Safety Information
Configuring vehicles with solenoid boom valves for use with
the EZ-Boom 2010 System
For vehicles equipped with three-wire motorized boom valves, the EZ-Boom® 2010
system controller is rated to drive all ten (10) boom sections.
For vehicles with solenoid boom valves, you may need to modify the vehicle, or the
vehicle configuration, to ensure that the total current draw does not exceed 16 Amps.
C
CAUTION – Before using solenoid boom valves, calculate the maximum total current
draw. Do not allow the total to exceed 16 Amps. A higher current draw can cause the
EZ-Boom controller to overheat and malfunction. To keep below the 16 Amp limit, modify
your vehicle setup or configuration.
Calculating the maximum total current draw
1.Find the maximum current draw for one of the solenoid boom valves. If there is
no rating in the manufacturer’s documentation, contact the vendor.
2.Multiply the maximum current draw for one valve by the total number of
solenoid boom valves on the vehicle. For example, if one valve has a maximum
current draw of 3 Amps:
This many boom
valves...
55 x 3 Amp = 15 Amp
99 x 3 Amp = 27 Amp
Would result in a total maximum current
draw of...
Reducing the maximum total current draw
If the total current draw is greater than 16 Amps, do one of the following:
•Use fewer boom valves on the vehicle.
•Add external relays to each of the solenoid valves to reduce the current draw
from the EZ-Boom system.
•Replace solenoid valves with three-wire motorized boom valves.

CAN communication issue when using cable P/N 62063
Cause
When you use cable P/N 62063 to connect an EZ-Boom system to an EZ-Guide 500
lightbar with an Autopilot
™
system, there is no CAN communication with the EZBoom system. This is because the CAN HI and CAN LO on cable P/N 62603 have been
swapped or there is not a CAN terminator connected to the EZ-Boom cable.
To identify whether there is CAN communication, check the color of the LED on the
EZ-Boom controller. If the LED lights up orange, there is no CAN communication: If
the LED lights up green, CAN communication has been established.
Solution
Replace cable P/N 62063 with the new cable configuration shown below.

B
B
STEP 1: Clear the error message (page 13)
STEP 2: Check the following setup parameters
a.Do a catch test to confirm that the flowmeter calibration number is
correct.
b.Check that the flow control valve setup is correct.
Tip – If your sprayer has a bypass servo, check that there is no crossover cable
connected to the flow control valve. On Raven systems, this cable is required
to allow the Raven flow controller to correctly adjust the valve. On an
EZ-Boom system, this cable is not required. If a crossover cable is not fitted but
the EZ-Boom system cannot properly control a bypass flow control valve, try
changing the control valve setup to Inline Servo.
c.Check that the target rate is within the operating parameters of the spray
nozzles at your spraying speed.
Tip – Refer to your spray nozzle selection chart for information relating to
flow and speed.
If necessary, do one of the following:
–change the spray nozzles
–adjust your target rate and/or speed to match the target rate to the
sprayer nozzles

Operating the Rate Increment/Decrement switch
Description
Setting the amount by which the current application rate (Rate 1 or Rate 2) increases
and decreases each time you press the Rate Adjustment (increase/decrease) switch.
Summary
If you use the pre-selected target rates (Rate 1 or Rate 2), toggle the switch every time
that you want to increase or decrease the rate. When the system is in manual mode,
you can hold the switch in the upward position-the application will continue to
increase automatically. Release the switch when you reach the required rate.
Solution
The Increment/Decrement switch depends on the setting of the Rate switch: Rate 1,
Rate 2, or Manual mode.
Note – The way that the switch works depends on the display you are using.
EZ-Guide Plus lightbar: Rate 1 or Rate 2
Set the Step value in the Application Setup screen.
•To increase the flow by that step value, press the
Increment/Decrement switch up.
•To decrease the flow by that step value, press the

Spray booms do not turn on in a corner
Cause
The sprayer has no ground speed.
Solution
Use the manual-rate-from-stationary mode to spray the corners of fields. This ensures
maximum spray coverage of your field, while minimizing repeat coverage.
1.Drive around the corner while spraying. An area of land is missed.
2.Once you pass the corner and straighten up, stop the vehicle.
EZ-Boom 2010 System Error Messages 1
3.Use the master switch to turn off the EZ-Boom controller.
4.Reverse the vehicle until the spray boom is at the field boundary ( for example,
the fence).
5.Adjust the EZ-Boom controller switches:
a.Set the rate switch to manual mode (M).
b.Turn on the master switch.
Because the vehicle is starting from a stationary position, automated boom
switching is disabled.
Note – Once the boom sections are open, you may need to adjust the flow rate with the rate
adjustment Inc/Dec switch.

6.Begin driving. As soon as the vehicle begins moving, set the rate switch back to
one of the automated spray modes (Rate 1 or Rate 2). This re-enables automated
boom switching. Any boom sections that are re-covering an area that was
previously sprayed will turn off.
7.Continue driving the field as before.

