a) SCALE Function
33 Establish a linear relation between input signal on PCA-570 and what is shown in to display, according to the
graphic below.
The indication in to display staggered (#) can be changed to represent any unit, such as: m/s, m3/s, %, etc.
The number of decimal digits shown in to display is configurable it 0 to 4.
The upper input value must necessarily be higher that the lower input value. Conversely, the scale values
upper and lower can be having any relationship with each other: biggest, smaller or equal and including being
signaled. Therefore, can be establishing relations direct or reverse.
The contact input can't be staggered.
