Advanced Menu
The Advanced Menu screens include this information:
Setup
Fig. 17:
System Gain
The System Gain screen (1) lets you make changes to the system pressure control.
Range: 1 to 20
System Gain is the first pressure control parameter in the display menu system. System Gain changes the total
response of system according to the same ratio between the individual P Gain and I Gain values. It is the first
menu item to utilize when tuning the pressure control.
Increasing the System Gain makes the system react faster to pressure changes.
Decreasing the System Gain makes system react slower to pressure changes.
P Gain
The P Gain screen (2) lets you change the value.
Range: 2.00 to 8.5
P (Proportional) gain is the second pressure tuning parameter in the display menu. Proportional gain determines
the initial speed at which display drives the duty cycle toward the target value. Stabilize an oscillating system by
selecting a lower number. Speed up a sluggish system by selecting a higher number.
©
2019 Capstan Ag Systems, Inc. 28 EVO Spray
TM
I Gain
The I Gain screen (3) lets you change the value.
Range: 0.05 to 0.35
I (Integral) Gain, the third pressure tuning parameter in the display, determines the acceleration driving duty
cycle to the target value. To stabilize an oscillating system, use a lower number. To speed up a sluggish system,
use a higher number.
Run/Hold Delay
The Run/Hold Delay screen (4) lets you change the delay when the display starts at a preset value (50% or the
last known duty cycle) allowing the rate controller to stabilize before making larger pressure control changes.
Range: 0 to 6
When the boom is turned on and the run/hold signal is returned, the display will begin to control pressure by
first resuming the pulsing at the previous duty cycle before the boom was shutoff.
The Hold will show in the Diagnostics area on the main operating screen, to alert the operator that the
initialization delay has been activated.
The start-up delay time is equal to the run/hold delay time. This allows the flow control system to resume
control and attain rate stability. Once the delay period has elapsed, the display will resume pressure control.
Setup
The diagnostic readout area will read Hold and count down the seconds to alert the operator that the Run/Hold
Delay has been activated. When the hold count down is finished, the display will read Run in diagnostics area.
At this point, the display is controlling pressure once again.
Low Pressure Shutoff
The Low Pressure Shutoff screen (5) lets you change when the system turns off the nozzle valves when the
pressure decreases.
Range: Off or 8 psi
This feature is intended to duplicate the effect of the nozzle drip checks found on sprayers. To alert the operator
that the low pressure shutoff feature has been activated, low PSI shutoff will appear in the diagnostic readout
area.
When the pressure rises above 12 PSI again, the display will pulse at 50% duty cycle for the start-up delay
period and then will resume pressure control.
When set to Off, the display will maintain a minimum duty cycle percentage, equal to the pulse frequency,
regardless of either low or zero pressure.
Pwm Frequency
The Pwm Frequency screen (6) lets you change the value.
Range: 3 to 30 Hz
CapstanAG does not recommend pulse frequencies slower than 10 Hz in sprayer applications.

separate pressure sensors, such as between the display pressure reading and the rate controller pressure display
from a secondary pressure sensor.
Range: -10 to 10
Note: The system requires a greater quality pressure sensor relative to pressure sensors which only report a
screen value. In most cases, the adjustment will be correcting the value to the least accurate sensor.
Sensor volt min
The Sensor volt min screen (4) lets you change the minimum voltage of the pressure sensor.
Range: 0.5 to 1.0
If you are using a CapstanAG™ pressure sensor leave the default value of 0.5. Change the value as needed if
you are using another type of pressure sensor.

