The USB interface provides Type-A and Type-B connectors.

Compatible devices using a Type-A connector include a flash drive, keyboard, USB hub and label and ticket printers. The host PC uses a Type-B connector.

3.3.5 Keyboard Interface

Serial Interface

Serial port 2 on the 920i CPU board provides a PS/2-type keyboard interface for use with a remote keyboard. To use the keyboard interface, set the INPUT parameter for Port 2 (under the SERIAL menu) to KEYBD.

Table 3-6 on page 15 summarizes the 920i specific functions provided by the keyboard interface; most other alphanumeric and

navigational keys provide functions equivalent to those typical for PC operation. Menu parameters and serial commands that affect indicator keypad operation (including the KBDLCK, ZERONLY, and KLOCK serial commands) also affect the remote keyboard.

The keyboard interface is not hot-pluggable. Disconnect power to the 920i before plugging the keyboard cable into the Port 2 connector.

The 920i supports keyboard scan codes 1, 2, and 3.

USB Interface

The 920i USB interface board provides a type-A connection for a USB keyboard interface. To use the keyboard interface, set the DEVICE parameter for Port 2 (under the SERIAL menu) to KEYBOARD.

Table 3-6 summarizes the 920i specific functions provided by the keyboard interface; most other alphanumeric and navigational

keys provide functions equivalent to those typical for PC operation. Menu parameters and serial commands that affect indicator keypad operation (including the KBDLCK, ZERONLY, and KLOCK serial commands) also affect the remote keyboard.

3.3.6 Digital I/O

Digital inputs can be set to provide several indicator functions, including keypad. Digital inputs are active low (0 VDC), inactive high (5 VDC).

Digital outputs are typically used to control relays that drive other equipment. Outputs are designed to sink, rather than source, switching current. Each output is a normally open collector circuit, capable of sinking 24 mA when active. Digital outputs are wired to switch relays when the digital output is active (low, 0 VDC) with reference to a 5 VDC supply.

Table 3-7. J2 Pin Assignments (Digital I/O)

Digital inputs and outputs are configured using the DIG I/O menu. See Section 4.11 on page 49 for configuration information. An optional 24-channel digital I/O expansion card, PN 67601, is available for applications requiring more digital I/O channels. Digital I/O points can be configured to count active pulse inputs by setting them to PROGIN and using the iRite

DigInSsBbActivate handler. The fastest pulse rate that can be counted using a digital input is 10Hz (10 pulses per second). More demanding applications can use the pulse input option card (PN 67603) to count pulses in the 4–4000Hz range.

3.7 CPU Board Removal

To remove the 920i CPU board, use the following procedure:

1. Disconnect power to the indicator. Remove backplate as described in Section 3.2 on page 10.

2. Unplug connectors J9, J10, and J11 (serial communications), J2 (digital I/O), P1 (power supply), and connectors to any installed option cards.

3. Remove any installed option cards.

4. Remove the screws and nuts securing the CPU board.

5. Gently lift the CPU board and disconnect connectors J12 (power to display), J4 (ribbon cable), J3 (keypad connector) and the cable in J8 (Port 2 serial port).

6. Remove CPU board from the enclosure. If necessary, cut cable ties to shift cables out of the way.

To replace the CPU board, reverse the above procedure. Be sure to reinstall cable ties to secure all cables inside the indicator enclosure.

3.8 Battery Replacement

The lithium battery on the CPU board maintains the real-time clock and protects data stored in the system RAM when the indicator is not connected to AC power.

Data protected by the CPU board battery includes time and date, truck and tare memory, onboard database information and setpoint configuration.

Use iRev 4 to store a copy of the indicator configuration on a PC before attempting battery replacement. If any data is lost, the indicator configuration can be restored from the PC.

Memory option card data is also protected by a lithium battery. All database information stored on a memory card is lost if the memory card battery fails.

Watch for the low battery warning on the LCD display and periodically check the battery voltage on both the CPU board and on any installed memory option cards. Batteries should be replaced when the indicator low battery warning comes on, or when battery voltage falls to 2.2 VDC. Life expectancy of the battery is 10 years.

Battery Removal

Place the tip of a finger in notched area near the battery retaining spring and slide the battery out of position on the CPU board.

Figure 3-13. Battery Removal

3.8.1 Replacement

Before replacing the battery, place the indicator in setup mode, then press SAVE/EXIT to save battery-backed memory (NVRAM) to flash. This operation saves the latest configuration information, including setpoint values, stored strings and data, and the onboard database, to flash memory.

Return to weigh mode, power off the indicator, and replace the battery. Use care not to bend the battery retaining spring. When power is restored, a message is shown stating that battery-backed memory is corrupt. Press

saved in flash memory. See Figure 3-7 on page 16 for CPU board battery location and orientation (positive side up).

Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer. Dispose of unused batteries according to the manufacturer’s instructions.

