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 evaluation limits
The ultrasonic sensor features an analogue output with two teachable evaluation limits. These are set by applying the supply voltage -U
or +UB to the TEACH-IN input.
B
The supply voltage must be applied to the TEACH-IN input for at least 1 s. The lower
evaluation limit A1 is taught with -U
, A2 with +UB.
B
Two different output modes can be set:
1. Analogue value increases with rising distance to object (rising ramp)
2. Analogue value falls with rising distance to object (falling ramp)
TEACH-IN rising ramp (A2 > A1)
- Position object at lower evaluation limit
- TEACH-IN lower limit A1 with - U
B
- Position object at upper evaluation limit
- TEACH-IN upper limit A2 with + U
B
TEACH-IN falling ramp (A1 > A2):
- Position object at lower evaluation limit
- TEACH-IN lower limit A2 with + U
B
- Position object at upper evaluation limit
- TEACH-IN upper limit A1 with - U
