2 Basic safety instructions
2.1 Requirements for personnel
• Installation, commissioning, operation and maintenance of the measuring system may be
carried out only by specially trained technical personnel.
• The technical personnel must be authorized by the plant operator to carry out the specified
activities.
• The electrical connection may be performed only by an electrical technician.
• The technical personnel must have read and understood these Operating Instructions and

Product descriptionTurbimax CUS71D
3 Product description
3.1 Product design
The sensor is designed for continuous in-situ determination of interfaces.
The sensor includes all necessary modules:
• Power supply
• The ultrasonic source emits the measurement signals.
• The ultrasonic receiver receives the measurement signals, digitalizes the signals and
converts them to a measurement value.
• The sensor microcontroller controls the internal operations and data transmission.
The preconfigured sensor can be used at a measuring point.
3.1.1 Measuring principle
A piezoelectric crystal is enclosed in a flat cylindrical plastic housing. When the crystal is
excited by an electrical voltage, it generates a sonar signal. This causes ultrasonic waves to be
transmitted at a frequency of approx. 650 kHz and at an angle of 6° to scan the separation
zones.
The measured variable is the time the transmitted ultrasonic signal needs to reach the solid
particles in the separation zone and return to the receiver. The separation zone is computed
after the maximum slope and the maximum signal amplitude.
A sensor version featuring a wiper is available to reliably avoid the buildup of deposit on the
sensor membrane.

Installation instructions
Find a suitable installation position for the sensor in the basin. Take the following points into
consideration when selecting the installation position:
1.Ensure the distance from the basin rim is at least 50 cm (1.64 ft) (the sensor emits
ultrasonic waves in a conical pattern).
There should not be any conduits or basin wall protrusions in the measuring range
below the sensor. Scraper units that are only temporarily in this area are permitted.

7.1 Preparatory steps
7.1.1 Factory settings
The sensor is preconfigured on leaving the factory. Once the installation parameters have
been adjusted, the sensor is ready for use in a wide range of applications without further
adjustments. The factory settings cannot be deleted and can be restored at any time.
Enter the installation parameters at the Liquiline CM44x transmitter.
‣
For more information, please refer to the Operating Instructions of the transmitter.
8 Operation
8.1 Sensor monitoring
The acoustic signals are continuously monitored and analyzed for plausibility. If
inconsistencies occur, an error message is output via the transmitter.
In addition, the following fault conditions are detected by the sensor diagnostics of Liquiline
CM44x:
• Implausibly high or low measured values
• Disturbed regulation due to incorrect measured values
20Endress+Hauser
Turbimax CUS71DDiagnostics and troubleshooting
8.2 Cyclic cleaning
Cyclic cleaning is available for ultrasonic sensors with an integrated wiper. The wiper interval
is set to 240 minutes at the factory.
8.3 Automatic wiper function
Sensor versions with a wiper have an integrated automatic wiper function. The wiper starts as
soon as the sensor stops receiving a signal. This happens when the sensor membrane is
fouled, for example.
• The wiper wipes twice every 5 minutes for a maximum of 3 runs.
• If the sensor does not receive a signal after 30 minutes, the sensor triggers the diagnostic
message 172 Echo loss at the transmitter.
9 Diagnostics and troubleshooting
9.1 General troubleshooting
When troubleshooting, the entire measuring point must be taken into account:
• Transmitter
• Electrical connections and cables
• Assembly

MaintenanceTurbimax CUS71D
10 Maintenance
You must perform maintenance tasks at regular intervals.
‣
We recommend setting the maintenance times in advance in an operations journal or log.
The maintenance cycle primarily depends on the following:
• The system
• The installation conditions
• The medium in which measurement takes place
CAUTION
L
Risk of injury from acids or medium, damage to clothing and equipment!
Switch off the cleaning unit before removing the sensor from the medium.
‣
Wear protective goggles and safety gloves.
‣
Clean away splashes on clothes and other objects.
‣
10.1 Maintenance tasks
10.1.1 Cleaning the sensor
Sensor without wiper
Sensor fouling can affect the measurement results and even cause a malfunction.
Clean the sensor, and the underside of the sensor in particular, at regular intervals to
‣
ensure reliable measurement.
The frequency and intensity of the cleaning process depend on the medium.
Clean the sensor:
• As specified in the maintenance schedule
• Before returning it for repair
After cleaning, rinse the sensor with copious amounts of water.
‣
Sensor with wiper
The wiping interval is preselected via the software. The cleaning interval depends on the
medium.
We recommend you replace the wiper blade every 6 to 12 months.
