AN INTRODUCTION TO PARALLEL SWATHING
Parallel swathing can be carried out in three different ways; driving around the
headland and parallel to a straight line or a curved line. Typically, work will start by
driving around the headland 2 or 3 times and thereafter “side to side” (as with
tramlines).
Whilst driving around the headland it is possible to create a reference line from
which the remainder of the field can be driven parallel to. This reference line is
created by marking 2 points, point A and point B. The shortest possible distance
between 2 points is a straight line and this straight line is the reference line that is
driven parallel to for straight guidance(not the headland).
The reference line can be created, as mentioned before, whilst working the
headland, but also at any other time whilst driving. Once the reference line is
marked, it is possible to drive parallel to this line anywhere in the field.

STRAIGHT GUIDANCE
Straight guidance is simply driving in a straight line parallel to the reference line
created with points A & B. Once the reference line has been created it is possible
to drive parallel to the left and/or the right of the line and before and/or after the
initial reference points (A & B), the following diagram illustrates this:
The solid line represents the reference line
created with points A & B.
The dashed line shows that parallel lines are
automatically created on the left- and right-
hand side plus in front of and behind the
reference line.
This means that parallel guidance is possible
outside the points A and B
CURVED GUIDANCE
Curved guidance is driving parallel to a curved line in a similar fashion to straight
guidance. Parallel guidance is possible to the left and/or right of the reference line
but not before or after the initial reference points. The following diagram illustrates
this:
The solid line represents the initial
reference line created with points A & B.
The dashed lines show that parallel lines
are automatically created in front of the
initial reference line.
The dashed lines also show that parallel
lines are not created in to the side of the
initial reference points
This means that curved guidance is not
possible outside of the points A and B
HEADLAND GUIDANCE
Headland guidance is driving parallel around the headland of the field. Once the
headland has been completed it is possible to drive to the left and/or to the right of
the initial bout. A reference line (A & B) for straight or curved guidance can be
created whilst in headland mode.
A detailed example of headland guidance can be seen on page 11.

OPERATION
OPERATING MENU OVERVIEW
GENERAL
Each menu item is described in the following:
Encoding all settings is necessary for correct operation, see ENCODE on
page 17.
NEW?
Select this if starting a new field. Previous fieldwork will be erased (not
encodements).
RESUME?
Select this to continue work in a previously worked field.
APPLY ON/OFF
This function is only displayed if “STATUS” = OFF under encode – see page 19.
If the system is not fitted with an “implement sensor” (see “FITTING THE
CENTERLINE” on page 24) then this function is used to, manually, tell the system
whether the implement is in work or not.
If the system is fitted with an “implement sensor” and “STATUS” = ON under
encode the system will automatically detect if the implement is in work or not.
HEADLAND/STRAIGHT/CURVE AB
Select whether the machine is driving around the headland or driving straight
(parallel to a reference line) – see “AN INTRODUCTION TO PARALLEL
SWATHING”) on page 8.

All straight guidance work hereafter will be parallel to the reference line. A new
reference line can be created at any time during work in the field by following this
(the above) procedure.
The reference line remains in the memory until either:
1. A new real-time guidance is started (using the "Continue?” function keeps
the reference line).
Or
2. A new reference line is created (only one reference line can be stored at a
time).

AREA
It is possible to measure and thereafter see, e.g. the size of the field, with this
function.
The field area is automatically calculated from the driven circumference (of, i.e. the
field).
If the field area has not been measured with the CenterLine before then select
whether the actual field boundary is on the RIGHT- or LEFT- hand side of the
implement after selecting the AREA function. The display shows that area is being
measured whilst driving.
The area measurement will automatically stop and close the boundary when the
implement is within 4.5 metres of the start position. The boundary can also be
closed manually by selecting “CLOSE”. When the boundary is closed, the field
size is calculated and the area is saved. The calculated area is displayed for 3
minutes and can be seen again by selecting the “SHOW” function under the AREA
menu.
The calculated area remains in the memory until either:
1. A new real-time guidance is started (using the “Continue?” function keeps
the calculated area).
Or
2. A new area measurement is started.
E-DIF
Using e-Dif is normally not necessary in area where correctional signals
from Egnos are available.
Only displayed if the system is fitted with a RX350P Egnos DGPS receiver
(no. 78-50108).
Calibration for the e-Dif receiver. Please see the description on page 22.

USING THE RETURN TO POINT FUNCTION
The “Return to point” function is used when a marked position in the field is to be
found again. This function is typically used when work in the field is stopped and
the point at which worked stopped is to be returned to.
The “Return to point” function is operated with the “Return to point” key (pos. 2,
see page 7).
When a certain position is to be marked simply press this key. The marked
position will remain in the memory until either:
1. A new real-time guidance is started (using the “Continue?” function keeps
the marked position).
Or
2. A previously marked position is returned to and the key is pressed again
(3rd.time).
When the marked position is to be found again simply press the key again. The
lightbar guidance lights will show the way to drive and the display will show the
distance (in metres) between the present position and the marked position.
Press the “Menu/Esc” key to exit the “Return to point” function when the previously
marked position has been found.

