Minimum level monitoring with alarm, level control
Switching output (OU1): alarm
min. value reached again → alarm reset
below min. value → alarm
hysteresis function, normally open (Hno)
Analog output (OU2): level control
I (4 ... 20mA) or U (0 ... 10V)

10V / 20mA
OUT2
U / I
0V / 4mA
If the level is above SP1, output 1 switches. If the level falls below rP1
or if there is a wire break, output 1 switches back.
By the analog signal the maximum level can be controlled (start / stop
refilling).
