All ProPlant consoles, motor and control valves are tested
prior to packaging, so unless there has been damage in
shipment you can be confident that everything will be
operational when you receive it.
However, if you do encounter a problem that appears to be
related to equipment failure, PLEASE DO NOT OPEN THE
CONSOLE. Your system is protected by a warranty, and
Micro-Trak will gladly correct any defect.
Many problems are the result of mistakes in installation or
operation. Before returning any parts for service, carefully
check your installation and review the operating instructions.
For easy-to-follow guidelines, refer to the troubleshooting
section which follows.
CONSOLE APPEARS DEAD
Using your test light, check for 12 volts at the power source.
Also check for damaged power cable or reversed terminals.
(Console requires 12 volts for proper operation). Check
connections of ignition or power switch.
SPEED IS ALWAYS ZERO OR ERRATIC
Check for properly calibrated wheel circumference.
Review speed sensor installation. Check for proper mounting,
alignment and spacing of speed sensor in relationship to
magnet assembly. Make sure magnet polarities are alternated.
Also check cable for breaks or incomplete connection. For
more suggestions on solutions to speed problems see
page 39.
DISTANCE COUNT IS INACCURATE
Speed Cal was incorrectly entered. Review calibration,
re-adjust and test.
AREA COUNT IS INACCURATE
Implement width or wheel circumference was measured
incorrectly or programmed incorrectly. Go back through
the original procedures, make changes, and test for acre
(hectare) count again.
(Make sure no width is entered for
unused sections.)
Verify accuracy with formula:
Acres = Distance x Width in feet/43560
Hectares = Distance x Width in meters/10,000
SECTION SHUT-OFF
If you are in AUTO with no speed, the section motors will
shut-off.
CONSOLE IS ERRATIC IN OPERATION
If you have a two-way radio, it may be mounted too close to
the console. Keep all ProPlant cables away from the radio, its
antenna and power cable.
Ignition wires may be causing the console to malfunction.
Keep ProPlant cables away from ignition wires, or install
ignition suppressor.
Reroute all cable away from electric solenoids, air conditioning
clutches and similar equipment.
Check the CONTROL SPEED calibration number in Special
Calibration. If the RATE tends to overshoot or oscillate, the
CONTROL SPEED setting may be too high for the control
valve being used; reduce the VALVE SPEED setting by 1
(range is -5 to +3).
DISPLAYED MEASUREMENTS DO NOT MAKE SENSE
The console may be in the incorrect measurement mode
(English or metric). See page 29 for instructions.
DISPLAY READS “OFL”
DISTANCE, AREA, and SEEDS counters read OFL when they
have exceeded their maximum count. Reset to zero to
resume counting.
SYSTEM OPERATION (CONTROL) IS SLUGGISH IN
AUTOMATIC MODE
Check the CONTROL SPEED setting in Special Calibration.
If using a slow valve (4 seconds or more, open to close)
increase the VALVE SPEED setting.