CAUTION: Before operation or service to the system, read and understand the machine’s operator
manual and the system operator manual. Chemical residue may be present on/in the OEM equipment.
Use the correct personal protective equipment.
Before servicing the system or plumbing components, release the pressure and empty any product from the
system and liquid delivery lines.
Jump Start, Weld On, or Charge the Machine
If jump starting the machine, make sure that you trip the circuit breaker to prevent damage to the system.
If charging the machine’s batteries or welding on the machine, trip the circuit breaker.
Inspect the System
• Inspect the hoses for cuts, nicks, or abrasions before each use. Replace any damaged hoses immediately.
• Make sure that the strainers are clean.
• Make sure that all hoses and wiring are secure.
• Do a check for loose hoses, mounting hardware, and other components. Tighten if necessary.
• Do a check for damaged or missing decals. Replace if necessary.
Maintenance
Clean the System
• Thoroughly clean the system after each use.
• Avoid high-pressure spray when cleaning the spray system components, valves, and wiring connectors.
Storage of the System
Thoroughly clean the implement and the system before any long storage.
Winterize for Storage
Do not use fertilizer to winterize! The use of fertilizer to winterize will cause internal damage to the nozzle
valves.
Thoroughly clean the spray system before winter storage.
Flush the spray system with clean water.
Winterize the spray system with RV antifreeze for winter storage. Proper winterizing of the machine with a
CapstanAG system installed on it is essential. Make sure that the booms are completely full of antifreeze at
100% strength and that the solenoids are pulsed (sprayed) for a few minutes to make sure that the antifreeze
remaining in the solenoids is at full strength.

Recommended Guidelines for Maintenance/Service
When servicing a system, CapstanAG recommends doing these:
• Do the baseline service checks and verify the original setup values in this manual.
• Identify individual performance problems. Evaluate possible causes and corrections for performance
issues.
• Troubleshoot individual components and replace if needed.
Important: The primary service tool will be a multimeter that can measure voltage and resistance (ohms).
Baseline Evaluation Process
1.
Make sure that the voltage readings are correct.
2.
Do a visual check of all wire connections, harnesses, and connectors. Make sure that there are no loose,
broken, or damaged parts.
3.
Make sure that the correct tip size is used for the application.
4.
Make sure that the liquid product plumbing and the strainer(s) are clean.
5.
Do a like component swap test to see if the failure follows the component.
6.
Repair or replace any damaged components.
7.
Do the system tests.
Maintenance
See the system testing information in this manual.
Nozzle Valves
Plugged nozzle valves can be classified into two categories:
• Plunger blockage
• Plunger stuck
Plunger blockage results when larger debris catches between the orifice and plunger seal. This is the smallest
flow passage within the nozzle valve.
Stuck plungers result when smaller debris collects around the barrel of the plunger and binds the plunger in
place. Symptoms of a blocked or stuck plunger are:
• Constant application
• Leaking when the nozzle is shut off
• No application
Note: Pinched or split O-rings will also cause nozzles to drip when shutoff.
Note: Operating a plugged nozzle valve for extended periods of time may result in a nozzle valve coil failure.
Immediately clean any plugged nozzle valves.

Clean the Nozzle Valve(s)
Warning: Chemical residues may be present in the agricultural equipment. Always use the proper
personal equipment to avoid personal injury.
1.
Release pressure from the system before servicing.
2.
Clean the system before installation or service of the fittings, hoses, valves, or nozzles.
Fig. 28:
3.
Use pliers around the flybody (1) to hold the assembly with the coil harness facing the ground.
4.
Rotate the coil (2) counter-clockwise to remove the coil from the valve body.
5.

Plunger Seal Inspection
Maintenance
Fig. 29:
After extended use, the plunger seal will wear a groove (1) where the seal impacts the hard orifice seat. Replace
plunger if worn or damaged.
As the groove deepens the pressure capacity of the valve will decrease until the pressure capacity interferes with
the operating pressure of the system.
The result is erratic pulsing, often described as “flickering.” The system will operate normally at lower
pressures until replacement parts can be installed. High operating pressures and abrasive chemicals will
accelerate the wear of the plunger seal material.

Chapter 9: Troubleshooting
Troubleshooting Charts
When troubleshooting the EVO™ system start with these:
1.
Use the battery harness fuses to isolate half of the system. This will help focus on the half of the system
that has the issue. The fuse located on the left trunk corresponds to the power to CAN X harness left trunk
connections.
2.
When there is a CAN issue, isolate half of the system to start looking for the issue by disconnecting the left
or right trunk connection.
3.
Once the side of the system has been determined (left or right trunk), use the daisy chain of CAN extension
harnesses to finish isolating the issue. Disconnect the connections except for the center module and harness.
Start connecting the modules back together one at a time until the error shows again. When the error shows
again, you have found the section with the problem.

Interchangeable Components
The system includes a number of multiple parts:
• Nozzle valves
• Boom and extension harnesses
• Electronic control modules
When troubleshooting failed components, it can be helpful to replace the failed part with a working part at
another location. If the problem follows the failed part to the new location, repair or replace the failed part.
If the problem does not follow the failed part, then the problem is likely elsewhere in the system, and other
troubleshooting means may be followed.
Note: Use caution when interchanging failed components as in rare cases the failed component may cause
other components to fail at the new location.
Coil Test
Coil failures are often the result of two factors:
• Extended valve use with a plugged nozzle
• Extended use in corrosive environments
Troubleshooting
Recommendation: Clean any plugged nozzle valves immediately.
Recommendation: Rinse the inside of the booms, and wash the outside of the coils with clean water as often
as practical.
Use a voltmeter to measure the ohms of resistance across pins A and B on the coil connector.
Notice:
Correct resistance is:
• 7-watt coils resistance—21 ohms to 23.5 ohms
• 12-watt coils resistance—10 ohms to 11.5 ohms
If correct resistance is not found:
• Clean the connector terminals and retest
• Replace the coil

Battery Voltage Test
Troubleshooting
Fig. 39:
Disconnect the display harness (12-pin connector) on the back of the cab display.
• With the engine of the machine running, use a voltmeter to observe that there is a 13.5 VDC between pin
1 and pin 2.
• With the engine of the machine off, there is a 12.0 VDC between pin 1 and pin 2.
Make sure that the polarity is accurate by looking at the positive voltage when the red (positive) probe is
connected to pin 1, and the black (negative) probe is connected to pin 2.
If there is no voltage present between pin 1 and pin 2, do a check of:
• The 5 A in-line Fuse on the pin 1 battery wire.
• The 2 (20 A fuses) located next to the battery connection point.
• The system battery harness connections.
• The condition of the battery and the alternator.

Do a Check of the System Load Capacity
1.
Start the engine of the machine.
2.
Turn on the cab display and all of the boom sections.
3.
Turn on all of the electrical loads, including the air conditioning, foam marker monitors, etc.
4.
See what the voltage readout on the cab display is on the Diagnostics screen.
The nozzle valves operate best at 12 VDC or higher. Using less than 12 VDC will result in reduced pressure
capacity. This will often result in erratic nozzle pulsing, sometimes described as flickering. Also, do a check of
the nozzle valves for worn plunger seals.
If low voltage is observed, do a check of:
• The battery terminals and clean as necessary
• The condition of the battery
• The condition of the alternator
• The condition of the connections
• Check and clean the battery terminals.
• Check the battery condition.
Troubleshooting
• Check the alternator condition.
• Check the condition of the connections and retest.

Pressure Sensor Signal Test
Troubleshooting
Fig. 40:
Disconnect the pressure sensor (1) from the pressure sensor harness (2). Connect one end of the pressure sensor
breakout harness diagnostic tool (3) into the pressure sensor shroud connector. Connect the other end into the
pressure sensor harness tower connector.
With the engine running and the system is turned on, use the rate controller to establish 50 psi on the pressure
gauge.
Use a voltmeter to observe that there is 2.75 VDC between the black and white wires on the pressure sensor
breakout harness.
Using the rate controller, adjust the pressure to 100 psi. The voltmeter should read 5.0 VDC.
If accurate voltage is not present:
• Verify the accuracy of the pressure gauge on the sprayer.
• Do a check of the power to the pressure sensor.
• Use the serial diagnostics to check the pressure sensor calibration.
• Replace the pressure sensor.

Power to the Pressure Sensor Input Test
Troubleshooting
Fig. 41:
Disconnect the pressure sensor (1) from the pressure sensor harness (2). Connect one end of the pressure sensor
breakout harness diagnostic tool (3) into the pressure sensor shroud connector. Connect the other end into the
pressure sensor harness tower connector.
Use a voltmeter to observe that there is13.5 VDC between the red and black wire on the pressure sensor\
breakout harness with the engine running, or 12.0 VDC without the engine running.
Be sure the polarity is accurate by observing that there is positive voltage when the red (positive) probe is
connected to the red pressure sensor breakout harness wire, and the black (negative) probe is connected to the
black pressure sensor breakout harness wire.
If no voltage is present, do a check of:
• The fuse located at the battery
• The battery connections
• The condition of the battery
• The condition of the alternator
