5. The console will now prompt for a "VALVE CAL"
value to be entered.
NOTE: When entering any calibration figures during
the calibration process the
be depressed momentarily to display the "E" enter
symbol. The "E" indicates the console is ready to
accept a calibration figure. After keying in a figure the
[ENTER] key must be depressed again to lock the
new value in before moving on to the next step.
STEP 6 - VALVE CAL
The [VALVE CAL] value is located on the side of the
flow control valve together with the
"FAST CLOSE VALVES" have a value of [743].
To enter the value calibration figure:
1. Depress the [ENTER] key to display the "E" enter
symbol.
2. Key in the appropriate [VALVE CAL] calibration
number as printed on the side of the flow control
valve.
3. After keying in the appropriate valve calibration
number depress the [ENTER] key again to lock
it in.
4. The console will now prompt for a [RATE CAL]
number to be entered.
STEP 7 - APPLICATION RATE
[RATE CAL] is the rate (litres/hectare) desired for
the particular application
NOTE: Before entering an application rate consult
the nozzle application chart (in the operators
manual or the Tee Jet catalogue) to ensure the rate
is within the speed and pressure capabilities of the
no les fitted to the boom.
To enter a [RATE CAL]:
1. Depress the [ENTER] key to display the "E" enter
symbol.
2. Key in the desired application rate (i.e. 50 L/ha).
3. Depress [ENTER] again to lock it in.
4. The console will now prompt for a "SPEED
SENSOR TYPE" to be entered
NOTE: If the console detects the presence of
a 2nd product it will automatically interrupt the
programming procedure at this point and request
values be entered for PRODUCT TYPE, VALVE
Prairie Pro Operator's Manual MY19 - REV 2
a en
NT R key must first
AL
TYP
TYPE, METER CAL, VALVE CAL, and RATE for this
2nd product. The console will then revert back to
STEP 8 if a 3rd product is not detected. If a 3rd
is detected the console will automatically request
the information be entered for this product before
continuing no to STEP 8 below.
For SCS 4400 console connected to a chemical
injection pump(s) see separate section on SCS 4400
chemical injection pump programming, in the "DCI"
chapter for further details.
STEP 8 - SPEED SENSOR TYPE
efore proceeding in this step first identify which
type of speed sensor the console is connected to.
Transmission output or Raven GPS:
1. Momentarily depress the [CE] key repeatedly to
toggle through the selection of "SPEED SENSOR
TYPES" until "SPEED SENSOR RADAR SP-2" is
displayed.
2. Depress the [ENTER] key to lock it in and the
console will now prompt for a "SPEED CAL"
number to be entered.
STEP 9 - SPEED CAL
efore a SP
CAL figure can be entered a
speed calibration value must first be ascertained.
The method for calculating a speed calibration figure
varies depending on the type of speed sensor the
console is connected to
For consoles connected to a transmission output:
Use an arbitrary [SPEED CAL] value of [200]
To enter this value:
1. Depress the [ENTER] key to display the "E" enter
symbol.
2. Key in the appropriate [SPEED CAL] number.
3. Depress the [ENTER] key again to lock it in.
4. The console will now prompt for a "BOOM CAL
1" number to be entered.
NOTE: This is an arbitrary value only and will require
correcting; using the following procedure, once
the remainder of the programming procedure is
completed.
To recalibrate a [SPEED CAL] value once initial
console programming is complete:
1. Accurately mark and measure 100 metres.
