CLN Message - Clean
When a Seed Sensor reports weak eye strength, CLN followed by the Seed Sensor number is displayed three times; the audible alarm will sound. When a CLN alarm occurs, look for a complete blockage at the opener of the identified Seed Sensor or buildup on the indicated Seed Sensor eyes.

DEF Message - Default
During power up, if the Monitor Head determines the saved calibration values have been corrupted, DEF is displayed. Press the up arrow button to restore normal operation. If this occurs, check the power cable connections, and redo the entire Calibration process of the monitor.

E1 Message
An E1 message indicates a critical failure has occurred in the Monitor Head. There is nothing the user can do to restore normal operation. If an E1 message occurs, send the Monitor Head in to be repaired or replaced.

End Message
After the Seed Sensor loop has been enumerated, End is displayed then Seed Rate mode is selected. If an END message does not occur on power up, look for an Err message causing the Seed Sensor loop to be renumerated.

Err Message
If a complete loop of Seed Sensors is not reported to the Monitor Head, Err followed by the Seed Sensor number that is not reporting to the Monitor Head is displayed; the audible alarm will sound. The Err message remains until a complete loop of Seed Sensors is established. When an Err message occurs, look for a disconnected or damaged Sensor Loop cable, Seed Sensor, or Extension cable at the identified Seed Sensor location.

HI Message - High Seed Rate
When a Seed Sensor reports a seed rate greater than the Seed Rate mode high alarm value, HI followed by the Seed Sensor number is displayed three times; audible alarm will sound. When a HI message occurs, look for a corresponding LO message on another Seed Sensor.

LO Message - Low Seed Rate
When a Seed Sensor reports a seed rate less than the Seed Rate mode low alarm value, LO followed by the Seed Sensor number is displayed three times; the audible alarm will sound. When a LO message occurs, look for a partial or complete blockage at either the opener or manifold of the identified seed sensor.

LP Message - Low Power
If the Monitor Head detects less than 10 volts DC on power up, LP is displayed. None of the modes of operation are available, the buttons do not function, and the LP message remains until a voltage above 10 volts DC is detected. When a LP message occurs, look at the power cable of the Monitor Head and the electrical system.

OFL Message - Overflow
When a signal higher than the maximum allowable signal is reported, or an accumulated value increases above the maximum total, OFL is displayed. The OFL message remains until the reported signal is below the maximum, or the accumulated value is cleared. Press and hold the down arrow button to clear an accumulated value.

--- Message - Blockage
This message only occurs in Seed Scan mode. If a Seed Sensor reports a seed rate below the seeds per second set by the sensitivity value, and the speed is 1.0mph or morel --- followed by the Seed Sensor number is displayed. An audible alarm will occur before the --- message is displayed.

Monitor Head
Situation: When the Power button is pressed, the display remains blank and no button lights come on.
Solution:
1. Confirm that the power cable is connected correctly
2. Check for 12 volts at the red wire, and ground at the black wire
3. Disconnect the Monitor Head power cable from the 12 volt source for 30 seconds, then reconnect
4. If the display remains blank, send in the Monitor Head for repair.

Situation: The Monitor Head only displays LP
Solution:
1. Check the voltage between the red and black wires of the power cable. At least 10 volts is required to run the system. If the voltage is less than 10 volts, check the battery, alternator and wiring.
2. If the voltage is over 10 volts, send in the Monitor Head for repair.

Situation: None of the buttons on the Monitor Head work
Solution:
1. Check the displayed message, if Err or LP are displayed; this will occur.
2. Disconnect the Monitor Head power cable from the 12 volt source for 30 seconds then reconnect.
3. If the buttons still do not function, send in the Monitor Head for repair or replace it

Situation: The optional sensors are not used, but the Aux1, Aux2 or Fan button light is always flashing and the audible alarm sounds.
Solution:
1. Ensure the Cal values for Aux1, Aux2, and Fan mode are set to zero.

