Microsonic crm plus 25/DIU/TC/E Operating Manual

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.
Operating manual
All settings are done with two push-but-
crm+ Ultrasonic Sensors with
tons
one analogue output and one
(TouchControl).
Light emitting diodes (three-colour LEDs)

Safety Notes

Read the operating instructions prior to

start-up.

Connection, installation and adjustment

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-
and a three-digit LED-display
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).

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

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.
