Pub. #OM17-MSP3 Adjustable Wing Extensions This feature allows the re-positioning of the electrodes to fit various bed and crop configurations. Adjustment is made by loosening the jam nuts and set screws located on the lower front of each side of the toolbar, adjusting the toolbar wing extensions, and re-tightening the set screws. Veris suggests setting the toolbars at either the maximum or minimum setting, not at a point in between.
Pub. #OM17-MSP3 3-point Adjustment Top Link Turn the top link (Figure 60) to adjust the tilt and level the unit. This is the optimal setting for all fields types. Extending the top link will cause the rear of the unit to move down. Shortening the top link will cause the inverse. Row Unit Adjustment Adjust side depth wheels on optical row unit to allow deeper or shallower mapping. Move T-handle (Figure 61) backward for deeper depth. Depth wheels should be snug, but freely moving, against the disks.
Pub. #OM17-MSP3 Coulter Adjustment Adjusting the coulter depth is accomplished by re-mounting the coulter blade in one of the six mounting holes arranged in a staggered pattern in the coulter bracket. Figure 64 Raise unit and lower service stands before working on coulters. Do not attempt to move blade when the current or new position causes it to contact the ground during the adjustment. Be careful around the front end of row units. Row cleaner tines and coulter blades may be sharp.
Pub. #OM17-MSP3 Speed Proper field operating speed depends on field condition. Because of the importance of consistent contact, the unit must not be allowed to bounce over rough fields at high speeds. 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.
Pub. #OM17-MSP3 To help insure the quality of your data, please follow these guidelines: 1. Generate and view maps frequently, especially prior to deleting data from Instrument. 2. Listen for auditory alarm from DataLogger, indicating data collection has been interrupted. 3. View DataLogger screen or SoilViewer map frequently during data collecting; watch for: Negative readings in the Shallow and Deep or excessive noise in the OpticMapper data.
Pub. #OM17-MSP3 OM Data Quality Check depth of sensor – Make a couple of trial passes to make sure the sensor is running at the proper depth. Recommended depth is 2-3 inches. Add weights or adjust down pressure on row unit if needed Also make sure the row unit side depth wheels and disks are rotating freely, and are clear of excess mud and crop residue. For row unit adjustments see page 4-22.
Pub. #OM17-MSP3 OpticMapper Wearplate Below is a comparision of two wearplates. The left is a brand new wearplate, and the right has about 2500 acres on it.

Pub. #OM17-MSP3 Manually Operating Wash and Cycling Functions After all cables and hydraulic hoses are connected, test power to unit by turning external pH controller power switch to on position. With control switch in manual position, run wash pump briefly. If water does not flow from jets within 10 seconds, disconnect quick couplers to help pumps prime. If water doesn’t spray, but pump is running, see Troubleshooting section for instructions on priming pump.
Pub. #OM17-MSP3 Three-point Mounted Units Raise sampling mechanism to full height. Begin depth adjustment process with shank in center position (pin in one of two center holes). Adjust ratchet jack so that coulters will penetrate 1-2” deep – 21” pin-to-pin is a good starting point Adjust three-point top link to level unit when in soil.
Pub. #OM17-MSP3 Once unit is level, lower sampling mechanism completely, drive forward 10-20’ (3-6 m) to create soil core. To measure depth of soil core being collected, brush away soil from cutting shoe. Measure from soil surface to top of cutting shoe. This is the depth of sampling. To increase sampling depth, shorten ratchet jack; to decrease sampling depth, lengthen ratchet jack. Releveling unit with adjustable top link may be required.
Pub. #OM17-MSP3 Adjust scraper bracket until cutting shoe clears scraper when sampler assembly is raised completely. Figure 75 2. Adjust electrode holder: with sampling mechanism raised completely, adjust electrode holder to provide ½” (1.2 cm) clearance between it and sampling trough. Turn crank to raise or lower electrode holder Figures 76a and 76b ½” (1.2 cm) clearance between electrode holder and trough liner 3.
Pub. #OM17-MSP3 When installing BNC cover, route electrode wires under box; center box on white pad, and tighten wingnut finger tight. Keep cover installed even when electrodes are removed. When wash jets are properly aligned, overspray is minimized and water bubbles out top of empty electrode holder as shown here. Figures 78a and 78b 4. Insert pH electrodes into electrode holder. Finger-tighten plastic screws. Install BNC cover on external controller to keep moisture out of BNC connectors.
