396-001060 SureFire Tower for JD GS2 & GS3-PWM Control Revised 09/03/2015

General Description

A

You have purchased a SureFire fertilizer system for your equipment. This system will be controlled by your John Deere GS2 or GS3 display and John Deere Rate

Introduction

Controller, which you will need to purchase from your John Deere dealer. The GS2

2600 and GS3 2630 function almost identically in regards to rate control. The Rate Controller will adjust the speed of the SureFire electric pumps based on feedback from the flowmeter and vehicle speed. The system is capable of using John Deere Section Control to minimize overlap areas with optional section valves.

Basic Installation Steps

1. Have John Deere Rate Controller mounted and wired by your John Deere Dealer to connect to your GS2 or GS3 display in the cab.

2. Open the packages and familiarize yourself with the components. See the System Overview

Examples on the following pages to see the big picture of how SureFire Fertilizer Systems are installed. Refer to manual sections B & D for component information.

3. Mount the Tower or Accelerator Tank on your equipment. Electric pumps should be located close to the tanks. They will push the product a long distance, but are not as good at pulling product a long distance.

4. Plumb the tank to the Tower inlet. See section E for details.

5. Install the plumbing kit including section valves, flow indicator columns / manifolds, check valves, plumbing to each row unit delivery point. See section B for information on these components.

6. Attach the flowmeter outlet to section valve or manifold inlet. Attach section valve outlets to flow indicator inlets.

7. Attach harnesses as shown in Section D.

8. Setup Controller for SureFire fertilizer system as shown in Section F.

9. Fill system with water, conduct initial operation and tests per Section F.

SureFire Ag Systems

11. Do pre-season service each year as described on page 49.

Electromagnetic flowmeters are superior to traditional turbine flowmeters in two basic ways. First, they have no moving parts. This translates into no wear items or potential for contaminants to jam a spinning turbine.

Second, electromagnetic flowmeters detect the flow by electrically measuring the velocity of the liquid, which makes them independent of viscosity or density of the fluid measured. They are extremely accurate using the standard calibration number. SureFire still recommends you perform a catch test to verify the system is properly installed and configured.

Pressure Sensor

The Tower 110 and 200 come equipped with a 100 psi pressure sensor to work with the

B

John Deere controller. This sensor is a 3 wire type sensor for compatibility with John Deere.

Components

The sensor has a 1/4” MPT fitting.

Liquid

The John Deere Rate Controller is able to accommodate 2 pressure sensors, both of which can be displayed on the GS3 display.

The John Deere display will show the system pressure on the in cab screen. The pressure reading is only

for informational purposes and is NOT used in the flow control process. Flow control uses the flowmeter feedback only.

The pressure sensor is very helpful to optimize system performance and trouble shoot any issues.

The pressure transducer is factory calibrated and will display a very accurate pressure reading on the Deere display. No manual gauge is required.

Pump Priming and Air Bleed Valve

An air bleed valve is included with each pump to aid in system priming. It is shipped in the pump accessories bag and must be installed during system installation.

Why use an air bleed valve:

Most fertilizer systems are equipped with a 4 lb. or

10 lb. check valve on the end of each hose delivering fertilizer to the ground. These valves do not let air escape from the system, unless it is pressurized. 12 volt liquid pumps are not good air compressors. Therefore, the pump can struggle to prime due to air trapped on the outlet side of the pump.

The air bleed valve is a small 1/4” valve that when opened lets air escape from the pump outlet at zero pressure. Open until liquid comes out and then close the valve.

Shipped from factory with plug installed.

How to install the air bleed valve:

Remove the 1/4” plug from the quick connect fitting on the center cross on the Tower (see picture).

SureFire Ag Systems spot on your equipment. Next, cut the tubing and push the 1/4” valve onto the tubing. Finally, run the tubing to a low location where any fertilizer that escapes will run on the ground.

Be sure the air bleed valve tube does not become plugged with dirt or it will not allow the

air to bleed.

1/4” Tubing

1/4” air bleed valve


Product Distribution

To assure proper and even distribution to each row, the product being applied must be metered to each individual row. This metering is done by one of the 3 following methods which create back pressure so an equal amount of liquid is applied to each row.

1. A metering orifice may be placed in the top cap of each floating ball flow indicator. (See photos on page 10—this is not used very often.)

2. A metering orifice may be placed in the check valve cap in the line that leads to each row. (See photo on page 12)

3. A dual metering tube kit with dual check valves may be used. (See pages 16-19)

Floating Ball Flow Indicator & Manifold System

Flow indicators give a clear visual signal that a fertilizer system is working. These indicators use an o-ring and wire clip connection to snap together in any configuration necessary.

SureFire has simple tee brackets and U-bolts that will mount these to a variety of bar sizes.

