WARNING

This manual is intended for use by service technicians responsible for installing and servicing the CB-2 and the end user who will be operating the CB-2 automated concrete batching system.

In this manual, you will see many references to the CB-2 and panel that includes Rice Lake’s 920i

HMI digital weight indicator. The 920i is the heart and brain of the CB-2

the 920i. To clarify, the CB-2 is a stand-alone batch

and is responsible for weight/scale data as well as running the CB-2 batching program. The CB-2 also contains additional hardware that is interfaced to the 920i. The majority of the additional hardware is for controlling the batch plant through digital I/O and then through solid-state 120V/240V relay modules.

Some procedures described in this manual require work inside the

losure. These procedures are to be

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

When in Normal Mode, the always show softkeys. The operator’s interaction 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 large portion of this manual is dedicated to explaining the categories and individual settings in the Admin Menu.

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

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 message “Up/Down nav keys are enabled” is displayed.

2. Press the down arrow key until scale 2 (the cement scale) is shown in the top weight widget and in the upper righthand corner of the display.

3. Press the zero key again. If the 920i allows the zero command, then the selected scale (scale 2, the cement scale), should now read zero. The CB-2 automatically puts the aggregate scale (scale #1) back in the top widget and redraws the text AGG, CEM, next to the appropriate weight widgets.

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.

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

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.

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.

Preact is used to account for material still in suspension after the filling is stopped. The amount in suspension will depend on the distance from the source to the top of the material already on the scale and that, in turn, is inversely proportional to the amount of weight on the scale – the more weight the less distance.

Front Water will add the admixture with the front water, Tail Water will add the admixture with the tail water, Discharge will add the admixture when the materials are added to the truck or mixer. Cement Discharge will start the admixture discharge when the cement discharge begins. Aggregate Discharge will start the admixture discharge when the aggregate discharge begins. Skiphoist Discharge will start the admixture discharge when the aggregate skiphoist discharge begins. Last will add the admixture after all other materials (except tailwater) have been added. Weighup will start the admixture discharge while the other materials are being weighed.

The 920i can be calibrated using the front panel, serial commands, or iRev. Each method consists of the following steps:

• Zero calibration

• Entering the test weight value

• Span calibration

• Optional five-point linearization

• Optional rezero calibration for test weights using hooks or chains

The following sections describe the

calibration procedure for each of the calibration methods.

Figure 5-1. Calibration (CALIBR) Submenu

5.1 Gravity Compensation

Gravity compensation for latitude and elevation is available for the 920i. To calibrate with gravity compensation, the LOCALE parameter under the FEATURE menu must be set ON, and the LATUDE (latitude) and ELEVAT (elevation, in meters) parameters set before calibrating the indicator.

If the indicator is later installed at a dif

ferent location, gravity compensation can be applied to a pre-calibrated

indicator by adjusting the LATUDE and ELEVAT parameters.

5.2 Front Panel Calibration

The CALIBR submenu (under the SCALES menu, see Figure 5-2) is used to calibrate the 920i The zero, span, and linear calibration point displays provide a set of softke

Figure 5-2. WZERO Calibration Display

40 Installation/Operation Manual

To calibrate the indicator using the front panel, do the following:

1. Place the indicator in setup mode (display reads

Scale Configuration) and remove all

weight from the scale platform. If your test weights require hooks or chains, place the hooks or chains on the scale for zero calibration.

2. With the SCALES menu highlighted, press the

down key, then select the scale to be

calibrated. Press

down again (GRADS

parameter highlighted), then press left to highlight the

CALIBR submenu (see

Figure 5-1). Press down to go to zero calibration (WZERO). See Figure 5-2 on page 40.

3. Ensure scale is empty, then press down again to show the current WZERO value, then press the Calibrate softkey to calibrate zero. When complete, the new A/D count for the zero calibration is displayed. Press

enter to save the

zero calibration value and go to the next prompt (

WVAL).

4. With WVAL displayed, press down to show the stored calibration weight value. Use the numeric keypad to enter the actual value of the calibration test weights, then press

enter to

save the value and go to span calibration

WSPAN).

(

5. Place test weights on scale. Press down again to show the current WSPAN value, then press the Calibrate softkey to calibrate span. When complete, the new A/D count for the span calibration is displayed. Press

enter again to

save the span calibration value and go to the next prompt (

WLIN).

6. Five-point linearization (using the WLIN parameter) provides increased scale accuracy by calibrating the indicator at up to five additional points between the zero and span calibrations.

