Page 13

2.0 Installation

This section describes procedures for connecting load cell, digital I/O, and serial communications cables to

920i indicator. Assembly drawings and

the replacement parts lists for the universal model are included for the service technician. See

Section 10.12

on page 117 for dimension drawings of the all models.

• Use a wrist strap to ground yourself and protect components from electrostatic discharge (ESD) when working inside the indicator enclosure.

• This unit uses double pole/neutral fusing which could create an electric shock hazard. Procedures requiring work inside the indicator must be performed by qualified service personnel only.

• The supply cord serves as the power disconnect for the

920i. The power outlet

supplying the indicator must be installed near the unit and be easily accessible.

2.1 Unpacking and Assembly

Immediately after unpacking, visually inspect the 920i to ensure all components are included and undamaged. The shipping carton should contain the indicator, this manual, and a parts kit. If any parts were damaged in shipment, notify Rice Lake Weighing Systems and the shipper immediately.

See Section 2.10 on page 14 for parts kit contents.

2.2 Enclosure Disassembly

The indicator enclosure must be opened to install option cards and to connect cables for installed option cards.

The 920i has no on/off switch. Before opening the unit, ensure the power cord is disconnected from the power outlet.

Ensure power to the indicator is disconnected, then place the indicator face-down on an antistatic work mat. Remove the screws that hold the backplate to the enclosure body, then lift the backplate away from the enclosure and set it aside.

2.3 Cable Connections

The universal model of the 920i provides six cord grips for cabling into the indicator: one for the power cord, five to accommodate cabling for option cards. Install plugs in all unused cord grips to prevent moisture from entering the enclosure.

2.3.1 Cable Grounding

Except for the power cord, all cables routed through the cord grips should be grounded against the indicator enclosure. Do the following to ground shielded cables:

• Use the lockwashers, clamps, and kep nuts provided in the parts kit to install grounding clamps on the enclosure studs adjacent to cord grips. Install grounding clamps only for cord grips that will be used; do not tighten nuts.

• Route cables through cord grips and grounding clamps to determine cable lengths required to reach cable connectors. Mark cables to remove insulation and shield as described below:

• For cables with foil shielding, strip insulation and foil from the cable half an inch (15 mm) past the grounding clamp (see Fold the foil shield back on the cable where the cable passes through the clamp. Ensure silver (conductive) side of foil is turned outward for contact with the grounding clamp.

• For cables with braided shielding, strip cable insulation and braided shield from a point just past the grounding clamp. Strip another half inch (15 mm) of insulation only to expose the braid where the cable passes through the clamp (see

Foil (silver side out)

• For load cell cables, cut the shield wire just past the grounding clamp. Shield wire function is provided by contact between the cable shield and the grounding clamp.

• Route stripped cables through cord grips and clamps. Ensure shields contact grounding clamps as shown in

Figure 2-1. Tighten

grounding clamp nuts.

• Finish installation using cable ties to secure cables inside of indicator enclosure.

2.3.2 Load Cells

To attach cable from a load cell or junction box to an installed A/D card, route the cable through the cord grip and ground the shield wire as described in Section 2.3.1 on page 7.

Next, remove connector J1 from the A/D card. The connector plugs into a header on the A/D card (see Figure 2-2). Wire the load cell cable from the load cell or junction box to connector J1 as shown in Tab le 2-1.

When connections are complete, reinstall load cell connector on the A/D card and use two cable ties to secure the load cell cable to the inside of the enclosure.

Digital inputs can be set to provide many indicator functions, including all keypad functions. 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.

2.9 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 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.

NOTE: 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 ten years.

Replacement Procedure

For best results, replace the battery while in weigh mode and with AC power applied. Use care not to

bend the battery retaining spring.

If the battery must be replaced with power removed, do the following immediately after restoring power:

1. Place indicator in setup mode.

2. Go to the Version Menu and press the Reset

Config

softkey. If connected using iRev, configuration can be reset by using monitor mode to enter the RESETCONFIGURATION command followed by the RS command.

See Figure 2-5 on page 10 for CPU board battery location and orientation (positive side up).

Risk of explosion if battery is replaced with incorrect type. Dispose of batteries per manufacturer instruction.

3.0 Configuration

To configure the 920i indicator, the indicator must be placed in setup mode. The setup switch is accessed by removing the large fillister head screw on the backplate of the universal and deep enclosures. Switch position is changed by inserting a screwdriver into the access hole and pressing the switch.