Two main types of flow indicators are used. On 30” row spacing, the low flow column with 1/4” push to connect outlet is recommended for rates under 10 GPA. For rates over

10 GPA the full flow column with 3/8” hose barb outlet is preferred.

(mostly 1/4” QC)

The low flow column has a smaller internal diameter. This means a heavier ball can be used to monitor a smaller flow.

SureFire uses the low flow columns with 1/4” push to connect outlet fittings. The flow capability of 1/4” tubing and the low flow column are a great pair for rates on 30” rows under 10 GPA.

Externally, the low flow column can only be identified by “Low Flow” molded into one side of the column. All the same fittings work with low flow and full flow columns.

Check Valves

10 lb check valve with 3/8” hose barbs

The recommended check valve for most PumpRight installations is the 10 lb check with 3/8” hose barbs. This works with 3/8” rubber hose which SureFire recommends for most applications over 10

GPA on 30” rows. The recommended minimum system operating pressure for this check is 20 psi, to ensure all checks open fully.

Dual Metering Tube Plumbing Kits with

Dual Check Valve

B

Components

Liquid

SureFire dual metering tube plumbing kits are a great way to plumb a planter to apply starter fertilizer.

They’ll also work on other implements when applying low rates of fertilizer.

These plumbing kits will contain everything you need to distribute fertilizer from the flowmeter outlet down to the ground application device of your choice (not included).

These instructions will show you where all the pieces go. It will provide guidance on how much metering tube to use. There are some optional fittings included in each plumbing kit. These instructions will show you where and why you’d want to use the optional pieces.

The dual check valve assembly is a key piece in the dual metering tube design. In addition to a check valve to stop fertilizer from draining when the system is shut off, each check valve has an on/off valve on top of it. These on / off valves allow the operator to turn on only tube

1, only tube 2, or both tube 1 and 2. This provides for three different application ranges, which is especially helpful when using Black Label

Zn fertilizer (or any other liquid) which has a highly variable viscosity based on temperature changes.

Dual Advantage of Dual Metering Tube

Metering tube provides a larger passage way diameter than a comparable orifice. For a 5 GPA rate on 30” rows, a size

0.046” orifice would be used. For the same rate a 0.110” meter tube that is 8’ long would be used. This 8’ tube with more than twice the diameter creates a fertilizer system resistant to plugging while providing excellent row to row distribution.

By using two metering tubes, the fertilizer system can handle

Black Label ZN (or most other liquid solutions) and provide the proper system pressure as the fertilizer properties change due to temperature, mixtures and other factors.

The dual metering tube allows for three application rate ranges. Black Label ZN fertilizer has a widely variable viscosity. Therefore, based on temperature, tank mixing and fertilizer batch, the best tube to use will change.

SureFire recommends you start with the Green

Use 1/2” or 3/4” hose with hose clamps to connect all check valves.

This is a general diagram showing the dual check valve assembly mounted on a planter toolbar. The check valve and bracket are very flexible in their mounting. The check valve can mount behind, directly over, or in front of the toolbar. The check valve can be put in the bracket facing up & down or sideways (shown). In addition the steel bracket could be rotated 90 degrees and clamp around the bar. The multiple slots in the bracket are used to mount to any tube 7x7 inches or smaller.

Dual Check Valve Assembly Steps

Follow these steps to mount each check valve to the steel bracket.

1. Screw the 3/8” MPT x 3/4” HB tee or elbow into the check valve using blue thread sealer. Orient the hose barb to run the 3/4” hose down the planter toolbar.

2. Insert the check valve into the “C” notch in the end of the bracket, according to how you want the check valve to be mounted on your planter. Orient the wire clips up or to the side for easiest access.

3. Slide the small “C” clamp bracket around the check valve to lock it in place.

4. Install the 1/4” carriage bolt and flange nut to secure the “C” clamp plate around the check valve.

5. Now, mount the check valve on the bar. Hold the check valve and long bracket assembly on the toolbar. Slide the tab on the front of the short bracket into the upper or lower notch on the long bracket.

6. Slide the L bolt into the appropriate slots on the brackets for your tube size. Tighten the 1/4” flange nuts to hold the bracket in place.

Check Valve Mounting Options

The dual check valve mounting bracket is very flexible to fit many different planter configurations. Three options are shown here to illustrate some of the possibilities.

Example 1. Use the long bracket on the top of a bar. The check valve is mounted vertically. The liquid supply hose is ran directly on the front side of the bar. The U-bolt is placed in slots to clamp on a

4x6 inch tube.

Example 2. Use the long bracket on the rear of a bar.

The check valve is mounted over the top of the bar. The supply line would run above and behind the bar.

