A separate conduit system is recommended for installation. The type suggested for this application is 3/4" rigid

Note

steel conduit with pull boxes located at required intervals. The conduit provides additional noise protection for the low-level signals, while automatically complying with the requirements for two-inch separation between intrinsically safe circuits and other electrical cables. Conduit seals are necessary where a gas tight seal is required between hazardous area and safe area.

2.3.2 AC Power Wiring

Standard units are powered by an FM-approved power supply. 100–240 VAC into RLWS IS-EPS-100-240 Intrinsically safe DC output power supply (PN 72713) is recommended.

See the IS-EPS-100-240 Power Supply Instruction Sheet (PN 79820) for information on wiring and power specifications.

2.3.3 Battery Option

The optional battery pack provides an intrinsically safe battery that can replace the power supply. The battery is approved for use in hazardous environments and limited use operations such as bench scales and platform scales. A low battery error message will display to indicate that the battery needs to be recharged. Always charge the battery overnight. The yellow indicator light will remain on until the battery is charged at about 70%, at which point the indicator light will turn green and the charger will switch to float charge mode. Once the light turns green, the battery requires another 3 hours on float charge before the battery is fully charged.

To keep battery at full capacity, it is recommended to leave the battery connected to the charger, in float charge mode, until ready to use. The battery can remain on the charger in float charge mode indefinitely without damaging the battery. See Battery Charging Instruction Sheet (PN 96567) for instructions on charging the battery.

2.5 Fiber Optics Installation

The 320IS Plus is equipped with a duplex fiber optic port for communicating with an I/O Module located outside the hazardous area. This is the only communications channel of the indicator. The indicator communicates with external devices through the optional I/O Module’s physical interfaces (RS–232, RS–422, RS–485, Current Loop) and provides analog and digital I/O functions such as setpoint relays and analog outputs.

The fiber optics port is located on the indicator CPU board (see Figure 2-5).

2.5.1 Assembling Fiber Optics Connectors

Use the following steps for assembling the fiber optic connectors of the 320IS Plus:

1. Cut off the ends of the fiber optic cable (PN 74000) with a single-edge razor blade or hot knife (PN

85548). Try to obtain a precise 90º angle.

2. Insert the fiber through the locking nut and into the connector until the core tip seats against the internal micro-lens.

3. Screw the connector locking nut down to a snug fit, locking the fiber in place.

4. Secure fiber with 3-inch nylon cable ties in parts kit and 3/4-inch square nylon mounts.

Figure 2-7. Fiber Optics Connector

2.6 Enclosure Reassembly

1. Position the backplate over the enclosure.

2. Reinstall the backplate screws. Use the torque pattern shown in Figure 2-8 to prevent distorting the backplate gasket. Torque screws to 15 in-lb (1.7 N-m).

Torqued screws may become less tight as the gasket is compressed during torque pattern, therefore a second torque is required using the same pattern and torque value.

3.0 Configuration

Note

To configure the 320IS Plus indicator, the indicator must be placed in setup mode. The setup switch is accessed by removing the large fillister head screw on the enclosure backplate. Setup mode is enabled by inserting a non-metallic screwdriver into the access hole and pressing the pushbutton configuration switch.

SERIAL, PFORMT, SETPNT, DIGIN, and ALGOUT functions require fiber optics communications with I/O module in order to operate.

When the indicator is placed in setup mode, the word CONFIG is shown on the display. The CONFIG menu is the first of nine main menus used to configure the indicator. See complete, scroll to the CONFIG menu then press the (ZERO) key to exit setup mode. Replace the setup switch access screw.

3.1 Configuration Methods

The 320IS Plus indicator can be configured by:

• front panel keys (see section 3.2)

• sending commands or configuration data to the EDP port of the optional I/O Module

Configuration using the EDP port can be accomplished using either the EDP command set described in Section 5.0 on page 44 or the Revolution® configuration software.

3.1.1 Revolution Configuration

The Revolution configuration software is the preferred method for configuring the 320IS Plus indicator. Download Revolution on a computer to set the configuration parameters for the indicator. When Revolution configuration is complete, configuration data can be downloaded to the indicator through the optional I/O Module’s EDP port.

