User interface
Display appearing after switching on the control system k-tronic.

Turning knob
The control system k-tronic disposes of 3 turning knobs in the lower area. The turning knobs have no
internal/mechanical stop, they can be rotated continuously.
In addition, the turning knobs feature a push-button function. To actuate this button, the turning knob must be pressed
in the direction of the rotation axis.
The turning knobs have partly different functions within the different menu options. During turning the turning knob,
the value of the setup screens changes at the last digit. At many setup screens, the values can be modified with the
turning knob pressed; the setting value changes by factor 100 per detent.
At particular setup screens, the push-button of the turning knob triggers actions.

Button 1 to button 6
The control system k-tronic has 6 buttons.
The buttons have partly different functions within the different menu options. If a
button with a small symbol is displayed (e.g. button ), the button closest to the displayed symbol is
meant.
In certain cases, a different button must be pressed for a function (e.g. right and left shift key).

Button ON
The button ON at the control system k-tronic switches on and off the supply voltage of the spreader.

When switching on by means of the ON button, the spreader always starts at level 1 with operating mode .
The spreader starts also at level 1 even if the control system has been switched off at level 2.
When switching off by means of the ON button, all drive units will be stopped and all connected consumers
will be switched off.

Menu
A menu consists of one or several menu lines. A further menu or a setup screen can be attached to a menu line.
Depending on the equipment of the spreader, individual menus may feature a lower number of menu items as
described here.
Go to a subjacent menu or setup screen by means of button 6 .

Leave the menu or screen by means of button 4.

Choose menu line

Skip from one menu line to the next by turning the left turning knob . The menu line
highlighted in dark color is selected. By turning the turning knob clockwise, the menu line below will be selected; by
turning anti-clockwise, the menu line above will be selected. If a menu consists of more than 5 menu points, the whole
menu will be built up on several pages. It is possible to browse within the menu in blocks of a maximum of 5 pages. To
control where you are currently navigating, a small rectangle is shown on the right side that moves up or down
depending on the menu line.

Soft switch
There are menu lines offering a 0/1 possibility to select. In such cases, the respective menu line is equipped with a so-
called soft switch. The setting is limited to “ON” ( ) or “OFF” ( ). The current switching status of the soft
switch is displayed in the respective menu line for review. With the menu line selected, the alternative switching
status is displayed at button 5.

Setup screen
A setup screen may be attached to the menu line. A setup screen is split into three columns, whereby values must not
be stored in all three columns. Always use the turning knob below to change values within a column. The modified
values of the setup screens are adopted and stored immediately.
With a menu line selected, go to the setup screen by means of button 6 .
Use button 4 to leave the setup screen.

If a large value range can be set in a column of the setup screen, the value may be changed by
factor 100 per detent by turning the pressed turning knob.

Speed signal
In order to guarantee correct operation of the spreader with path dependence, the speed signal of the spreader must
be adjusted to the respective vehicle. You have three different entry possibilities:
- Teach-in
- manual entry
- via distance

Teach-in
Teach-in is a simple method to adjust the speed signal to the respective vehicle. Drive the vehicle with one of the two
preset speeds (15 km/h or 30 km/h) and press the turning knob with the respective indication “Teach-in 15 km/h “ or
“Teach-in 30 km/h”. The value for the speed signal will be determined and saved for displaying the speed at the
control system k-tronic.
For controlling purposes, the current speed is displayed in the upper right corner. The display is calculated via the
value which is stored in the control system for impulses per driven meters.

The impulses per driven meter currently stored in the control system are displayed in the middle column. In case of
minor deviations between the display at the control system k-tronic and the speedometer, the value for the impulses
per driven meter can be corrected by means of the middle turning knob. When exiting the setup screen by means of
button 4
, the last value displayed is maintained for the calculation of the speed display and thus for the calculation of
path dependence.
In case of minor deviations between the display at the control system k-tronic and the speedometer, you can of course
press the respective turning knob anew as soon as the indicated speed of 15 km/h or 30 km/h has been reached. This
can be repeated until the result is satisfactory. When exiting the setup screen, the last determined value for the speed
signal is saved and will be used for the operation of the spreader in case of path-dependence.

