$GENERAL DESCRIPTION
1. Description
Control box KMS208 is used to monitor the passage of
seeds. It can control 8 rows at most.
If there is an anomaly in one row, no seeds detected for
3 seconds or declutching fault, a buzzer and visual alarm
are triggered
Declutching box KMD112 can only work when coupled
to a KMS208 or KMS412 control box.
It can be used to declutch up to 8 rows, no matter what
the row or the moment..

2. Description of the connection
The box is powered by the tractor's 3-pin plug (DIN 9680,
ISO 12369) or the battery power cable supplied.
Part no. 83233001
Number Colour of
cable
Function
2 - 15/30 Brown + 12 V
3 - 31 Blue Earth
1 - 82 - Not used
The power cable (83233001) must be
connected directly to the battery (clean lugs)
to guarantee that the boxes work properly.
For tractors equipped with a battery cut-out,
the power cable must be connected just
behind this.
The 25 amp fuse must be in position
For connection to the tractor's own socket,
make sure there is a fuse on the tractor side.

Connection plate on the machine
The connection plate allows uses to adapter the cell (1)
and declutch (2) connections quickly when changing the
machine configuration.
The numbers of the connectors on the connection plate
match the numbers on the boxes.
The two left-hand rows 1 are for the cells.
The two right-hand rows (2) match the declutching
mechanisms.
If the number of rows on the machine is changed :
- change the wiring for the rows on the connection
plate.
Example :
Removing row N° 4 on an 8-row machine for a new 7-row
seed drill machine configuration :
- disconnect row 4 from the panel
- wire rows 5, 6, 7 and 8 to positions 4, 5, 6, 7
The initial row 4 must stay disconnected from the panel.
When switching on, the KMS208 will detect 7 rows
(LEDs 1 to 7 on).
For a machine equipped with declutching mechanisms,
changing 2-pin connections on the connection plage
must follow the same logic.
Unwired rows must be connected with a plug (provided)
to prevent the electrical contacts from being damaged.

Putting into service
$PUTTING INTO SERVICE
1. Operation
Before you start
For sowing under very dusty conditions, if the KMS208
alarm sounds more and more often, the cells must be
cleaned more often.
Power on
Press the on/off button briefly to switch on the monitor.
- Test the alarm buzzer
A buzzer sounds for one second and the green power
indicator comes on.
A cleaning brush is supplied with the box:
clean it at least once a day to prevent the cells
from being clogged.
The on/off button does not switch the
KMD112 declutching box on and off.
To preserve the tractor battery, remember to
disconnect the boxes when the job is
finished..
On the KMD112, set the declutching levers to
a minimum low position to reduce
electromagnet consumption. Tractor
stopped.