Pub. #OM17-MSP3 7. Prox sensor: The prox sensor communicates the position of the sampler assembly to the external controller for automatic cycling functions. Adjust sensor to 1/4”- 3/8” (6-9 mm) gap. Cycle unit manually to insure that this gap is maintained throughout cycling range. Red LED light should light whenever prox sensor is near metal and not light when away from metal. To view LED light, shade ambient light from prox sensor and cycle sampler assembly manually.

Pub. #OM17-MSP3 SECTION 5 Maintenance and Service Soil EC Rockshaft pivot points Each pivot (located at the left and right) contains an upper and lower 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.
Pub. #OM17-MSP3 grease zerk Figure 3 Figure 4 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. Pinch point hazard: to prevent injury, stand clear when raising or lowering any part of the Veris MSP3.
Pub. #OM17-MSP3 OpticMapper Row unit Setting Sensor Depth Refer to Figure 7 The “T” handle (1) sets sensing depth by limiting the how high the side depth gauge wheels ride relative to the opener disks. To adjust sensing depth, pull the “T” handle (1) up and back,move it forward or aft, and set it back in a different pair of holes in the scale. • For shallower sensing, move the “T” handle (1) forward. • For deeper sensing, move the “T” handle (1) back.
Pub. #OM17-MSP3 Side Gauge Wheel Adjustment Refer to Figure 10 and Figure 11 Disc-to-wheel angle and clearance ideally has the wheel just touching the disk when the wheel is raised to sensing depth (is up against the stop set by the “T” handle. The goal is to have both disks and wheels turn freely, but keep soil and trash from getting between them. These two adjustments interact with each other. Changing one requires at least checking the other.
Pub. #OM17-MSP3 • If wheel does not fall freely, loosen hex-head bolt (1) and slide wheel arm out just until wheel and arm move freely. Retighten hex-head bolt (1) according to grade: 1⁄2in Grade 5 bolt on 25 series, 75 ft-lbs (102 N-m). 1⁄2in Grade 8 bolt on 25 series, 110 ft-lbs (149 N-m). 6. Keep turning hex adjuster and moving wheel arm until the wheel is adjusted properly. When satisfied, tighten pivot bolt (2) to 110 ft-lbs (149 N-m).
Pub. #OM17-MSP3 Replacing Opening Disk 1. 2. 3. 4. Make a note of current Disk depth Remove the 5/8-11 x 4in bolt, lock washer and nut Replace disk with new disk. Reinstall disk to proper depth. Figure 16 Opening Disk lubrication The opening disks each have a grease zerk on them (right and left side). Due to the constant rotation, these should be lubricated on 80–hour intervals. Figure 17 Depth Gauge Wheels lubrication The depth gauge wheels have and upper and lower grease zerk at each pivot.
Pub. #OM17-MSP3 pH system Clean-up—ISE storage, wash If you are going to interrupt your pH mapping for 30 minutes or longer, clean off the electrodes and the electrode holder with the wash wand, and install the soaker solution container on the electrode holder.

No GPS or DGPS on display Perform Maintenance and Service Procedure #5 DataLogger locks up -SD card not installed or not formatted. See Procedure #6 to format card. -Make sure the SD card is not a SDHC card.
Pub. #OM17-MSP3 Procedure #1: OM Signal Testing Perform this test daily or every 10 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 the instrument is performing properly. The OpticMapper/EC Controller is shipped with an Instrument Test Load (Part No. 46403) that will enable you to quickly check the instrument to ensure that it is functioning properly.
Pub. #OM17-MSP3 Procedure #2: EC Signal Testing Perform this test daily or every 10 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 the instrument is performing properly. The OpticMapper/EC controller is shipped with an Instrument Test Load (Part No. 49492) that will enable you to quickly check the instrument to ensure that it is functioning properly.
Pub. #OM17-MSP3 Procedure #3: Testing Electrical Continuity Perform this test daily or every 10 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 EC Surveyor to the disk blade. Think of each coulter-electrode and its wire path as a ‘channel’.
Pub. #OM17-MSP3 Signal extension cable (from implement) Figure 3.3 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.
Procedure #4: Diagnosing and Correcting EC Signal Problems. Pub. #OM17-MSP3 Use this Troubleshooting tree to work through the system, locate the problem, and take corrective action. Figure 4.
Pub. #OM17-MSP3 Coulter Electrode FunctionsEach coulter electrode on the implement is part of a pair, and each pair has a distinct function. a) Coulters 1 & 6 are the Deep EC receptors. If you are seeing problems only with the “Deep” readings, focus on testing continuity on these two coulter-electrodes. b) Coulters 2 & 5 are the “charged” coulters that inject the voltage into the soil.
