Description
Bently Nevada 3300/03-01-00 System Monitor
Configured for centralized rack supervision in Turbine Supervisory Instrumentation (TSI) networks, the Bently Nevada 3300/03-01-00 (base model 3300/03 System Monitor) performs continuous monitoring of rack power supply voltages, manages shared alarm logic, and routes buffered transducer data to external diagnostic interfaces.

Cross-Talk Suppression in Rack-Level Signal Routing
The 3300/03 isolates dynamic signal lines from digital logic lines within the rack backplane to suppress cross-talk between monitoring channels. This separation ensures that transient events on one channel do not propagate false triggers into the shared alarm bus or distort buffered outputs sent to diagnostic equipment.
Frequently Asked Questions
Q: Can the 3300/03 be removed while the rack is powered?
A: No. Always remove rack power before handling the module to prevent backplane damage and ensure correct system initialization upon reinstallation.
Q: Is the 3300/03 compatible with 3500 series racks?
A: No. The 3300/03 is mechanically and electrically incompatible with the 3500 series; rack health functions in 3500 systems are handled by different modules.
Q: Does the module store individual channel alarm setpoints?
A: No. Alarm setpoints are stored in the respective monitoring modules; the 3300/03 consolidates and drives rack-level alarm relays only.
Field Installation Guidelines
Install the 3300/03 exclusively in Slot 1 of a 3300 series rack, immediately adjacent to the power supply. Confirm all rack supply voltages are stable before inserting the module. Route dynamic signal cables away from AC power wiring to reduce electromagnetic coupling. Use proper ESD precautions during handling. Verify correct LED status behavior after installation by performing a rack reset and checking alarm test functionality.
