Enclosures

The 920i

is available in four enclosures: universal(tilt-stand), desktop, panel mount, and wall mount.Stainless steel enclosures are rated for NEMA4X/IP66. This manual provides assembly drawingsand replacement parts lists for the universal anddesktop models; supplemental documentationprovides information specic to the panel mount andwall mount models (Section 1.4 on page 4).

1.1 Operating Modes

The 920i

has two modes of operation:

Normal mode

Normal mode is the weighing mode of theindicator. The indicator displays gross, net, or tareweights as required, using the secondary displayto indicate scale status and the type of weightvalue displayed. Once conguration is completeand a legal seal is afxed to the large llister-headscrew on the indicator enclosure, this is the onlymode in which the 920i

can operate.

Setup mode

Most of the procedures described in this manualrequire the indicator to be in setup mode,

including conguration and calibration.To enter setup mode, remove the large llisterhead screw from the enclosure. Insert ascrewdriver or a similar tool into the access holeand press the setup switch once. The indicatordisplay changes to show scale congurationmenus.

models are included for the service technician. SeeSection 10.11 on page 102 for dimension drawings ofthe all models.

Use a wrist strap to ground yourself and protect

com ponent s f rom elec t ros tat ic discharge (ESD)

when working inside the indicator enclosure.

This unit uses double pole/neutral fusing which

could c reate an electric shock hazard. Procedures

r e q u i r i n g wo r k i n s i d e t h e i n d i c a t o r mu s t b e

perfo rmed by qualified service personnel only.

The supply cord serves as the power disconnect forthe920i. The pow er outlet supplying the indicator

mu s t be i ns t a l l ed nea r t he un i t and be eas i ly

accessible.

2.1 Unpacking and AssemblyImmediately after unpacking, visually inspect the 920ito ensure a l l componen ts a re inc luded andundamaged. The shipping carton should contain theindicator, this manual, and a parts kit. If any partswere damaged in shipment, notify Rice LakeWeighing Systems and the shipper immediately.

See Section 2.10 on page 12 for parts kit contents.

2.2 Enclosure DisassemblyThe indicator enclosure must be opened to installoption cards and to connect cables for installed optioncards.

The920i has no on/off switch. Before

opening the unit, ensure the power cord

is disconnected from the power outlet.

Ensure power to the indicator is disconnected, thenplace the indicator face-down on an antistatic workmat. Remove the screws that hold the backplate to theenclosure body, then lift the backplate away from the

enclosure and set it aside.2.3 Cable ConnectionsDesktop and universal models of the 920iprovide sixcord grips for cabling into the indicator: one for thepower cord, ve to accommodate cabling for optioncards. Install plugs in all unused cord grips to preventmoisture from entering the enclosure.

2.3.1 Cable Grounding

Except for the power cord, all cables routed throughthe cord grips should be grounded against t heindicator enclosure. Do the following to ground

shielded cables: Use the lockwashers, clamps, and kep nuts

provided in the parts kit to install groundingclamps on the enclosure studs adjacent to cordgrips. Install grounding clamps only for cordgrips that will be used; do not tighten nuts.

Route cables through cord grips and groundingclamps to determine cable lengths required toreach cable connectors. Mark cables to removeinsulation 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 wherethe cable passes through the clamp. Ensuresilver (conductive) side of foil is t urnedoutward for contact with the groundingclamp.

For cables with braided shielding, strip cableinsulation and braided shield from a point justpast the grounding clamp. Strip another halfinch (15 mm) of insulation only to expose thebraid where the cable passes through theclamp (see Figure 2-1).

Figure 2-1. Grounding Clamp Attachment for Foil-Shielded

and Braided Cabling

For load cell cables, cut the shield wire just pastthe grounding clamp. Shield wire function isprovided by contact between the cable shieldand the grounding clamp.

Route stripped cables through cord grips andclamps. Ensure shields contact groundingclamps as shown in Figure 2-1. Tightengrounding clamp nuts.

Finish installation using cable ties to securecables inside of indicator enclosure.

2.3.2 Loa d Cells

To attach cable from a load cell or junction box to aninstalled A/D card, route the cable through the cordgrip and ground the shield wire as described inSection 2.3.1 on page 6.

Next, remove connector J1 from the A/D card. The

connector plugs into a header on the A/D card (seeFigure 2-2). Wire the load cell cable from the load cellor junction box to connector J1 as shown in Table 2-1.

Figure 2-2. Single-Channel A/D Card

If using 6-wire load cell cable (with sense wires),remove jumpers JP1 and JP2 before reinstallingconnector J1. For 4-wire installation, leave jumpers

JP1 and JP2 on. For 6-wire load cell connections ondual-channel A/D cards, remove jumpers JP3 and JP4for connections to J2.