The short bracket

Example 3. Use the long bracket on the front of a 3x7 bar (vacuum tube on some planters). Mount the check valve hanging forward of the bar. The supply line will run directly over the bar. The excess

When using a 3/8” OD stainless steel tube to apply fertilizer to the ground, there are two options for the delivery tube plumbing. If the tube ID is less than 1/4” (tubing will not fit inside tube) this attachment method must be used. The description following is for Option 1. See bottom right picture for Option 2.

1. Use the 1/4” x 3/8” QC fitting shown. Push the 3/8” end onto the stainless steel tube. (Hint: if the fitting slips off the stainless steel tube, use sandpaper or a file to roughen the end of the tube slightly)

2. Use a short piece of 1/4” black tubing to connect the Y fitting to the reducer fitting on the stainless steel tube.

3. Zip all tubing to the planter and row unit in as many locations as possible.

Option 1: QC Fitting attaches to SS Tube

Option 2: 3/8” Hose attaches to SS Tube

John Deere Rate Controller for GS2 & GS3

D

Wiring & Elec.

SureFire Fertilizer Systems begin at the John Deere Rate Controller, which you will need to purchase from your John Deere dealer. The picture below shows the John Deere Rate Controller. A John

Deere Rate Controller can control one product. Therefore, if you were applying two liquid fertilizers on your planter, you will need three rate controllers, one for seed and two for liquid fertilizer. The John Deere

Rate Controller communicates with the John Deere GS2 or GS3 display in the cab.

The harness coming from the rate controller is a 37 pin Amp connector. SureFire Fertilizer System harnesses begin at this 37 pin connector. The following page shows a system layout to illustrate how the harnessing is connected to all components. Detailed harness drawings follow for information and troubleshooting.

Instructions for setting up the GS2 or GS3 display are in Section F. Detailed screen shots of the display are included showing exactly what settings are required and recommended for SureFire Fertilizer

Systems.

See your John Deere Rate Controller Operator’s Manual for more setup and operating instructions.

(Pulse Width Modulated Electric Pump Driver)

Item Number: 205-18385 (replaces 205-18007 and -18120)

D

Wiring & Elec.

The Electric Pump Driver powers 1 or 2 electric pumps by providing a pulse width modulated signal to control pump speed. It needs to have a power connection and wiring capable of carrying up to 40 amps of current.

It must be connected directly to the tractor battery. SureFire recommends 10 gauge (or heavier) wire if extending harnesses in the field.

PN 205-2201Y1. 40 Amp in-line fuse

Troubleshooting Tip:

If the pumps won’t run, connect the power and pump connector directly together to give pumps full 12 volts directly from battery. This will bypass the EPD module and tell you if the pumps are the problem or if something else is wrong. The pumps will be running at full speed, so don’t leave them connected this way for long.

Use EPD Power Harness Extensions as needed

Floating Ball Flow Indicators

Flow Indicators are extremely flexible and can be mounted in hundreds of different configurations on various types of liquid application equipment. This page is to give you some ideas and let you customize the installation for what works best on your equipment.

16 Row

Split 6 - 4 - 6

This configuration works well on a 16 row front fold planter.

Each flow indicator manifold is shown fed by a cross in a single section installation.

Each manifold could be fed by a section valve if desired.

E

Installation

Overview

From Flowmeter Outlet

A tee will be used in this location with 2 manifolds.

12 Row

Split 3 - 3 - 3 - 3

Shown here is a 12 row with four 3 row sections controlled by four section valves. Note each 6 row T-Bracket can hold two separate 3 row manifolds.

A 4 section 24 row could be similar with four 6 row manifolds on two large T-Brackets.

NOTE: Another option is the flange can face forward so the

T-Bracket could be mounted on the front side of a bar.

12 Row Dual Product

Product 1 Split 4 - 4 - 4 / Product 2 Split 4 - 4 - 4

In this case each manifold would be fed by a section valve. There would be 6 total section valves

(3 sections X 2 products). Most often one set (top) of flow indicators would be Full Flow for high rate fertilizer and 2nd set (bottom) would be Low Flow for starter.

General Plumbing Guidelines

From Flowmeter Outlet

This is usually

1/4” OD tubing or

Minimum 3/4” hose used to feed each manifold.

Length of this hose can vary significantly.

Product 1 on top

3/8” hose.

Maximum

SureFire Ag Systems and lengths do not need to be equal.

This is usually 1/4” OD tubing or 3/8” hose. Typical length is

1-4’ with check valves placed on each row that distance from ground.

Tractor Front Mount Elliptical Cradle Tower Mounting

Bracket

Item Number 511-1009

Mounts a Tower directly to the front of tractor front mount 200 & 300 gallon elliptical tank cradles. This bracket will mount the back of the tower just over 4 1/2” forward of the flat bracket mounting face. When using a tractor mounted tank, SureFire recommends mounting the

Tower near the tank, not back on the implement. Electric pumps work better to push the liquid than to suck the liquid a long distance into the pump inlet.