920i Programmable Indicator/Controller

Note

IMPORTANT

4.0 Configuration

See the 920i technical manual (PN 67887) for section references not found in this manual.

The 920i 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 an indicator serial port. If there is no serial port on port 2, refer to Section 7.0 on

page 65. Configuration using the menus is described in this section.

Configuration using the serial port can be accomplished using either the serial command set described in Section 11.0 on

page 97 or the iRev 4 configuration utility.

The 920i display and widgets, cannot be accessed through the configuration menus. iRev 4 provides the most complete and efficient configuration interface for the 920i.

4.1 iRev™ Configuration

The iRev configuration utility provides the preferred method for configuring the 920i indicator. iRev 4 runs on a personal computer to set configuration parameters for the indicator. When iRev 4 configuration is complete, configuration data is downloaded to the indicator.

iRev supports both uploading and downloading of indicator configuration data. This capability allows configuration data to be retrieved from one indicator, edited and downloaded to another indicator with an identical hardware configuration.

See Section 6.0 on page 57 for more information about using iRev to configure the 920i.

4.2 Serial Command Configuration

The serial command set can be used to configure the 920i indicator using either a personal computer, terminal, or remote keyboard. Like iRev 4, serial command configuration sends commands to the indicator serial port; unlike iRev 4, serial commands can be sent using any external device capable of sending ASCII characters over a serial connection.

Serial commands duplicate the functions available using the indicator front panel and provide some functions not otherwise available. Serial commands can be used to simulate pressing front panel keys, to configure the indicator, or to dump lists of parameter settings. See Section 11.0 on page 97 for more information about using the serial command set.

4.3 Configuration Switch

To configure the 920i indicator, the indicator must be placed in configuration mode.

Insert non-conductive tool to press switch.

Fillister Head Screw

Figure 4-1. Configure Switch – Universal Model

1. Remove the setup switch access screw on the bottom of the universal enclosure.

2. Insert a small non-conductive tool into the access hole to press the switch. The main menu displays.

3. Set parameters as required for scales/system being used.

4. Once configuration is complete, press the Save and Exit softkey to exit setup mode.

5. Replace the setup switch access screw.

To maintain NTEP certification requirements and to use the scale to record Legal for Trade transactions, the scale must be properly sealed.

* If updating and/or configuring the scale, the seal may need to be broken to enter the menu structure. * Removing or altering the seal voids the NTEP approval. For continued certification the unit must be resealed, by an

authorized agent, when configuration is complete. * There are menus that must be set per NTEP standards, ensure these settings remain NTEP accepted values. * Calibration must be performed by a qualified technician familiar with state and local regulations.

4.6.1 Digital Filtering

Standard digital filtering uses mathematical averaging to eliminate the variant digital readings that the A/D converter sends periodically because of external vibration. Digital filtering does not affect the indicator measurement rate, but does affect the settling time. The selections from 1 to 256 reflect the number of readings averaged per update period. When a reading is encountered that is outside a predetermined band, the averaging is overridden, and the display jumps directly to the new value.

DIGFLTx Parameters

The first three digital filtering parameters, DIGFLT1, DIGFLT2, and DIGFLT3, are configurable filter stages that control the effect of a single A/D reading on the displayed weight. The value assigned to each parameter sets the number of readings received from the preceding filter stage before averaging.

A rolling average is passed to successive filters for an overall filtering effect that is effectively a weighted average of the product of the values assigned to the filter stages (DIGFLT1 x DIGFLT2 x DIGFLT3)

within a time frame corresponding to the sum of the

values (DIGFLT1 + DIGFLT2 + DIGFLT3). Setting the filters to 1 effectively disables digital filtering.

Rattletrap® Filtering

RATTLETRAP digital filtering (RATTRAP parameter set ON) uses a vibration-dampening algorithm to provide a combination of the best features of analog and digital filtering. The RATTLETRAP algorithm eliminates the frequency of a repeating vibration then displays weight equal to the actual weight on the scale less the vibration-induced flaws. It is particularly effective for eliminating vibration effects or mechanical interference from nearby machinery. Using RATTLETRAP filtering can eliminate much more mechanical vibration than standard digital filtering, but will usually increase settling time over standard digital filtering.

Digital Filter Sensitivity and Digital Filter Threshold Parameters

The digital filter can be used by itself to eliminate vibration effects, but heavy filtering also increases settling time. The DFSENS (digital filter sensitivity) and DFTHRH (digital filter threshold) parameters can be used to temporarily override filter averaging and improve settling time:

• DFSENS specifies the number of consecutive scale readings that must fall outside the filter threshold (DFTHRH) before digital filtering is suspended.

• DFTHRH sets a threshold value, in display divisions. When a specified number of consecutive scale readings (DFSENS) fall outside of this threshold, digital filtering is suspended. Set DFTHRH to NONE to turn off the filter override.

