting for.

00.000

If ID is enabled, the operator is always prompted to enter an ID firs t. The 8572 accepts up to 16 digits of numeric ID from the keyboard or up to 16 alphanumeric characters from the optional bar code input.

5.4.1. Order Dependent Counting Modes

In the order dependent mode the 8572 prompts the operator step by step through the counting procedure, beginning with ID entry, then a tare entry, and finally a sampling procedure or APW entry. The order dependent mode is eas ier for an oper ator to learn than the order independent m ode and the step by step prompting by the 8572 helps ensure that required steps are not skipped.

The average piece weight that requires a new sample procedure be performed each time the parts are counted or when the average piece weight is not known.

The have consistent, known average piece weights. Another application that uses the APW entry mode involves the counting of very light parts that require an extremely large sample size to accurately calculate the APW . In this case the APW is calc ulated with a large sample size, this APW is recorded and used whenever this particular part is counted. Recorded APW values should be recalculated periodically with new parts to prevent counting errors that could occ ur if the parts average piece weight had changed since the last APW calculation.

5.5. SAMPLE ENHANCEMENT AND COUNTING WEIGHT RANGE PARAMETERS

The 8572 provides sample enhancement for single scale mode operation, to permit accurate counting of light weight or inconsistent parts without having to hand count a large sample size. When sample enhancement is used the APW is recalculated as more parts are placed on the scale. Sample enhancement requires at least one extra step in the normal count procedure.

To use sample enhanc ement, proceed through the normal count procedure until the 8572 is in the count mode, displaying the sample pieces. At this time, place additional pieces, roughly equivalent to but not more than the sample quantity already on the scale. The 8572 will then automatically recalculate the APW on the basis of the larger sample s ize. There is no need to count the extra sample piec es added during sample enhancement, j ust be sure to roughly double the number of piec es on the scale each tim e sam ple enhancement is used. Sample enhancement can be repeated as many times as needed (up to 4% of scale capacity), until the sample size required to accurately count a specific part is reached.

Four distinct zones of counting exist in relation to the weight on the platter. These zones are as follows:

Zone 1

: Below Minimum APW Computation Range

The weight placed on the sample sc ale is below the minimum APW c omputation (0.02% of f ull scale capacity). If sampling is attempted the primary display will show

[LO SPL]

and no sampling will occur.

Zone 2

: 0.02% of Scale Capacity to Minimum Sample Range

The weight placed on the sample scale is between 0.02% of full scale capacity and the minimum sample range selected in setup. If s ampling is attem pted the primar y display will show

[+ n]

where "n" is the maximum number of pieces that can be added to the sample scale on the basis of the APW calculated by the original sample. If m ore than this number of pieces is added to the s ample scale then

[/ / / / / / ]

will be displayed on the primary display until the correct number of pieces is plac ed on

the sample scale. A manual sample acceptance mode is also available which requir es the exac t number of samp le pieces

be added and the

[Sample]

(order independent mode) key be pressed. This results in the most

accurate APW calculation.

Zone 3

: Minimum Sample Range to 4% of Sample Scale Capacity, May Enhance Counting Zone

From the minim um sample range to 4% of sam ple scale capacity, the 8572 is operating in the count mode. Printing and accumulation can be performed as desired. The APW will be enhanced throughout this range unless too many pieces are added to the sam ple sc ale or weight is added to the gross scale. If the operator adds m ore pieces than can be reliably counted on the basis of the ear lier sample, the primary display will show

[/ / / / / / ]

for two seconds then return to showing count data.

If the operator wishes to continue APW enhancement, pieces must be r emoved from the scale until a change in sample weight no longer results in the

[/ / / / / / ]

display. APW enhancem ent will then

occur. If the operator ignores the

[/ / / / / / ]

display and adds more pieces, prints or accumulates, no further APW enhancement is possible for the current tr ansaction. Once the counting weight exceeds 4% of full scale capacity, APW enhancement is discontinued.

Note

: Zone 3 does not exist if average piece weight enhancement is disabled.

Zone 4

: Normal Counting Zone, 4% of Scale Capacity to Full Scale Capacity

Once the weight applied to the scale exceeds 4% of f ull scale capacity, APW enhancem ent is disabled and the displayed APW will no longer change.

6. INPUT AND OUTPUT CONNECTORS AND INTERFACING

6.1. PRINTER INTERFACE SPECIFICATIONS

The 8572 is capable of transmitting and receiving RS-232 voltage level ASCII characters. The device connected to the printer port must be a true RS-232 device. This is r equired because the voltage fr om the device's receive line is used to power the 8572's transmit line.

The 8572 transmits data suitable f or use with Toledo Scale printer Models 8806, 8842, and 8860. W hen the print function is actuated by means of the control command, the 8572 will output a mess age according to setup program ming. Scale m otion holds a printout until the scale sees "no motion". Printing is disabled when the scale is under gross zero, over capacity, or in expanded weight mode.

6.1.1. Data Format

The data output is in a 10 bit ASCII format: 1 start bit, 7 data bits, 1 parity bit (selectable to even, odd, or always a 0), and 1 stop bit. The baud rate can be set from 300, 1200, 2400, 4800, to 9600 baud.

Checksum is provided to ensure data integrity. Checksum is defined as the 2's complem ent of the 7 low order bits of the binary sum of all characters on a line, preceding the checksum.

The 8572 is capable of transmitting data in either a single line or multi line format. T he data fields to be printed are selected in setup. From one to seven f ields of data will be printed in the order deter mined in setup. Fields may be repeated as many times as desired.

