    The power supply must be designed as a stabilised source of low safe voltage with galvanic isolation. If a switched power supply is used, its design must effectively suppress common mode interference. If the switched power supply is equipped with a PE protective terminal, it must be strictly earthed!

    For safety reasons, for scanning min. level, we recommend setting “O-mode” (sensor closes when submerged). A faulty sensor or wiring will take effect here in the same way as level emergency conditions by opening the sensor. Analogously, for the max. level, we recommend setting “C-mode” (sensor opens when submerged). © Dinel, s.r.o. RFLS–28...

    Unless otherwise agreed, “O-mode” is set on all sensors straight from the factory. When using the “quick settings” function, the sensor does not eliminate the presence of deposits and foam on the electrode. The manufacturer recommends performing the basic settings as soon as possible. © Dinel, s.r.o. RFLS–28...
