MISCELLANEOUS COMPONENTS

RAM TOUGH HUBUSB distribution point for the system. Provides connections to the USB-CAN adapter, camera adapter, AVL Adapter, and the USB data port below the Operator Switch Module.

USB CAN ADAPTERProvides a communication bridge between the tablet and the CAN bus.

DC-DC CONVERTERProvides regulated 5V power to the tablet.

KEYBOARDA keyboard is required to program and calibrate the system. The keyboard has been environmentally hardened for use in the ice control field. After programming and calibration, the keyboard is disconnected and stored.

GROUND SPEED SENSORThe ground speed sensor generates vehicle speed information for the console. Sensor electrical pulses proportional to the vehicle ground speed are vital to system operation because true vehicle ground speed is necessary for accurate product application. The system can function with a variety of electronic and mechanical speedometer sensors, such as hall effect and reluctance sensors.



OPERATOR’S MANUAL

ROAD TEMPERATURE ADAPTER (OPTIONAL)Temperature sensors allow for direct readout of road temperature and ambient air temperature.

FEEDBACK/APPLICATION RATE SENSOR (OPTIONAL)Feedback sensors send product flow information to the console for accurate product application. Both granular and spinner channels require pulsed electrical sensors having an output proportional to the mechanism speed. The liquid channel accepts either electrical-pulsed sensors or analog sensors with outputs proportional to material flow (pulsed). A liquid prewetting system only accepts pulsed feedback while higher capacity anti-icing systems accept either pulsed or analog.

GATE HEIGHT SENSORS (OPTIONAL)Measures gate height setting in inches and automatically adjusts conveyor speed to compensate for gate height changes and maintain application rate.

HYDRAULIC PRESSURE SENSORS (OPTIONAL)Hydraulic pressure sensors measure the amount of down pressure applied on the underbody scraper.

FLOW METERSFlow meter measures the flow rate of material being applied.

VALVE CONTROL OUTPUTFlex4 rate controllers control PWM hydraulic and Servo valve electric motors that regulate material flow for accurate control of product application rates. Granular and spinner channels regulate the hydraulic oil flow rate to a motor. Liquid channels use various different configurations such as servo ball valves and electric pumps.

HARNESSESHarnesses are included that are required for communication between the console and components. Optional extension harnesses are available for the Rate Control Module harness and output module harness when mounted in areas where additional harnessing is required. Electric motor driver harness is also available.

HOPPER LEVEL SENSOR (OPTIONAL)A hopper level sensor can be used to trigger an alarm when material falls below the sensor mounting level.

VIDEO CAMERA (OPTIONAL)Multiple cameras can be installed in order to monitor dispensed material or provide aid in backing the vehicle.

GRANULAR RATE SETUP

MATERIAL LABELA user-defined material name entered (10 characters maximum) that identifies the material configured for a channel on the Operate screen.

UNITSUnit of measure for granular material are available in the following parameters:

– lbs (kilograms) per mile (km)– lb/mi ft (g/km-m)– lbs per sq ft/grams per sq meter– lbs per sq yd/meter– lbs/kft2 (Kg/m2)– lbs per acre (Kg/Ha)

SPREADER CONSTANTRepresents the number of pulses generated by the application rate sensor per pound of material (P/LB or P/KG) discharged from the spreader. The spreader constant varies for each granular material, spreader vehicle, and gate height setting (if optional gate height sensor is installed and enabled).

If the spreader constant is known, the value can be manually entered via a keyboard with no granular calibration required. For unknown spreader constant values, a granular calibration should be performed.

CALIBRATION GATE HEIGHTCalibration Gate Height displays only if the gate height sensor is enabled at the Accessory Sensor screen (F9). If enabled, the calibration gate height value displayed is the setting of the gate height (inches) as a result of a performed spreader calibration.

IMPORTANT: The Gate Height must be enabled before a spreader calibration is performed. Refer to the Spreader Calibration procedure.

The original calibrated gate setting can be changed to provide a more accurate granular material application by adjusting the conveyor speed.

– An increased gate height decreases conveyor speed– A decreased gate height increases conveyor speed

If the sensor voltage is outside the range between the Closed and Open position values, the display states Gate Low or Gate High. If Gate Low displays, the signal from the sensor is exceeding the open voltage. In either case, an alarm activates. The Gate Height should be checked and set at the granular calibration it was ran for on that granular channel.



OPERATOR’S MANUAL

APPLICATION RATE METHOD Two methods are available to control material application:

• Step Method• Rate Method

Step MethodAllows rates to be changed by a fixed increment using the Rate Increase/Decrease buttons on the switch module.

NOTE: Rate changes only occur when the material is selected/highlighted on the Operate screen.

