Automatic restart following Reset.
Can cause death or serious injury.
If the DEVICE LED shows a yellow light and the FAILURE LED a red light, and a manual
RESET or auto RESET takes place following an overload trip, the machine starts up
immediately if there is a control command at IN1/IN2. Personnel in the danger area can be
injured.
Make sure that the danger area of the machine is kept clear of people.
Reset in manual operation
If the RESET method is set to manual RESET, acknowledge an overload trip as follows:
1. Wait for the cooling time to elapse.
2. Press the "TEST/RESET/RESET MODE" button to acknowledge.
As an alternative, in the case of the 3RM10/3RM12 Standard motor starters, you can use
the RESET control input IN3 for acknowledgment.
Note
If you briefly switch the control supply voltage off and on again, there is no automatic
acknowledgment.
