5 About This Manual This manual is intended for use by service technicians responsible for installing and servicing 120 digital weight indicators. This manual applies to indicators using Version 2.02 of the 120 software. Configuration and calibration of the indicator can be accomplished using the indicator front panel keys, the EDP command set, or Version 3.0 or later of the Revolution configuration utility. See Section 3.1 on page 7 for information about configuration methods. Some procedures described in this manual require work inside the indicator enclosure. These procedures are to be performed by qualified service personnel only. Authorized distributors and their employees can view or download this manual from the Rice Lake Weighing Systems distributor site at The Operator Card included with this manual provides basic operating instructions for users of the 120. Please leave the Operator Card with the indicator when installation and configuration are complete. 1.0 Introduction The 120 is a single-channel digital weight indicator housed in a durable plastic enclosure. The indicator front panel consists of a large (.8 in, 20 mm), six-digit, seven-segment LED display and five-button keypad. Features include: Drives up to four 350Ω or eight 700Ω load cells Supports 4- and 6-wire load cell connections Electronic data processing (EDP) port for full duplex, RS-232 communications at up to bps Printer port for output-only RS-232 and 20 ma current loop communications at up to 9600 bps The 120 is NTEP-certified for Classes III and III L at 6,000 divisions. See Section 7.8 on page 36 for detailed specifications. 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 as required, using the LED annunciators described in Section 1.3 on page 2 to indicate scale status and the type of weight value displayed. Once configuration is complete and a legal seal is affixed to the back of the indicator, this is the only mode in which the 120 can operate. See Section on page 3 for more information about normal mode operations. Panel mode Panel mode allows the time, date, consecutive number, and consecutive number start-up value to be set without entering configuration mode. To enter panel mode, press and hold the GROSS/NET key until the TIME menu is shown. See Section on page 4 for more information about panel mode. Configuration mode Most of the procedures described in this manual require the indicator to be in configuration mode, including configuration and calibration. To enter configuration mode, remove the large fillister head screw from the enclosure backplate. Insert a screwdriver or a similar tool into the access hole and press the setup switch once. The indicator display changes to show the word CONFIG. Test mode Test mode provides a number of diagnostic functions for the 120 indicator. Like setup mode, test mode is entered using the setup switch. See Section 7.7 on page 35 for more information about entering and using test mode. Introduction 1

6 1.2 Front Panel Keypad Figure 1-1 shows the 120 keypad and LED annunciators. The symbols shown under the keys (representing up, down, enter, left, right) describe the key functions assigned in configuration and panel modes. In these modes, the keys are used to navigate through menus, select digits within numeric values, and increment/decrement values. See Section on page 8 for information about using the front panel keys in configuration mode. Figure Front Panel 1.3 LED Annunciators The 120 display uses a set of eight LED annunciators to provide additional information about the value being displayed: 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 specified motion band. Some operations, including tare 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 information displayed). The lb and kg LEDs function as primary and secondary units annunciators for some combinations 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 3 shows which annunciators are used for all combinations of configured primary and secondary units. For example: If the primary unit is pounds (lb) and the secondary unit is kilograms (kg), the lb LED is lit for primary units, 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 primary units, kg for secondary units. There is no LED for short tons, so the kg LED is used as the secondary units annunciator. If the primary unit is short tons (tn) and the secondary unit is pounds (lb), the lb LED is lit for primary units (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 Installation Manual

