Important! Read the following SAFETY PROCEDURES before operating the Veris system:

• Read and understand all instructions on safety decals

• Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard by
relieving pressure before disconnecting hydraulic lines. Use a piece of paper or card-board, NOT BODY
PARTS, to check for suspected leaks.

• Wear protective gloves and safety glasses or goggles when working with hydraulic and high-pressure
wash systems.

• If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed

within a few hours or gangrene may result.

• Pinch point hazard: to prevent injury, stand clear when raising or lowering any part of the Veris implement.

• Install all transport locks before transporting or working underneath.

• Detach and store implements in an area where children normally do not play. Secure implement by using

blocks and supports.

• Read Operations Manual before operating machine

• Review safety instructions with operators before operating machine and at least annually

• Never stand on or use tire as a step

• Do not tow the implement on public roads without the road-kit light package, or without the proper safety

equipment and licensing as required by your State Department of Transportation. Always use safety chain.

• Riders obstruct the operator’s view. They could be struck by foreign objects or thrown from the

Electronics Overview and Set-up

The U3 electronics kit includes the items shown below

Keep all diagnostics and operations manual with system when mapping.

The supplied GPS (Figure 2a or 2b) is configured to
operate with the U3 electronics. Note: V.Sense
controllers manufactured before 9/01/2016 are equipped
with the external GPS shown in Figure 2a.

The use of any other GPS requires the correct settings. The
GPS needs to output only two NEMA strings(GGA and VTG
OR RMC). The system will not run with more than two
strings. The strings need to output at 4800 baud and 1Hz

Electronic Configurations

The U3 platform is comprised of two controllers: V.Sense and U3 pH The V.Sense controller generates the
EC and Optical signals, and communicates with the U3 pH controller, and the PC (SoilViewer software)
either via serial or Bluetooth. The SoilViewer software reads the status of the GPS and U3 pH controller
signal inputs (ex. up or down proximity sensors), and initiates the pH cycling when the cycle criteria are met.

The SoilViewer mapping software will automatically detect the Bluetooth or Serial port the controller is
connected to, and begin communicating. If the V.Sense controller is not detected, the software will wait 45
seconds for the connection of the electronics and search again; this will repeat until the connection is
established. If the connection is not found, unplug the serial or USB cable, restart the PC, reboot the
controllers, then and reconnect USB cable to the PC. If using Bluetooth, exit the software, and ensure the
controller is paired per procedure 11.

The conditions for mapping and storing EC and Optical data are as follows. The unit must be traveling a
speed greater than 1 mph, there must be a GPS signal received, the OM/EC Comm Light must be green,
indicating the PC and V.Sense controller are communicating properly, and the EC 0-2 value has to be
greater than -1. When all these conditions are met, the Saving Data light will be green and the EC and
Optical points will be mapped.

The pH readings on the display show continuously what each electrode is reading. When logging sensor
data, the hydraulic cylinder will hold the electrodes against the soil and record a pH reading once a
particular settle method (see settle method criteria) has been met. The minimum recording time is 7
seconds; the maximum time (default 12 seconds) is determined in the pH controller settings menu. If the
reading takes longer than 10 seconds to settle, a warning will appear that indicates the number of seconds
the reading has required to settle. When the maximum log time is reached, the hydraulic cylinder will
automatically retract and wash the electrodes. For additional information on the pH sampling sequence see
the Recording UTV pH Data section.

Before mapping, perform the OM and pH system checks to ensure proper sensor operation.

If mapping has stopped, files may be appended by selecting a previous file when prompted at the startup of
the software.

Settle Method Criteria

The electrodes are pre rinsed with water before cycling into the soil. This removes any dust which may
have built up on the electrodes, and establishes moisture for the pH sensor to properly function. A
measurement time of 7-15 seconds is required to allow the pH reading to move from the water pH to a
stabilized soil pH reading. The following settling methods are employed to allow the pH cycle to as quickly
as possible; while also alerting the user to potential issues.

Quick Settle (QS): Electrodes met a superior settle criterion in 8 seconds or less. The reading is stored,
and the cycle continues.

Standard Settle (S): Electrodes met standard settle criteria in less than the maximum settle time (default
12 seconds). The settled reading is recorded in the data file, and the cycle continues.

