1.0Introduction

The 720i is a single-channel, programmable digital weight indicator/controller. The configuration can be performed using the front panel, with an attached

PS/2®1-type keyboard, or using the Revolution III utility.

The 720i can be loaded with either PCE software or 720i batching software. Refer to Section 8.0 on page 65 or Section 9.0 on page 81 for further information on each of these software choices.

Onboard Features

Features of the basic 720i include:

Support for a single A/D or serial scale input.

Eight digital I/O channels on main board, each configurable as either input or output.

Two serial ports on main board support duplex RS-232 up to 115200 bps. Port 2 supports RS-232 with hardware handshaking; Port 4 supports RS-232 and 20mA communications.

Available in 115 VAC and 230 VAC North American and European versions.

Configurable print formats can be defined for up to 1000 characters each using serial commands or Revolution III. These formats are used to print gross or net weights, truck in/out weights, accumulator weights, alert messages, and header information. Additional print formats can be created using twenty auxiliary print formats.

Seven truck modes to store and recall weights for gross, tare, and net printing. The truck register contains fields for ID number, weight, and the transaction time and date. Weights can be stored permanently or erased at the end of the transaction.

Support Applications

In addition to Revolution III, the 720i is supported by two Windows-based applications that extend its capabilities for batch control and database management. ProAction PCEE, or Process Control Engine Editor, provides functions similar to setpoint configuration for 720i-based batch control. ProAction DBE, the database editor, is a tool for creating, editing, and managing databases in the 720i. Both applications are included on the 720i Toolkit CD.

1.1Operating Modes

The 720i has two modes of operation:

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, press the MENU key on the front panel, select Configuration, then press Enter. The indicator display changes to show scale configuration menus.

Jumper J9 (see Figure 2-3 on page 9) must be

Note installed to enable access to setup mode. When configuration is complete, remove the jumper (place the jumper on a single pin of J9) to disable access to the configuration menus.

Normal mode

Normal mode is the weighing mode of the indicator. The indicator displays gross, net, or tare weights as required, using the secondary display to indicate scale status and the type of weight value displayed. Once configuration is complete, remove jumper J9 and affix a legal seal to the fillister-head screws on the indicator enclosure.

1.2Indicator Operations

Basic 720i operations are summarized below:

Display Menu

Press the MENU key to show the system menu, then use the Up or Down navigation keys to select an item from the list. The menu provides access to audit trail information, configuration, test operations, and display contrast adjustment.

Introduction 5

2.0Installation

This section describes procedures for connecting load cell, digital I/O, and serial communications cables to the 720i indicator. Assembly drawings and replacement parts lists for the universal model are included for the service technician. See Section 11.13 on page 111 for dimension drawings.

CAUTION

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

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

The supply cord serves as the power disconnect for the 720i. The power outlet supplying the indicator must be installed near the unit and be easily accessible.

2.1Unpacking and Assembly

Immediately after unpacking, visually inspect the 720i to ensure all components are included and undamaged. The shipping carton should contain the indicator, this manual, and a parts kit. If any parts were damaged in shipment, notify Rice Lake Weighing Systems and the shipper immediately.

See Section 2.9 on page 11 for parts kit contents.

2.2Enclosure Disassembly

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

The 720i has no on/off switch. Before WARNING opening the unit, ensure the power cord is

disconnected from the power outlet.

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

2.3Cable Connections

The universal model of the 720i provides six cord grips for cabling into the indicator: one for the power cord, five to accommodate other cabling. Install plugs in all unused cord grips to prevent moisture from entering the enclosure.

2.3.1Cable Grounding

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

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

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

For cables with foil shielding, strip insulation and foil from the cable half an inch (13 mm) past the grounding clamp (see Figure 2-1). Fold the foil shield back on the cable where the cable passes through the clamp. Ensure silver (conductive) side of foil is turned outward for contact with the grounding clamp.

For cables with braided shielding, strip cable insulation and braided shield from a point just past the grounding clamp. Strip another half inch (13 mm) of insulation only to expose the braid where the cable passes through the clamp (see Figure 2-1).

NOTE: Install lockwashers first, against backplate, under grounding clamp

Figure 2-1. Grounding Clamp Attachment for Foil-Shielded and Braided Cabling

6720i Installation Manual

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

Route stripped cables through cord grips and clamps. Ensure shields contact grounding clamps as shown in Figure 2-1. Tighten grounding clamp nuts.

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

2.3.2Load Cells

To attach cable from a load cell or junction box to the 720i, route the cable through the cord grip and ground the shield wire as described in Section 2.3.1 on page 6.

Next, remove load cell connector J1 from CPU board. Wire the load cell cable from the load cell or junction box to the connector as shown in Table 2-1.

2.3.3Serial Communications

Communications ports on the 720i CPU board support PS/2-type remote keyboard, full duplex RS-232, and 20 mA output communications at up to 115200 bps. Optional communications cards support USB, Ethernet, and fiber-optic connections to the 720i.

To attach serial communications cables, route the cable through the cord grip and ground the shield wire as described in Section 2.3.1 on page 6. Remove the serial connector from the CPU board and wire to the connector. Once cables are attached, plug the connector into the header on the board. Use cable ties to secure serial cables to the inside of the enclosure.

Table 2-2 shows the pin assignments for Ports 1, 2, and 4. Port 1 supports remote keyboard attachment of PS/ 2-type personal computer keyboards (see Section 11.9 on page 109 for information about the PS/2 keyboard interface.)

An optional dual-channel serial communications expansion card, PN 67604, is also available. The serial expansion card provides two additional serial ports, assigned as port numbers 7 and 8. One port on the serial expansion card supports four-wire RS-485 communications. Both ports on the expansion card can support RS-232 or 20mA connections.

Installation of option cards in connector J11

Note requires removal of the PORT2/OPTI port

selection jumper (see Figure 2-3 on page 9). Install the jumper to enable RS-232 communications through connector J2; remove the jumper to enable an USB, fiber-optic, or Ethernet option card installed in connector J11.

See the communications interface card installation instructions for more information.

2.3.4Digital I/O

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

Digital outputs are typically used to control relays that drive other equipment. Outputs are designed to sink, rather than source, switching current. Each output is a normally open collector circuit, capable of sinking 24 mA when active. Digital outputs are wired to switch relays when the digital output is active (low, 0 VDC) with reference to a 5 VDC supply.

Torqued screws may become less tight as Important the gasket is compressed during torque

pattern, therefore a second torque is required using the same pattern and torque value.

2.8Battery Replacement

The lithium battery on the CPU board maintains the real-time clock and protects data stored in the system RAM when the indicator is not connected to AC power.

Data protected by the CPU board battery includes time and date, truck and tare memory, and onboard database information.

Use Revolution IIIto store a copy of the indicator configuration on a PC before attempting battery replacement. If any data is lost, the indicator configuration can be restored from the PC.

Watch for the low battery warning on the LCD display and periodically check the battery voltage on both the CPU board and on any installed memory option cards. Batteries should be replaced when the indicator low battery warning comes on, or when battery voltage falls to 2.2 VDC. Life expectancy of the battery is ten years.

Replacement Procedure

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

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

1.Place indicator in setup mode.

2.Go to the Version menu and press the RSConfig softkey. If connected using Revolution III, configuration can be reset by using monitor mode to enter the RESETCONFIGURATION command followed by the RS command.

See Figure 2-3 on page 9 for CPU board battery location and orientation (positive side up).

Risk of explosion if battery is replaced WARNING with incorrect type. Dispose of batteries

per manufacturer instruction.

3.1Configuration Methods

The 720i indicator can be configured by using the front panel keys to navigate through a series of configuration menus or by sending commands or configuration data to an indicator serial port. Configuration using the menus is described in Section 3.1.3 on page 19.

