The function is applied if there is a requirement for the DOL 31 output to be cut off completely at a certain volt-
age on the analog control signal (turn off limit).

If the turn off limit is set to 0 V, the function is inactive and the DOL 31 output will remain at minimum (not in-
verted) or maximum (inverted).