Situation: The Monitor Head only displays Art then Err then 1.
Solution:
1. Check the cables. The Main Harness Extension, Y-Cable, Sensor Loop Cables and Seed Sensor #1 must all be connected. If the Monitor Head does not detect Seed Sensors, this will occur.
2. Bypass Seed Sensor #1 by connecting Seed Sensor #2 to the Sensor Loop Cable from the Y-cable. If the message is no longer displayed, replace Seen Sensor #1.
3. Connect a Seed Sensor directly to the Y-Cable's male Sensor Loop Cable. If Err then 2 is displayed (normal diagnostic message), replace the Sensor Loop Cable between the Y-Cable and Seed Sensor #1.
4. Turn the power off. Connect the Y-Cable directly to the Monitor Head with the Sensor Loop Cables connected together. Turn the power on. The Monitor should automatically power up in Speed Mode. If the display shows Err then 1, send the Monitor Head and Y-Cable in for repair.
5. If the previous test was OK, there is at least one sensor in the loop that is causing problems with the communication system. Bypass all but the first group or tower of sensors; if the Err 1 message is gone, add in the 2nd tower of sensors. If the Err 1 message is still present, then split the first tower in half and add only the first half of the tower to the sensor loop. Continue this process until all the problem sensors have been located and all the towers are included in the sensor loop.

Situation: The Area shown in Area mode never increases. The Area button light is flashing.
Solution:
1. The Area button light will only flash when using a Work Switch. With the Work Switch Remote, check the AUX1 or AUX2 calibration values. Be sure that the work switch is calibrated correctly.

Situation: Seed Rate and Seed Scan mode cannot be selected. The Speed Mode button light comes on.
Solution:
1. Check that the Y-Cable’s Sensor Loop Cables are not connected together. This selects Speed Mode automatically at power up; Seed Scan and Seed Rate modes are not available.

Situation: The Monitor Head always displays DEF when power is turned on.
Solution:
1. This indicates calibration values have been corrupted. Press the up arrow button to restore defaults.
2. Check the voltage between the red and black Monitor Head power wires. There should be over 10 volts.
3. Recalibrate the system.
4. If the message is still displayed, send the Monitor Head in for repair.

Seed Sensors
Situation: The Monitor Head always displays Cln and various numbers
Solution:
1. Note the indicated numbers. The Cln message indicates that the “eyes” (optical detectors) in the Seed Sensor tube are dirty. Clean the indicated Seed Sensors with warm water, and a plastic bristle pipe brush.
2. If the Seed Sensor still causes a Cln message, replace it.
Note:Some seed innoculants quickly build up inside the sensor. The solution may be to switch brands.

Situation: The Monitor Head never indicates any alarms on any of the Seed Sensors.
Solution:
1. Ensure that the sensitivity value and the low seed rate alarm values are not set to zero.
2. Ensure the high seed rate alarm value is not set to zero.
3. Ensure the Work Switch is calibrated correctly. The Area button light should flash when raised.
4. Check the reported ground speed; Speed mode. If the ground speed is below 1.0 MPH (1.6 Km/h), no alarms will occur.

Situation: The speed value is not constant – and jumps up and down frequently.
Solution:
1. Check that the speed sensor targets are evenly spaced.
2. Check that the radar is aimed properly

Situation:The Monitor Head always displays Err then a number higher than 1.
Solution:
1. Make note of the number. Check the Sensor Loop Cables and Extensions.
2. Bypass the Seed Sensor indicated. Connect the cables of the bypassed sensor to each other to keep the connections clean. If normal operation begins, replace the bypassed Seed Sensor.
3. If the same Err is still displayed, connect the sensor normally. Bypass the next lower Seed Sensor. If normal operation begins, replace the bypassed Seed Sensor.
4. If the same Err message is still displayed, connect the sensor normally. Bypass the next higher Seed Sensor. If normal operation begins, replace the bypassed Seed Sensor.
5. If a Sensor Loop Cable connects the Seed Sensors indicated, swap the Sensor Loop Cable. If normal operation begins, replace the Sensor Loop Cable.
Note: As a temporary solution, bypass the failed Seed Sensor. The Seed Sensor count will be one less.

Situation: The Monitor Head indicates a low seed rate alarm, but the Seed Sensor is not blocked
Solution:
1. Check the Low Seed Rate Alarm. The setting must be lower than the currently displayed seed rate.

Situation: The reported seed rate is not correct.
Solution:
1. A Speed Sensor or Radar Adapter is required for Seed Rate mode to function accurately. If Test Speed is used, the seed rate may not be accurate.
2. Check the Seed Count Multiplier value has been set; default value is 1.000
3. Check the Speed displayed; it should match the tractor
4. Check that Area is accumulating properly. If the reported area coverage is incorrect, the seed rate will not be accurate.
5. Check the row count value. If the row count value is incorrect, the seed rate may not be accurate.

