Bently Nevada 3500/33 Core Function
Dynamic Alarm Drive Logic
AND/OR voting logic combines inputs from:
Alert/danger states (vibration, temperature monitors).
Sensor/rack "Not-OK" faults.
Custom variable combinations across the 3500 system.
Logic is programmed via 3500 Rack Config Software v3.3+, with password/TDI keylock security to prevent tampering.
Operational Visibility & Safety
Per-channel LED indicators:
OK LED (green): Module health.
TX/RX LED: Rack communication activity.
CH Alarm LED (red): Relay-specific alarm state.
SIL compliance: Enforces ≤30 Vdc outputs in functional safety systems to prevent ignition risks.
