FAQ
Q1: What type / sensors can the 3500/40 accept?
A1: It accepts proximity transducer inputs from 1 to 4 channels.
Q2: Can the monitor measure multiple parameters at once?
A2: Yes, channels can be configured in pairs to measure up to two different parameters simultaneously.
Q3: What is the purpose / REBAM functionality?
A3: REBAM detects rolling element bearing faults through high-frequency vibration analysis.
Q4: How are alarm setpoints configured?
A4: Alarm limits are set using the 3500 Rack Configuration S/tware.
Q5: Does it support hazardous area installation?
A5: Yes, with appropriate I/O module options it is certified for ATEX, IECEx, CSA, and cNRTLus.
Q6: What is the role / the front panel LEDs?
A6: LEDs indicate OK status, communication activity, and bypass mode.
Q7: Can it be used in marine applications?
A7: Yes, it meets ABS and DNV GL maritime standards.
Q8: What is the typical operating temperature range?
A8: –30°C to +65°C (varies with I/O module type).
Q9: How accurate is the vibration measurement?
A9: Typically ±0.33% / full scale, ±1% maximum.
Q10: Is it compatible with older 3500 Series racks?
A10: Yes, provided firmware and s/tware meet the minimum required versions.
