2Safety instructions
All safety related regulations, local codes and instructions that appear in the manual or
on equipment must be observed to ensure personal safety and to prevent damage to
the equipment connected to it. If equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be impaired.
Do not stress the equipment over the specification limits neither during assembly nor
operation. To do so can be potentially harmful to persons or equipment in the event of a
fault to the equipment.
2.1 Presentation of safety information
The following safety symbols appear in this manual.
2.1.1 Danger that could result in minor or moderate injuries

2.2 General safety information
The Material Sensors may not be stressed over the specification
limits neither during assembly nor operation.
The attachment points for the Sensors on the machine frame must
be properly designed. The used mounting screws must be of the right
size.

3Product information
3.1 System description
The ultrasonic sensors can detect a very wide range of web materials including
transparent films. The sensors are not suitable for sound permeable materials (e.g. net-
like or open weave textiles). They are factory set and don’t need any adjustments or
calibration. The main advantage of these sensors is the save detection of transparent
films of all sizes. The sensor is almost insensitive to changes of material planarity or
dust thanks to an optimized sensor and micro-processor controlled ultra-sound
transmission.

4Installation
4.1 Preparation
The sensors are defined as “partly completed machinery” according to the Directives
2006/42/EC, article 2. In order to assure a proper functionality of the parts and
guarantee the essential health and safety requirements of operators working with it, the
following conditions for the assembly must be met:
4.2 General safety information
The Material Sensors may not be stressed over the specification
limits neither during assembly nor operation.
The attachment points for the Sensors on the machine frame must
be properly designed. The used mounting screws must be of the right
size.
For correct installation and operation, follow the electrical wiring
diagram and instructions in this manual.
4.3 Electrical connections
The sensor will be mounted with two M4 screws to a bracket. The bracket itself is fixed
to the location rail or to the flange of the steering frame or linear actuator. The bracket
varies depending on system configuration (steering frame size, manual or motorized
sensor adjustment, etc.). It is not part of supply and must be ordered separately.
If the sensor is used with an integrated web guide controller within an FMS steering
frame FMS-webMASTER, the sensor is connected with a cable 4x0.14mm
2
of the
respective length.

-Loosen the fixing nut on the bracket and adjust the sensor.
-The positioning marks provide a quick and precise alignment of the sensor to the
reference edge.
-Fix the sensor in the new position.
-The sensor will be properly positioned, if the web edge goes through the sensor axis
covering half of the ultrasonic transmitter or receiver (ref. to Fig. 4).

6Trouble shooting
Causes and possible solutions for errors
Description of error Cause Corrective action
Limited control range Edge has moved
outside the sensor
detection range
Adjust sensor more
accurately to the center of
the measuring range.
Occasional control dropouts Ultrasonic
transmitter or
receiver side is
dirty
Clean sensor with wet cloth
BKS guides web edge
immediately out of the
sensor detection area
Sensor is installed
on the wrong side
Install sensor on the correct
side (right sensor for „Edge
right“, etc.
Sensor is
connected to the
wrong socket
Connect sensor plug to the
correct socket (left plug to
left socket, etc.)
Steering frame does not
move at all
No signal; sensor
not connected
correctly
Connect sensor correctly
according to screw terminal
arrangement, follow the
installation manual of web
