SPRAYMASTER 200 The Spraymaster 200 can be retrofitted to almost any make or model of sprayer - self-propelled, trailed or demountable, and configured for either flow-based or pressure-based regulation. It is therefore, supplied as a modular system comprising a Base Kit, plus individual kits specified as required for the particular installation, e.g.
SPRAYMASTER 200 Flow-and/or Pressure-based Plumbing Figure 2 illustrates the general plumbing arrangement for the RDS components. [1] General installation instructions are included in the individual kits. Please refer to these as required. Any additional instructions specific to a Spraymaster installation are given in section 1.3.
SPRAYMASTER 200 Terminator Figure 3 Additional information not covered by the individual kit instructions The "Terminator" is the central junction box to which all other components are connected, including the power supply. NOTE: The Terminator is not sealed. It must be located where it will be protected from...
SPRAYMASTER 200 Reverse Polarity and Power LED The head unit has reverse polarity protection and therefore will not be damaged if you inadvertently have the power supply connections reversed. The LED on the Terminator PCB will not light when the 0V and +V connections are reversed.
SPRAYMASTER 200 Calibration Boom/Cutout Switch Setup Boom configuration enables the instrument to automatically recognize the correct number of nozzles in use at any moment in time. 2.1.1 Enable Single Boom Configuration (Standard) Cal Mode 3 ( + Power-up ) - Channel 3: Setting = '[FuLL]', '1''...
SPRAYMASTER 200 2.1.4 Set No. of Nozzles per Section Cal Mode 1 ( + Power-up ) - Channel 6: Default = '0' For single section sprayers fitted with a simple cutout switch, the number displayed is the total no. of nozzles for the boom.
SPRAYMASTER 200 (iii) Pressure and flow sensor input. If the pressure sensor gain is set >0, and one or more flow sensor factors are set >0, then you can select either 'PrESS' or 'turb' using the '+' and '-' keys.
SPRAYMASTER 200 Adjust the displayed pressure using the ‘+/-’ buttons to make it agree with the external gauge reading. 10. Press the button, the display will show ‘donE’ briefly, followed by ‘GAIN’. 11. The ‘GAIN’ calibration factor can be viewed by pressing and holding button.
SPRAYMASTER 200 2.3.3 Adjust Nozzle Flow Rate and Reference Pressure Cal Mode 1 ( + Power-up ) - Channel 4: Default - see table 1). This channel allows you to set the default nozzle and set the correct nozzle flow rate for a given reference pressure following a jug test.
SPRAYMASTER 200 Flow-based Setup 2.4.1 Enable / Adjust Flow Sensor Cal Factor Cal Mode 3 ( + Power-up ) - Channel 4: Default - All factors zero). To enable flow-based regulation, at least one cal factor must be set > 0.
SPRAYMASTER 200 2.4.3 Set No. of Sensed Nozzles Cal Mode 3 ( + Power-up ) - Channel 5: Default = This only needs to be set if an ACI and a flow sensor is installed. Normally the sensed flow is for the full boom width, but in some installations for practical reasons, it may only be the flow to a particular boom section.
SPRAYMASTER 200 2.5.2 Minimum Pulse Width Cal Mode 2 ( + Power-up ) - Channel 3 This sets the minimum pulse length (milliseconds x 4) driving the flow control valve. The pulses becomes shorter as the application rate nears the target rate.
SPRAYMASTER 200 Speed Sensor Setup Cal Mode 1 ( + Power-up ) - Channel 1 In order to display the correct speed and accumulate distance correctly, the instrument must be programmed with the correct Speed Sensor Factor (SSF). This is the distance travelled between pulses received from the sensor.
Carry out this test whenever soil conditions or wheel sizes change. (iv) If an RDS Radar sensor is installed, the Speed Sensor Factor is 0.008 m (or 0.312 inches). If the calibration factor works out at over 2.000 m (78.78 inches), consider fitting additional magnets.
SPRAYMASTER 200 Example Calculation 1 The tractor is fitted with a single-magnet propshaft sensor. The measured distance for 10 rotations of the propshaft is 17'-6". Convert the distance to inches :- (17' x 12")+6" = 210" Divide by 10 (magnet pulses) to give the calibration factor:- 210" / 10 = 21"...
SPRAYMASTER 200 Other Settings 2.7.1 Set Step % in Automatic Mode Cal Mode 2 ( + Power-up ) - Channel 6 In manual mode the '+' and '-' keys drive the valve directly. In automatic mode the target application rate is adjusted in % steps.
