Industrial Applications
Turbomachinery Protection
Provide automated shutdown and alarm functions for steam turbines, gas turbines, and compressors when vibration or position exceeds safe limits.
Pump & Motor Monitoring
Trigger alarms or shutdowns when bearing vibration, shaft displacement, or temperature sensors detect abnormal conditions in critical rotating equipment.
Multi-Parameter Monitoring
Monitor up to four different parameters (e.g., radial vibration X-Y, axial position, temperature) with independent setpoints and relay outputs.
Machinery Protection Systems (MPS)
Integrate with distributed control systems (DCS) or programmable logic controllers (PLC) for comprehensive machinery health and safety management.
System Integration
Compatible Input Sources
- 3300 XL Proximitors: Vibration and position sensors
- 3300 XL Monitors: Rack-based monitoring systems
- 3500 Series Monitors: Advanced condition monitoring platforms
- Third-Party Sensors: Any -10V to +10V DC output signal
Typical Configuration
For a turbine monitoring system:
- Channel 1: Radial vibration X-axis (alarm @ 50 µm, danger @ 75 µm)
- Channel 2: Radial vibration Y-axis (alarm @ 50 µm, danger @ 75 µm)
- Channel 3: Axial position (alarm @ 200 µm, danger @ 300 µm)
- Channel 4: Bearing temperature (alarm @ 80°C, danger @ 90°C)
Installation & Setup
Mounting Options
- DIN Rail Mount – Snap module onto standard 35mm DIN rail in control cabinet
- Panel Mount – Use mounting brackets for direct panel installation
- Rack Mount – Install in 19-inch equipment rack with optional adapter
Wiring Guidelines
- Connect input signals from Proximitors or monitors to screw terminals
- Wire relay outputs to DCS/PLC inputs or alarm annunciators
- Provide +24V DC power supply (ensure adequate current capacity)
- Use shielded cables for input signals to minimize noise
- Ground module chassis to equipment ground
Setpoint Adjustment
- Apply known input signal (e.g., 5V DC for 50% of range)
- Adjust alarm setpoint potentiometer until relay trips
- Verify relay operation with LED indicator
- Repeat for danger setpoint (higher threshold)
- Document setpoint values for future reference
Operation & Diagnostics
LED Indicators
| LED | Color | Meaning |
|---|---|---|
| Power | Green | Module powered and operational |
| Ch1-Ch4 Alarm | Yellow | Alarm setpoint exceeded on respective channel |
| Ch1-Ch4 Danger | Red | Danger setpoint exceeded on respective channel |
| Fault | Red (flashing) | Module fault or input signal error |
Relay Logic
- Normal Operation: Relay de-energized, NO contact open, NC contact closed
- Alarm Condition: Relay energizes, NO contact closes, NC contact opens
- Danger Condition: Relay remains energized (same as alarm)
- Latching Mode: Optional configuration to hold relay state until manual reset
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power LED | Power supply failure | Verify +24V DC supply voltage and connections |
| Relay won't trip | Setpoint too high | Adjust setpoint potentiometer, verify input signal |
| False alarms | Electrical noise on input | Use shielded cables, check grounding |
| Relay chattering | Input signal near setpoint | Increase hysteresis or adjust setpoint |
| Fault LED on | Input signal out of range | Check sensor and wiring, verify -10V to +10V range |

FAQ
Q: Can I use this module with non-Bently Nevada sensors?
A: Yes, any sensor or monitor with -10V to +10V DC output is compatible.
Q: What is the difference between alarm and danger setpoints?
A: Alarm is a warning threshold (e.g., 50 µm vibration). Danger is a shutdown threshold (e.g., 75 µm vibration).
Q: Can I configure the relay to latch?
A: Yes, latching mode holds relay state until manual reset. Consult manual for jumper configuration.
Q: What is the maximum relay switching frequency?
A: Electromechanical relays are rated for 100,000 operations. For high-frequency switching, consider solid-state relay modules.
