1.3 Factory Mutual Approval

The 320IS is Factory Mutual (FM) Entity approved for:
•Classes I, II, and III
•Divisions 1 and 2
•Groups A, B, C, D, E, F and G
•T-rating T4
Only devices that have FM Entity Appr oval with proper entity parameters may be used unless specifically listed in this manual or control drawing PN 72717 as part of the Rice Lake Factory Mutual systems approval. Failure to comply with this voids the FM approval.
The classification of hazardous materials are different in the US and European standards. Because of this, the safety class of the 320IS is declared in the US standards: Class I, II, III, DIV1, Groups A-G.
Substitution of components may impair intrinsic safety.
To prevent ignition of flammable or combustible atmospheres, disconnect power before servicing.

1.4 Operating Modes

The 320IS has three modes of operation.
Normal (Primary) Mode
Normal mode is the default mode of the indicator . Th e indicator displays gro ss or net weights as indi cated by LED annunciators (see Figure 1-1) to indicate scale status and the type of weight value displayed.
Setup Mode
Most of the procedures described in this manual require the indicator to be in setup mode including configuration and calibration.
To enter setup mode, remove the large fillister head screw from the enclosure backplate. Insert a small non­conductive tool into the access hole and press the setup switch once. The indicator displays
Test Mode
T est mode provides a number of diagnostic functions for the 320IS indicator. Like setup mode, test mode is entered using the setup switch (Section 7.8 on page 51).

The 320IS display uses a set of eight LED annunciators to provide additional information about the value being displayed (see Figure 1-1 on page 3):
LED Annunciators
Gross
Net

Count The Count annunciator is lit to show that the indicator is in piece count mode.

lb lb/kg – indicate the units associated with displayed value: lb=pounds, kg=kilograms. Two units of
kg
Table 1-3 shows which annunciators are used for all combinations of configured primary and secondary units. For example:
•If the primary unit is pounds (lb) and the secondary unit is kilograms (kg), the
kg for secondary units.
•If the primary unit is pounds (lb) and the secondary unit is short tons (tn), the
kg for secondary units. There is no LED for short tons, so the kg LED is used as the secondary units
annunciator.
•If the primary unit is short tons (tn) and the secondary unit is pounds (lb), the (tn), and kg is lit for secondary units (lb). Because there is no LED for short tons, the lb and kg LEDs are used as primary and secondary units annunciators.
See Section 3.3.2 on page 22 for more information about configuring primary and secondary display units.
Gross/Net – indicates whether the displayed weight is a gross or net weight
Center of Zero – gross weight is ±0.25 graduations of zero, lights when the scale is zeroed
Standstill – scale is at standstill or within the specified motion band, tare functions and printing, can only be done when the standstill symbol is lit
Tare Acquired – indicates that a tare value has been entered
measurement can be chosen to toggle between. The displayed units can also be set to ounces (oz), short tons (tn), metric tons (t), grams (g), or they can be disabled. A user-defined unit can also be set as secondary unit by declaring a conversion factor in the setup menu. The lb and kg LED’s function as primary and secondary units annunciators for some combinations of primary and secondary units. If neither primary nor secondary units are lb, kg, oz, or g, the lb annunciator is lit for primary units, kg for secondary units.

This section describes installation of load cells, power supply, fiber optics, and ferrite bead for the 320IS indicator.
Use a wrist strap to ground yourself and protect components from electrostatic discharge (ESD) when working inside the indicator enclosure.
It is mandatory to return the 320IS to Rice Lake Weighing Systems for circuit board level service. Component level repair, excluding board-swapping, is not permitted on Factory Mutual Approved equipment by anyone other than the manufacturer.

2.1 Unpacking and Assembly

Immediately after unpacking, visually inspect the 320IS to ensure all components are included and undamaged. The shipping carton should contain the indicator with attached tilt stand, this manual, and a parts kit. If any parts are missing or were damaged in shipment, notify Rice Lake Weighing Systems and the shipper immediately. See Table 2-5 on page 15 for parts kit.

