Function Description
The safety relay PNOZ X7P provides a safety-oriented interruption of a safety circuit. When
the supply voltage is applied via the E-STOP pushbutton, the “POWER” LED is lit. The unit
is ready for operation when the start circuit and feedback loop Y1-Y2 is closed.
} Input circuit is closed (e.g. E-STOP pushbutton not operated):
– The LED "CH. 1/2" lights.
– Safety contacts 13-14 and 23-24 are closed. The unit is active.
} Input circuit is opened (e.g. E-STOP pushbutton operated):
– The LED "CH. 1/2" goes out.
– Safety contacts 13-14 and 23-24 are redundantly opened.
Operating modes
} Single-channel operation: No redundancy in the input circuit, earth faults in the start
and input circuit are detected.
} Automatic start: Unit is active once the input circuit has been closed.
} Manual start: Unit is active once the input circuit and the start circuit are closed.
} Increase in the number of available contacts by connecting contact expander modules
or external contactors/relays.