When the indicator is placed in setup mode, a series of menus is shown across the top of the display, along with the words

Scale Configuration. The SCALES menu

is highlighted as the first used to configure the indicator. Detailed descriptions of these menus are provided in

Section 3.2.

3.1 Configuration Methods

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. Configuration using the menus is described in Section 3.1.3.

Configuration using the serial port can be accomplished using either the serial command set described in utility.

NOTE: Some configuration parameters, such as those

used to configure the be accessed through the configuration menus. provides the most complete and efficient configuration interface for the

3.1.1 iRev Configuration

The iRev configuration utility provides the preferred method for configuring the on a personal computer to set configuration parameters for the indicator. When 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, then downloaded to another indicator with an identical hardware configuration.

When configuration is complete, press the Exit or Save

and Exit

softkey to exit setup mode, then replace the

setup switch access screw.

•The Exit softkey exits setup mode without saving parameter changes to NV RAM. Changes made to the configuration remain in the system until indicator power is cycled.

• Save and Exit writes all parameter changes to NV RAM before returning to normal mode.

Figure 3-1. iRev Hardware Configuration Display

To use iRev, do the following:

1. Install iRev on an IBM-compatible personal computer. See

Section 5.0 on page 54 for

detailed hardware and software requirements.

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

3. Power up the PC and the indicator. Use the setup switch to place the indicator in setup mode.

4. Start the iRev program.

iRev 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

iRev: The

interface is different, but the parameters set are the same.

See Section 5.0 on page 54 for more information about using iRev to configure the 920i.

Configuration 19

Page 26

3.1.2 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, serial

command configuration sends commands to the indicator serial port; unlike

iRev, 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 9.0 on page 84 for more

information about using the serial command set.

3.1.3 Front Panel Configuration

Use the CONFIG submenu under the SCALES menu to configure A/D scales. For example, in an indicator with a single-channel A/D card installed in Slot 1, the Scale Configuration display will show the A/D listed

Slot 1 Channel 1) under the AVAILABLE A/D’s column.

( Use the press the center softkey,

left navigation key to select the A/D, then

AVAILABLE A/D’s column, the center

Done, as shown in Figure 3-2.

Press Done to exit the Scale Configuration display.

See Section 10.4 on page 106 for information about configuring serial scales.

3.1.4 Multi-Range and Multi-Interval Scales

The 920i supports multi-range and multi-interval scales of either two or three ranges or intervals.

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

3.1.5 Total Scale Configuration

The output of two or more A/D scales or iQUBE systems can be configured to function as a total scale. Once configured and calibrated, the total scale can be used as a source for other system functions, including streaming, setpoints, print formatting, and analog output.

To set up a total scale from the indicator front panel, use the scale configuration display (see

Figure 3-2) to select the A/D scales or iQUBE systems to configure as a total scale. (Use the available A/D scales or

Change Type softkey to show

iQUBE systems; use the right

navigation key to select the total scale sources.) In

iRev, assign the total scale to an unused position then

select source scales from the existing A/D scales or

iQUBE systems.

Figure 3-2. Scale Configuration Display

20 920i Installation Manual

The FORMAT configuration of the total scale (see Figure 3-5 on page 26) should match that of the source scales. However, the value specified for the total scale GRADS parameter should be specified as the sum of the GRADS values for the source scales. For example: if SCALE 1 is set to GRADS=10000, SCALE 2 to GRADS=5000, SCALE 3 (the total scale) should be set to 15000 grads.

The total scale will show an overrange indication if the maximum capacity of any source scale is exceeded, and show dashes if any source scale reads a negative value. Source scales will respond to Tare and Zero operations performed on the total scale.

1.9% around the calibrated zero point, for a total range of 3.8%. Indicator must be at standstill to zero the scale. Use the default value for legal-for-trade applications.

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 this parameter is set to 0 the standstill annunciator does not light; operations normally requiring standstill (zero, tare, print) are performed regardless of scale motion. If 0 is selected, ZTRKBND must also be set to 0.

Specifies the length of time the scale must be out of motion, in 0.1-second intervals, before the scale is considered to be at standstill. Values greater than 10 are not recommended.

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.

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 per update 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.

NOTE: When configuring non-A/D scales, set the DIGFLTx parameters to 1 to disable filtering.

See Section 10.9 on page 114 for more information about 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.

