level state
For safety reasons, we recommend using the setting of the mode "O" for min. level sensing (the sensor is closed upon immersion). It is for failure safety reasons –
eventual failure of sensor behaves similarly as an exceeding of the limit state. Analogically, for the max. level it is recommended to set the mode "C" (the sensor is open
upon immersion).

protections
The level sensor is equipped with protection against electric shock on the electrode, reverse polarity, output current overload, short
circuit and against current overload on output.
Protection against dangerous contact is provided by low safety voltage according to ČSN 33 2000-4-41. Electromagnetic compat-
ibility is provided by conformity with standards EN 55022/B, EN 61326-1,EN 61000-4-2, -3 ,-4, -5 and 6.
