Page 13: Device Description
Turbimax CUS71D Device description Device description Sensor design The sensor is designed for continuous in-situ determination of interfaces. The sensor includes all necessary modules: • Power supply • Ultrasonic source sends the measurement signals. • Ultrasonic receiver receives the measurement signals, digitalizes and converts the signals to a measurement value. -
Page 14: Calibration
Device description Turbimax CUS71D Calibration 5.5.1 Factory calibration The sensor is precalibrated when leaving the factory. After adaption of the basin parameters, the sensor can be used in a wide range of applications without additional calibration. The factory calibration cannot be deleted and can be retrieved at any time. All other calibrations - performed as customized calibrations - are referenced to this factory calibration. -
Page 15: Commissioning
Commissioning Commissioning Firmware update Turbimax CUS71D needs a firmware version "01.02.02-0048" or later. Your current firmware version can be found at: Menu/Diagnostics/System information/Software version If your controller is equipped with an older firmware version you have to perform a firmware update. -
Page 16: Basic Settings
Commissioning Turbimax CUS71D Basic settings After switching on the controller you have to perform some settings to get correct measurement Path: Menu/Setup/Inputs/UIS/Tank configuration The menu Tank configuration defines tank depth and zero adjust. The quality of the measuring results depends on the accuracy of these inputs. - Page 17 Turbimax CUS71D Commissioning Enter the Zero adjust (distance from the waterline to the sensor diaphragm) Outside the Blanking zone (above Upper window limit and below Lower window limit) the permanent echo signals are blanked as interference signals. For upper and lower window limit enter the distance to the waterline.
- Page 18 Commissioning Turbimax CUS71D Path: Menu/Setup/Inputs/UIS/Sensor signal The parameters in the menu Sensor signal are factory preset. If measurement failures are observed the parameters can be adjusted. Acoustic control • Automatic Automatic amplification control • Manual Manual amplification control In automatic mode you cannot modify the parameter Current gain.
- Page 19 Turbimax CUS71D Commissioning The Refresh rate determines the time span to update the current measurement. You can select 2, 4, 6, or 8 seconds. Damping This parameter establishes the number of updates that are averaged to determine the current measurement. It is used to remove the effects of random fluctuations caused by settling or disturbed material.
- Page 20 Commissioning Turbimax CUS71D You can change the parameters of the Tank zone. Gain band establishes the maximum amount that Current gain (with Automatic ON) can vary once the initial gain level has been established. Enter a value from 5 to 30.
- Page 21 Turbimax CUS71D Commissioning Range above bottom establishes a zone near the bottom of tank that permits special handling of a dominant signal that originates from the tank floor. This signal will be suppressed for the calculation of the measuring value.
- Page 22 Commissioning Turbimax CUS71D Around the interface you can define a window entering a distance above and below the interface. The signal that is inside the window is given preferential consideration. You can enter a distance from 0.0 to 10.0 m.
- Page 23 Turbimax CUS71D Commissioning Alarm delay echo loss establishes the amount of time that the sensor must experience a loss of echo before initiating the echo loss action. You can enter a time from 0 to 255 minutes. Reboot track performs a new initialization of the sensor.
