Note: In addition to the direct measurement made by the monitor, many channel types provide an enhanced data set consisting of a variety of measured variables that depend on the monitor type and its configuration. For example, radial vibration channels include the basic overall (direct) vibration amplitude as well as gap voltage, 1X filtered amplitude, 1X filtered phase, 2X filtered amplitude, 2X filtered phase, Not 1X amplitude, and Smax. These additional measured variables are provided for each channel, and ALERT alarm setpoints can be established on each variable, as needed. DANGER alarm setpoints can be established on any measured variable value returned from each channel.

H Page 6 of 20 Monitor Module Footnotes 1. Only standard differential expansion capabilities provided. For ramp differential expansion and complementary input differential expansion, use the /45 Position Monitor, instead. 2. The /42M provides individual 4 to 20 mA proportional outputs for each channel. The /40M does NOT provide 4 to 20 mA outputs. 3. The monitor channels are programmed in pairs and can perform up to two of these functions at a time. Channels 1 and 2 can perform one function, while channels 3 and 4 perform another (or the same) function. 4. 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 and bias voltage in addition to direct amplitude. 5. Any vibration channel can be configured for conventional “pie-shaped” acceptance region alarms. When configured for circular acceptance regions, circular (rather than pieshaped) acceptance region alarms can be enabled. Refer to the /42M Operations/Maintenance Manual for additional information, or contact your nearest sales professional. 6. Only channels 3 and 4 can be used for Case Expansion measurements. 7. The /46M provides frequency response characteristics suitable for use on machines with very slow rotational speeds, such as hydraulic turbine/generator sets, which often operate at speeds of 100 RPM or lower. Also, special signal conditioning and tracking filtering is provided, allowing detection of rough load zone operation, shear pin failure, and other hydro-specific conditions. 8. The /50M is not intended for use in overspeed protection applications. Use the 3701/55 Emergency Shutdown (ESD) system, instead. 9. Both Zero Speed and Reverse Rotation channel types require both channels of the /50 module, making it a single-channel monitor when used in these configurations. 10. The /60 and /61 provide identical functions except the /60 does not provide 4 to 20 mA proportional outputs. When these outputs are required, use the /61. 11. The /62 is designed to accept static proportional signals such as 4 to 20 mA, 1 to 5 Vdc, or any static proportional voltage signal between –10 and +10 Vdc. When dynamic signals (i.e., those where waveform information is required) are used, a /40M or /42M can often be programmed as a custom channel type, making the system compatible with virtually any static or dynamic signal from pressure, level, temperature, vibration, flow, position, speed, or other transducers. Consult the factory or your local Bently Nevada sales professional for more information. 12. The /64M is primarily intended for monitoring combustor pressure pulsation instabilities (“humming”) in gas turbines. Note: Analog (4 to 20 mA) and digital (Modbus®) outputs from relay modules are intended for operator annunciation and trending purposes only, as they do not provide the fault tolerance or integrity necessary for highly reliable machinery shutdown purposes. For these applications, the /32M and /33 Relay Modules (described on the following page) should be used.