Manual entry (speed signal)

In many cases, the value for the speed signal is indicated in the instruction manual of the vehicle on which the
spreader is mounted. If the value for the speed signal of your carrier vehicle is known, you can directly set this value
in the setup screen “manual entry”.

Setting range: 0.50 to 650.00 impulses/meter

If your vehicle supplies a higher value than 650 impulses per meter, please interpose our speed signal divider. By
means of this signal divider, the speed signal from the vehicle is divided down by the factor 10 and fed to the control
system k-tronic. Thus, values up to 6500.0 impulses per driven meter may be recorded.
English

 14 Control system k-tronic

Via distance
You can also determine the speed signal for the spreader via an exactly calculated distance. You drive up to the starting
point of the measuring distance, press the start button, cover the measuring distance directly without stopping and press
the stop button at the end. All impulses between pressing the start and stop button are counted and calculated together
with the entered distance.

It is important to cover the distance directly, each change of direction leads to a wrong measuring
result.

If there is a deviation between the speed signal at the vehicle and the display at the control system
k-tronic, this may have different causes:
- change of direction during driving the measuring distance
- start or end point not exactly reached
- worn tyres of vehicle
- driving with snow chains etc.

Sensor adjustment
The sensors of the individual drives are set at the manufacturer's works. If, contrary to expectations, a sensor does
not function, the function of the individual sensors can be controlled at this setup screen. If a defective sensor has
been replaced, the new sensor is set to the correct distance with respect to the sensor disc or the motor shaft by
means of this setup screen.

To move the respective drive, the hydraulic system has to be switched on; then, you press the middle turning knob.
At the lower right corner, 2 small numbers appear.
The upper number indicates the current distance from the sensor to the punched disc or motor disc. If the individual
values are smaller than 70, this can lead to a failure during teach-in of the regulator adjustment. In case of values
above 210, the sensor may be destroyed.
The lower number shows the identified impulses. If this number does not change, the sensor may be too far away,
connected incorrectly, the sensor line may be interrupted or the sensor may be defective.

It is important to carry out the setting of the spreading disc sensors and the brine pump with greatest caution, because it
is not possible to see the distance between sensor and the toothed shaft. It is recommended to turn in the sensor only in
small steps and check at regular intervals in between. If the sensor is advanced too far at the beginning, it may be
destroyed by the turning shaft.

 16 Control system k-tronic

Regulator adjustment
The control system k-tronic determines own regulator parameters for each hydraulic drive. These regulator parameters
are necessary so that the drive units reach the correct speeds after a spreading pause or a change of settings.

The basic setting of the individual regulators must be carried out at each spreader with the corresponding
hydraulic oil supply.

Parameters
At the control system k-tronic, one set of parameters is part of each hydraulic drive. These 2 parameters are necessary
for the control behavior of the relevant drives. These parameters are determined by means of numerous tests and must
usually not be corrected. The damping stands for the reaction time of the regulation and the ramp stands for the
amount of change.

If a drive should overshoot or undershoot in case other values are regulated, it is wrong to increase
damping in order to faster reach a value. Overshoot or undershoot may only be avoided by reducing
the values.

Teach-in
To reach a correct working result of the spreader, a teach-in of the individual hydraulic motors of the drives is
necessary during first assembly of the spreading unit. This is done via teach-in.

Observe the following rules for teach-in:

- The sensors must be set exactly

- The hydraulic unit must supply a sufficient quantity of oil. Set the vehicle speed to the upper limit of the
green area.

- The speed must be constant during the whole teach-in procedure.

Tip button 1 to start the teach-in. The drive starts to rotate slowly and is getting faster until the
English

maximum speed has been reached. This procedure is run through 2 times. In case of danger, it can
be stopped by pressing button 4.

Subject to modifications
 Details menu 17
www.kugelmann.com
The progress of teach-in is displayed at the appearing bar. At the end of the teach-in, values are
shown and the result whether the attempt was successful or not.

If the teach-in has failed, it has to be determined by means of the displayed values why the error has occurred.

