Q1: What is the difference between the 3500/42M and the standard 3500/42?
The 3500/42M is the enhanced version featuring advanced signal processing algorithms, more comprehensive self-diagnostics (including probe open/short detection), and superior noise immunity for high-interference environments . It is the preferred choice for critical machinery where measurement accuracy directly impacts protection reliability.
Q2: What does the "-09" and "-00" suffix mean in the model number?
The -09 indicates the I/O module type: 128229-01 Prox/Velom I/O Module with internal terminations . The -00 indicates no hazardous area agency approvals (standard version) . For hazardous areas, the -01 or -05 suffix variants are required.
Q3: What transducers can be connected to this module?
The 3500/42M accepts inputs from proximity probes (3300 XL series), velocity transducers (Velomitor), and acceleration transducers . Each of the 4 channels can be independently configured for the appropriate transducer type.
Q4: What is the primary application difference between 3500/42M and 3500/70M?
The 3500/42M is designed for rotating machinery (turbines, compressors, pumps) to monitor radial vibration and shaft position . The 3500/70M is specialized for reciprocating machinery (reciprocating compressors, large diesel engines) to analyze impact events, rod drop, and cylinder pressure .
Q5: What does a "Not OK" status on a channel indicate?
A "Not OK" status typically indicates a transducer fault, cable break, or supply voltage drop. Check the -24 VDC power rail at the I/O module first using a high-impedance multimeter . Other common causes include loose connections, probe gap out of range, or a failed Proximitor sensor.
