Description

Functional description

The enclosure and transducer of this ultrasonic sensor
form a hermetically sealed unit. Due to its special
design, this sensor is EHEDG compliant, and together
with an appropriate fixture are especially suitable for
applications where there are increased hygiene
requirements, such as in the manufacture and handling
of food.
For reliable operation, due to the special design of this
sensor, solely the enclosed mounting accessories must
be used, even in applications without special hygiene
requirements.

Installation

Cleaning the Sensor in Areas with Hygiene Requirements

The sensor may only be used with the mounting aid included in the scope of delivery
as the fixture. Please note the information in the enclosed package insert for the
mounting aid with regard to the correct position of the seals and the correct process
for tightening the screw connections.

If the sensor as a whole is located in an area subject to hygiene requirements, the
sensor must be accessible from all sides for cleaning purposes. If the sensor is fitted
with only the front in an area subject to hygiene requirements, the front must be ac­cessible from all sides accordingly.

The sensor and corresponding fixture are certified by ECOLAB. The components
were subjected to the cleaning agents listed in the certificate and are resistant to the­se agents. Use of other cleaning agents and chemicals is also possible. However, to
ensure the sensor and fixture offer resistance to these substances, corresponding
tests must be performed by the user.

For cleaning purposes, as a general rule you can completely cover the sensor inclu­ding the fixture with foam and clean using a water jet. Cleaning at elevated tempera­tures of up to 85 °C is possible. It is not permitted to use high-pressure cleaning
equipment for cleaning purposes in areas subject to hygiene requirements.

Due to the unique design of this sensor, only the mounting accessories included with the sen­sor must be used in order to ensure reliable operation, even in applications without specific hy­giene requirements.

Adjusting the switch points

The ultrasonic sensor features a switching output with two teachable switch points.
These are set by applying the supply voltage -U

or +UB to the TEACH-IN input. The

B

supply voltage must be applied to the TEACH-IN input for at least 1 s. switch point A1
is taught with -U

, A2 with +UB.

B

Five different output functions can be set

1. Window mode, normally-open function

2. Window mode, normally-closed function

3. one switch point, normally-open function

4. one switch point, normally-closed function

5. Detection of object presence

TEACH-IN window mode, normally-open function

- Set target to near switch point

- TEACH-IN switch point A1 with -U

B

- Set target to far switch point

- TEACH-IN switch point A2 with +U

B

TEACH-IN window mode, normally-closed function

- Set target to near switch point

- TEACH-IN switch point A2 with +U

B

- Set target to far switch point

- TEACH-IN switch point A1 with -U

B

TEACH-IN switch point, normally-open function

- Set target to near switch point

- TEACH-IN switch point A2 with +U

B

- Cover sensor with hand or remove all objects from sensing range
