About This Manual

This manual is intended for use by service techniciansresponsible for installing and servicing 120

digitalweight indicators. This manual applies to indicatorsusing Version 1.0 of the 120

software.

Conguration and calibration of the indicator can beaccomplished using the indicator front panel keys, theEDP command set, or Version 3.0 or later of theRevolution

conguration utility. See Section 3.1 onpage 7for information about conguration methods.

Some procedures described in this

manual require work inside the

indicator enclosure. These proc edures

are to be perfo rmed by qualified

service personnel only.

Authorized distributors and their employeescan view or download this manual from theRice Lake Weighing Systems distributorsite at www.rlws.com

.

The Operator Card

included with this manualprovides basic operating instructions for users of the

120

. Please leave the Operator Card

with the indicatorwhen installation and conguration are complete.

1.0 Introduction

The 120

is a single-channel digital weight indicator housed in a durable plastic enclosure. The indicator frontpanel consists of a large (.8 in, 20 mm), six-digit, seven-segment LED display and ve-button keypad. Featuresinclude:

Drives up to four 350

W or eight 700

W

load cells Supports 4- and 6-wire load cell connections Electronic data processing (EDP) port for full duplex, RS-232 communications at up to 38400 bps Printer port for output-only RS-232 and 20 mA current loop communications at up to 9600 bps

The 120

is NTEP-certied for Classes III and III L at 6,000 divisions. See Section 7.8 on page 36for detailedspecications.

1.1 Operating Modes

The 120

supports the following modes of operation:

Normal (weighing) mode

Normal mode is the production mode of the indicator. The indicator displays gross or net weights asrequired, using the LED annunciators described in Section 1.3 on page 2to indicate scale status and the typeof weight value displayed. Once conguration is complete and a legal seal is afxed to the back of theindicator, this is the only mode in which the 120

can operate. See Section 1.4.1 on page 3 for moreinformation about normal mode operations.

Pa nel mode

Panel mode allows the time, date, consecutive number, and consecutive number start-up value to be setwithout entering conguration mode. To enter panel mode, press and hold the GROSS/NET

key until the

TIME

menu is shown. See Section 1.4.2 on page 4for more information about panel mode.

Configuration mode

Most of the procedures described in this manual require the indicator to be in conguration mode, includingconguration and calibration.To enter conguration mode, remove the large llister head screw from the enclosure backplate. Insert ascrewdriver or a similar tool into the access hole and press the setup switch once. The indicator displaychanges to show the word CONFIG

.

Test mode

Test mode provides a number of diagnostic functions for the 120

indicator. Like setup mode, test mode isentered using the setup switch. See Section 7.7 on page 35for more information about entering and usingtest mode.

1.2 Front Panel Keypad

Figure 1-1shows the 120

keypad and LED annunciators.

The symbols shown under the keys (representing up, down, enter, left, right) describe the key functions assignedin conguration and panel modes. In these modes, the keys are used to navigate through menus, select digitswithin numeric values, and increment/decrement values. See Section 3.1.3 on page 8for information about usingthe front panel keys in conguration mode.

Figure 1-1. 120

Front Panel

1.3 LED Annunciators

The 120

display uses a set of eight LED annunciators to provide additional information about the value beingdisplayed:

Gr

(gross) and Nt

(net) annunciators are lit to show whether the displayed weight is a gross or net weight. Center of zero ( ): Gross weight is within 0.25 graduations of zero. This annunciator lights when the

scale is zeroed.

Standstill ( ): Scale is at standstill or within the specied motion band. Some operations, includingtare functions and printing, can only be done when the standstill symbol is shown.

lb, kg, oz, and

g annunciators indicate the units associated with the displayed value: lb=pounds,kg=kilograms, oz=ounces, g=grams.The displayed units can also be set to short tons (tn), metric tons (t), or NONE (no units informationdisplayed). The lb

and kg

LEDs function as primary and secondary units annunciators for somecombinations of primary and secondary units. If neither primary nor secondary units are lb, kg, oz, or g, the

lb

annunciator is lit for primary units, kg

for secondary units.Table 1-1 on page 3shows which annunciators are used for all combinations of congured primary andsecondary units. For example:

If the primary unit is pounds (lb) and the secondary unit is kilograms (kg), the lb

LED is lit for primaryunits, kg

for secondary units. If the primary unit is pounds (lb) and the secondary unit is short tons (tn), the lb

LED is lit for primaryunits, kg

for secondary units. There is no LED for short tons, so the kg

LED is used as the secondaryunits annunciator.

If the primary unit is short tons (tn) and the secondary unit is pounds (lb), the lb

LED is lit for primaryunits (tn), and kg

is lit for secondary units (lb). Because there is no LED for short tons, the lb

and kg

LEDs are used as primary and secondary units annunciators.

R e v o l u t i o n I I I supports both uploading anddownloading of indicator conguration data. Thiscapability allows conguration data to be retrievedfrom one indicator, edited, then downloaded toanother.

To use Revolution III, do the following:

1. Install Revolution III(Version 3.1 or later) on anIBM-compatible personal computer runningWindows 98 or later. Minimum systemrequirements include a processor speed of atleast 166MHz, 32MB of memory (64MBrecommended, required for NT4, 2000, XP),and at least 40MB of available hard disk spacefor installation.

2. With both indicator and PC powered off,connect the PC serial port to the RS-232 pins on

the indicator EDP port.3. Power up the PC and the indicator. Use the setup

switch to place the indicator in setup mode.4. Start the Revolution IIIprogram.

Figure 3-1 shows an example of one of the Revolutionconguration displays.

Revolution IIIprovides online help for each of i tsconguration displays. Parameter descriptionsprovided in this manual for front panel congurationcan also be used when conguring the indicator usingRevolution: the interface is different, but theparameters set are the same.

3.1.2 EDP Command Configuration

The EDP command set can be used to congure the 120indicator using a personal computer, terminal, or remotekeyboard. Like Revolution, EDP command conguration sends commands to the indicator EDP port; unlikeRevolution, EDP commands can be sent using any external device capable of sending ASCII characters over aserial connection.

EDP commands duplicate the functions available using the indicator front panel and provide some functions not

otherwise available. EDP commands can be used to simulate pressing front panel keys, to congure the indicator,or to dump lists of parameter settings. See Section 5.0 on page 23for more information about using the EDPcommand set.

3.1.3 Front Panel Configuration

The 120indicator can be congured using a series of menus accessed through the indicator front panel when theindicator is in setup mode. Table 3-1summarizes the functions of each of the main menus.

Four front panel keys are used as directional keys to navigate through the menus in setup mode. The UNITS( )and PRINT ( ) keys scroll left and right (horizontally) on the same menu level; ZERO( ) and GROSS/NET( )move up and down (vertically) to different menu levels. The TAREkey ( ) serves as an Enter key for selectingparameter values within the menus. A label under each of these keys identies the direction provided by the keywhen navigating through the setup menus.

To select a parameter, press or to scroll left or right until the desired menu group appears on the display,then press to move down to the submenu or parameter you want. When moving through the menu parameters,the default or previously selected value appears rst on the display.

To change a parameter value, scroll left or right to view the values for that parameter. When the desired valueappears on the display, press to select the value and move back up one level.

NOTE:You must press to save the selected value. The 120d oes not automatically save the last-displayed value.

To edit numerical values, press (rightmost digit willash), then use the navigation keys to select the digit

and to increment or decrement the value (seeFigure 3.2). When done, press again to save theedited value.

Calibration 21

4.0 Calibration

The 120can be calibrated using the front panel, EDP commands, or the Revolutionconguration utility. Eachmethod consists of the following steps:

Zero calibration

Entering the test weight value Span calibration Optional rezero calibration for test weights using hooks or chains.

The following sections describe the calibration procedure for each of the calibration methods.

