PZE X4V Use of qualified personnel The products may only be assembled, installed, programmed, commissioned, operated, maintained and decommissioned by competent persons. A competent person is someone who, because of their training, experience and current professional activity, has the specialist knowledge required to test, assess and operate the work equipment, devices, systems, plant and machinery in accordance with the general standards and guidelines for safety technology.
PZE X4V } See order reference for unit types 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. } The safety function remains effective in the case of a component failure. } Earth fault in the feedback loop: Detected, depending on the base unit that is used.
PZE X4V } Functional procedure once the input circuit is opened (e.g. safety contacts on the base unit are opened): – The supply voltage is not present at input (A1) of the contact expansion module. – The LEDs "CH.1" and "CH.2" go out. – Safety contacts 17-18, 27-28, 37-38 and 47-48 are opened redundantly once the delay time has elapsed. NOTICE At the latest the safety contacts open after the delay time tv + 50% of the value, even in the case of a component failure.

PZE X4V Faults – Interference By closing or interrupting the input circuit you can check whether the unit switches on or off correctly. For safety reasons, the unit cannot be started if the following faults are present: } Contact malfunction: As the contact block is connected to a base unit, reactivation will not be possible if the contacts have welded after the input circuit has opened. } Open circuit, short circuit or earth fault ( e.g.

PZE X4V 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.

To increase the service life, sufficient spark suppression must be provided on all relay contacts.