From fertilizer tank

(3/4” Hose)

Pump Inlet Flow from filter

Do I need recirculation flow?

Recirculation flow allows the pump(s) to run faster than if the total pump flow was applied to the ground. This is helpful when operating at very low flow rates. On a Tower 110 equipped with two 5.3 GPM pumps, you likely will NOT open the recirculation valve if applying over 1.5 GPM to the ground.

How to use the Recirculation Adjust Valve:

Follow these steps to set the agitation adjust valve after your system is primed and tested:

1.On the Deere display go to Tests and choose Nozzle Flow Check. Enter your field operating speed and rate. Turn your master switch on. The system will now operate at your Target Rate and Test Speed.

2.Start with the recirculation adjust valve completely closed and note the slow pump speed (by pump noise).

3.Open the agitate adjust valve slowly and note the increased pump speed and noise. The system is applying the same amount to the ground, the pumps are now running faster due to more recirculation flow.

4.Set the valve to somewhere in the middle based on visual observation of agitation flow needed.

5.On your Deere display, verify the system has locked on to application rate at your agitation valve setting.



Troubleshooting:

 If the system is applying a rate lower than your target, you need to close the agitation adjust valve some.

SureFire Ag Systems flows, one pump may deliver the needed rate and produce a more stable flow.

 If the rate is still fluctuating around your target and you have a two pump system, unplug one pump. At low

What if my product needs agitation?

 Tower Electric Pump systems can provide minimal agitation. On the Tower 110, simply remove the tee located below the recirculation valve. Connect the main hose from product tank to the filter and connect the tank agitation hose to the recirculation valve.

Tower 200 Valve Operation

E

Installation

Overview

System Mode Valve: This valve selects if you will apply to the rows. Valve must be in the

up position for field

operation. Move down to

Agitate Only for tank mixing prior to field operations.

Agitation Adjust Valve:

This valve adjusts how much flow returns to the tank while working in the field.

Tank Selection Valve: This valve selects if product is pulled from the fertilizer tank or rinse tank. For field operation

the valve must be up. Move down to Rinse Tank to flush fertilizer system.

Agitation On/Off Valve: This valve will shut off agitation flow without the need to move the agitation adjust valve. This

valve must be closed when rinsing the system with product still in the fertilizer tank. If not closed, the rinse water will be injected into the fertilizer tank through the agitation line.

How to use the Agitation Adjust Valve:

Agitation or recirculation flow serves two purposes. First, it mixes products that will separate. Second, it allows the pump(s) to run faster than if the total pump flow was applied to the ground. The pump(s) will become difficult to control if they are operated at the slowest speed possible. By circulating product back to tank, the pump(s) will run faster, producing a more stable flow.

Follow these steps to set the agitation adjust valve after your system is primed and tested:

1. On the Deere display go to Tests and choose Nozzle Flow Check. Enter your field operating speed and rate. Turn your master switch on. The system will now operate at your Target Rate and Test Speed.

2. Open the Agitation On/Off valve.

3. Start with the recirculation adjust valve completely closed and note the slow pump speed (by pump noise).

4. Open the agitate adjust valve slowly and note the increased pump speed and noise. The system is applying the same amount to the ground, the pumps are now running faster due to more recirculation flow.

5. Set the valve to somewhere in the middle based on visual observation of agitation flow needed.

6. On your Deere display, verify the system has locked on to application rate at your agitation valve setting.

SureFire Ag Systems

If the system is applying a rate lower than your target, you need to close the agitation adjust valve some.

If the system is applying a rate higher than you want and will not lock on rate, you need to open the agitation adjust valve some.

If the rate is still fluctuating around your target and you have a two pump system, unplug one pump. At

low flows, one pump may deliver the needed rate and produce a more stable flow.

PWM Setup

From System Setup screen, push “PWM Setup” to open this screen.

F

Setup &

Operation

1. Control Valve Calibration: 9911

The John Deere Rate Controller Control Valve Calibration can be changed to optimize performance on your specific equipment. The 4 digit number is formatted XXYZ.

Increase XX to make the system respond quicker. If set too high, the actual rate will oscillate around the target. Y is the output deadband and Z is the control deadband. Generally leave these two digits low. Read your JD Rate Controller

Operators Manual for more information. For example, to slow your response speed, move the number from 9911 to

8011, changing the valve response from 99 to 80.

SureFire has found the fastest setting has the best performance with electric pump systems.

20

2. Coil Frequency: 100

3. High Limit: 255 (maximum value allowed)

4. Low Limit: 20 ( If you are applying a very low rate and pump

will not slow down enough, you may have to set this at 15 or else open the Recirculation valve slightly.)

