Ultrasonic Sensors

The sks sensor offers a non-contact measurement of the distance to an object which must be positioned within the sensor’s detection zone. The switched output is set in dependence of the adjusted detect distance. Via the push-button, the detect distance and operating mode can be adjusted (teach-in). Two LEDs indicate operation and the state of the switched output. The output function is changeable

Safety Notes

■ Read the operating instructions

prior to start-up.

■ Connection, installation and

adjustment works may only be carried out by expert personnel.

■ No safety component in

accordance with the EU Machine Directive

Proper use

sks ultrasonic sensors are used for non-contact detection of objects.

Installation

■ Mount the sensor at the installa-

tion site. Maximum torque: 0,5 Nm

■ Connect a connection cable to the M8 device plug.

Start-Up

■ Connect the power supply.

■ Carry out the adjustment in

accordance with the diagram.

Factory Setting

■ Operation with one detect point

■ Switched output on NOC

■ Detect points at operating range

Operating modes

Three operating modes are available for the switched output:

■ Operation with one detect point

The switched output is set if the object falls below the set detect point.

■ Window mode

The switched output is set if the object is within the set window margins.

■ Two-way reflective barrier

The switched output is set if the object is between sensor and reflector.

Checking operation mode

■ In normal mode shortly press the

push-button.

The green LED stops shining for one second, then it will show the current

operation mode:

1 x flashing = operation with one

switching point 2 x flashing = window mode 3 x flashing = reflective barrier

After a break of 3 s the green LED shows the output function:

1 x flashing = NOC 2 x flashing = NCC

Maintenance

microsonic sensors are maintenancefree. In case of excess caked-on dirt we recommend cleaning the white sensor surface

Notes

■ sks-15/CD and sks-15/CE sensors

have internal temperature compensation. Because the sensors heat up on their own, the temperature compensation reaches its optimum working point after approximatly 30 minutes of operation. The sensors sks-15/D and sks-15/E have no temperature compensation.

■ The sks sensor has a blind zone,

within which distance measurements are not possible.

■ In the normal operating mode, an il-

luminated yellow LED signals the switched output is switched through.

■ If the object to be sensed moves

into the detection area from the side, the switching distance should be set 8-10 % further than the desired switch point to obtain a reliable object detection. If the object moves towards the sensor (e.g. level control) the detect point can be taught to the actual distance at which the sensor has to switch the output.

Resolution, sampling rate

The dark grey areas are determined

with a thin round bar (10 mm dia.)

and indicate the typical operating range of a sensor. In order to obtain the light grey areas, a plate (100 x 100 mm) is introduced

into the beam spread from the side.

In doing so, the optimum angle between

plate and sensor is always employed.

This therefore indicates the maximum

detection zone of the sensor.

It is not possible to evaluate ultrasonic

reflections outside this area.

■

In the »Two-way reflective barrier« operating mode, the object has to be within the range of 0-85 % of the set distance.

■ If the push-button is not pressed

for 10 minutes during the teach-in setting, the settings made hitherto are deleted.

■ The sensor can be reset to its fac-

tory setting.
