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 desktop and universal models are included for the service technician. See Section 10.11 on page 108 for dimension drawings of the all models.

Caution

• 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 12 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

Warning

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

Desktop and universal models of the 920i provide six cord grips for cabling into the indicator: one for the power cord, Þve to accommodate cabling for option cards. Install plugs in all unused cord grips to prevent moisture from entering the enclosure.

opening the unit, ensure the power cord is disconnected from the power outlet.

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 Figure 2-1). 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 Figure 2-1).

3.0 Conﬁguration

To conÞgure the 920i indicator, the indicator must be placed in setup mode. The setup switch is accessed by removing the large Þllister head screw on the desktop and universal 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 Þrst used to conÞgure the indicator. Detailed descriptions of these menus are provided in Section 3.2.

When conÞguration is complete, press the

Save and Exit softkey to exit setup mode, then replace

Exit or

the setup switch access screw.

¥ The

Exit softkey exits setup mode without

saving parameter changes to NV RAM. Changes made to the conÞguration remain in the system until indicator power is cycled.

Save and Exit writes all parameter changes to

NV RAM before returning to normal mode.

3.1 Conﬁguration Methods

The 920i indicator can be conÞgured by using the front panel keys to navigate through a series of conÞguration menus or by sending commands or conÞguration data to an indicator serial port. ConÞguration using the menus is described in Section 3.1.3.

ConÞguration using the serial port can be accomplished using either the serial command set described in Section 9.0 or the utility.

NOTE: Some conÞguration parameters, such as those

used to conÞgure the

920i display and widgets, cannot

be accessed through the conÞguration menus. provides the most complete and efÞcient conÞguration interface for the

3.1.2 Serial Command Conﬁguration

The serial command set can be used to conÞgure the

920i indicator using either a personal computer,

terminal, or remote keyboard. Like

iRev, serial

command conÞguration 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 conÞgure the indicator, or to dump lists of parameter settings. See Section 9.0 on page 78 for more information about using the serial command set.

Speciﬁes the number of full scale graduations. The value entered must be in the range 1–9999999 and should be consistent with legal

requirements and environmental limits on system resolution. To calculate GRADS, use the formula, GRADS = Capacity / Display Divisions. Display divisions for primary and secondary units are speciﬁed under the FORMAT

submenu. See Level 4 submenu descriptions in Table 3-3 on page 26.

Automatically zeroes the scale when within the range speciﬁed, as long as the input is within the ZRANGE and scale is at standstill. Selections are ± display divisions. Maximum legal value varies depending on local regulations.

Selects the range within which the scale can be zeroed. The 1.9% selection is ± 1.9% around the calibrated zero point, for a total range of 3.8%. Indicator must be at standstill to zero the scale. Use 1.9% for legal-for-trade applications.

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

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.

Speciﬁes the minimum number of grads required for a weighment to be added to the recorded number of weighments.

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.

See Section 10.9 on page 106 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.

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 106 for more information about digital ﬁltering.

Enables RATTLETRAP 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.

In DELAY mode, the indicator performs a power up display test, then enters a 30-second warm up period. If no motion is detected during the warm up period, the indicator becomes operational when the warm up period ends; if motion is detected, the delay timer is reset and the warm up period repeated.

Enables or disables push-button and keyed tares. Possible values are:

BOTH: Both push-button and keyed tares are enabled NOTARE: No tare allowed (gross mode only) PBTARE: Push-button tares enabled KEYED: Keyed tare enabled

Parameter Choices Description

MULT 1.0

0.000001– 9999999

Multiplier. Speciﬁes the conversion factor by which the primary units are multiplied by to obtain the displayed rate of change units.

To calculate the MULT value, use the following equation: MUL T = (SMPRAT / INTERVL) * (seconds_per_ROC_unit) * (ROC/PRIMAR_precision_adjustment) Where:

• SMPRAT is the value speciﬁed for the A/D sample rate on the SCALES menu

• INTERVL is the speciﬁed ROC interval

• seconds_per_ROC_unit is an adjustment for the ROC UNITS parameter. If ROC UNITS is set to SEC, use 1; use 60 for UNITS=MIN, use 3600 for UNITS=HOUR.

• ROC/PRIMAR_precision_adjustment compensates for any difference in the DECPNT and DSPDIV parameters speciﬁed for primary units and ROC units. For example, if the ROC DECPNT parameter is set to 8888888 (no decimal) and with DSPDIV=1, ROC precision is 1. If PRIMAR DECPNT is set to 8888880 (null units position) and DSPDIV=2, PRIMAR precision is 20. (That is, weights will be displayed in increments of

20.) In this example, the precision adjustment would be 1 / 20, or 0.05.