11 3.0 Configuration To configure the 120 indicator, the indicator must be placed in setup mode. The setup switch is accessed by removing the left fillister head SETUP SWITCH screw on underside of the enclosure and removing the rectangular switch cover plate. Switch position is changed by inserting a screwdriver into the access hole and pressing the switch. When the indicator is placed in setup mode, the word CONFIG is shown on the display. The CONFIG menu is the first of nine main menus FILLISTER-HEAD SCREW used to configure the indicator. Detailed descriptions of these menus are given in Section 3.2. When configuration is complete, return to the CONFIG menu and press the (ZERO) key to exit setup mode, then replace the setup switch access screw. 3.1 Configuration Methods The 120 indicator can be configured by using the front panel keys to navigate through a series of configuration menus or by sending commands or configuration data to the EDP port. Configuration using the menus is described in Section Configuration using the EDP port can be accomplished using the EDP command set described in Section 5.0 or by using the Revolution III configuration utility Revolution Configuration The Revolution III configuration utility provides the preferred method for configuring the 120 indicator. Revolution runs on a personal computer to set configuration parameters for the indicator. When Revolution configuration is complete, configuration data is downloaded to the indicator. Figure 3-1. Sample Revolution Configuration Display Revolution III supports both uploading and downloading of indicator configuration data. This capability allows configuration data to be retrieved from one indicator, edited, then downloaded to another. To use Revolution III, do the following: 1. Install Revolution III (Version 3.1 or later) on an IBM-compatible personal computer running Windows 98 or later. Minimum system requirements include a processor speed of at least 166MHz, 32MB of memory (64MB recommended, required for NT4, 2000, XP), and at least 40MB of available hard disk space for 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 III program. Figure 3-1 shows an example of one of the Revolution configuration displays. Revolution III provides online help for each of its configuration displays. Parameter descriptions provided in this manual for front panel configuration can also be used when configuring the indicator using Revolution: the interface is different, but the parameters set are the same. Configuration 7

12 3.1.2 EDP Command Configuration The EDP command set can be used to configure the 120 indicator using a personal computer, terminal, or remote keyboard. Like Revolution, EDP command configuration sends commands to the indicator EDP port; unlike Revolution, EDP commands can be sent using any external device capable of sending ASCII characters over a serial 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 configure the indicator, or to dump lists of parameter settings. See Section 5.0 on page 23 for more information about using the EDP command set Front Panel Configuration The 120 indicator can be configured using a series of menus accessed through the indicator front panel when the indicator is in setup mode. Table 3-1 summarizes the functions of each of the main menus. Menu Table Menu Summary 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 TARE key ( ) serves as an Enter key for selecting parameter values within the menus. A label under each of these keys identifies the direction provided by the key when 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 first on the display. To change a parameter value, scroll left or right to view the values for that parameter. When the desired value appears on the display, press to select the value and move back up one level. NOTE: You must press to save the selected value. The 120 does not automatically save the last-displayed value. To edit numerical values, press (rightmost digit will flash), then use the navigation keys to select the digit and to increment or decrement the value (see Figure 3.2). When done, press again to save the edited value.

Specifies the number of full scale graduations. The value entered must be in the range and should be consistent with legal requirements and environmental limits on system resolution. To calculate GRADS, use the formula, GRADS = Capacity / Display Divisions. Display divisions for primary and secondary units are specified on the FORMAT menu. Zero track band. Automatically zeroes the scale when within the range specified, as long as the input is within the configured zero range (ZRANGE parameter). Selections are ± display divisions. Maximum legal value varies depending on local regulations. Zero range. Selects the range within which the scale can be zeroed. The 1.9% selection is ± 1.9% around the calibrated zero point, for a total range of 3.8%. Indicator must be at standstill to zero the scale. Use 1.9% for legal-for-trade applications. Motion band. Sets the level, in display divisions, at which scale motion is detected. If motion is not detected for 1 second or more, the standstill symbol lights. Some operations, including print, tare, and zero, require the scale to be at standstill. Maximum legal value varies depending on local regulations. If OFF is selected, ZTRKBN should also be set to OFF. Overload. Determines the point at which the display blanks and an out-of-range error message is displayed. Maximum legal value varies depending on local regulations. Sample rate. Selects measurement rate, in samples per second, of the analog-to-digital converter. Lower sample rate values provide greater signal noise immunity. Digital filtering. Selects the digital filtering rate used to reduce the effects of mechanical vibration from the immediate area of the scale. Choices indicate the number of A/D conversions that are averaged to obtain the displayed reading. A higher number gives a more accurate display by minimizing the effect of a few noisy readings, but slows down the settling rate of the indicator. See Section 7.6 on page 34 for more information on digital filtering. Digital filter cutout sensitivity. Specifies the number of consecutive readings that must fall outside the filter threshold (DFTHRH parameter) before digital filtering is suspended. If NONE is selected, the filter is always enabled.