Pub. #OM17-MSP3 Figure 4.3 Testing cable at end of signal cable wiring harness Figures 4.4 ab. a. Separating sure-seal connector b. Testing terminal connector wire 4. If there is a >2 ohm reading in the signal cable harness or signal extension cable, visually inspect the wiring harness and cable extension for damage. If a visual inspection doesn’t reveal a problem, you will need to test continuity of the wiring harness and cable. You will need to ohm these cables out individually.
Pub. #OM17-MSP3 5. To ohm out the wiring harness, disconnect the serial cable extension from the implement and check continuity through the harness as shown in Figures 10a and 10b. While doing so, check the pins and the sockets of the 6-pin connector for corrosion and fit. If necessary spread the pins with a small screwdriver to tighten fit in sockets. 4 2 3 5 1 6 Figures 4.6 a and b.
Pub. #OM17-MSP3 hubcap commutator coulter spindle Figure 4.7 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.
Pub. #OM17-MSP3 2. Inspect nylon insulation slides under coulterelectrode 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 Ubolts are properly tightened to clamp mounting bracket and insulation tightly to frame. Figure 4.9 3. Disconnect signal cable from instrument or front of frame.
Pub. #OM17-MSP3 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.
Pub. #OM17-MSP3 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.
Pub. #OM17-MSP3 Procedure #6: Diagnosing GPS-related problems If you do not see a GPS, DGPS, or RTK in the upper left-hand corner of the EC Surveyor screen, you do not have GPS coming in, and no data will be sent out the serial port for logging. Figure 6.1 Insure your GPS receiver is powered and outputting only two NMEA strings GGA, and either VTG or RMC at a 1hz rate; 4800 baud, 8 data bits, no parity, 1 stop bit.
Pub. #OM17-MSP3 If it becomes necessary to send GPS data into your PC, you will use a program called HyperTerminal. This program is in all Windows software. It is designed to record serial data streaming into a serial or USB port on the computer. The purpose of this is two-fold: 1) it verifies whether your GPS and cables are delivering the proper messages, and 2) it give Veris Technologies support personnel a GPS data file to test. Here’s how to use HyperTerminal 1.
Pub. #OM17-MSP3 5. The program will then ask you for a phone number. Instead of entering a phone number, specify the proper serial port number. For example, if Com 1 of the laptop is being used, specify “Direct to Com 1” under “connect using:” at the bottom of the entry area. Figure 6.5 6. HyperTerminal will then display a configuration menu where you can specify 4800 bits per second, 8 data bits, no parity, 1 stop bit and no flow control. Figure 6.
Pub. #OM17-MSP3 7. At this point, upon clicking ok, legible strings of GPS data should begin appearing on the laptop screen. Here’s an example of a typical set of strings: $GPGGA,191528.00,3851.0333,N,09737.2342,W,2,08,1.3,372.7,M,27.3,M,10.0,0100*69 $GPRMC,191528.00,A,3851.0333,N,09737.2342,W,0.1,0.0,090998,6.3,E*48 8. If GPS data doesn’t appear, recheck the port and configuration settings to make sure they are correct.
Pub. #OM17-MSP3 Procedure #7: SD card formatting and firmware updates USING A VERIS SD CARD IN OTHER DEVICES CAN CAUSE FILE CORRUPTION. Insert a standard SD card (not SDHC type) into a SD card reader which connected to your computer. Open “My Computer” folder. Right click on the SD card icon, and select the “Format”. Figures 7.1 a and b. In the format window, click on the file system tab and select “FAT” not “FAT32”. Then press “Start”. When complete, remove the card.

Part #22611 -Check all power connections and check cables for damage before turning on pH controller.
Pub. #OM17-MSP3 Procedure #12: Checking External Controller Power The Veris pH module requires a minimum of 12 volts at all times. 12 volts at the battery terminals is NOT sufficient power for the system to function, due to the significant current draw when the pumps and solenoids are engaged. Reduced voltage can be caused by corroded or dirty terminals, and an inadequately charged battery or failure in the charging system.
Pub. #OM17-MSP3 POWER (12V) FUSE 2 (10A) and its LED 12V C 5V FUSE 1 (500 mA) and its LED Figure 12.2 External Controller circuit board (metal cover removed) 2. Turn off power to External Controller, remove clear lid and remove and replace any fuse that has failed. 3. Check voltage with a digital voltmeter at power supply connection All functions must be engaged during this test.
Pub. #OM17-MSP3 If voltage at power connector drops below 12 volts during this test: a) clean battery terminals b) check disconnect contacts c) hook power leads directly to battery—not through tractor power port d) charge battery 4. Check voltage at power cable (Figure 12.4). If 12V at cable but not on circuit board—call Veris Service Dept. Figure 12.
