Positioning Signal Limitation
Purpose Limit the range of the output value sent to a positioning signal. For example, limit the
range of values sent to a damper to from 0 to 100 percent.
As shown in the following diagram, a function output can vary across all real
numbers. However, the device being controlled may have a set range between a
minimum and a maximum value.
Control Icons Use the MIN and MAX control icons.
Example If the linear function Y = 2X-20 (where -50 < X < 150) defines the output signal for a
mixing valve with a three-position output (0 through 100 percent range), you need to
limit the output to range between 0 and 100.
