Product description

• The crm+ sensor with one analogue output measures the distance to an object within the detection zone contactless. A signal proportional to distance is created  according to the adjusted window limits 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 resistance against many aggressive substances.
• All settings are done with two pushbuttons and a three-digit LED display (TouchControl).
• Three-colour LEDs indicate all operation conditions.
• Choosing between rising and falling output characteristic is possible.
• The sensors are adjustable manually via TouchControl or via Teach-in procedure.
• Useful additional functions are set in the Add-on menu.
• Using the LinkControl adapter (optional accessory) and the LinkControl software for Windows®, all Teach-in and additional sensor parameter settings can be optionally undertaken.
  The crm+ sensors have a blind zone in which distance measurement is not possible. 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.

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, use in the area of personal and machine protection not permitted

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 mode.
To use synchronised mode all sensors must be set to address »00«.

Installation

• Assemble the sensor at the installation location.
• Plug in the connector cable to the M12 connector, see Fig. 2.

Start-up

• Connect the power supply.
• Set the parameters of the sensor manually via TouchControl (see Fig. 3 and Diagram 1)
• or use the Teach-in procedure to adjust the detect points (see Diagram 2).

Factory setting
crm+ sensors are delivered factory made with the following settings:

• Rising analogue characteristic
• Window limits for the analogue output set to blind zone and operating range
• Measurement range set to maximum range

Maintenance

crm+ sensors work maintenance free.
Small amounts of dirt on the surface do not influence function. Thick layers of dirt and caked-on dirt affect sensor function and therefore must be removed.

Notes

• 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 compensation reaches its optimum working point  after approx. 30 minutes of operation.
• If an object is within the set window limits of the analogue output, then LED D1 lights up green, if the object is outside the window limits, 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 measured distance value is dis- played 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 limits of the analogue output.
• If no objects are placed within the detection zone the LED-indicator shows »— — —«.
• The sensor can be set to its factory setting, see Diagram 3.
• If no push-buttons are pressed for 20 seconds during parameter set- ting mode the made changes are stored and the sensor returns to normal operating mode.

Show parameters

• In normal operating mode shortly push T1. The LED display shows »PAr.«

Each time you tap push-button T1 the actual settings of the analogue output re shown.

Note
Changes in the Add-on menu may impair the sensor function.
A6, A7, A8, A10, A11, A12 have influence on the response time of the sensor.

Technical data

• blind zone
• operating range
• maximum range
• angle of beam spread
• transducer frequency
• resolution

detection zones
for different objects:
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 very large reflector – for instance a plate – can still be recognised.
The requirement here is for an optimum alignment to the sensor.
It is not possible to evaluate ultrasonic reflections outside this area.