See Section 10.9 on page 114 for more information about digital filtering.

Digital filter cutout threshold. Specifies the filter threshold, in display divisions. When a specified number of consecutive scale readings (DFSENS parameter) fall outside of this threshold, digital filtering is suspended. If NONE is selected, the filter is always enabled.

See Section 10.9 on page 114 for more information about digital filtering.

Enables RATTLETRAP® digital filtering. RATTLETRAP is most effective at filtering repeating vibrations caused by mechanical noise from nearby machines but may increase settling times over standard digital filter selections.

Sample rate. Selects measurement rate, in samples per second, of the analog-to-digital converter. Lower sample rate values provide greater signal noise immunity: the default 120 Hz value may be too fast to provide the desired stability in some static weighing applications.

NOTE: The maximum total sample rate for all configured A/D channels—the sum of the sample rates for all scales—is 1200 Hz. For example, up to ten scales can be configured with 120 Hz sample rates, or up to twenty scales with 60 Hz sample rates.

Rate of Change (ROC) Units Parameters

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)

For 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):

20 * 0.1 = 2

Note that setting both PRIMARY and ROC display resolutions to 1 LB would have resulted in a step size of 20 LB.

• 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.

• INDUST provides a set of subparameters to allow customization of tare, clear, and print functions in non-legal-for-trade scale installations. See Level 4 parameter descriptions

4.0 Calibration

The 920i can be calibrated using the front panel, serial commands, or iRev. Each method consists of the following steps:

• Zero calibration

• Entering the test weight value

• Span calibration

• Optional five-point linearization

• Optional rezero calibration for test weights using hooks or chains

The following sections describe the calibration procedure for each of the calibration methods. See the iQUBE Installation Manual, PN 77224, for information about configuring iQUBE-attached scales.

4.1 Gravity Compensation

Gravity compensation for latitude and elevation is available for the 920i. To calibrate with gravity compensation, the LOCALE parameter under the FEATURE menu must be set ON, and the LATUDE (latitude) and ELEVAT (elevation, in meters) parameters set before calibrating the indicator (see

Figure 3-11 on page 38).

If the indicator is later installed at a different location, gravity compensation can be applied to a pre-calibrated indicator by adjusting the LATUDE and ELEVAT parameters.

4.2 Front Panel Calibration

The CALIBR submenu (under the SCALES menu,

Figure 4-2) is used to calibrate the 920i. The zero,

see span, and linear calibration point displays provide a set of softkeys used specifically for calibration procedures:

+/– Toggles to allow entry of negative or

positive values

Last Zero Recalls the last established zero value

to allow calibration without removing tests weights or product from scale.

Calibrate Performs calibration for the selected

point

Tem p Z e r o Temporarily zeroes the displayed

weight of a non-empty scale. After span calibration, the difference between the temp zero and the previously calibrated zero value is used as an offset.

2. Send the SC.WZERO#n serial command (where n is the number of the scale) to calibrate zero.

3. Place test weights on the scale and use the SC.WVAL command to enter the test weight value in the following format:

SC.WVAL#n=vvvvv<CR>

4. Send the SC.WSPAN#n serial command to calibrate span.

5. Up to five linearization points can be calibrated between the zero and span calibration values. Use the following commands to set and calibrate a single linearization point:

SC.WLIN#n.V1=vvvvv<CR> SC.WLIN#n.C1<CR>

The SC.WLIN#n.V1 command sets the test weight value (vvvvv) for linearization point 1. The SC.WLIN#n.C1 command calibrates the point. Repeat using the SC.WLIN#n.Vx and SC.WLIN#n.Cx commands as required for additional linearization points.

6. To remove an offset value, clear all weight from the scale, including hooks or chains used to hang test weights, then send the SC.REZERO#n serial command.

5.5 Connecting to the Indicator

Connect the PC serial port to port 2 of the 920i. Return to the Hardware Configuration display, then click on

Connect icon in the toolbar. iRev attempts to

the establish communications to the indicator.

Once communications is established, iRev queries the indicator configuration to determine whether the indicator hardware matches the virtual hardware configured in the current matches, the Hardware Configuration section of

iRev file. If the hardware

iRev

is disabled, preventing further changes.

If the hardware does not match, you are given the option of either canceling the connect operation or overwriting the

iRev hardware configuration with the

actual indicator hardware configuration.