Linearization is optional: if you choose not to perform linearization, skip the WLIN parameter; if linearization values have previously been entered, these values are reset to zero during calibration. To perform linearization, follow the procedure below:

With WLIN displayed, Press down to go to the first linearization point (POINT 1). Press down again to show the weight value prompt (WGT

), then down once more to show the weight

value. Place test weights on the scale, then use the numeric keypad to enter the actual test weight value. Press

enter to save the value and

move to the calibration (CAL 1) prompt. Press

enter again to save the calibration value

Press and go to the next prompt (

POINT 2).

Repeat for up to five linearization points. To exit the linearization parameters, press the up key to return to WLIN.

7. The optional rezero function is used to remove a calibration offset when hooks or chains are used to hang the test weights.

NOTE: The rezero function cannot be used with five-point linear calibration.

• If no other apparatus was used to hang the

test weights during calibration, remove the test weights and press

up to return to

the CALIBR submenu.

• If hooks or chains were used during

calibration, remove these and the test weights from the scale. With all weight removed, go to the REZERO parameter, then press value. Press the

down to show the current zero

Calibrate softkey to adjust

the zero and span calibration values. Press

enter or up to return to the CALIBR

submenu.

8. Press up to return to the SCALES menu, or press the Save and Exit softkey to exit setup mode.

5.3 Serial Command Calibration

To calibrate the indicator using serial commands, the indicator serial port must be connected to a terminal or personal computer. See serial port pin assignments.

Once the indicator is connected to the sending device, do the following:

1. Place the indicator in setup mode (display reads CONFIG) and remove all weight from the scale platform. If your test weights require hooks or chains, place the hooks or chains on the scale for zero calibration.

2. Send the SC.WZERO#n serial command (where n is the number of the scale) to calibrate zero.

3. Place test weights on the scale and use the SC.WVAL command to enter the test weight value in the following format:

SC.WVAL#n=vvvvv<CR>

4. Send the SC.WSPAN#n serial command to calibrate span.

5. Up to five linearization points can be calibrated between the zero and span calibration values. Use the following commands to set and

Section 2.3.1 on page 10 for

Installation/Operation Manual - Calibration 41

calibrate a single linearization point:

SC.WLIN#n.V1=vvvvv<CR> SC.WLIN#n.C1<CR>

The SC.WLIN#n.V1 command sets the test weight value (vvvvv) for linearization point 1. The SC.WLIN#n.C1 command calibrates the point. Repeat using the SC.WLIN#n.Vx and SC.WLIN#n.Cx commands as required for additional linearization points.

6. To remove an offset value, clear all weight from the

scale, including hooks or chains used to hang test weights, then send the SC.REZERO#n serial command.

7. Send the KSAVE serial command to s

ave the calibration changes; send KEXIT to exit setup mode.

5.4 iRev Calibration

The iRev Calibration Wizard provides step-by-step scale calibration. With the 920i connected to the PC, select the Calibration Wizard from the Tools menu on the

iRev Scales display, then follow the steps listed

below to calibrate the scale. See Section 5.0 on page 40 for a general overview of the

There are two basic modes of operation. The simplest is a load-based approach when the operator enters only a mix, truck, and load quantity. This method is best when the CB-2 is not used for generating billable tickets or tracking at the order level. In contrast, if order-based loading is selected, each order is entered in the CB-2 as the order is taken.

10.0 Appendix

The following sections go over additional parameters associated with the CB-2 and its functionality.

10.1 Configuration Parameters for the CB-2 Weighed Materials Discharged Using an Inch Gate

When configuring the CB-2 for inching gates it is important to know the time in seconds required to fully open and close the inching gate. Make sure the weigh hopper is completely empty before continuing. If possible, bins should contain material to assist with the accuracy of the required times.

Manually open the discharge gate and record the amount of time in seconds required to fully open the gate. Repeat a few times for accuracy. Average the time readings and this number will represent the “fully open time” for the gate. This process can be repeated to calculate the “fully closed time”.

Admin Menu

Database

Scales

Aggregate (OR) Cement

Inch Time

Duration in milliseconds (.001 second). Generally the “INCH TIME” time segment is calculated by dividing the “Fully Open Time” by 100. If the fully open time was 2 seconds (2000 milliseconds) / 100 the “INCH TIME” time segment would equal 20. The output relays that provide voltage to open and close the inching gate would be enabled for 20 millisecond intervals during flow rate adjustments. Dividing the “Fully open time” by 100 is an example that is often used. This number can be changed when applicable.