The determined values for 0 to 10 must be in ascending order. If one value is higher than the value that follows,
the teach-in has to be carried out once again because there may be some air bubbles left in the oil circuit.

If several values are out of sequence, the sensor of the respective drive should be checked once again. During sensor
adjustment, no single value of the smaller number must be below 70!

If a value above 1900 exists for one parameter, all values are rejected although a uniform increase of values would be
present. Maybe the oil supply has collapsed or the speed was not constant until the end.

If 0 is present at value “0”, this may mean that the drive rotates without external intervention. Check whether the
handwheels at the hydraulic block are closed, start teach-in again.

Characteristic curve
Caution! In this setup screen, wrong operation may cause the greatest damage. Incorrect operation
may lead to maladjustment of the characteristic curves, this means that the drives may turn very
slowly or not at all. Incorrect operation may also lead to the setting of a characteristic curve which is
not “OK”.

In this setup screen, the desired parameter is set at the left side: 0 - 10

In the middle, the numerical value for the parameter set at the left side is displayed: 0.00 to 20.00 W

At the right column, the determined frequency for this drive is displayed: 0.00 to 300.00 Hz

Error delay
As a continuing oil flow can not be guaranteed at some oil supply systems, e.g. in case of PTO pumps, the individual
errors can be delayed in such cases. For example, the delay of speed monitoring (sensor defective) can be delayed for
the period of one switching operation.
Delayable:
English

- Oversupply (0 - 25.0 seconds)

- Sensor defective (0 - 25.0 seconds)
- Undersupply (0 - 25.0 seconds)

Adjustment of spreading image

Only for spreaders with “Electrical adjustment of spreading pattern”.

Increased danger of contusions. During the adjustment of the spreading pattern, do not reach into
the displacement range of the spreading disc suspension.

Setting ranges of the spreading image values: from 0 to 255

MINIMUM: from 0 to “working range - LEFT”
LEFT: from “mechanical limits - MINIMUM” to “Working range - CENTER”
CENTER: from “working range - LEFT” to “Working range - RIGHT”
RIGHT: from “Working range - CENTER” to “mechanical limits - MAXIMUM”
MAXIMUM: from “working range - RIGHT” to 255

Current limit
The motor current is monitored to recognize blocking of the servo motor. As the motors may have different sizes, the
current limit for the respective motor size has to be set here.
Example: Linak Type 121P00 -> 1.8 ampere or,
Linak Type M301P1 -> 4.0 ampere

Mechanical limits
The mechanical limits are determined during first commissioning of the spreader and indicate the maximum
displacement travel of the electrical adjustment of the spreading pattern. These settings are made at the manufacturer's
works. If the motor should be replaced, these mechanical limits have to be determined again.

If a new value is entered in the setup screen for min. or max., this new value will be reached immediately. For
controlling purposes, a small number appears at the center of the display showing where the servo motor is located at
the moment.

If, in a column, the value cannot be modified in a certain direction, this is limited by the setting ranges mentioned
above.

If the motor should block, an error tone will sound and the control number at the center does not change anymore. If the
error tone sounds when setting the minimum limit, the value for minimal must be set slightly higher than the displayed
English

control number. Example: If the control number remains at 23, the value for MIN. is set to 25.
When setting the maximum limit, the value for MAX. must be set slightly lower than the reached control number.

 Details menu 19
www.kugelmann.com
In case of danger, the movement of the servo motor may be stopped immediately by pushing a
button or a turning knob.

Working range
The setup screen “Spreading pattern control values” is attached to the menu point “Working range”. The set values
may be retrieved by the pressed down middle turning knob in the user interface.

The value LEFT for the working range indicates the setting the servo motor takes for the left spreading image
position. Always indicated in the direction of travel.

The value RIGHT for the working range indicates the setting the servo motor takes for the right spreading image
position.

The value CENTER for the working range indicates the setting the servo motor takes for the middle spreading image
position.

The positions in between are calculated by means of the 2 enclosed values.

If the value of working range LEFT can no longer be reduced although the mechanical system has not yet reached its
limits, this is due to the fact that at the mechanical limit MINIMUM and the column LEFT the same number is
indicated.
In this case, you can adjust the value at the mechanical limit LEFT.

