Overview
This Manual
This manual explains the everyday use of the instrument to the
operator, including regular calibration e.g. changing the spread width
setting.
Application
The head unit is ruggedly designed for maximum reliability in harsh
environments, and is rated to IP67 (effectively waterproof). The
instrument has a 4-digit back-lit LCD display with 6 display channels for
different work measurement functions.
In the normal operating mode the following functions can be selected,
•
Forward Speed (km /hr)
•
Area Worked* (hectares)
•
Work Rate (hectares /hr)
•
Application Rate **
•
Spinner Speed (RPM)
•
Hopper Contents (kg or tonnes) – Theoretical or Sensed
*There are two memory registers to record area worked. The area is
accumulated to whichever total is selected on the display – ‘Total 1’ or
‘Total 2’.
The head unit is switched on/off by the switch on the back of the
instrument.
Area totals (and all calibration data) are automatically stored in memory
when the instrument is powered off.
**Application rate is displayed as a theoretical reference that is used to
monitor the hopper contents only.

RDS WIZARD MONITORING SYSTEM
Calibration
The instrument must be initially calibrated to suit the implement being
controlled. The forward speed factor (distance in metres covered per
revolution of wheel drive shaft or wheel hub) is pre-programmed at
installation.
In normal monitor use the spread width setting must be changed each
time a new product is spread.
An application rate derived for the Marshall Multispread Application
Rate charts can be entered. This value will be used by the head unit to
determine the low hopper level alarm when the hopper contents alarm
is set to theoretical.

2.1
Work Status Indicator
The indicator is used to indicate the channel to which the information
on the display relates. It also shows the working status of the spreader.
The cursor flashes when the spreader is out of work
(e.g on the headland)and the area accumulation stops.
The cursor is on continuously when the spreader is in work and
and area accumulation takes place.
Area Accumulation begins when a forward speed signal is sensed
i.e. the wheel drive is engaged. When the wheel drive is
disengaged area accumulation will be stopped.
2.2

The application rate can be shown in kg/ha or tonnes/hectare.

Forward Speed Display
The forward speed is displayed in km/hr.
3.1 Changing the Forward Speed Factor
If the operator finds a discrepancy between the Wizard forward speed
display and the tractor speedometer the forward speed factor must be
altered.
To alter forward speed factor:

holding the

4. When the correct figure is entered release the
key.
The forward speed factor has been changed.
NOTES:
To determine the correct wheel factor, measure the diameter of the
jockey tyre and then multiply by 3.141.
Then multiply this value by 2. (The RDS monitor forward speed factor
is calculated from the distance travelled per 2 magnet pulses)
Alternatively you can adjust the existing value by a percentage,
provided you know what percentage the wheel factor is out by.

Area Display
The area in hectares is derived from the forward speed and the programmed
implement width, and is accumulated to whichever total is selected on the
display – Total 1 or Total 2. The two separate area totals can be independently
reset to zero.
The area will stop accumulating when the wheel drive is disengaged. The
channel indicator will flash when area accumulation is overridden and will be
on permanently when area is being recorded.

Work Rate Display
The work rate is displayed in ha/hr. It is an instantaneous rate which is recalculated every 3 seconds from the working width set and the current forward
speed.

Application Rate
This channel is simply programmed with the application rate that you
intend applying fertiliser at, so that the instrument can calculate and
display hopper contents correctly.
Application Rate Settings can be found in the Marshall Multispread
handbook supplied with the spreader.

RPM Display
This channel will normally display the PTO speed or the spinner speed, but
can be another rotating shaft depending on your particular application.
7.1
RPM Alarm
The RPM channel has an under-speed alarm.
Default setting:
Low Speed Alarm – 600 RPM
The RPM alarm does not function when the forward speed is less than
2km/hr.
If the RPM falls below the programmed threshold, the display will default
to this channel and flash the actual RPM and the instrument will beep 5
times.
You can temporarily ignore the low speed alarm by selecting another
channel; however the instrument beeps and return to this display after
30 seconds. This will occur until the RPM increases above the
threshold.
NOTE : OPTIMUM SPINNER SPEED – 700-900 RPM.

Hopper Contents Display
This channel gives either a simple low level alarm or displays the
hopper contents, depending on how the system is configured.
8.1
Low Level Alarm (using optional hopper sensor)
If the hopper is fitted with a level sensor, when you select this channel
it will briefly display “1” to indicate that the alarm is enabled
NOTE:
This is the default setting. If “0” is displayed then the alarm is
disabled.
When the hopper contents fall below the sensor, the display will default
to this channel and flash “Alar”, and the instrument will beep 5 times.
You can temporarily ignore the alarm by selecting another channel,
however the instrument beeps and returns to this display after 30
seconds.
The hopper level alarm does not function when the forward speed is
less than 2km/hr.
8.2
Weight displayed (Qty left in Hopper/Qty Dispensed)
The system is initially installed in volumetric weighing mode.
The system calculates the theoretical quantity in the hopper, displaying
either the total weight dispensed or the quantity remaining in the
hopper, depending on how the instrument is configured in the
calibration mode.
If kg units are selected, the units are kgs up to “9999” thereafter the
decimal point indicating the readout is in tonnes (to the nearest 10kg)
e.g. 10.10 tonnes.
8.3
The “Quantity in Hopper Display”
If the Hopper Maximum Quantity is set to a value above zero in the
calibration mode (refer to the Installation/Calibration Manual to set
this), the display will count down from the maximum figure, showing the
quantity of product remaining in the hopper.
When the calculated weight reaches the pre-programmed hopper
alarm-weight, the instrument will alarm in the same manner as
described above.

8.3.3 Adjusting the “Hopper Maximum quantity” figure
The meaningfulness of the display is reliant on the Hopper Maximum
Quantity being correctly programmed for the actual quantity of product
in the hopper at the start.

hopper)

counting down from the figure that has been entered above.
8.4
Quantity Dispensed Display
If the Hopper Maximum Quantity is set to zero in the calibration mode,
the alarm function is disabled and the display will count up from zero,
indicating the quantity of product dispensed.
8.4.1 Resetting the Quantity Dispensed Display to Zero
You can reset to zero, e.g. if logging individual hopper loads, field totals,
daily totals etc. Please note however, that aside from this channel total
there is no independent “grand total” that stays in the instrument’s
memory.
