Safety 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
Danger, warning, caution
Failure to follow wiring instructions in this manual may result in equipment damage or personal injury.

Note regarding proper operation Simplification of operation Ensuring function
General safety information
The Material Sensors may not be stressed over the specification limits either during assembly or 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.
Product 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. netlike 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.

Installation
4.1 Preparation
The sensors are defined as “partly completed machinery” according to the Directives 2006/42/EC, Article
2. In order to assure 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 either during assembly or 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 the 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 4×0.14mm2 of the respective length.

Table 4: Sensor alignment
– 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).
Troubleshooting
Causes and possible solutions for errors
| Description of error | Cause | Corrective action |
| Limited control range | Edge has moved outside the sensor detection range | Adjust the sensor more accurately to the center of the measuring range. |
| Occasional control dropouts | Ultrasonic transmitter or receiver side is dirty | Clean sensor with a wet cloth |
| BKS guides web edge immediately out of the sensor detection area | The 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 the left socket, etc.) | |
| The 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 guide controller |
| No signal; cable interruption | Replace the cable or send the sensor to FMS | |
| No signal; sensor defect | Send sensor to FMS; use another sensor | |
| No power supply | Check 24VDC supply | |
| The sensor signal is OV. The sensor is fully covered | Adjust sensor more accurately to the web edge; center measuring range | |
| The sensor signal is 10V. The sensor is uncovered | Adjust sensor more accurately to the web edge; center measuring range |