The same applies for the setting value at the working range RIGHT.
The mutual limitations are visible at the page at the side.

Button 1 - Spreader START

A short spreading attempt may be started for a quick check of the set values. For this spreading attempt, the spreading
data are used which were set when entering the user menu at the user interface. As the adjustment of the spreading
pattern is mostly executed at vehicle standstill, it makes sense to switch to manual mode/simulation speed at the user
interface.

Movement during emptying

If this option is activated, the servo motor drives to MAX. when entering the mask “Emptying”. This option is
mainly used for three-point spreaders as the screw units may clog during emptying.

Spreading materials
In this menu, the individual spreading materials are approved for the user. The following spreading materials can be
selected:
- Salt
- Refined salt
- Grit
- Sawdust
- Special 1
- Special 2

The spreading material brine does only figure in the list if the spreader is equipped with the option brine equipment.

If the line with the corresponding spreading material is selected, it is possible to change between active and
not active by means of button 5.
The spreading materials provided with a at the corresponding menu line are listed at spreading material
selection at the user interface.

Spreading materials which are set at the user levels can not be deactivated here. It is not possible to deactivate the
last spreading material left on the list.
For „MAX“ or „X2“, level 2 must also be observed.

If a spreader should be converted from one single spreading material to another, proceed as
follows:
- The new spreading material must be approved in menu “Spreading material”.
- Replace the old spreading material at all levels of the user interface by the new one.
- Now, deactivate the old spreading material in menu “Spreading material".

Spreading material menu

For each spreading material, a sub-menu for settings is attached. You can branch into the attached menu as soon as
the respective spreading material is activated.
The values deposited here are decisive for the exact dosing during the spreading procedure.

The menus of the individual spreading materials contain the following points:

Imp/kg (manually)
English

The impulses per kilogram of the respective spreading material are indicated in this setup screen. Possibility to control
and correct the value here, if necessary. The value must be entered for each drive.

Setting range: from 2.00 to 450.00 impulses/kg

Subject to modifications
 Details menu 21
www.kugelmann.com
Imp/kg (teach-in)
The simplest way to determine the imp/kg is effected via teach-in.

The selected chamber must be filled with the respective spreading material. The screw channel must be filled before
measuring, so that the measuring result may not be distorted.

For the measuring, use a reservoir of an appropriate size (approx. 60 l). In case of a truck-mounted spreader, place
the reservoir below the corresponding screw outlet (with chute folded up). In case of a three-point spreader, place
the spreading disc as far back as possible.

Then, fill the reservoir via “teach”. Hold the left rotary encoder pressed. The drive starts running; the counted
impulses of the drive are shown for controlling purposes.

The fed weight is calculated by means of the impulses/kilogram currently set and displayed in the middle of the
setup screen. Fill the reservoir until the required impulses are counted.

As soon as the required number of impulses has been reached, determine the weight of the supplied spreading
material. Consider the net weight of the used reservoir. If the weighted weight deviates from the display value at the
control system, set the weighted weight by means of the middle turning knob.

To save the values, press the right turning knob “OK”. Only now the new indicated imp/kg are adopted for further
calculation.

If you exit the setup screen without pressing the right turning knob, the value will be rejected and the old imp/kg
remain valid.

When exiting the setup screen, the impulses counted up to this moment will be deleted.

Leakage brine pump at spreading material brine

To avoid formation of drops, a non-return valve is installed after the pump. To open this valve, the pump must
reach a certain speed. As this speed would be missing later during dosage, this speed must be set.

If all hoses are evacuated up to the non-return valve, the setting of the leakage speed can be started. Keep the button 1
(start of pump) pressed and set the speed with the middle turning knob in a way that a constant minimum brine flow is
visible at the nozzle. Values between 2.0 and 5.0 Hz are typical values.

Imp/kg teach-in with spreading material brine

Before you begin with the teach-in for brine, the leakage of the brine pump must be set (see above). No air must be

inside the hoses for brine dosage.