In GO mode, the indicator goes into operation immediately after a brief power up display test. In DELAY mode, the indicator performs a power up display test, then enters a 30-second warm up period. If no motion is detected during the warm up period, the indicator becomes operational when the warm up period ends; if motion is detected, the delay timer is reset and the warm up period repeated. Regulatory mode. Specifies the regulatory agency having jurisdiction over the scale site. OIML, NTEP, and CANADA modes allow a tare to be acquired at any weight greater than zero. NONE allows tares to be acquired at any weight value. OIML, NTEP, and CANADA modes allow a tare to be cleared only if the gross weight is at no load. NONE allows tares to be cleared at any weight value. NTEP and OIML modes allow a new tare to be acquired even if a tare is already present. In CANADA mode, the previous tare must be cleared before a new tare can be acquired. NONE, NTEP and CANADA modes allow the scale to be zeroed in either gross or net mode as long as the current weight is within the specified ZRANGE. In OIML mode, the scale must be in gross mode before it can be zeroed; pressing the ZERO key in net mode clears the tare. Consecutive numbering. Allows sequential numbering for print operations. The consecutive number value is incremented following each print operation. The initial value of this parameter is set to the start up value specified on the CONSTU parameter. Changing either CONSTU or CONSNU immediately resets the consecutive number used for printing. Consecutive number start up value. Specifies the initial consecutive number (CONSNU) value used when the indicator is powered on. Table 3-6. Program Menu Parameters Configuration 17

Calibration (CALIBR) Menu 4.1 Front Panel Calibration To calibrate the indicator using the front panel, do the following: 1. Place the indicator in configuration mode (display reads CONFIG) and remove all weight from the scale platform. If your test weights require hooks or chains, place the hooks or chains 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 calibrate zero. The indicator displays *CAL* while calibration is in progress then the display goes to (WVAL). 4. With WVAL displayed, place test weights on the scale and press to show the test weight value. Use the procedure shown in Figure 4-2 to enter the actual test weight, then press to save the value and go to span calibration (WSPAN). 5. With WSPAN displayed, press to calibrate span. The indicator displays *CAL* while calibration is in progress, then the display goes to (REZERO). 6. The REZERO function is used to remove a calibration offset when hooks or chains are used to hang the test weights. Note: If no other apparatus was used to hang the test weights during calibration, remove the test weights and go to Step 7. If hooks or chains were used during calibration, remove these and the test weights from the scale. With all weight removed, press to rezero the scale. This function adjusts the zero and span calibration values. The indicator displays *CAL* while the zero and span calibrations are adjusted. 7. Press until the display reads EXIT Y, then press to exit configuration mode. When editing numeric values, press to allow numeric mode change entry, then press or to change the digit selected. Press or to increment or decrement the value of the flashing selected digit. Press to save the value entered and return to the level above. Figure 4-2.

26 4.2 EDP Command Calibration To calibrate the indicator using EDP commands, the indicator EDP port must be connected to a terminal or personal computer. See Section on page 5 for EDP port pin assignments; see Section 5.0 on page 23 for more information about using EDP commands. Once the indicator is connected to the sending device, do the following: 1. Place the indicator in configuration mode (display reads CONFIG) and remove all weight from the scale platform. If your test weights require hooks or chains, place the hooks or chains on the scale for zero calibration. 2. Send the WZERO EDP command to calibrate zero. The indicator displays *CAL* while calibration is in progress. NOTE: During EDP command calibration, the *CAL* message remains on the display. The OK response is returned when calibration is complete. 3. Place test weights on the scale and use the WVAL command to enter the test weight value in the following format: WVAL=nnnnnn<CR> 4. Send the WSPAN EDP command to calibrate span. The indicator displays *CAL* while calibration is in progress. 5. To remove an offset value, clear all weight from the scale, including hooks or chains used to hang test weights, then send the REZERO EDP command. The indicator displays *CAL* while the zero and span calibrations are adjusted. 6. Send the KUPARROW EDP command to exit configuration mode Installation Manual

