Installation: Hydraulic Down Force FAQ Where do I plug in an implement switch? Generation 1 modules will broadcast the implement switch status over the CAN bus. additional implement switch is needed. What if I don t have any other generation 1 modules? You will use the Ag Leader CAN implement switch module P/N 4002911 and cable P/N 4002658 in conjunction with the standard implement switch. What if my cables don t reach the rows for which I have installed gauge wheel sensors? It may be acceptable to choose rows the cables will reach, as long as channel 2 sensors are on the center 6 rows, and channel 1 sensors are outside that. What if I don t have any free SCV connections for the down force valve? Teeing into existing lines is acceptable. Do not tee into the vacuum fan line if adjusting fan RPM on the tractor with a knob or dial. Teeing into the line before a flow limiter on the planter would be acceptable. Teeing into the hydraulic drive supply line would be the best option. Do not tee into Rawson Drive supply line. What if my hydraulic oil gets too hot? Ag Leader sells a Load Sense kit (P/N 4101225) to help manage oil temperatures. te: This system will not help if using SCV to control hydraulic drives. In this case, an auxiliary oil cooler may need to be installed. What if my hydraulic actuator does not extend far enough to reach the lower bracket with row unit at bottom travel? Purchase one spacer kit (P/N 4101201) per row. This will install at the bottom of the ram. (Commonly used on John Deere long parallel arms) My Kinze planter has rows that are offset 4 back, causing the upper actuator bracket to not line up with the lower actuator bracket. Purchase one spacer kit (P/N 4101204) per row. This will move the upper bracket 4 rearward. How does the system know the difference between the row modules on channel 1 and those on channel 2? The Channel 1 row modules will connect to the cable labeled Type 1 while channel 2 row modules will connect to Type 2 cables. 5
Installation: Hydraulic Down Force FAQ Am I missing something to plug into the 3 pin connector on the master hydraulic down force module? This connector is not used. Why is the gauge wheel load bar graph constantly spiking and then going to 0? This can happen if the Channel 1 pressure lines are routed to channel 2 sensors. Ensure channel 1 components (Down force pressure, and gauge wheel load sensor wiring) are on the wings, and channel 2 components are on the center 6 rows. Ensure channel hoses are going to correct channel of down force valve. Ensure PWM/pressure sensor cables are going to correct channel of Down Force Module and Down Force Valve. What are the red knobs on the down force valve? This allows for manual adjustment of down force in the event of electronics failure. Push and twist the knob to move between automatic adjustment (inner position) and manual adjustment (outer position). Why does the system need 3 hydraulic lines (Pressure, Return and Tank) Under normal operation, pressure in the down force system is increased through the Pressure line and relieved through the Return line. When the planter runs over a terrace or a water way, the access pressure is released through the Tank line. All three lines MUST be connected. 6
Hydraulic Down Force Alarm Explanation and Resolution Down Force Inadequate Problem: System is at maximum hydraulic pressure, but does not achieve an acceptable gauge wheel load. Often times this alarm occurs when down force actuators are lifting the planter tool bar. Resolution: Add weight to planter. If planter tool bar is not lifting, increase maximum down force setting in configuration setup. Hydraulic Pressure too low Problem: Hydraulic pressure is at 0 and the system is demanding more pressure. Resolution: Check hydraulic hoses for proper connections. Ensure SCV remote is set for continuous flow. Zero each channel s pressure sensor only when mechanical gauge reads 0 psi. Low Gauge Wheel Load Problem: Down force system is not achieving an acceptable gauge wheel load. Resolution: Increase aggressiveness for problematic channel under settings button from run screen. This alarm may be followed by Down Force Inadequate, in which case consult that alarm resolution section. Pressure Sensor Failure Problem: Pressure sensor is outside voltage range. Resolution: swap cables with other channel (if applicable), re-zero pressure sensors. If problem persists on same channel, replace pressure sensor. If problem is now on other channel, inspect/ replace cable. Row Module Communication Lost Problem: Row module communication lost. Resolution: Inspect cabling of row module. Replace row module. Row Module Failure Problem: Row module is not sensing inputs. Row module is power cycling at intervals of less than 2 seconds Resolution: Swap module with different row. If problem follows, replace module. If problem exists on same row, inspect or replace load sensor. # Row Modules does match the display configuration Problem: Configuration was set to a number of sensors that was not detected by the system. Resolution: Create a configuration that matches the number of sensors used. Check that all row modules are communicating. Flashing green LED on the row module indicates proper communication. 7