Time Out (TO): Electrodes didn’t settle within the maximum settle time. The reading was recorded;
however, one or both the electrodes didn’t meet the standard settle criteria. If 40% of your sensor data falls

in the category, consider increasing your maximum settle time.
Time Out Redo (TORD): Electrodes took longer than the maximum settle time, and the reading had

excessive noise. The software will prompt the user to pull forward 10 feet and redo the sample. No data
point will be logged in file.

This example shows the pH sampling pattern on a 200’ by 200’ (61 m) grid, which is slightly denser than a 1
acre (.4 ha) grid. The EC-OM transects are 50 ft (15 m) apart and the pH samples are collected from every
fourth transect.

Wash Time – Amount of time wash water sprays
the electrodes at the end of a pH cycle. Default is 1
second. If issues arise with electrode cleaning in
sticky soils, increase to 2 or 3 seconds)
Max Measurement time – Maximum time for
electrodes to record before rejecting sample. The
range of this value can be 12-20 seconds. Default
is 12 seconds. If over 30% of readings time out
before settling, increase time to 15-18 seconds.
Min Distance between samples -- This sets he
minimum sampling density in automatic mode. This
threshold keeps the sampler from cycling close to
an existing pH sample point. Default is 10 meters.
Target distance between samples (m) – Distance
at which the software will flag the operator to stop
and take a sample in Automatic mode. Default is
65 meters, which equates to about 1 point per acre.

SoilViewer Warning Messages

There are warning signals programmed into the SoilViewer to warn the operator that data are not being
recorded, so that corrective action can be taken. If data aren’t being recorded, a warning beep will sound
from the computer, and the text indicator of the data that is missing information will blink. For example, if
the DGPS isn’t being received (or the NMEA string containing speed) the Fix indicator text will blink. If EC
values are negative, they will also blink. Additional messages may appear in the Warning Message Box as
follows:

display the following screen:

Figure 34

If an ‘X’ is displayed beside one or both electrodes’ scores, this indicates that one or both of the

electrodes did not perform well enough for continued reliable use. The electrode(s) responsible for
failed system check should be removed and either buffed lightly with emery cloth or sandpaper, or
replaced and the system check procedure repeated.

Tip: It is still important to perform the system check at least daily, since this process is important to
test electrode quality.

Section 5: Field Operations

Field Operations: Implement

Checking Electrical Signal Continuity and Electrode Isolation

It is recommended that you perform the Electrical Signal Continuity and Electrode Isolation test
procedure before first field use (see Service Procedure 3). While these tests were made at the
factory, there is the possibility a problem developed during shipping. Performing these tests on the
new implement allows you to get familiar with the process under ideal conditions. It is advised that
you perform this test on a routine basis (every 10 hours of data collection) to ensure you are
obtaining reliable data. KEEP OHMMETER, TEST LOAD AND TEST BOX WITH THE MACHINE

AT ALL TIMES.
Setting Operating Depth

Begin field operation by lowering unit into soil. For good electrical conductivity, all coulter
electrodes must be in direct contact with moist soil, at all times and in every region of the field. An
initial depth of 1-2” (2.5-5 cm) is recommended. To insure this depth is consistently achieved, 400­600 lbs. (180-275 kg) of additional weight are normally required on non-pH units. Veris offers
optional weights, or they can be supplied by the customer. Do not adjust the tension on the coulter
electrode springs to increase soil contact or penetration. They are pre-set at the factory with the
proper tension. Note: all depth settings recommendations are for normal conditions. Local

soil conditions may require deeper settings (if soils are dry) or shallower settings (if soils
are wet or sticky).

Field Condition

Field should be in a uniform state. Mapping after intensive primary tillage is not recommended. The soil
must have a minimum of 20% available water, and cannot be frozen. If rocky conditions exist, slow down
and make sure rock guards are in place

Figure 1
Turn the top link to adjust the tilt so that the unit runs level. This is the optimum setting for all field

conditions. Extending the top link will cause the rear of the unit to tip backward. Shortening the top link will
cause the unit to tip forward.

Speed

Proper field operating speed depends on field conditions. Because of the importance of consistent contact,
the unit must not be allowed to bounce over rough fields at high speeds.

