8.4 Level measurement with limitated
display range
A third example is level measurement with
limited display range, that means a tank
with 10 m3 have to be filled up at best to 8
m3 and its the level should not decrease
below 1 m3. At values > 8 m3 the display
shows „hi“ and at values < 1 m3 the dis-
play shows „lo“.
4..20 mA is chosen as input range.
Assign 0 as „displayed value at min. input
signal“ to the lowest input level and 10 as
„displayed value at max. input signal“to the
highest input level.
Additionally at menu title „min. input sig-
nal“ the value which corresponds to the 1
m3 level, e.g. 5.6 mA is programmed. Do
the same with the value which corre-
sponds to the 8 m3 level, e.g. 16.8 mA.
At input levels > 16.8 mA „hi“ will be dis-
played and at input levels < 5.6 mA „lo“.