Initial Burst

Duration in seconds. Time that enables the open gate output relay when initially opening a gate. Keep in mind the “Fully Open Time” when selecting this value.

Control Rate Filter

Number of flow rate samples used to calculate rate adjustments. Sample rate is set at 100 per second. The number of samples selected will vary the time between flow rate adjustments. If the control rate filter is 100 there will be a 1 second interval between flow rate adjustments. If this value is set to 50 the flow rate adjustments will be done at .5 second interval.

Target Discharge Rate

Desired lb/kg discharge rate per second.

Discharge Rate Tolerance

Discharge rate within this tolerance % will not cause any flow rate adjustments.

Wide Open Weight

When the material weight left to discharge falls below this value the inching gate will open fully. This adjustment serves as a “clean out” action. The aggregate scale will not open fully even when the material weight falls below this value until the cement has totally discharged. In this situation, the aggregate gate will close until the cement is discharged and then open fully.

If this number is set too high material can over flow an aggregate belt if used. This parameter is applicable for a hopper type scale.

Close Time

Duration in seconds. This value equals the fully closed time. If the inching gate has no gate closed limit switch, this value will be used.

10.2 Configuration Parameters for CB-2 Weighed Materials Discharged Using an Open Close Gate

When configuring the CB-2 for an open close gate it is important to know the time in seconds required to fully open and close the gate. Manually open the discharge gate and record the amount of time in seconds required to fully open the gate. Repeat a few times for accuracy. Average the time readings and this number will represent the “fully open time” for the gate. This process can be repeated to calculate the “fully closed time”.

1000. The CB-2 will associate preact values 1 thru 10 with scale target values

0-1000 lb., 9001-10000 lb. The lowest hopper level (smallest batch siz

e) will be associated with the longest “material in flight” time requiring the largest preact value. The following example represents the association between preact weight band and possible preact levels.

PREACT WEIGHT BAND = 1000 (10,000 calibrated scale capacity / 10)

Targ e t Va l ue Preact Level Preact Level Value

0000 - 1000 1 550

1001 - 2000 2 500

2001 - 3000 3 450

3001 - 4000 4 400

4001 - 5000 5 350

5001 - 6000 6 300

8001 - 9000 9 150

9001 - 10000 10 100

Table 10-1. Preact Level Values

The preact level values will have to be determined for each material. Mix designs structured with one material only containing target values ranging from low to high ran automatically with jogging turned off will determine the preact level values. The amount over the target value should be entered for the appropriate preact level.

10.6 Changing the Location of a Material

Materials and their physical locations are defined under:

Admin Menu

Databases

Materials / Locations

Material Database:

Materials are identified by a material ID number and a name. Material type, material class, preacts and jogs are defined for each material as well as other miscellaneous parameters. The material ID number is what is used to identify the material in the “Ingredient” section of the mix design.

Location Database:

Locations are identified by a location number and name. The physical location of a material is defined here. “Material” is a parameter located in the database. The material number entered here will be associated with the delivery mode, digital outputs and setpoints structured to measure and discharge the required amount.

Concrete batching facilities may or may not have enough storage area for a material in one physical location. The ability to modify the location of a material can make the creation of mix designs much easier. One material number (name) can be used for all mixes by simply changing the physical location.

10.12 Moisture Specifications

10.12.1 Cement/Water/Aggregate Mix Specifications

When defining a mix, you specify the amount of cement, water, and aggregates per yard of delivered product. The specified amount of water is the amount needed to react with the cement (free water).

Aggregates may (and probably will) contain moisture (the moisture content of the cement and admixtures is ignored). They can contain both absorbed and free water. Absorbed water is NOT available to react with the cement – free water is.

Each material has an associated “Absorption Factor”. This is the maximum moisture level at which there is no free water. If a material is below its absorption factor, some of the added water will be absorbed by the material and will not be available to react with the cement. If it is above its absorption factor, some of the water in the aggregate will be available.

The CB2 will automatically adjust added water based on the current moisture levels in the aggregates, either adding or subtracting as needed.

10.12.2 Oven Dry vs. Saturated Surface Dry Mix Designs

When specifying a mix design, the amount (by weight) of an aggregate per yard of delivered product is specified. For a particular batch, the amount by weight is dependent on how much moisture is present, This may change from day to day, but we don’t want to have to continuously change our mix designs to account for these differences.

To solve this problem, we specify mix designs in terms of material with a specified moisture content and then adjust that weight based on the current moisture content when producing product.

