Bently Nevada 3500/50M Speed card 3500 system

Additional Notes on 3500/50M Monitor Modules:

1. Enhanced Data Sets:
   • Many channel types offer enhanced data sets, including proportional values depending on the monitor type and configuration.
   • Example: A radial vibration channel provides various proportional values such as gap voltage, 1X/2X filtered amplitude and phase, NOT 1X amplitude, and Smax.
   • ALERT alarm setpoints can be established on each proportional value, and DANGER alarm setpoints can be set on any two proportional values from each channel.
2. 3500/60, /62, and /63 Monitor Types:
   • These monitor types do not provide front-panel buffered output connectors.
3. Differential Expansion:
   • Standard differential expansion capabilities are provided. For ramp differential expansion and complementary input differential expansion, use the 3500/45 Position Monitor.
4. 3500/42M Proportional Outputs:
   • The 3500/42M provides individual 4 to 20 mA proportional outputs for each channel, while the 3500/40M does not provide 4 to 20 mA outputs.
5. Programming and Functionality:
   • Monitor channels are programmed in pairs and can perform up to two functions concurrently.
   • Channels 1 and 2 can perform one function, while channels 3 and 4 may perform another (or the same) function.
6. Velocity and Acceleration Channels:
   • Channels configured for velocity or acceleration provide only direct amplitude.
   • Channels configured for Velocity II or Acceleration II provide 1X amplitude/phase and 2X amplitude/phase in addition to direct amplitude.
7. Vibration Channel Configurations:
   • Vibration channels can be configured for conventional “pie-shaped” acceptance region alarms or circular acceptance regions.
8. Case Expansion Measurements:
   • Only channels 3 and 4 can be used for Case Expansion measurements.
9. 3500/46M Frequency Response:
   • The 3500/46M is suitable for machines with very slow rotational speeds, offering special signal conditioning for specific hydro-specific conditions.
10. 3500/50M Overspeed Protection:
    • Not intended for use in overspeed protection applications. Use the 3500/53 instead.
11. Zero Speed and Reverse Rotation:
    • Both Zero Speed and Reverse Rotation channel types require both channels of the 3500/50 module, making it a single-channel monitor in these configurations.
12. 3500/53 Overspeed Detection:
    • The 3500/53 is a single-channel module intended for use in overspeed detection systems.
13. 3500/60, 3500/61, 3500/62, 3500/64M Variants:
    • Specific details and variations exist between these monitor modules. Refer to the provided documentation or contact the factory for detailed information.
14. 3500/64M Combustor Pressure Pulsation:
    • The 3500/64M is primarily intended for monitoring combustor pressure pulsation instabilities (“humming”) in gas turbines.

Relay Module (3500/50M):

• The 3500/50M Relay Module offers four DPDT relays acting based on alarm conditions within 3500 monitor modules.
• Programming allows various combinations of alarms, providing flexibility from individual channel alerts to complex Boolean expressions.
• By adding relay modules, individual contacts for each channel, alarm type, and group of channels can be achieved for global alarm annunciation.
