...and PROGRAMMING
The measuring values and output signals can be adjusted with the turning of a programming ring - this is also possible whilst wearing work gloves.

Display fig. 6 The programming ring at the sensor head can be turned to Pos. 1 and 2. It can be removed as a key, or reverse mounted (turned by 180°) in order to prevent unintentional programming by turning the programming ring.

Two switching states (NPN/PNP) can be adjusted as switching points S1 and S2 (in %) for increase or degrease of process values (Smin/Smax adjustment). The value of each switching point and the hysteresis (in %) for each can be adjusted independently. Example: S1 max. adjustment fig. 7 Value S1max Hyst.1 Hyst.1 Alarm range * Time

With increasing flow rates the analogue output gives a rising output signal 4(0)...20 mA. The values 4(0) mA are programmable in the code mode. Further possible programming options in the code mode are: • the filter this means, the time of response (sensitivity against flow changes) is adjustable from 0,2 s up to 32 s (filter-off programming is possible) • the display range (start and end value) this means, the display value (0...100%) can be programmed for the optimal resolution of the flow range of the process (max. measuring range see technical data).
