4.1.3 PAIRING THE REMOTE The remote should arrive ready for the customer to use, but if it becomes unpaired from the receiver or a replacement remote is purchased, it is necessary to register the remote with the receiver. 1. Switch OFF or DISCONNECT the power to the receiver. 2. Switch ON or reconnect the power to the receiver. This opens a 20 second registration window in the receiver. If you are looking at the receiver circuit board, the fault LED flashes. 3.
4.1.
4.2 FILL AUGER Figure 4 DANGER! Use extreme caution when moving the auger, especially near power lines. It is not necessary to come into direct contact with an overhead power line for electrocution to occur. Serious injury or death will result WARNING! Keep arms, hands and legs away from auger intake. Wear appropriate fitting clothing when working in the vicinity of an auger. Keep all guards and shield in place and inspect to ensure they are properly attached and intact.
4.2.1 POSITIONING THE AUGER NOTE: Ensure that the area in the vicinity of auger operation is free of obstructions and that all bystanders, especially children, are kept at a safe distance before positioning or operating the auger. 1. Ensure your tractor circuit is engaged in the correct direction prior to engaging the auger diverter valve. If circuit is already engaged direct the fan diverter valve to the fill auger position from the fan location, Figure 5.
4.2.2 OPERATING THE AUGER 1. Ensure that all screens and shrouds are in place and that the cleanout gate, on the bottom of each meter, is closed, Figure 8. 2. Activate tractor hydraulic circuit #4, and pull the diverter valve up to the auger circuit. 3. The handle on the auger tube is the control to operate the auger flighting in a forward or reverse direction. Figure 8 4.
4.2.4 AUGER TRANSPORT POSITON NOTE: Fill auger should always be secured for transport, no matter how short the distance. Clean out auger prior to transport or storage. 1. Position the auger so that the tube is resting on the locking mechanism at the back of the aircart. In TBH configurations only, the hopper can be rotated down for transport, Figure 10. Figure 10 2. The locking mechanism must be used to secure auger when transporting at all times, Figure 11. 3.
4.3 FILL CONVEYOR Figure 13 DANGER! Use extreme caution when moving the conveyor, especially near power lines. It is not necessary to come into direct contact with an overhead power line for electrocution to occur. Serious injury or death will result WARNING! Keep arms, hands and legs away from conveyor intake. Wear appropriate fitting clothing when working in the vicinity of a conveyor. Keep all guards and shield in place and inspect to ensure they are properly attached and intact.
4.3.1 POSITIONING THE CONVEYOR NOTE: Ensure that the area in the vicinity of conveyor operation is free of obstructions and that all bystanders, especially children, are kept at a safe distance before positioning or operating the conveyor. 1. Ensure your tractor circuit is engaged in the correct direction prior to engaging the conveyor diverter valve. If circuit is already engaged, direct the fan diverter valve to the conveyor position from the fan setting.
4.3.2 OPERATING THE CONVEYOR 1. Ensure that all screens and shrouds are in place and that cleanout gate on each meter is closed, Figure 17. 2. Activate tractor hydraulic circuit #4, and pull the diverter valve up to the auger circuit. 3. Use either of the buttons located at the top and bottom of the conveyor to start and stop the conveyor, Figure 18. Figure 17 4. Whether filling or unloading the aircart, the auger performs at its highest capacity when product is falling directly into the flighting.
4.3.4 CONVEYOR TRANSPORT POSITION NOTE: Fill conveyor should always be secured for transport, no matter how short the distance. Clean out conveyor prior to transport or storage. 1. Latch down the conveyor hopper then fold it up on top of the conveyor tube. Be sure to secure it with the tie down strap supplied. Figure 20 2. Arrange the conveyor so that the upper rest is positioned on the conveyor saddle at the front of the aircart, Figure 20. 3.
4.4 BAG LIFT If equipped, the optional bag lift can be used for transporting bagged agricultural product from the ground to the top of the air cart. The bag lift has a maximum capacity of 550 lbs or ten bags of canola (50lb bags). The bag lift runs off the same hydraulic circuit as the auger or conveyor. To operate the bag lift the diverter valve must be switched to the auger or conveyor setting.