Page 36

920i Programmable Indicator/Controller

Setting the Digital Filter Parameters

Fine-tuning the digital filter parameters greatly improves indicator performance in heavy-vibration environments. Use the following procedure to determine vibration effects on the scale and optimize the digital filtering configuration.

1. Place the indicator into setup mode. See Section 4.3 on page 24.

2. Set the digital filter parameters (DIGFLT1–DIGFLT3) to 1.

3. Set DFTHRH to NONE.

4. Return indicator to weigh mode.

5. Remove all weight from the scale and watch the display to determine the magnitude of vibration effects on the scale.

6. Record the weight below which all but a few readings fall. This value is used to calculate the DFTHRH parameter

value in Step 8.

Example: if a heavy-capacity scale (10000 x 5 lb) produces vibration-related readings of up to 50 lb, with occasional spikes to 75 lb, record 50 lb as the threshold weight value.

7. Place the indicator in setup mode and set the DIGFLTx parameters to eliminate the vibration effects on the scale.

(Leave DFTHRH set to NONE.) Find the lowest effective value for the DIGFLTx parameters.

8. Calculate the DFTHRH parameter value by converting the weight value recorded in Step 6 to display divisions:

threshold_weight_value / display_divisions

In the example in Step 6, with a threshold weight value of 50 lb and a display divisions value of 5 lb: 50 / 5 = 10. DFTHRH should be set to 10D for this example.

9. Set the DFSENS parameter high enough to ignore transient peaks. Longer transients (typically caused by lower

vibration frequencies) will cause more consecutive out-of-band readings, so DFSENS should be set higher to counter low frequency transients.

Reconfigure as necessary to find the lowest effective value for the DFSENS parameter.

Example: REFRESH set to 0.1 second and INTERVL set at 60, each weight value takes 6 seconds (0.1 * 60) to be flushed from ROC data REFRESH Refresh interval – specifies the number of seconds between Rate-of-Change samples; Setting: 0.1(default)-60 For applications using the ROC function, the primary scale should be configured with a finer resolution than the rate of change (ROC) units to prevent a

stepwise appearance in the ROC display. The ROC display step size (weight increment between displayed values) can be roughly calculated as follows: (updates_per_ROC_UNIT) * (PRIMARY_resolution / ROC_resolution) Example, with INTERVL=30; REFRESH =0.1; UNITS=MIN; PRIMARY resolution at 0.1 LB and ROC resolution at 1.0 (LB/ MIN)

• INTERVL * REFRESH = 30 * 0.1 = 3.0 seconds per update (ROC data is flushed every 3.0 seconds)

• With UNITS = MIN, there are 20 ROC data updates per ROC time unit: 60 seconds / 3.0 seconds per update

• The resolution ratio of PRIMARY to ROC units is 0.1 (0.1 / 1.0)

• This configuration provides a step size in the ROC display of 2 LB (2 LB increments between displayed values)

Table 4-4. Format Parameters – SPLIT = OFF (Continued)

Multi-Range and Multi-Interval Scales

The 920i supports multi-range and multi-interval scales. Multi-range scales provide two or three ranges, each extending from zero to the maximum capacity specified for the range, that

can specify different scale intervals (graduations). The scale interval changes as the applied weight increases but does not reset to lower range intervals until the scale returns to zero.

Multi-interval scales divide the scale into two or three partial weighing ranges, each with different scale intervals. The scale interval changes with both increasing and decreasing loads applied.

To configure, use the SPLIT parameter to select 2RNG or 3RNG (for multi-range scales), or 2INTVL or 3INTVL (for multiinterval scales). Selecting a SPLIT value allows specification of decimal point, display divisions and maximum capacity for each range or interval.

4.6.3 Unit Conversion Factors

The 920i has the capability to mathematically convert and display weight in other units. Press to scroll through available units.

Set secondary (SECNDR) and tertiary (TERTIA) units using serial commands.

• To configure secondary or tertiary units using the front panel menus, use the Table 4-5 to find the conversion multiplier for the MULT parameter.

Example: if the primary unit is pounds and the secondary unit is short tons, set the MULT parameter to 0.000500.

• To configure secondary or tertiary units using serial commands, use the Table 4-5 to find the conversion multiplier for the SC.SEC.MULT or SC.TER.MULT command.

Example: if the primary unit is pounds and the secondary unit is short tons, send the serial command SC.SEC.MULT= 0.0005<CR> to set the multiplier for the secondary units.

Ensure that the secondary decimal point position is set appropriately for the scale capacity in the secondary units. If the converted value requires more digits than are available, the indicator displays an overflow message (

Setting the units is for the display and printed output, it does not change the defaulted units in the stream format. See Section 4.7.8 on page 40.

Example: if the primary units are short tons, secondary units are pounds, and the secondary decimal point is set to 8888.888, the indicator will overflow 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 five digits to the left of the decimal point to display the 10000 lb secondary units value.