Before you begin measuring, place a reservoir (approx. 60 l) below the brine nozzle. Then, fill the reservoir via “teach”.
Hold the left rotary encoder pressed. The brine pump starts running;

 22 Control system k-tronic

the counted impulses of the pump are displayed for control purposes.

The supplied volume is calculated by means of the impulses/kilogram currently set and displayed in the
middle of the setup screen. Fill the reservoir until the required impulses are counted.

As soon as the required number of impulses has been reached, determine the weight of the supplied brine. Consider the
net weight of the used reservoir. If the brine weight deviates from the display value at the control system, set the
weighted value by means of the middle turning knob.

To save the values, press the right turning knob “OK”. Only now the new indicated imp/kg are adopted for further
calculation.

If you exit the setup screen without pressing the right turning knob, the value will be rejected and the old imp/kg
remain valid.

When exiting the setup screen, the impulses counted up to this moment will be deleted.

Output counter
The output counter is a counting mechanism at the user interface. If the output counter is approved at options, the values
set here are used for the calculation of the display. The operator can decide at the user menu whether the output

Additional level
The function of the level button (Button 5) at the user interface is determined at this menu point. The following
functions are possible.

- Button MAX
- Button X2
- Level 2

If a check mark exists in several lines, the function is assigned to the top line with check mark. If
none of the three points has a check mark at the end of the line, button 5 at the user interface is
without function and the settings of LEVEL1 are valid. This applies to the three values of the
following display increments: minimum setting value, step width and maximum setting value.

Sub-menu item: Button MAX

At the setup screen “Setting MAX value”, the specifications for the opening angle of the hydraulic valves are set. The
settable values from 1 to 10 correspond to the values in the characteristic curves of the respective drives.

If the spreader is operating, the valves are controlled by pressing the MAX button corresponding to the values set
here. The opening of valves is also carried out during vehicle standstill. The spreading width remains unchanged. At
“disc stop - pause” and vehicle standstill, the disc speed is set to the preset spreading width.

Spreading control

Function of spreading control

A contact microphone is installed at the spreading disc protection. If, during spreading, this contact microphone vibrates
due to the spreading material, the downstream electronics evaluates this and signalizes to the control system k-tronic
that spreading material leaves the spreading disc.

The spreading control does not recognize from which chamber the spreading material is spread.
The spreading control can not check whether one of the two spreading chambers is empty.

The spreading control can be activated at the options of the details menu.

Evaluation of spreading control at the k-tronic

First, the result of the evaluation electronics is displayed directly at the user interface in the upper area. Second, the
signal at the control system k-tronic will be evaluated further and adopted to the warning list as warning 4.

Setting of delay of electrical monitoring of spreading process

When starting the spreading operation, a certain time elapses until spreading material leaves the disc. In order to avoid
that a warning is emitted after each spreading start or each start-up of the vehicle, delay times can be entered for the
issue of warnings. ON stands for the time until a warning is issued if no spreading material puts the contact microphone
into vibration. OFF stands for the delay time between recognition of spreading material until the warning is cleared.

Setting of evaluation electronics

The spreading control must be set to the correct sensitivity via the potentiometer in the evaluation electronics. The
spreading device is operated by means of simulation speed with a spreading width and spreading density normal for
operation and the potentiometer will be turned until the evaluation electronics recognizes the spreading material. The
LED display on the circuit board of the evaluation electronics serves for monitoring.

Afterwards, carry out a check during a spreading pause whether the sensitivity of the contact microphone is set
English

correctly. The spreading material symbol at the user interface must be crossed out.

Protocol
At the control system k-tronic, you can record the spreading data during driving.

Switch on the protocol at “Options” - a check mark must be placed at the end of the line.

After activation of the protocol, the control system k-tronic must be switched OFF and ON again.

Currently, only the transmission protocol of the company Mobiwork Telematik GmbH, Rosenheimer Strasse 44,
83064 Raubling (www.mobiworx.de) is supported. Transmission protocols of other recording devices upon request.

The data cable of the recording device is connected at the back of the master of the control system k-tronic.

If an update is made at the control system k-tronic, the protocol has to be switched off for the
period of the update. Switch OFF and ON the control system after locking of protocol output.

