844E Sprayer Crontrol
98-70006 R3
CONDITION
POSSIBLE CAUSE
SOLUTION
E
Speed sensor installed incorrectly
One or more of the wheel sensor
magnets are not consistently sending a
pulse to the monitor.
The distance between the sensor and
the magnets is incorrect. Ground debris
can accidentally move the sensor out of
position. The red LED on the back side
of the sensor should be lit when placed
within the correct distance form the
magnets.
A proximity sensor has an orange LED
on the top of the sensor that should be lit
when placed within the correct distance
from the sensing surface.
F
Radar installed incorrectly
Precise installation of the Radar is critical
to it working correctly. Thoroughly review
the manual provided with the Radar
sensor you are using.

No regulation in Auto Mode
A
No speed sensing
Check speed sensor to ensure it is
sending pulses to the controller. Check
the Calibrate Speed section in the
System Setup Mode on pages 17-20 of
the 844 Installation Manual to ensure
speed sensors are correctly calibrated.
B
Regulating valve malfunction
Check wiring from controller to the
regulating valve. Make sure there is
voltage to the regulating valve.
Both wires leading to the regulating valve
are 12V(+). With the Master Switch on,
and the console set to MAN Mode when
either the
or
key is pushed, the
appropriate wire goes to ground (–) to
complete the circuit.