4.7.7 Local/Remote Operation

For truck scale and similar applications, local/remote support provides function equivalent to that of a Legal for Trade remote display with keypad. Scale data from the local indicator is also displayed at the remote unit, and keypad input from the remote allows transactions to be initiated from either the local or remote unit.

To configure for local/remote operation, first set up the local scale (including softkey assignments, truck mode, and database information, as required). Use the SERIAL menu, serial commands, or iRev to set the Local Unit serial parameters shown in

Table 4-13. Configure the remote indicator using the serial parameters listed for the Remote Unit.

4.13 Fieldbus Menu

The Fieldbus menu is only displayed if a DeviceNet, PROFIBUS®, EtherNet/IP, or ControlNet option card is installed. The SWAP parameter on the FLDBUS menu enables byte swapping by the iRite BusCommand handler rather than requiring a SWP (SWAPBYTE) instruction in the PLC. Byte swapping is enabled by default for DeviceNet cards; for all other fieldbus cards, byte swapping is disabled by default.

• BYTE swaps bytes within the word before transmission to the scanner

• WORD swaps words 1 and 2, 3 and 4, within a 4-word packet

• BOTH performs both operations, swapping bytes within a word and swapping words within the packet

• NONE disables swapping

The DATASIZE parameter sets the size of the BusCommand handler data transfers. The default value (8 bytes) matches the default data size specified in the EDS and GSD files, and used by the standard discrete transfer commands. DATASIZE can be set to any value from 2–128 bytes (1–64 words), but the value specified must match the data size set for the PLC Scanner I/O data size.

Figure 4-20. Fieldbus Menu

Parameter Description

SWAP Specifies byte-swapping used for the fieldbus card; Settings: NONE, BYTE, WORD, BOTH (Default for DeviceNet is BYTE; default for all

other cards is NONE)

NOTE: In Version 3.08 firmware, this parameter supports values of YES (byte swapping) or NO. Version 3.09 replaces YES with BYTE, NO with NONE, and adds the values WORD and BOTH.

DATASIZE Data Size – specifies the data size, in bytes, that the BusCommand handler transfers; Settings: 2-12, 8 (default); if parameter is set to a

value other than the default (8 bytes), ensure that it matches the Scanner I/O data size specified for the PLC

Table 4-25. Fieldbus Menu Parameters

4.14 Version Menu

The Version menu can be used to check the installed software version or, by using the Reset Config softkey, to restore all configuration parameters to their factory default values. There are no parameters associated with the Version menu: when selected, the indicator displays the installed software version number.

The Contacts softkey on the Version menu allows display of contact information (see Section 4.8.1 on page 44). If an iQUBE2 scale is configured, a

Diagnostics softkey also provides access to iQUBE2 diagnostic information.

7.5 Loading Configuration Files and Databases

Certain files may take extended periods of time to load directly from a PC to the 920i. For fastest loading times, using a Flash drive is recommended.

It is also recommended to create a folder matching each 920i’s unit ID number, if using multiple 920i units. When loading configuration files, the unit will load the file contained in a folder matching its UID# (the default UID# is 1). If no folder matching the UID is found, the unit will load the first file found.

7.5.1 Loading Configuration Files

When a file is loaded from a USB flash Drive, the calibration is always included and will overwrite existing calibration. To eliminate this, the 920i configuration file should be downloaded to the indicator before calibration is completed.

If loading a configuration file from a UID subdirectory, ensure the configuration file does not change the unit ID. Otherwise, a .COD file in that subdirectory will not be recognized until the UID is manually reverted to its original number.

File names are limited to eight characters.

920i Programmable Indicator/Controller

8.0 Print Format

The 920i provides print formats that determine the format of the printed output when the PRINT key is pressed, a KPRINT serial command is received, or when setpoint push-print or truck weigh-in or weigh-out operations are performed. Supported print formats are: GFMT, NFMT, ACCFMT, SPFMT, TRWIN, TRWOUT, ALERT, AUXFMT1-AUXFMT20, and AUDITFMT. Additionally, two header formats, HDRFMT1 and HDRFMT2, can be inserted into any of the other ticket formats using the

<H2> formatting commands. The particular ticket format used for a given print operation depends on the indicator

and configuration (Table 8-10 on page 73) and the particular operation performed.

Each print format can be customized to include up to 1000 characters of information, such as company name and address, on printed tickets. Use the iRev 4 configuration utility, serial commands, or the indicator front panel (PFORMT menu) to customize the print formats.

8.1 Print Formatting Commands

This section lists commands that can be used to format the 920i print formats. Commands included in the format strings must be enclosed between < and > delimiters. Any characters outside of the delimiters are printed as text on the ticket. Text characters can include any ASCII character that can be printed by the output device.

