Function Description
The safety relay PNOZ X10 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 S12-S34 are closed.
} Input circuit is closed (e.g. E-STOP pushbutton is not operated):
– The LEDs "CH.1" and "CH.2" are lit.
– Safety contacts 13-14, 23-24, 33-34, 43-44, 53-54 and 63-64 are closed, auxiliary
contacts 71-72, 81-82, 91-92 and 01-02 are opened. The unit is active.
} Input circuit is opened (e.g. E-STOP pushbutton operated):
– The LEDs "CH.1" and "CH.2" go out.
– Safety contacts 13-14, 23-24, 33-34, 43-44, 53-54 and 63-64 are opened redund-
antly, auxiliary contacts 71-72, 81-82, 91-92 and 01-02 are closed.
Operating modes
} Single-channel operation: No redundancy in the input circuit, earth faults in the start and
input circuit are detected.
} Dual-channel operation with detection of shorts across contacts: Redundant input circuit,
PNOZ X10 detects
– earth faults in the start and input circuit,
– short circuits in the input circuit,
– shorts across contacts in the input circuit.
} Dual-channel operation without detection of shorts across contacts: Redundant input cir-
cuit, detects PNOZ X10
– earth faults in the start and input circuit,
– short circuits in the input circuit.
} 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.