5.5.1 Downloading to the Indicator

The Download Configuration function on the iRev Communications menu allows an iRev configuration file (with or without scale calibration data), setpoint data, widgets, database tables, or an

iRite program file

to be downloaded to a connected indicator in setup mode.

The Download Current Display function on the Communications menu allows you to download only the currently displayed object, such as the parameter set for one scale of a multi-scale configuration.

Because less data is transferred using Download Current

Display

, it is typically faster than a full configuration download, but there is an increased possibility that the download may fail due to dependencies on other objects. If the download fails, try performing a complete download using the

Download Configuration

function.

5.5.2 Uploading Configuration to iRev

The Upload Configuration function on the iRev Communications menu allows the existing configuration of a connected indicator to be saved to a file on the PC. Once saved, the configuration file provides a backup that can be quickly restored to the indicator if needed. Or, the file can be edited within

iRev, then downloaded back to the indicator.

NOTE: The indicator must be in setup mode before uploading or downloading data.

5.6 Installing Software Upgrades

New releases of the 920i system software can be downloaded and installed using an internet connection and the Rice Lake Web Update application.

NOTE: Before upgrading to a new version of 920i system

software, ensure that a copy of the current indicator configuration has been saved using

iRev. Reloading the

system software requires a RESETCONFIGURATION function and resets all configuration and calibration values to their factory defaults.

6.0 Print Formatting

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 <H1> and <H2>formatting commands. The particular ticket format used for a given print operation depends on the indicator configuration (see page 59) and the particular operation performed.

Each print format can be customized to include up to 1000 characters of information, such as company name and

™

iRev

address, on printed tickets. You can use the

configuration utility, serial commands, or the indicator front

panel (PFORMT menu) to customize the print formats.

6.1 Print Formatting Commands

Tabl e 6-1 lists commands you can use 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.

utility, serial commands, or the front panel (PFORMT menu. See

Section 10.6 on page 107 for information

about custom stream formatting.

6.3.1 Using iRev

The iRev configuration utility provides a ticket formatting grid with a tool bar. The grid allows you to construct the ticket format without using the formatting commands (<NL> and <SP>) required by the front panel or serial command methods. Using

iRev, you can type text directly into the grid, then

select weight value fields from the tool bar and place them where you want them to appear on the printed ticket.

Each print format can be edited from the front panel using a character selection like that shown in Figure 6-3. Use the navigation keys (up, down, left,

right) to move around and between the format

command line and the character selection list.

Figure 6-3. Print Formatting Character Selection Display

• To add a character: position the cursor in the format where you want to add the character. Use

up key to return to the character selection

the list, use the navigation keys to highlight the character to add, then press

enter. The new

character is added to the left of the current cursor location in the format string.

• To add a blank space to a string, position the cursor to the right of where the space is to be inserted in the format string, highlight the

character in the selection list, and press enter.

• To delete a character, position the cursor to the right of the character to be deleted from the format string, then press the

CLR key.

• To add a special character, insert the < and > delimiter characters from the selection list. Use the numeric keypad to insert the decimal ASCII value (1–255) of the character between the delimiters. For example, insert

<2> to add the

STX character to the print format.

To save the edited format string, position the cursor in the format string and press enter. Softkeys shown on the character selection display provide additional functions:

Default Restores the string to its default value.

Home Positions cursor at the beginning of the

format string.

Cancel Exits without saving changes to the

format string.

End Positions cursor at the end of the format

string.

Restore Restores the string to its previously

saved value.

A Print Test softkey is shown under the FMT parameter after exiting the character selection display. If a printer is attached, this key can be used to verify the edited string format before exiting setup mode.

NOTE: The Print Test softkey is not available for the HDRFMTx formats. These formats can be output only when inserted into one of the printable ticket formats by using the <H1> or <H2> print format commands.

Print Formatting 61

Page 68

6.3.3 Using Serial Commands

With a personal computer, terminal, or remote keyboard attached to one of the 920i serial ports, you can use the serial command set described in

Tabl e 6-1 on page 57 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 enter key. For example, to check 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, you could 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>

7.0 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 7-1. Truck Mode Features

Stored IDs let you keep a database of truck IDs and

Swapping

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 allow you to manually enter the tare

weight using the numeric keypad and the

TARE key.

Keyed tares are available in modes 1, 3, and 5. To use keyed tares, an incoming truck must be empty at weigh-in, full at weigh-out.

