Microsonic lcs+340-F User Manual

Operating Instructions

Ultrasonic proximity switch with one switched output and IO-Link interface

lcs+340/F lcs+600/F

Product description

The lcs+ 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 conditional upon the adjusted detect distance. Via the Teach-in procedure, the detect distance and operating mode can be adjusted. One LED indicates operation and the state of the switched output. The lcs+ sensors are IO-Link-capable in accordance with IO-Link specification V1.0.

accordance with the EU Machine Directive.

Use for intended purpose only

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

Installation

 Mount the sensor at the place of

fitting.

 Connect a connection cable to the

M12 device plug.

Start-up

 Connect the power supply.  Carry out sensor adjustment in

accordance with the diagram.

Operating modes

black white

Sync grey

 Operation with one detect point

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

 Window mode

The switched output is set when the object is within the set window.

 Two-way reflective barrier

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

≥ 2,00 m ≥ 18,00 m

≥ 4,00 m

≥ 30,00 m

Synchronisation

If under multiple sensor operation the assembly distance falls below the values shown in Fig. 2, the internal synchronisation should be used. For this purpose interconnect each pin 5 of max. 10 sensors.

Maintenance

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

Notes

 The sensors of the lcs+ family have

a blind zone, within which a distance measurement is not possible.

 The lcs+ sensors are equipped

with an internal temperature compensation. Due to the sensors self heating, the temperature compensation reaches its optimum working-point after approx. 30 minutes of operation.

 In the normal operating mode, an il-

luminated yellow LED signals that the switched output is switched through.

 The lcs+ sensors have a push-pull

switched output.

 In the »Two-way reflective barrier«

operating mode, the object has to be within the range of 0-85 % of the set distance.

 In the »Set detect point – method

A« Teach-in procedure the actual distance to the object is taught to the sensor as the detect point. If the object moves towards the sensor (e.g. with level control) then the taught distance is the level at which the sensor has to switch the output.

 If the object to be scanned moves

into the detection area from the side, the »Set detect point +8 % – method B« Teach-in procedure should be used. In this way the switching distance is set 8 % further than the actual measured distance to the object. This ensures a reliable switching distance even if the height of the objects varies slightly.

detection zones

The dark grey areas represent the zone

where it is easy to recognise the normal

reflector (round bar). This indicates the typical

operating range of the sensors. The light

grey areas represent the zone where a

plate – can still be regognised.. The

requirement here is for an optimum

alignment to the sensor. It is not

for different objects:

good reflector – for instance a

possible to evaluate ultrasonic

reflections outside this area.
