1.0 Introduction
The CB-2 is a versatile, efficient concrete batching control system ideal for ready-mix, central mix, and block
plants. The CB-2 makes it easy and affordable to streamline your plant. From weighing raw material to automatic
printing of tickets and reports, the entire operation can be cost-effectively controlled from this one controller.
iRev provides functions for installing the new software into the CB-2.
Standard Features - Hardware
Standard hardware features of the CB-2 include:
• Panel type 920i HMI digital indicator that can
control up to three scales
• Six totalizing counters for units with admix
metering
• One addition totalizing counter for units with
metered water
• Twenty switch board assemblies with their
associated switches and appropriate
annunicators which are mounted on the front
panel of the CB-2 enclosure
• 920i expansion card with 1MB of memory
• Four digital I/O boards
• 4 - 24 channel relay boards
• Standard manual override controls
Standard Features - Software
Standard software features of the CB-2 include the
following:
• One aggregate and one cement scale sampling
60 times per second
• Batch/Load report
• Automatic aeration control for cement silos
and weigh hoppers
• Multiple free fall values per material with
automatic “learning” abilities
• Split batching for loads larger than plant
capacity with pre-weighing next batch for
maximum throughput
• Automatic dust collection outputs
• Precision control of inching gates for
aggregate and cement discharge
• Passcode protection
• U.S. or metric units
• Order loading with customer, job site, directions,
and special instructions
2 Installation/Operation Manual
Front Panel
The 920i front panel, shown in Figure 1-1, consists of a 27-button keypad with a large backlit LCD display. The
keys are grouped as five configurable softk
eys, five primary scale function keys, four navigation keys, and
numeric entry keys.
Two scale widgets can be displayed in standard metered water
applications. Status areas on the display are used
for operator prompts and entering data. Display contrast can be adjusted with the LCD contrast potentiometer.

1.1 Operating Modes
The 920i in the CB-2 automated concrete batching
system has two basic modes of operation:
Normal mode
Normal mode is the weighing mode of the
indicator. The CB-2 “program” only executes in
Normal Mode. The weight is only displayed in
Normal Mode. Once configuration is complete
and a legal seal is affixed to the large fillister-head
screw on the indicator enclosure, this is the only
mode in which the

will be driven by softkey selections. As softkeys
are collectively named in the Main Menu. On the
far right of the main menu is the “Admin Menu”
softkey. The Admin Menu may be passcode
protected. The Admin Menu is where all
configuration and database entry takes place. A

nfiguration Mode) is entered by pressing the
Co
setup switch. Setup Mode will be used during the
initial installation of the CB-2. Calibration of the
scales, configuration of filtering and motion band,
and upgrading the CB-2 software are some of the
important tasks that require the indicator to be in
Setup Mode. Once the CB-2 has been installed
and calibrated, there will probably be only three
reasons to ever enter Setup Mode again;
• Annual service calibration of scales
• Adding a PS/2 keyboard
• Upgrading the CB-2 software
Section 3 of this manual explains the Scale

Mode.
To enter setup mode, remove the l
arge fillister
head screw from the enclosure. Insert a
screwdriver or a similar tool into the access hole
and press the setup switch once. The indicator
display changes to show scale configuration
menus.

A few of the procedures described in this manual
require the indicator to be in setup mode,
including configuration and calibration.

Installation/Operation Manual - Introduction 3
1.2 Indicator Operations
The CB-2 does not allow the 920i to execute any of its standard operations like Gross/Net, Units, Print, Tare, and
Zero because they are not applicable to this application. In other words, the Gross/Net, Tare, Units, and Print
keys are disabled all the time. The Zero key is allowed at times during the loading process and while no load is
batching.
Zero Scale Process
Because the CB-2 always has two or more scales, the zeroing of the scale is a three-step process. Only the scale
that is selected can be zeroed. There are two ways to tell which scale is selected. First, the top weight widget will
show Scale #1 and display the current weight in/on scale #1 when scale # 1 is selected. It will show Scale #2 if
cement scale is selected and so on. Also, the selected scale # is displayed in the upper right hand corner of the
display.
Remember that the scale assignments will always be:
Aggregate Scale 1
Cement Scale 2
Water Scale 3
Example: To zero the cement scale;
1. Press the Zero key. If zeroing is not allowed at this time, you will be informed. If zeroing is allowed, the