When connections are complete, reinstall load cellconnector on the A/D card and use two cable ties tosecure the load cell cable to the inside of theenclosure.

2.3.3 Serial Communications

The four communications ports on the 920iCPUboard support full duplex RS-232, 20 mA output, orRS-485 communications at up to 115200 bps.

To attach serial communications cables, route thecable through the cord grip and ground the shield wire

as described in Section 2.3.1 on page 6. Remove theserial connector from the CPU board and wire to theconnector. Once cables are attached, plug theconnector into the header on the board. Use cable tiesto secure serial cables to the inside of the enclosure.

Table 2-2 shows the pin assignments for Ports 1, 3,and 4. Port 2 provides DIN-8 and DB-9 connectors forremote keyboard attachment of PS/2-type personalcomputer keyboards (see Figure 2-3 on page 8). TheDB-9 connector pin assignments for Port 2 are shownin Table 2-3 on page 8; see Section 10.3 on page 91for information about the PS/2 keyboard interface.

Serial ports are congured using the SERIAL menu.See Section 3.2.2 on page 30 for congurationinformation.

An optional dual-channel serial communicationsexpansion card, PN 67604, is also available. Eachserial expansion card provides two additional serial

ports, including one port that supports RS-485communications. Both ports on the expansion cardcan support RS-232 or 20mA connections.

2.3.4 Digita l I/O

Digital inputs can be set to provide many indicatorfunctions, including all keypad functions. Digitalinputs are active low (0 VDC), inactive high (5 VDC).

Digital outputs are typically used to control relays thatdrive other equipment. Outputs are designed to sink,

rather than source, switching current. Each output is anormally open collector circuit, capable of sinking 24mA when active. Digital outputs are wired to switchrelays when the digital output is active (low, 0 VDC)with reference to a 5 VDC supply.

Table 2-4 shows the pin assignments for connector J2.

Digital inputs and outputs are congured using theDIG I/O menu. See Section 3.2.6 on page 37 forconguration information.

An optional 24-channel digital I/O expansion card,PN 67601, is available for applications requiring moredigital I/O channels.

2.4 Installing Option CardsEach option card is shipped with installationinstructions specic to that card. The generalprocedure for all option cards is as follows:

2.8 Fuse ReplacementFuses for the desktop and universal models of the 920iare located under a cover plate on the outside of theenclosure. Remove the cover plate, replace the fuses,and reinstall the cover plate (see Figures 2-12 and2-13).

To p rotec t against th e risk of fire,

replace fuses only with same type and

rating fuse.

See Section 10.13 on page 107 for complete fusespecications for the desktop and universal units.

Interface board and fuse access cover

plates must be in place for use in

NEMA 4X/IP66 applications.

2.9 Battery ReplacementThe lithium battery on the CPU board maintains thereal-time clock and protects data stored in the systemRAM when the indicator is not connected to ACpower.

Data protected by the CPU board battery includestime and date, truck and tare memory, onboarddatabase information, and setpoint conguration.

Use iRevto store a copy of the indicator congurationon a PC before attempting battery replacement. If anydata is lost, the indicator conguration can be restoredfrom the PC.

NOTE: Memory op tion card data is also protected by alithium battery. All database information stored on a

mem ory card is lost if the memory card battery fails.Watch for the low battery warning on the LCD displayand periodically check the battery voltage on both theCPU board and on any installed memory option cards.Batteries should be replaced when the indicator lowbattery warning comes on, or when battery voltagefalls to 2.2 VDC. Life expectancy of the battery is tenyears.

See Figure 2-4 on page 8 for CPU board batterylocation and orientation (positive side up).

3.0 Configura tion

To congure the 920i indicator, the indicator must beplaced in setup mode. The setup switch is accessed byremoving the large llister head screw on the desktopand universal enclosures. Switch position is changed

by inserting a screwdriver into the access hole andpressing the switch.

When the indicator is placed in setup mode, a series ofmenus is shown across the top of the display, alongwith the words Scale Configura tion. The SCALESmenu is highlighted as the rst used to congure theindicator. Detailed descriptions of these menus areprovided in Section 3.2.

When conguration is complete, press the Exit orSave and Exit softkey to exit setup mode, then replacethe setup switch access screw.

The Exit softkey exits setup mode withoutsaving parameter changes to NV RAM. Changesmade to the conguration remain in the systemuntil indicator power is cycled.

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

3.1 Configuration MethodsThe 920i indicator can be congured by using thefront panel keys to navigate through a series ofconguration menus or by sending commands orconguration data to an indicator serial port.Conguration using the menus is described in

Section 3.1.3.Co n g u ra t io n u s in g th e s e r i a l p o r t c an b eaccomplished using either the serial command setdescribed in Section 9.0 or the iRevcongurationutility.