NOTE: 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 weigh-out, the indicator automatically assigns the lesser (empty truck) weight as the tare. Value swapping is available in modes 1, 2, 3, and 4.

7.1 Using the Truck Modes

To select a truck in/out mode, press the setup switch to enter setup mode. Use the navigation keys to go to the FEATURE menu, then to the TRUCK submenu to select the mode.

Next, go right to the SOFTKEYS submenu and configure the

Weigh In, Weigh Out, and Tr u c k Regs

softkeys. These keys are required when using the truck modes.

Figure 7-1. 920i Display, showing Truck Mode Softkeys

7.2 Using the Truck Regs Display

The Truck Regs display is shown by pressing the Truck Regs softkey in weighing mode. The display contains an alphabetical list of stored truck IDs, weigh-in weights (in primary units), and the time and date of the weigh-in transaction (see

NOTE: If a non-zero setpoint password is configured (SPPWD parameter on the FEATURE menu), you must enter the password before any truck register entries can be deleted.

Section 6.2 on page 59).

7.3 Weigh-In Procedure

In modes 1 and 2, the indicator erases truck ID numbers and tare weights from memory after the transaction. In modes 3–6,the truck ID and weigh-in weight values are saved after the weigh-out ticket has been processed.

The general weigh-in procedure is as follows:

1. The empty truck moves onto the scale for weigh-in.

2. Press the Weigh In softkey.

3. A prompt is shown to enter the truck ID (up to eight alphanumeric characters). Enter the ID, then press the

4. Indicator generates the weigh-in ticket:

ID 304812 GROSS 15000. LB INBOUND 01/14/2002 10:24 AM

enter key.

7.5 Single-Transaction Tare Weights and IDs

One-time transactions are supported in all modes that can be configured to use stored IDs (modes 3–6). This function allows one-time weighing of trucks without adding the truck ID and weigh-in weight to the permanent truck register.

To use this function, press the Weigh In or Weigh Out softkey, then enter a truck ID containing a decimal point. IDs entered with a decimal point as part of the ID are erased from the truck register when the transaction is complete.

5. Truck leaves the scale.

7.4 Weigh-Out Procedure

The general weigh-out procedure is as follows:

1. The loaded truck moves onto the scale for weigh-out.

2. If truck ID is known, press the Weigh Out softkey, enter the ID, and press the enter key.

If ID is not known, press the Tru c k Regs softkey to view list of stored IDs (see Figure 7-2 on page 63). Scroll to the correct truck ID, note the ID number, then press the

Cancel softkey to return to the weight display.

From the weight display, press in the ID, then press the

enter key.

3. Indicator generates the weigh-out ticket. In modes 1 and 2, the ID is deleted once the weigh-out ticket is processed.

8.0 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.

only.

8.1 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, you must activate the BATCHNG parameter on the SETPTS menu. This parameter defines whether a batch sequence is automatic or manual. AUTO sequences repeat continuously, while MANUAL sequences require a BATSTRT signal. The BATSTRT signal can be initiated by a digital input, serial command,

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.

NOTE: 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.

Batch Start softkey, or the StartBatch function in an iRite program.

NOTE: Weight-based setpoints are tripped by values specified in primary units

Kind Description Batch Continuous

OFF Setpoint turned off/ignored.

GROSS Gross setpoint. Performs functions based on the gross weight. The target

weight entered is considered a positive gross weight.

NET Net setpoint. Performs functions based on the net weight. The target weight

entered is considered a positive net weight value.

–GROSS Negative gross weight. Performs functions based on the gross weight. The

target weight entered is considered a negative gross weight.

–NET Negative net weight. Performs functions based on the net weight. The target

weight entered is considered a negative net weight value.

ACCUM Accumulate setpoint. Compares the value of the setpoint to the source scale

accumulator. The accumulator setpoint is satisfied when the value of the source scale accumulator meets the value and conditions of the accumulator setpoint.

ROC Rate-of-change setpoint. Performs functions based on the rate-of-change

(ROC) value.

+REL Positive relative setpoint. Performs functions based on a specified value above

a referenced setpoint, using the same weight mode as the referenced setpoint.

Table 8-1. Setpoint Kinds

X X

Setpoints 65

Page 72

Kind Description Batch Continuous

–REL Negative relative setpoint. Performs functions based on a specified value below

a referenced setpoint, using 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 Relative to a result setpoint. Performs functions based on a specified

percentage of the captured value of a referenced setpoint, using the same weight mode as the referenced setpoint. The actual target value of the RESREL setpoint is calculated as a percentage of the captured value of the referenced setpoint, rather than the target value.