2.2 Enclosure Disassembly

The indicator enclosure must be opened to connect cables for load cells, communications, and power.
Before opening the unit, ensure the power is disconnected from the power outlet.

1. Place the indicator face-down on an anti-static work mat.

2. Remove the screws that hold the backplate to the enclosure body.

3. Lift the backplate away from the enclosure and set it aside.

2.3 Hazardous Area Installation of the 320IS

The following information is provided to help the installer with the correct installation of the 320IS system. See Figure 2-1 below for a diagram of a typical intrinsically safe system.

2.3.1 Power Supply to Indicator

WARNING
Note
Note
Do not, under any circumstances, connect or disconnect the DC wire from the indicator while the AC power is applied to the power supply. This will cause the power supply fuse to blow.
The indicator should be powered by an FM-approved Rice Lake power supply or alternatively from an external battery pack. The power requirements of the 320IS are as follows:
•Minimum input voltage: 5.8 V
•Maximum input voltage: 7.9 V
•Peak current consumption: 190 mA
•Average input current (with four load cells): 140 mA
The DC power cable should be attached to connector CN1. Care must be taken to wire CN1 with the correct DC polarity. See Section 2.4 on page 9 for information on cabling through metal cord grips.
CN1 Pin Function Wire Color

1 + Voltage (5.8 – 7.9 V) Green 2 Ground (V–, Common) Brown

Table 2-1. DC Power Supply Connections

A separate conduit system is recommended for installation. The type suggested for this application is 3/4" rigid 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 F.M. approved power supply. We recommend the 100–240 VAC into RLWS IS­EPS-100-240 Intrinsically safe DC output power supply (PN 72713).
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 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:
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'' nylon cable ties in parts kit and 3/4'' square nylon mounts.

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 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, 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 Section 3.3 on page 19. When configuration is complete, scroll to the CONFIG menu then press the ( access screw.

3.1 Configuration Methods

The 320IS indicator can be configured by using the front panel keys to navigate through a series of configuration menus or by sending commands or configuration data to the EDP port of the optional I/O Module. Configuration using the menus is described in Section 3.3 on page 19.
Configuration using the EDP port can be accomplished using either the EDP command set described in Section 5.0 on page 33 o r Version 3.1 or later of the Revolution

3.2 Configuration Methods

The 320IS indicator can be configured by:
front panel keys
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.
ZERO) key to exit setup mode. Replace the setup switch
®
configuration software.

3.2.1 Revolution Configuration

The Revolution configuration software is the preferred method for configuring the 320IS 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:
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 53 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.

3.2.2 EDP Command Configuration

The EDP command set can be used to configure the 320IS 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 Section 5.0 on page 44 for more information about using the EDP command set.
18 320IS Installation Manual
Page 23

3.2.3 Front Panel Configuration

The 320IS indicator can be configured using a series of menus accessed through the indicator front panel when the indicator is in setup mode. Table 3-1 summarizes the functions of each of the main menus.
Menu Menu Function
CONFIG Configuration Configure grads, zero tracking, zero range, motion band, overload, tare function, push button
enable, and digital filtering parameters. FORMAT Format Set format of primary and secondary units, display rate. CALIBR Calibration Calibrate indicator. See Section 4.0 on page 31 for calibration procedures. SERIAL Serial Configure EDP and printer serial ports. PROGRM Program Set regulatory mode, unit ID, auto zero, consecutive number values, and battery standby. PFORMT Print Format Set print format used for gross and net tickets. See Section 6.0 on page 39 for more information. DIGIN Digital Input Assign digital input functions. See Section Figure 3-7. on page 28 for more information. ALGOUT Analog Output Configure analog output. See Section 3.3.7 on page 29 for analog output configuration. VERS Version Display installed software version number.
Table 3-1. 320IS Menu Summary

3.3 Menu Structures and Parameter Descriptions

The following sections provide graphic representations of the 320IS menu structures. In the actual menu structure, the settings you choose under each parameter are arranged horizontally. To save page space, menu choices are shown in vertical columns. The factory default setting appears at the top of each column.
Most menu diagrams are accompanied by a table that describes all parameters and parameter values associated with that menu. Default parameter values are shown in bold type.
To exit configuration mode, with the display showing

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.

