Remote RESET (RESET MODE LED = green)
You can reset a fault signal by disconnecting the control supply voltage for >1.5 s.

AUTO RESET (RESET MODE LED = yellow)
If you set the RESET mode to AUTO, a fault is automatically reset.
Note
For information about whether or not faults can be acknowledged, as well as the recovery
time and the corresponding LED and output contact states, refer to chapter Diagnostics and
fault signals [Page 44].
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 on the 3RW40 (terminals 95 and 96), or the signaling contact
of the motor or miniature circuit breaker on all devices, in the controller.