Situation: When Seed Rate mode is selected only OFL is displayed
Solution:
1. Check the Seed Count Multiplier value. The default is 1.000
2. Check the application rate. If the seeds per acre or hectare is more than 99.99 million this will occur.
3. Check all the calibration values related to calculating the Seed Rate (Speed, Width and Row Count)

Situation: Certain Seed Sensors cause a low seed rate alarm, but the displayed seed rate in Seed Rate mode is higher than the Seed Rate Low Alarm value.
Solution:
1. Check for a restriction in the hose, opener, manifold or tower of the Seed Sensor(s) in alarm.
2. The displayed seed rate is the average for the entire machine. Many Seed Sensors could be reporting a lower seed rate. Reduce the Seed Rate Low Alarm value.

Situation: Seed Rate mode reports a seed rate even when the air seeder is completely stopped and the fan is turned off.
Solution:
1. Activate Test Speed on systems with a Speed sensor or Radar adapter. Test Speed is activated by pressing the speed button & the down arrow button and setting the speed value to greater than 1.0 mph (1.6 Kph)
2. Set the high alarm value to 1
3. Bypass the Seed Sensors identified with a HI seed rate alarm. If normal operation begins, replace the bypassed seed sensor(s).

Situation: Seed Rate mode displays 0
Solution:
1. A ground speed sensor must be reported in Speed mode. Verify that the speed sensor type and location calibration has been completed.
2. When using Test Speed, make sure the set test speed is not zero.
3. Check the circumference value, implement width, row count and Seed Rate Multiplier calibrations
4. Check that the power light at the Speed Sensor or Radar Adapter is on. Swap a minidin cable and Speed Sensor if the light is not on. If a speed is still not displayed, send in the Monitor Head for repair.

Situation: Seed Scan only indicates a blockage while viewing Seed Scan
Solution:
1. The blockage alarm message (--- followed by a Seed Sensor number) only occurs while in Seed Scan mode. While in any other mode of operation, low seed rate alarm message (LO followed by a Seed Sensor number) is displayed for blockage.

Situation: When Seed Scan mode is selected the display always shows 0
Solution:
1. Check that the sensitivity value is not zero. If the sensitivity is set to zero, the Seed Scan mode is disabled.

Situation: Sensors give false blockage readings when the sun is high(mid-day)
Solution:
1. Tape approximately 6 inches of hose on either side of the sensor to prevent the sunlight from interfering with the infrared beams.

Speed Sensor or Radar
Situation: Speed and Dist mode are operating correctly, but Area mode does not accumulate
Solution:
1. Check the width value. With a width value of zero, no area will be reported
2. Check that the Work Switch is calibrated properly; the Area button light should flash when raised

Situation: Speed and Dist mode are operating correctly, but the Area mode accumulation is incorrect.
Solution:
1. Without a Work Switch, Area always accumulates, even when turning around at the head lands. If the area accumulation is too high, and the calibration is correct, consider using a work switch.
2. Area mode does not account for any implement overlap. This can be corrected by decreasing the width value by an expected overlap amount.
Warning:Adjusting the width value reduces the accuracy of Seed Rate mode by changing the calculated number of Seed Sensors

Situation: After calibrating the Speed Sensor, Speed, Area and Dist mode are not correct
Solution:
1. Check the selected units of measurement. For example, if the units are set to Metric (SI) and the Speed sensor calibration was done assuming English (US) measurement, this problem will occur.
2. Redo the Speed sensor calibration using a different method
3. Check the Speed sensor is within the recommended distance from the target; magnetic is ½” (13mm) and metal is 1/8” (3mm). Make sure all the targets are evenly spaced.
4. Check that the Speed Sensor power light is constantly on. An intermittent connection could cause this problem. Check connections; swap the sensor and minidin cable.
5. If the problem persists, send the Monitor Head for repair.

Situation: The displayed ground speed flashes in Speed mode.
Solution:
1. This is normal for speeds below 1.0 mph (1.6 Kph)
2. Test speed will overwrite any other speed input. If using a speed sensor or radar adapter, test speed must be set to 0
3. Refer to the manuals Calibrations section for information on how to change the speed sensor location
4. If the problem persists, send the Monitor Head for repair.

