Page 10: Function Description
P2HZ X4P Function Description The two-hand control relay P2HZ X4P is activated by simultaneously pressing the two oper- ator elements (simultaneity see Technical details [ 19]). 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. -
