[Out mA2=4_22+/-]
Current output
option and range
This function sets the current
output 2.
AL3 [OUT2F]
This function is optional and will not appear unless the option has been requested. There are three elds 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. 5.6) and it is expressed as percentage of a xed current range,
where: 0% = 0mA and 110% = 22mA.