1. Highlight the Step method selection box and press the Enter key on the keyboard.

2. Select Yes and press the Enter key again. 3. Enter the desired target rate (lbs/mile) for material application to be

controlled by this channel.4. Enter a minimum application rate limit for this channel. Minimum rate

establishes the minimum application rate that the control allows. Target rate cannot be decremented to a value lower than this established Min Rate.

5. Enter a maximum application rate limit for this channel. Maximum rate establishes the maximum application rate that the control allows. Target rate cannot be incremented to a value greater than this established Max Rate.

6. Enter an Increase/Decrease Step value that sets the increase/decrease rate. The increment/decrement percent rate establishes the percentage of change of the entered target rate that is applied each time the Rate Increase/Decrease button is pressed.

NOTE: The maximum or minimum rates may not be reached if the % increase or decrease, based off the target rate, exceeds the maximum or minimum rate limits set.

7. Enter a desired blast rate that applies a higher-than-normal, spot application when the Blast button is pressed during operation.

CALIBRATIONS

Spreader trucks have a variety of material delivery systems and various combinations of hydraulic/liquid pumps, valves, and motors. It is important that calibrations of the system and control channels are performed to define configuration characteristics and ensure optimum performance.

Two calibration types are recommended prior to operation:

1. Material and Spinner System Response Calibrations2. Drop Test Calibration

IMPORTANT: Performing the following procedures in the order outlined ensures the greatest accuracy.

MATERIAL AND SPINNER SYSTEM RESPONSE CALIBRATIONS (F6)A system response calibration adjusts the response time of the system to the installed hydraulic and mechanical systems. Performing this calibration determines the system response and related constants, such as Valve Boost, PWM Offset, and AFILT, for each of the control channels.

Constants may vary slightly each time a system response calibration is performed. Manual fine tuning for optimum performance is acceptable.

IMPORTANT: During calibrations, the truck must be running and the RPM’s should be within the truck’s normal operating range.

GRANULAR RESPONSE CALIBRATIONDuring calibration, a set of values for System Response, Valve Boost, PWM Offset, and AFILT automatically calculate, store, and display on the Granular Configuration screens for all granular materials.

NOTE: Liquid pre-wet and liquid anti-ice channel setup follows same steps as granular. Refer to page 105 for Drop Test and Calibration procedures.

To perform a Granular System Response Calibration:1. At the System Calibration screen (F6), select (1) Granular System

Response. A warning screen indicates this test activates the channel and material will dispense.

2. Press “R” to begin test. A series of steps display on the screen during calculations. When finished, the System Response Done screen displays.

3. When the calibration is complete the results automatically record in the proper locations. Press “C” to automatically begin drop test or press “D” to return to the Calibration screen.


CALIBRATIONS / 103

OPERATOR’S MANUAL

Figure 94System Response Calibrat ion Screens

NOTE: Liquid pre-wet and anti-ice channels have similar calibration steps as granular.

RECORDING CALIBRATION DATAAfter performing each calibration, record the calibration constants on the Calibration Data Record sheets included with this manual. If console replacement is necessary, export system files to a USB memory device for import to another system.


104 / CALIBRATIONS

OPERATOR’S MANUAL

MAINTAINING CALIBRATION ACCURACYCalibration accuracy can be affected by various conditions and to retain optimum performance a system calibration should be performed for the following conditions:

• If a new material is added and the spreader, nozzle, or flow meter constant is not accurately known, perform a granular or liquid calibration routine.

• If wear of the conveyor/auger mechanism, actuator valves, flow meter, nozzles, or other system components is suspected, perform a new catch test (granular or liquid calibration) to re-establish APR accuracy.

• Perform a ground speed calibration after installing new or different tires.

• Each known physical (mechanical) change in the system should be followed immediately by a system response calibration on the related control channel (granular, liquid pre-wet, liquid anti-ice, or spinner).

• A periodic system recalibration when repair or replacement has occurred on any system components, including hydraulic hoses, fluid changes, and normal wear.

• A yearly system calibration of all control channels at the beginning of each spreader season.

SYSTEM RESPONSE ADJUSTMENTSAdjustments after a system calibration can be made so the system responds faster or slower than calculated by the automatic calibration routines.

Automatic calibration routines should always be performed prior to modification to establish basic values.

System performance can be improved by adjusting the following functions:

SYSTEM RESPONSE CONSTANT• Control system responds slowly in speed and is slow to start

– Increase the system response value• System oscillates around the target APR

– Decrease the system response value

Excessive oscillation should be limited to +/-5% of the target APR to minimize wear on the PWM valve. Most systems can be tuned by altering only this value.

VALVE BOOSTValve Boost increases system response only at startup to quickly start system spreading. The value does not affect stability when operating at the target APR and does not normally require adjustment.