The “Calibrate PWM Limits” button is not necessary after you enter the numbers above. SureFire recommends you NOT use that procedure, and use the settings shown here for optimum performance.

5. Push the lower right button to return to the System Setup screen.

Calibrate Pressure Sensor

From System Setup screen, push “Calibrate Pressure Sensor” to open this screen.

1. Select Voltage-

based Calibration

2. On the screen that opens up, enter

50.0 mv/psi.

Tip: If the system has been running, there may be pressure in the system due to the check valves. In that case, simply unplug the sensor while this setup is being done so it will calibrate the zero point correctly.

3. Push the lower right button to return to the

System Setup screen.

Setup - Alarms

Customize your alarms and settings on this page.

F

Setup &

Operation

1. Low Tank Level can be used by the customer if they desire, but is not required.

2. High and Low Alarm: 20% is the John Deere default and SureFire recommended setting. SureFire recommends these alarms be enabled (checkmark in the box).

3. Minimum Pressure: 10 psi is a safe minimum pressure to ensure all check valves (4 psi setting) are fully opening and equal flow will go to every row. SureFire recommends turning this alarm off as each time the system turns on & off it will activate, being a nuisance.

4. Maximum Pressure: 40 psi is the recommended setting.

Electric pumps will draw more current and reduce output flow as pressure increases. If

pressure is routinely over 30 psi, consider changing to a larger orifice for optimum

performance. Turn this alarm on so you are warned when system pressure increases for some reason (cold morning operation may trigger this alarm).

Setup - Rates

Enter your desired application rate(s) here.

1. Enter up to 3 rates.

2. SureFire recommends checking the Rate

Smoothing box and entering 10%.

3. SureFire recommends leaving minimum flow

rate at 0.0. If greater than zero, this is the

SureFire Ag Systems system will NEVER go lower than. Optionally, it could be set to the minimum flow limit of your flowmeter.


Initial Operation Instructions - Step 1

SureFire highly recommends you perform these exact steps with water to verify system is correctly installed and ready for field use.

F

Setup &

Operation

1. Go to the Section Test (Diagnostics, Tests, Section Test). Section Test essentially functions like a MANUAL mode where you have direct control of pump and valves.

2. Turn the Master switch on.

3. Test section valves by checking and unchecking boxes. Check boxes to open all valves.

4. Push the “+” button and hold it. Electric pump(s) should begin running. (It takes lots of individual taps of this button to cause a visible effect).

5. Is water being pumped? If system is not primed, open the priming air bleed valve. This will allow air to be expelled and the pump to prime.

6. With pump running and water flowing, push “1,2,3” button. Look at flow in GPM. Is there a reading there? If not, is the system primed with water flowing to every row? If water is flowing, but no reading, check flowmeter calibration and wiring harness connections.

7. Push wrench button, now push the

“-” button. Go back to the “1,2,3” screen. Did the flow in GPM decrease?

8. Make sure the GS2/GS3 flow readout in GPM can be increased and decreased with the plus & minus buttons.

Go to Step 2 on the next page when you can increase and decrease the GPM reading using the + and - buttons.

Helpful Tip

The Section Test is the first and most basic test to make sure that the system is set up and hooked up correctly. This test verifies that you pump.

SureFire Ag Systems

If there is a problem with the operation of the system, start with the Section Test.



1. Go to the Nozzle Flow Check (Diagnostics, Tests, Nozzle Flow Check ). This test will operate the system as if it were running in the field at a speed and application rate you enter.

2. Test Speed: Enter your typical field operating speed.

3. Rate: Enter your typical application rate.

4. Turn the Master switch on.

5. Pump will turn on and begin applying the entered rate.

F

Setup &

Operation

6. Observe the system. Are the flow and pressure on the screen stable and reasonable? Is the flow reasonable and equal from each application point?

7. Repeat this test at

minimum and maximum values for both Test Speed and

Rate. Remember heavier fertilizers, such as 10-34-0, will have higher pressures at a given flow than water.

8. You can use this procedure with fertilizer (instead of water) to verify your minimum pressure is at least 10 psi (to ensure all check valves open). Also check the maximum speed and rate to make sure pressure is under 40 psi (to limit electrical current to pumps). When testing with water, the pressure will be much

less than it will be when using fertilizer.)

Another test available to verify system performance is the

Configuration Test.

This test checks the operation of each section valve. It also checks the ability of the controller to control the flow at various flow rates.

SureFire Ag Systems



This test is required before the

John Deere Rate Controller will work properly and quit warning the operator to calibrate the flowmeter.

It also serves as a check that the entire system is setup correctly.

