Function Description
The safety relay PNOZ X7 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/CH.2" will light.
– Safety contacts 13-14 and 23-24 are closed. The unit is active.
}Input circuit is opened (e.g. E-STOP pushbutton operated):
– The LEDs "CH.1" and "CH.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.

Installation
}The unit should be installed in a control cabinet with a protection type of at least IP54.
}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 [ 14]" must be followed.
}Calculating the max. cable length Imax in the input circuit on PNOZ X7 24 VAC/DC:
Rlmax
Rl / km
Imax =
Rlmax = max. overall cable resistance (see Technical details [ 14])
Rl/km = cable resistance/km
}Calculating the max. cable length Imax in the input circuit on PNOZ X7 AC units:
C
C
Clmax = max. overall line capacitance (see Technical details [ 14])
Cl/km = line capacitance/km
Stub circuit: The max. permitted cable length Imax depends on the max. overall line ca-
pacitance Clmax (see Technical details [ 14]).
Alternative: Loop circuit: Capacitance is negligible; 1 phase: Max. cable length Imax: 1

WARNING!
If the max. overall line capacitance is exceeded, the unit will no longer
switch off safely and serious injuries and death may result.
Always comply with the max. overall line capacitance.

}The outputs 13-14, 23-24 are safety contacts.
}Do not connect undesignated terminals.
}To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details [ 14]).
}Use copper wire that can withstand 60/75°C.
}Sufficient fuse protection must be provided on all output contacts with capacitive and in-
ductive loads.
}Do not switch low currents using contacts that have been used previously with high cur-
rents.
}On AC units: Connect operational earth terminal to functional earth.
}On 24 VAC/DC units:
The power supply must comply with the regulations for extra low voltages with safe
electrical separation (SELV, PELV) in accordance with VDE 0100, Part 410.
}Ensure the wiring and EMC requirements of EN 60204-1 are met.

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.

Supply voltage is present.
CH.1/CH.2
Safety contacts of channel 1 and 2 are closed.
Faults – Interference
}Earth fault: The supply voltage fails and the safety contacts open. Once the cause of
the respective fault has been rectified and the supply voltage is switched off for approx.
1minute, the unit is ready for operation again.
}Contact malfunctions: If the contacts have welded, reactivation will not be possible after
the input circuit has opened.
}LED "POWER" does not light: Short circuit or no supply voltage.
