PZE X4P INFORMATION This gives advice on applications and provides information on special fea tures. Intended use The unit meets the requirements of EN 6094751, EN 602041 and VDE 01131. The con tact expansion module is used to increase the number of instantaneous safety contacts available on a base unit. Base units are all safety relays with feedback loop monitoring. The category that can be achieved in accordance with EN ISO 138491 depends on the category of the base unit. The contact expansion module may not exceed this. For your safety Only install and commission the unit if you have read and understood these operating instructions and are familiar with the applicable regulations for health and safety at work and accident prevention. Ensure VDE and local regulations are met, especially those relating to safety. Any guarantee is rendered invalid if the housing is opened or unauthorised modifica tions are carried out. Note for overvoltage category III: If voltages higher than low voltage (>50 VAC or >120 VDC) are present on the unit, connected control elements and sensors must have a rated insulation voltage of at least 250 V. Unit features Positiveguided relay outputs: – 4 safety contacts (N/O), instantaneous LED display for: – Switch status channel 1/2 Connection for feedback loop Operation: singlechannel Plugin connection terminals (either springloaded terminal or screw terminal) 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. Operating Manual PZE X4P 1003201EN08...
PZE X4P Earth fault in the input circuit: The output relays deenergise and the safety contacts open. Block diagram/terminal configuration PNOZ X4P PZE X4P CH.1 CH.2 Y1 Y2 43 *Insulation between the nonmarked area and the relay contacts: Basic insulation (over voltage category III), Protective separation (overvoltage category II) Function description The contact expansion module is an addon device without delayon deenergisation, 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 after closing the safety contacts of the base unit: – The supply voltage is present at the input (A1) of the contact expansion module. – Close the safety contacts 1314, 2324, 3334 and 4344. – The LEDs "CH. 1" and "CH. 2" are lit. Functional procedure after opening the safety contacts of the base unit: – There is not supply voltage at input (A1) of the contact expansion module. – Open the safety contacts 1314, 2324, 3334 and 4344. – The LEDs "CH. 1" and "CH. 2" go out. 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. Ensure the unit is mounted securely on a vertical DIN rail (35 mm) by using a fixing ele ment (e.g. retaining bracket or an end angle). If more than 2 units are installed next to each other in the control cabinet, leave a dis tance of at least 6 mm between the units.
PZE X4P Wiring Please note: Information given in the "Technical details [ 9]" must be followed. The outputs 1314, 2324, 3334 and 4344 are safety contacts. To prevent contact welding, a fuse should be connected before the output contacts (see Technical details). Calculation of the max. cable runs l in the input circuit: max lmax / km = max. overall cable resistance (see Technical details) lmax / km = cable resistance/km Use copper wire that can withstand 60/75 °C. Sufficient fuse protection must be provided on all output contacts with capacitive and in ductive loads. Do not switch low currents using contacts that have been used previously with high cur rents.

PZE X4P Operation Status indicators CH.1 Safety contacts of channel 1 are closed. CH.2 Safety contacts of channel 2 are closed. 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.

PZE X4P Contact service life: 2,000,000 cycles Provided the application requires fewer than 2,000,000 cycles, the PFH value (see tech nical 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 contact ors, use freewheel diodes for spark suppression. Remove plugin terminals Procedure: Insert the screwdriver into the housing recess behind the terminal and lever the terminal out. Do not remove the terminals by pulling the cables! Order reference Type Features Connection type Order no.
