Einführung
1. Introduction
The Kuhnke dialog terminals KDT 635 and KDT 633 have
been developed for menu-driven machine operation. The use
of these terminals makes operating state messages possible as
well as the entering of new settings into the control by the
machine operating personnel.
Their low construction, high protection (IP 65), low heat dissi-
pation and high durability make them well-adapted to a
mounting in close approximation to machines.
Data transfer between terminal and control is effected via a
V.24 interface.
Advantages of operator prompting
-Dialog-oriented communication between man and machine
-Digital input and output of the processing parameters
-Plaintext error diagnosis
-Graphic visualization of the process
MONIT or TEBES
In the shape of MONIT, a convenient software package is
available for creating pictures, masks and texts.
This program supports the communication between the control
terminals and all Kuhnke controls as well as those capable to
follow the 3964-R protocol.
TEBES is the follower of MONIT. TEBES runs under
Windows and therefore more transparent for the user. An
integrated simulation program allows to simulate the pictures
on the PC in online operation with the connected controller.

Einführung
Operating modes
In combination with Kuhnke controls and MONIT, the
terminals can be operated in two modes:
-Master mode
The terminal is directly conneted to the programming
interface. No further arrangements have to be made in the
user program.
-Slave mode
Only possible in combination with the controls KUAX 657,
657P and 653W. Communication is effected via a slave
processor with its own interface. All graphics and graphic
data are stored in the memory of the slave processor.

2.4. Safety
Our product normally becomes part of larger systems or install-
ations. The following notes are intended to help integrating the
product into its environment without dangers for man or mate-
rial/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
correspondto Europeanstandard EN60742 (corresponds to
VDE0551)
-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
restartthat excludes dangerousstates.
-Emergency switch-off installations or other emergency instal-
lations 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
dangerousmistakes or failures.
-The relevent standards and VDE regulations are to be ob-
served in every case.
-Control elements have to be installed in such a way as to ex-
cludeunintendedoperation.
-Control cables have to be layed in such a way as to exclude
interference (inductive or capacitive) which could influence
theoperation of thecontroller.
To achieve a high degree of conceptual safety in planning and
installing an electronic controller it is essential to follow the
instructions given in the manual exactly because wrong han-
dling could lead to rendering measures against dangerous fail-
ures ineffective or to creating additional dangers.

Safety and Reliability
2.4.2. To be observed during maintenance and servicing
-Precaution regulation VBG 4.0 must be observed, and §8
(Admissible deviations during working on parts) in particular,
when measuring or checking a controller in a power-up con-
dition.
-Repairs must only be made by specially trained Kuhnke staff
(usually in the main factory in Malente). Warranty expires in
every other case.
-Spareparts:
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 recognizably!) de-
tractedfrom 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 func-
tion 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 cer-
tain range occurs at the location of a given device. This noise
depends on the exact location. It is determined in the relevant
productstandards.
Theinternational standardregulating constructionand 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
-Electrostaticdischarge, ESD
in accordance with IEC 801-2, 3rd degree of sharpness
-Fasttransient 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)

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.
Appropriate means for keeping the corresponding limiting val-
ues are fitting the controller into an earthed metal cabinet and
equipping the supply cables with filters.
2.5.4. General notes on installation
As component parts of machines, facilities and systems, elec-
tronic control systems must comply with valid rules and regula-
tions, depending on the relevant field of application.
Generalrequirements concerning the electrical equipmentof
machines and aiming at the safety of these machines are con-
tained in Part 1 of European standard EN 60204 (corresponds
to VDE 0113).
For safe installation of our control system please observe the

Safety and Reliability
2.5.7. Location of installation
Makesure that thereare no impediments due to temperatures,
dirt,impact, vibrations and electromagnetic interference.
Temperature
Consider heat sources such as general heating of rooms, sun-
light, 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
Considerelectromagnetic interference from various sources
near the location of installation: motors, switching devices,
switching thyristors, radio-controlled devices, welding equip-
ment, arcing, switched-mode power supplies, converters / in-
verters.
2.5.8. Particular sources of interference
Inductive actuators
Switching off inductances (such as from relais, contactors, so-
lenoids or switching magnets) produces overvoltages. It is nec-
essary to reduce these extra voltages to a minimum.
Reducing elements my be diodes, Z-diodes, varistors or RC el-
ements. To provide suitably designed reducing elements, we
recommend asking the manufacturer or supplier of the corre-
spondingactuators for therelevant information.
