(POS. 6.6-6.7) Function and the range of current output n.1-2
[OUT.mA1-2=X÷XX±]
Choice of the function and the range of current output N.1-2. The current output N.1 is optional and
it is mounted on the main board. There are three fields to modify for this function:
q Scale zero: 4 or 0 mA ; Full scale: 20 or 22 mA
q Field: + = positive, - = negative,
± = both, -0+ = central zero scale
The values corresponding to the scale points are shown in the following chart:
In hardware alarm conditions “HW ALARM” (interrupted coils, empty pipe, measure error) the current
value is programmed by the function “mA VALL. FAULT” (pos. 4.7) and it is expressed as percentage
of a fixed current range, where: 0% = 0 mA e 110% = 22 mA.