Revolution supports both uploading and downloading of indicator configuration data. This capability allows configuration data to be retrieved from one indicator, edited, then downloaded to another.

To use Revolution, do the following:

Section 3.2 on page 22. When configuration is

1. Install Revolution on a computer running Windows® 98 or later. Minimum system requirements are 32MB of system RAM (64MB for NT4/2000/XP) and at least 40MB of available hard disk space.

2. With both the I/O Module and indicator powered off, connect the PC serial port to the RS-232 pins on the I/O Module’s EDP port (See Section 8.0 on page 61 for terminal pin diagrams).

3. Power up the I/O Module and the indicator. Use the setup switch to place the indicator in setup mode.

4. Start the Revolution program.

Revolution provides online help for each of its configuration sections. Parameter descriptions provided in this manual for front panel configuration can also be used when configuring the indicator using Revolution: the interface is different, but the parameters are the same.

3.1.2 EDP Command Configuration

The EDP command set can be used to configure the 320IS Plus indicator using a personal computer, terminal, or remote keyboard. EDP command configuration sends commands to the indicator EDP port; commands can be sent using any external device capable of sending ASCII characters over a serial connection.

EDP commands duplicate the functions available using the indicator front panel and provide some functions not otherwise available. EDP commands can be used to simulate pressing front panel keys, to configure the indicator, or to dump lists of parameter settings. See command set.

3.1.3 Front Panel Configuration

The 320IS Plus indicator can be configured using a series of menus accessed through the indicator front panel when the indicator is in setup mode.

Table 3-1 summarizes the functions of each of the main menus.

Zero track band — Automatically zeroes the scale when within the range specified, as long as the input is within the configured zero range (ZRANGE parameter). Selections are ± display divisions. Maximum legal value varies depending on local regulations.

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

Motion band — Sets the level, in display divisions, at which scale motion is detected. If motion is not detected for one second or more, the standstill symbol lights. Some operations, including print, tare, and zero, require the scale to be at standstill. Maximum legal value varies depending on local regulations.

If OFF is selected, ZTRKBN should also be set to OFF.

Overload — Determines the point at which the display blanks and an out-of-range error message is displayed. Maximum legal value varies depending on local regulations.

Sample rate — Selects the analog to digital measurement rate of converted samples per second. Lower sample rate values provide greater signal noise immunity. If instability occurs, use lower sample rate to reduce signal noise.

Digital filtering — Selects the digital filtering rate used to reduce the effects of mechanical vibration from the immediate area of the scale. 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.

5.0 EDP Commands

Note

The 320IS Plus indicator can be controlled by a computer or remote keyboard connected to the I/O Module’s EDP port. Control is provided by a set of EDP commands that can simulate front panel key press functions, display and change setup parameters, and perform reporting functions. The EDP port provides the capability to print configuration data or to save that data to an attached computer. This section describes the EDP command set and procedures for saving and transferring data using the EDP port.

5.1 The EDP Command Set

The EDP command set 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 an EDP command, it responds with the message OK. The OK response 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.

5.1.1 Key Press Commands

Key press EDP commands (see Table 5-1) simulate pressing the keys on the front panel of the indicator. Most commands can be used in both setup and 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 EDP commands:

Scale must be at zero gross.

??.

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

2. Type K5 and press ENTER.

3. Type KTARE and press ENTER. The display shifts to net mode when the tare is entered.

Most parameter values can be changed in setup mode only. Use the following command syntax when changing parameter values:

command=value<ENTER>

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

??. Changes to the parameters are saved as they are entered but

typically do not take effect until you exit setup mode.

For example, to set the motion band parameter to 5, type the following:

5.1.6 Batching Control Commands

The commands listed below provide batching control through the EDP port.

BATSTART

If the BATRUN digital input is active (low) or not assigned, The BATSTART command can be used to start the batch program.

BATRESET

Stops the program and resets the batch program to the first batch step. Run the BATRESET command after making changes to the batch configuration.

