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.

 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.

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.

The lcs+ sensors are IO-Link-capable
in accordance with IO-Link specifica­tion V1.0.

Pointer

 In IO-Link mode LinkControl is not

available.

Process data

The lcs+ cyclically transmits the mea­sured distance value with a resoluti­on of 1 mm and the logical state of
the switched output.

Service data

The following sensor parameters
may be set via IO-Link interface using
the IO-Link device description (IODD).

Detect point 1

The switched output is activated

when the distance to an object is
smaller than the present detect point.

Return detect point 1

The switched output is reactivated
when the distance to an object is
greater than the present return de­tect point (detect point + hysteresis).

Pointer

 The return detect point 1 must al-

ways be greater than the detect
point 1.

Detect point 2, return detect point 2
By programming these two detect
distances to a value smaller than the
actual maximum distance the win­dow mode is activated. The window
lies between detect point 1 and de­tect point 2.

Pointer

 The return detect point 2 must al-

ways be smaller than the detect
point 2.

Foreground suppression

Spurious reflections, caused by ob­jects in the foreground of the sensor
may be blocked out by the fore­ground suppression.

Pointer

 The object in the foreground can

cause multiple reflections that lead
to invalid measurement.

 The object in the foreground must

not cover the sensor in a way that
the detection zone is influenced.

Maximum range

The value specifies the maximum
measurement range.

Teach-in via push-buttons T1/T2

The push-buttons can be locked/un­locked for the Teach-in procedures.

Set NOC/NCC

The NCC or NOC output function can
be present for the switched output.

Measurement filter

lcs+ ultrasonic sensors provide for a
choice of 5 filter settings:

 F00 (no filter)

Each ultrasonic measurement acts in
an unfiltered manner on the output.

 F01 (standard filter)

On the object continuously ap­proaching the sensor, the ongoing
interval is immediately taken on
and the output correspondingly
activated. The effect of the object
abruptly moving away from the
sensor is for the existing distance
to be saved for a retaining time
dependent on the filter strength
and for the switched output state
to be maintained.

 F02 (Average value filter)

Forms the arithmetic mean across
a number of measurements. The
output is activated in keeping with
the average value. The number of
measurements, from which the
average value is formed, depends
on the selected filter strength.

 F03 (

foreground filter

)
This filter reacts very fast on sensor
close measurement values and gi­ves a straightened output on this
sensor close level. Disturbances
from objects in the background or
momentary loss of echoes from
the object to be detected are filte­red out.

 F04 (

background filter

)
This filter reacts very fast on sensor
far measurement values and gives
a straightened output on this sen­sor far level. Disturbances from
obstacles in front of the object to
be detected are filtered out.

Filter strength

A filter strength between 0 – weak
filter effect – and 9 – pronounced fil­ter effect – can be selected for each
measurement filter.

Temperature compensation

The temperature compensation im­proves the measurement accuracy at
changing ambient temperature and
may be deactivated.

Pointer

 The measurement accuracy

amounts to 0,17 %/K change of
temperature without compensa­tion.

Switch-on delay

If the switch-on delay is activated,
the switched output will not be set
before the programmed time once
the measurement value falls below
the set detect point. If the measure­ment value increases to the detect
point again, the switched output will
be reset after 50 % of the program­med on-delay time.

Detection zone sensitivity

The size of the detection zone can be
varied in three steps.

Synchronisation and multiplex in
IO-Link mode

As in SIO mode up to 10 sensors can
be synchronised by interconnecting
the sync-channel (Pin 5) of each sen­sor. Additionally the multiplex mode
is available.

Multiplex mode device address

In multiplex mode for every sensor
connected via the sync-channel a
unique device address has to be set.
The sensors then perform there
measurement in increasing order of
the device addresses. With multiplex
address »0« the sensors work syn­chronous, with address »11« syn­chronisation/multiplex is disabled.

Pointer

 In multiplex mode the response

time of each sensor extends corre­sponding to the number of con­nected sensors.

Multiplex mode highest address

To optimise the multiplex speed the
highest assigned device address may
be set instead of the default value
»10«.

Interference noise suppression

This filter keeps the state of the out­put for the time a ultrasonic interfe­rence noise, e.g. leaking compressed
air, makes a measurement impossib­le.

Pointer

 The Interference noise suppression

filter extends the measurement cy­cle of the sensor and for this it's
response time.

Echo quality

To simplify the adjustment of the
sensor towards the measurement ob­ject the echo quality can be obser­ved. The value gives back the
strength of the reflected echo.

System commands

With 6 system commands the follo­wing settings may be carried out:

 Teach-in detect point.
 Teach-in detect point +8 %.
 Teach-in window mode detect

point 1.

 Teach-in window mode detect

point 2.

 Teach-in two way reflective barrier.
 Reset sensor to factory settings.