CALIBRATIONS / 105

OPERATOR’S MANUAL

AFILTNoisy feedback sensors cause the APR’s to randomly jump. AFILT value indicates the amount of feedback noise rejection. The smaller the number, the greater the filtering. Decreasing the AFILT can reduce the problem but also can cause the system to become more sluggish. Typically this value does not require adjustment.

GRANULAR DROP TEST CALIBRATION The Drop Test determines the spreader constant for a given granular material. The spreader constant is the number of pulses generated by the application rate sensor per pound of granular material discharged. A separate calibration routine must be run for each granular material used.

During a calibration the control system runs the conveyor/auger mechanism dispensing material while the vehicle is stationary. When a sufficient amount of material has been discharged, the operator stops the spreader mechanism, weighs the material discharged, and enters the amount at the Calibration screen. The system then calculates, stores, and displays the spreader constant.

DROP TEST PREPARATION1. Load the vehicle hopper with the desired material and verify the gate

height is adjusted to the proper setting on the V-Box spreader. If tailgate spreads are in use, ensure auger is full.

2. Load enough material to provide a uniform flow throughout the calibration procedure.

3. Position a suitable container or drop cloth to catch all dispensed material from the conveyor/auger. The container must be large enough to obtain a good, representative sample. The larger the sample weighed, the better the accuracy. Alternatively, if a vehicle scale is available, weigh the truck before and after dispensing material.

4. System is ready for calibration drop test.

PERFORMING A GRANULAR DROP TEST

NOTE: Steps 1 and 2 are performed when a granular drop test is initiated from the F6 Calibration screen.

1. At the System Calibration screen (F6), select the Granular Drop Test and follow the onscreen instructions.

2. At the Granular Calibration screen, select and press the corresponding number (1-4) of the appropriate material.

A warning message indicates material will dispense when the procedure is started. Ensure all personnel are clear before starting the next step.

IMPORTANT: If a gate height sensor is installed, verify the gate height sensor selection is enabled at the (F9) Accessory Sensor screen before performing the drop test.


106 / CALIBRATIONS

OPERATOR’S MANUAL

NOTE: Calibration Data Sheets are available in back of this manual to record constants.

3. With the vehicle stationary, engage the hydraulic system. 4. Increase engine RPMs to normal operating range.5. Press “R” to begin test and to run the conveyor/auger. Several steps

display during calculations before the System Response Done screen appears. The number in the middle of the screen shows the counts accumulating from the APR sensor. If a count is not recorded and stays on “0”, stop the test and check the application rate sensor.

6. When a sufficient amount of material has dispensed, press “S” to stop the system. A screen appears indicating the previous spreader constant and the sensor counts accumulated during the current run.

7. Perform the next step while the screen waits for the results.8. If using a vehicle scale, reweigh the truck and calculate the amount of

material dispensed in pounds.9. Enter that number into the console and press “D” when finished. The

new spreader constant is now stored and displayed on the calibration screen and on the appropriate configuration screen for this material.

10. For maximum accuracy, repeat the entire procedure at least three times.

11. Average the results and enter the average as the final spreader constant.

12. Record the material’s spreader constants on the Calibration Data Records sheets at the rear of this manual.

13. Repeat this procedure for each granular material used.

OPERATOR’S MANUAL

NOTE: Pressing “S” stops the calibration and values default to the original settings.

GRANULAR CALIBRATION ADJUSTMENTSIf small but consistent application rate errors are observed over a period of time, the spreader constant can be modified to improve application accuracy. Refer to Appendix B for steps to re-calculate a new spreader constant. This constant can be manually entered on the Granular Configuration screen. A granular calibration routine can also be repeated to correct this type of APR error.

LIQUID DROP TEST CALIBRATION (F6)A Liquid Drop Test Calibration determines a flow meter constant (K Factor) for each liquid material used. The K Factor represents the number of pulses generated by the flow meter per gallon of liquid dispensed. The nozzle constant is a measure of flow rate through the nozzle at a standard pressure. Separate calibrations are necessary for each liquid material because of viscosity differences.

The liquid drop test routine causes the control system to run the liquid pump dispensing material while the vehicle is stationary. When a sufficient amount of liquid has been discharged, the system is stopped and the discharged liquid weighed, and the amount entered at the Calibration screen. The system then calculates, stores, and displays the K Factor.

DROP TEST PREPARATION1. Load vehicle tank with material.2. Position a suitable container to catch all the material dispensed

through the liquid pump. The container must be large enough to obtain a good, representative sample. The larger the sample weighed, the higher degree of accuracy. When calibrating a pre-wet liquid material, the pre-wet bar can be removed from its mounting and placed inside the catch container. Alternatively, especially for flow meter and anti-ice liquid materials, temporarily disconnect an appropriate hose and place inside the catch container.