Speed reporting
At the control system k-tronic, you can monitor the speed during the spreading operation.

For this purpose, activate the line with the entry “Speed reporting” in the options. Set the speed limit in the attached
setup screen. Values from 10 to 90 km/h can be set.

If the set speed is exceeded during spreading, a signal tone is emitted. In addition, a message in clear text will appear at
the user interface.

Standstill message
During the spreading operation, the control system k-tronic monitors the speed signal for incoming impulses of the
speed sensor. If these impulses are missing or if there are too few, a message can be issued.

For this purpose, approve the respective line in “Options”. Set the speed limit for the emission of the message at the
attached setup screen.

Setting range: from 0.1 to 4.0 km/h.

If the vehicle speed should fall below this speed limit during spreading, the standstill message will be issued. If
the speed signal should fail during driving, the standstill message appears, too.

The message is emitted in clear text at the user interface; in addition, a signal tone is issued. The message remains
active until the next speed signal will be received or if spreading is terminated.

Activation of input functions

You get to the menu line “Input functions” via options in the details menu. The possible entries 1 to 6 are
listed in the attached sub-menu “Input functions”.

The soft switch must be set in the respective menu line “Input .. Function”. If the input is activated via the soft
switch, it is possible to skip to the attached setup screen.

Assignment of function to activated input

A preset function can be selected from the list by means of the middle turning knob at the setup screen “Input 1..6
function”.

Functions of inputs
Only one of the functions described below may be assigned to each input.

Please make sure that the same function is not set for 2 inputs. This may lead to significant
disturbances at the control system.

The voltage of the input signals may not exceed the operating voltage of the k-tronic. The current
consumption of an input is max. 100 mA. With an operating voltage of 12 V, the current consumption
is approx. 40 mA, with an operating voltage of 24 V, it is approx. 80 mA. If these loads are too high for
the carrier vehicle, please consult us.

Function 0: Pause (momentary)

Function 1: Speed 0 km/h (latching)

If this function is assigned to one of the inputs, the speed of the determined speed signal is calculated with 0 km/h in
case of a signal connected to the positive supply voltage. The actual speed of the vehicle is not important.

If the spreading operation should be interrupted, for example during return movement, function 1 may assume
this task. A reversing signal from the carrier vehicle is required for this.

Function 2: Additional function (momentary)

The function of the right middle button (button 5) at the user level is reproduced. It is decisive which function is set
for the additional level.

If button 5 of the user level is the MAX button, this MAX operating mode is also reached by means of the input
assigned here in the master. The same conditions apply as with direct operation via the control system, the MAX
values are reached only during spreading and not during PAUSE.

If the X2 state is assigned to button 5 at the user level, the spreading quantity doubles if the button connected
here is pressed.

If button 5 is responsible for level change at the operator level, change the levels by means of the button connected
here.

Function 3: Switch on/off brine (momentary)

If the spreader is equipped with brine equipment, the external button (optional connection) switches on/off brine. The
evaluation of the button is assigned to the operator level 1 or 2 set at the display.

Automatic locking
If the same spreading material is set for both chambers, the spreading quantities are coupled in case of automatic
locking. That means that the sum of the spreading quantities is adjusted.

The setting values - i.e. minimum spreading density, display increments, maximum spreading density - now refer to
the sum of the spreading quantities and no longer to the respective chambers.

At spreaders with separate chambers, the spreading quantities are split according to the ratio.

Chamber partition wall

If the spreader is equipped with a partition wall within the chamber, the soft switch must be activated.
The ratio of the separated chambers is set in the sub-menu “Chamber ratio”. This influences the locking (see above) and
the setting of the spreading material.

With separated chambers, the spreading material can be set for each chamber separately. With the chambers not
separated, the spreading materials are coupled at the main display.

Double dosing
If the drives of the screws are coupled mechanically or hydraulically, double dosing must be deactivated.

If double dosing is switched off, the two screws are no longer controlled separately, but by a joint control loop.

With double dosing switched off, the appearance of the superordinate menu changes significantly. The function of the
respective menu points remains unchanged.
