Product description Turbimax 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.

7 Commissioning

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
20 Endress+Hauser
Turbimax CUS71D Diagnostics 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
• Sensor
The possible causes of error in the following table refer primarily to the sensor.
Display
No display, no sensor reaction
Display value too high or too low
Display value fluctuating greatly
Pay attention to the troubleshooting information in the Operating Instructions for the transmitter. Check the transmitter if necessary.
Check Solution
• Mains voltage connected to the transmitter
• Sensor connected correctly
• Deposit buildup on sensor membrane
• Check sensor/channel configuration
• Basin configuration
• Check sensor installation
• Check mounting location
• Deposit buildup on sensor membrane
• Basin configuration
• Apply line voltage
• Make the right connection
• Clean sensor
• Assign sensor
Configure sensor
• Select a different mounting location
• Clean sensor
• Configure sensor
Maintenance Turbimax 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.
