Automated machinery provided with automatic or remote control system, as well as, to the necessary extent, with monitoring systems, is in addition to be provided with means of local control.
In each case of failure in automatic or remote control systems, the possibility of local control is to be maintained.
Where machinery or installation is remotely controlled, it should be possible for the operator to check, with sufficient reliance, from his control station whether his command has been carried out by remote control system.
