Function Description
The safety relay PNOZ XV2P 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 XV2P
  – 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 [ 16]).

• Increase in the number of available contacts by connecting contact expansion modules or external contactors/relays.

NOTICE
At the latest, the delay-on de-energization 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 (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 [ 16]” 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-energization safety contacts.

•  Do not connect undesignated terminals.

• To prevent contact welding, a fuse should be connected before the output contacts (see Technical details [ 16]).

• Calculation of the max. cable length lmax in the input circuit:
  Rlmax = max. overall cable resistance (see Technical details [ 16])
  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 transmission 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 currents.

• 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 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 3/PL e at least 1x per month
• for SIL 3/PL d at least 1x per year

NOTICE
The safety functions should be checked after initial commissioning and each time the plant/machine is changed. The safety functions may only be checked by qualified personnel.
Status indicators
LEDs indicate the status and errors during operation:

• LED on

• POWER
  Supply voltage is present.

• START
  Start circuit is closed.

• CH.1
  Safety contacts of channel 1 are closed.

• CH.2
  Safety contacts of channel 2 are closed.

• CH.1 [t] Channel 3 safety contacts are closed.

• CH.2 [t] Channel 4 safety contacts 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.

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

Explanatory notes for the safety-related characteristic data:

• Safety characteristic data in accordance with EN IEC 62061 and EN/IEC 61511 was calculated based on EN/IEC 61508.

• TM is the maximum mission time in accordance with EN ISO 13849-1. The value also applies as the retest interval in accordance with EN/IEC 61508-6 and EN/IEC 61511 and
  as the proof test interval and mission time in accordance with EN IEC 62061.

• All the units used within a safety function must be considered when calculating the safety characteristic data.

INFORMATION
A safety function’s SIL/PL values are not identical to the SIL/PL values of the units that are used and may be different. We recommend that you use the Pascal software tool to calculate the safety function’s SIL/PL  values.
Supplementary data
**CAUTION!
It is essential to consider the relay’s service life graphs. The relay outputs’ safety-related characteristic data is only valid if the values in the service life graphs are met.
The PFH value depends on the switch frequency and the load of the relay output.
If the service life graphs are not accessible, the stated PFH value can be used irrespective of the switch frequency and the load, as the PFH value already considers the relay’s B10d value as well as the failure rates of  the other components.
Service life graph**
The service life graphs indicate the number of cycles from which failures due to wear must be expected. The wear is mainly caused by the electrical load; the mechanical load is negligible.

Example

• Inductive load: 0.2 A
• Utilisation category: AC15
• Contact service life: 4 000 000 cycles

Provided the application to be implemented requires fewer than 4 000 000 cycles, the PFH value (see Technical details) can be used in the calculation.
To increase the service life, sufficient spark suppression must be provided on all output contacts. With capacitive loads, any power surges that occur must be noted. With DC contactors, use flywheel diodes for spark
suppression.
Remove plug-in terminals
Procedure

• Insert a suitable screwdriver into the housing recess behind the terminal. Do not remove the terminals by pulling the cables!
• Lever the terminal out.
