1General information
1.1 Intended use
The SK11 and SK20 turned tool changing stations are space-saving tool storage units with tool
slots arranged in a circle. The SK11 turned tool changing station is designed to hold and
temporarily store up to 12 milling and/or machining tools with SK11 tool holding fixtures. The SK20
changing station can accommodate up to 14 milling and/or machining tools. After actuation by the
operator, the automatic tool release takes place from a freely selected storage slot. Please refer to
the technical data for more precise features of the tools. The control of the changing station takes
place by means of the TCHUni.dll file offered by ISEL. The changing station has internal power
electronics and offers the possibility of connecting external components to an I/O interface.
General information:
Carefully read the entire assembly manual and follow the instructions. Non-observance of this
assembly manual can result in property damage, severe bodily injury, or death.
All important information about the assembly, programming, and operation of your SK11 or SK20
turned tool changing station can be found in this manual. It also provides you with important
information and notices for your safety.
1.2 Safety instructions
The SK11 and SK20 turned tool changing stations are designed
according to the state of the art and generally recognised good
engineering principles.
The equipment may only be operated in technically fault-free
condition. Faults must be rectified immediately. Children and
untrained persons may not commission the equipment.
The equipment may only be used for the intended purpose:
Changing station for milling tools with SK11 holding fixture for
SK11 turned tool changing station and SK20 holding fixture for
SK20 turned tool changing station. Control takes place by means
of the TCHUni.dll file offered by ISEL.
Do not reach into the turned tool changing station as long as the
machine is switched on and the compressed air is connected.
Prevent fires which can occur due to excessively hot tools in the
turned tool changing station.

Connection to compressed air supply
The turned tool changer requires an operating pressure of 8 bar and must be connected to
a maintenance unit. Required hose diameter 6mm.
4Assembly and commissioning
4.1 Assembly of turned tool changing station SK11, SK20
Ensure that you have a stable and secure foundation for the turned tool changing
station prior to commissioning. Avoid collision with other components of the
machine.
4.1.1 SK11 assembly
Figure 2: SK11 fastening
Fasten all five fastening points on the turned changer to the
mounting area of your machine with machine screws (not included
in the scope of supply) and ensure that it is flat and level.
Attention: The turned changer must be positioned in the
travel range of your CNC machine.

4.1.2 SK 20 assembly
Figure 3: SK20 fastening
4.2 Establishing connections
Attention! Switch off the mains voltage and pull out the mains plug before
connecting the tool changer! Shut off the compressed air and ensure the
absence of pressure!
Only authorised, qualified experts may carry out work on the electrical
equipment of the machine. After completion of the integration of the
turned tool changing station and prior to the initial commissioning, the
machine must undergo inspection in accordance with EN 60204-1:2006,
section 18.7. Route the cable without crossing other high-voltage cables.
Avoid sharp bends and corners when routing the cable and ensure that the
cable is not pinched and cannot be damaged as a result of movements of
the machine. Only use suitable cable guidance systems.
Fasten all six fastening points on the turned changer to the
mounting area of your machine with machine screws (not included
in the scope of supply) and ensure that it is flat and level.
Attention: The turned changer must be positioned in the
travel range of your CNC machine.

System IN interface
1)
Connect the 15 pin Sub D of the orange cable to the
System IN
slot on the turned changer.
Route the cable into the switch cabinet.
2)
Figure 4: X3 terminal strip on the last output stage
Disconnect the black AMP plug
strip, STOP1 OUT, STOP2 OUT, …
to Logic GND at terminal X3 of the
last output stage IMD 10/20/40.
3)
Plug in the black AMP plug of the
turned changer at this position.
Ensure that the colours match
(brown and green must be the
same).

Figure 5: Connection to the safety circuit module
Connect the System OUT cable to
the appropriate jack on the turned
changer and route the cable to
the SKM-S1.2-E safety circuit
module in the switch cabinet.
White and black wires are already
connected at terminals X5:E1.3
and X5:E1.4 (standstill monitor of
motor modules without turned
changer). Disconnect these and
make the following connections.
white -> X5:E1.3, Stop1 IN
brown -> X5:E1.4, Stop2 IN

5)
Figure 6: Voltage supply diagram
Establishing voltage supply:
The turned tool changing station
also requires a 24V DC voltage
supply.
We recommend using a 24V
power supply unit with at least
100 watts. The voltage
connection must be made after
the main contactors
(disconnection on Emergency
STOP).
Establish the connections as
follows:
white/blue +24V
white/green and brown/green GND
The green/yellow conductor
must be connected to the
machine's protective earth
conductor.
5)
Insulate the open ends of conductors which are not needed, or completely disconnect and
remove them.
6)
Connect the COM interface to the control computer (iPC15 / iPC25).
7)
Ensure that there is an appropriate compressed air connection.
8)
Connect any accessories via the external I/O interface.
Ensure that there is a sufficient protective circuitry of the outputs with the use of
inductors, e.g. self-induction recuperation diodes.

4.3 Commissioning
Commissioning takes place with the isel ProNC software.
You should check all settings and adapt them to your tool changer.
Start ProNC,
under the menu
Settings
->
Control unit
->
Tool management
->
Changing station 1
you will find
Setup
Follow the window step-by-step (tab by tab) and adjust the necessary settings.
Here you enter your tool
changing station type.
Select the number of tool
slots.

Determine the direction
from which the tool
changer should run.
Specify the minimum
clearances before critical
movements here.
Adjust the I/Os. For this
purpose, pay attention to
the Help in ProNC.

Turned tool changing station SK11 and SK20
18 / 27 April 2019
You configure your tool
changer here. Enter the
start and/or end position of
the tool changer,
specify the interface, and
specify the individual tool
slots. Also use the detailed
Help in ProNC.
By clicking on
Parameters
you can change the speed
setting for the changing
station.
Specify the number of steps
required for a complete
rotation of the tool changer
as follows:
Gear reduction x motor step
resolution
For SK20:
5400 steps per rotation
For SK11:
800 steps per rotation
This provides the
advantage of moving the
tool changer over the
shortest path to reach the
tool.
Specify the speeds for the
tool change.

4.3.1 Teaching in the tool slots
You must define each individual tool slot in the turned tool changer. For this purpose, we recommend
arranging tool slots increasing in ascending order, beginning with 1. However, the storage slots may
also be freely assigned.

Move the turned tool changer until storage slot 1 is centred in the tool change opening.
Attention: Do not reach into the moving changing station. Danger of severe
injury.
For better control: Both tappets of the tool holder must be above the pressure plate of the ejection
cylinder.
Check the positioning of the storage slot. If everything is correct and the tool can be driven out
without danger or damage, adopt the position.
Approach the 2nd storage slot. It must also be centred in the tool change opening. Perform the same
check of the tappet as with the first storage slot.
Adopt the position and proceed with the other positions in the same manner as with storage slots 1
and 2.
When all storage slots have been taught in, please check again whether the individual positions of the
tools have actually been "ADOPTED".
For this purpose, have the turned changing station repeatedly approach the various storage slots and
check the position of the toolholder in the tool change opening.