Configuration using the serial port can be accomplished using either the serial command set described in Section 10.1 on page 86 or the Revolution III® configuration utility and there are two software modules available:

720i PCE

720i Batching

Some configuration parameters cannot be

Note accessed through the configuration menus.

Revolution III provides the most complete and efficient configuration interface for the

720i.

3.1.1Revolution Configuration

The Revolution III configuration utility provides the preferred method for configuring the 720i indicator. Revolution III runs on a personal computer to set configuration parameters for the indicator. When Revolution III configuration is complete, configuration data is downloaded to the indicator.

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

To use Revolution III, do the following:

1.Install Revolution III on an IBM-compatible personal computer. See Section 5.0 on page 50 for detailed hardware and software requirements.

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

3.Power up the PC and the indicator. To enter setup mode, see “Configuration” above.

4.Start the Revolution III program.

Figure 3-2. Revolution III Display for 720i PCE Version

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

See Section 5.0 on page 50 for more information about using Revolution III to configure the 720i.

18 720i Installation Manual

3.1.2Serial Command Configuration

The serial command set can be used to configure the 720i indicator using either a personal computer, terminal, or remote keyboard. Like Revolution III, serial command configuration sends commands to the indicator serial port; unlike Revolution III, serial commands can be sent using any external device capable of sending ASCII characters over a serial connection.

Serial commands duplicate the functions available using the indicator front panel and provide some functions not otherwise available. Serial commands can be used to simulate pressing front panel keys, to configure the indicator, or to dump lists of parameter settings. See Section 10.1 on page 86 for more information about using the serial command set.

3.1.3Front Panel Configuration

By default, the 720i is configured to use the installed single-channel A/D as the source for Scale 1. To configure the 720i for serial scale support, use the CONFIG submenu under the SCALES menu.

For example: to configure a serial scale, set the serial input function (SERIAL menu) for Port 4 (or Port 7, if using a serial expansion card) to SCALE or INDUST (see Section 3.2.2 on page 33). Return to the top-level SCALES menu, then go D o w n to Scale 1 Configuration, Right to CONFIG (Scale Hardware Configuration), then Down once more to show the scale source options. Use the Right or Left navigation key to change the default A/D value to PORT 4 (or PORT 7) as shown in Figure 3-3.

CONFIG

PORT 4

Figure 3-3. Scale Hardware Configuration Display

See Section 11.3 on page 102 for more information about configuring serial scales.

3.1.4Multi-Range and Multi-Interval Scales

The 720i supports multi-range and multi-interval scales of either two or three ranges or intervals.

Multi-range scales provide two or three ranges, each extending from zero to the maximum capacity specified for the range, that can specify different scale display divisions. The scale interval range changes as the applied weight increases but does not reset to lower range until the scale returns to zero.

Multi-interval scales divide the scale into two or three partial weighing ranges, each with different scale display divisions. The scale interval changes with both increasing and decreasing loads applied.

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

The SPLIT parameter is used to enable multi-range or multi-interval. The SPLIT parameter is in the SCALES menu, see Figure 3-7, and Table 3-2. After setting the SPLIT parameter, the Format menu selection will change as shown in Figure 3-9, and Table 3-4.

If using streaming with multi-range or multi-interval, the stream must be set to Custom in Revolution III. The Tokens for Secondary and Tertiary Units must be set to L or K to match the Primary, refer to the Serial Menu, Tokens Parameter, in Section 3.2.2 on page 33. They can be set using Revolution III or through the front panel.

In multi-range, each range has its own capacity and display division, extending from zero. The scale display division will increase at the entered range capacities, either two or three ranges. Once the range has increased to the next level, the display division will remain in new range until the scale returns to zero. The tare value can be taken in any range.

For example,

Range 1 is 0 - 3000 x 1 lb.