NOTE: Some conguration parameters, such as thoseused to congure the 920idisplay and widgets, cannotbe accessed through the conguration menus. iRevprovides the most complete and efcient congurationinterface for the 920i.

3.1.1 iRev Configuration

The iRevconguration utility provides the preferredmethod for conguring the 920i indicator. iRev runson a personal computer to set congurationparameters for the indicator. When iRevcongurationis complete, conguration data is downloaded to theindicator.

iRevsupports both uploading and downloading ofindicator conguration data. This capability allowsconguration data to be retrieved from one indicator,edited, then downloaded to another indicator with anidentical hardware conguration.

Figure 3-1. iRev Hardware Conguration Display

To use iRev, do the following:

1. Install iRev on an IBM-compatible personalcomputer. See Section 5.0 on page 44 fordetailed hardware and software requirements.

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

3. Power up the PC and the indicator. Use thesetup switch to place the indicator in setupmode.

4. Start the iRevprogram.iRevprovides online help for each of its congurationdisplays. Parameter descriptions provided in this

manual for front panel conguration can also be usedwhen conguring the indicator using iRev: Theinterface is different, but the parameters set are thesame.

See Section 5.0 on page 44 for more information aboutusing iRevto congure the 920i.

3.1.2 Serial Command Configuration

The serial command set can be used to congure the920i indicator using either a personal computer,terminal, or remote keyboard. Like iRev, serialcommand conguration sends commands to theindicator serial port; unlike iRev, serial commands can

be sent using any external device capable of sendingASCII characters over a serial connection.

Serial commands duplicate the functions availableusing the indicator front panel and provide somefunctions not otherwise available. Serial commandscan be used to simulate pressing front panel keys, tocongure the indicator, or to dump lists of parametersettings. See Section 9.0 on page 72 for moreinformation about using the serial command set.

Configuration 21

3.1.3 Front Panel Configuration

Use the CONFIG submenu under the SCALES menuto congure A/D scales. For example, in an indicatorwith a single-channel A/D card installed in Slot 1, theScale Conguration display will show the A/D listed(Slot 1 Channel 1) under the AVAILABLE A/Dscolumn.

Use the left navigation key to select the A/D, thenpress the center softkey, Add . The A/D is then movedto the Associated A/Ds column. If no other A/Ds arelisted in the AVAILABLE A/D scolumn, the centersoftkey changes to Done, as shown in Figure 3-2.Press Done to exit the Scale Conguration display.

See Section 10.4 on page 91 for information aboutconguring serial scales.

Figure 3-2. Scale Conguration Display

The 920iindicator can be congured using a series of menus accessed through the indicator front panel when theindicator is in setup mode. Table 3-1 summarizes the functions of each of the main menus.

3.2 Menu Structures a nd Parameter DescriptionsThe following sections provide graphic representations of the 920imenu structures and tables describing themenu parameters. Default values are shown in bold type; numeric ranges and string values are shown in italictype.

M ULT 1.0

0.0000019999999

M ultiplier. S pecifies the conversion factor by which the primary units are multiplied by to

obtain the displayed rate of change units.

To calculate the M ULT value, use the following equation:

M ULT = (SM PR AT / INTERVL) * (seconds_per_ROC_unit)* (ROC/PRIMAR_precision_adjustment)

Where:

SM PRAT is the value specified for the A/D sample rate on the SCALES menu

INT ERVL is the specified RO C interval

seconds_per_ROC_unitis an adjustment for the RO C UN ITS parameter. If RO C UNITSis set to SEC , use 1; use 60 for UNIT S= M IN, use 3600 for UNIT S= HO UR .

ROC/PRIMAR_precision_adjustmentcompensates for any difference in the DEC PNTand DS PDIV parameters specified for primary units and R O C units. For example, if the

R O C DE C P NT parameter is set to 8888888 (no decimal) and with DSP DIV = 1, R O C

precision is 1. I f P R IM AR D EC P N T is set to 8888880 (null units position) and

DSP DIV= 2, P R IM AR 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 SM PR AT= 120HZ, INT ERVL= 240, R O C UN ITS= M IN, and the precision is

compensated as described above, M ULT would be calculated as follows:M ULT = (120 / 240) * 60 * 0.05 = 1.5

To calculate a R O C M ULT value based on secondary or tertiary units, multiply the calculated

primary units M ULT value by the conversion factor for the alternate units. For example, if a

M ULT value of 1.5 is calculated for pounds as the primary unit, calculate the M ULT value for

kilogram secondary units by multiplying the original M ULT value by 0.453592:

M ULT (kg)= 1.5 * 0.453592 = 0.680388

See Section 10.10 on page 101 for information about conversion factors.

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

REFRESH 1

165535Refresh 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 (INTER VL parameter) specified. For example, if the INT ER VL

parameter value is 120, the R EFR ESH specified should be in the range of 260.
