! Disturbance to/from any electronic services or products that do not confirm to the standards for CE marking,
! Missing or poor signal coverage or a succession hereof from external transmitters/receivers, used by the buyer,
! Functional faults, which apply to or from a PC-program or PCequipment, not delivered by the seller,
! Faults that may arise from the buyers negligence to react to warnings and fault messages from the product, or which can be traced to negligence and/or absent constant control of the work carried out in comparison to the planned job.
7.2 When implementing any new equipment the buyer must take great care and pay attention. Any doubts as to correct operation/use should result in contacting the sellers service department.
This manual may not be altered, copied or manipulated in any way. Unoriginal manuals can lead to operational faults damaging machines or crops as a consequence thereof.

Pressing these keys starts/stops the time and distance counters.
SECTION FUNCTION (POS. 2)
Key
+/- %
Description
Pressing this key reduces the effective working width in steps of
25% - ¼ of the encoded working width. The encoded working width is not altered.
Use this function for, i.e. short work.
MENU KEY (POS. 3)
Key
Menu
Description
The computer alternates between the operating screen and the main menu each time this key is pressed.
The key has a toggle function so if the operating screen is shown and the key is pressed the main menu will be displayed instead and visa versa.
If the key is pressed whilst, e.g. encoding, the operating screen will be displayed.
ARROW KEYS (POS. 4)

THE SELECTABLE OPERATION FUNCTIONS (POS. 10)
This operation function is user selectable. The selected function is changed by paging through the available functions with program keys 1 and 2 (pos. 8).
A description of the available functions can be seen on page 9.
AREA/SECTION (POS. 11)
The worked area since the last reset (see page 10), shown as ha.
The area counter is shown with 2 decimal until 99.99 ha.
Hereafter the area covered is shown with 1 decimal until 999.9 ha.
The area is displayed without decimal thereafter.
If the section function is used a value (75, 50 or 25) will be shown in the area symbol. This value shows how much of the encoded working width is used in percent.
IMPLEMENT SENSOR STATUS (POS. 12)
When the displayed lift arm is raised the implement sensor is active and area, time and distance are not measured.
When the displayed lift arm is lowered the implement sensor is not active and area, time and distance are measured.
The time and distance counters are only started and stopped by the implement
sensor if automatic registration has been selected (see page 6).
FORWARD SPEED (POS. 13)
The current forward speed shown in kph.

PTO speed:
The speed of the PTO axle shown as RPM (presupposes that a RPM sensor is fitted to the PTO shaft).
Distance:
The driven distance since the last reset (see page 10).
The measured distance is displayed in metres until 9999 m.
The distance is displayed as km thereafter (-99.99, -999.9, -9999).
”Km” is shown in the symbol instead of ”m” when the distance displayed changes to km.
The distance counter is started and stopped according the Auto/Man
Ha Left:
Area remaining.
If the size of the field has been encoded before start the area remaining can be seen (The field size must be encoded before start,
Stop watch:
Used to measure the time for a particular job.
Time measurement is started and stopped according the Auto/Man
Ha/hour:
Working efficiency.
How large an area is being worked per hour with the current working width and the present forward speed.

DATA/DELETE (TASK)
It is possible to have up to ten different trip counter sets (tasks) that can be started and stopped when, e.g. changing fields.
The task menu is selected from the main menu (press the MENU key).
Press hereafter the ARROW UP and ARROW DOWN keys to mark “Data/delete”.
Press the ENTER key.
When starting a new task all the counters are zeroed. If another task is selected and then the original task is selected again the counters will continue with the same values from when the task was stopped.
The tasks can be reset one by one.

The screen to the left is displayed when the “Data/delete” menu is selected.
A description of each individual counter follows:
Area (Ha):
The measured area since the start of the task or since the last reset. The area measured is the effective area, so only the area that has been worked is counted.
Distance (m):
Distance in metres (effective distance) since the start of the task or since the last reset. How the distance counter is started and stopped is dependant on the
Auto/Man function (see page 6).
Time:
The total time used since the start of the task or since the last reset. How the time counter is started and stopped is dependant on the Auto/Man function

ENCODE
HA LEFT
Encode the size of the field here before start.
WORKING WIDTH
Encode the working width in centimetres.
Make sure that overlapping is accounted for. If the working width is unknown, drive
5 runs and measure the distance between the first and the last run.
Divide the measured distance by 5.
IMPLEMENT SENSOR
The signal from the implement sensor tells the monitor whether area should be measured or not.
The time and distance counters are started and stopped with the area counter if
automatic start/stop has been selected as described on page 6.
If ISO 3-punkt is selected the implement signal is taken from the lift arms.
If PTO is selected the area counter is started when the PTO axle is turning and stopped when the PTO axle is not turning.
FORWARD SPEED SENSOR
Selection of the forward speed sensor plus the speed calibration figure can be encoded here.
It is also possible to automatically calibrate the forward speed sensor.
Key Description
Pressing this key (program key 1) selects Radar as the speed sensor (via the 7-pin DIN-ISO socket).
If the number of pulses per 100 m is known it can be encoded directly.
Pressing this key (program key 2) selects a wheel sensor fitted on the tractor as the speed sensor (via the 7-pin DIN-ISO socket).
If the number of pulses per 100 m is known it can be encoded
directly.

Press this key and drive the measured 100-metre stretch. Stop exactly at the stop mark.
The computer counts pulses received whilst driving.
Press the ENTER key and forward speed calibration is finished.
PTO SENSOR
Encode the number of pulses per revolution for the sensor fitted to the PTO axle.
If the signal from the DIN-ISO socket is used the standard number of pulses = 40.
WARNINGS
The following warnings can be encoded her.
The warnings are given visually (on the screen) and as an audible warning:
PTO WARNING
Warning ON/OFF plus the minimum and maximum RPM at which the warning is required.
FORWARD SPEED WARNING
Warning ON/OFF plus the minimum and maximum speed at which the warning is required.

Use test input if, e.g. a sensor fault is suspected.
Directly under each input description, to the right, is a counter that registers the number of time the input has been activated (the counter is reset automatically each time “Test input” is exited or by pressing the C key). On the left-hand side the actual status of the input is shown (Hi/Lo).
All of the different inputs can been seen by pressing the ARROW UP and ARROW
DOWN keys to page through the 3 screens.
The different input descriptions relate to the following:
Input Description
Wheel Speed signal from the speed sensor fitted on the tractor.
Radar
Lift
Speed signal from the radar fitted on the tractor.
Implement signal (area on/off) from the implement sensor fitted on the tractor (via the 7-pin DIN/ISO plug in the tractor).
RPM signal from the RPM sensor fitted to the PTO axle. PTO
