output. The primary process variable is AI1 and the secondary pro-
cess variable is AI2. The output of the primary PID controller
becomes the set point for the secondary PID controller. The output of
the secondary control loop is AO2.
When two temperature inputs are required, the option card must be
installed and the temperature input type selected from the
SETUP-OPTIONS-OPTION BOARD
menu. The primary temperature
input becomes AI3 and AI4 is the secondary temperature input. This
configuration is shown in Figure
