All SprayMate
TM
XRS consoles, flowmeters and servo 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 a test light or meter, 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 Speed Cal.
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.
DISTANCE COUNT IS INACCURATE
Speed Cal was incorrectly measured or entered. Review
calibration, re-adjust and test.
AREA COUNT IS INACCURATE
Implement width or Speed Cal was measured 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 boom
sections.) Verify accuracy with formula:
Acres = Distance x Width in feet/43560
Hectares = Distance x Width in meters/10,000
NO READOUT OF GALLONS (LITERS), OR GALLONS
(LITERS) PER MINUTE
Check to see that the sprayer pump and equipment are
operating properly. If liquid is moving through the line, check
the flow sensor to be sure it is screwed all the way into the
flowmeter.
Check to see that a FLOW CAL number has been entered. Also
check cable for breaks or incomplete connection.
If the flowmeter is new or has not been used for a long period
of time, the turbine may be sticky. Flushing the system out
with water should make the turbine spin freely.
Flow rate may be too low to register a reading, or foreign
material may be lodged in the flowmeter.
SECTION SHUT-OFF
If you are in AUTO with no speed, all sections will shut-off.
TOTAL LIQUID USED IS INACCURATE
This may result from an incorrectly-entered “FLOW CAL”
value. Check the number stamped on the flowmeter tag,
and be sure the number is entered correctly. If the meter
has been used for some time, wear may have changed the
Flow Cal value. See Fine-Tuning Flowmeter Calibration in
Appendix D.
Check the mounting position of the flowmeter. With lower
flow rates, the meter should be mounted vertically. Also
check to see that the flow sensor is screwed all the way into
the flowmeter.
Other causes may be inaccurate sprayer tank markings, a
flow rate too low to register, or foreign material lodged in
the flowmeter.
CONSOLE IS ERRATIC IN OPERATION
If you have a two-way radio, it may be mounted too close
to the console. Keep all SprayMate
TM
XRS cables away from
the radio, its antenna and power cable.
Ignition wires could cause the console to malfunction.
Keep SprayMate
TM
XRS 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
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 CONTROL SPEED setting by 1
(range is -12 to +3).
DISPLAYED MEASUREMENTS DO NOT MAKE SENSE
The console may be in the incorrect measurement mode
(English or metric).
DISPLAY READS “99999”
DISTANCE, AREA, and VOLUME counters read 99999 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 Calibration. If using a
slow valve (4 seconds or more, close to open) increase the
CONTROL SPEED setting.
