* For a pressure probe with a
range of 0-30 bar, set Min=0 and
max=30.0. Pay attention to the
decimal point.

Aunction performed by the input/output. The function is selected from
among those listed in the “Application Function” column.
Analog input eective range of working (“Range Min%” and “Range Max%” columns).
Only for active probes. It is the percentage dening the real working range of the probe.
Analog input over range admission. States if an error is generated when the input signal
is outside its eective working range. If “Overrange=NO” an alarm is generated.

* means that the Analog Input
1 is of 0/5V type and it is used
for measuring pressure. As 10%
(“Range Min%” value) of (5 - 0)V
is 0.5V, and 90% is 4.5V then AI1
eective range is 0.5V – 4.5V and
it measures 0 bar at 0.5V and
30bar at 4.5V. Outside this range
an alarm is generated.
» analog input lter. If “Filter=1” the analog input measure is not ltered. The measure is faster but less stable. If
“Filter=128” lter is at its maximum. Suggested values goes from 1 to 16..