1. Go to Calibrate Flowmeter -

Catch (Diagnostics, Tests,

Calibrate Flowmeter -

Catch). The Calibrate

Flowmeter screen will pop up.

2. Number of Nozzles that will spray: Enter total rows on equipment.

3. Test Speed: Enter typical operating speed.

4. Rate: Enter typical application rate.

5. Volume to dispense: Enter volume that you are capable of catching and measuring from a single nozzle (in ounces).

6. Push continue button in lower right corner. Turn master switch on and begin test.

7. The screen to the right will pop up after test is complete. Enter the sample size collected from 1 row. You need enter only 1 sample measurement.

The GS2/GS3 then calculates the new flowmeter calibration value based on the average sample size.

F

Setup &

Operation

With SureFire Electromagnetic flowmeters, most times the sample volume is correct. In that case, just enter the same sample size you did in #5 above to leave the calibration value unchanged. If the sample volume differs from what is expected, recheck the calibration settings. Do not change the calibration value if there is a small difference in the sample volume.

SureFire recommends that you do not change the Flowmeter

Trouble-

EPD flashing 4 times

shooting

1. Find the EPD (electric pump driver) shown above. Should have a steady blinking light in the middle when pumps should be off. If Status LED is flashing 4 times, then pausing, EPD has tripped due to low voltage condition. Unplug the Power Supply to the EPD to reset. If condition persists, change to larger orifices to reduce pressure, slow down, or lower application rate. Check Power Supply cables to

EPD to insure solid connections and good electrical path.

No Lights on EPD

1. There should be a steady blinking light in the middle of the EPD. If no light is ON, check the 40-amp fuse in the EPD harness near the battery. Use a voltmeter to verify that there is 12-13 volts at the Power Supply connector that plugs into the EPD.

Will pumps run?

1. Connect the two large connectors that are plugged into the bottom of the EPD to each other (bypass the module and supply 12 volts directly to pumps).

2. Do the pumps run? If not, check the 40 amp fuse in the EPD harness near the tractor battery. Inspect harnesses and connections. If 2 pump system, plug pumps in by themselves to check both.

Electric pumps only run with 12 volts direct from battery

1. Connect pumps and power harness back to EPD.

2. Go to Diagnostics, Section Test to investigate this issue.

3. In Section Test, hold down “+” button for a few seconds. A single tap of this button produces a very small change in signal to the valve, so you must hold it.

4. Remove PWM valve connector and check voltage. You will need 1-12 volts to turn pumps on.

5. If 1-12 volts is not present, check harnesses and review control valve type setup.

6. Go back to the 37 pin connector at the John Deere Rate Controller. Check voltage between pins 15 & 16, should be between 6-12 volts while in section test after holding “+” button.

7. If you cannot get voltage at pins 15 & 16, contact your John Deere dealer for further assistance.

Section Valve(s) will not move

1. If in the field, be sure you are not in an area that the controller thinks has been covered already or that is out of bounds.

2. Go to Diagnostics, Section Test to investigate this issue.

3. In Section Test, check and uncheck the boxes. With the box checked the valve should turn on. The valve should be off with the box not checked.

4. Check the harness connection to that valve. It is a 3 Pin Weather Pack con-

B Ground nector. See Section D for wiring diagrams

C + 12 V Signal

5. Check voltage pin A to Pin B. Must be 12 volts, if not, go back to 37 pin and check voltage (pins 36 & 37 are +12V, pins 1 & 2 are ground).

SureFire Ag Systems or open, this should be zero volts when valve is off or closed.

7. If signal voltage is not present to open valve, use diagrams to check at the 16 pin , then the 37 pin for voltage on the proper pin for that section.

8. Switch connection to valve that is not working with a connection to a valve that is working.

9. If constant voltage (Pins A&B) and switched voltage (Pins C&B) are present, inspect, repair or replace the valve.


Application Rate & Flow Troubleshooting

G

Application Rate Fluctuates

First, you need to determine if the fluctuation is caused by the controller sending fluctuating signals to the valve.

1. Inspect & clean pump inlet strainer. Strange flow rate fluctuations are very often due to an obstruction to the pump inlet. Inspect plumbing from tank to pump.

Troubleshooting

OR

1. Go to Section Test as shown in Initial Operation, Section F.

2. Turn the system on and watch the flow in GPM on the 1,2,3 screen.

3. Is the flow steady within a very small range? For example a fluctuation from 2.3 to 2.5 GPM would be considered normal. A fluctuation from 2-3 GPM is a problem. If only a small normal fluctuation is seen, skip steps 4-8 and proceed to “Application Rate Fluctuates in Field …….. “ below.

4. If there is a large fluctuation, observe the system flow. Is the discharge a steady stream? Are the flow indicator balls floating steady?

