iQUBE Options

Options for the iQUBE include the following;

Internal power supply: The 6 VDC power supply

mounts inside the

iQUBE enclosure and requires a

115/230 VAC input. This option is required for applications that do not use the

920i applications that use more than two iQUBE units,

the distance between the

920i and the master iQUBE is

more than 75 feet, or the fiber optic modules are used. Analog output: This option consists of a DAC card

that mounts on the core module and converts the

iQUBE’s digital output stream to 0–30 mV or 0–20

mA (passive only). Fiber-optic transceiver: This option mounts on the

connector board to convert the

iQUBE’s serial output

into visible light for fiber-optic interface. When used with the optional power supply, the fiber-optic interface provides electrical isolation of the

iQUBE

from the host. Fiber-optic transceiver to analog output: This

option converts digital fiber-optic data received from the

iQUBE to an analog signal that can be input to the

load cell input of a standard weight indicator. Ethernet: This option mounts on the connector board

to transfer the

Configuration

iQUBE’ s serial output onto the Ethernet.

There are two methods for configuration, using either

920i indicator as the host (menu or iRev

the configuration) or by using the Revolution III utility to configure the the load cells connected to

iQUBE directly. Each method defines

iQUBE, which load cells

comprise a platform, and which platforms make up the scale system.

Introduction 1

Configuration consists of the following steps: Define Load Cells: This is the electrical sensitivity

(mV/V output) and capacity specification of the load cells. Load cell names and serial number can also be specified.

Define Platforms: A platform is a contiguous weigh bridge. Any

iQUBE board can assign load cells to two

separate platforms. A maximum of four platforms can be defined in an

iQUBE system. The relationship

between load cells is also defined as a paired or circular arrangement.

Define Systems: The platforms can be assigned to a system. Up to four unique systems can be defined, however the

920i will only support one system per

serial channel.

Error conditions generate a displayed error message if connected to the

920i which, with an Ethernet card,

can be configured to e-mail the alert message to an address. In addition, there is a visual LED indication on the connector board to identify any load cell that appears to have an abnormal condition.

Cell Emulation

Cell emulation allows the output of a failed load cell to be emulated. Automatic or manual cell emulation can be specified (limited to one cell per scale system), using either truck scale (Type 1) or tank/hopper/floor scale (Type 2) emulation algorithms.

NOTE: Satisfactory results from cell emulation require the load to be centered and the scale installation to be plumb and level.

Load Cell Trimming and Calibration

Cal-Match™ calibration calculates the load cell trim based on a comparison of the signal generated by an applied weight for each load cell to the signal generated by all other load cells. If a known test weight value is used, this calibration also sets the span for the scale.

Three types of Cal-Match calibration can be performed using the

iQUBE. Each type of calibration

captures the initial dead load of the scale and provides a means to trim the outputs of the load cells.

Cal-Match Theoretical calibration allows each cell to be zeroed and trim factors calculated. Based on the cell capacity and sensitivity, the

iQUBE calculates

weight values based on the total signal from all of the cells.

Cal-Match Section calibration requires a weight to be placed over each section. Trimming can be performed by running a weight cart down the middle of the platform, stopping for calibration of each section.

Corner calibration requires weight to be placed over each cell individually. Corner trimming can be performed for platforms using an even or odd number of cells.

Diagnostics (Error 2)

Diagnostic functionality can be enabled for the iQUBE to identify abnormal load cell outputs. This is based on the reference established through cell associations. The diagnostic conditions that can be identified for paired configurations are open bridge or channel, zero reference tolerance, drifting, peak-to-peak noise, and out-of-balance conditions. Diagnostic conditions recognized for circular configurations are limited to open bridge or channel, drifting, and peak-to-peak noise.

2 iQUBE Installation Manual

2.0 Installation

This section describes procedures for connecting load cell, analog output, power, and serial communications cables to the drawings and replacement parts lists for the are included for the service technician.

2.1 Unpacking and Assembly

Immediately after unpacking, visually inspect the

iQUBE to ensure all components are included and

undamaged. The shipping carton should contain the

iQUBE, this manual, and a parts kit. If any parts were

damaged in shipment, notify Rice Lake Weighing Systems and the shipper immediately.

See Section 2.16 on page 16 for parts kit contents.

2.2 Mounting the Enclosure

The iQUBE can be mounted either vertically or horizontally to a flat surface.

2.3 Cable Connections

All models of the iQUBE provide ten cord grips for cabling into the unit, plus a dedicated cord grip for a ground wire. Up to eight load cells can be cabled into

iQUBE; other cord grips allow cabling for serial

the communications, analog output, digital I/O, and AC power. Install plugs in all un us ed co rd grips to prev ent moisture from entering the enclosure.

Connector Cell Name

Figure 2-1 shows two exa mples of load cell naming for eight-cell platforms. While load cells can be wired to any connector on the

iQUBE connector board,

platforms defined as using “paired” sections (including most truck scale applications) must correctly associate these pairs to ensure valid calibration and diagnostic functions.

In the top example of Figure 2-1, the even/odd load cell wiring scheme requires cells A1/A2, A3/A4, A5/ A6, and A7/A8 to be associated as section pairs. In the lower example, the sequential wiring requires pair associations for A1/A8, A2/A7, A3/A6, and A4/A5. Pair association is set in the platform configuration for the scale.

2.4 Load Cells

When wiring load cells, cells wired to iQUBE connectors J12–J19 (8-channel units) are assigned default names A1–A8 (8-channel primary unit) or B1–B8 (8-channel secondary unit). Be aware that graphic representations of the weighing platform shown when configuring the scale assume particular locations for each load cell, based on the connector used (see Table 2-1). Load cells can be renamed during configuration.

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.

Given that these and other factors will affect the maximum usable cable length, the following distances can be used as a general guide for

iQUBE

communications cabling:

RS-232: 50 ft (15 m) RS-485: 1000 ft (300 m) (Twised pair cable) Fiber-optic: 500 ft (150 m)

2.6 Primary/Secondary Configuration

Up to three iQUBE junction boxes can be configured as secondary units controlled by a primary unit. Figure 2-4 on page 7 shows the primary-to-secondary wiring for multiple units. Successive secondary units are wired in parallel (A to A, B to B, and so on) as shown in Figure 2-5 .

NOTES:

•120Ω termination resistors (included in parts kit) must be installed across the A and B terminals on the J4 connector of the primary unit and between the A and B terminals on the J7 connector of the last secondary unit (see Figure 2-4 on page 7).

• All six wires, including shield and ground wires, must be connected between the communicating

iQUBE units.

iQUBE

Installation 5

DIP switches on the core module of each iQUBE must be set to indicate whether the unit is a primary or secondary, the communication protocol and port used, and the secondary address.

2.7 Digital I/O

The iQUBE junction box is available with support for eight channels of digital 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, ca pable of sinking 25 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. Auxiliary power is available at connector J20 (see Figure 2-2 on page 4).

Table 2-6 shows the pin assignments for connector J21.
