Page 6: Use Of Qualified Personnel
PZE X4 Use of qualified personnel The products may only be assembled, installed, programmed, commissioned, operated, maintained and decommissioned by competent persons. A competent person is a qualified and knowledgeable person who, because of their train- ing, experience and current professional activity, has the specialist knowledge required. To be able to inspect, assess and operate devices, systems and machines, the person has to be informed of the state of the art and the applicable national, European and international laws, directives and standards. -
Page 7: Unit Features
PZE X4 Unit features Positive-guided relay outputs: – 4 safety contacts (N/O), instantaneous LED display for: – Switch status of the safety contacts Connection for feedback loop Operation: single-channel Safety features The unit meets the following safety requirements: The contact expander module expands an existing circuit. As the output relays are monitored via the base unit's feedback loop, the safety functions on the existing circuit are transferred to the contact expander module. -
Page 8: Function Description
PZE X4 Function description The contact expansion module PZE X4 is an add-on device without delay-on de-energisa- tion, and it is used to expand a safety circuit. The contact expansion module is driven by a base unit (e. g. emergency stop relay). Functional procedure once the input circuit is closed (e.g. -

Preparing for operation Supply voltage 24 V DC Input circuit Single-channel Dual-channel Base unit: 24 V DC PNOZ X Driven via safety contacts Base unit: PNOZmulti or PNOZelog Driven via semiconductor outputs (24 V DC) Base unit: PNOZmulti or... -
Page 10: Operation
PZE X4 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. -
