  • Page 8: Function Description

    P2HZ X3 Function Description The two-hand control relay P2HZ X3 is activated by simultaneously operating the two oper- ator elements (simultaneity see Technical details [ 15]). If one or both of the operator elements are released, it interrupts the control command to close the press. The device is ready for operation when the supply voltage is applied and the feedback loop Y1-Y2 is closed.