Figure 4-1. Calibration (CALIBR) Menu

4.1 Front Panel CalibrationTo calibrate the indicator using the front panel, do thefollowing:

1. Place the indicator in conguration mode(display reads CONFIG) and remove all weightfrom the scale platform. If your test weights

require hooks or chains, place the hooks orchains on the scale for zero calibration.2. Press until the display reads CALIBR (see

Figure 4-1). Press to go to zero calibration(WZERO).

3. With WZERO displayed, press to calibratezero. The indicator displays *CAL*whilecalibration is in progress. When complete, theA/D count for the zero calibration is displayed.DO NOT adjust this value after WSPAN hasbeen set! Press again to save the zerocalibration value and go to the next prompt(WVAL).

4. With WVALdisplayed, place test weights on thescale and press to show the test weight value.Use the procedure shown in Figure 4-2to enterthe actual test weight, then press to save thevalue and go to span calibration (WSPAN).

5. With WSPAN displayed, press to calibratespan. The indicator displays *CAL*whilecalibration is in progress. When complete, theA/D count for the span calibration is displayed.Press again to save the span calibration valueand go to the next prompt (REZERO).

6. The rezero function is used to remove acalibration offset when hooks or chains are usedto hang the test weights. If no other apparatus was used to hang the test

weights during calibration, remove the test

weights and press to return to the CALIBRmenu. If hooks or chains were used during

calibration, remove these and the test weightsfrom the scale. With all weight removed,press to rezero the scale. This functionadjusts the zero and span calibration values.The indicator displays *CAL*while the zeroand span calibrations are adjusted. Whencomplete, the adjusted A/D count for the zerocalibration is displayed. Press to save thevalue, then press to return to the CALIBRmenu.

7. Press until the display reads CONFIG, thenpress then to exit conguration mode.

4.2 EDP Command CalibrationTo calibrate the indicator using EDP commands, theindicator EDP port must be connected to a terminal orpersonal computer. See Section 2.2.1 on page 6forEDP port pin assignments; see Section 5.0 on page 23for more information about using EDP commands.

Once the indicator is connected to the sending device,do the following:

1. Place the indicator in conguration mode(display reads CONFIG) and remove all weightfrom the scale platform. If your test weightsrequire hooks or chains, place the hooks orchains on the scale for zero calibration.

2. Send the WZERO EDP command to calibratezero. The indicator displays *CAL*whilecalibration is in progress.NOTE: During EDP command calibration, the

*CAL*message rem ains on the disp lay. The OK

response is returned w hen calibration is comp lete.

3. Place test weights on the scale and use theWVAL command to enter the test weight valuein the following format:

WVAL= nnnnnn

4. Send the WSPAN EDP command to calibratespan. The indicator displays *CAL*whilecalibration is in progress.

5. To remove an offset value, clear all weight fromthe scale, including hooks or chains used to hangtest weights, then send the REZERO EDPcommand. The indicator displays *CAL*whilethe zero and span calibrations are adjusted.

6. Send the KUPARROW EDP command to exitconguration mode.

EDP Commands 23

5.0 EDP Comma nds

The 120indicator can be controlled by a personalcomputer or remote keyboard connected to theindicator EDP port. Control is provided by a set ofEDP commands that can simulate front panel key

press functions, display and change setup parameters,and perform reporting functions. The EDP portprovides the capability to print conguration data or tosave that data to an attached personal computer. Thissection describes the EDP command set andprocedures for saving and transferring data using theEDP port.

5.1 The EDP Command SetThe EDP command set includes key press commands,mode commands, reporting commands, the RS specialfunction command, and parameter setting commands.

The indicator responds to most EDP commands bysending the message OK. The OKresponse veriesthat the command was received and has beenexecuted. (Pressing ENTERafter processing a validEDP command repeats the previous command.) If thecommand is unrecognized or cannot be executed, theindicator responds with ??.

The following sections list the commands andcommand syntax used for each of these groups.

5.1.1 Key Press Commands

Key press EDP commands (see Table 5-1) simulatepressing the front panel indicat or keys. These

commands can be used in both conguration andweighing mode.

