Reverse PID (fb41) action

Hi everyone

currently am working on (PID level control) on factory I/O

am using 2* PIDs for filling and discharging. in the filling process, everything works great even when activating MAN (manual mode)

with the discharge process, i have set the following parameters as follows (picture) , this allows to invert the PID action

but when I set the MAN value to 90% the LMN=10 if MAN=80% the=20 it’s like he is Completing to 100% (in manual mode)
how to solve it

kind regards
