1. Introduction
KUAX 680I, KUAX 680C and KDT 680 CT are efficient,
modularly constructed minicontrollers. They are equipped with
modules which communicate with the user program in the controller either directly or via transfer addresses (SLx...). KUAX
680C and KDT 680CT also have built-in inputs and outputs
which are not, however, described in this instruction manual.
There are connectors for three-conductor connections so that
proximity switches or other similar devices can be supplied via
the same cable as the signal line. Additional terminal strips are
thus made redundant. Simply plug the modules into the appropriate slots from above:

2. Safety and Reliability
2.1. Target group
This instruction manual contains all information necessary for
the use of the described product (control device, software, etc.)
according to instructions. It is written for the personnel of the
construction, project planning, service and commissioning
departments. For proper understanding and error-free applica-
tion of technical descriptions, instructions for use and particularly of notes of danger and warning, extensive knowledge of
automation technology is compulsory.
2.2. Reliability
Reliability of Kuhnke controllers is brought to the highest possible standards by extensive and cost-effective means in their
design and manufacture.
These include:
selecting high-quality components,
quality arrangements with our sub-suppliers,
measures for the prevention of static charge during the handling of MOS circuits,
worst case dimensioning of all circuits,
inspections during various stages of fabrication,
computer aided tests of all assembly groups and their
coefficiency in the circuit,
statistic assessment of the quality of fabrication and of all returned goods for immediate taking of corrective action.
Safety and Reliability
Despite these measures, the occurrence of errors in electronic
control units - even if most highly improbable - must be taken
into consideration.

Safety and Reliability
2.4. Safety
Our product normally becomes part of larger systems or installations. The following notes are intended to help integrating the
product into its environment without dangers for man or material/equipment.
2.4.1. To be observed during project planning and installation
- 24V DC power supply:
Generate as electrically safely separated low voltage. Suitable
devices are, for example, split transformers constructed to
correspond to European standard EN 60742 (corresponds to
VDE 0551)
- In case of power breakdowns or power fades: the program has
to be structured in such a way as to create a defined state at
restart that excludes dangerous states.
- Emergency switch-off installations or other emergency installations have to be realized in accordance with EN 60204/
IEC 204 (VDE 0113). They must be effective at any time.
- Safety and precautions regulations for qualified applications
have to be observed.
- Please pay particular attention to the notes of warning which,
at relevant places, will make you aware of possible sources of
dangerous mistakes or failures.
- The relevent standards and VDE regulations are to be observed in every case.
- Control elements have to be installed in such a way as to exclude unintended operation.
- Control cables have to be layed in such a way as to exclude
interference (inductive or capacitive) which could influence
the operation of the controller.
To achieve a high degree of conceptual safety in the planning
and installation of electronic controllers it is essential to follow the instructions given in the manual exactly because wrong
handling could lead to rendering measures against dangerous
failures ineffective or to creating additional dangers.
2 - 3
Safety and Reliability
2.4.2. To be observed during maintenance and servicing
- Precaution regulation VBG 4.0 must be observed, and section
8 (Admissible deviations during working on parts) in particular, when measuring or checking a controller in a power-up
condition.
- Repairs must only be made by specially trained Kuhnke staff
(usually in the main factory in Malente). Warranty expires in
every other case.
- Spare parts:
Only use parts approved of by Kuhnke. Only genuine Kuhnke
modules must be used in modular controllers.
- Modules must only be connected to or disconnected from the
controller with no voltage supplied. Otherwise they may be
destroyed or (possibly not immediately recognisably!) detracted from their proper functioning.
- Always deposit batteries and accumulators as hazardous
waste.