5.1.2 Mode Commands

The Mode EDP commands (Table 5-2) can be used tos w i tch th e ac t iv e mo d e o f th e in d ica to r toconguration or test mode.

5.1.3 Reporting Commands

Reporting commands (Table 5- 3) send specicinformation to the EDP port. These commands can beused in both conguration mode and normal mode.

5.1.4 The RS Command

The RS (reset conguration) command can be used torestore all conguration parameters to their defaultvalues. Before issuing this command, the indicatormust be placed in test mode (press and hold setupswitch for approximately three seconds to enter testmode).

This command is equivalent to using the DEFLTfunction on the TEST menu. See Section 7.7 onpage 35for more information about test mode andusing the TEST menu. NOTE:All load cell calibrationsettings are lost when the RS command is run.

5.1.5 Parameter Setting Commands

Parameter setting commands allow you to display or

change the current value for a particular congurationparameter (Tables 5-4through 5-9).

Current conguration parameter settings can bedisplayed in either conguration mode or normalmode using the following syntax:

command

Mo s t p a rame te r v a lu es can b e ch an g ed inconguration mode only. Use the following commandsyntax when changing parameter values:

command= value

5.2 Saving and Transferring DataConnecting a personal computer to the 120EDP port allows you to save indicator conguration data to the PC orto download conguration data from the PC to an indicator. The following sections describe the procedures forthese save and transfer operations.

5.2.1 Saving Indicator Data to a Personal Computer

Conguration data can be saved to a personal computer connected to the EDP port. The PC must be running acommunications program such as PROCOMMPLUS. See Section 2.2.1 on page 6for information about serialcommunications wiring and EDP port pin assignments.

When conguring the indicator, ensure that the values set for the BAUD and BITS parameters on the SERIALmenu match the baud rate, bits, and parity settings congured for the serial port on the PC. Set the PRNDESparameter to EDP.

To save all conguration data, place the indicator in conguration mode and send the DUMPALL EDP commandto the indicator. The 120responds by sending all conguration parameters to the PC as ASCII-formatted text.

5.2.2 Downloading Configuration Data from PC to Indicator

Conguration data saved on a PC or oppy disk can be downloaded from the PC to an indicator. This procedureis useful when a number of indicators with similar congurations are set up or when an indicator is replaced.

To download conguration data, connect the PC to the EDP port as described in Section 5.2.1. Place the indicatorin conguration mode and use the PC communications software to send the saved conguration data to theindicator. When transfer is complete, calibrate the indicator as described in Section 4.0 on page 21.

NOTES:

Calibration settings are included in the conguration data downloaded to the indicator. If the receivingindicator is a direct replacement for another 120and the attached scale is not changed, recalibration isnot required.

When downloading congurations that include changed serial communications settings, edit the data leto place the serial communications changes at the end of the le. Communication between the PC andindicator will be lost once the indicator receives settings for baud rate (BAUD parameter) or data bits andparity (BITS parameter) that do not match those congured for the PC.

Print Formatting 27

6.0 Print Formatting

The 120print format can be edited to specify theformat of the printed output when the PRINTkey ispressed or when a KPRINT EDP command isreceived.

Each print format can be customized to include up to300 characters of information, such as company nameand address, on printed tickets. You can use theindicator front panel (PFORMT menu), EDPcommands, or the Revolution conguration utility tocustomize the print format.

6.1 Print Formatting CommandsTable 6-1lists commands you can use to format theprint format. Text included in the format string mustbe enclosed in quotation marks (hex 22). Textcharacters can include any ASCII character that can be

printed by the output device.

The default 120print format is shown below:@ G < C R> @ M @ T @ N @ M < C R >

NOTE: The 300-character limit of the print formatstring includes the output eld length of the printformatting commands, not the command length. Forexample, if the indicator is congured to show a

decimal point, the @G command generates an outputeld of 13 characters: the 10-character weight value(including decimal point), one space, and a two-digitunits identier.