Top Link

Pub# OM20-U3-pH

5-2

Pulling Vehicle

The implement may be pulled with a variety of vehicles: UTV, 40 hp tractor or a 4WD pickup.

• Be very careful when mapping stubble fields with a gasoline engine. Be prepared if
a fire starts.

Swath width and Navigation

Setting the swath width and navigation system is at the discretion of the customer. A 50’-75’ (15-23 m)
swath works well in most areas. Several methods of navigation are possible: following previous crop rows,
swath guidance, or auto-steer. While it is important to map in a consistent pattern, it isn’t absolutely critical
that each pass be exactly the same distance from the previous pass.

To help insure the quality of your data, please follow these guidelines:

1. View SoilViewer map frequently during data collecting; watch for:

• Negative EC readings or excessive noise in the data.

• EC readings should fluctuate gradually as you drive across the field, relating to
soil changes. If readings change erratically, or show values not typical of soil
conductivity in the area—such as >100, perform tests 4 and 5 below.

• Watch for streaks, stripes, unnatural patterns, and missing data points.

2. Perform Signal test (Procedure #3):

• at least once a day during mapping season

• every 10 hours of mapping

• after extended periods of non-use

• after replacing or repairing coulter-electrode components or wiring

• whenever readings are questionable

3. Keep all electrical connections dirt and moisture-free

4. Limit speeds in rough or rocky field conditions. This will improve data quality, and will also lengthen the

service life of the implement components. NEVER EXCEED 15 M.P.H. FIELD SPEED.

Pub# OM20-U3-pH

5-3

OM Data Quality

Monitoring the window – This can be done by watching OM readings at row ends when unit is raised, if they
are not within 10% of the initial raised readings check windows for mud, smearing, and/or window breakage.

Varying Field Conditions – In order to have high data quality the field conditions need to be the same for an
entire data set. Any of the following can affect data quality: variances in soil moisture do to different
management conditions (ex. tillage), change in down pressure or depth gauge wheel setting. If conditions
change within a field, start a new file.

The map example in figure 2 shows mapping on two separate days; the left portion of the map was mapped
under on a different day under different soil conditions. This part of the field should have been mapped on a
separate file. This same effect can occur also by adjusting down pressure or sensor depth.

Setting Optical Row Unit Down pressure

The spring down pressure settings on the optical row unit are determined by the firmness of the soil being
mapped.

For soft soils, low to medium spring pressure should be adequate.
In firm soil conditions, down pressure may need to be added.

Adjust by rocking adjuster rearward with a 1 1/8” wrench and clicking into higher lower position. Fully

rearward is maximum down pressure and fully forward is minimum.

Setting Row Cleaner Depth

The row cleaner mounted on the coulter operating ahead of the OM/pH runner is critical in removing crop
residue from the runner path. It is fitted with an adjustment screw to limit the down float of the row cleaner
fingers. Once you have set the operational depth of the implement, adjust the adjustment screw until the
fingers are lightly contacting the soil. (figure 6)

If the fingers are moving too much soil, adjust the screw downward to raise them up.
If the fingers are not clearing enough residue, screw upward.

Field Operations: pH Sampler

While the EC and OM sensors are continuously logging data when the unit is in the soil and moving, the pH
sampler will only cycle when the unit is in “Automatic” mode and the unit is fully stopped.

Important Note—

a) Keep the electrodes from freezing.
b) Always make sure the electrodes are in the raised position before mapping.

Prior to mapping, there are several items you need to check concerning the pH sampler.

1) If the electrodes have not been installed, install by loosening the allen-head pinch bolts on the

sampler and installing the electrodes.
Slide electrodes down all the way.

2) Connect the front electrode to pH 1 and the rear to pH 2 (figure 8).

3) Turn on controller and switch to Manual. LED’s will indicate when the switch is active. (figure 8)

4) Fill wash tank with water and make sure that valve handle is pointed toward supply hose. This is a

three position valve. Forward as show in Figure 9 is “on”. Vertical is “off” and rearward is for tank
drainage.