BATPAUSE

Stops the batch program at the current step. All digital outputs set on by the current step are set off. The BATSTA DIGIN, BATSTART EDP command can be used to restart the batch program at the current step.

BATSTATUS

The BATSTATUS command is used to check the current status of various setpoint and batching conditions. BATSTATUS returns 14 bytes of status data as described in

Figure 5-15 on page 51. BATSTATUS is principally

used to provide status information to a controlling batch program when using the Remote I/O Interface option.

Status information returned in bytes 3 - 12 is coded as ASCII characters @ (hex 40) through 0 (hex 4F); only the low order bits of these characters are significant.

Table 5-15 on page 51 shows the low order bit assignments for

bytes 3 - 12. Use Tab le 5-16 on page 51 to interpret the status of the low order bits for a given ASCII character.

5.2 Saving and Transferring Data

Note

Saving and transferring data requires the use of an I/O Module.

Connecting a personal computer to the 320IS Plus EDP port allows you to save indicator configuration data to the PC or to download configuration data from the PC to an indicator. The following sections describe the procedures for these save and transfer operations.

Saving and transferring data requires the optional I/O module. See Section 9.0 on page 72 for more information on the I/O module.

5.2.1 Saving Indicator Data to a Personal Computer

Configuration data can be saved to a personal computer connected to the EDP port. The PC must be running a

communications program such as ProComm Plus (PN 78076) OR, Section 9.0 on page 72, for information about serial communications wiring and EDP port pin assignments.

When configuring the indicator, ensure that the values set for the BAUD and BITS parameters on the SERIAL menu match the baud rate, bits, and parity settings configured for the serial port on the PC. Set the PRNDES parameter to EDP.

To save all configuration data, place the indicator in setup mode and send the DUMPALL EDP command to the indicator. The

5.2.2 Downloading Configuration Data from PC to Indicator

320IS Plus responds by sending all configuration parameters to the PC as ASCII-formatted text.

Configuration data saved on a PC or floppy disk can be downloaded from the PC to an indicator. This procedure is useful when a number of indicators with similar configurations are set up or when an indicator is replaced.

To download configuration data, connect the PC to the EDP port as described in Section 5.2.1. Place the indicator in setup mode and use the PC communications software to send the saved configuration data to the indicator. When transfer is complete, calibrate the indicator as described in

Calibration settings are included in the configuration data downloaded to the indicator.

If the receiving indicator is a direct replacement for another 320IS Plus and the attached scale is not changed, recalibration is not required.

6.0 Print Formatting

The 320IS Plus provides four print formats, GFMT, NFMT, CFMT, and SPFMT that determine the format of the printed output when the entered or acquired, NFMT is used; otherwise, GFMT is used.

Each print format can be customized to include up to 300 characters of information, such as company name and address, on printed tickets. You can use the indicator front panel (PFORMT menu), EDP commands, or the

Revolution

configuration utility to customize the print formats.

6.1 Print Formatting Commands

Table 6-1 lists commands you can use to format the gross and net 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.

PRINT key is pressed or when a KPRINT EDP command is received. If a tare has been

Table 6-2. GFMT and NFMT Formats

The <G2>, <N2>, and <T2> commands listed in Ta bl e 6-1 print the gross, net, and tare weights in non-displayed units—that is, in the units not currently displayed on the indicator.

ID numbers included in the print format string (<UID> command) must be set using the UID=VAL EDP command.

The 300-character limit of each print format string includes the output field length of the print formatting commands, not the command length. For example, if the indicator is configured to show a decimal point, the <G> command generates an output field of 13 characters: the 10-character weight value (including decimal point), one space, and a two-digit units identifier.

6.2 Customizing Print Formats

The following sections describe procedures for customizing the GFMT, NFMT and formats using the EDP port, the front panel (PFORMT menu), and the Revolution® configuration utility.

6.2.1 Using the EDP Port

With a computer, terminal, or remote keyboard attached to the I/O Module EDP port, you can use the EDP command set to customize the print format strings.

