196 SetupVEGAWAVE 61 • - NAMUR32249-EN-140625The characteristics reversal can be carried out with the DIL switch.You can choose between falling characteristic curve (switch positionmax.) and rising characteristic curve (switch position min.). This al-lows you to output the desired current.Modes• min. - rising characteristic curve (High current when immersed)• max. - falling characteristics (Low current when immersed)The NAMUR output can be switched over to falling or rising charac-teristics (see also "Function chart").The simulation key is located in a recess on the upper side of theelectronics module. Push the simulation key with a suitable object(screwdriver, pen, etc.).When the key is pushed, a line break between sensor and process-ing unit is simulated. The signal lamp on the sensor extinguishes. Themeasuring system must signal a fault and take on a safe state whenthe key is pushed.Keep in mind that downstream connected instruments will be acti-vated during operation. This allows you to check the correct functionof the measuring system.Control lamp (LED) for indication of the switching condition• yellow = High current ≥ 2.4 mA• dark = Low current ≤ 1 mA• yellow (flashing) = Failure ≤ 1 mA6.3 Function chartLevel switch VEGAWAVE 61The following chart provides an overview of the switching conditionsdepending on the set mode and the level.Note:The mode setting on the NAMUR amplifier must be selected in sucha way that the switching output takes on safe state in case of failure (I≤ 1 mA).Level Signal current -SensorControl lampFalling character-istics max.≥ 2.4 mAFalling character-istics max.≤ 1 mACharacteristics reversal(2)Simulation key (3)Signal lamp (6)
