MPM II Electronic Seed Monitor

The electronic seed monitor system consists of aconsole with non-volatile memory which ismounted in the tractor; seed tubes with computer-ized sensors, one of which is installed in eachplanter row unit; to which the individual seedtube sensors and rotation sensors connect. Themonitor works with a magnetic (pickup) distancesensor or radar distance sensor.

Seed flow for up to 36 rows, in two 18 row sec-tions (left/right) may be monitored with one mon-itor.

The monitor system is powered by the tractor bat-tery (requires 12 volts DC). The console receivesinformation from each of the sensors and trans-lates this information.

The monitor has two backlit Liquid CrystalDisplays (LCD). The upper display shows theactive section, the number of monitored rows persection, the relative seed rate for each row (usinga bar graph display) and scrolls various alarm andwarning messages when a condition exists. Acontinuous audio alarm will sound upon systemmalfunction or underflow conditions for anymonitored row. Alarms must be acknowledgedby the user. Various warnings may sound thebuzzer or flash one or more icons. The lower display is used to display alphanumer-ic data such as row spacing, units (Metric orEnglish), speed, volume, seed population, seedspacing, field area, total area and distance sensorpulses per mile/kilometer.

The monitor will power down if no activity issensed for more than one hour. No activitymeans there has been no new seed flow and nooperator push key input.

GENERAL INFORMATION


Push keys allow the user to select or change theoperating mode, the active displays or the currentconfiguration. Depending on the operating modeor the current display selected, some keys arevalid while others are not. Each key press if validis acknowledged by a short beep and its action istaken. If the key press has no action associated,the key press is considered invalid and the userwill not get any feedback.

LCD FUNCTIONS

UPPER LCD FUNCTIONSThe monitor collects data on the planting ratesfrom all active rows and calculates an average.This average will determine the 100% mark.Seed rate for each row is then compared to theaverage value and the result is displayed on thebar graph.The information regarding each section is dis-played alternately every 5 seconds.

While operating a system with two sectionsprogrammed, one or both sections may beselected any time. When only one section isselected, the monitor calculates the average basedon the remaining active rows from that section.

Press SELECT key once to show one sec-tion. The flashing icon shows the section thatis not selected. The selected section is con-tinuously displayed on the LCD.

Press SELECT key again to activate bothsections. Ex: Press SELECT key secondtime. The information regarding each sectionwill display alternately every 5 seconds. Forsimple applications, where only one section isprogrammed, the display will automaticallylock on that section. Pressing SELECT keywill have no affect.

NOTE: When alternating between two sections,the display will lock on the section containing thefirst recognized alarm until the alarm is acknowl-edged by pressing the OK key or the alarm condi-tion is removed.

LOWER LCD FUNCTIONSThe UP and DOWN arrow keys will sequentiallychange what is being displayed on the lowerLCD. Pressing the UP or DOWN arrow keyswill move the arrow head icon (on the left andright hand side of the display) to another item.For example, if the arrow icon is pointing toSPEED, ground speed will be displayed on theLCD. Pressing the UP arrow key will move theicon to the display will change to display all theicons used to represent the current (English orMetric) measurement system.

The shortcut keys, SPEED, SEED POPULA-TION/SPACING and AREA FIELD/TOTALallow direct access to their respective displays.For example, no matter what is currently beingdisplayed on the lower LCD, pressing theSPEED key will change the display to the cur-rent speed. Pressing the SEED POPULA-TION/SPACING or AREA FIELD/TOTAL keyswill alternate between the two functions assignedto that key.

Pressing the SCAN key while displaying seedspacing or population will cause a sequential dis-play of each individual row. Pressing the SCANkey a second time will freeze the display on thecurrently displayed row. Pressing SCAN keywill restart the automatic advancing of the scanfunction.

Pressing the SCAN key while displaying speedwill cause a sequential display of speed, averageplanter population and average seed spacing.Pressing the SCAN key a second time will freezethe display on the currently displayed reading.

Press the UP or DOWN arrows to move theflashing arrow to SPEED. As the arrow iconmoves, the lower LCD will display the currentsetting of the item selected.

Press OK and the flashing arrow becomes solidand the beeper will sound. The speed constant isused to record how many pulses are generated permile (or kilometer) from the ground speed sensor.The lower LCD will display the current pulsesper mile (or kilometer), using a 6 digit, no deci-mal place format. The PULSES per MILE (orPULSES per KM) icons are turned on.

NOTE: It is highly recommended that a fieldcalibration be done to establish the PPM(Pulses per mile) number on a new machineinstallation. Several factors can affect this valuesuch as wheel slip on the magnetic distance sen-sor, mounting angle and height on the radar dis-tance\ce sensor, etc. IT IS NOT UNCOMMONFOR THE MPH ON THE MONITOR TO VARYSLIGHTLY FROM THE TRACTORSPEEDOMETER. Adjusting the PPM in themonitor to make the MPH agree can cause seri-ous errors in acre / hectare counts an populationreadings. Do field checks to verify populationsand seed spacing.

