Sensor 4 negative (bl) Note: • The scope of supply for the CUM 750 / CUS 70 measuring system includes 6m of cable. If a cable extension between the transmitter and sensor is required, use a screened cable. • The distance between sensor and transmitter must be no more than 100m. - Page 15 Electrical connection CUM 750 / CUS 70 4.3.3 Connecting the analogue output and serial ports The measuring system is designed for up to four 4-20mA analogue outputs, one per sensor. The connection uses a 14-pin PHOENIX plug-connector, which also contains the pins for the RS 485 and RS 232 serial ports.
- Page 16 CUM 750 / CUS 70 Electrical connection 4.3.4 Switch contacts connection The measuring system is designed to control up to four relays. Connection is by means of two 6-pin PHOENIX plug-in connectors (for two relays). Connecting the X3 terminal block Pin No.

Operation CUM 750 / CUS 70 Operation 6.1 Key assignment The instrument is operated using the keypad on the front or using a PC connected to the serial interface. In local operating mode, you can move through the menu using the arrow keys '↓ ↓ ↓ ↓ ‘ and '↑ ↑ ↑ ↑ ‘. Select the required option by pressing 'E’. - Page 20 CUM 750 / CUS 70 Operation 6.2.1 DIGITAL display mode In this display mode, you can view the distance between the sensor position and the separation zone (measuring mode = FROM SURFACE) or the distance between basin bottom and the separation zone (measuring mode = FROM BOTTOM) displayed numerically using a selected unit (m, cm, ft, in, yd).
- Page 21 Operation CUM 750 / CUS 70 6.2.2 GRAPHIC display mode This display mode shows the strength of the feedback signal inside the basin. This type of display is useful when the system is installed for the first time to view the material stratification in the basin.

Page 22: Menu Structure
CUM 750 / CUS 70 Operation 6.3 Menu structure The menu for setting parameters is split into two levels: ADVANCED OFF and ADVANCED ON. ADVANCED OFF allows access to the parameters required to adapt the system to the application. ADVANCED ON allows access to all parameters. This is only necessary for servicing. The pa- rameters in the ADVANCED ON menu are only accessible by entering a code number. - Page 23 Operation CUM 750 / CUS 70 Menu structure SYSTEM SETUP Measure LEVEL / RANGE Units [m], [cm], [in], [ft], [yd] Recall / Save FACTORY PRESET / USER No. of points MODIFY POINTS Tank config Tank depth [m], [cm], [in], [ft], [yd]...

Zero point Scraper Tank depth: Set the tank depth for each sensor position. To obtain the correct display of the sludge level, it is important to enter the exact tank depth.
- Page 27 Operation CUM 750 / CUS 70 6.6.2 ACOUSTICS submenu You can enter the specific data for the ultrasonic signal gain using the ACOUSTICS submenu. Gain start: Set the entire gain for the system by choosing the GAIN START command. From a functional aspect, these parameters are equivalent to a volume control.
- Page 28 CUM 750 / CUS 70 Operation Gain increment: Set the gain increments of the measuring signal between each screen refresh, e.g. Gain 20 + 0.5. Enable the automatic gain "Auto gain" function first. Setting range: 0.5 ... 5.0 steps Clip count: Set the number of pixels which the 75% display height can exceed before the gain is scaled back, e.g.
- Page 29 Operation CUM 750 / CUS 70 Threshold: The THRESHOLD creates the primary condition for the measuring system for tracking the separation zones based on the selected algorithm. The system searches for a point (on the graphic display) where the signal strength has at least a "threshold value percentage" of the strongest signal (100% of the display height).

The function is dependent on the measuring mode set. If you select the "LEVEL" measuring mode, the 20mA setting should lie within the min. and Max.
- Page 32 CUM 750 / CUS 70 Operation Setpoint: Set the switch point of the relay. Setting range: 0 ... 100m Dead band: Set the value at which the relay status should be maintained until the measured variable has changed by the hysteresis value.
