DANGER
The Limit switch override is used to disconnect safety limitations. Make sure the
Limit switch override function is not active longer than absolutely necessary.
If the option SafeMove is implemented, Limit switch override must never be used
at all. The SafeMove safety controller has its own override function.
Note
The parts needs to be ordered separately from ABB and are not part of an option
package.
