3.4.11 Software-ST and locking of the control release
di.36 software ST input sel., di.37 ST lock input sel., di.38 turn off ST delay time
The function is switched off, if no input is selected in di.36. ST can be selected neither as software ST nor as
input for locking.
At voltage failure the control release can remain controlled with the locking function (although if the controlled
SPS fails).
A condition is that the terminal ST is bridged!
The switching off of an input (selection in di.36) is delayed by the time adjusted in di.38. Within this time the
locking input must become active (selection in di.37) in order to ensure the function.