Note: You may have to bleed the air from the system to allow the pump to properly prime. This is

accomplished by removing one of the wash hoses by releasing the auto-lock fitting. Simultaneously push
down on lock collar and pull up to release hose. Press manual wash switch until pump is primed, and push
hose back into auto-lock fitting. (Figure 10)

5) Raise sampler into top position and press manual wash switch. Check to see if both electrodes are

being sprayed correctly for cleaning. (figure 11)

6) If necessary, adjust by loosening set screws and re-adjusting. (figure 12)

7) Raise sampler to top position, switch to Automatic, and you are ready to begin mapping.

Sampler will now lower every time you stop in the field. Information on sampling density and swath

Winterization and Storage

During periods when the temperature is below freezing overnight, you must take precautions to protect the
wash system and ISE electrodes.

1) Turn off tank valve and manually depress wash switch until no more water appears from the wash

jets. If for longer term, rotate valve rearward and drain tank.

2) Remove drain plug from bottom of filter mounted under wash tank.

3 Remove wash hoses at auto-lock fittings and blow out check valves and jets with compressed air.

4) Remove pH electrodes from unit.

Procedure #3: Testing Electrical Continuity

Perform this test daily or every 20 hours of data collection to ensure you are obtaining reliable data, and
whenever EC data is questionable.

The purpose of this test is to insure that each coulter-electrode has an uninterrupted signal path from the
V.Sense controller to the disk blade. Think of each coulter-electrode and its wire path as a ‘channel’. On a
U3000, there are 4 signal channels that must be clear and isolated from one another. You will first test the
complete pathway for each channel—each coulter-electrode. One easy-to-take reading for each channel
tests the cable, wiring harness, and each coulter-electrode and disk blade. If no problems surface during
this test, there is no need to test individual components. This test should take only a couple of minutes to
perform.

To perform this test, you will need the EC Signal Test Box (part # 223707) and an ohmmeter (sometimes
referred to as a multi-meter or voltmeter). Make sure the meter is set to ohms, Ω. If a range of ohms is
available, choose the lowest setting--ohms rather than kilo or mega ohms. If unfamiliar with ‘ohming-out’ or
resistance testing, make a few trial tests before performing the Veris signal test procedure. Touching the
meter leads together will display a zero resistance reading, touching two places on the same piece of metal
will produce a nearly zero reading, touching nothing will produce an OL (overload or over limit) reading—
meaning complete resistance, and no continuity.

Figure 3.1
Remove the signal cable from the V.Sense Controller and

connect it to the terminal on the test box. This cable attaches to
the signal cable end and allows you to position the Signal Test
Box in close proximity to the coulter-electrodes.

Firmly press one lead of the ohmmeter to the #1 coulter blade edge (left hand, standing behind the unit) and
the other lead to the #1 terminal on the test box. Maintain firm pressure on the ohmmeter lead touching the
disk blade. A reading of less than 2 ohms is normal. Rotate blade ¼ of a turn back and forth as you view
the ohmmeter. Any jump in the readings above 2 ohms indicates a problem.

Continue to check each coulter electrode in succession, left to right.
If any coulter electrode exhibits no continuity or resistance higher than 2 ohms, refer to Procedure #4
Diagnosing EC Signal Problems.

Coulter Electrode Functions-

Each coulter electrode on the implement is part of a pair, and each pair has a distinct function.

a) Coulters 2 & 3 are the 0-2’ receptors.
b) Coulters 1 & 4 are the “charged” coulters that inject the voltage into the soil. If you are getting no

(or intermittent) readings -- continuity to one of these two coulter-electrodes is likely the cause.

If the continuity ohm test indicates a problem on a channel, you will need to determine where the
interruption is located. Listed below are detailed instructions on how to determine exactly where a
continuity or isolation problem is located:

A. Testing Cable and Wiring continuity:

1. Once a high resistance reading on a channel is confirmed, determine whether the problem is in the
wiring or in the coulter-electrode. To test all cable and wiring, place one ohmmeter lead in the Test
Box terminal pin for that channel and the other on the corresponding coulter wire terminal bolt.
Grasp connector and move back and forth during this test – vibration from rough fields can weaken
the contacts, causing intermittent breaks in continuity during operation that might not show up in a
static test. Repeat process on all coulter-electrodes.

