3500/42M Proximitor*/Seismic Monitor Product Datasheet Bently Nevada* Asset Condition Monitoring Description The 3500/42M Proximitor*/Seismic Monitor is a four-channel monitor that accepts input from proximity and seismic transducers, conditions the signal to provide various vibrations and position measurements, and compares the conditioned signals with user-programmable alarms. You can program each channel using the 3500 Rack Configuration Software to perform the following functions: n Radial vibration n Thrust position n Differential expansion n Eccentricity n REBAM n Acceleration n Velocity n Shaft absolute n Circular acceptance region The monitor channels are programmed in pairs and can perform up to two of the listed functions at a time. For example, Channels 1 and 2 can perform one function while channels 3 and 4 perform another or the same function. The primary purpose of the 3500/42M Proximitor*/Seismic Monitor is to provide the following: n Machinery protection by continuously comparing monitored parameters against configured alarm setpoints to drive alarms n Essential machine information for both operations and maintenance personnel Each channel, depending on configuration, typically conditions its input signal to generate various parameters called static values. You can configure alert setpoints for each active static value and danger setpoints for any two of the active static values. Part Number: 143694-01 Rev. P Page 1 of 20

Use Rack Configuration Software to setalert levels for each value measured bythe monitor and danger setpoints for anytwo of the values measured by themonitor.
Alarms are adjustable from 0 to 100% offull-scale for each measured value.However, when the full-scale rangeexceeds the range of the transducer, therange of the transducer will limit thesetpoint.

REBAM ChannelsThe following graphs show themaximummachine speed allowed for a monitor channel pair configuredfor REBAM. Themaximumspeed depends on the number of rolling elements in the bearing.
The graphs are generated with the following assumptions:
n The rotor lowpass filter corner is set at 3.2 times the shaft speed.n The spike highpass filter corner is set at four times the element pass frequency for the outer race (BPFO).
