Product description

 The crm+sensor with one analogue out-

put measures the distance to an object
within the detection zone contactless. A
signal proportional to distance is created
according to the adjusted window
margings of the analogue characteristic
curve.

 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 re­spectively.

 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 is possible.

 The sensors are adjustable manually using

the numerical LED-display or may be trai­ned using Teach-in processes.

 Useful additional functions are set in the

Add-on-menu.

 Using the LinkControl adapter (optional

accessory) all TouchControl and additio­nal 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 re­flectors 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 inte­grated synchronisation should be used. Con­nect Sync/Com-channels (pin 5 at the units re­ceptable) of all sensors (10 maximum).

chronisation/multiplex

Multiplex mode

The Add-on-menu allows to assign an indivi­dual address »01« to »10« to each sensor
connected via the Sync/Com-channel (Pin5).
The sensors perform the ultrasonic measure­ment sequentially from low to high address.
Therefore any influence between the sensors
is rejected.
The address »00« is reserved to synchronisa­tion mode and deactivates the multiplex

Operation

crm+sensors work maintenance free. Small
amounts of dirt on the surface do not influ­ence function. Thick layers of dirt and caked­on 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 gas­proof.

 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 com­pensation reaches its optimum working
point after approx. 30 minutes of opera­tion.

 If an object is within the set window mar-

gins 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.

 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 auto­matically and is indicated by a point on
top of the digits. Alternatively a percent­age scale may be set in the add-on menu.
In this connection 0% and 100% corre­spond to the set window margins of the
analogue output.

 If no objects are placed within the detec-

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

 If no push-buttons are pressed for 20 se-

conds during parameter setting mode the
made changes are stored and the sensor
returns to normal mode operation.

Show parameters

Tapping push-button T1 shortly during nor­mal mode operation shows »PAr« on the
LED-display. Each time you tap push-button
T1 the actual settings of the analogue output
are shown.
