  • Page 10: Function Description

    P2HZ X1P Function Description The two-hand control relay P2HZ X1P is activated by simultaneously operating the two op- erator 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.

    Use the notch on the rear of the unit to attach it to a DIN rail (35 mm). When installed vertically: Secure the unit by using a fixing element (e.g. retaining bracket or end angle). Operating Manual P2HZ X1P 19799-EN-08...

  • Page 12: Wiring

    Use copper wire that can withstand 60/75 °C. The supply voltage must be switched off with the operating energy of the machine. The connection cables between the P2HZ X1P and the pushbuttons should not be laid directly next to power cables, otherwise inductive and capacitive interference coupling can result.

  • Page 13: Preparing For Operation

    Open the safety contacts (switch off output) and start the device again, so that the internal diagnostics can check that the safety contacts open correctly for SIL CL 3/PL e at least 1x per month for SIL CL 2/PL d at least 1x per year Operating Manual P2HZ X1P 19799-EN-08...