Example: If SMPRAT=120HZ, INTERVL=240, ROC UNITS=MIN, and the precision is compensated as described above, MULT would be calculated as follows:

MULT = (120 / 240) * 60 * 0.05 = 1.5

To calculate a ROC MULT value based on secondary or tertiary units, multiply the calculated primary units MULT value by the conversion factor for the alternate units. For example, if a MULT value of 1.5 is calculated for pounds as the primary unit, calculate the MULT value for kilogram secondary units by multiplying the original MULT value by 0.453592:

MULT(kg) = 1.5 * 0.453592 = 0.680388

Update interval. Speciﬁes the number of A/D updates over which the rate-of-change is calculated.

Refresh interval. Speciﬁes the number of A/D updates between rate-of-change samples. The value speciﬁed for this parameter should be an integer not less than 1% and not more than 50% of the update interval (INTERVL parameter) speciﬁed. For example, if the INTERVL parameter value is 120, the REFRESH speciﬁed should be in the range of 2–60.

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 Þve-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 Installation Manual, PN 77224, for information about conÞguring 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 3-9 on page 34).

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, see Figure 4-2) is used to calibrate the span, and linear calibration point displays provide a set of softkeys used speciÞcally for calibration procedures:

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

1. Place the indicator in setup mode (display

CONFIG) and remove all weight from

reads the scale platform. If your test weights require hooks or chains, place the hooks or chains on the scale for zero calibration.

2. Send the 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 Þve linearization points can be calibrated between the zero and span calibration values.

Calibration 47

Page 52

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.

7. Send the KSAVE serial command to save the calibration changes; send KEXIT to exit setup mode.

6.0 Print Formatting

The 920i provides seven 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, and AUXFMT. 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 conÞguration (see Table 6-2 on page 55) 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. You can use the

(PFORMT menu) to customize the print formats.

6.1 Print Formatting Commands

Table 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.

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.

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 Table 6-1 on page 53 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 example, to check the current conÞguration of the GFMT format, type GFMT.FMT and press

enter key. For

enter. The

indicator responds by sending the current conÞguration 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 modiÞed 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>

Stored IDs let you keep a database of truck IDs and

Swapping

weigh-in weights in the indicatorÕs 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, itÕs 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, donÕt 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

conÞgure the

right to the SOFTKEYS submenu and

Weigh In, Weigh Out, and Truck Regs

softkeys. These keys are required when using the

truck modes.

The truck register can be printed to an attached printer by pressing the

PRINT key while the Truck Regs

display is shown. The printed register uses the TRFMT print format (see Section 6.2 on page 55).

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.

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 3Ð6,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

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 softkey, enter the ID, and press the enter key.

If ID is not known, press the softkey to view list of stored IDs (see Figure 7-2 on page 58). Scroll to the correct truck ID, note the ID number, then press the

Cancel softkey to return to the weight display.

8.0 Setpoints

The 920i indicator provides 100 conÞgurable setpoints for control of both indicator and external equipment functions. Setpoints can be conÞgured to perform actions or functions based on speciÞed parameter conditions. Parameters associated with various setpoint kinds can, for example, be conÞgured 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 speciÞed 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 deÞned 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

deÞnes 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 deÞned 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 speciÞed 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 sour ce 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

60 920i Installation Manual

ÖÖ

Page 65

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.

PAUSE 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. Ö 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.

ÖÖ

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.

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.

Table 8-1. Setpoint Kinds (Continued)

Setpoints 61

Page 66

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 (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 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

ÖÖ

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

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

ÖÖ

indicator matches the speciﬁed setpoint time.

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

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

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

an endpoint for true/false branching batch routines.

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

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

Speciﬁes whether the setpoint is satisﬁed when the weight is higher or lower than the setpoint value, within a band established around the value, or outside of that band.

band width. The band established around the setpoint value is VALUE ±BANDVAL.

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. 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 by half of the difference after each batch.

FLOW preact provides 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 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 preact value.

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

Time-out for preact learn. For setpoints with PREACT set to LEARN or FLOW, 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 or FLOW, speciﬁes the number of batches after which the preact value is recalculated. The default value, 1, recalculates the preact value after every batch cycle.

Tolerance band. For setpoints with TRIP set to HIGHER or LOWER, speciﬁes a tolerance band around the target weight. If the captured 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, below) until restarted or reset.

8.4 Batching Examples

Example 1

The following example is used to dispense 100-LB drafts, automatically reÞlling 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 reÞlled to 1000 LB.

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

Setpoint 6 is used as a Òno ßow alarmÓ. 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 Þll 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

76 920i Installation Manual

Page 81

Setpoint 3 uses DIGOUT 1 to Þll 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 Þll 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 Þlling.

SETPOINT=5 KIND=CONCUR VALUE=0 TRIP=HIGHER START=4 END=5 DIGOUT=2

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 conÞguration 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 Þve 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 veriÞes 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 ÒpseudoÓ 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

2. Type K5 and press

3. Type KTARE and press

Command Function

KBASE Select current scale (Example: KBASE,

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 conÞguration parameter (Tables 9-3 through 9-11).