6.2 Customizing Print FormatsThe following sections describe procedures forcustomizing the print format using the EDP port or thefront panel (PFORMT menu).

6.2.1 Using the EDP Port

With a personal computer, terminal, or remotekeyboard attached to the 120EDP port, you can usethe EDP command set to customize the print formatstring.

To view the current setting of the print format, typeWWPF (to enter ASCII text) or WPF (to enter hexvalues) then press ENTER. The indicator responds bysending the current conguration for the print format:

Use the WWPF or WPF EDP command followed byan equals sign (=) and zero (0) to edit the print formatstring.

The following example shows the commands used todene a print format string for an Eltron LP-2742

printer.NOTE:The N, AxxxxxxN, Bx, and P1 comm ands used in

the example are all Eltron p rinter-specific commands.

6.2.2 Using the Front Panel

If you have no access to equipment for communication through the EDP port or are working at a site where suchequipment cannot be used, you can use the PFORMT menu (see Figure 6-1) to customize the print format. Usingthe PFORMT menu, you can edit the print format string by changing the hex values of the ASCII characters inthe format string.

To edit a print format, do the following:

1. In setup mode, use the navigation keys to go to the PFORMT menu. Press to show the EDIT submenu.2. Press again to show the print format string. Use the and keys to scroll through the format. The

number position of each character is shown in the two digits at the left of the display, hex 00BF.3. To edita character, press while the character is displayed. The rightmost digit ashes, indicating that

it can be changed. Use the and keys to increment or decrement the value, or use the key to moveto the next digit. Press to save any changes and advance to the next character in the string.

4. If done, press to return to the EDIT submenu.5. To insertone or more characters, display the character position afterwhich characters are to be inserted.

Press to return to the EDIT submenu, then press to show the INSERT parameter. Press to insertone character; repeat presses to add more characters. Each press of the key adds a character at thelocation last shown under EDIT submenu and shifts all subsequent characters to the right. Insertedcharacters are assigned hex value 00 (null).

To edit inserted characters, return to the EDIT submenu and make changes as described under step 3.6. To deleteone or more characters, display the character to be deleted. Press to return to the EDIT

submenu, then press twice to show the DELETE parameter. Press to delete one character; repeatpresses to delete more characters. Each press of the key deletes a character, starting at the location lastshown under EDIT submenu, then moving left to preceding characters. Each deletion shifts allsubsequent characters to the left.

NOTE:Some characters cannot be displayed on the 120front panel (see the ASCII character chart on page 31)and are shown as blanks. The 120can send or receive any ASCII character; the character printed depends on theparticular ASCII character set implemented for the receiving device.

7.5 Conversion Fac tors for Secondary UnitsThe 120has the capability to mathematically convert aweight into many different types of units and instantlydisplay those results with a press of the UNITSkey.

Secondary units can be specied on the FORMATmenu using the SECNDR parameter, or by using EDPcommands.

To congure secondary units using the frontpanel menus, use the Table 7-4to nd theconversion multiplier for the MULT parameter.For example, if the primary unit is pounds andthe secondary unit is short tons, set the MULTparameter to 000050.Next, use the MULEXP parameter to set thedecimal point position. In the example above,the conversion factor for pounds to short tons isactually 0.0005 (2000 lb x 0.0005 = 1 tn). Usethe and keys to shift the decimal point toshow a value of 0.00050.Another example: If the primary unit is ouncesand the secondary unit is grams, the conversionfactor is 28.3495. To enter this value using themenus, rst enter 283495 for the MULTparameter, then use the MULEXP parameter toadjust the decimal point to 28.3495.

To congure secondary units using EDPcommands, use the Table 7-4 to nd theconversion value for the SEC.MULT andcommand. For example, if the primary unit ispounds and the secondary unit is short tons, sendthe following EDP command to set themultiplier for the secondary units.

SEC.M ULT= 0.00050

Units of weight other than those listed inTable 7-4cannot be directly specied as primaryor secondary units on the 120indicator. Forunlisted units of weight, specify NONE on theUNITS parameter.