NOTE: On a new system installation, the moni-tor will default to 500 PPM. This will have to bechanged to obtain accurate readings from themonitor.

FIELD TESTIn field conditions:

•Measure 330 feet (1/16 mile) or 100 meters,(depending on your unit of measure).•Pull the tractor up to the starting line.•Press the UP and DOWN arrows at the sametime and hold them down until the CLEAR?icon is displayed and the monitor beeps sev-eral times. When the data is actually cleared,the monitor will emit a long beep and thenumber of pulses is cleared.•Drive the tractor for 330 feet (1/16 mile) or100 meters and STOP

The monitor will count the number of pulses anddisplay them.

SYSTEM ALARMS A system alarm is entered when the monitordetects a faulty sensor or one of several other com-munication faults.

The corresponding row number starts flashing andthe beeper sounds. All segments on the correspon-ding bar graph are turned off. Pushing the OK keyto acknowledge the alarm will turn the beeper off.The row number will continue to flash until thealarm condition is removed. If the monitor detectsa faulty sensor and there is no planting activitypresent, the monitor will scroll “CHECK CONNECTION”

If the distance sensor is detected as faulty, themonitor will display either PICKUP or RADAR,depending on the type of sensor installed, and theaudible alarm will sound. The user can push theOK key to acknowledge the alarm. When the dis-tance sensor is faulty, the monitor will change to abar graph only mode where the rows are still dis-played relative to each other. No area relatedinformation (speed, field acres, total acres, seedspacing or seed population) will be accumulated ordisplayed.

UNDER FLOW ALARMSIf the seed rate for one or more rows is less than55% of the calculated average, the corresponding60% segment will stay on, the corresponding rownumber starts flashing and the alarm sounds.Pushing the OK key to acknowledge the alarm willturn the alarm off. The 60% segment of the bargraph remains on and the row number continues toflash until the alarm condition is corrected.

NOTE: All alarms present within a short timebefore planting stops, are frozen on the serene andthe text LOW or FAIL will display on the LCD. Ifthe underflow is between 0%-10%, this warrants aFAIL condition. If the underflow is between 10%-55%, a LOW condition is generated. If multiplerows have an underflow condition, FAILwill display if any one or more rows is between0%-10%. This allows the user to identify and fixthe problem rows.

NOTE: This warning will not trigger unless aminimum time of continuous planting has passed.

NOTE: If all the rows show a seed rate of zero,the condition will not generate an alarm. It will beassumed the planter has stopped. The row num-bers and the bottom 60% segment will remain onfor all selected rows.

MULTIPLE ALARMSIf more than one alarm condition occurs at thesame time, pushing the OK key will acknowledgeall alarms that are currently displayed. For exam-ple, if one row on the left and one row on the rightis alarming; pushing the OK key will onlyacknowledge one of them. However, if there aretwo alarms on the lift, both alarms would beacknowledged with one push of the OK key.

WARNINGS AND ALARMS

11


SECTION NOT SELECTED WARNINGIf the monitor was programmed for two sectionsand only one is currently selected for the display(by pressing the SELECT key), the icon of thedisabled section will flash for a period of 1minute, then turn off at each power up. If seedflow is sensed in the disabled section, the icon forthat section (left or right) will begin to flash.

SEED PLANTING STOPPED WARNINGWhen the monitor detects no seed flow on allrows, the monitor will emit 3 short beeps to alertthe user. This warning will occur each time theplanter is stopped, each time the planter is raisedat the end of a row or if the mechanical drive failswhile planting.

NOTE: This warning will not trigger unless aminimum time of continuous planting has passed.

SEED COUNTING SENSOR IN CALIBRATION WARNINGAll seed counting sensors run a self calibrationsequence on power up. While in calibration thebottom segment of each corresponding bar graphwill flash if the monitor detects movement orplanting activity. If the monitor does not detectthis, the message WAIT CALIBRATION will bescrolled.

SEED COUNTING SENSOR TOODIRTY WARNINGAfter the seed counting sensors end their internalself calibration, the monitor may detect one ormore sensors are either too dirty or blocked. Ifthe monitor detects planting or movement, thecorresponding bar graph remains flashing. Themonitor will display CLEAN SENSORS on theLCD if no movement or planting is detected,prompting the user to clean the tubes. If the tubesare dirty, they will still show seed flow with lessaccuracy. If the tubes are blocked the user willget an alarm as soon as planting starts. The cor-responding bar graph will remain flashing untilthe problem is corrected and the monitor is pow-ered down and then powered back up.

LOW BATTERY WARNINGThe monitor is constantly monitoring its inputvoltage to quickly detect low power conditions.If the monitor detects that the input voltage hasdropped below 10.5V, it will display LOWPOWER on the LCD, provided that the monitordoes not detect planting.

NOTE: After the alarms have been acknowl-edged and if the alarm condition is still present,the LCD will continue to display the alarm condi-tion.
