K-DUCER is the new class A intelligent transducerized assembly system from Kolver.
Thanks to a sophisticated control system, the electronic circuit communicates with KDS series
screwdriver equipped with integrated torque/angle transducer and allows to stop the screwdriver
instantly when reaching the preset torque or angle.
The AC 90÷260V - 50÷60Hz power supply is converted into 40VDC required by the KDS series
screwdrivers through a switching board.
IMPORTANT: K-DUCER is a highly accurate unit but it is critically important to select the correct
options to ensure that proper torque is being applied. Read the menu description carefully and in case
you are unsure please contact Kolver for support information.
INSTALLATION:
Installation of KDU unit:
KDU control unit is supplied with a bracket.

Vers. 291020 4
On the back panel, there are four female threaded pivots 8 mm depth to be used to fix the bracket. KDU unit
is supplied with four M4x8 screws to help the plate to be fixed to the unit or to any other Kolver supports.
It is also available both a table stand (code 010400) and a vertically and horizontally adjustable bracket
(code 010401).
Installation of KDS screwdriver:
The KDS screwdrivers series require a 2.5m male/female cable (code 250064) or 5m (code 250564). Or
cables with strain relief (2.5m 250064/H and 5 m 250564/H).
To connect the cable to the unit, insert the male connector into the appropriate TOOL connector on
the bottom of the unit, taking care to respect the alignment tabs. Push the connector into its position
and turn clockwise the OPEN/CLOSE nut. Referring to the screwdriver, use the female side of the

Vers. 291020 5
cable and perform the same operations. To disconnect the connectors, apply a light pressure of the
cable connector towards the fixed connector and turn counterclockwise the nut.
Turn the unit on through the on/off switch on the lower panel. The unit will carry a general system check
and the words “NO SCREWDRIVER CONNECTED” will appear if no screwdriver is connected.

NB: It’s possible to enter the menu even without any screwdriver connected.
1- To enter the menu
Instead if the screwdriver is connected, it will be recognized by the unit and the "CONNECTED
SCREWDRIVER" screen will appear for a few seconds, also showing the model and serial
number.
NB. All parameters read during the recognition of the screwdriver can also be displayed in the
SETTING menu.
If the parameters set in the K-DUCER unit are outside of the range of the screwdriver, the
following screen will appear:

At this point select a different program by clicking on the "Access to the menu" button or modify
the parameter out of range.
The error messages can be the following:
TorqueTargOverMax
Target torque higher than the allowed limit for the screwdriver.
SpeedTargOverMax
Target speed higher than the limit allowed for the screwdriver.
SpeedTargUnderMin Target speed less than the limit allowed for the screwdriver (50
RPM).
DownshiftTorqueOverTarg
The
fast phase torque setting is higher than the final target torque.
DownshiftSpeedOverMax The speed of the slow phase of this program is higher than the
maximum allowed by the screwdr
iver.
DownshiftSpeedUnderMin The speed of the slow phase of this program is less than the
minimum allowed by the screwdriver (50 RPM).
TorqueMaxOverMaxLim In angle control: the maximum torque set in the program is above
the limit of the screwdriver.
In torque control: the maximum torque set in the program is higher
than 20Nm.
TorqueMaxUnderMinLim In angle control: the maximum torque set in the program is equal or
lower than the minimum limit of the screwdriver.
In torque control: The maximum torque set in the program is equal
or lower than the target torque already set.
TorqueMinOverMaxLim In angle control: the minimum torque set in the program is equal or
higher than the maximum torque already set.
In torque control: the minimum torque set in the program is equal or
higher than the target torque already set.
RevTorqueOverMax The reverse torque of this program is higher than the maximum
torque of the screwdriver.
RevSpeedOverMax The reverse speed is higher than the maximum allowed by the
screwdriver.
RevSpeedUnderMin The reverse speed is lower than the minimum allowed by the
screwdriver (50 RPM).
If the connection with the motor control board is successful the following screen will be displayed:
