Function Description
The safety relay PNOZ XV2.1P 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]" and "CH.2", "CH.2 [t]" are lit.
– The safety contacts 13-14, 23-24, 37-38 and 47-48 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 and 23-24 are redundantly opened.
– Safety contacts 37-38 and 47-48 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 37-38 and 47-48
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 circuit,
detects PNOZ XV2.1P
– earth faults in the start and input circuit,
– short circuits in the input circuit,
– Shorts across contacts 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 [ 15]).
}Increase in the number of available contacts by connecting contact expandsion modules
or external contactors/relays.

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 (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.
}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 are instantaneous safety contacts, outputs 37-38, 47-48 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 [ 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.
}Adequate protection must be provided on all output contacts with capacitive and inductive
loads.
}Do not switch low currents using contacts that have been used previously with high cur-
rents.
}Connect operational earth terminal to functional earth.
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.

INFORMATION
With automatic start, S33 and S34 must not be linked; with monitored
start, S13 and S14 must not be linked.
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 3/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.

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.
