Description
3.7 Operating modes and master control function
"Manual operation local - input controlled" and "Automatic - input controlled" mode
Fetching control
The input IN or the digital inputs fetch control from the "Automatic" mode as follows:
● 3RW50, 3RW52 soft starters and for 3RW55 and 3RW55 Failsafe soft starters if the input
action "Operating mode manual - local" is not parameterized: by enabling the
"Manual operation local - input controlled" bit in the data table
"Process image outputs (PIQ)" (Page 150).
● For 3RW55 and 3RW55 Failsafe soft starters if the input action
"Operating mode manual - local" is parameterized: by enabling the input action
"Operating mode manual - local".
If the master control function is on the 3RW5 HMI or, in the case of the local interface, on the
3RW5 HMI High Feature (higher priority), you must actively give up the master control
function beforehand. The input IN or the digital inputs can then fetch control.
Giving back control
"Automatic" mode fetches control as follows:
● 3RW50, 3RW52 soft starters and for 3RW55 and 3RW55 Failsafe soft starters if the input
action "Operating mode manual - local" is not parameterized: by disabling the
"Manual operation local - input controlled" bit in the data table
"Process image outputs (PIQ)" (Page 150).
● For 3RW55 and 3RW55 Failsafe soft starters if the input action
"Operating mode manual - local" is parameterized: By deactivating the input action
"Operating mode manual - local".
Withdrawal of master control by other control sources
Control is withdrawn from the input IN or digital inputs as follows:
● "LOCAL / REMOTE" action on the 3RW5 HMI
● Command in SIRIUS Soft Starter ES (TIA Portal)
(local interface on the 3RW5 HMI High Feature)
