    1.7 Scope This manual describes the Special Module 750-645 2AI/2DO VIB VRMS/SPM Multi of the modular WAGO-I/O-SYSTEM 750. Handling, assembly and start-up are described in the manual of the Fieldbus Coupler. Therefore this documentation is valid only in the connection with the appropriate manual.

  • Page 11: Condition Monitoring

    The continuous registration of the machine health condition via the fieldbus permits an early analysis and reaction prior to the actual occurrence of damages. For this purpose, WAGO offers the WAGO-I/O-SYSTEM function modules for recording and processing of the relevant parameters, such as current, temperature, standard signals and machine vibrations.

    Every additional material transition dampens and/or reflects the signal to be measured. The signal path should have one material transition maximum, between bearing and bearing enclosure.

  • Page 22 For this reason, measurements should be taken within the load zone of the bearing, if possible. The load zone is defined by the emission window (see also illustration below). The ideal situation is the measuring point right in the emission window. WAGO-I/O-SYSTEM 750 I/O-Modules...
  • Page 23 This area is defined as emission window. Outside an emission window, weakened and reflected signals are measured. These measurements permit trend tracking and comparisons, but will not provide for accurate statements to the lubrication state or possible bearing damages. WAGO-I/O-SYSTEM 750 I/O-Modules...
