Reset Defaults?
If the units in the first programming step have been changed, the console will ask
if you would like to reset all of the program values to the default settings for the
units selected. If you wish to reset to the defaults, use the or keys to
select “
YES” and press the key to activate the resetting process.
If you do not want to reset to the default values, select “
no” using the or
keys and press to advance to the next step.
NOTE: If you inadvertently changed the Program Units, select “no” in
this step. Advance to the Program Units step again using the key and
change back to your desired units. Select “
no” again at the Reset Defaults
step and exit the program mode by pressing and holding the key for
3 seconds.
Flow Meter or Pressure Based
Default = FLO
The 844 system can be used with either a flow meter, pressure transduce or
both. This step tells the computer which sensor you will be using on your sprayer
to control the flow regulation.
The default value is set for a “
FLO” based system using a flow meter. If this is what
you have installed on your sprayer, then press the key to advance to the
next step.
If, however, you have installed a pressure transducer instead, use the or
key to select “
PrS” for a pressure based system. Then, press the key to
advance to the next step.
If both sensors have been installed on the sprayer, this step will determine which
sensor will be used by the 844 to determine pressure/flow regulation. If “
FLO” is
selected, the flow meter will be used to control the flow and the pressure
transducer will be used only to display the actual pressure. If “
PrS” is selected,
the pressure transducer will be used to control the flow and display the actual
pressure.The flow meter signals will be ignored.
Flow meter Pulses
Default = 650
During the Flow meter Calibration Step, the symbol (flow meter turbine) will
be flashing at the top of the console display.
First, locate the factory flow meter pulse rate tag on the flow meter. If this varies
from the default value of the console, use the or keys to modify the value.
Pressing the and keys simultaneously will clear the value to zero.
In some cases, larger flow meters with small calibration numbers will include
decimals for greater accuracy. To add a decimal to the 844 calibration number,
press the Auto/Man key.
If you are not using a flow meter but are using a pressure transducer instead
and have selected “PrS” in the previous step, this step will not appear.
NOTE:This flow meter number represents the number of pulses per liter
of liquid.The 844 console makes all of the necessary conversions if using
units other than metric.The same calibration number will be used for
all units.