EZ-Boom 2010 System Error Messages 1
The system shuts off when GPS signal is lost
Cause
The system no longer has a vehicle speed input, which the EZ-Boom controller needs
to calculate the GPS position and the spray rate.
Solution
To continue spraying if the GPS signal is lost, switch to manual rate control mode (the
M position), which does not require vehicle speed input. However, the EZ-Boom
controller cannot then calculate an automatic spray rate or adjust the spray rate if the
vehicle speed increases or decreases.
For more information, see System behavior following loss of GPS below.
Note – When in manual mode, use the vehicle speedometer and system pressure gauges to
maintain the correct spray volume.
Rate control and the loss of GPS
To determine a spray rate, you need the following information:
•Sprayer speed (mph)
•Sprayer boom width (inches)
•Flow of spray (Gallons per minute)
Boom control and the loss of GPS
Position information is lost when GPS is lost. Without position information, the
EZ-Boom 2010 system cannot determine the location of the spray boom and so cannot
detect previously-sprayed areas in order to control individual boom sections.
If the system is in the Auto Rate 1 or Auto Rate 2 mode, the loss of GPS turns off all the
boom sections. Switch the rate control to manual mode to turn on the boom sections
and continue to spray.
While the EZ-Boom 2010 system is without a valid GPS position, mapping or coverage
logging is disabled.

Not reading any Applied Rate "With supported flow meter"
Cause
No signal from the flow meter.
Solution
1.Check the flow meter power, signal, and ground wiring:
–Depending on the flow meter, the power wire may have 5 V or 12 V.
–The signal wire should have 5 V.
–The ground wire should show good continuity to ground “under 1 ohm".
2.Check for good continuity on the signal wire from the flow meter back to pin 13
on the harness going to the 16-pin connector on the EZ-Boom controller.
3.If the wires are satisfactory, check for a Hz reading on the EZ-Boom pin 13. You
will need to back-probe the wire to do this test.
–If there is a Hz reading, reinstall the EZ-Boom and display firmware. If that
does not resolve the issue, try a different EZ-Boom controller.
–If there is no Hz reading, try a different flow meter.

Incorrect tank volume message
Cause
Amount that is applied does not match tank volume.
Possible failure modes
•The system reports that there are X number of gallons left, but the tank is empty.
•The system reports that the tank is empty but there are still X number of gallons
left.
Solution
1.Perform a catch test to make sure that the system is outputting the correct
amount for the sprayer tips.
2.If the system is incorrect by a small amount, increase the Cal number slightly to
output more or decrease the Cal number slightly to output less.
Note – The tank volume markings may not be exact; change the Cal number by only a
small amount because it affects how much is being sprayed.

Pressure stays at Set limit on Pressure sensor Cal.
Cause
No change in voltage from the pressure sensor.
Solution
Do one or more of the following:
•Make sure that the pressure changes at the pressure sensor.
•Make sure that the correct sensor (Aux or Main) is calibrated.
•Make sure the slope value is set correctly: 27 mV/PSI for Trimble implements.
•Check for power, ground, and signal voltage at the pressure sensor. Power goes
into the pressure sensor and then the signal voltage out should change when PSI
changes. Back-probe the signal wire and then vary the pressure to make sure
that the signal voltage changes.
•If the signal voltage does not vary with pressure change, replace the pressure
sensor.
•If the signal voltage does vary with pressure change, check continuity from the
signal wire out at the pressure sensor to the 14-pin connector on the EZ-Boom
controller. Main pressure sensor is pin 10; Aux pressure sensor is pin 6.
•If continuity is satisfactory, reinstall the EZ-Boom and display firmware. If that
does not resolve the issue, try a different EZ-Boom controller.

Boom section 1 on an SPX sprayer does not turn on
Cause
There may be a diode molded in the connector on the sprayer.
Solution
Check continuity on pin 6 of the 16-pin connector going into to the back of the
EZ-Boom controller to the boom section 1 signal wire.
If there is a diode in the system, you see continuity with the leads one way and when
you reverse them, you see an open.
In this case, use a Y-harness to jump pin 6 on the Y-harness to pin 6 on the sprayer
harness.
If you see an open with the leads both ways, look for broken wiring from the EZ-Boom
controller out to the number 1 boom valve.

Rate fluctuates around the Target Rate.
Cause
The control valve is either responding too quickly and overshooting the target rate, or
moving too slowly and drifting away from the target rate.
Possible failure modes
Incorrect settings for Response 1, Response 2, or Threshold.
Solution
Do one of the following:
•If the EZ-Boom system is not controlling rate, check and adjust as necessary the
other rate controller settings.
•If the EZ-Boom system is controlling rate, check and adjust as necessary the
Response 1, Response 2, and Threshold values.
–Response 1 shows the response speed for the control valve once the Target
rate goes beyond the threshold value.
EZ-Boom 2010 System Error Messages 1
–Response 2 shows the response speed for the control valve when within the
threshold.
–Threshold shows the distance allowed from the Target rate before
switching from Response 2 to Response 1.
For a faster control valve response speed, set a higher number.
For a slower response speed, set a lower number.
Note – Trimble does not average the application rate so there will be more fluctuations.

Possible failure modes
The Control Valve closes when you enter a headland and then takes a long time to
build pressure when you leave the headland.
Solution
Do one or more of the following:
•Make sure that Close on Zero Flow is set to No.
•Make sure that the master switch stays turned on and is not turned off when
you enter a headland.
•If there is section overlap when you go into or come out of the headland, the
flow rate may be too low for the control valve. Enter a minimum flow value to
keep the valve open.