NOTE:Ensure that the secondary decimal pointposition is set appropriately for the scale capacity inthe secondary units. If the converted value requiresmore digits than are available, the indicator displaywill overow.

For example, if the primary units are short tons,

secondary units are pounds, and the secondarydecimal point is set to 8888.88, the indicator willoverow if 5 tons or more are applied to the scale.With 5 tons applied, and a conversion factor of 2000,the secondary units display needs ve digits to the leftof the decimal point to display the 10000 lb secondaryunits value.

7.6 Digital FilteringThe 120uses averaged digital ltering to reduce theeffect of vibration on weight readings. Adjustablethreshold and sensitivity functions allow quicksettling by suspending lter averaging, allowing theweight reading to jump to the new value. Digital

ltering parameters are set using the CONFIG menu.7.6.1 DIGFLxParameters

The rst three digital ltering parameters, DIGFL1,DIGFL2, and DIGFL3, are congurable lter stagesthat control the effect of a single A/D reading on thedisplayed weight. The value assigned to eachparameter sets the number of readings received fromthe preceding lter stage before averaging.

The overall ltering effect can be expressed by addingthe values assigned to the three lter stages:

DIGFL1 + DIGFL2 + DIGFL3

For example, if the lters are congured asDIGFL1=4, DIGFL2=8, DIGFL3=8, the overall l te r ing e f fec t i s 20 (4 + 8 + 8 ) . With th isconguration, each A/D reading has a 1-in-20 effecton the displayed weight value. Setting the lters to 1effectively disables digital ltering.

7.6.2 DFSENS a nd DFTHRH Pa rameters

The three digital lters can be used by themselves toeliminate vibration effects, but heavy ltering alsoincreases settling time. The DFSENS (digital ltersensitivity) and DFTHRH (digital lter threshold)parameters can be used to temporarily override lter

averaging and improve settling time: DFSENS species the number of consecutivescale readings that must fall outside the lterthreshold (DFTHRH) before digital lteringis suspended.

DFTHRH sets a threshold value, in displaydivisions. When a specied number ofconsecutive scale readings (DFSENS) falloutside of this threshold, digital ltering issuspended. Set DFTHRH to NONE to turn offthe lter override.

7.6.3 Setting the Digital Filter Parameters

Fine-tuning the digital lter parameters greatlyimproves indicator performance in heavy-vibrationenvironments. Use the following procedure todetermine vibration effects on the scale and optimizethe digital ltering conguration.

1. In setup mode, set all three digital lters(DIGFL1, DIGFL2, DIGFL3) to 1. SetDFTHRH to NONE. Return indicator tonormal mode.

2. Remove all weight from the scale, then watchthe indicator display to determine themagnitude of vibration effects on the scale.Record the weight below which all but a fewreadings fall. This value is used to calculatethe DFTHRH parameter value in Step 4.For example, if a heavy-capacity scaleproduces vibration-related readings of up to50 lb, with occasional spikes to 75 lb, record

50 lb as the threshold weight value.3. Place the indicator in setup mode and set thedigital lters (DIGFLx) to eliminate thevibration effects on the scale . (LeaveDFTHRH set to NONE.) Recongure asnecessary to nd the lowest effective valuesfor the DIGFLxparameters.

4. With optimum values assigned to the DIGFLxparameters, calculate the DFTHRH parametervalue by converting the weight value recordedin Step 2 to display divisions:threshold_weight_value / DSPDIV

In the example in Step 2, with a thresholdweight value of 50 lb and a display divisionvalue of 5lb: 50 / 5lb = 10DD. DFTHRHshould be set to 10DD for this example.

5. Finally, set the DFSENS parameter highenough to ignore transient peaks. Longertransients (typically caused by lower vibrationfrequencies) will cause more consecutiveout-of-band readings, so DFSENS should beset higher to counter low frequency transients.Recongure as necessary to nd the lowesteffective value for the DFSENS parameter.