2.5. Electromagnetic compatibility
2.5.1. Definition
Electromagnetic compatibility is the ability of a device to function satisfactorily in its electromagnetic environment without
itself causing any electromagnetic interference that would be
intolerable to other devices in this environment.
Of all known phenomena of electromagnetic noise, only a certain range occurs at the location of a given device. This noise
depends on the exact location. It is determined in the relevant
product standards.
The international standard regulating construction and degree
of noise resistance of programmable logic controllers is IEC
1131-2 which, in Europe, has been the basis for European
standard EN 61131-2.
2.5.2. Resistance to interference
Safety and Reliability
Electrostatic discharge, ESD
in accordance with IEC 801-2, 3rd degree of sharpness
Fast transient interference, Burst
in accordance with IEC 801-4, 3rd degree of sharpness
Irradiation resistance of the device, HF
in accordance with IEC 801-3, 3rd degree of sharpness
Immunity to damped oscillations
in accordance with IEC 255-4 (1 MHz, 1 kV)
2 - 5
Safety and Reliability
2.5.3. Interference emission
Interfering emission of electromagnetic fields, HF
in accordance with EN 55011, limiting value class A, group 1
If the controller is designed for use in residential districts, then
high-frequency emissions must comply with limiting value class
B as described in EN 55011.
Fitting the controller into an earthed metal cabinet and equipping the supply cables with filters are appropriate means for
keeping the corresponding limiting values.
2.5.4. General notes on installation
As component parts of machines, facilities and systems, electronic control systems must comply with valid rules and regulations, depending on the relevant field of application.
General requirements concerning the electrical equipment of
machines and aiming at the safety of these machines are contained in Part 1 of European standard EN 60204 (corresponds
to VDE 0113).

eliminate electromagnetic interference. Ensure practical wiring
and laying of cables.
2.5.6. Cable routing and wiring
Separate laying of power supply circuits, never together with
control current loops:
DC voltage 60 V ... 400 V
AC voltage 25 V ... 400 V
Joint laying of control current loops is allowed:
data signals, shielded
analogue signals, shielded
digital I/O lines, unshielded
DC voltages < 60 V, unshielded
AC voltages < 25 V, unshielded

Safety and Reliability
2.5.7. Location of installation
Make sure that there are no impediments due to temperatures,
dirt, impact, vibrations and electromagnetic interference.
Temperature
Consider heat sources such as general heating of rooms, sunlight, heat accumulation in assembly rooms or control cabinets.
Dirt
Use suitable casings to avoid possible negative influences due
to humidity, corrosive gas, liquid or conducting dust.
Impact and vibration
Consider possible influences caused by motors, compressors,
transfer routes, presses, ramming machines and vehicles.
Electromagnetic interference
Consider electromagnetic interference from various sources
near the location of installation: motors, switching devices,
switching thyristors, radio-controlled devices, welding equipment, arcing, switched-mode power supplies, converters / inverters.
2.5.8. Particular sources of interference
Inductive actuators
Switching off inductances (such as from relays, contactors, solenoids or switching magnets) produces overvoltages. It is necessary to reduce these extra voltages to a minimum.
Reducing elements my be diodes, Z-diodes, varistors or RC elements. To provide suitably designed reducing elements, we
recommend asking the manufacturer or supplier of the corresponding actuators for the relevant information.

3. Modules and slots
KUAX 680I and 680C can be equipped with different types of
modules. The number of modules depends on the size of the
device:
- Devices with 4 slots: 4 modules (slots 0...3)
- Devices with 8 slots: 8 modules (slots 0...7)
(KUAX 680I only)
Modules are plugged into the top of the device. They are connected to the controller via the device bus plug (the figure below shows KUAX 680I):
Module

Device bus plug
The following has to be observed when placing the modules:
- Only plug modules in/out in an idle state. Danger of destruction!
- Sequence modules from left to right (see also "3.3. Slots").
- The modules must be screwed into the device. They could otherwise become loose and then cause dangerous conditions.

Modules
3.1. Design
Mounting
Labels
Status indicators
The modules are enclosed in a plastic casing. For cooling the
electronics, there are ventilation slots on the narrow edges. The
plug for the connection to the bus connector is on the bottom
side.
There is a screw sunk into the front side which is used to attach
the module to the device frame.
In KUAX 680C, KDT 680CT, and recent models of KUAX 680I
(part numbers 680.423.xx) the modules are additionally supported by plastic rests. Modules made before calendar week
27/95 do not fit into these devices because they have no bores
to place the plastic rests in.
A large area on the front side is saved for a label. The label can
be used to enter the symbolic designations of the input or output signals (cf. symbol table under KUBES) or the function of
the module.
There is a sufficient number of labels. They are delivered together with the KUAX 680I as perforated A4 tear-off blanks.
The line and column spacings are set in a way that makes an
inscription possible also for dot-matrix printers with a condensed print.
On the lefthand side of the labels there are left as many holes
as the module provides status indicators.
These holes fit across LEDs which are built into the actual
module casing to indicate, for example, signal states of inputs
or outputs.
By definition, light emitting diodes (also referred to as LEDs)
are "Class 1 light emitting diodes (in acc. with EN 60825_1)".
Channel numbers
3 - 2
On input and output modules, the corresponding channel numbers (0...3/7) are printed left to the LEDs. They correspond to
the inscription on the signal strip underneath the module. The
relation between terminal, LED and inscription is thus documented.
3.2. Screw-type locking connectors
Screw-type locking connectors (supplied by Phoenix) are used
to connect inputs and outputs to the device:
Connector type MINI-COMBICON, 3.81 mm matrix, connecting diameter 0.14...1,5 mm² , max. load 8 A
The green screw-type locking connectors sit very firmly in
their position to avoid them becoming loose due to vibrations.
Should you find it difficult to pull them off with your fingers,
simply use a flat object such as a screwdriver with a wide blade
as a lever.
Never pull the wires to disconnect the plug. The wires might
otherwise slip out of the terminals or rip off even.
3.2.1. Coding
You can code the MINI-COMBICON connectors so that you do
not get them confused when putting them on (by conntecting
digital inputs to an SSI module, for example).
Push one or several coding profiles into the groove(s) provided
on the socket part of the connector for this purpose. Use a side
cutter, for example, to cut the corresponding coding element
off the plug part.