2. If you see <2 ohms on all, test the coulter electrodes as explained in B below.

3. If you see a > 2ohms reading on any channel, separate weather pack connector and insert one
ohmmeter lead in the end of wiring harness and the other lead in the corresponding terminal on the
Test Box. If reading is < 2 ohms at that point, the problem is not with the wiring harness or signal
cable extension. It is most likely in the terminal connector wire. Check resistance in it by placing
one ohmmeter lead on the coulter wire terminal bolt and the other lead in the end of the terminal
wire socket. Replace connector wire (PN 14226) as necessary.

Pub# OM20-U3-pH

4. To ohm out the wiring harness, disconnect from the implement and check continuity through the
harness as shown in Figure 4.4. While doing so, check the pins and the sockets of the 12-pin
connector for corrosion and fit.

Pub# OM20-U3-pH

6-8

Figures 4.4 and 4.5. Checking continuity of signal harness, with one ohmmeter lead contacting pins in
connector and other lead contacting corresponding coulter-electrode.

Note: intermittent electrical problems are difficult to diagnose. Flex wiring and connectors while checking
continuity.

B. Testing Coulter-Electrode continuity

1. Place ohmmeter lead on terminal wire bolt and other lead on disk blade. Rotate blade ¼ turn. If
readings are consistently above 2 ohms, check for excessive corrosion at the coulter blade mounting
bolts, or the terminal located near the coulter pivot. Make sure that high ohm readings are not due to
poor contact between blade and ohmmeter lead. Re-test holding lead firmly against edge of blade,
removing rust or paint if necessary.

2. If ohms jump over 2 ohms when the blade is rotated, and you were careful to maintain good contact
between the lead and the blade, the problem is likely inside the hub. Because electrical signals
cannot be sent consistently through the coulter bearing, Veris has designed a more reliable path for
the EC signal to travel. A special hub with a spring plunger presses against the spindle of the
coulter, serving as a commutator. Shown below is a cut-away view of the hubcap and plunger
assembly. When ohm readings jump during blade rotation, it is due to the greased rollers on the
bearing making intermittent and inconsistent contact. See Maintenance and Service procedure #5:
Spring Plunger adjustment and replacement on adjusting and replacing spring plungers.

and Current Pins

Figure 4.6

C. Testing Coulter-Electrode isolation
If continuity tests show no excessive resistance on any channel, yet erratic soil EC readings continue, or if

EC readings do not drop to –1 when unit is out of the soil, it is possible that the channels are not isolated.
This could be the result of a pinched wiring cable, causing channels to short out. Or, one of the coulter­electrodes is no longer insulated properly from the frame or adjacent coulter-electrodes.

1. If EC readings do not drop to –1 when unit is raised, disconnect
signal cable extension from implement. If readings don’t drop to

-1, the problem is with the signal cable extension. If readings
show -1, re-insert the signal cable extension into the implement.
Disconnect the terminal connector wire from each coulter
electrode. If readings don’t drop to –1, the problem is with the
wiring harness. If this is the case, you should replace the wiring
harness. If readings do drop, re-insert the signal cable extension
into the implement. The problem is with one or more of the
coulter-electrodes. Proceed as follows:

Figure 4.7

2. Inspect nylon insulation slides under coulter-electrode
mounting brackets. These nylon insulators may become
worn or brittle, or may slip out from under mounting
bracket. Repair and replace as necessary. Make sure that
all electrode coulter U-bolts are properly tightened to
clamp mounting bracket and insulation tightly to frame.

Figure 4.8

3. Disconnect signal cable from instrument or front of frame. Check so see that no metal part of the any
coulter electrode is in contact with the implement frame. This may be by visual inspection or by
connecting one lead of an ohmmeter to the individual coulter electrode, and the other to a grounded
fastener on the frame. If the coulter electrode is properly isolated, no reading will be obtained. Make
sure that all electrode coulter clamp bolts are properly tightened to prevent lateral movement of the
coulter electrode.

Figure 4.9

4. Wet soil on the toolbar could be a pathway for the EC signal to short. Test coulter-to-coulter and
coulter-to-frame isolation by checking resistance between coulter-electrodes. Any continuity from
one coulter to another is not acceptable. Remove buildup of wet soil, especially if is bridges across
insulation slides. It may be necessary to remove coulter mounting brackets and clean toolbar, if
problem persists.

to short.