PAU SE Pauses the batch sequence indefinitely. A BATSTRT signal must be initiated to

continue the batch process.

DELAY Delays the batch sequence for a specified time. The length of the delay (in

tenths of a second) is specified on the VALUE parameter.

WAITSS Wait for standstill. Suspends the batch sequence until the scale is at standstill. X

COUNTER Specifies the number of consecutive batch sequences to perform. Counter

setpoints should be placed at the beginning of a batch routine.

AUTOJOG Automatically checks the previous weight-based setpoint to verify the setpoint

weight value is satisfied in a standstill condition. If the previous setpoint is not satisfied when at standstill, the AUTOJOG setpoint activates the digital output of the previous weight-based setpoint for a period of time, specified on the VALUE parameter. The autojog process repeats until the previous weight-based setpoint is satisfied when the scale is at standstill.

NOTE: The AUTOJOG digital output is typically used to signify that an autojog operation is being performed. AUTOJOG 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. The 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. The 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. The 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. The digital output associated with this setpoint is

activated whenever a batch sequence is in progress. No value is required for this setpoint.

TIMER Tracks the progress of a batch sequence based on a timer.

X X

The timer value, specified in tenths of a second on the VALUE parameter, determines the length of time allowed between start and end setpoints. The indicator START and END parameters 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.

66 920i Installation Manual

Table 8-1. Setpoint Kinds (Continued)

Page 73

Kind Description Batch Continuous

CONCUR Allows a digital output to remain active over a specified portion of the batch

sequence. Two types of concur setpoints can be configured:

Type 1 (VA L U E = 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 tenths of a 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.

DIGIN Digital input setpoint. Requires a specific group of digital inputs to be in low (0

X X VDC) state to satisfy the setpoint. The digital output associated with this setpoint is held in a low (0 VDC) state until the inputs selected for the digital input mask are all in a low state.

AVG Average setpoint. Performs functions based on the calculated average weight

X over a specified number of A/D samples.

Note that this setpoint is based on the raw A/D weight value, rather than the rounded value shown on the indicator display. For example, if the display shows 50.0 but the actual raw A/D value is 49.99, the setpoint will not be satisfied.

TOD Time of day setpoint. Performs functions when the internal clock time of the

X X indicator matches the specified setpoint time.

DELTA Delta weight setpoint. Satisfied when the change in weight on the scale is equal

X to or exceeds the absolute value specified for the setpoint.

CHKWEI Checkweigher setpoint. Allows specification of over- and under-weight values.

Up to three digital outputs can be configured to represent overweight, underweight, and accept conditions.

PLSCNT Pulse counter setpoint. Performs functions based on pulse counts received by

X X a pulse input card.

PLSRAT Pulse rate setpoint. Performs functions based on the pulse rate received by a

pulse input card.

ALWAYS Always setpoint. This setpoint is always satisfied. It is typically used to provide

X an endpoint for true/false branching batch routines.

NEVER Never setpoint. This setpoint is never satisfied. It is used to branch to a

X designated setpoint in true/false branching batch routines in which the batch will not continue through the normal sequence of batch setpoints.

DINCNT Digital input count setpoint. Counts pulses received at the specified digital

X X input.

setpoint, once off, can trip on again.

Allows the digital output associated with a setpoint to shut off before the setpoint is satisfied to allow for material in suspension.

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

The LEARN value can be used to automatically adjust the preact value after each batch. LEARN compares the actual weight at standstill to the target setpoint value, then adjusts the preact PREVAL by the PREADJ value times the difference after each batch.

FLOW preact 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 preact uses the change in weight over time to anticipate when the TRIP minus PREACT weight value will be reached.

Depending on the TRIP setting specified for the setpoint, the setpoint trip value is adjusted up or down by the PREVAL value.

Preact adjustment factor. For setpoints with PREACT set to LEARN, specifies a decimal representation of the percentage of error correction applied (0.5 = 50%, 1.0 = 100%) each time a PREACT adjustment is made.

Preact stabilization time-out. For setpoints with PREACT set to LEARN, specifies the time, in 0.1-second intervals, to wait for standstill before 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.

