    PSWZ X1P Introduction Validity of documentation This documentation is valid for the product PSWZ X1P. It is valid until new documentation is published. This operating manual explains the function and operation, describes the installation and provides guidelines on how to connect the product.

  • Page 6: Safety

    Safety Intended use The PSWZ X1P is used for safe standstill monitoring. The unit is designed for use with Standstill monitoring at plants with dangerous machine parts or tools in safety circuits in accordance with VDE 0113-1 and EN 60204-1 Standstill is only detected on power-free measuring circuits.

  • Page 7: Use Of Qualified Personnel

    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. Operating Manual PSWZ X1P 21005-EN-11...

  • Page 8: Unit Features

    The standstill monitor prevents the plant from being enabled in the following cases: – Power supply failure – Component failure – Measuring circuits are open circuit – Coil defect/open circuit Operating Manual PSWZ X1P 21005-EN-11...

  • Page 9: Block Diagram/Terminal Configuration

    If the voltage falls below the set response value (standstill threshold), the PSWZ X1P enables the monitored plant. When used with frequency converters, the PSWZ X1P cannot detect standstill until the con- troller inhibit has been switched off.

  • Page 10: Operating Modes

    If the simultaneity requirement is exceeded, the "FAULT" LED is lit and on the semicon- ductor output Y35 there is a High signal. The PSWZ X1P does not enable the monitored plant. The fault is reset by applying a High signal and then a Low signal at the reset input.

  • Page 11: Timing Diagram

    Outputs 13-14, 23-24 are safety contacts, the output 41-42 is an auxiliary contact (e.g. for display). Auxiliary contact 41-42 should not be used for safety circuits! To prevent contact welding, a fuse should be connected before the output contacts (see Technical details [ 18]). Operating Manual PSWZ X1P | 11 21005-EN-11...
  • Page 12 When used with converters: Please comply with the information regarding installation and wiring in the documentation of the converter. Use screened cable for the wiring between the PSWZ X1P and the motor. Connect the cable screening on the motor. Protect the measuring circuits according to the conductor cross section.
