  • Page 4: System Description

    1 System description 1 .1 Intended use The device is an electronic level transmitter / level switch for monitoring, control as well as continuous measurement of filling levels in liquids, pastes and coarse bulk materials. Additional application fields are volume or flow measurement. The operational reliability of the device is ensured only at the intended use.

  • Page 5: Function

    1 .4 Function 1 .4 .1 Measuring principle The transducer of the ultrasonic sensor transmits ultrasonic pulses to the product surface. These pulses are reflected by product surface and received back by the transducer as echoes. The running time of the ultrasonic pulses from emission to reception is proportional to the distance and hence the level.

  • Page 6: Safety Notes

    2 Safety notes 2 .1 Operational safety The device is safely built and tested according to state-of-the-art technology and has left the factory in perfect condition as regards technical safety. The device meets the legal requirements of all relevant EU directives. This is confirmed by attaching the CE mark.

  • Page 7: Installation

    Installation The correct function of the device within the specific technical data can only be guaranteed, if the permitted process and environmental temperatures (see chapter „Technical data“) will not be exceeded. 3 .1 Installation place 3 .1 .1 Level measurement • Do not install the sensor in the middle of the tank (C).
  • Page 8 3 .1 .2 Installation in narrow shafts • In narrow shafts with strong interference echoes, we recommend using a stand pipe resp. an ultrasound guide pipe (e.g. PE or PVC wastewater pipe) with a minimum diameter of 100mm. • Make sure that the pipe is not soiled by accumulated dirt. If necessary, clean the pipe at regular intervals.

  • Page 9: Installation Notes

    3 .2 Installation notes • Drive the system pressure free prior installation resp. deinstallation of the sensor. • The screw-in of the thread process connection by using the terminal enclosure, the connection plug resp. the connection cable is not permitted. • The tightening of the thread process connection may only be done at the hexagon by a suitable spanner and with the maximum permitted torque strength (see chapter „Technical data“).
  • Page 10 3 .2 .5 Nozzle installation Use a pipe nozzle if you cannot maintain the blocking distance in any other way. • The interior of the nozzle must be smooth and may not contain any edges or welded joints. In particular, there should be no burr on the inside of the tank side nozzle end. • To minimize disturbing factors, we recommend an angled socket edge (ideally 45°).

  • Page 11: Electrical Connection

    Electrical connection The electrical connection of the device must be carried out according to the respective country specific standards. Incorrect installation or adjustment could cause applicationally conditioned risks. Warning! The instrument may only be installed if the supply voltage is switched off. 4 .1 Potential equalization - earthing The device must be grounded.

  • Page 19 5 .5 .1 .2 Switch Point / Reset Switch Point The input values refers to the set display value or acc. to display scaling. The reset switch point must be lower or equal to the switch point. At inverse measuring principle, e.g. distance measurement, the reset switch point must be greater or equal to the switch point.
  • Page 20 Operating Mode outside • The switch output is activated, if the current measuring value is outside the area that is defined by the switch point and the reset switch point and if the set switch point delay time has been expired. The switch output is deactivated, if the current measuring value is inside the area that is defined by the switch point and the reset switch point and if the set reset switch point delay time has been expired.
  • Page 21 5 .5 .1 .4 .5 Pump function runtime S1/S2/S3/S4 Pump function runtime is used to control several pumps with the same function dependent on the previous running time. Always the pump with the shortest running time is switched on and the pump with the longest running time switched off.
  • Page 22 5 .5 .1 .4 .6 Pump function sequential S1/S2/S3/S4 Purpose of the pump function sequential is the alternating use of multiple pumps for the same task (Overflow protection or dry running protection). Due using the pumps for the same task, it can be detected by the pump switch-on time, if one of the pumps doesn’t operate with the necessary performance (Runtime of the pump increases).
  • Page 23 5 .5 .1 .6 Forced switchover – E This menu item is only available at function principle pump function runtime resp. pump function sequential. The purpose of the forced switchover is the change of a pump after a predefined dime. This gets relevant, if the measuring value does not change for a longer time and thus always the same pump is switched-on.