Situation: When Speed mode is selected only OFL is displayed
Solution:
1. Check the Speed sensor calibration. If the reported ground speed is over 100 miles per hour (km/h) this will occur. Recalibrate the Speed sensor. (Radar or GPS equivalent output to rdr setting uses a circumference value of approximately 19.0”, and gnd setting of 0.6”)

Situation: When the Monitor Head was turned on, the accumulated values in Area and Dist mode are not the same as when the system was last used.
Solution:
1. Check the voltage between the red and black wires of the power cable. If the voltage is low when turned off, this problem could occur.
2. Check the tractor’s battery cables, connection to the starter, and alternator. Electrical surges due to a faulty electrical system can cause this problem.
3. Check that the red wire is not connected to the starting solenoid terminal.
4. If the problem persists, send the Monitor Head for repair.

Situation: When Speed mode is selected, ground speed is 0
Solution:
1. Check that the Speed sensor or Radar Adapter is connected
2. Check that the test speed value is not at zero if a speed sensor or radar adapter is not connected
3. Check that the circumference value is not set to zero
4. If the radar is also used by the tractor, be sure that the tractor indicates speed properly
5. Check the Speed Sensor targets
6. Check the power light; Swap the speed sensor or radar adapter and minidin cable
7. If the problem persists, send the Monitor Head for repair

Bin Sensor
Situation: The air cart tank went empty, but the Bin sensor never alarmed
Solution:
1. Check that the sensor cable is still connecting the Bin Sensor to the Sensor Adapter. Since the default Cal value for Aux1 and Aux2 mode is zero, a disconnected Bin sensor will never cause an alarm.
2. Check the Work Switch calibration. The Area button light should flash when raised
3. Check the ground speed displayed. If the ground speed is below 1 mile per hour, no alarms will occur. If Test Speed is being used, increase Test Speed to the actual seeding speed.
4. Swap the Bin Sensor with another Bin Sensor at the Sensor Adapter, if available. If the problem moves, replace the Bin Sensor and minidin cable.
5. If the problem persists, send the Monitor Head for repair.

Situation: When Aux1 or Aux 2 mode is selected nothing but 0 is shown.
Solution:
1. With no optional sensors connected, nothing but zero is displayed.
2. Bin sensors report an audio alarm when the air cart tank goes empty. The display does not change.

Fan Sensor
Situation: Fan mode showed the air seeder fan stop turning, but there was no alarm.
Solution:
1. Check the Fan mode low alarm value. If the low alarm is set to zero, no alarms are issued.
2. If the Sensor Adapter power light is not on, check the connections to the Sensor Adapter.
3. Connect the Sensor Adapter directly to the Monitor Head. If the Sensor Adapter power light is not on, replace the Sensor Adapter; this assumes the Seed Sensors were recognized by the Monitor Head.

Situation: When Fan mode is selected, RPM is 0
Solution:
1. Check the Fan mode Cal value. If the Cal value is set to zero, no RPM will be reported.
2. Check the targets’ metal targets must be within 1/8” (3mm) of the sensor.
3. Check the connections; Check if the Fan Sensor power light is on; Swap the Fan Sensor and minidin cables
4. Swap the Fan Sensor with a Shaft Sensor at the Sensor Adapter, if available. If the problem moves, replace the Fan Sensor and minidin cable
5. If the Sensor Adapter power light is not on, check the connections to the Sensor Adapter.
6. Connect the Sensor Adapter directly to the Monitor Head. If the Sensor Adapter power light is not on, replace the Sensor Adapter; this assumes the Seed Sensors were recognized by the Monitor Head.

Situation: Fan mode display an ROM, but is always in alarm
Solution:
1. Check the Fan mode low alarm value. The low alarm value must be less than the operating RPM of the air seeder fan.
2. Check that the Fan mode Cal value is set to the correct number of targets.

Situation: The reported Fan RPM is not correct, or unstable.
Solution:
1. The Fan mode Cal value must be set to the exact number of Fan Sensor targets. If the Cal value is incorrect, an incorrect RPM will be displayed.
2. Check the Fan Sensor targets; they must be less than 1/8” (3mm) from the sensor. The targets must be evenly spaced. For example, if 1 bolt head is missing on a 3 bolt fan hub, setting the number of targets to 2 will cause erratic readings.
3. Check the connections; Check if the Fan Sensor power light is constantly on; an intermittent power connection will show erratic fan RPM readings.

