This controller type can be used as a fixed setpoint controller with 2 independent setpoints (two
batch mode) or as a fixed setpoint controller with 1 setpoint, by blocking the Internal/External
switching (factory setting). By linking the inputs x1, x2, x3 with the constants c1, c2, c3, it can
be used as a three-component controller.
Switching between the two internal setpoints which are adjustable on the front separately as
one, two or three component takes place depending on the control signals Int and CB according
to table 1-5. Signaling of the active setpoint takes place on the LEDs Internal and C. As soon as
a LED lights, wi2 is active.
1)
follow up takes place at S52 = 0 and S50 = 1 to the controlled variable x, follow--up does not apply for the switching
wi1/wi2
at S52 = 1 automatic mode starts with wi=x (xd=0), the active setpoint runs to the old set value via the possibly set setpoint
ramp tS
2)
factory setting, fixed setpoint controller with 1 setpoint (S49 = 0: only Internal, Int = 1, S24 = -1: CB = 1) RB = Int