To view the current setting of a format string, type the name of the string (GFMT, NFMT or SPFMT) and press

ENTER. For example, to check the current configuration of the GFMT format, type GFMT and press ENTER. The

indicator responds by sending the current configuration for the gross format:

GFMT=<G> GROSS<NL>

To change the format, use the GFMT, NFMT or SPFMT EDP 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 EDP command:

GFMT=FINE TRANSFER CO<NL>32400 WEST HIGHWAY ROAD<NL>SMALLTOWN<NL2><G> GROSS<NL>

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

FINE TRANSFER CO 32400 WEST HIGHWAY ROAD SMALLTOWN

If you have no access to equipment for communication through the EDP port or are working at a site where such equipment cannot be used, you can use the PFORMT menu (see

Figure 6-1 on page 55) to customize the print

formats.

Using the PFORMT menu, you can edit the print format strings by changing the decimal values of the ASCII characters in the format string.

Lowercase letters and some special characters cannot be displayed on the 320IS Plus front panel (see the ASCII character chart on Tab le 8-4 on page 64 and Tabl e 8-5 on page 65) and are shown as blanks. The

320IS Plus can send or receive any ASCII character; the character printed depends on the particular ASCII

character set implemented for the receiving device.

Figure 6-1. PFORMT Menu

6.2.3 Using Revolution®

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

The 320IS Plus indicator provides eight programmable setpoints for control of both indicator and external equipment functions.

Control of external equipment is available only if an I/O Module is connected to the 320IS Plus.

Setpoints are configured to trip based on specified conditions; tripping the setpoint can be used to request indicator functions (print, tare, accumulate) or to change the state of a digital output controlling external equipment.

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

Programmable setpoints require the optional I/O module. See Section 9.0 on page 72 for more information on the I/O module.

Figure 7-1 shows the general structure of the SETPTS menu. See Section 3.2.7 on page 32 for a detailed description of the SETPTS menu. The eighteen setpoint kinds are described in Table 7-1 on page 57.

7.1 Batch and Continuous Setpoints

320IS Plus setpoints can be either continuous or batch setpoints.

Continuous setpoints are free-running: the indicator constantly checks the input channel for the setpoint

value at each A/D update. If the input channel weight reading matches the setpoint value, the indicator sets the corresponding digital output on.

Batch setpoints are active one at a time, in an ordered sequence. The 320IS Plus can use batch setpoints to

control up to eight separate batch processing steps. A digital output associated with a batch setpoint is on until the setpoint condition is met, then latched for the remainder of the batch sequence.

56 320IS Plus Installation Manual

Figure 7-1. SETPTS Menu

Page 63

To use batch setpoints, you must activate the BATCHN 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 BATSTA digital input, BATSTART EDP command. As shown in

Table 7-1 on page 57, GROSSP, NETSP, and RELSP setpoint kinds can be configured as either batch or continuous setpoints. The BATCH parameter must also be set on for each batch setpoint. If the setpoint is defined but the BATCH parameter is off, the setpoint operates as a continuous setpoint, even during batch sequences.

Kind Description Batch Continuous

OFF Setpoint turned off/ignored. GROSSP Gross setpoint. Trips when the current gross weight matches this value.   NETSP Net setpoint. Trips when the current net weight matches this value.   +RELSP Positive relative setpoint. Trips at a specific value above the referenced setpoint.   –RELSP Negative relative setpoint. Trips at a specific value below the referenced

setpoint.

%RELSP Percent relative setpoint. Trips at a specific percentage 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. Operator must activate the BATSTA

digital input to continue processing.

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. Pauses the batch sequence until the scale is at standstill.  COUNTR Specifies the number of consecutive batch sequences to perform.  AUTJOG Automatically jogs the previous filling operation.  COZ Center of zero. The digital output associated with this setpoint is activated

when the scale is at center of zero. No value is required for this setpoint. NMOTON In motion. The digital output associated with this setpoint is activated when the

scale is not at standstill. No value is required for this setpoint. NRANGE In range. The digital output associated with this setpoint is activated when the

scale is within capacity range. No value is required for this setpoint. –GROSS Negative gross weight. The digital output associated with this setpoint is

activated when the gross weight reading is less than zero. No value is required

for this setpoint. –NET Negative net weight. The digital output associated with this setpoint is activated

when the net weight reading is less than zero. No value is required for this

setpoint. ACCUN 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. BATPRO 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.

