for VENTA
DEAR OWNER,
In buying a KUHN machine you have chosen wisely. Into it have gone years of thought,
research and improvements. You will find, as have thousands of owners all over the world, that
you have the best that engineering skill and actual field testing can produce. You have
purchased a dependable machine, but only by proper care and operation can you expect to
receive the performance and long service built into it.
This manual contains all the necessary information for you to receive full efficiency from your
machine. The performance you get from this machine is largely dependant upon how well you
read and understand this manual and apply this knowledge. Please DO NOT ASSUME THAT
YOU KNOW HOW TO OPERATE AND MAINTAIN YOUR MACHINE before reading this
manual carefully. KEEP THIS MANUAL AVAILABLE FOR REFERENCE.
Your KUHN dealer will instruct you on the general operation of your machine. He is interested
that you get the best performance possible and will be glad to answer any special questions
that may arise regarding the operation of the KUHN machine.
Your KUHN dealer can offer a complete line of genuine KUHN service parts.
These parts are manufactured and carefully inspected in the same factory that builds the
machine to assure high quality and accurate fitting of any necessary replacements.
When ordering service parts it is important that you indicate the type of machine concerned
and its serial number.
For this reason please complete the model identification plate diagram below with the required
information. This will provide you with an easy reference for future service parts orders.
ABOUT IMPROVEMENTS
KUHN is continually striving to improve its products and, therefore, reserves the right to make
improvements or changes when it becomes practical to do so, without incurring any
obligations to make changes or additions to the equipment sold previously.

E Connections with a « MASTER » terminal (GPS mode)
The standard connection plug enables connecting the MDC control box to a terminal.
This link enables monitoring the application rate within the field (Precision Farming).
The GPS positioning and the corresponding application rate are transmitted by the
« master » terminal to the MDC control box.
Depending on the « master » terminal, the MDC control box will transmit in return
information on the work achieved, to the « master » terminal. Information on the use
of the « master » terminal is indicated in its operator’s manual.
E 1 Description
Following terminals, fitted with a standard RS232 plug, can be connected using a
cable 0 Modem Sub D9 (female/female) for connection to the MDC control box. The
wiring plan in the cable can be checked at point C2.

Prior to connecting the terminal and the MDC control box, select the connection
protocol in the « master » terminal.
This protocol is in one way the « language » which will enable communication between both control boxes. Refer to the « master » terminal operator’s manual to adjust this selection.

The MDC monitoring must be calibrated prior to the connection with the « master »
terminal, see points D1 to D7 in this manual.
The MDC control box keys are secured and are therefore inaccessible when working
in GPS mode.
If the connection is properly made between both control boxes,
the display shows the symbol opposite. Furthermore the LED
light flashes on the control box.
When switching off the « master » terminal, removing the connection cable or if there is a connection breakdown between
the 2 control boxes, the MDC control box screen displays the
symbol opposite after 10 seconds. The LED light is off.
The LED light is on without flashing if the « master » terminal modifies the application
rate and the motor adjusts the opening.
