About This Manual

This manual is intended for use by service technicians responsible for installing and servicing the
Tracer AVi
single channel diagnostic junction box and bagwell display.

1.0 Introduction

The Tracer AVi system consists of three components:
iQubeTM, a digital programmable junction box used with an analog load cell. It outputs a serial string that can be directly input to the remote display and
RD-1 remote display, a .8”, six-digit, seven-segment LED display.
VIRTUiTM, a PC-based indicator for iQube. The virtual front panel consists of display and five-button keypad.
The iQube consists of three boards:
•The connector board provides the physical connections for the load cell, serial communications, and power.
•The core module, which plugs into the connector board, contains the processor and stores configuration and calibration data for the module provides a discrete A/D input and converts the analog load cell signal to a digital serial output.
•The 7.5 VDC power supply mounts inside the enclosure and requires a 115/230 VAC input.
Configuration
The Tra cer AVi system can be configured by using a PC running the
VIRTUi configuration program. This
method defines the load cell connected to which is associated with a platform, and the platform that makes up the scale. Even though the single-channel
iQube is just one cell, one platform,
and one scale; the association of scale and platform is required because the software is also used on multiple cell and multiple platform scales.
Configuration consists of the following steps: Define Load Cell: This is the electrical sensitivity
(mV/V output) and capacity specification of the load cell. Load cell name and serial number can also be specified.
VIRTUi.
Tracer AVi’s
Tracer AVi. The core
iQube,
Some procedures described in this manual require work inside the iQube enclosure. These procedures are to be performed by
qualified service personnel only.
The Tracer AVi does not have an on/off switch and therefore must be installed near a power outlet that is easily accessible and in accordance with UL/CSA Safety Standards.
Define Platforms: The iQube board must assign a load cell to the platform.
Define System: The iQube board must assign the platform to the system.
Load Cell Trimming and Calibration
iQube supports calibration of multiple load cells with
corner match and section match calibration. For the single cell iQube, only multi-point linear
calibration and theoretical calibration apply. Each type of calibration captures the initial dead load of the scale and provides a means to trim the output of the load cell.
Based on the cell capacity and sensitivity, the theoretical calibration calculates weight values based on the total signal from the cell.
Single Cell Diagnostic
Diagnostic functionality can be enabled for the iQube to identify abnormal load cell output. The diagnostic conditions that can be identified are open bridge open channel, drifting, peak-to-peak noise, cell at rail, and cell over/under range.
Error conditions generate a displayed error message if connected to
VIRTUi which can be configured to
email the alert message to an address.
Introduction 1

2.0 Installation

This section describes procedures for connecting load cell, power, and serial communications cables to the
TM
iQube
enclosure. Drawings and replac ement parts
lists are included for the service technician.
Use a wrist strap to ground yourself and
!
protect components from electrostatic discharge (ESD) when working inside the
iQube enclosure.
Disconnect AC power from the main module before installing remote displays.

2.1 Unpacking and Assembly

Immediately after unpacking, visually inspect the contents to ensure all components are included and undamaged. The shipping carton should contain the
iQube, the remote display, this manual, and
connection cables. If any parts were damaged in shipment, notify Rice Lake Weighing Systems and the shipper immediately.
See Table 2-4 on page 4 for the iQube cables.

2.2 Mounting the iQube and Remote Display

The iQube and remote display are two separate components. The main board is installed in the
iQube.
All components can be installed in separate locations. The iQube can be placed either upright or on its side.
Mounting hardware is not included in the parts kit.

2.3 Cable Connections

The single channel iQube provides one load cell connector, two remote display connectors, one host (PC) com port connector for connecting to the PC running
VIRTUi, and an AC power cord.

2.4 Load Cells

The load cell wired to connector J3 in the iQube, is assigned a default name A1. J3 is wired to a DB-9 on the enclosure panel.

To reload the default firmware into the iQube core module, do the following:
1. Power-off the iQube. Remotely powered units
2. Set core module DIP switch 8 ON.
3. Power-on the iQube.
4. Power-off the iQube.
5. Set DIP switch 8 OFF.

can be powered off by temporarily removing fuse F1 (see
Figure 2-1 on page 2).
Table 2-2. Serial Port Pin Assignments
Communications Cable Distance Limitations
The maximum cable lengths that can be used for various communications types depend on a number of factors. These include: output impedance of the transmitter; electrical noise in the environment; cable capacitance, gauge, termination, and shielding.

3.0 PC Configuration

The iQubeTM can be configured using a PC running VIRTUi.

3.1 Introduction to VIRTUi

VIRTUi is a PC-based virtual indicator designed to replicate the form and function of a single function indicator.
The virtual front panel consists of a display and five-button keypad. Keys are activated by a mouse click. Features included:
Electronic data processing (EDP) port for full-duplex, RS-232 communications up to 57600 bps
Printer port for output-only, RS-232 communications up to 57600 bps
Figure 3-1. VIRTUi Main Screen
VIRTUi is NTEP-Certified for Classes III and III L at
10,000 divisions
NOTES:
To send and receive commands from VIRTUi using HyperTerminal:
1. Open HyperTerminal on the PC
2. Connect to “localhost” on port 20355 using TCP/IP
By default, VIRTUi is always the top window within

Windows
. This is required by NTEP to ensure the weight is visible at all times. This can be changed in the Application Settings if Legal-for-Trade requirements are
not necessary.
Auto-Update Feature
If connected to the Internet, VIRTUi’s Auto-update feature will automatically download updates to the program. The auto-update feature will only function if the user is logged in to Windows as “Administrator” and/or if the user has “write” access to the application installation directory.

3.1.1 Authentication/Authorization System

The User Manager is a security feature of VIRTUi and is used to set up
VIRTUi users, their “roles” and the
permissions for those roles. The User Manager for authentication/authorization can be found under the File menu. After installing
VIRTUi, the user must
logon as “Administrator” to access the User Manager.

Function Keys
The function keys below perform the front panel functions via the computer keyboard:
Key F5 F6 F7 F8 F9
Function Zero Gross/Net Ta re Units Print
Table 3-1. Function Keys
Annunciators
The VIRTUi display uses a set of eight annunciators to provide additional information about the value being displayed:
Gross and Net annunciators are lit to show whether the display weight is a gross or net weight
Center of Zero: Gross weight is within 0.25 graduations of zero. This annunciator lights when the scale is zeroed
Standstill: Scale is at standstill or within the specified motion band. Some operations, including tare functions and printing, can only be done when the standstill symbol is shown
The display units can also be set to short tons (tn), metric tons (t), or NONE (no units information displayed). The lb and kg annunciators default as primary and secondary unit annunciators. Changing unit annunciators under the Settings menu will also change the annunciators on the
