(POS. 42) Choice of the function and the range of current output n.1[OUT.mA1=X÷XX ±]

Choice of the function and the range of current output N.1. The current output N.1 is optional and it is mounted on the

main board. There are three field to modify for this function:

?? Scale zero: 4 or 0 mA

?? Full scale: 20 or 22 mA

?? Field: + = positive, - = negative, ? = both, -0+ = central zero scale

The values corresponding to the scale points are shown in the follwing chart:

In hardware alarm conditions (interrupt coils, empty pipe, measure error) the current value is programmed by

the function “mA VALL. FAULT” (page 49 pos. 28) and it is expressed as percentage of a fixed current range,

where: 0% = 0 mA e 110% = 22 mA.
