Control Loop
Control Loop
In this configuration the value read by one of the two inputs becomes the main
control setpoint:
• If par. 15
c.Pro.
is set as
Pro.1
, AI1 becomes the main process (command) and AI2
becomes the setpoint value;
• If par. 15
c.Pro.
is set as
Pro.1
, AI2 becomes the main process (command) and AI1
becomes the setpoint value.
Remote setpoint function works only with one of these two settings of par. 15
c.Pro.
