Function Description
The safety relay PNOZ XV3P 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 reset circuit Y39-Y40 and the start circuit S13-S14 are closed.
}Input circuit is closed (e.g. E-STOP pushbutton not operated):
– The "START" LED is lit.
– The LEDs "CH.1", "CH.1 [t]", "CH.2" and "CH.2 [t]" are lit.
– Safety contacts 13-14, 23-24, 33-34, 47-48 and 57-58 are closed. The unit is active.
– The "START" LED goes out.
}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 and 33-34 are opened redundantly.
– Safety contacts 47-48 and 57-58 open after the delay time has elapsed.
– The LEDs "CH.1 [t]" and "CH.2 [t]" go out.
Before the unit can be restarted, the delay time must have elapsed and the unit must again
be ready for operation.
Set delay time:
On units with selectable delay time, the delay time of the safety contacts 47-48 and 57-58
can be set on the front of the unit using a screwdriver.
Reset function:
The delay time cycle can be ended prematurely by opening the reset circuit Y39-Y40. For
this purpose, one N/C contact is connected between Y39-Y40 instead of a link.

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 cir-
cuit, detects PNOZ XV3P
– 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
circuit, detects PNOZ XV3P
– 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.
}Monitored start: Unit is active once the input circuit is closed and once the start circuit is
closed after the waiting period has elapsed (see Technical details [ 17]).
}Increase in the number of available contacts by connecting contact expander modules
or external contactors/relays.

NOTICE
At the latest, the delay-on de-energisation safety contacts open after the set
delay time + 50 ms + 15% of the set value, even in the case of a component
failure.
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.
}Ensure the unit is mounted securely on a vertical DIN rail (35 mm) by using a fixing ele-
ment (e.g. retaining bracket or an end angle).

Wiring
Please note:
}Information given in the "Technical details [ 17]" must be followed.
}Delivery status of units with screw terminals: Link between S11-S12 (dual-channel input
circuit) and link between Y39-Y40 (reset circuit)
}Outputs 13-14, 23-24, 33-34 are instantaneous safety contacts, outputs 47-48, 57-58
are delay-on de-energisation safety contacts.
}Do not connect undesignated terminals.
}To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details [ 17]).
}Calculation of the max. cable runs lmax in the input circuit:
Rlmax
Rl / km
Imax =
Rlmax = max. overall cable resistance (see Technical details [ 17])
Rl/km = cable resistance/km
}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.
}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 protect-
ive electrical separation (SELV, PELV) in accordance with VDE 0100, Part 410.
}Ensure the wiring and EMC requirements of IEC 60204-1 are met.
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 length, we recommend
the following test once the unit is installed:
1. Unit ready for operation (output contacts closed)
2. Short circuit the test terminals S22, S32 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
NOTICE
Check each safety function
– after initial commissioning and after each change of the machine/
plant
– for SIL CL 3/PL e at least 1x per month, for SIL CL 2/PL d at least 1x
per year
Follow the instructions below:
– Activate the safety function and check whether all the used safety
contacts open.
– Prepare for operation again and start the unit. All the used safety
contacts must be closed again.
The safety functions may only be checked by qualified personnel.

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.
}In the case of an error, the delay-on de-energisation contacts may open before the
delay time has elapsed.
