Adjustment and start-up
P
1
and P
2
are the values associated with a current of 4 mA or 20 mA respectively:
If P
1
is higher than P
2
, the signal is inverted and the range P
1
–P
2
corresponds to the range for the 20...4 mA
current.

Process value chosen
Fig. 32 : 4...20 mA current depending on the process value selected
4mA: choose the value of the process value (previously selected), associated with a current of 4 mA, for each
current output.
20mA: choose the value of the process value (previously selected), associated with a current of 20 mA, for each
current output.
FILTER: choose the level of damping for the fluctuations of the current value for each current output. Three
damping levels are proposed: slow, fast or none. The damping for the current outputs is similar to the damping of
the display (see Fig. 31).
MODE DIAG.: choose to emit a current of 22 mA on the current output selected when an “error” event related
to diagnostics (see chpt. 9.13.2, 9.13.3 and 9.13.4) is generated by the device or allow the current output to
operate normally (choose “none”).
An "error" event linked to a malfunction of the device is always indicated by the generation of a 22 mA
current, whatever the adjustment made in the function "MODE DIAG.".