Pub. #OM17-MSP3 Procedure #13: Troubleshooting Sampler Cylinder Hydraulics The Veris pH module uses electro-hydraulics to perform the cycling functions. If the sampling shoe hydraulic cylinder is not functioning properly, the cause of the problem must be traced to either the electronic or the hydraulic side. This Procedure will guide you through the steps necessary to identify the problem when the sampler cylinder in manual mode is not moving or only moves in one direction.
Pub. #OM17-MSP3 SOLENOID LED’s UP 12V C 5V DOWN Figure 13.2 External Controller circuit board (metal cover removed) 3. Test voltage coming out of External Controller to solenoids. Disconnect the weather-pack connectors in line from Controller to the solenoids. Using a digital voltmeter set to read voltage, insert leads into connector coming from Controller. Activate manual raise-lower switch and read voltage. (Figure 13.3) Voltage should be 12 volts. Figure 13.
Pub. #OM17-MSP3 4. Test continuity of coil. With voltmeter set to ohms (resistance), insert both leads into the weatherpack connector leading to each solenoid. Start at the jumper wire (at first connection from external controller) and move to connector at solenoid. This tests the continuity of the signal through the coil. You should have continuity if the coil is working. Test both solenoids. Figure 13.4 Testing continuity of solenoid coil (at weather-pack connector on jumper-wire. 5.
Pub. #OM17-MSP3 Procedure #14: Troubleshooting Communication Problem Communication between the Veris Instrument and the External Controller is required for the system to initialize (sampler cylinder moves to neutral), and function. A communication failure between these components may be expressed as INIT ERR (initialization error) or COMM ERR (communication error). Follow flow chart below to address problems in their logical sequence. Figure 14.
Pub. #OM17-MSP3 Figure 14.2 Inspecting pins on communication cable 2. Testing continuity on communication cable. a) Unplug the communication cable from the DataLogger or PC. b) Bring both ends of the communication cable close enough together to reach with a voltmeter. c) Set your voltmeter to resistance (or continuity). Check continuity between the following pins: (Figure 3.
Pub. #OM17-MSP3 3. Testing continuity from the circuit board through the communication cable a) Remove the steel cover and unscrew the plastic lid from the external Controller. b) Look for the brown Molex 3-pin connector circled in Figure 14.4. The color sequence (left->right) should be white-green-black. CAREFULLY wiggle each wire to check for a loose connection. c) Check continuity between the following pins: Figure 14.
Pub. #OM17-MSP3 4. Testing that the external controller is receiving/acknowledging the command sent to it by the DataLogger or PC. a) Turn on the external pH Controller. b) Open up a HyperTerminal session on a PC: Click Start►Programs►Accessories►Communications►HyperTerminal. A new session of Hyper Terminal should open. In the box labeled “Connect using___” you will need to select the Com port you will be using. (on Windows 2000 and older: Under the Call menu, click Disconnect.
Pub. #OM17-MSP3 5. Testing that the instrument is sending the proper command to the external controller. a) Connect the DataLogger or PC to the PC using a serial cable (you will need a null modem and may need a gender changer). Turn on the DataLogger or PC and enter data acquisition. The data in Hyper Terminal should look like this $U♥♦Ç$U♥♦Ç The important letter above is the ‘U’, but the data coming up should match this character-for-character. The ‘U’ is the letter the pH Controller is looking for.
Pub. #OM17-MSP3 Procedure #15: Troubleshooting Prox Sensor The prox sensor, located on the left of the sampler shoe parallel linkage arm, is critical to the machine’s function. It informs the external controller of the sampler’s position, which allows the controller to move the sampler to the next position in the sampling/measuring sequence. If the prox sensor is not functioning properly, the entire operation will be affected. The problem may be with the Prox sensor itself or with its adjustment.
Pub. #OM17-MSP3 2. Adjust prox sensor gap if needed. Adjust sensor to 1/4”- 3/8” (6-9 mm) gap (Figure 15.3). Cycle unit manually to insure that this gap is maintained throughout cycling range. 1/4 to 3/8” gap (6-9 mm) Figure15.3 Prox sensor gap 3. Adjust prox sensor height if needed. Loosen bolt holding prox sensor arm and rotate to change height of prox sensor (Figure 15.4). Adjust prox sensor height with sampler shoe completely raised.
Pub. #OM17-MSP3 4. Check voltage to prox sensor if needed. Disconnect sure-seal connector from external controller to prox sensor. Check for 12V voltage on socket #1 and pin #3 from external controller, with power to external controller turned on (Figure 15.5). Do not short across voltmeter leads. Figure 15.
