Product description

The crm+sensor with one analogue out-

put and one switched output measures

the distance to an object within the de-

tection zone contactless. A signal propor-

tional to distance is created and the

switched output is set according to the

adjusted detect distance.

The ultrasonic transducer surface of the

crm+sensors is laminated with a PEEK

film. The transducer itself is sealed

against the housing by a PTFE joint ring.

This composition ensures a high resitance

against many aggressive substances.

The sensor automatically detects the load

put to the analogue output and switches

to current output or voltage output re-

spectively.

All settings are done with two push-but-

tons and a three-digit LED-display

(TouchControl).

Light emitting diodes (three-colour LEDs)

indicate all operation conditions.

Choosing between rising and falling out-

put characteristic as well as output func-

tion NOC and NCC is possible.

The sensors are adjustable manually using

the numerical LED-display or may be trai-

ned using Teach-in processes.

Useful additional functions are set in the

Add-on-menu.

Using the LinkControl adapter (optional

accessory) all TouchControl and additio-

nal sensor parameter settings may be

made by a Windows-Software.

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.

The crm+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.

Synchronisation

If the assembly distances shown in Fig.1 for

two or more sensors are exceeded the inte-

grated synchronisation should be used. Con-

nect Sync/Com-channels (pin 5 at the units re-

ceptable) of all sensors (10 maximum).

chronisation/multiplex

Multiplex mode

The Add-on-menu allows to assign an indivi-

dual address »01« to »10« to each sensor

connected via the Sync/Com-channel (Pin5).

The sensors perform the ultrasonic measure-

ment sequentially from low to high address.

Therefore any influence between the sensors

is rejected.

The address »00« is reserved to synchronisa-

tion mode and deactivates the multiplex

mode. (To use synchronised mode all sensors

cation.

Plug in the connector cable to the M 12

connector.

Operation

crm+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

As a result of the design the assembly of

PEEK film and PTFE joint ring is not gas-

proof.

The chemical resistance has to be tested

experimentally if necessary.

crm+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 mar-

gins of the analogue output, then LED D1

lights up green, if the object is outsite the

window margins, then LED D1 lights up

red.

The load put to the analogue output is

detected automatically when turning

supply voltage on.

During normal mode operation, a yellow

LED D2 signals that the switched output

has connected.

During normal mode operation, the mea-

sured distance value is displayed on the

LED-indicator in mm (up to 999 mm) or

cm (from 100 cm). Scale switches auto-

matically and is indicated by a point on

top of the digits. Alternatively a percent-

age scale may be set in the add-on menu.

In this connection 0% and 100% corre-

spond to the set window margins of the

analogue output.

In the »Two-way reflective barrier« ope-

rating mode, the object has to be within

the range of 0-85 % of the set distance.

During Teach-in mode, the hysteresis

loops are set back to factory settings.

If no objects are placed within the detec-

tion zone the LED-indicator shows »- - -«.

Show parameters

Tapping push-button T1 shortly during nor-

mal mode operation shows »PAr« on the

LED-display. Each time you tap push-button

T1 the actual settings of the analogue output

and the switched output are shown.

Detection zones

for different objects:

The dark grey areas are determind

with a thin round bar (10 or 27 mm dia.)

and indicate the typical operating range

of a sensor. In order to obtain the light grey

areas, a plate (500 x 500 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.
