CALCULATING "BOOM CAL" (Boom 1, Boom
2, Boom 3):
BOOM CAL is calculated by multiplying the
number of spray tips times the tip spacing. For
the Toro Pro-Control, having nozzles at 20"
spacing, the Console should be programmed as
follows:
BOOM1
CAL

BOOM2

CALCULATING "SPEED CAL"
NOTE: This SPEED CAL number is critical to
the performance of the Toro Pro Control
Spray System. Be sure tires are properly
inflated and Tank is half full before executing
the following procedure.
1. Enter a SPEED CAL number of "148" into the
key labeled:
SPEED
2. On a flat ground surface (with Tank half full),
mark off a distance of 500 feet. Verify that the
distance readout reads "0". To set the Distance
readout to "0", depress
DISTANCE
ENTER
, then depress
TIME
0
and
ENTER
. Drive vehicle straight ahead the marked
distance of 500 feet.
3. Verify that the distance readout on the
Computer Console reads "500". This distance
should be correct plus or minus 2% (in 500 feet,
this distance should be between 490 and 510 feet).
4. If the distance readout does not read "500"
(plus or minus 2%) re-calibrate SPEED CAL using
the following equation:
New SPEED CAL # =
148 x 500

Distance Readout
For example, if the vehicle travels 500 feet and the
Console reads 484 feet, correct as follows:
New SPEED CAL # =

The Flow Meter calibration number is stamped
on the white tag attached to each Flow Meter.
There is a gallon calibration number to be used
for gallons per acre or gallons per 1000 and also
a liter calibration number to be used for liters per
hectare.
CALCULATING "VALVE CAL":

1. The initial Valve calibration number for
VALVE CAL IS 023. This number is
recommended for most spray applications. The
VALVE CAL number is used to control response
of the hydraulic Control Valve to the change in
vehicle speed. After operating the system, you
may desire to refine this number. See definitions
below:
Valve Speed digit -
Controls response time of Control Valve motor.
CAUTION: Running the Control Valve too fast
(number greater than zero) will cause the sys-
tem to oscillate.
Range: 0 to 9 0 - Slow, 9 - Fast
Brake Point Digit Percent -
Sets the point at which the Control Valve motor
begins braking, so as not to over shoot the de-
sired rate. Digit is percent away from target rate.
Range: 0 to 9 0 = 5%, 1 = 10% 9 = 90%
Dead=Band Digit -
Allowable difference between target and actual
application rate, where rate correction is not
performed.
Range: 1 to 9 1 = 1%, 0 = 9%
NOTE: For Application Rates below 20 gallons
per acre .50 gallons per 1000 sq. ft. or 190 liters/
hectare (i.e. Toro Number 95-9221 Yellow Nozzles),
Valve Cal or 043 or 063 will stabilize control
response.
