  • Page 4: Base Kit

    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.
  • Page 5: Flow-And/Or Pressure-Based Plumbing

    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.

  • Page 9: Set No. Of Nozzles Per Section

    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.
  • Page 10: Pressure-Based Setup

    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.
  • Page 11: Manually Adjust The Pressure Sensor Gain Factor

    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.
  • Page 12: Adjust Nozzle Flow Rate And Reference Pressure

    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.
  • Page 14: Set No. Of Sensed Nozzles

    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.
  • Page 15: Minimum Pulse Width

    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.
  • Page 16: Speed Sensor Setup

    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.
  • Page 17: Number Of Sensor Magnets

    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.
  • Page 18: Example Calculation 1

    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"...
