Q1: What is the primary function of the 3500/42M-09-00?
It is a 4-channel Proximitor/Seismic Monitor that accepts input from proximity, velocity, and acceleration transducers. It conditions the signals to provide vibration and position measurements and compares them against user-programmable alarm thresholds. The -09-00 configuration specifically uses the 140471-01 Prox/Velom I/O Module for applications involving proximity probes, accelerometers, and Velomitor sensors.
Q2: What is the difference between the -09-00 and -01-00 configurations?
The primary difference is the I/O module type. The -09-00 uses the 140471-01 Prox/Velom I/O Module, optimized for Prox/Accel/Velomitor sensor combinations. The -01-00 uses the 128229-01 Prox/Seismic I/O Module, designed for standard proximity and seismic (velocity/acceleration) inputs.
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: Does the 3500/42M-09-00 support TMR applications?
No. This specific configuration (-09-00) is a standard (non-TMR) monitor. For Triple Modular Redundant applications, the TMR Proximitor I/O Module (149716-01) must be used with appropriate TMR rack configuration and the 3500/34 TMR Relay Module .
Q5: What is the difference between the 3500/42M and the 3500/40M?
The 3500/42M accepts both proximity and seismic (velocity/acceleration) inputs, making it versatile for applications requiring casing vibration or shaft absolute measurements. The 3500/40M is designed for proximity transducer inputs only, used primarily for radial vibration and thrust position.
