On machines which have a high potential for injury, e.g. presses, shearing and punching machines with two hand controls, both of the operator's hands must be located outside the hazardous area before the hazardous machine movement can be initiated.
In order to protect the operating personnel, it is necessary that the two hand control is operated with both hands simultaneously within a time window of 500 ms, in order to operate the machine or to keep the machine in an operational state.
