Operating and mounting instruction:
SLUG-Security
Slug security, universal seeder for seeding small seeds and slug pellets.
Seeder unit: stainless steel.The seed output is carried out by a serrated seed roll. With the
speed of the seed roll you can adjust the output amount.
Step 1 is for the smallest amount output and the highest is
on step 10. From the hopper the seed gets out to the
spreader plate through the seed rolls and 1 tube. The
spreader plate distributes the seed semicircular.
According to the speed oft he spreader plate the spreader
width varies. Step 1 is for a small spreader width and step
10 for the most possible width. The spreader width
depends on the character of the seed. With heavy seed
(f.e.: slug pellets to 24 m; mustard, peas, rape) you can
reach a higher spreader width than with small and light
seed (f.e.: grass seed to 6-7m).
Take attention when adjusting the bottom flap (hand gear
lateral to seed unit). For big seed a small slot has to be
that the seed doesn´t crumble. For small seed put the bottom flap as near as possible to the
seed roll (otherwise you get amount differences).
The hopper is closed with a sealed cap. The seal has to be proofed periodical with seal
silicone.
For moving the outlet tube loose the 2 bolts. Now you can adjust the spreader radius exactly.
Every corn has its own flying character. So it is profitable to have the chance of adjusting the

spreader radius. Additionally you can adjust it also with
the throw blades on the spreader plate. If you turn the
throw blades clockwise (seen from above) the seed
(seen in driving direction by mounting on a sub sequent
basic unit) is taken more to the left. Adjusting against
clockwise turn effects the opposite.
Calibration:
To get the seed in the tank remove the bolt near the carrier profile. Then you can put the outlet
tube to one side and catch the seed in the tank.
f.e.: working width 1,5 m x driving speed 8 km/h x output amount/ha 20 kg
60 min.
1,5 x 8 = 1,2 ha/h x 20 kg/ha = 24 kg/h : 60 min. = 0,4 kg/min.
Results an amount of 0,4 kg/min. which has to be collected in a tank.
Safety regulation:
During working on the machine make sure that the machine is turned off and the
current supply is broken. The motor is very powerful and doesn’t stop because of
fingers, hair or loose cloth. Keep safe clearance. Before starting check if there are no
persons, animals or easy damaging things in the danger area. Keep children away from
the machine.

With the delivered control unit you can adjust the
speed stepless.
1 = lowest rotation speed
10 = highest rotation speed
Direction of seed roll rotation:
Take attention on the direction of seed roll rotation.Because of false direction it rolls up the
thread in the seed roll.
•IMPORTANT:
•Clean carefully and inject the machine after every season.
•For filling mount an antislip and an overturn safe climb.

Advanced settings (new program)
There are three settings:
Two regulator parameters that can be changed (PI-regulator) and the polarity of the area-
switch.
Default values for the parameters are:
Parameter 1: 250 (Gain, P-factor) *
Parameter 2: 50 (Integration, I-factor)**
Parameter 3: 0 (Polarity area-switch, 0 or 1)***
Changing the parameters are done by holding both SET button and RESET button down for 2
seconds when the kg/ha value is displayed.
The RESET button must be released before the SET button for activating the changing
procedure.
The first regulator parameter is displayed and the display is flashing. Press UP or DOWN for

By pressing SET the value is accepted and saved and the second regulator parameter is
displayed. Press UP or DOWN for changing this value.
Press SET and the value is accepted and saved and the third parameter is displayed to change
the polarity of the area-switch. Press UP or DOWN for changing this value.
By pressing SET again this value is accepted and saved, and the display will go back for
displaying the kg/ha value.
Pressing RESET will abort the current settings if it is not accepted with SET.
* If parameter 1 is set to high the seed output starts to oscillate. If oscillation occurs then
reduce parameter 1.
** If parameter 2 is set to high the seeder output can be unstable. If the seeder output is
unstable try to reduce parameter 2. If the amount from the seeder output is not correct
according to driven area try to increase parameter 2.
*** If parameter 3 is set to 0 the machine is active when the area-switch input signal is high.
When parameter 3 is set to 1 the machine is active when the area-switch input signal is low.