Power up mode. In GO mode, the indicator goes into operation immediately after a brief power up display test.
In DELAY mode, the indicator performs a power up display test, then enters a 30–second warm up period. If no motion is detected during the warm up period, the indicator becomes operational when the warm up period ends; if motion is detected, the delay timer is reset and the warm up period is repeated.
Specifies whether operator has access to piece count mode and the default sample size used for parts counting. See Level three submenu for parameter descriptions.
Regulatory mode. Specifies the regulatory agency having jurisdiction over the scale site. OIML, NTEP, and CANADA modes allow a tare to be acquired at any weight greater than zero.
NONE allows tares to be acquired at any weight value. OIML, NTEP, and CANADA modes allow a tare to be cleared only if the gross weight is at no
load. NONE allows tares to be cleared at any weight value. NTEP and OIML modes allow a new tare to be acquired even if a tare is already present. In
CANADA mode, the previous tare must be cleared before a new tare can be acquired. NONE, NTEP and CANADA modes allow the scale to be zeroed in either gross or net mode as
long as the current weight is within the specified ZRANGE. In OIML mode, the scale must be in gross mode before it can be zeroed; pressing the ZERO key in net mode clears the tare.
Consecutive numbering. Allows sequential numbering for print operations. The consecutive number value is incremented following each print operation.
The initial value of this parameter is set to the start up value specified on the CONSTU parameter. Changing either CONSTU or CONSNU immediately resets the consecutive number used for printing.
Consecutive number start up value in the range of 000000–999999. Specifies the initial consecutive number (CONSNU) value used when the indicator is powered on.

Allows selection of date format and date separator. See level three parameter for descriptions.
Allows selection of time format and time separator. See level three parameter for descriptions.
Standby mode delay. Specifies the number of minutes the indicator must be inactive before entering standby mode. Valid values are 000 (off) or 0-255 minutes. After typing a standby time value, press the TARE key to enter this value. The display will go into standby mode, confirmed by a blinking LED on the right side of the display. When in standby mode, power is still supplied to the CPU and draws 1/2 of the current as when the display is powered. Press any key to exit standby mode and reactivate the display.
The indicator enters standby mode if no key presses, serial communications, or scale motion occur for the length of time specified on this parameter. Set this parameter to 000 to disable standby mode.
Operator access to piece count mode. Specify DSABLE if piece count mode will not be used. With access disabled, pressing the GROSS/NET (MODE) key toggles between gross and net modes only.

5.0 EDP Commands

Note
The 320IS indicator can be controlled by a personal 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 personal computer. This section describes the EDP command set and procedures for saving and transferring data using the EDP port.

5.1 The EDP Command Set

The EDP command set can be divided into five groups: key press commands, reporting commands, the RESETCONFIGURATION special function command, parameter setting commands, an d transmit weight data commands.
When the indicator processes an EDP command, it responds with the message 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
3. Type KTARE and press
ENTER.
ENTER. The display shifts to net mode when the tare is entered.
OK. The OK response verifies that the

Table 5-2. EDP Reporting Commands

5.1.3 The RESETCONFIGURATION Command

The RESETCONFIGURATION command can be used to restore all configuration parameters to their default values. Before issuing this command, the indicator must be placed in test mode (press and hold setup switch until
TEST
is displayed).
This command is equivalent to using the DEFLT function on the TEST me nu. See Section 7.8 on page 51 for more information about test mode and using the TEST menu.
All load cell calibration settings are lost when the RESETCONFIGURATION command is run.

5.1.4 Parameter Setting Commands

Parameter setting commands allow you to display or change the current value for a particular configuration parameter See Tables 5-3 through 5-12 for more information on menu parameters.
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. 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:
MOTBAND=5D<ENTER>

5.2 Saving and Transferring Data

Note
Note
Note
Saving and transferring data requires the use of an I/O Module.
Connecting a personal computer to the 320IS EDP port allows you to save indicator configurati on 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 8.0 on page 53 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
1
®
communications program such as ProComm Plus
78076) OR, Section 8.0 on page 53, for information about serial co mmunications 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 320IS responds by sending all configuration parameters to the PC as ASCII-formatted text.

