Function Description
The safety relay PNOZ X11P provides a safety-oriented interruption of a safety circuit.
When supply voltage is supplied the "POWER" LED is lit. The unit is ready for operation
when the feedback loop Y1-Y2 and the start circuit S33-S34 are closed. The "START" LED
is lit.
} Input circuit is closed (e.g. E-STOP pushbutton not operated):
– The LEDs "CH.1IN" and "CH.2 IN" are lit.
– The "START" LED goes out.
– Safety contacts 13-14, 23-24, 33-34, 43-44, 53-54, 63-64 and 73-74 are closed,
auxiliary contact 81-82 is opened. The unit is active.
– The LEDs "CH.1" and "CH.2" are lit.
– A high signal is present at the semiconductor output switch state Y32.
} Input circuit is opened (e.g. E-STOP pushbutton operated):
– The LEDs "CH.1IN" and "CH.2 IN" go out.
– Safety contacts 13-14, 23-24, 33-34, 43-44, 53-54, 63-64 and 73-74 are opened re-
dundantly, auxiliary contact 81-82 is closed.
– The LEDs "CH.1" and "CH.2" go out.
– A low signal is present at the semiconductor output switch state Y32.
Semiconductor output supply voltage Y35
} A high signal is present at semi-conductor output Y35 if the supply voltage is present
and the internal fuse has not blown.
