Operating mode "Manual operation local - HMI controlled"
Fetching control
The 3RW5 HMI actively assumes the master control function via the action
"LOCAL / REMOTE" from the lower priority control source.
If the master control function at the local interface on the 3RW5 HMI High Feature
(higher priority), you must actively give up the master control function beforehand in
SIRIUS Soft Starter ES (TIA Portal). You can then get control with the action
"LOCAL / REMOTE".
Giving back control
The 3RW5 HMI actively gives up the master control function via the action
"LOCAL / REMOTE" to the "Automatic" mode or alternatively to the input IN or the digital
inputs. In the following cases, the master control function is given back to input IN or the
digital inputs:
● No 3RW5 communication module installed in the 3RW5 soft starter or connected to
the 3RW50 soft starter.
● 3RW50 and 3RW52 soft starters: The parameter "Control via digital input" (Page 39) is
set to "Permanent activation".
Withdrawal of master control by other control sources
In the event of a corresponding command in SIRIUS Soft Starter ES (TIA Portal) at the local
interface on the 3RW5 HMI High Feature, the master control function is taken from
the 3RW5 HMI.