Preact learn interval. For setpoints with PREACT set to LEARN, specifies the number of batches after which the preact value is recalculated. The default value, 1, recalculates the preact value after every batch cycle.

Warning

Batching Switch

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.

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 8-12. Each switch

uses a separate digital input.

When configuration is complete, exit setup mode. Initialize the batch by turning the 3-way switch to

ABORT, then unlock the STOP button (the STOP

button must be in the OUT position to allow the batch process to run). The batching switch is now ready to use.

If no digital input is assigned to BATRUN, batching proceeds as if

BATRUN were always on: the batch will start when the 3-way switch is turned to RUN, but the STOP mushroom button will not function.

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, do the following:

1. Unlock STOP button (OUT position)

2. Turn 3-way switch to START

To restart an interrupted batch from the first batch step, do the following:

1. Turn 3-way switch to ABORT

2. Unlock STOP button (OUT position)

3. Turn 3-way switch to START

NOTE: Use this procedure (or the BATRESET serial

command) to initialize the new batch routine following any change to the setpoint configuration.

8.4 Batching Examples

Example 1

The following example is used to dispense 100-LB drafts, automatically refilling a hopper to 1000 LB gross weight once the gross weight has dropped below 300 LB.

Setpoint 1 ensures that the hopper has enough material to start the batch. If the hopper weight is 100 LB or higher, setpoint 1 is tripped.

SETPOINT=1 KIND=GROSS VALUE=100 TRIP=HIGHER BATCH=ON ALARM=ON

Setpoint 2 waits for standstill, performs a tare, and puts the indicator into net mode.

SETPOINT=2 KIND=WAITSS PSHTARE=ON

Setpoint 3 is used as a reference (relative setpoint) for setpoint 4.

SETPOINT=3 KIND=NET VALUE=0 TRIP=HIGHER BATCH=OFF

Setpoint 4 is used to dispense material from the hopper. When the hopper weight goes below 100 LB net the setpoint is tripped.

SETPOINT=4 KIND=–REL VALUE=100 TRIP=LOW BATCH=ON DIGOUT=1 RELNUM=3

Setpoint 5 is used to evaluate the gross weight of material in the hopper after dispensing. When the hopper weight falls below 300 LB, digital output 2 becomes active and the hopper is refilled to 1000 LB.

SETPOINT=5 KIND=GROSS VALUE=300 TRIP=HIGHER HYSTER=700 BATCH=ON DIGOUT=2

Setpoint 6 is used as a “no flow alarm”. If the process in setpoint 4 is not completed in 10 seconds, digital output 4 becomes active to signify a problem.

SETPOINT=6 KIND=TIMER VALUE=100 START=4 END=5 DIGOUT=4

Example 2

The following example uses a CONCUR setpoint to provide a two-speed simultaneous fill of a hopper to a net weight of 1000 LB.

Setpoint 1 ensures that the gross weight is within 50 LB of gross zero.

SETPOINT=1 KIND=GROSS VALUE=0 TRIP=INBAND BANDVAL=50 BATCH=ON

Setpoint 2 performs a tare once the scale is at standstill.

SETPOINT=2 KIND=WAITSS PSHTARE=ON

82 920i Installation Manual

Page 89

Setpoint 3 uses DIGOUT 1 to fill a hopper to a net weight of 800 LB.

SETPOINT=3 KIND=NET VALUE=800 TRIP=HIGHER BATCH=ON DIGOUT=1

Setpoint 4 uses DIGOUT 2 to fill the hopper to a net weight of 1000 LB.

SETPOINT=4 KIND=NET VALUE=1000 TRIP=HIGHER BATCH=ON DIGOUT=2

Setpoint 5 operates DIGOUT 2 while Setpoint 3 is active, providing simultaneous two-speed filling.

9.0 Serial Commands

The 920i indicator can be controlled by a personal computer or remote keyboard connected to an indicator serial port. Control is provided by a set of serial commands that can simulate front panel key press functions, display and change setup parameters, and perform reporting functions. The serial commands provide the capability to print configuration data or to save that data to an attached personal computer. This section describes the serial command set and procedures for saving and transferring data using the serial ports.

9.1 The Serial Command Set

The serial command set can be divided into five groups: key press commands, reporting commands, the RESETCONFIGURATION special function command, parameter setting commands, and transmit weight data commands.

When the indicator processes a serial command, it responds with the message verifies that the command was received and has been executed. 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.