8.1.1 General Weight Data Commands

Supported Ticket Formats – GFMT, NFMT, TRWIN, TRWOUT, ACCFMT, AUXFMTxx, ALERT

Command Description

<G> Gross weight, current scale

<G#n> Gross weight, scale n

<N> Net weight, current scale

<N#n> Net weight, scale n

<T> Tare weight, current scale

<T#n> Tare weight, scale n

<S> Current scale number

Table 8-1. General Weight Data Commands

Gross, net, tare, accumulator, truck, and setpoint weights can be printed in any configured weight units by adding the following modifiers to the gross, net, and tare weight commands:

/P (primary units) /D (displayed units) /S (secondary units) /T (tertiary units)

If not specified, the current displayed units (/D) is assumed.

Example: To format a ticket to show net weight for Scale #3 in secondary units, use the following command: <N#3/ S>

Formatted weight strings contain a 10-digit weight field (including sign and decimal point, with leading zeros suppressed), followed by a space and a two-digit units identifier. Total field length with units identifier is 12 (or 13) characters.

If printing data to a ticket printer, the command <NLnn> must be put at the end of print format command in order for it print.

8.4 Customizing Print Formats

The following sections describe procedures for customizing print formats using the iRev 4 configuration utility, serial commands, or the front panel (PFORMT menu). See Section 4.7.8 on page 40 for information about custom stream formatting.

8.4.1 Using iRev

The iRev 4 configuration utility provides a ticket formatting grid with a tool bar. The grid allows the construction of the ticket format without using the formatting commands (<NL> and <SP>) required by the front panel or serial command methods. Using iRev 4, type text directly into the grid, then select weight value fields from the tool bar and place them where they will appear on the printed ticket.

Figure 8-1. iRev Print Format Editor

8.4.2 Using the Front Panel

If there is no access to equipment for communication through a serial port or are working at a site where such equipment cannot be used, use the PFORMT menu to customize the print formats

Each print format can be edited from the front panel using a character selection. Use the navigation keys (up, down, left, right) to move around and between the format command line and the character selection list.

920i Programmable Indicator/Controller

8.4.3 Using Serial Commands

Using a PC, terminal, or remote keyboard attached to one of the 920i serial ports, use the serial command set described in

Section 8.1 on page 70 to customize the print format strings.

To view the current setting of a format string, type the name of the print format and press the the current configuration of the GFMT format, type GFMT.FMT and press

Enter. The indicator responds by sending the current

configuration for the gross format:

GFMT.FMT=<G> GROSS<NL>

To change the format, use the GFMT.FMT or NFMT.FMT serial command followed by an equals sign (=) and the modified print format string. For example, to add the name and address of a company to the gross format, send the following serial command:

GFMT.FMT=MOE'S DUMP<NL>2356 EAST HIGHWAY ROAD<NL>SMALLTOWN<NL2><G> GROSS<NL>

A ticket printed using this format might look like the following:

MOE'S DUMP 2356 EAST HIGHWAY ROAD SMALLTOWN

1345 LB GROSS

The ticket above could also be formatted by specifying the company address information in the HDRFMT1 ticket format, then substituting the <H1> command for the address in the GFMT ticket format:

HDRFMT1=MOE'S DUMP<NL>2356 EAST HIGHWAY ROAD<NL>SMALLTOWN<NL2> GFMT.FMT=<H1><G> GROSS<NL>

9.0 Truck Modes

The truck in/out modes are used to handle multiple truck ID numbers and weights. Truck IDs can be up to 16 alphanumeric characters in length.

Six truck modes combine stored ID, keyed tare, and value swapping features in various ways:

Value

Mode Stored IDs Keyed Tares

MODE1 NO YES YES MODE2 NO NO YES MODE3 YES YES YES MODE4 YES NO YES MODE5 YES YES NO MODE6 YES NO NO

OFF

Table 9-1. Truck Mode Features

Stored IDs – keeps a database of truck IDs and weigh-in weights in the indicator’s memory. The indicator can automatically store up to 1000 truck IDs and tares; or it can clear the information after printing a weigh-out ticket. For example, if the same truck seldom crosses the scale, it may not be practical to save its ID number and weigh-in weight. However, if that same truck crosses the scale many times each day, it’s more convenient to store the information in the indicator memory and recall it when needed. Stored IDs and weights are available in modes 3, 4, 5, and 6.

Keyed tares – allows manual entering of the tare weight using the numeric keypad and the in modes 1, 3, and 5. To use keyed tares, an incoming truck must be empty at weigh-in, full at weigh-out.

Swapping

Tare key. Keyed tares are available

Some local regulations require the tare weight to be read from the scale. If so, don’t use the keyed tares feature.

Value swapping – ensures that the lowest of two weight values associated with a particular ID number is used as the tare weight. For example, if a truck crosses the scale fully loaded at weigh-in, then unloads and crosses the scale empty at weighout, the indicator automatically assigns the lesser (empty truck) weight as the tare. Value swapping is available in modes 1, 2, 3 and 4.

9.1 Using the Truck Modes

To select a truck in/out mode:

1. Press the setup switch to enter setup mode.

2. Use the navigation keys to go to the FEATURE menu.

3. Navigate to the TRUCK sub-menu to select the mode.

4. Go

right to the softkeys sub-menu and configure the Weigh In, Weigh Out, and Truck Regs softkeys. These keys are

required when using the truck modes.

920i Programmable Indicator/Controller

Note

10.0 Setpoints

The 920i indicator provides 100 configurable setpoints for control of both indicator and external equipment functions. Setpoints can be configured to perform actions or functions based on specified parameter conditions. Parameters associated with various setpoint kinds can, for example, be configured to perform functions (print, tare, accumulate), to change the state of a digital output controlling indicator or external equipment functions, or to make conditional decisions.

Weight-based setpoints are tripped by values specified in primary units only.

10.1 Batch and Continuous Setpoints

920i setpoints can be either continuous or batch setpoints. Continuous setpoints are free-running: the indicator constantly monitors the condition of free-running setpoints at each A/D

update. The specified setpoint action or function is performed when the designated setpoint parameter conditions are met. A digital output or function assigned to a free-running setpoint continuously changes state, becoming active or inactive, as defined by the setpoint parameters.

Batch setpoints are active one at a time, in an ordered sequence. The 920i can use setpoints to control up to 100 separate batch processing steps.

A digital output associated with a batch setpoint is active until the setpoint condition is met, then latched for the remainder of the batch sequence.

To use batch setpoints, activate the BATCHNG parameter on the SETPTS menu. This parameter defines whether a batch sequence is automatic or manual. AUTO sequences repeat continuously, MANUAL sequences require a BATSTRT signal. The BATSTRT signal can be initiated by a digital input, serial command, an iRite program.

For setpoint kinds that can be used as either continuous or batch setpoints, the BATCH parameter must also be set ON. (Setpoint kinds that can only be used as batch setpoints do not require the BATCH parameter.) If the setpoint is defined but the BATCH parameter is off, the setpoint operates as a continuous setpoint, even during batch sequences.

In applications that contain both batch setpoint routines and continuous setpoints, continuous setpoints should be kept separate from the batch sequence. This is especially true when using CONCUR or TIMER setpoints to perform actions or functions based on the batch sequence. CONCUR and TIMER setpoints should not be included in the referenced START and END setpoint sequence.

the same weight mode as the referenced setpoint %REL Percent Relative Setpoint – performs functions based on a specified percentage of the target value of a

referenced setpoint, using the same weight mode as the referenced setpoint; the actual target value of the %REL

setpoint is calculated as a percentage of the target value of the referenced setpoint RESREL Result Relative – relative to a result setpoint; performs functions based on specified percentage of captured value

of a referenced setpoint, using same weight mode as referenced setpoint; actual target value of RESREL setpoint

is calculated as a percentage of captured value of the referenced setpoint, rather than the target value PAUSE Pause – pauses the batch sequence indefinitely; BATSTRT signal must be initiated to continue the batch process X DELAY Delay – delays batch sequence for a specified time; length of delay (in 0.1 sec) is specified in VALUE parameter X WAITSS Wait for Standstill – suspends the batch sequence until the scale is at standstill X

Setpoints

Kind Description Batch Continuous

COUNTER Counter – specifies number of consecutive batch sequences to perform; counter setpoints should be placed at

beginning of a batch routine AUTOJOG Auto Jog – automatically checks the previous weight-based setpoint to verify the setpoint weight value is satisfied

in a standstill condition; if previous setpoint was not satisfied when at standstill, the AUTOJOG setpoint activates

the digital output of previous weight-based setpoint for a period of time, specified on the VALUE parameter;

auto-jog process repeats until previous weight-based setpoint is satisfied when the scale is at standstill

NOTE: An AUTOJOG digital output is used to signify an auto-jog operation is being performed. AUTO-

JOG should not be assigned to the same digital output as the related weight-based setpoint.

COZ Center of Zero – monitors for a gross zero condition; digital output associated with this setpoint kind is activated

when the referenced scale is a center of zero; no value is required for this setpoint INMOTON In Motion – monitors for an in-motion condition; digital output associated with this setpoint is activated when the

scale is not at standstill; no value is required for this setpoint INRANGE In Range – monitors for an in-range condition; digital output associated with this setpoint is activated when the

scale is within capacity range; no value is required for this setpoint. BATCHPR Batch Processing Signal – digital output associated with this setpoint is activated whenever a batch sequence is

in progress; no value is required for this setpoint TIMER Timer – tracks the progress of a batch sequence based on a timer; timer value (in 0.1 sec) on the VALUE param-

eter, determines the length of time allowed between start and end setpoints; indicator START and END parame-

ters are used to specify the start and end setpoints; if the END setpoint is not reached before the timer expires,

the digital output associated with this setpoint is activated CONCUR Concur – allows a digital output to remain active over a specified portion of the batch sequence; two types of con-

cur setpoints can be configured:

