Function Description
The safety relay PNOZ X10.11P 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 X10.11P 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 X10.11P
– 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.
}Monitored start: Unit is active once
– the input circuit is closed and then the start circuit is closed and opened again.
– the start circuit is closed and then opened again once the input circuit is closed.
The LED "K3" lights when the start circuit is closed and goes out when the start circuit is
opened.
}Increase in the number of available contacts by connecting contact expandsion modules
or external contactors/relays.

}Use the notch on the rear of the unit to attach it to a DIN rail (35 mm).
}When installed vertically: Secure the unit by using a fixing element (e.g. retaining bracket
or end angle).

Wiring
Please note:
}Information given in the "Technical details [ 15]" must be followed.
}Outputs 13-14, 23-24, 33-34, 43-44, 53-54, 63-64 are safety contacts; outputs 71-72,
81-82, 91-92, 01-02 are auxiliary contacts (e.g. for display).
}Do not use auxiliary contacts 71-72, 81-82, 91-92, 01-02 for safety circuits!
}Do not connect undesignated terminals.
}To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details [ 15]).
}Calculation of the max. cable length lmax in the input circuit:
Rlmax
Rl / km
Imax =
Rlmax = max. overall cable resistance (see Technical details [ 15])
Rl/km = cable resistance/km
}Use copper wiring with a temperature stability of 60/75 °C.
}To prevent EMC interferences (particularly common-mode interferences) the measures
described in EN60204-1 must be executed. This includes the separate routing of cables
of the control circuits (input, start and feedback loop) from other cables for energy trans-
mission or the shielding of cables, for example.
}Do not switch low currents using contacts that have been used previously with high cur-
rents.
}Adequate protection must be provided on all output contacts with capacitive and inductive
loads.
}When connecting magnetically operated, reed proximity switches, ensure that the max.
peak inrush current (on the input circuit) does not overload the proximity switch.
}The power supply must comply with the regulations for extra low voltages with protective
electrical separation (SELV, PELV) in accordance with VDE 0100, Part 410.
Important for detection of shorts across contacts:
As this function for detecting shorts across contacts is not failsafe, it is tested by Pilz during
the final control check. If there is a danger of exceeding the cable runs, we recommend the
following test after the installation of the device:
1. Unit ready for operation (output contacts closed)
2. Short circuit the test terminals S12, S22 for detecting shorts across the inputs.
3. The unit's fuse must be triggered and the output contacts must open. Cable lengths in
the scale of the maximum length can delay the fuse triggering for up to 2 minutes.
4. Reset the fuse: remove the short circuit and switch off the supply voltage for approx. 1
minute.

Operation
When the relay outputs are switched on, the mechanical contact on the relay cannot be
tested automatically. Depending on the operational environment, measures to detect the
non-opening of switching elements may be required under some circumstances.
When the product is used in accordance with the European Machinery Directive, a check
must be carried out to ensure that the safety contacts on the relay outputs open correctly.
Open the safety contacts (switch off output) and start the device again, so that the internal
diagnostics can check that the safety contacts open correctly
}for SIL CL 3/PL e at least 1x per month
}for SIL CL 2/PL d at least 1x per year
NOTICE
The safety function should be checked after initial commissioning and each
time the plant/machine is changed. The safety functions may only be
checked by qualified personnel.