There are some connectors in the basic device which are coded
in the factory. Please refer to the corresponding illustrations to
learn where such codings exist and what they look like.

Modules
3.3. Slots
KUAX 680I can be equipped with slots for either 4 or 8 modules. KUAX 680C and KDT 680CT always have 4 slots (or
none).
3.3.1. Function slots
Individual slots carry additional leads. They make the application of certain modules possible for using services provided by
the processor (counting, stepper motor control, analogue/digital
conversion...):

These specifications do not limit the application of any other
module. If a function slot is not needed as such, it can also be
used for a slot-independent module such as a digital input or
output module.
*1) PWM stands for "pulse-width modulated output" for stepper motor control.
*2) This only concerns those analogue inputs with a resolution of 10bit that use the
A/D converter on the CPU.

3.4. Service modules
Modules with more complex functions need software support to
be able to carry out these functions. In order to avoid the necessity for the user to write these often very complicated programs
himself, so-called service modules are embedded in the program to relieve the user.
As from release 4.00, these service modules are delivered with
KUBES as individual files under the name SERV_xx.BIN. The
KUBES installation program places these files in the same subdirectory as the program files (e.g. C:\KUBESEXE).
Configuration
When configuring KUAX 680I or 680C, you enter the modules
into a list in the same order in which they will be plugged in
later. KUBES can use this information to embed the necessary
service modules in the user program and to create the reference
to the modules.
3.4.1. Transfer address ranges
Service modules use so-called transfer address ranges (max. 32
byte) for each module for data exchange with the user program.
These are directly assigned to the module slots (see table on
next page). The service module assigned to the slot during configuration determines the assignment of the transfer addresses.
Service modules
3.4.2. Interrupt modules
Under certain conditions, some modules trigger an interrupt in
the CPU. Like this the service module, and sometimes also the
user program, can react particularly quickly to an event. An interrupt caused by a module calls up an interrupt module (see table on next page). This module can contain user-defined instructions to be carried out in case of an interrupt.

3.5. Power supply of inputs and outputs
All inputs and outputs as well as the relay for polarity safeguarding in the digital output modules are centrally supplied
via the corresponding terminals of the basic device (see the relevant instruction manuals of the individual controllers).

3.6. Differences between KUAX 680C/KDT 680CT and KUAX 680I
All examples given in this instruction manual refer to the use
of the relevant modules in KUAX 680I.
When working with KUAX 680C or KDT 680CT you will be
obliged to take note of some differences which are caused by
the I/Os available to the basic device.
Limited applicability
- You cannot use the counter module for event counters, order
no. 680.454.03; the reason being that in its standard configuration, the device is already equipped with two event
counters (internal inputs).
- Stepper motor modules and internal analogue outputs share
the same system resources, i.e. the PWM outputs of the processor:
PWM analogue output stepper motor module
1 AO00.00 680.444.01 and .02
2 AO00.01 680.444.02
Thus, if you are using a two-channel stepper motor module
(680.440.02) neither of the two internal analogue outputs can
be used. If you are working with a single-channel stepper
motor module (680.440.01), you still have the option of using internal analogue output AO00.01 at least.
Addressing
Please note that input and output groups are occupied already
by the internal I/Os. While plugged-in modules are numbered
in groups from left to right just like in KUAX 680I, they start
with different group numbers:
Modules first group
digital inputs I02
analogue inputs AI01
digital outputs O02
analogue outputs AO01
For further information please refer to the device manuals.
