Ultrasonic Sensors

Product description

The lcs-sensor with one analogue output

measures the distance to an object within

the detection zone contactless. A signal pro-

portional to distance is created  according to

the adjusted window margings of the ana-

logue characteristic curve.

The sensor automatically detects the

load put to the analogue output and

switches to current output or voltage

output respectively.

Choosing between rising and falling

output characteristic is possible. 

Light emitting diodes (three-colour

LEDs) indicate the operation conditions.

The sensors can be trained using Teach-

in processes.

Using the LinkControl adapter (optional

accessory) all sensor parameter settings

may be made by a Windows-Software.

Important instructions for assembly and

application

All employee and plant safety-relevant

measures must be taken prior to assembly,

start-up, or maintenance work (see operation

manual for the entire plant and the operator

instruction of the plant).

The sensors are not considered as safety
equipment and may not be used to ensure
human or machine safety!

The lcs-sensors indicate a 

blind zone

, in

which the distance cannot be measured. The

operating range

 indicates the distance of the

sensor that can be applied with normal re-

flectors with sufficient function reserve.

When using good reflectors, such as a calm

water surface, the sensor can also be used up

to its  

maximum range

. Objects that strongly

absorb (e.g. plastic foam) or diffusely reflect

sound (e.g. pebble stones) can also reduce

the defined operating range.

Assembly instructions

Assemble the sensor at the installation

location.

Plug in the connector cable to the M 12

connector.

The assembly distances shown in Fig.2 for

two or more sensors should not be fallen

Start-up

lcs-sensors are delivered factory made with

the following settings:

Rising analogue characteristic

Window margins for the analogue out-

put set to blind zone and operating

range

Measurement range set to maximum

range

Set the parameters of the sensor using the

Teach-in procedure.

>30 cm

>1,0 m
>1,7 m

>60 cm

>5,4 m

Operation

lcs- sensors work maintenance free. Small

amounts of dirt on the surface do not influ-

ence function. Thick layers of dirt and caked-

on dirt affect sensor function and therefore

must be removed.

Note

lcs-sensors have internal temperature

compensation. Because the sensors heat

up on their own, the temperature com-

pensation reaches its optimum working

point after approx. 30 minutes of opera-

tion.

If an object is within the set window

margins of the analogue output, then

LED D1 lights up green, if the object is

outside the  window margins, then LED

D1 lights up red.

The load put to the analogue output is

detected automatically when turning

supply voltage on.

If the signal at the Com line does not

change for 20 seconds during parameter

setting mode the made changes are sto-

red and the sensor returns to normal

mode operation.

You can reset the factory settings at any

time, see »Lock Teach-in & factory set-

ting«

.

lcs-sensors optional can be programmed

using the LinkControl adapter LCA-2,

see «Optional setting of parameters

using the LinkControl Adapter LCA-2».