GENERAL
There are two shortcuts in the setup menus, NEXT and TO START.
Selecting the NEXT function will automatically page back to the main menu for the
sub menu. Therefore, if, i.e. the SYSTEM menu is active and the NEXT function
was selected then the menu will automatically “jump” back to SETUP.
If the TO START function is selected, regardless of what menu is active, then the
system will automatically “jump” to the real-time guidance menu (operation). This
function can, e.g. be used if a setting needs to be altered during operation and
then the guidance task is to be continued.
We recommend encoding the system settings first as these decide, amongst
other things, the units used for operation and the other settings (see page
20).
GUIDANCE
All vehicle and implement related settings are encoded here.
The following settings presuppose that UNITS (in the SYSTEM menu) has been
set to METRIC and that the LANGUAGE is set to ENGLISH:
WIDTH
Encode the distance between the tracks in steps of 10 cm (min = 1m, max =
100m).
This width is typically the working width of the implement. If the encoded width is
set slightly smaller than the actual working width of the implement then chances
for “misses” in the field is reduced. If the encoded width is slightly larger than the
actual width of the implement, then overlapping will be reduced.
AHEAD
Encode, in seconds, how far ahead the Centerline should look ahead (typically set
to 1.5 or 2 seconds).
The look ahead function takes the current speed, direction plus this look ahead
value and calculates where the vehicle will be in relation to the current track. The
value to be encoded depends greatly on the machine operator.
When set to 0 the system does not use this function.
ANTENNA
The DGPS antenna is typically fitted either in front or behind the implement (front
mounted implements). Encode whether the DGPS antenna is in front or behind the
implement plus the distance between the antenna and the implement.
DIRECTION: Select “BACK” if the implement is behind the DGPS antenna.
Select “FORWARD” if the implement is in front of the DGPS
antenna.
DISTANCE: The distance between the DGPS antenna and the implement is
encoded in steps of 10 centimetres (min. = 0m, max. = 300m).
Consider the “drop point” of the implement. If the implement used
is i.e. a fertiliser spreader then the product will hit the ground up to
40 metres behind the DGPS antenna.
HEIGHT: The height from the ground to the DGPS antenna is encoded in
steps of 10 cm (min. = 0m, max. = 10m).

C ENTER L INE O PERATOR & FITTING INSTRUCTIONS E NCODE
19
STATUS
If this setting is encoded to “ON”, then the CenterLine will receive a signal from the
implement telling whether the implement is in work or out of work (see page 24).
This is used for, amongst other things, area measurement and warnings for
previously worked area (see the following alarm description).
If “OFF” is selected (standard setting) then the CenterLine will not give a warning
for previously worked area regardless of whether the implement is in work or out of
work.
ALARM
If “ON” is selected under ALARM then the CenterLine will give a visual warning
when a previously worked area is approached or driven into. APPLIED is shown in
the display when previously worked area is driven in, e.g. the headland.
If “OFF” is selected then no warning will be given when driving in previously
worked areas.
GPS TYPE
If differential corrections are not available, setting this menu item to GPS will allow
work to continue without reference signals.
When the standard setting (DGPS) is used a warning will appear on the
CenterLine and work can not continue should the differential signal be lost.
Accuracy will be greatly reduced if work is carried out without DGPS signals.
We do not recommend changing this setting.
1HZ MESSAGE
If the DGPS receiver being used is not able to send data to the CenterLine at an
acceptable rate it is possible to allow the system to accept DGPS signals from
such a receiver.
When the standard setting (NO) is used a warning will appear on the CenterLine if
the DGPS signals are not being received fast enough.
Accuracy will be greatly reduced if work is carried out with slow DGPS
signals. We do not recommend changing this setting.
LIGHTBAR
Settings related to the lightbar are encoded in the LIGHTBAR menus. A
description of these settings follows:
SPACING
This distance expresses the distance each LED on the lightbar represents. The
spacing can be set from 10 cm to 300 cm in steps of 10 cm.

E NCODE C ENTER L INE O PERATOR & FITTING INSTRUCTIONS
20
MODE
If MODE is set to “VEHICLE” then the middle line on the lightbar represents the
position of the implement. Steer the machine so that the middle line of the lightbar
is moved to the moving light.
If MODE is set to “TRACK” then the middle line of the lightbar represents the track.
Steer the machine so that the moving light is moved to the middle of the lightbar.
TEXT 1 & TEXT 2
Select one of the following text messages (one for TEXT 1 plus one for TEXT 2) to
be displayed whilst working:
X-TRACK: Shows the distance between the required track and the actual
position of the machine.
SWATH #: Shows the actual track number.
SPEED: Shows the present forward speed as kilometres per hour.
AREA: Shows the measured area that has been worked (not to be
confused with the calculated area from the AREA function as
described on page 15).
COURSE: Displays the machine heading in degrees.
OFF: No information is displayed.
STEER BAR?
When the STEER BAR option = “Yes” then all lights will be lit from the centre to
the left or right indicator light, whereas if the STEER BAR option = “No” (standard
setting) then only the left or right indicator light will be lit.
SYSTEM
UNITS
