Q1: What is the primary function of the 3500/40M-01-00?
It is a 4-channel Proximitor Monitor that accepts input from Bently Nevada proximity transducers, conditions the signals to provide various vibration and position measurements, and compares the conditioned signals with user-programmable alarms. Each channel can be programmed to perform radial vibration, thrust position, differential expansion, eccentricity, or REBAM monitoring.
Q2: What is the difference between 176449-01 and 125680-01?
The 176449-01 is the Proximitor Monitor (main card) that processes the transducer signals and generates alarms. The 125680-01 is the Proximitor I/O Module that provides the physical terminal connections for field wiring. Both are required together to form a complete 3500/40M-01-00 monitoring channel.
Q3: How are the channels configured?
The monitor channels are configured in pairs. Channels 1 and 2 can perform one function, while channels 3 and 4 can perform another (or the same) function. This allows a single module to simultaneously monitor two different measurement types (e.g., radial vibration on CH1/2 and thrust position on CH3/4).
Q4: What is the Bypass LED used for?
The Bypass LED indicates when the module is in Bypass Mode. Bypass mode is used during maintenance or testing to temporarily disable alarm and trip functions while the machine continues to operate, preventing false trips during sensor replacement or calibration.
Q5: What are the common applications for the 3500/40M?
It is widely used for steam and gas turbines, centrifugal compressors, electric motors, hydro-turbines, and other critical rotating equipment. It provides continuous machine protection by comparing real-time vibration and position values against programmable alarm and danger setpoints, driving shutdown logic when thresholds are exceeded.