9.1.1 Key Press Commands

Key press serial commands (see Table 9-1) simulate pressing the keys on the front panel of the indicator. These commands can be used in both setup and normal (weighing) mode. Several of the commands serve as “pseudo” keys, providing functions that are not represented by a key on the front panel.

For example, to enter a 15-pound tare weight using serial commands:

1. Type K1 and press ENTER (or RETURN).

2. Type K5 and press ENTER.

3. Type KTARE and press ENTER.

NOTE: All load cell calibration settings are lost when the RESETCONFIGURATION command is run.

9.1.4 Parameter Setting Commands

Parameter setting commands allow you to display or change the current value for a particular configuration parameter (Tables

9-3 through 9-11).

Current configuration parameter settings can be displayed in either setup mode or normal mode using the following syntax:

command<ENTER>

Most parameter values can be changed in setup mode only; setpoint parameters listed in

Tabl e 9-6 on page 89 can be changed when in normal weighing mode.

Use the following command syntax when changing parameter values:

command=value<ENTER>, where value

is either a number or a parameter value. Use no spaces before or after the equal (=) sign. If you type an incorrect command, the display reads

??.

For example, to set the motion band parameter on Scale #1 to 5 divisions, type the following:

SC.MOTBAND#1=5D<ENTER>

Page 100

9.1.7 Database Commands

The commands listed in Table 9-13 can be used to create and maintain databases in the 920i. Except for

DB.DELALL command, all of the database

the commands require an extension to identify the number of the database within the memory card and the slot number of the memory card.

Command Description

DB.ALIAS.n#x Get or set database name

DB.CLEAR.n#x Clear database contents

DB.DATA.n#x Get or set database contents

DB.SCHEMA.n#x Get or set database structure

DB.DELALL Delete all databases and database

contents

n represents the database number within the memory card; x is the slot number of the memory card.

Each command must be terminated with a carriage return character (<CR>, ASCII 13).

Table 9-13. Database Commands

DB.ALIAS

The DB.ALIAS command is used to get or set the alias used by

iRite programs to reference the specified

database. Each database alias must be unique among all databases and adhere to the following rules: 8 character maximum; must begin with an alpha character or an underscore; can only contain A–Z, a–z, 0–9, or an underscore (_).

Example. The following command assigns an alias of

TRUCKS_2 to the first database on the memory card installed in slot 2:

DB.ALIAS.1#2=TRUCKS_2<CR>

Sending the DB.ALIAS command alone, without assigned data, returns the current database alias.

DB.CLEAR

To clear the contents of a database, send the following command:

DB.CLEAR.n#x<CR>

Where:

n is the database number within the memory card x is the slot number of the memory card (0 is the

onboard memory)

The 920i responds with OK<CR> if the command is successful,

DB.DATA

??<CR> if unsuccessful.

The DB.DATA command can be used to send data to or retrieve data from the

920i.

Data can be sent to the indicator using the following command:

DB.DATA.n#x = data{ | }<CR>

Where:

n is the database number within the memory card x is the slot number of the memory card (0 is the

onboard memory)

data represents a single cell of a row of data

{ | } is a pipe character (ASCII 124), used to

delimit cell data. If the data being sent is not the last cell of the row, append the pipe character to the data to indicate that more data is coming for that particular row. If the data being sent is the last cell of the row, do not append the pipe character.

If the command is accepted, the 920i responds with

OK<CR>; if not, it responds with ??<CR>.

Example. The following commands place the data

shown in

Table 9-14 into the first database in the

onboard memory:

DB.DATA.1#0=this|<CR> DB.DATA.1#0=is|<CR> DB.DATA.1#0=a|<CR> DB.DATA.1#0=test<CR>

DB.DATA.1#0=aaa|<CR> DB.DATA.1#0=bbb|<CR> DB.DATA.1#0=ccc|<CR> DB.DATA.1#0=ddd<CR>

Cell

Record

first this is a test

second aaa bbb ccc ddd

1 2 3 4

Table 9-14. Sample Database Contents

Sending the DB.DATA command alone, without assigned data, returns the database contents:

DB.DATA.n#x<CR>

The 920i responds with the entire contents of the database. Returned data is cell-delimited with the pipe character (ASCII 124) and row-delimited with carriage returns (ASCII 13).

For example, the following command could be used to return the contents of database 1 in the onboard memory:

DB.DATA.1#0<CR>
