4.4.4 3-point stepping controller (relay & relay)
ConF/Cntr: SP.Fn = 0 set-point / cascade controller
C.Fnc = 4 3-point stepping controller inverse action (e.g.
heating applications)
C.Act = 0 action Out.1 direct
ConF/Out.1: O.Act = 0 control output Y1 active
Y.1 = 1 control output Y2 not active
Y.2 = 0 action Out.2 direct
ConF/Out.2: O.Act = 0 control output Y1 not active
Y.1 = 0 control output Y2 active
Y.2 = 1 proportional band 1 (heating) in units of phys.
quantity (e.g. °C)
PArA/Cntr: Pb1 = 1...9999 integral time 1 (heating) in sec.
ti1 = 0,1...9999 derivative time 1 (heating) in sec.
td1 = 0,1...9999 min. cycle time 1 (heating)
t1 = 0,4...9999 neutral zone in units of phy. quantity
SH = 0...9999 min. pulse length in sec.
tP = 0,1...9999 actuator travel time in sec.
tt = 3...9999 set-point limit low for Weff
PArA/SEtP: SP.LO = -1999...9999 set-point limit high for Weff
SP.Hi = -1999...9999 set-point / cascade controller

For direct action of the 3-point stepping controller, the controller output action
must be changed (
ConF / Cntr / C.Act = 1 )
