Bently Nevada 3500/93 System Display
A legacy rack display arrangement for local presentation of machinery-protection values, alarms and module status.
Key Information
3500/93 is the Bently Nevada System Display family documented for the 3500 machinery protection platform. It provides a local operator view of rack measurements and status through a display unit, interface hardware and the configured rack connection.
Because several display and interface part numbers exist within the family, a purchase request should identify the front display, interface module, rear I/O arrangement, mounting style and interconnecting cable.
Functions
- Presents selected machinery-protection measurements and rack status at a local operator position.
- Communicates between the display assembly and its rack interface through the documented display link.
- Supports service observation without changing the underlying monitor-channel configuration.
- Provides a legacy local-display option for installed 3500 systems.

Lifecycle
- Treat 3500/93 as a legacy display family and preserve the complete option set in the maintenance record.

- Keep the rack configuration and display-page documentation available for troubleshooting and migration planning.
FAQ
What must be identified when requesting a 3500/93 replacement?
Provide the display-unit part, interface module, I/O module, cable part and length, mounting method and rack configuration.
Can a 3500/94M display directly replace 3500/93?
Not as a simple module swap; the VGA module, I/O, touch display, cabling and required rack interface must be engineered as a complete change.
Does 3500/93 change protection setpoints?
The system display presents information; protection logic remains in the configured 3500 monitor modules.
What should be tested after servicing 3500/93?
Check communication, every configured page, numeric values, channel labels, alarm state and display readability.
Why is the full 3500/93 option set important?
The family name does not uniquely identify the display, interface, termination, mounting and cable components needed for a compatible replacement.
