Frequently Asked Questions (FAQ)
Q1: What types of sensors are compatible with the 3500/42M module?
A1: It supports proximity probes, velocity transducers (Velomitor), and acceleration sensors.
Q2: Can the monitor operate with mixed sensor types on different channels?
A2: Yes, channels are configured in pairs and can support different sensor types in different pairs.
Q3: What filtering options are available for signal processing?
A3: Filters include high-pass, low-pass, notch (Not 1X), 1X/2X vector, and band-pass for REBAM.
Q4: Is the monitor compliant for hazardous areas?
A4: Yes, it holds approvals for Class I, Division 2 and ATEX Zone 2 installations, depending on the I/O module used.
Q5: What static values can be monitored?
A5: The monitor supports static values such as direct vibration, gap, 1X/2X amplitude and phase, Smax, REBAM spike, thrust position, and more.
Q6: Does it support alarm time delays?
A6: Yes, both alert and danger alarms have configurable delay settings from 0.1 to 400 seconds depending on the function.
Q7: How is data output managed?
A7: Each channel provides a 4–20 mA output and coaxial buffered outputs for transducer signals.
Q8: What is REBAM and how is it used in this module?
A8: REBAM is used for rolling element bearing monitoring, with user-programmable frequency bands and filters for spike, rotor, and element analysis.
Q9: Can this module detect shaft absolute vibration?
A9: Yes, it supports shaft absolute vibration and velocity via specialized I/O modules.
Q10: What is the required software for configuration?
A10: Configuration is done using 3500/01 software (v2.50+), and DM2000 for REBAM and advanced diagnostics.