Kind Description Batch Continuous

Note

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.

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.

Typ e 2 ( VAL U E > 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.

If more than one concurrent setpoint is configured, each must be assigned to a different digital output.

7.2 Batching Examples

This section contains two examples of batching routines using setpoints to change the state of a digital output controlling the external equipment.

7.2.1 Example 1

The following example uses seven setpoints to dispense material from a hopper in 100 LB batches and to automatically refill the hopper when its weight drops below 300

LB.

Digital inputs 1 and 2 are assigned to batch start and batch run functions: BATRUN must be on (low) before the BATSTA input starts the batch.

DIGIN1=BATSTA DIGIN2=BATRUN BATCHNG=MANUAL

Setpoint 1 ensures that the hopper has enough material to start the batch. If the hopper weight is 300 LB or higher, setpoint 1 is tripped.

SETPOINT=1 KIND=GROSSSP VALUE=300 TRIP=HIGHER BATCH=ON ALARM=ON

Setpoint 2 waits for standstill, then performs a tare to put 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=NETSP VALUE=0 TRIP=HIGHER BATCH=OFF

58 320IS Plus Installation Manual

Page 65

Setpoint 4 is used to dispense material from the hopper. When the hopper weight falls to 100 LB less than its

Note

weight at the relative setpoint (setpoint 3), digital output 1 is set off.

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

Setpoint 5 is used to evaluate the gross amount of material in the hopper after dispensing, and to maintain a minimum material level in the hopper. When the hopper weight falls below 300 active and the hopper is refilled to 1000

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

LB.

LB, digital output 2 becomes

Setpoint 6 is used to ensure that the operation performed in setpoint 4 is completed within 10 seconds. The START and END parameters identify the setpoints monitored by the timer. If the timer expires before setpoint 5 starts, digital output 4 is turned on as an alarm to signal a process fault.

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

Using the ACCESS Parameter

The ACCESS parameter should be set ON when creating and testing batch routines. Once the batching routine is complete and ready for production, ACCESS can be set to OFF to prevent changes to the configured setpoint value, or to HIDE to prevent changing or viewing the value.

Setpoints with ACCESS=ON can be turned ON or OFF and the setpoint value can be changed when a batch is not running by doing the following:

• To turn the setpoint off, use the SETPOINT key to access the setpoints and press the PRINT key until the desired setpoint is displayed. If the setpoint is on, the lb LED will be lit. Press the CLR key to turn the setpoint off

• To turn the setpoint on, use the SETPOINT key to access the setpoints and press the PRINT key until the desired setpoint is displayed. If the setpoint is of, the lb LED will not be lit. Press the

CLR key to turn the

setpoint on

• To change the value of a setpoint, press the SETPOINT key to access the setpoints, press the PRINT key until the desired setpoint is displayed. Press the GROSS/NET key twice. Enter the new value (including the decimal point) and press the TARE key. Press the

Setpoints cannot be turned on or off while in a batch sequence. A setpoint value cannot be changed while in a batch sequence.

Setpoint 4 starts the fast fill operation. When the net weight reaches 175 LB, the setpoint trips and digital output 1 is set off.

SETPOINT=4 KIND=NETSP VALUE=175 TRIP=HIGHER BATCH=ON DIGOUT=1

Setpoint 5 controls the slow fill operation. When the net weight reaches 200 LB, the slow fill is stopped (see Setpoint 7), the indicator waits for standstill and performs a push print operation using the SPFMT ticket format.

8.1 Error Messages

The 320IS Plus indicator provides a number of error messages. When an error occurs, the message is shown on the indicator LED display. Error conditions can also be checked remotely by using the XE EDP command as described in

8.1.1 Displayed Error Messages

The 320IS Plus provides a number of front panel error messages to assist in problem diagnosis. Tabl e 8-1 lists these messages and their meanings.

