Function Description
The two-hand control relay P2HZ X1is activated by simultaneously operating the two oper-
ator elements (simultaneity see Technical details [ 20]). 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. The "POWER" LED lights up.
} Both operator elements are operated within the simultaneity:
– Safety contacts 13-14, 23-24 and 33-34 close, auxiliary contact 41-42 is opened, the
device is active.
– LEDs "CH1" and "CH2" will light.
– A high signal is present at the semiconductor output switch state Y32.
} One operator element is released following simultaneous operation:
– Safety contacts 13-14, 23-24 and 33-34 are opened redundantly, auxiliary contact
41-42 is closed.
– The LED "CH1" or "CH2" goes out.
– A low signal is present at the semiconductor output switch state Y32.
} To activate the device again, both operator elements have to be released and then oper-
ated again within the simultaneity.
