Manual activation
•
On failure of the bus connection or a CPU stop the 3RW5 soft starter remains in
the "Automatic" mode or the 3RW5 soft starter switches to the "Automatic" mode.
Permanent activation
•
A switch to the "Automatic" mode and operating mode "manual - bus" is not
possible. If the 3RW5 soft starter is in the "Automatic" or "manual - bus" mode,
the 3RW5 soft starter switches to the "Manual operation local - input controlled"
mode. Control by means of a higher-level control (e.g. PLC) is not possible.

•
On failure of the bus connection or a CPU stop, the 3RW5 soft starter switches
from the "Automatic" mode to the "Manual operation local - input controlled" mode
or the 3RW5 soft starter remains in the operating mode "manual - local" mode.
No change on bus error
•
On failure of the bus connection or a CPU stop the master control function does
not switch, but the 3RW5 soft starter remains in the current mode.
