NIO Acknowledgement
When the bolting process (bolting and unbolting) is false, all following power tool starts are ignored and
an error message is output. Further bolting processes are possible only after an NIO acknowledgement.
The acknowledgement of a false bolting process is possible via the “NIO-Quit” key switch or via the pushbutton
of the connected power tool. The NIO acknowledgement of the BMS interface is blocked for manual power tool
operation.
Key switch in center position:
– NIO acknowledgement active on power unit
– NIO acknowledgement by turning key switch to the right
Key switch in left position:
– NIO acknowledgement active on power tool
– NIO acknowledgement by actuating NIO reset button on power tool
NOTE:
A NIO acknowledgement is not possible by a reset or by switching the power unit on/off.