27 5.0 EDP Commands The 120 indicator can be controlled by a personal computer or remote keyboard connected to the indicator EDP port. Control is provided by a set of EDP commands that can simulate front panel key press functions, display and change setup parameters, and perform reporting functions. The EDP port provides the capability to print configuration data or to save that data to an attached personal computer. This section describes the EDP command set and procedures for saving and transferring data using the EDP port. 5.1 The EDP Command Set The EDP command set includes key press commands, mode commands, reporting commands, the RS special function command, and parameter setting commands. The indicator responds to most EDP commands by sending the message OK. The OK response verifies that the command was received and has been executed. (Pressing ENTER after processing a valid EDP command repeats the previous command.) If the command is unrecognized or cannot be executed, the indicator responds with??. The following sections list the commands and command syntax used for each of these groups Key Press Commands Key press EDP commands (see Table 5-1) simulate pressing the front panel indicator keys. These commands can be used in both configuration and weighing mode. Command KZERO KGROSSNET KTARE KUNITS KPRINT Function In weighing mode, press the ZERO key In weighing mode, press the GROSS/ NET key In weighing mode, press the TARE key In weighing mode, press the UNITS key In weighing mode, press the PRINT key Table 5-1. Key Press EDP Commands Reporting Commands Reporting commands (Table 5-2) send specific information to the EDP port. These commands can be used in both configuration mode and normal mode. P RS Command Function Write current displayed weight with units identifier Reset software Table 5-2. EDP Reporting Commands The RS Command The RS (reset configuration) command can be used to restore all configuration parameters to their default values. Before issuing this command, the indicator must be placed in test mode (press and hold setup switch for approximately three seconds to enter test mode). This command is equivalent to using the DEFLT function on the TEST menu. See Section 7.7 on page 35 for more information about test mode and using the TEST menu. NOTE: All load cell calibration settings are lost when the RS command is run Parameter Setting Commands Parameter setting commands allow you to display or change the current value for a particular configuration parameter (Tables 5-3 through 5-8). Current configuration parameter settings can be displayed in either configuration mode or normal mode using the following syntax: command<enter> Most parameter values can be changed in configuration mode only. Use the following command syntax when changing parameter values: command=value<enter> where value is a number or a parameter value. Use no spaces before or after the equal (=) sign. If you type an incorrect command or value, the display reads??. Changes to the parameters are saved as they are entered but typically do not take effect until you exit configuration mode. For example, to set the motion band parameter to 5, type the following: MOTBAND=5D<ENTER> Command DUMPALL VERSION Function List all parameter values Write 120 software version Table 5-2.

30 5.2 Saving and Transferring Data Connecting a personal computer to the 120 EDP port allows you to save indicator configuration data to the PC or to download configuration data from the PC to an indicator. The following sections describe the procedures for these save and transfer operations Saving Indicator Data to a Personal Computer Configuration data can be saved to a personal computer connected to the EDP port. The PC must be running a communications program such as PROCOMMPLUS. See Section on page 5 for information about serial communications wiring and EDP port pin assignments. When configuring the indicator, ensure that the values set for the BAUD and BITS parameters on the SERIAL menu match the baud rate, bits, and parity settings configured for the serial port on the PC. Set the PRNDES parameter to EDP. To save all configuration data, place the indicator in configuration mode and send the DUMPALL EDP command to the indicator. The 120 responds by sending all configuration parameters to the PC as ASCII-formatted text Downloading Configuration Data from PC to Indicator Configuration data saved on a PC or floppy disk can be downloaded from the PC to an indicator. This procedure is useful when a number of indicators with similar configurations are set up or when an indicator is replaced. To download configuration data, connect the PC to the EDP port as described in Section Place the indicator in configuration mode and use the PC communications software to send the saved configuration data to the indicator. When transfer is complete, calibrate the indicator as described in Section 4.0 on page 21. NOTES: Calibration settings are included in the configuration data downloaded to the indicator. If the receiving indicator is a direct replacement for another 120 and the attached scale is not changed, recalibration is not required. When downloading configurations that include changed serial communications settings, edit the data file to place the serial communications changes at the end of the file. Communication between the PC and indicator will be lost once the indicator receives settings for baud rate (BAUD parameter) or data bits and parity (BITS parameter) that do not match those configured for the PC Installation Manual
