In case the tool is locked while a user attempts to start a service (normally tightening or loosening), the Power Focus will show an event code to explain why or by which functionality the tool is locked. In case the tool becomes locked while a service is performed, the service will be aborted and an event code explaining why or by which functionality the tool was locked will be displayed.
The event codes messages generated because the tool is locked do contain two integer parameters that can be viewed from the event log.
