Setup-Global

Cascade Action

Select the control action between the inner and outer loop of a cas-
cade system.

• Direct action

[`dir] makes the percent output from the outer loop

directly proportional to the set point of the inner loop (input 2). A 100%
signal in the outer loop will set the inner loop to range high 2

[`rH2]

(Input Menu). A 0% signal in the outer loop will set the inner loop to
range low 2

[`rL2] (Input Menu).

• Reverse action

[`rEU] makes the percent output from the outer loop

inversely proportional to the set point of the inner loop (input 2). A 100%
signal in the outer loop will set the inner loop to range low 2

[`rL2]

(Input Menu). A 0% signal in the outer loop will set the inner loop to
range high 2

[`rH2] (Input Menu).