Table 8-1. 320IS Plus Error Messages

8.1.2 Using the XE EDP Command

The XE EDP command can be used to remotely query the 320IS Plus for the error conditions shown on the front panel. The XE command returns two 5-digit numbers in the format:

xxxxx yyyyy

where xxxxx contains a decimal representation of any existing error conditions as described in Tab le 8-2.

If more than one error condition exists, the number returned is the sum of the values representing the error conditions. For example, if the XE command returns the number 1040, this value represents the sum of an A/D reference error (1024) and an A/D calibration checksum error (16).

The second number returned (yyyyy) uses the same bit assignments as shown in Table 8-2 to indicate whether the test for the error condition was run. For example, the value yyyyy = 63487 represents the decimal equivalent of the binary value 1111 0111 1111 1111. Using the bit assignments in

Table 8-2, this value indicates all tests were run.

8.2 Status Messages

Two EDP commands, P and ZZ, can be used to provide status about the indicator. These commands are described in the following sections.

8.2.1 Using the P EDP Command

The P EDP command returns the current displayed weight value to the EDP port, along with the units identifier. If the indicator is in an underrange or overload condition, the weight value is replaced with ^^^^^^ (overload) or

_ _ _ _ _ _(under range).

The ZZ EDP command can be used to remotely query which annunciators are currently displayed on the indicator front panel. The ZZ command returns the currently displayed weight and a decimal number representing the LED annunciators currently lit. The format of the returned data is:

wwwwww uu zzz

where wwwwww uu is the current displayed weight and units, zzz is the annunciator status value (see Table 8-3). If more than one annunciator is lit, the second number returned is the sum of the values representing the active annunciators.

For example, if the annunciator status value returned on the ZZ command is 148, the gross, standstill, and lb annunciators are lit: 148 represents the sum of the values for the standstill annunciator (16), gross mode annunciator (128), and the lb/primary units annunciator (4).

8.5 Conversion Factors for Secondary Units

The 320IS Plus has the capability to mathematically convert a weight into many different types of units and instantly display those results with a press of the

Secondary units can be specified on the FORMAT menu using the SECNDR parameter, or by using EDP commands.

• SEC.MULT only applies if UNITS parameter (SECNDR) is set to NONE.

• To configure secondary units using the front panel, use Table 8-6 to find the conversion multiplier for the MULT parameter. For example, if the primary unit is pounds and the secondary unit is short tons, set the MULT parameter to 0.000500.

UNITS key.

320IS Plus Installation Manual - Appendix A 65

Page 72

You must use the MULT parameter to set the decimal point position. Use the numeric keypad or the

Note

LEFT/RIGHT keys to select the digit; Use the UP/DOWN keys to increment and decrement (see Figure 3-4

on page 16). LEFT/RIGHT keys also select decimal placement.

• To configure secondary units using EDP commands, use Ta ble 8-6 to find the conversion multiplier for the SEC.MULT command. For example, if the primary unit is pounds and the secondary unit is short tons, send the EDP command SEC.MULT= 0.0005<CR> to set the multiplier for the secondary units.

• Long tons and grains units listed in Table 8-6 cannot be directly specified as primary or secondary units on the 320IS Plus indicator. For these or other unlisted units of weight, specify NONE on the UNITS parameter.

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

For example, if the primary units are short tons, secondary units are pounds, and the secondary decimal point is set to

8888.88, the indicator will overflow if 5 tons or more are applied to the scale. With 5 tons applied, and a conversion factor of 2000, the secondary units display needs five digits to the left of the decimal point to display the 10000 lb secondary units value.

The 320IS Plus uses RATTLETRAPTM digital filtering to reduce the effect of vibration on weight readings. Adjustable threshold and sensitivity functions allow quick settling by suspending filter averaging, allowing the weight reading to jump to the new value.

Figure 8-2. Digital Filtering Parameters on the Configuration (CONFIG) Menu

8.6.1 DFSENS and DFTHRH Parameters

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

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

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

Figure 8-2 shows the digital filter parameters on the CONFIG menu.

