Explanation for the lowest priority in the operating mode "Manual operation local" in the following text.
If the connection to the control source is aborted, the control priority automatically switches
back to the lowest priority of the current mode.
Example: Control priority is with the 3RW5 HMI. If the connection to the 3RW5 HMI is
aborted, the control priority automatically switches back to "Manual operation local - Input
controlled" or "Manual operation local - Connection abort" (depending on the
3RW5 soft starter and the parameter assignment).
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.
Note
Response of 3RW52 soft starter in the event of bus connection failure
To enable you to continue control
ling the 3RW52 soft starter in "Automatic" mode after
failure of the bus connection, you require a 3RW5
HMI (accessory) which enables you to
switch to "Manual operation local" mode.
Without 3RW5
HMI, you cannot control the 3RW52 soft starter until the bus connection has
been restored.
Alternatively, you can remove the
3RW5 communication module (Page 33
). Then restore the
3RW52
soft starter on the device to the factory setting, in order to switch to the
"Manual operation local
- Input controlled" mode. You will find more information on restoring
the factory setting on the device in the Equipment Manual of the 3RW52
soft starter.
