Other Functions Of The Reset Button - Siemens SIRIUS 3RW30 Manual

5.4.2.4 AUTO RESET
AUTO RESET (AUTO LED = yellow)
If you set the RESET mode to AUTO, a fault is automatically reset as follows:
• If the motor overload protection function trips: after 60 s
• If the intrinsic device protection function trips: after 30 s
Automatic restart
Can result in death, serious injury, or property damage.
The automatic RESET mode (AUTO RESET) must not be used in applications where
there is a risk of serious injury to persons or substantial damage to property if the motor
starts up again unexpectedly. The start command (e.g. issued by a contact or the PLC)
must be reset prior to issuing a RESET command because the motor attempts to restart
again automatically following this RESET command if a start command is still present.
This particularly applies if the motor protection has tripped. For safety reasons, you are
advised to integrate the group fault output (terminals 95 and 96) in the controller.
5.4.2.5 Acknowledging faults
For information about whether or not faults can be acknowledged as well as the
corresponding LED and output contact states, refer to chapter Diagnostics and fault signals
[Page 44].