8.6.2 Setting the Digital Filter Parameters

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

1. In setup mode, set the digital filter to 1. Set DFTHRH to NONE. Return indicator to normal mode.

2. Remove all weight from the scale, then watch the indicator display to determine the magnitude of vibration effects on the scale. Record the weight below which all but a few readings fall. This value is used to calculate the DFTHRH parameter value in Step 4.

For example, if a heavy-capacity scale produces vibration-related readings of up to 50 lb, with occasional spikes to 75 lb, record 50 lb as the threshold weight value.

3. Place the indicator in setup mode and set the digital filter (DIGFLT) to eliminate the vibration effects on the scale. (Leave DFTHRH set to NONE.) Reconfigure as necessary to find the lowest effective value for the digital filter.

4. Calculate the DFTHRH parameter value by converting the weight value recorded in Step 2 to display divisions: threshold_weight_value / DSPDIV.

In the example in Step 2, with a threshold weight value of 50 lb and a display division value of 5D: 50 /

5D = 10, the DFTHRH should be set to 10DD. See Figure 3-2 on page 25 for more information on

display divisions.

5. Finally, set the DFSENS parameter high enough to ignore transient peaks. Longer transients (typically caused by lower vibration frequencies) cause more consecutive out-of-band readings, so DFSENS should be set higher to counter low frequency transients.

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

9.4 Fiber Optics Assembly

The I/O Module is equipped with duplex fiber optic ports for communicating with other devices located in the safe or hazardous area. It provides electrical isolation and eliminates the use of I/O barriers commonly used in intrinsically safe systems. The fiber optic wires are plastic; no polishing or further preparation is required. See Figure 9-1 on page 73 for the location of the fiber optic ports on the I/O Module main board.

The fiber optic connections between the indicator and the I/O Module need to be cross-linked.

The optical output of the indicator should be attached to the input of the I/O Module, and the indicator’s input to the module’s output.

Use the following steps for assembling the fiber optics connectors of the I/O Module:

1. Cut off the ends of the fiber optic cable with a single-edge razor blade or sharp knife. Try to obtain a precise 90º angle.

320IS Plus Installation Manual - Appendix B 75

Page 82

2. Insert the fiber through the locking nut and into the connector until the core tip seats against the internal

micro-lens.

3. Screw the connector locking nut down to a snug fit, locking the fiber in place.

4. Secure duplex fiber optic cable to wire tie mounting button located on I/O Module circuit board (see Figure 9-1 on page 73) using wire ties included in parts kit.

Figure 9-4. Fiber Optics Connector

9.5 Analog Outputs

The I/O Module uses two 16-bit isolated analog output channels with 4-20mA and voltage (0-5V/±5V/0-10V/ ±10V) outputs supplied from a DC/DC converter. The output voltage ranges are DIP-switch selectable (see Figure 9-1 on page 73). Analog output configuration is done via setup mode in the indicator used with the I/O

Module (see the applicable indicator installation manual).

The analog output circuitry consists of two identical channels that can be assigned to gross or net weight values. The analog outputs can be configured to operate as either current or voltage outputs. The voltage output range is selected by configuring DIP switches SW1 (1-6) for channel 1 and SW2 (1-6) for channel 2 (see page 73).

10 Low DGND

Table 9-9. CN4 Connections

The digital inputs are designed to receive 0-24V/TTL signals on the incoming lines. Care should be taken to apply the right DC polarity. Pins 9 and 10 (+5V and DGND) can be used to supply power to the digital inputs. Maximum current draw should not exceed 0.25A.

See the applicable indicator installation manual for information on checking current digital input states.

9.7 Relay Contact Outputs

The I/O Module features four relay contact outputs, which default to open. This allows switching of maximum +30VDC, 5A or 250VAC, 5A for each of the four digital channels.

The relay contact outputs are controlled by user-configurable setpoints. The setpoint values and operating parameters can be defined in the SETPNT menu of the host indicator. See the indicator installation manual for information on configuring setpoints.