There are two recognized standard moisture levels – Oven Dry (OD) and Saturated Surface Dry (SSD). Oven Dry contains no moisture at all. Saturated Surface Dry Contains moisture at the material’s “Absorption Level”. Mix designs may specify the amount of aggregate per yard in either Oven Dry or Saturated Surface Dry weights. (Right now, the only way to use Oven Dry weights is to specify Minnesota DOT as the regulatory agency.)

10.12.3 Example of Weight Adjustments Based on a Saturated Surface Dry Mix Design

This example shows how the CB2 adjusts the designed aggregate and water amounts based on actual moisture content for a mix design using SSD aggregate weights.

Suppose for simplicity’s sake we have a design that calls for 1000 pounds of gravel, 500 pounds of cement, and 400 pounds of water per yard of concrete. Suppose also that the gravel has an absorption factor of 6% and a current moisture content of 4%.

As the design is based on SSD weights, we could use the specified weights if the current moisture level was 6% the same as the absorption factor - but it is not – we are 2% short. So, how much gravel would we need to add at 4% moisture content to get the same amount of oven dry gravel as 1000 pounds of SSD gravel?

1000 pounds of SSD gravel contains 943 pounds of OD gravel (1000 / (100 x (1 + .06)). 943 pounds of OD gravel at 4% moisture is 981 pounds. (943 x 1.04). So, to get the same amount of gravel, we need to reduce the 1000 pounds per yard to 981 pounds per yard.

OK, but we are not finished. When we add water to the mix, the aggregate will absorb enough of it to bring its moisture content up to the SSD level. This water is not available to chemically react with the cement, but, because the mix design is SSD based, the amount of water specified to be added is what is needed for this reaction. We need to adjust the amount of water to be added to account for this.

Actually, this is pretty simple. We know that at SSD, the aggregate is 1000 pounds per yard and that we are adding aggregate at 981 pounds per yard, so how much extra water do we need to bring it up to its 1000 pounds per yard? 19 pounds per yard (1000 – 981).

So, for this simple case we wind up with an actual batch calling for 981 pounds per yard of gravel, 500 of cement, and 419 of water.

Installation/Operation Manual - Appendix 77

10.12.4 Calculating Aggregate Moisture Content

Moisture content is specified as the percentage by weight of moisture in a sample relative to the totally dry weight of the same sample. To determine this percentage, weigh the sample (Mw), totally dry it and weigh it again (Md). The moisture content in percent is then:

((Mw – Md) x 100)/Md

10.12.5 Specifying Moisture Content and Absorption Factors

The absorption factor for an aggregate is a constant for that material and is specified in the material definition process for the aggregate. The value is specified in percent using the “Absorbed Moisture” parameter in the material database.

The moisture content for a particular aggregate may change from day to day and is initially specified in the location (bin) definition process for the bin holding the aggregate. The value is specified in percent using the "Total Moisture" parameter in the location database.

The current moisture content for an aggregate may be changed before batching a load or order using the “Aggregate Moisture” item under the "EZ-Change Criticals" feature. This change will be permanent.

10.12.6 Calibrating a Moisture Probe

Moisture probes should be calibrated to the material being monitored. You will need two samples of the material, both at known moisture contents. For accuracy, they should be as far apart as possible (oven dry and saturated surface would be ideal). Specify the low end content level in percent (ie: 8.6% = 8.6), place the probe in the material, wait for the reading to stabilize, and calibrate the reading. Repeat at the high end.

Specify the high end moisture content, place the probe in the second sample, wait for the reading to stabilize, and calibrate the reading.

10.14 Tuning Inching Gates

There are four controls used in the CB-2 to tune inching gates which include three CB-2 application variables and the 920i filtering variable.

The three CB-2 variables are the control rate filter in the scales database and the initial burst time and inch time parameters found in the scales database for hopper scales or the locations database for loss in weight scales.

Initial Burst Time Parameter

Indicates the duration in seconds of the initial open signal. Adjust this to control how far the gate is initially opened.

Inch Time Parameter

This indicates the duration in milliseconds (0.001 seconds) of the inching pulses.

Control Rate Filter

This specifies the time in milliseconds (0.001 seconds) both to wait for the flow rate to stabilize after moving the gate and over which to measure the flow rate once it has stabilized.

The CB-2 will wait for this amount of time for the flow rate to stabilize after pulsing an inching gate and then average the rate for the same amount of time to determine the next action to take.

The 920i indicator variables are the filtering parameters.

The rate of change calculation is based on filtered weight readings, so higher filtering settings will result in slower response to sudden flow rate changes.