3. System is ready for calibration drop test.4.

NOTE: Calibration Data Sheets are available in back of this manual to record constants.

A warning message indicates material will dispense when procedure is started. Ensure all personnel are clear before starting the next step.

PERFORMING A LIQUID DROP TEST

NOTE: Steps 1 and 2 are performed when a granular drop test is initiated from the F6 Calibration screen.

1. At the System Calibration screen (F6), select the Liquid Drop Test and follow the onscreen instructions.

2. At the Liquid Calibration screen, select and press the corresponding number (1-4) of the appropriate material.– For pressure-based anti-ice systems, a target pressure must be

entered. This should be the nozzle manufacturer’s rating pressure typically 40 psi (2.75 bar).

MATERIALTarget RateTarget Rate displays the defined application rate set at the configuration screen and the rate the Diagnostics screen will perform the test.

– Target rate can be adjusted at the Operate screen by pressing the Increase/Decrease Rate buttons on the switch module to achieve the desired target rate.

Actual RateActual rate is the rate that is being applied during the test. The Actual Rate should match or run closely to the Target Rate.

– A wrong actual rate could indicate that a system response should be performed or a faulty feedback sensor.

Set PointSet Point, displayed in hertz, is the pulses per second required for the feedback sensor to achieve the target rate at the manual ground speed set.

– No set point could indicate a configuration issue or faulty master module.

Filtered FeedbackFiltered Feedback is the actual pulses per second of the feedback sensor and indicates the PWM signal being sent to the hydraulic control valve.

– No filtered feedback could indicate a faulty feedback sensor.

Pulse CountPulse Count reading indicates pulses sent from the feedback sensor to the rate control module.

Output PWMOutput PWM indicates the current PWM signal and continues to increase until the desired target rate is reached and then should remain steady when achieved.

RPMRPM indicates the revolutions per minute of the conveyor/auger.

Ground Speed FrequencyGround Speed Frequency identifies the pulses per second coming into the control module and could indicate a potential problem with the module, not reading a signal from the sensor, or a speed sensor failure.

222 Valve Calibration Abort Alarm

Control channel valve calibration has been aborted due to an error.

Try calibration again.

206 “Channel” Auto Open (In Manual Control)

A manual override state occurs when an application rate sensor or flow meter fails. Manual override allows material to be spread at the same programmed rate without interruption. When a failure occurs, the rate decreases to “0” and “Manual” replaces the material name. Rate returns from “0” back to target rate while manual override is enabled. Material may be over or under applied in this mode.

Check feedback sensors, i.e., application rate sensors and flow meters.

208 “Channel” Application Rate error (granular)

APPENDIX B CONVERTING CONSTANTS

FINE TUNING APPLICATION

Adjusting Granular ConstantsIf small (less than 10%) but consistent granular APR errors (either high or low) are observed over a period of time, fine tuning of the system can be performed by adjusting the value of the spreader constant by the same percentage as follows:

EXAMPLE: If SPR CON is 100 and Target APR is 300 LBS/MILE but Actual APR is known to be 315 LBS/MILE, adjust SPR CON using the above formula:

NOTE: Keyboard enter the new SPR CON on the appropriate (Granular) configuration screen.

Adjusting Liquid ConstantsIn a manner similar to that for granular (shown above,), liquid APR errors can be corrected by fine tuning the flowmeter constant (K-FACTOR) as follows:

EXAMPLE: If K-FACTOR is 1,000 and Target APR is 10 GAL/MILE, but Actual APR is known to be 9.5 GAL/MILE, adjust K-FACTOR using the above formula:

New SPR CON = Old SPR CON x Target APRActual APR

New SPR CON = 100 x = 95.2 300315

New K-FACTOR = Old K-FACTOR x Target APRActual APR

New K-FACTOR = 1000 x = 1053 109.5


APPENDIX B CONVERTING CONSTANTS / 147

OPERATOR’S MANUAL

CALCULATING SPREADER CONSTANTSThe spreader constant can be calculated if the following is known:

A = Number of pulses per revolution of the sensor shaft.B = Turns of the sensor shaft for each turn of the final shaft.C = Pounds of material discharged per revolution of the final shaft.

EXAMPLE:

A = 360 pulses per revolution (for Dj sensor p/n 46436-017X).B = 25 turns of the sensor shaft for each turn of the final shaft.C = 50 pounds of material discharged per revolution of final shaft.

NOTES:

1. V-Box spreaders have a different SPR CON for each gate setting.2. The number of pulses per revolution for several Dj shaft sensors are:

360 for p/n 46436-017X (standard DICKEY-john shaft sensor).60 for p/n 10844-000X180 for p/n 464361500S1

SPR CON = Pulses Per PoundA x BC

SPR CON = = 180 P/LB 360 x 2550