Range 2 is 0 - 10,000 x 5 lb.

In multi-interval, the scale has one capacity, which is segmented into weighing intervals, either two or three intervals, each with different display division sizes. As the weight value exceeds an interval or set interval, the display division will increase, as the weight falls below an interval or set interval, the display division will decrease. The tare can only be taken in the first interval.

For example,

Range 1 is 0-30 x 0.01 lb.

Range 2 is 30 - 60 x 0.02 lbs.

3.2Menu Structures and Parameter Descriptions

Level 3 submenus

 

 

 

 

 

 

 

 

 

 

 

 

 

GRADS

 

10000

Specifies the number of full scale graduations if SPLIT=OFF. (For multi-range and

 

 

1–9999999

multi-interval scales (SPLIT OFF), the GRADS value is derived from the capacity and

 

 

 

display divisions specified for the range or interval.)

 

 

 

The value entered must be in the range 1–9999999 and should be consistent with legal

 

 

 

requirements and environmental limits on system resolution.

 

 

 

To calculate GRADS, use the formula: GRADS = Capacity / Display Divisions.

 

 

 

Display divisions are specified under the FORMAT submenu.

 

 

 

 

SPLIT

 

OFF

Specifies whether the scale is full-range (OFF), multi-range (2RNG, 3RNG), or multi-interval

 

 

2RNG

(2INTVL, 3INTVL). For multi-range and multi-interval scales, see the submenu shown in

ROC

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

ZTRKBND

 

0

Automatically zeroes the scale when within the range specified, as long as the input is

 

 

number

within the ZRANGE and scale is at standstill. Specify the zero tracking band in ± display

 

 

 

divisions. Maximum legal value varies depending on local regulations.

 

 

 

 

 

 

 

 

 

 

Note

For scales using linear calibration, do not set the zero tracking band

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

to a value greater than that specified for the first linearization point.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

ZRANGE

 

1.900000

Selects the range within which the scale can be zeroed. The 1.900000 default value is ±

 

 

number

1.9% around the calibrated zero point, for a total range of 3.8%. Indicator must be at

 

 

 

standstill to zero the scale. Use the default value for legal-for-trade applications.

 

 

 

 

MOTBAND

 

1

Sets the level, in display divisions, at which scale motion is detected. If motion is not

 

 

number

detected for 1 second or more, the standstill symbol lights. Some operations, including

 

 

 

print, tare, and zero, require the scale to be at standstill. Maximum legal value varies

 

 

 

depending on local regulations.

 

 

 

If this parameter is set to 0, the standstill annunciator will be set continuously on, and

 

 

 

operations including zero, print, and tare will be performed regardless of scale motion. If 0 is

 

 

 

selected, ZTRKBND must also be set to 0.

 

 

 

 

SSTIME

 

10

Specifies the length of time the scale must be out of motion, in 0.1-second intervals, before

 

 

number

the scale is considered to be at standstill. Values greater than 10 are not recommended.

 

 

 

 

OVRLOAD

 

FS+2%

Determines the point at which the display blanks and an out-of-range error message is

 

 

FS+1D

displayed. Maximum legal value varies depending on local regulations.

Selects the digital filtering rate used to reduce the effects of mechanical vibration from the

DIGFLT2

8

immediate area of the scale.

DIGFLT3

16

Choices indicate the number of A/D conversions per update that are averaged to obtain the

 

32

 

displayed reading. A higher number gives a more accurate display by minimizing the effect

 

64

 

of a few noisy readings, but slows down the settling rate of the indicator.

Sample rate. Selects measurement rate, in samples per second, of the analog-to-digital

 

120HZ

converter. Lower sample rate values provide greater signal noise immunity: the default 120

 

240HZ

Hz value may be too fast to provide the desired stability in some static weighing

PWRUPMD

GO

Power up mode. In GO mode, the indicator goes into operation immediately after a brief

 

DELAY

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 repeated.
