  • Page 5: Basic Description

    The sensor can be set by applying a magnetic pen to sensitive surfaces, or by means of a program- ming wire (variant RFLS-28 _-_-_- PD -_- MW). For sensors with the possibility of remote param- eterization, only basic settings (resolution of two interfaces) can be performed. A special evaluation unit SSU-1212-AD must be used for remote parameterization of the sensor.

  • Page 7: Installation And Putting Into Operation

    A sensor with PNP output can be loaded only by resistive or inductive load. The capacitative loads and low resistance loads (bulb) are evaluated by the sensor as a short circuit. Connection diagrams are listed in Figure below. The RFLS-28 sensors are connected to evaluation units permanently by a PVC cable. Legend: BK – black BN –...

  • Page 8: Settings

    The settings must be made before installing the sensor in the TN-28 tubular extender.. When setting up the RFLS-28 sensor, it is necessary to monitor the signalling of both LEDs, there- fore it is necessary to make settings before installing the sensor in the tank.

  • Page 15: Setting Elements

    7. Setting elements The RFLS-28 switch can be set in two ways, namely using the magnetic pen M (variants RFLS-28_- _-_-P-_-M, RFLS-28_-_-_-PD-_-M a RFLS-28_-_-_-PD-_-MW) or the programming wire W (vari- ant RFLS-28_-_-_-PD_MW). Remote parametrization only allows basic settings (interface of two media).

  • Page 16: Function And Status Indication

    • If the sensor is set up, you will proceed to its installation in the TN-28 extension tube. • First, the cable is passed through the extension tube and then the RFLS-28 sensor is screwed into the pipe. • The complete assembly with the selected process connection is attached to the tank.