5. If visually the flow is steady, but the display reports a fluctuation in GPM, inspect the flowmeter. See section B for flowmeter information.

6. If visually the flow is unsteady, the flowmeter is working correctly reporting a flow problem. Is the pump turning steady or surging?

7. Look for any type of obstruction in the pump inlet. Clean the strainer. If continually plugging the strainer, investigate fertilizer quality and necessary strainer size.

Application Rate fluctuates in field, but flow in Section Test mode is stable.

This problem indicates the valve calibration needs changed. The system is surging because the Rate

Controller is moving the pump driver or hydraulic valve too much.

1. Go to Setup - System - PWM Setup.

2. Change the Valve Calibration by reducing the valve speed (first two digits). For example reduce the number for 9911 to 8511, which changes valve speed from 99 to 85.

Application Rate is slow to get to the Target Rate

1. You may need to increase the Valve Calibration. Go to Setup - System - PWM Setup.

2. Change the Valve Calibration by increasing the valve speed (first two digits). For example, increase the number from 8511 to 9911, which changes valve speed from 85 to 99. (SureFire recommends 9911 for

Tower Electric Pump systems, which is the fastest Valve Calibration possible)

3.

If system is too slow to get to the Target Rate when starting, go to Setup—System - PWM Setup. Raise the Low Limit. (If Low Limit is 0, set at 25. This will start the pump at a faster speed when it initially turns on

. (This number sets the low limit of your pump, so if it is set too high your pump may not be able to slow down enough at low speed/low rate settings or with some sections turned off.)

4. Optional Method 1 to get to Target Rate faster: (Caution: You can only use this method if you have Electric Section

Valves.) Go to Setup - System. Set Control Valve Type to PWM. This leaves the pump running at the last speed when product application is stopped. Under PWM Settings check the Pump Enable Checkbox. With the section valves closed and the pump running, this can build up too much pressure in the system at times. To reduce this pressure, open the Continuous Recirculation Flow Throttling Valve on the Tower slightly (see page 30-31). Since this

SureFire Ag Systems

run at a higher speed all the time.

5. Optional Method 2 to get to Target Rate faster: Use the John Deere Rate Controller Flow Return feature. This will

involve adding an additional electric valve and plumbing to return flow to the tank when product application is stopped. On the Setup - System screen, check the Flow Return box. In Setup - System, the Control Valve Type is set to PWM. Under PWM Settings check the Pump Enable Checkbox. With the Control Valve Type set to PWM, the pump continues to run at the last speed it was running when product application was stopped. Flow at this time

is returned to the tank. When product application is resumed, flow is diverted from the tank back to the rows.


No Flow shown on GS2/GS3 but liquid is being pumped

Flowmeter Tap Test

1. Unplug flowmeter. With voltmeter, check for 12 volts between pins B & C of flowmeter connector (on main harness PN 215223Y2). If 12 volts not present, inspect wiring harness and troubleshoot all connections per schematic (see Section D).

G

Troubleshooting

2. If 12 volts is present, then conduct a tap test. Go to setup and change the flow cal to 10. Have a second person watch GPM on the 1,2,3 screen while other person taps (use a short piece of wire or a paper clip) between pins A & C of flowmeter connector (on 215223Y2 harness). (If alone, note or reset a volume counter to 0 and check for increased volume after tapping.) A flow value should show up indicating the wiring is not damaged. Reset flow cal number after testing.

3. If GS2/GS3 responded to the tap test, your wiring to that point is good. If still not fixed, inspect adapter harness and test continuity per schematic (see Section D).

4. Replace flowmeter.

Troubleshooting Tip

1. Useful information is available at Diagnostics—

Readings. The screenshot at the right shows which

Readings are available.

2. Below are examples of some of the screens available:

Check the operation of the flowmeter here.

The PWM Duty Cycle gives an indication of how fast the pumps are running. The range is from 0 to 255.

Sensors/Status

Check the operation of the pressure sensor here. The top number (V) will be between 0 and 5.0.

The Calibration Points should indicate that 0.0 psi is 0.00 volts.

The Slope should be 50.0 mv/psi.


Fertilizer System Flow Verification

I can’t get up to my desired rate. How much flow is required?

Can I achieve a new application rate with my current system?

How much oil does my PumpRight need?

G

Troubleshooting

Follow the steps below:

1. Use the Fertilizer System Flow Charts on the next two pages to find your required flow. First, locate the chart for your implement size. Next, find your operating speed on the left side and your application rate on the top. Record the flow in gallons per minute for your maximum speed and rate and your minimum speed and rate.