Note

: If double width printing is enabled, an ASCII <SO> character, hex 0E, will precede the net weight or gross weight numeric field, (if printing displayed weight and the 8572 is in the gross mode). An ASCII <SI> character will follow the corresponding Units field.

Note

: If bracketed printing is enabled in setup then any truly measured weight will be preceded by a < character and followed by a > character.

Weight Field Format Notes:

The sign character is a space < > for positive net weights and a minus <-> for negative net weights. The weight data field is a seven character ASCII string consisting of six numeric digits plus a dec imal

Remove power from the scale by turning off the power switch located on the right side of the base near the front. Unplug the external power supply and external battery or internal battery if present.

Remove the platter, sub-platter, dead deck (lower capacity scales), and cover assemblies.

CAUTION!

On 8572-0002, 1002 versions that use the 3.75 kg load cell, reinstall the two #8-32 shipping screws through the sub-platter into the two hex standoffs. Refer to Figure 7-2. Do not tighten these screws down. They are used to keep the sub-platter from twisting when the sub-platter mounting screws are tightened or loosened. DAMAGE TO THE LOAD CELL MAY RESULT IF THIS PROCEDURE IS NOT FOLLOWED. Remove the two #8-32 screws, after the sub-platter mounting screws are tightened or loosened.

Figure 7-2 Low Capacity Shipping Hardware

Loosen the metal cover with the foil bellows that cover s the load cell. Do this by removing the four s crews that secure it to the base.

Disconnect the load cell harness from the load cell and set the cover assembly with the foil bellows aside. Remove the space block on top of the load cell and turn the scale on its side. Remove the two hex head screws from the bottom of the sc ale that secure the load c ell. The load c ell can

now be removed. Be sure to retrieve the spacer under the load cell. With the scale still on its side, reinsert the two hex head screws through the base and slide the bottom

spacer over the screws. Carefully install the new load cell by threading the screws into the bottom of the load cell. Tighten the

mounting screws to finger tightness. Stand the scale base upright and reinstall the top load cell spacer.

Reattach the load cell harness (that is attached to the metal cover with the foil bellows) to the load cell. Secure the metal cover to its original position above the load cell. T ighten the four screws that hold the

cover in place. Reinstall the cover and dead deck (on low capacity units).

Reattach the sub-platter. Refer to the caution at beginning of load cell replacem ent procedure for 85720002, 1002 units.

Check that the corner and center overload stops are aligned with the overload stop screws. Tighten all (4) load cell and sub-platter m ounting screws to 75 - 85 inch/pounds. Use a torque wrench to

ensure proper screw tension without over tightening. Place the platter on the sub-platter. Reconnect the internal battery or external battery if present and reconnect the external power supply.

Reapply power to the 8572 by means of the power switch located on the right side of the base near the front.

Verify operation and calibration of the new load cell as described in the calibration and operation section of the technical manual.

Note

: Overload stop clearance gaps must be checked after replacement of the load cell to provide proper

protection to the new load cell.

7.5. OVERLOAD STOP ADJUSTMENT

The overload stops mu st be adjusted when the load cell and/or sub-platter has been replaced. There c an be up to six overload stop positions, identified as X1 through X7. Factory numbers 8572-0002, and 1002, (5 lb capacity) versions use stops X1, X2, and X3. Overload s top X1 is located under the load cell. Refer to Figure 7-3 for overload stop locations. F actory numbers 8572-0003, - 0004, 0005, 0006, 1003, 1004, 1005, and 1006 (25 lb capacity and greater) scales use stops X2 through X7, refer to Figure 7-4.

Assemble the base, load cell, and sub-platter as described in the load cell replacement procedure in section

7.3. Mounting screws should be snug but not tight. Check that the corner and center over load stops are aligned with the overload adjus tment sc rews. Tighten

all (4) load cell and sub-platter mounting s crews to 75 - 85 inch/pounds. Use a torque wrench to ensure proper screw tension without over tightening.

Note

: All sub-platter and load cell mounting screws must be tightened to the proper specification before adjusting overload stops. Failure to do so m ay result in the overload stops being set incorre ctly and failure of the load cell.

7 CAUTION!

Never apply weight exceeding the capacity of the scale or shock load the scale if the overload stops have not been set.

7.5.1. Low Capacity Overload Adjustment (8572-0002, and 1002)

5 lb capacity overload stops are set by observing the expanded weight display as test weights are placed in specific locations on the scale platter.

With power applied, place the scale into the test m ode (setup step X1, X2, and X3.

[69 1]

) and loosen overload stops

The various test weights specified in T able 7-1 are placed in turn on the center of the platter to adj ust X1, the right rear corner to adjust X 2, and the right front corner to adjust X3. Ref er to Figure 7-3 and Table 7-1.

Tighten the overload screw for a given overload s top until the display weight just starts to change. T his indicates the overload screw is just touching the stop. Repeat this procedure for each of the three overload stops X1, X2, and X3.

10 lb and greater capacity scales overload stops are set by meas uring the gap between the overload stop and the overload screw. The gap is adjusted until it meets the s pecif ication listed in T able 7-2. All dimensions are listed in inches . Use round wire gauges, or the wire size equivalent drill bit to m easur e the overload stop gap.

DO NOT use flat feeler gauges to measure overload stop gap

- Tighten the overload screw until the gap is smaller than the wire gauge.

- Hold the wire gauge against the gap with a slight pressure.

- Slowly loosen the overload screw until the wire gauge snaps through the gap.

- Repeat this procedure for each of the six overloads X2, X3, X3, X4, X5, X6, and X7. Refer to
