MISCELLANEOUS COMPONENTS KEYBOARD A 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 SENSOR The 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. ROAD TEMPERATURE ADAPTER (OPTIONAL) Temperature sensors allow for direct readout of road temperature and ambient air temperature. 12 / COMPONENT OVERVIEW

19 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 capactiy 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 METERS Flow meter measures the flow rate of material being applied. VALVE CONTROL OUTPUT Flex4 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. HARNESSES Harnesses 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. GPS RECEIVER (OPTIONAL) A GPS receiver for vehicle tracking. VIDEO CAMERA (OPTIONAL) A video camera installed on the rear of truck allows viewing of material dispensing and aids in backing the vehicle. COMPONENT OVERVIEW / 13

UNITS Unit of measure for granular material are available in the following parameters: lbs (kilograms) per mile (km) lb/mift (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 CONSTANT Represents 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 HEIGHT Calibration 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. 52 / SYSTEM PROGRAMMING

105 CALIBRATIONS NOTE: Liquid pre-wet and liquid anti-ice channel setup follows same steps as granular. Refer to page 94 for Drop Test and Calibration procedures. 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 Calibrations 2. 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 CALIBRATION During 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. 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 / 99

RECORDING CALIBRATION DATA After 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. 100 / CALIBRATIONS

107 MAINTAINING CALIBRATION ACCURACY Calibration 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 ADJUSTMENTS Adjustments 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 BOOST Valve 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 / 101

108 NOTE: Steps 1 and 2 are performed when a granular drop test is initiated from the F6 Calibration screen. AFILT Noisy 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 PREPARATION 1. 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 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. 102 / CALIBRATIONS

109 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. CALIBRATIONS / 103

111 NOTE: NOTE: Pressing S stops the calibration and values default to the original settings. Calibration Data Sheets are available in back of this manual to record constants. GRANULAR CALIBRATION ADJUSTMENTS If 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 A 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 PREPARATION 1. 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. A warning message indicates material will dispense when procedure is started. Ensure all personnel are clear before starting the next step. NOTE: Steps 1 and 2 are performed when a granular drop test is initiated from the F6 Calibration screen. PERFORMING A LIQUID DROP TEST 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). If running pressure, ensure booms are drained prior to running Offset CALIBRATIONS / 105

112 A warning message displays indicating that material will dispense when channel is activated. Ensure all personnel are clear before starting the next step. 3. When ONLY the liquid channel is propelled by the hydraulic system, start the engine keeping the vehicle stationary. 4. Engage the hydraulic system and increase the engine RPMs to normal operating range. 5. Press R to run the liquid pump and start the calibration routine. For flow meter based systems, use the Rate Increase/Decrease buttons on the switch module to obtain an adequate discharge rate. The number displayed indicates the accumulating count from the APR sensor. 6. When a sufficient amount of liquid has dispensed, press S to stop. For a flow meter-based system, a screen appears showing the previous K Factor and the sensor counts accumulated during the current run. For a pressure-based system, the previous nozzle constant and collection time display. The screen asks for an entry of gallons before proceeding. 7. Perform the next step while the screen waits for the results. 8. Weigh the material caught and calculate the amount dispensed in gallons. 9. Enter the number into the console and press Enter. IMPORTANT: The amount dispensed value must be entered to adjust the K Factor value; otherwise the K Factor will remain at the current setting. 10. Press D when finished. The flow meter constant is now stored and displayed on this screen and on the Liquid Configuration screen for this material. 11. For maximum accuracy, repeat the entire procedure at least three times. 12. Average the results and enter the average as the final K Factor constant. 13. Record the material s K Factor constants on the Calibration Data Records sheets at the rear of this manual. 14. Repeat this procedure for each liquid material used. 106 / CALIBRATIONS

118 GROUND SPEED CONFIGURATION (F8) Ground speed configuration sets the parameters for ground speed type and performs a calibration. Figure 99 Ground Speed Configuration GROUND SPEED SOURCE CAN Used when ground speed is provided by a radar/digital (3-wire) type sensor connected to the cab harness or if radar/forward ground speed is communicated on the CAN bus. DIGITAL Used when ground speed is provided by a radar/digital (3-wire) type sensor connected to the actuator harness. RELUCTANCE Used when ground speed is provided by a reluctance (2-wire) type sensor connected to the actuator harness through an adapter harness. MAXIMUM CONTROL SPEED Indicates the allowed maximum speed in AUTO mode before a Maximum Speed Exceeded warning occurs. The value entered is based on the highest speed for acceptable system performance. If a zero is entered, the function is disabled. MANUAL SPEED ON Manual Speed On overrides the current system when the ground speed sensor is not operating properly. An internally-generated ground speed signal allows for continued operation and can also be used for testing, troubleshooting, or calibrating the vehicle while stationary. MANUAL SPEED ACCESS Allows the operator to activate the manual speed mode when necessary. Manual speed can be enabled and disabled at the Material Selection screen. 112 / CALIBRATIONS

119 MAXIMUM MANUAL SPEED Sets the maximum manual ground speed allowed to spread the target APR. MANUAL SPEED Represents the ground speed in miles per hour with an artificial, internally-generated signal. Vehicle speed should run close to the maximum manual speed to ensure materials are spread to the target APR. CONTROL STARTUP SPEED The speed the system begins to operate when ground speed sensor pulses start. Until this threshold is crossed, the startup ground speed signal is used. CONTROL SHUTOFF SPEED Minimum ground speed allowed before the system stops operation. It is recommended that shutoff speed be set at 0.0 unless speed appears from a mechanical sensor. GROUND SPEED CONSTANT Determines the number of pulses received from the ground speed sensor per mile of travel. If unknown, the value automatically calculates during a ground speed calibration. CALIBRATIONS / 113

120 GROUND SPEED CALIBRATION (F8) Ground speed calibration establishes a ground speed constant(s) for the vehicle. The constant is determined by counting the number of ground speed sensor pulses generated in a distance of one mile. Figure 100 Ground Speed Calibration Screens 114 / CALIBRATIONS

121 NOTE: For better accuracy, it is recommended to slow down at the second marker so reaction time is better when pressing S to stop. To establish a Ground Speed Constant: 1. Accurately measure one mile marking the start and finish points. Markers should be visible from the cab while driving past. Alternatively, two highway mileage markers can be used. 2. At the Ground Speed Calibration screen (F8), press C to begin calibration. 3. Drive to the start of the course at a minimum speed of 5 mph (8Km/hr). 4. When even with the start marker, press S on the keyboard. The calibration begins as the vehicle is moving. 5. Drive at normal operating speed. 6. At the finish marker, press C to complete the calibration. 7. Press S to save the value, press R to restart the calibration or press Esc to abort the calibration. 8. To ensure accuracy, repeat the calibration procedure three times and average the results. Enter the average value. 9. Record the ground speed constant on the Calibration Data Records sheets at the rear of this manual. CALIBRATIONS / 115