A. Maximum Flow __________________ GPM (Max Rate & Max Speed)

B. Minimum Flow ___________________ GPM (Min Rate & Min Speed)

2. Locate your pump model on the chart on this page. Will the pump model provide the maximum flow you need from above?

3. Find your flowmeter model in the chart on this page. Will the flowmeter work at both the maximum and minimum flow your recorded in step 1? If not, a different flowmeter is required.

4. If using section valves you must complete this step.

A. Minimum Flow (from above) ÷ Total Rows = ______________ GPM / Row

B. GPM / Row (from line above) x Rows per section = _______GPM / Section

Will your flowmeter measure the minimum GPM / section?

Recommended Care and Maintenance

Winterization

Maintenance

SureFire recommends flushing your fertilizer pump and complete system with adequate amounts of water first. Next, use RV antifreeze to winterize your system by pumping an

& Parts adequate amount through all components. At the beginning of the next season, begin with water to verify the system is in working order with no leaks.

Inspect Electric Pumps

The electric pump and motor is a completely sealed component. Over time the electric motor will lose efficiency. The entire pump and motor will need replaced when it won’t efficiently produce the flow required.

Each individual pump should be able to produce more than 4 gpm of water flow with an open outlet (zero pressure). If pump falls short of this specification, replace to ensure a trouble-free fertilizing operation.

You can test the operation of each pump individually by unplugging one pump and running one pump at a time. Compare the output of each pump to each other and to the standard above.

Pre-season Service

(A little time spent here may prevent some downtime when you want to be rolling.)

1. Visually check entire system (hoses, fittings, harnesses, etc.) for any signs of wear or trouble.

2. On the display, recheck all setup screens (see Section F) to verify correct setup.

3. Fill system with water and run in Manual mode (Section Test) to verify components and system are in working order. (May need to open air bleed valve to prime pump the first time.)

4. Unplug one pump at a time to verify that each pump is operating as it should.

5. Tighten all clamps. Loose clamps may be evident by leaks on the output side of the system. Loose clamps from the tank to the pump are not always apparent, but can be sources of air getting into the system which can create issues.

6. Remove the black cap from the top of each check valve. Check the diaphragm to be sure it is intact and not gummed up with residue. Look under the diaphragm for debris. Compress the spring in the cap to be sure it moves freely. Carefully replace diaphragm and tighten cap.

7. Remove and clean the strainer. Be sure strainer is tightened securely so it will not suck air.

8. Be sure all rows are flowing and that all metering tubes/orifices are open. (Note: It will take a higher flow rate with water to create enough pressure to open all the check valves.)

9. Run the Nozzle Flow Check to verify that system will lock on to a Target Rate.

1. The EPD module should have a slow steady flashing light in the center LED when it is plugged into battery power.

2. If the center LED is flashing fast 4 times, followed by a short pause, and then 4 quick flashes, unplug the power from the battery to reset. If problem persists, this is a low voltage problem. Check cables and connections back to battery.

3. When the pumps should be running, the center LED will be steady red. The corner LED should be red to indicate it is receiving PWM signal.

4. Plug pumps directly into power from battery to verify current is there and pumps are working.

5. Run the Section Test to verify that section valves will open and that pumps will run. When + button is held down on

Section Test, the PWM voltage to EPD should go up to 12 or 13 volts.

Section Test can be used for manual operation of the system. It can be used to prime the pump on startup or to rinse the system. It is good for troubleshooting.

Use Nozzle Flow Check to see if system will lock on to a rate at a test speed. Pressure with water will be a lot lower than it will be with a heavier, thicker product.

Diagnostics—Readings—Delivery System will show details on flowmeter operation and pump speed

(PWM Duty Cycle). This can be useful information for troubleshooting.

Flowmeter Tap Test

1. Unplug flowmeter. With voltmeter, check for 12 volts between pins B & C of flowmeter connector (on main harness

PN 215223Y2). If no voltage, check at each connection back to Rate Controller.

2. If 12 volts is present, then conduct a tap test. Go to setup and change the flow cal to 10. Have a second person watch GPM on the 1,2,3 screen while other person taps (use a short piece of wire or a paper clip) between pins A &

C of flowmeter connector (on 215223Y2 harness). (If alone, note volume on volume counter.)

3. If GS2/GS3 responded to the tap test, your wiring to that point is good. If still not fixed, inspect adapter harness and test continuity per schematic (see Section D).

4. Replace flowmeter.

SureFire Ag Systems

1. If one valve is not working, switch connections from that valve with a valve that is working to see if the problem is with the valve or with getting power/signal to the valve.

2. All valves should have constant 12V power between pins A & B. When valve is commanded to turn on, there should be 12V between pins B & C. Start checking at the connection closest to the valve and work back to the Rate

Controller. (See wiring pinouts in main manual.)

3. If using Auto Section Control, be sure the controller doesn’t think you are in an area already covered. Use the

Section Test to open and close valves.
