KROHNE AF-E 400 - Device Functions with Factory Setting; Setting Options; 4 Functions and Features

4
3.1 Device functions with factory setting
Output OUT1:
• Switching signal for volumetric flow (hysteresis function normally open, PnP,
SP1 and rP1)
• Measured value damping 0.6 seconds, no start-up delay and minimal low flow
cut-off
• In case of a fault the output switches OFF
Output OUT2:
• Analogue signal for volumetric flow (measuring range unscaled)
• In case of a fault the analogue signal goes to 3.5 mA
Display:
• Text in English, colour of the characters black/white
• Simultaneous display of current process values for volumetric flow and
temperature and quantity meter
• Low refresh rate, 75 % display brightness
3.2 Setting options
• Output functions of OUT1 and OUT2 (temperature or volumetric flow;
switching, pulse, frequency, analogue signal, totaliser function)
• Reversal of the volumetric flow direction, monitoring of the volumetric flow
• Response times for volumetric flow measurement (measured value damping,
start-up delay, low flow cut-off)
• Error behaviour of the outputs
• Standard views of the display (unit of measurement, process values, quantity
meter, refresh rate, rotation, brightness, process value-dependent change of
the colour of the characters)
4 Functions and features
The unit monitors liquid media. It detects flow velocity, volume flow (volumetric
flow quantity/time), consumed quantity and medium temperature.
