Function Description
The safety relay PNOZ X8P 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):
– LEDs "CH1 IN" and "CH2 IN" will light.
– The "START" LED goes out.
– Safety contacts 13-14, 23-24 and 33-34 are closed, auxiliary contacts 41-42 and
51-52 are opened. The unit is active.
– LEDs "CH1" and "CH2" will light.
– A high signal is present at the semiconductor output switch state Y32.
} Input circuit is opened (e.g. E-STOP pushbutton operated):
– LEDs "CH1 IN" and "CH2 IN" go out.
– Safety contacts 13-14, 23-24 and 33-34 are opened redundantly, auxiliary contacts
41-42 and 51-52 are closed.
– The LEDs "CH1" and "CH2" go out.
– A low signal is present at the semiconductor output switch state Y32.