Situation: When Fan mode is selected only OFL is displayed
Solution:
1. Check the Fan sensor calibration. If the fan RPM would be over 9990 this will occur.

Shaft Sensor
Situation: Aux1 or Aux2 mode showed the monitored shaft stop turning, but there was no alarm.
Solution:
1. Check the low alarm value for Aux1 or Aux2 mode. If the low alarm is set to zero, no alarms are issued.
2. Check the Work Switch calibration. The Area button light should flash when raised.
3. Check the ground speed displayed. If the ground speed is below 1 mph (1.6 Km/h), no alarms will occur. If Test Speed is being used, increase the Test Speed.

Situation: The Shaft Speed on Aux1 or Aux2 mode is always 0
Solution:
1. Check the Aux1 or Aux2 mode Cal value. If the Cal value is set to zero, no RPM will be reported.
2. Check the connections; Check if the Shaft Sensor power light is on; Swap the Shaft Sensor and minidin cables.
3. Check the targets; magnetic targets must be within ½” (13mm); metal targets within 1/8” (3mm).
4. Swap the Shaft Sensor with another Shaft Sensor or a Fan Sensor at the Sensor Adapter, if available. If the problem moves, replace the Shaft Sensor and minidin cable.
5. If the Sensor Adapter power light is not on, check the Main Harness Extension connections to the Sensor Adapter.
6. Connect the Sensor Adapter directly to the Monitor Head. If the Sensor Adapter power light is not on, replace the Sensor Adapter; this assumes the Seed Sensors were recognized by the Monitor Head.

Situation: The reported Shaft RPM is not correct, or unstable
Solution:
1. The Aux1 or Aux2 mode Cal value must be set to the exact number of Shaft Sensor targets. If the Cal value is incorrect, an incorrect RPM will be displayed.
2. Check the Shaft Sensor targets; they must be evenly spaced. For example, if 1 magnet is missing where 4 magnets were installed on a square shaft, setting the number of targets to 3 will cause erratic readings.
3. Check the connections; Check if the Shaft Sensor power light is constantly on; An intermittent power connection will show erratic RPM readings.

Situation: The Shaft sensor connected to Aux1 or Aux2 mode displays an RPM, but is always in alarm
Solution:
1. Check the low alarm value to Aux1 or Aux2 mode. The low alarm value must be less than the operating RPM of the monitor shaft.
2. Check the Cal value for Aux1 or Aux2 mode. The Cal value must be set to the exact number of Shaft sensor targets.

Situation: When Aux1 or Aux2 mode is selected, only OFL is displayed
Solution:
1. Check the Shaft Sensor calibration. If the shaft RPM would be over 999.9 this will occur.

Work Switch (Manual and Remote)
Situation: The Area button light flashes when the implement is in the ground, and Area mode only accumulates when the implement is raised
Solution:
1. Be sure that the work switch is calibrated correctly.

Situation: The Area button never flashes, and Area mode always accumulates.
Solution:
1. Check that the Work Switch is calibrated correctly.
2. Check the Work Switch Remote Target. The magnet must move at least 1” (25mm) away from the Work Switch Remote (implement up) and move within ½” (13mm) (implement down).
2. Check the connections; Check if the Work Switch Remote power light is on; Swap the Work Switch Remote and minidin cables.
3. If the Sensor Adapter power light is not on, check the Main Harness Extension connections to the Sensor Adapter.
4. Connect the Sensor Adapter directly to the Monitor Head. If the Sensor Adapter power light is not on, replace the Sensor Adapter. The seed sensor loop must be complete

Situation: The Area button always flashes, and Area mode never accumulates
Solution:
1. The Work Switch must be calibrated correctly. If using a Manual Work Switch; and it is not detecting the button press, either the Manual Work Switch or the Monitor Head is defective. Return both for repair.
2. Check the Work Switch Remote target. The magnet must move at least 1” (25mm) away from the Work Switch Remote (implement up) and move within ½” (13mm) (implement down).
3. Check the connections; Check if the Work Switch Remote power light is on; Swap the Work Switch Remote and minidin cables.
4. Connect the Sensor Adapter directly to the Monitor Head. If the Sensor Adapter power light is not on, replace the Sensor Adapter. The seed sensor loop must be complete.
