1Safety Instructions
1.1 Description conditions
a) High danger of health injury or loss of life
Danger
This symbol refers to high risk for persons to get health injury or loss life. It has to be
followed strictly.
b) Risk of damage of machines
Caution
This symbol refers to informations, that, if ignored, could cause heavy mecanical damage.
This warning has to be followed absolutely.
c) Note for proper function
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 FMS web guide is only guaranteed with the recommended
application of the components. In case of other arrangement, heavy malfunction can be
the result. Therefore, the installation instrucions on the following pages must be followed
strictly.
Local installation regulations are to preserve safety of electric equipment. They are
not taken into consideration by 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 control unit! It is vital to ensure that proper earth connection is
done.
The processor board is mounted directly behind the operation panel. Improper
handling may damage the fragile electronic equipment! Don’t use rough tools as
screwdrivers or pliers! Don’t touch processor board! Touch earthed metal part to
discharge static electricity before removing operation panel!
Disconnect power supply before open the housing!

2Definitions
Left and Right:
Left and right are always seen in direction of
the running web (fig. 1).
3System Components
The BKS010 consists of the following components (refer also to fig. 2):
Steering frame
•According to the maximum web width
•Driven by a DC-Servo-Motor
•With integrated location slot for sensor attachment
Electronic control unit
•For all control functions
•With operation panel for all functions
•The control unit is integrated to the steering frame and pre-wired. The housing complies
with IP20
Sensors
•For edge detection
•1 or 2 analogue Sensors
•The sensors are full wired and equipped with a plug with fixing thread M8x1.
•Included are 2 Sensor brackets for left or right edge detection

4System Description
fig. 2: Basic structure of the BKS100 web guide K100006e
4.1 Functional description
The sensors locate the position of the web edge and send this information as an analogue
signal to the electronic control unit. The control unit compares the position feedback signal
with the reference. If there is a difference the steering frame will be adjusted.
4.2 Steering frame
The steering frame consists of a fixed lower and a moveable upper frame that supports the
rollers. The upper frame is activated by a DC-Servo-Motor. A location slot for easy sensor
attachment is integrated to the steering frame.
4.3 Electronic control unit
The electronic control unit contains a micro-processor that handles all calculations and
communications. The DC-Servo-Motor to drive the steering frame, the rotary switch and
potentiometer are integrated.
4.4 Analogue sensors
Adjustment is done automatically. The sensors provide a signal of 0...10V. Edge and center
guiding (2 sensors) applications can also be done.

6Installation and Wiring
Caution
Proper function of the FMS web guide 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 electric equipment. They are not taken
into consideration by this operating manual. However, they have to be followed strictly.
6.1 Mounting the Steering Frame
When mounting the steering frame, the direction indicated on the frame side must correspond
with the web running direction.
The fixed lower frame can be easily fitted to the machine frame with the overhanging part.
Attach the appropriate sensor brackets to the sensors and then to the frame before installing
the frame on the machine.
The steering frame BKS010 is pre-wired; therefore is no wiring other then a 24V power
connection necessary by the customer.
6.2 Connecting the Electronic Control Unit
Connect 24VDC (18…36), min. 0.5A to electronic unit. Connect according to fig. 8.
Caution
Bad earth connection may cause electric shock to persons, malfunction of the total system or
damage of the control unit! It is vital to ensure that proper earth connection is done.

6.3 Mounting the Sensors
fig. 4: Position of the sensors according to the web K400005e
The sensors will be mounted by brackets to the integrated location slot of the steering frame.
Note
Take care that the plugs are connected properly (plug sensor left to socket left, etc.; refer to
fig. 5). If the plugs are exchanged, malfunction can be the result.

6.4 Open the housing
The housing of the electronic control unit can be opened by unscrewing the 4 philips screws
on the operation panel and pulling out the operation panel carefully.
Caution
The processor board is mounted directly behind the operation panel. Improper handling may
damage the fragile electronic equipment! Don’t use rough tools as screwdrivers or pliers!
Don’t touch processor board! Touch earthed metal part to discharge static electricity before
removing operation panel!
Caution
Disconnect power supply before open the housing!

Control mode Function
Edge left [The control unit drives the steering frame in a way that the left edge
will follow to the reference position.
1 left sensor is necessary.
Edge right ]The control unit drives the steering frame in a way that the right edge
will follow to the reference position.
1 right sensor is necessary.
Center guide [ ] Guiding to the average value from left and right. This means the
theoretical center line.
2 sensors are necessary.
Center Frame moves to the center
Reference Potentiometer To adjust the reference position in runtime
7.2 Adjustment of the sensors
•Align sensor axis to the web edge: Loosen
the fixing knob on the bracket and adjust
the sensor. Fix the sensor in the new
position. The sensor will be positioned
properly if the web edge goes through the
sensor axis (center of active window; refer
to fig. 6)
•Reference position is taken from the center
of the sensor detection band (fig. 7). Using
center guide, reference position is in the
middle between the 2 sensor axis. The
controller starts to guide the web to
reference position and to hold this guide
point.
•The reference position can be adjusted
during operation by using the
potentiometer.
Note
If the web leaves the sensor detection band, control is no longer effective. Hold the web
edge strictly inside the sensor detection band.
Note
If web is not running, it can’t be guided properly to the reference position! The steering
frame moves in the limit-of-travel position and may damage the web.