WARNING
This section explains the main junction box, load cell, digital I/O, and serial communications connections located
inside of the CB-2. The 920i HMI indicator is housed inside the CB-2 enclosure which is shown below in
Figure 2-1 along with examples of several oth
er key component parts.
Figure 2-1. CB-2 Enclosure
• 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 920i. The power outlet supplying the indicator
must be installed near the unit and be easily accessible.
Installation/Operation Manual - Installation 5
2.1 Important Notes
2.1.1 Two Power Sources
The CB-2 requires two separate power sources to run. The power cord that came wired to your CB-2 ONLY
powers the electronics. This power should come from a quality UPS with power conditioning. This clean power
must be separated as far as possible (distance in the electrical circuit) from the power source used to power the
motion control on the batch plant.
Another power source must be brought into the CB-2 to power the I/O (output relays), that control the plant. No
power cord is supplied because this power must be brought directly from its own circuit or fed from another
manual panel.
2.1.2 I/O Power and Manual Panel Same Phase Power
The CB-2 and manual panel will both be wired to the same I/O points for most plant controls (exceptions are air
compressors or other equipment the CB-2 doesn’t control in automatic mode). Because of this, it is critical that
the 120V “hot” that is used for the CB-2 I/O power, is the same “hot” phase used by the manual panel.
2.1.3 Unused Inputs Must be Jumpered to 120V
The CB-2 uses 120V input signals from various sensors for positive and negative feedback. At a minimum, the
CB-2 requires the following signals:
• Cement discharge gate closed (Terminal 4-13 - Rack 2, Point 7)
• Aggregate discharge gate closed (Terminal 4-15 - Rack 2, Point 8)
• Aggregate conveyor running (Terminal 4-9 - Rack 2, Point 5)
• E-Stop not pressed. This is fed 120VAC from inside the CB-2 automatic panel if 120V I/O power is
supplied.
If your plant is not equipped with any of these sensors, you must get 120VAC to these inputs to satisfy the CB-2
interlocks. The best place to get 120VAC is to jumper from terminals 6, 7, 8 on the top row of the main junction
block.

2.4 Digital I/O
Digital inputs can be set to provide many batching functions on the CB-2. Digital inputs are active low (0 VDC),
inactive high (5 VDC).
Digital outputs are typically used to co
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.
Table 2-5 shows the pin assignments for connector J2 which
Table 2-5. J2 Pin Assignments (Digital I/O) on CB-2 Main Board

3.0 Configuration of Scale Parameters
Note
The CB-2 is designed as a universal controller for all types of automated concrete production. There are many
settings and features that are only used by special applications. The factory default settings assume a two-scale
transit mix application and most of the default values will not need to be changed for this type of application. In
addition, system software has been pre-loaded along with a default database.
However, for the CB-2 to batch accurately, certain critical paramet
tuned (see tune plant section). As part of the default configuration, a minimum number of materials, physical
locations, and mix designs have been added. The mapping of the actual physical plant controls to the I/O points
in the software is also setup in the initial configuration.
To set up a standard configuration the
920i indicator, the indicator must be placed in setup mode. The setup
switch is accessed by removing the large fillister head screw on the back of the enclosure. Switch position is
changed by inserting a screwdriver into the access hole and pressing the switch.
When the indicator is placed in setup mode, a series of menus is shown
the words
Scale Configuration. The SCALES menu is highlighted as the first used to configure the indicator.
Detailed descriptions of these menus are provided in Section 3.2.
When configuration is complete, press the
Exit or Save and Exit softkey to exit setup mode, then replace the setup
switch access screw.
•The
Exit softkey exits setup mode without saving parameter changes to NV RAM. Changes made to the
configuration remain in the system until indicator power is cycled.
Save and Exit writes all parameter changes to NV RAM before returning to normal mode.
•
3.1 Configuration Methods
The 920i 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 3.1.2.
Configuration using the serial port can be accomplished using e
configuration utility.
Some configuration parameters, such as those used to configure the 920i display and widgets, cannot
be accessed through the configuration menus. iRev provides the most complete and efficient
configuration interface for the 920i.

The CB-2 has many parameters that must be configured in order for the unit to batch properly. Use the
configuration parameters mode to set values for parameters controlling system operation. Press the
softkey to access those configuration parameters which are listed in Figure 4-2.
Figure 4-1. Admin Menu Softkey Location
All of the Admin Menu parameters are listed below in the following flow chart to better help illustrate all of the
different parameter levels that must be set to ensure proper operation. To access each sub-parameter use the
down arrows on the 920i to scroll up or down through the various menu choices.

Target mode batching (default) will adjust the amount of each ingredient on a
scale based on the amount of the ones previously dispensed to come as
close as possible to the target number of yards/cubic meters.
Design mode batching will attempt to batch the design amount of a material
to come as close as possible to the mix design material proportions. Design
mode batching is currently unsupported.
Select Yes if trucks may be loaded that exceed the plant capacity. Trucks with
up to five times plant capacity may be loaded.
Select Yes to split the batches equally. Otherwise, all but the final batch will
be at plant capacity.
In an order based system, selecting Yes will cause the multiple loads of a
multi-load order to be run automatically one after the other until the order is
filled.
In a load based system, the same load will be run continuously until the Last
Batch softkey is pressed.
Count will prompt for a number of batches to run continuously.
Partial will prompt for a number of single batch units to run. The number can
include partial amounts and no batch will exceed a single unit. For instance, if
a mix design is specified that generates one yard and the operator keys in
1.6, the CB-2 will generate 1.6 yards of product in two 0.8 yard batches.
Likewise, if a mix design is specified that would generate two yards of material
and the operator enters 2.5 at the prompt, the CB-2 will determine that three
batches are required and generate five yards of product in three 1 2/3 yard
batches.
