MENU 6 - OUTPUTS
(POS. 6.1) Function choice corresponding to on/off output 1 [Out
1=XXXXXX]
Function choice corresponding to digital Output 1. The functions are listed in the table below.
(POS. 6.2) Function choice corresponding to on/off output 2 [Out
2=XXXXXX]
Function choice corresponding to digital Output 2. The functions are listed in the table below.
(POS. 6.3) Current output option and range [Out mA=X_XX XXX]
This function sets the current output N.1. This function is optional and will not appear unless the
option has been requested. There are three fields to modify for this function:
 Scale zero: 4 or 0mA
 Full scale: 20 or 22mA
 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 “HARDW AL.” (interrupted coils, empty pipe, measure error) the
current value is programmed by the function “mA v.fault” (pos. 4.4) and it is expressed as
percentage of a fixed current range, where: 0% = 0mA and 110% = 22mA.
