If the connection to the control source is aborted, the control priority automatically switches
back to the lowest priority of the current mode.
Depending on the 3RW5 soft starter and the parameter assignment, the lowest priority in
operating mode "Manual operation local" is "Input controlled" in the following cases:
● 3RW52 soft starter
● 3RW55 soft starter with one of the following parameter assignments:
– Input action "Manual operation local" is parameterized and switched on.
– A controlling input action (e.g. "Motor CW") is parameterized, but the input action
"Manual operation local" is not parameterized.