Current conÞguration 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 Table 9-6 on page 83 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>

For parameters with selectable values, enter the command and equal sign followed by a question

command=?<ENTER> to see a list of those values.

mark: The indicator must be in setup mode to use this function.

NOTE: Some parameters are valid only if other

parameters or parameter values are speciﬁed. See the conﬁguration menus in Section 3.2 on page 21 for information about parameter dependencies. Restrictions for front-panel conﬁguration also apply to serial command conﬁguration.

BATRESET

Stops the program and resets the batch program to the Þrst batch step. Run the BATRESET command after making changes to the batch conÞguration.

9.1.7 Database Commands

The commands listed in Table 9-12 can be used to create and maintain databases in the

DB.DELALL command, all of the database

the

920i. Except for

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 9-12. Database Commands

DB.ALIAS

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

iRite programs to reference the speciÞed

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 AÐZ, aÐz, 0Ð9, or an underscore (_).

Example. The following command assigns an alias of

TRUCKS_2 to the Þrst 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)

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

The 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

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

Table 9-13. 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>

If the database contents are the records shown in Table 9-13, the indicator responds with the following data, using pipe characters and carriage returns to delimit the database cells and rows, respectively:

this|is|a|test<CR>aaa|bbb|ccc|ddd<CR>

You should determine the number of records currently in the database both prior to and after sending the

DB.DATA command to verify that the correct number of

records are received. The number of records can be determined with the

DB.SCHEMA command.

The 920i responds to the command above by returning the following:

The <Column Name>, <Data Type>, and <Data Size> elements repeat for each column in the database.

<Column Name> follows the rules for alias

The names: 8 character maximum; must begin with an alpha character or an underscore; can only contain AÐZ, aÐz, 0Ð9, or an underscore (_).

<Data Type> is represented by a numeric Þeld:

the programming. Up to ten different screens can be conÞgured.

Serial command widget programming is accomplished in setup mode, using the WDGT serial command. The Þrst parameter speciÞed is the widget type, listed in Table 9-16. The following sections describe each of the widget types and the parameters and values speciÞc to that type.

In setup mode, the WDGT.CLR serial command can be used to clear all speciÞed widgets from the display.

Type Description

1 Scale Widget 2 Bitmap Widget 3 Bargraph Widget 4 Label Widget 5 Numeric Widget 6 Symbol Widget

Some widget types require that the location or size of the widget be speciÞed, in pixels. Figure 9-16 shows the pixel counts (80 pixels per inch) used to specify the pixel location on the display.

9.2.1 Scale Widgets

Scale widgets are used to present basic scale data from one or more conÞgured scales. For multiple scale applications, up to four scale widgets can be conÞgured to be shown on the display at any one time. Fewer displayed widgets allow each widget to be larger. Scale data from additional conÞgured scales can be shown by scrolling up or down through all conÞgured scales, including a total scale widget, if conÞgured.

10.1.1 Option Card Diagnostic Errors

Option cards are detected by the 920i at power-up. If the current indicator conÞguration requires an option card but that card is not detected at power-up, an error similar to the following is displayed:

HARDWARE CRITICAL TO PROPER OPERATION

WITH CURRENT CONFIGURATION

CANNOT BE FOUND

A/D SLOT 4 CHANNEL 1

INSTALL HARDWARE OR RECONFIGURE

To recover from this error you can do the following:

¥ If the option is required, ensure that the card is

properly seated in its slot and cycle the power. If the card is still not recognized, replace the card or try installing the card in a different slot.

¥ Enter setup mode and reconÞgure to eliminate

the requirement for the option.

¥ Go to the VERSION menu and use the

Conﬁg softkey (or RESETCONFIGURATION

Reset

command) to perform a conÞguration reset. ConÞguration reset returns all conÞguration values to their factory defaults.

See Section 10.1.2 below, for information about using the HARDWARE serial command to verify that installed cards are recognized.

10.1.2 Using the HARDWARE Command

The HARDWARE serial command can be issued to verify that all installed cards are recognized by the system. The HARDWARE command returns a string of card type codes, representing cards installed in slots 1Ð14:

HARDWARE=3,3,2,4,5,0,0,0,0,0,0,0,0,0

Table 10-2 lists the card codes returned by the HARDWARE command.

10.1.4 Using the XE Serial Command

The XE serial command can be used to remotely query the 920i for the error conditions shown on the front panel. The XE command returns a decimal number representing any existing error conditions. For multi-scale applications, the value returned by the XE command represents all error conditions, if any, present on all conÞgured scales.

If more than one error condition exists, the number returned is the sum of the values representing the error conditions (see Table 10-3 on page 95).