Procedure #5 Spring Plunger adjustment and replacement

The spring plungers are located in the center of each coulter electrode hub cap, and are vital to maintain
good continuity through the coulter hub bearings. They are factory preset, and should not need routine
adjustment. If a continuity test shows abnormally high resistance, the plungers should be checked. This
may be performed in the following manner:

1) Check coulter hub bearing preload by grasping coulter blade and pushing from
side to side. If there is any noticeable movement, bearing preload is incorrect, or
bearings are failing --and this can damage the spring plunger ; see procedure #8
for adjustment or replacement.

2) Remove the 3/8” allen head set screw.

3) Remove the plunger by turning counter-clockwise.

4) Depress the spring loaded tip on a hard surface to determine if

plunger has adequate tension and can move freely.

5) If the plunger will not move freely, replace. Coat the threads with di-electric silicone
grease before installation.

6) If the plunger appears to be in good working order, reinstall in the hub, and adjust
until it bottoms against the spindle end. Rotate 1/2 turn backward to allow
adequate clearance. Improper adjustment will result in premature failure (too little
tolerance) or poor continuity (too much tolerance). See Figure 3.12 below to view
proper clearance.

7) Reinstall locking set screw and tighten firmly on top of plunger. The top of the
setscrew should be even with the face of the hub. If not, remove and adjust the
plunger inward or outward as necessary.

8) Re-test coulter electrode continuity

Figure 5.1
In some cases, you may have to remove the hub cap to service the spring plunger, if the

plunger is rusted in the cap, or if the readings are still unsatisfactory with the new plunger
installed.

Pub# OM20-U3-pH

6-12

Procedure:

1) Remove hub cap by turning clockwise with a pipe wrench or large adjustable
wrench – these caps have left hand thread to prevent loosening during field
rotation.

2) If plunger is frozen in cap, remove allen head set screw on top of plunger and
apply penetrating oil on both sides of plunger. Let this stand for a few minutes and
try to remove. If it will not back out with allen wrench, lock vise grips on the inside
portion and turn out through inside of hub.

3) Clean all hub cap surfaces, install new o-ring, coat plunger and set screw with di­electric grease and install as outlined above.

4) Re-install hub cap and tighten firmly. You may have to re-set the plunger to
compensate for the reduced length on the newly ground spindle. Re-adjust as
outlined above.

Note: If you are still unable to obtain favorable resistance readings, check for excessive corrosion at the
coulter blade mounting bolts, or the terminal located near the coulter pivot.

Procedure #6: Diagnosing GPS-related problems

If you do not see a GPS, DGPS, or RTK on SoilViewer screen, you do not have GPS coming in, and no
data will be recorded.

Figure 6.1(No GPS) Figure 6.2 (With DGPS fix)
Insure your GPS receiver is powered and outputting NMEA strings GGA, and either VTG or RMC at a 1hz

rate; 4800 baud, 8 data bits, no parity, 1 stop bit. Verify that your GPS cable is sending GPS data through
pin 2, pin 5 is ground, and no other pins have signal or power on them. The most common issue is hz rate.
If the GPS has been used for lightbar guidance it may have been set to a 5 or 10 hz rate. It will need to be
changed to 1 hz in order for the EC Surveyor to accept it.

Shown below is a Troubleshooting tree for diagnosing GPS signal problems. It is not meant to replace your
GPS receiver user manual—it merely shows how to determine if your receiver is sending the GPS signal
that the EC Surveyor needs.

Procedure #7: Lubrication

• Pinch point hazard: to prevent injury, stand clear when raising or lowering any part of the Veris U3000.
Disengage automatic cycling function before working around unit.

• Install all transport locks before transporting or working underneath.

Rockshaft pivot points – Each pivot (located at the left and right) contains

a grease zerk. Due to the limited motion of the rockshaft, these should be
lubricated on 20-hour intervals. This may vary based on the number of times
the unit is raised and lowered.

Figure 7.1

Electrode coulters Pivot --In all but the most extremely rocky conditions, the coulter electrodes should not
flex in the field, thus minimal movement will occur at the pivot. 80-hour intervals are typically sufficient.

