4.4.2 2-point controller (inverse)

ConF / Cntr: SP.Fn = 0 set-point controller

C.Fnc = 1 2-point controller (PID)

C.Act = 0 inverse action

(e.g. heating applications)

ConF / Out.1: O.Act = 0 action Out.1 direct

Y.1 = 1 control output Y1 active

PArA / Cntr: Pb1 = 1...9999 proportional band 1 (heating)

in units of phys. quantity (e.g. °C)

ti1 = 0,1...9999 integral time 1 (heating) in sec.

td1 = 0,1...9999 derivative time 1 (heating) in sec.

t1 = 0,4...9999 min. cycle time 1 (heating)

PArA / SEtP: SP.LO = -1999...9999 set-point limit low for Weff

SP.Hi = -1999...9999 set-point limit high for Weff

For direct action, the controller action must be changed

(ConF / Cntr / C.Act = 1 ).