Down Force Module Communicating? Go to Step 2: Cables and Power Is arrow icon green when planter is lowered? Go to Step 3: Implement Switch Connections Operating Configuration set to control? Set Operating configuration to Control instead of Monitor Only Is arrow icon yellow when planter is raised? Go to Step 3: Implement Switch Connections Restart field operation, select Down Force on Product Selection screen accept Down Force Warning Go to Step 1B: Hydraulic Down Force 8
Troubleshooting Step 1B: Hydraulic Down Force Continued from Step 1A: Hydraulic Down Force Engage down force hydraulics. In Manual Control click the increase arrow several times. Does pressure increase? Go to Step 4: Hydraulics Put planter in down position with load on gauge wheels. Place in manual control at maximum pressure. Enter down force module diagnostics. Do all row sensors register a load reading? With planter still in down position with load on gauge wheels and in manual control at maximum pressure Can the gauge wheels on the monitored rows be turned by hand? Go to Step 2: Cables and Power Move to softer ground or pull forward. The opening discs are not digging into the ground. Decrease pressure in manual control. Does the pressure displayed go down. Go to Step 4: Hydraulics Return system to desired control mode. Manual/ Automatic Troubleshooting Complete. System should be in field-ready state. 9

Power on Display Are row module lights green? Go to Step 5: Indicator Lights Is CAN A connected? Connect CAN A Does cabling match the Figure 1: Cable Diagram? Correct cabling errors to match Figure 1: Cable Diagram. Check power control relay. Troubleshooting Complete. System should be in field-ready state. 10
Troubleshooting Step 3: Implement Switch Connections NOTE: A minimum of 1 implement switch (2 is recommended) must be installed on planter for the down force system to work properly. If an implement switch is already installed and connected to an existing SeedCommand module, no action is required. If no implement switch is installed, action must be taken to install at least 1 implement switch and implement switch module on local down force CAN Bus. When using the hydraulic down force module with existing Seed Command modules, the implement switch must be connected to the module highest in the hierarchy below: Hydraulic Seed Rate Control Module Clutch Control Module Seed Tube Monitor Module Implement switches connected to any non Seed Command related module will not indicate planter up/down status for Hydraulic Down Force control. (App Rate Module and Liquid Control Module included) If none of the above 3 seed command modules are used then the Hydraulic Down Force module must have a CAN implement switch installed. Part numbers required for CAN implement switch installation: Part Number Description 4002911 Module CAN implement switch 4002658 Cable CAN implement switch 4001507 Implement Switch Implement Switch Kits (contain Implement Switch 4001507) 4100830 Kinze 4100831 John Deere 4100832 White 4100833 Case 11
Troubleshooting Step 4: Hydraulics Start Is Tractor running with hydraulics engaged? Start Tractor and engage hydraulics At the down force control valve, move the red circular manual override knobs to the other position (electronic control override). Is a pressure displayed on the valve s gauge? Move red circular override knobs to the inner position (automatic control). Adjust manual override pressure using allen head adjustment just above the electronic PWM valve. Is pressure still at 0? From the display, Can pressure be released from the system using the down arrow in manual control? From the display, Can pressure be increased in the system using the up arrow in manual control? Ensure Pressure, Return and Tank lines are completely connected. Ensure SCV remote is engaged in the correct direction. Ensure system is set for continuous flow (motor mode). Troubleshooting Complete. System should be in field-ready state. 12
