Function Description
The safety relay PNOZ X10.1 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 not operated):
– LEDs "CH.1 IN", "CH.2 IN" and "K3" go out.
– LEDs "K1" and "K2" light as soon as relays K1 and K2 are in operating position
– LED "K3" goes out as soon as relay K3 is in rest position.
– 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 IN" and "CH.2 IN" go out.
– LEDs "K1" and "K2" go out as soon as relays K1 and K2 are in rest position.
– 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 X10.1 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 X10.1
– earth faults in the start and input circuit,
