MENU 6 - OUTPUTS
(POS. 6.1-4) Function corresponding to on/off output 1-2-3-4
[OUT1=XXXXXX]
Choice of the function corresponding to digital Output 1. The functions are listed in the table below:
(POS. 6.5) Function and the range of current output n.1
[OUT.mA1=X÷XX+]
Choice of function and range of current output N.1. There are three fields to modify:
Scale zero: 4 or 0 mA; Full scale: 20 or 22 mA
Field: + = positive, - = negative, blank = 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 v. fault” (pos. 4.6) and it is expressed as
percentage of a fixed current range, where: 0% = 0mA e 110% = 22mA.