5.2.2 Downloading Configuration Data from PC to Indicator

Configuration data saved on a PC or floppy disk can be downloaded from the PC to an indicator. This procedure is useful when a number of indicators with similar configurations are set up or when an indicator is replaced.
To download configuration data, connect the PC to the EDP port as described in Section 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 Section 4.0 on page 31.
Calibration settings are included in the configuration data downloaded to the indicator.
If the receiving indicator is a direct replacement for another 320IS and the attached scale is not changed, recalibration is not required.

6.0 Print Formatting

The 320IS provides four print formats, GFMT, NFMT, and CFMT that determine the format of the printed output when the 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. 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 that can be used 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 entered or

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 personal 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 or NFMT) and press 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 or NFMT 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
ENTER. For
1345 LB GROSS
6.2.2 Using the Front Panel
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 41) 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 front panel (see the ASCII character chart on Table 7-5 on page 45 and Table 7-7 on page 46) and are shown as blanks. The 320IS can send or receive any ASCII character; the character printed depends on the particular ASCII character set implemented for the receiving device.

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.

recurs.

Table 7-1. 320IS Error Messages

7.1.2 Using the XE EDP Command

The XE EDP command can be used to remotely query the 320IS 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 Table 7-2. 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 ( test for the error condition was run. For example, the value
yyyyy) uses the same bit assignments as sh own in Table 7-2 to indicate whether th e
yyyyy = 63487 represents the decimal equivalent of the
binary value 1111 0111 1111 1111. Using the bit assignments in Table 7-2, this value indicates all tests were run.

7.2 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.
7.2.1 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).
7.2.2 Using the ZZ EDP Command
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 7-3). If more than one annunciator is lit, the second number returned is the sum of the values representing the active annunciators.

7.5 Conversion Factors for Secondary Units
Note
The 320IS 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 7-8 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
ou must use the MULT parameter to set the decimal point position. Use the numeric keypad or the
Y
RIGHT keys to select the digit. Use the UP/DOWN keys to increment and decrement. LEFT/RIGHT keys also
select decimal placement. To configure secondary units using EDP commands, use the Table 7-8 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 7-8 cannot be directly specified as primary or secondary units on the 320IS 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 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 7-2 shows the digital filter parameters on the CONFIG menu.

Figure 7-2. Digital Filtering Parameters on the Configuration (CONFIG) Menu

7.6.1 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.

7.6.2 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.
DFTHRH should be set to 10DD for this example. See Figure 3-2 on page 22 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.

8.4 Fiber Optics Assembly
The 320IS is equipped with duplex fiber optic ports for com municating 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 8-1 on page 54 for the location of the fiber optic ports on the 320IS main board.
The fiber optic connections between the indicator and the 320IS need to be cross-linked. The optical output
56 320IS Installation Manual
of the indicator should be attached to the input of the320IS , and the indicator’s input to the module’s output.

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.
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 8-1 on page 54) using wire ties included in parts kit.
Figure 8-4. Fiber Optics Connector
8.5 Analog Outputs
The 320IS use s two 16-bit isolated analog output chann els 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 8-1 on page 54). Analog output configuration is done via setup mode in the indicator used with the 320IS (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 Figure 8-1 on page 54).
The analog output port is powered by an isolated DC-DC converter. The outputs available on connector CN1 are listed in Table 8-8. See Figure 8-1 on page 54 for the location of CN1 and DIP switches.

8.6 Digital Inputs
The 320IS has four digital inputs that can be used to control pre-defined operations in the indicator. Table 8 -9 outlines the various functions for the digital inputs.
Digital inputs are available on connector CN4 (see Figure 8-1 on page 54). All inputs are individually isolated via optocouplers. Table 8-9 outlines the pin connections for CN4.

10 Low DGND
Table 8-9. 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.
8.7 Relay Contact Outputs
The 320IS 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.
Table 8-10 shows pin connections for CN5 of the 320IS board.
