Boom Control Valve Type
Default = 2 Way
While in the Boom Control Valve Type step, the symbol will be flashing at
the top of the display. The programmable information (2 Way or 3 Way) will be
displayed at the left in the console display.
This programming step is used to distinguish the type of on-off boom control
valves you have on your system.There are two types of valves that can be used,
2-way control valves or 3-way control valves.
A 2-way control valve is simply an on/off valve. Flow is either directed to the boom
section(s) or it is blocked or diverted away from the booms. A 3-way control valve is
know as a by-pass valve. Flow continuously passes through this valve.When the
valve is activated (on), flow is directed to the boom section(s). When the valve is not
activated (off), flow is directed through a bypass port, back to the supply tank.
If you are using the 3-way type of boom control valves in your system, change
the value using the or keys. Press the key to accept the value
and advance to the next programming step.
If the default value is correct, press the key to accept the value and advance
to the next programming step.
Note: If using 3-way, bypass boom control valves, refer to the instruction
manual of the valve you are using for proper calibration instructions.
Speed Sensor Calibration
Default = 250
Note: During Speed Calibration, the 844 will automatically sense whether
a Wheel Speed or Radar Speed Sensor is being used.
While in the Speed Calibration Programming Step, the symbol will be
flashing at the top of the display. The programmable value (250) will be displayed
in the lower right corner of the display.
PROXIMITY/MAGNETIC PULSES
The speed sensor needs to be calibrated in order to provide the proper speed
and area readings.The value for this step is the number of pulses generated by
the speed sensor in 300 feet (100 meters). This value can be determined by
automatic calibration while driving exactly 300 feet (100 meters), or by entering
the number manually.
Automatic Calibration:
To automatically calibrate the speed sensor, mark off a distance of exactly 300
feet (100 meters). While still in the speed calibration program step, position your
sprayer at the beginning of your 300 foot (100 meter) course and press the
and keys simultaneously to clear the contents of the display and to activate
the auto calibration mode. When the auto calibration mode has been activated,
CAL
will be displayed at the lower right of the display. Next, press the key once
to begin the calibration process. Now drive the course and the 844 will count the
pulses as the sprayer moves. The speed at which you drive over the course is
not important. Stop the sprayer at exactly 300 feet (100 meters) and press the
key to validate the number in the display. The speed sensor is now
properly calibrated.
