Withdrawal of control by other control sources
Master control is withdrawn from the input IN or digital inputs as follows:
• Command in SIRIUS Soft Starter ES (TIA Portal) Premium / Professional (fieldbus)
Brief overview: Window "Task Card" > Tab "Online Tools" > "SIRIUS Control Panel > Master
Control > Get Control"
Note
Fetching control from "Automatic operation - input controlled" mode
The "Automatic operation - input controlled" mode is possible for the following 3RW5 soft
starters:
• 3RW55 soft starter from firmware version V2.1
• Soft starter 3RW55 Failsafe with firmware version V1.1.0 or higher
• Command in the web server
Web page "Control Panel" > "Master Control > Get Control"
Note
Fetching control from "Automatic operation - input controlled" mode
The "Automatic operation - input controlled" mode is possible for the following 3RW5 soft
starters:
• 3RW55 soft starter from firmware version V2.1
• Soft starter 3RW55 Failsafe with firmware version V1.1.0 or higher
• "LOCAL / REMOTE" action on the 3RW5 HMI
• Command in SIRIUS Soft Starter ES (TIA Portal) (local interface on the 3RW5 HMI High
Feature)
Brief overview: Window "Task Card" > Tab "Online Tools" > "SIRIUS Control Panel > Master
Control > Get Control"
Operating mode "Manual operation local - HMI controlled"
Fetching control
The 3RW5 HMI actively fetches master control via the action "LOCAL / REMOTE" from the lower
priority control source.
If master control at the local interface on the 3RW5 HMI High Feature (higher priority), you must
first actively give up master control in SIRIUS Soft Starter ES (TIA Portal). You can then get master
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 33) is set
to "Permanent activation".
