Function Description
The safety relay PNOZ X6 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 start circuit and feedback loop Y1-Y2 is closed.

  • Input circuit is closed (e.g. safety gate closed):
    – The LEDs “CH.1” and “CH.2” are lit.
    – The safety contacts 13-14, 23-24 and 33-34 are closed. The unit is active.

  • Input circuit is opened (e.g. safety gate opened):
    – The LEDs “CH.1” and “CH.2” go out.
    – Safety contacts 13-14, 23-24 and 33-34 are opened redundantly.

Operating modes

  • Single-channel operation: No redundancy in the input circuit, earth faults in the start and input circuit are detected.

  • Dual-channel operation without detection of shorts across contacts: Redundant input circuit, detects PNOZ X6
    – 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.

  • Increase in the number of available contacts by connecting contact expandsion 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 [ 17]” must be followed.
  • The output contacts 13-14, 23-24, 33-34 are 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 length lmax in the input circuit:

Rlmax = max. overall cable resistance (see Technical details [ 17])
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.
  • With 24 V AC/DC units: The power supply must meet the regulations for extra low voltages with protective electrical separation (SELV, PELV).

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

PILZ PNOZ X6 Safety Relays - icon 3NOTICE
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.
| CH.1
Safety contacts of channel 1 are closed.
| CH.2
Safety contacts of channel 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.

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.

PILZ PNOZ X6 Safety Relays - Supplementary data 1

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.
