1Safety Instructions
1.1 Description Conditions
High danger of health
injury or loss of life Risk of damage
to machines Note for
proper function
Danger
This symbol refers to high risk
for persons to get health injury
or loss life. It has to be
followed strictly.
Caution
This symbol refers to risk of
heavy mecanical damage.
This warning has to be
followed absolutely.
Note
This symbol refers to an
important information about
proper use. If not followed,
malfunction can be the
result.
1.2 List of Safety Instructions
Proper function of the electronic unit is only guaranteed with the recommended
application of the components. In case of other arrangement, heavy malfunction can be
the result. Therefore, the installation instructions on the following pages must be followed
strictly.
Local installation regulations are to preserve safety of electrical equipment. They are not
taken into consideration in this operating manual. However, they have to be followed strictly.
Bad earth connection may cause electric shock to persons, malfunction of the total system
or damage of the electronic unit! It is vital to ensure that proper earth connection is done.
The processor board is mounted to the housing cover. Improper handling may damage the
fragile electronic equipment! Don’t use rough tools such as screwdrivers or pliers! Touch
processor board as little as possible! Touch earthed metal part to discharge static
electricity before opening the housing!
If external parts are in the travel range of the linear units, the sensors can be damaged
while moving! It is to ensure that large enough distances are kept allover.
With the line-up of the limit of travel positions, the software limit switches of the steering
frame or the unwinding roller are set. Bad setting may cause damage of the steering frame
or the unwinding roller! Therefore, the setting should only be made during the first initial
operation and by authorized and specially trained personnel only!
Wrong setting of the jumpers and solder bridges may cause malfunction of the electronic
unit or the total system! Setting of the solder bridges and jumpers must be checked
carefully prior to power on! Setting of the solder bridges should be carried out by trained
personnel only!

2Definitions
Left and Right: Left and right are always seen in direction of the running web.
Linear unit: Motorized Sensor adjustment (option). The sensor is adjusted automatically by a
linear guide with stepper motor to the edge or line to be detected.
Steering device: Hydraulic cylinder, steering frame or similar actuator.
Dead band: A free programmable range of tolerance in which the web may move freely
without readjusting the steering device. Keep in mind that „0.3mm“ means ±0.3mm.
If the deviation is higher than the tolerance, the web will be readjusted into the range of the
dead band.
Subprint: Electronic extension module which can be plugged to the main board of the
electronic unit if required. That way, the possibilities of the electronic unit can be extended
easily.
3System Components
A BKS600A web guiding system consists of the following components (refer also to fig. 1):
Steering device
•Electrically or hydraulically driven
Electronic unit BKS600A
•For all control functions
•With operation panel for parametrization
•Steering frame with DC motor or analog control output
±10V / 0...10V / 0...20mA / 4...20mA
•Power amplifiers for the stepper motors of the linear units
•Interface RS232, PROFIBUS, CAN-Bus, DeviceNet
•Digital inputs and outputs
•Remote control box
•With robust aluminium housing
Sensors
•For detection of web edge
•1 or 2 analog sensors
Linear units
•linear units with two phase stepper motor and limit switch for reference
(components and variants in italic letters are options)

4System Description
fig. 1: Basic structure of the BKS600A web guide K600023e
4.1 Functional Description
The sensors measure the position of the web edge and send this information as an analog
signal to the electronic control unit. The control unit compares the position feedback signal
with the reference. If the difference is higher than a parametrized value (dead band), the
steering device is adjusted to bring the web into the right position.
If the sensors are equipped with linear units, the control unit automatically lets them follow the
edge. The actual position of the sensors on the linear unit is taken into calculation for the
actual web position.
4.2 Steering device
The steering device adjusts the web position laterally. Its width is depending on the web
width. Any steering device can be used if it can handle the signal for an FMS steering frame
with DC motor drive:
−FMS steering frame with DC drive
−any actuator with analog input ±10V / 0...10V / 0...20mA / 4...20mA
−Optionally: ±300mA / ±10V for a moving coil controller (hydraulic actuator)

4.3 Electronic Control Unit
Common
The electronic unit is mounted to a robust aluminium housing. It contains the power amplifier
to drive the actuator and the power amplifiers to drive the linear units. The electronic unit has
no trimmers and only few jumpers to keep most accurate long-time and temperature stability.
Operation
The large backlit display with 2x16 characters, 4 LED’s and large keys guarantee simple
operation. All information is in plain text with the following languages selectable: English,
German, French and Italian. Most of the functions may be paramterized. The parametrization
can be done via the keys or the interfaces. All inputs are fail-safe stored in an EEPROM.
Additional settings can be made with jumpers or solder bridges.
Interface
As an option, there are RS232, PROFIBUS, CAN-Bus or DeviceNet interfaces available. All
inputs and settings can be made by the integrated operation panel or by the interfaces.

4.4 Edge Sensors
An optical sensor (AZS01) and an ultrasonic sensor (US01) is available from FMS.
Adjustment is done automatically.
4.5 Manual Sensor Adjustment
The manual sensor adjustment allows an easy positionning of the sensor across the whole
material width. Focussing of the sensor is kept.
4.6 Linear Units
The linear units are also used for sensor positioning but give much more comfort than the
manual one. The control unit automatically lets the sensors find the edge or the line across the
whole material width.
This kit contains 1 or 2 linear units with travel range according to customer specification, the
sensor mounting bracket and the necessary cables. The control unit detects automatically if 1
or 2 linear units are installed.
It is possible to define a fixed reference point (machine frame for example). Then, all position
values will refer to this reference point.
4.7 Remote Control Box
The remote control box simplifies resetting the machine for a new job. The position reference
can be adjusted with two keys on the box in 0.1mm steps. It enables the operator to stand
beside the machine and get a direct feedback when adjusting the lateral position.

5Quick Installation Guide
•Check all your requirements such as:
– Control mode (edge left, edge right, center guiding)?
– Number and setup of the edge sensors?
– Steering device type (FMS steering frame, hydraulic drive or other device)?
(if a linear DC drive for unwind or rewind stands is used it must be setup; refer to
„9.7 Line-up of the limit positions and Offset Compensation“)
– configuration of the digital inputs and outputs?
– linking by interface etc.?
•Draw your final wiring diagram according to the wiring diagram (refer to „7.2 Wiring
diagrams“)
•Install and wire all your components (refer to „7. Installation and wiring“)
•Turn power on and do the setup according to „8. Operating“
•Proceed a test run with low speed

7Installation and Wiring
Caution
Proper function of the electronic unit is only guaranteed with the recommended application of
the components. In case of other arrangement, heavy malfunction can be the result. Therefore,
the installation instructions on the following pages must be followed strictly.
Caution
Local installation regulations are to preserve safety of electrical equipment. They are not taken
into consideration in this operating manual. However, they have to be followed strictly.
Caution
Bad earth connection may cause electric shock to persons, malfunction of the total system or
damage of the electronic unit! It is vital to ensure that proper earth connection is done.
7.1 Mounting the Electronic Unit
The housing can be mounted in a control cabinet or directly beside the machine. All
connections are led into the housing through glands and are connected to the plug-in screw
terminals according to the wiring diagrams (fig. 7...12).