4.5 CASE DRAIN LINES You must also connect the case drain lines (two 1/2” hoses, one with a yellow band) to return hydraulic fluid back to the tractor reservoir. One case drain line is a 1/2” (13 mm) line from the fan. The other case drain line is a 1/2” (13 mm) line from the hydraulic manifold. The case drain line(s) MUST return to the tractor UNRESTRICTED. Failure to do so can cause damage to the hydraulic cylinders or fan motor and will void manufacturer’s warranty. Seed Hawk Inc.

4.7 METERING ROLLER The metering roller, Figure 25, is provided in each compartment. There are four different roller section types: canola, helical, straight fluted (bean) and chick pea. However, the canola roller is only available on hydraulic drive equipped aircart models. The helical roller section is designed to accommodate the majority of seeding products including small oil seeds, cereals, and granular fertilizer. The straight fluted (bean) roller is used for small pulses and granular fertilizer.
4.7.
4.8 SEED HAWK® PRESSURIZED METERING SYSTEM Figure 27 With the Seed Hawk® pressurized metering system product can be diverted to either air stream, Figure 27. This gives the Aircart ultimate flexibility by allowing the option of diverting any product to either the seed knife or the fertilizer knife. To change the air stream that a meter will deliver product to, adjust the diverter valve on the side of the meter body, Figure 28.
4.9 FAN(S) Connect the pair of 3/4” hydraulic lines (Fan one has a blue band, fan two has a red band) to supply the hydraulically driven fan motor. This tractor lever is locked in full pressure position while seeding. Some models are configured with a single fan while others may be configured with dual fans. Fans are driven by hydraulic motors with speed controlled by the tractor hydraulic flow system. Fan speed is indicated on the monitor panel in the cab. Set fan speed to effectively transport the seed.
Figure 29 NOTE: In the case of a single fan configuration used to double‐shoot product, follow the above procedure and adjust the position of the air damper, Figure 29, to set an effective air flow for each product. NOTE: DO NOT set fan speed above 5000 rev/min. Excessive fan speed will damage the fan drive motor and requires more power from the tractor hydraulic system.

Solution: With the system turned on, go the sensor that is not communicating. There is a LED on each sensor (except the multilevel bin sensor). If it is flashing slowly (1 flash every 2‐3 seconds) that indicates that power and ground are connected but the sensor wire is not.
7.4.7 ERROR MESSAGES Time out alarm, in 20 seconds if ground speed is below 2 MPH. Typical Start Up Alarm, screen when a sensor is not found. Time Out Alarm, in 20 seconds if the drive is not engaged. Rate Not Achieved, The meter cannot turn fast enough to apply the desired rate at the travel speed. Fan Too Slow Alarm, Will come up if drive is engaged and forward speed is present and fans are not turning. This alarm cannot be acknowledged, you must stop and correct the problem.
Meter Alarm, Shows if meter rotation is not sensed with drive engaged and ground speed present. Start Up Alarm, Indicates a connection problem between the motor sensor and the control module. Meter Stopped, Meter is not turning with ground speed present and drive engaged.
8.0 HYDRAULIC DRIVE All aircarts equipped with the Raven Viper Pro™ monitoring system have hydraulically driven meters. These motors have a maximum speed of 113 RPM and a minimum speed of 2 RPM. Speeds in excess of the maximum may result in premature wear or failure of the motors. Reducing the rotational speeds of the motor below 2 RPM may result in erratic metering which may affect the seeding rate. Each hydraulic motor requires a flow rate of 1.0 gallons per minute. The maximum torque output is 26 ft‐lbs.
3. Remove spur gear from agitator shaft, Figure 302. Figure 30 4. Substitute roller, Figure 33. Installing a roller is often easier done with the front cleanout door removed. 5. Replace the hydraulic motor and hydraulic motor mount. Tighten the flange nuts back onto the meter body. Replace hydraulic motor spacer and lynch pin onto roller shaft.
8.1 FILTER AND PRESSURE REDUCING VALVE There is a filter placed in‐line with the hydraulic motors which is located at the front of the aircart near the diverter valve for the auger or conveyor. The filter is equipped with a blockage indicator which displays a red band when a pressure differential greater than 5 bar (72.5 psi) occurs. Note that low oil temperatures may give false blockage indication. To reset the blockage indicator press the plastic cover at the top of the indicator.
8.2 REMOTE CALIBRATION 8.2.1 VIPER PRO™ HYDRAULIC DRIVE CALIBRATION ATTENTION: Exit to the Seed Hawk Viper Pro™ Main Menu on the Viper monitor before powering up the Remote Calibration Console.