Type 1 (VALUE=0): the digital output associated with this setpoint becomes active when the START setpoint

becomes the current batch step and remains active until the END setpoint becomes the current batch step

Type 2 (VALUE > 0): if a non-zero value is specified for the VALUE parameter, that value represents the timer, (in

0.1 second) for this setpoint; the digital output associated with this setpoint becomes active when the START

setpoint becomes the current batch step and remains active until the timer expires

NOTE: The digital output assigned to the Concur Setpoint should not be used by another Concur

setpoint; this may cause a conflict in setting the output state.

DIGIN Digital Input – requires a specific group of digital inputs to be in low (0 VDC) state to satisfy the setpoint; digital

output associated with this setpoint is held in low (0 VDC) state until inputs selected for digital input mask are all

in a low state AVG Average – performs functions based on calculated average weight over a specified number of A/D samples

NOTE: This setpoint is based on the raw A/D weight value, rather than the rounded value shown on the

display. Example: if 50.0 displays, but the actual raw A/D value is 49.99, the setpoint is not be satisfied.

TOD Time of Day – performs functions when the internal clock time of the indicator matches the specified setpoint time X X DELTA Delta Weight – satisfied when change in weight on the scale is equal to or exceeds the absolute value specified

for the setpoint CHKWEI Checkweigher – allows specification of over- and under-weight value; up to three digital outputs can be

configured to represent overweight, underweight, and accept conditions PLSCNT Pulse Counter – performs functions based on pulse counts received by a pulse input card X X PLSRAT Pulse Rate – performs functions based on the pulse rate received by a pulse input card X ALWAYS Always – setpoint always satisfied; typically used to provide an endpoint for true/false branching batch routines X NEVER Never – setpoint is never satisfied; it is used to branch to a designated setpoint in true/false branching batch

routines in which batch will not continue through the normal sequence of batch setpoints DINCNT Digital Input Count – counts pulses received at the specified digital input X X

Setpoints

Parameter Description

VALUE Setpoint Value – enter a number

TRIP Trip – specifies whether the setpoint is satisfied when the weight is higher or lower than the setpoint value, within a band established

BANDVAL Band Value – setpoints with TRIP=INBAND or OUTBAND, specifies a weight equal to half the band width; band established around the

HYSTER Hysteresis – specifies a band around the setpoint value that must be exceeded before the setpoint, once off, can trip on again;

PREACT Preact – allows the digital output associated with a setpoint to shut off before the setpoint is satisfied to allow for material in suspension;

PREVAL Preact Value – specifies the preact value for setpoints with PREACT set to ON, LEARN, or FLOW; depending on the TRIP setting

PREADJ Preact Adjustment Factor – setpoints with PREACT set to LEARN, specifies a decimal representation of the percentage of error correction

PRESTAB Preact Stabilization Time-Out – setpoints with PREACT set to LEARN, specifies the time, in 0.1-sec intervals, to wait for standstill before

PCOUNT Preact Learn Interval – setpoints with PREACT set to LEARN, specifies the number of batches after which the preact value is

TOLBAND Tolerance band – setpoints with TRIP set to HIGHER or LOWER, specifies a tolerance band around the target weight; if the captured

TOLCNT Tolerance count – setpoints with TRIP set to HIGHER or LOWER, specifies the number of consecutive batch cycles in which the tolerance

RELNUM Relative Number – for relative setpoints, specifies the number of the relative setpoint; Enter Value: 1-100

BATCH Batch – specifies whether the setpoint is used as a batch (ON) or continuous (OFF – default) setpoint CLRACCM Clear Accumulator – specify ON (OFF – default) to clear the accumulator when the setpoint is satisfied CLRTARE Clear Tare – specify ON (OFF – default) to clear the tare when the setpoint is satisfied PSHACCM Push Accumulator – specify ON (OFF – default) to update the accumulator and perform a print operation when the setpoint is satisfied;

PSHPRNT Push Print – specify ON (OFF – default) to perform a print operation when the setpoint is satisfied; specify WAITSS to wait for standstill

PSHTARE Push Tare – specify ON (OFF – default) to perform an acquire tare operation when the setpoint is satisfied

• For weight-based setpoints: Specifies the target weight value, 0–9999999

• For time-based setpoints: Specifies, in 0.1-second intervals, a time value in the range 0–65535

• For COUNTER setpoints: Specifies the number of consecutive batches to be run, 0–65535

• For PLSCNT setpoints, specifies a number of pulses, 0–9999999, received by a pulse input card