Hubs --Use good quality wheel bearing or lithium grease for lubrication, but we suggest that you grease the
hubs sparingly. Over-lubricating the hub will result in pre-mature seal failure, and an excessive amount of
grease in the hub cap/commutator. On an interval of 150 hours, 1-2 strokes of grease should be sufficient.

Procedure #8: Bearing Repair and Replacement

The coulter electrode hubs operate in a significantly harsh environment, and annual inspection is of utmost
importance. The double-lip seals are designed to keep grease in, and contaminates out, but they are the
cause of practically all hub failures. It is advisable to disassemble, clean and repair annually. To perform
this maintenance, do the following:

1) Remove hub cap by turning in a clockwise direction (left-hand thread
prevents loosening in operation).

2) Remove cotter pin, castle nut, thrust washer, and remove hub.

3) Remove outer bearing and knock out inner bearing and both races (cups)

4) Veris recommends that you purchase our Coulter Hub Repair Kit (PN 32641) that
includes new bearings, races, seal, o-ring and cotter pin.

5) Thoroughly wash hub in solvent and dry.

6) Spindle end may need grinding—see spring plunger replacement Procedure #5

7) Reassemble and adjust bearing pre-load by fully tightening spindle nut, then
backing off until you can turn the hub fairly easily with one hand– normally this
involves backing off 1- 2 slots on the castle nut, and inserting cotter pin.
Excessive pre-load may cause plugging in extremely loose soil conditions, and
excessive endplay may damage the spring plunger. Hub should have no side play
when assembled, but should turn with little resistance. Drive round end of cotter
pin firmly into nut, and bend upper portion of cotter pin upward and trim of excess
length of both top and bottom with cutting pliers. Do not bend cotter pin over
the end of spindle as it will interfere with spring plunger.

8) Fill hub via grease zerk until grease pushes through outer bearing.

9) Install hub cap by threading counter-clockwise on the hub. Check to make sure
that hub still rotates freely. If not, the cotter pin may too long, and is contacting
hubcap –remove cap and check cotter pin length.

10) Adjust spring plunger clearance as mentioned in Procedure #5.

Procedure # 12 U Series pH troubleshooting

1. Unit doesn’t cycle in automatic mode.

-Does ‘Fix Window’ show GPS, DGPS, or RTK status?

-Solution: connect GPS to system; check baud and herz rate; settings

-Is EC/OM communication light green, showing communication between V.Sense controller and
PC?

-Solution: establish communication between the PC and controller; may require reconnecting and/or
rebooting both devices

-Are EC 0-2’ readings positive?
Solution: move ahead a short distance to allow EC coulters to penetrate

-Are you more than the minimum sample distance from previous sample?

-Solution: move ahead at least the minimum sample distance (user selectable under Controller
Settings)

-Does State window have any text in it? System will not cycle again until it has completed the current
cycle

-Solution: Depending on the state indicated, you may need to manually reset pH system by turning
both controllers off and on again; may need to move sampler shoe to up position using manual
mode

-Does sampler move in manual mode?
If yes but not in automatic mode, check items above: GPS, communication, etc

2. Sampler doesn’t move in manual mode.
Solution: check power to controller and battery connections to pulling vehicle; if ok, additional

troubleshooting with voltmeter will be required.

-Does the sampler only move one direction? Remove hydraulic cover and check LED’s on lower hyd
block DIN connections. Left is Up Sol, Right is down Sol.

3. pH electrodes not cleaning properly;

-check jets manually; are they both spraying, are they aligned?

-if pump not working, prime pump as outlined in pH Operations section; clean filter

-lengthen wash cycle (see Controller setup)

4. pH readings not agreeing with each other

-manually wash electrodes for several seconds; do they agree when clean?

-are both electrodes at same depth? Has one or both moved up into holder?

-perform 4 and 7 pH buffer solution test

5. pH readings taking too long to settle

-check soil/electrode contact; is i-Scan runner penetrating deep enough? Is crop residue entering
slot measurement area?

-Check movement of pH electrode parallel linkage; does it move freely and have full travel?

Pub# OM20-U3-pH

6-22

-Inspect rear of shoe for mud buildup; could be preventing full electrode depth

-Are both electrodes bottomed out on electrode holder?

-Is the U3 running parallel to the ground? if tipped forward, electrodes may not contact soil correctly.
Also check that there is ample spring pressure on electrode holder.