• For PLSRAT setpoints, specifies a pulse rate in Hz, 0-65535, received by a pulse input card

around the value, or outside of that band; Settings: HIGHER (default), LOWER, INBAND, OUTBAND In a batch sequence with TRIP=HIGHER, the associated digital output is active until the setpoint value is reached or exceeded; with TRIP=LOWER, the output is active until the weight goes below the setpoint value

setpoint value is VALUE ±BANDVAL; Enter Value: 0-9999999

Enter Value: 0-9999999

Settings: OFF (default)

• ON – adjusts setpoint trip value up or down (depending on the TRIP parameter setting) from setpoint value using a fixed value specified on the PREVAL parameter

• LEARN – can be used to automatically adjust the PREACT value after each batch; it compares the actual weight at standstill to the target setpoint value and adjusts the PREVAL by the PREADJ value times the difference after each batch

• FLOW – provides dynamic compensation for material flow rate in determining when to shut off the digital output; rather than waiting for the specified weight to be reached, FLOW uses the change in weight over time to anticipate when the TRIP minus PREACT weight value will be reached

specified for the setpoint, the setpoint trip value is adjusted up or down by the PREVAL value; Enter Value: 0-9999999

applied (0.5 = 50%, 1.0 = 100%) each time a PREACT adjustment is made; Enter Value: 0-9999999, 0.500000 (default)

adjusting the PREACT value; setting this parameter to a value greater than zero disables the learn process if standstill is not achieved in the specified interval; Enter Value: 0-65535, 0 (default)

recalculated; the default value, 1, recalculates the preact value after every batch cycle; Enter Value: 0-65535, 1 (default)

weight is not within the specified tolerance band, the preact learn function is not applied and the batch is paused (based on the value of the TOLCNT parameter) until restarted or reset; Enter Value: 0-9999999, 0 (default)

band must be exceeded before the batch process is paused; when the specified value is met, the batch is paused and an error message is displayed; the batch must be restarted or reset to clear the error message; the special value of zero means that the batch is never paused for an out-of-tolerance condition; Enter Value: 0-65535, 1 (default)

Target weight for this setpoint is determined as follows:

• REL setpoints, the value of the relative setpoint plus the value (VALUE parameter) of the +REL setpoint

• REL setpoints, the value of the relative setpoint minus the value of the –REL setpoint

• %REL setpoints, the percentage (specified on the VALUE parameter of the %REL setpoint) of the target value of the relative setpoint

• RESREL setpoints, the percentage (specified on the VALUE parameter of the RESREL setpoint) of the captured value of the relative setpoint

specify ONQUIET to update the accumulator without printing

after setpoint is satisfied before printing

NOTE: PSHTARE acquires the tare regardless of the value specified for the REGULAT parameter on the FEATURE menu.

10.3 Batch Operations

Softkeys can be configured to allow operator control of batch operations from the 920i front panel (see Figure 10-10), Softkeys can be configured using iRev 4, serial commands, or the FEATURE menu (see Section 4.8 on page 42).

Figure 10-10. Batching Softkeys

• Setpoint: Display or change assigned setpoints.

Batch Start: Starts batch process.

•

Batch Pause: Pauses an active batch and turns off all digital outputs except those associated with concurrent and timer

• setpoints. Processing is suspended until Batch Start is pressed again. Pressing Batch Start resumes the batch and reenergizes all digital outputs turned off by the

• Batch Reset: Stops and resets an active batch to the beginning of the process.

Batch Stop: Stops an active batch and turns off all associated digital outputs.

To prevent personal injury and equipment damage, software-based interrupts must always be supplemented by emergency stop switches and other safety devices necessary for the application.

Batch Pause.

Batching Switch

The batching switch option, PN 19369, comes as a complete unit in an FRP enclosure, with legend plate, locking stop switch (mushroom button), and a run/start/abort 3-way switch.

Both switches are wired into the indicator’s digital I/O terminal strip as shown in Figure 10-12 on page 94. Each switch uses a separate digital input.

Once cables and switches have been connected to the indicator, use the setup switch to place the indicator in setup mode. Use the digital I/O menu (Section 4.11 on page 49) to configure digital input and output functions.

To begin a batch process, turn the 3-way switch to START momentarily. If the STOP button is pushed during the batch process, the process halts and the button locks in the IN position.

The START switch is ignored while the STOP button is locked in the IN position. The STOP button must be turned counterclockwise to unlock it, then released into the OUT position to enable the 3-way switch.

To restart an interrupted batch from the step where it left off:

1. Unlock STOP button (OUT position)

2. Turn 3-way switch to START

To restart an interrupted batch from the first batch step:

1. Push the STOP button.

2. Turn 3-way switch to ABORT

3. Unlock STOP button (OUT position)

4. Turn 3-way switch to START

To abort an interrupted batch:

1. Push the STOP button.

2. Turn 3-way switch to ABORT.

3. Unlock STOP button (OUT position). A new batch can now be started.
