Bently Nevada 3500/94 145988-01 VGA Display Main Module
The front main module used in the earlier 3500/94 VGA display architecture.
Key Information
3500/94 145988-01 identifies the main module for the legacy Bently Nevada 3500/94 VGA display system. It belongs to the earlier display generation and should not be confused with current 3500/94M main and I/O module part numbers.
A service request must document the rear I/O module, touch display, cable set, rack interface and software baseline because those companion components determine whether the display system can be restored without redesign.
Functions
- Processes rack display information for presentation on the associated VGA operator screen.
- Works with the matched rear I/O module and display cabling of the legacy 3500/94 architecture.
- Presents configured channel values, status and alarm information for operator review.
- Occupies the front rack position aligned with its companion I/O hardware.

Installation
- Record the existing front module, rear I/O, display and every cable part number before disturbing 3500/94 145988-01.
- Confirm the rack slot and communication arrangement against the controlled system drawing.
- Keep display maintenance separate from changes to machinery-protection setpoints and monitor configuration.
- Verify video, touch response, channel pages and alarm indication after the hardware exchange.
Lifecycle
- Preserve 3500/94 145988-01 as a complete legacy display-system record rather than an isolated board number.
- Do not substitute a 3500/94M module without reviewing I/O, display, cabling, firmware and TDI requirements.
- Plan display modernization independently from immediate repair so the protection rack remains controlled and documented.
FAQ
Is 3500/94 145988-01 the same as a 3500/94M main module?
No. The 3500/94M uses different current spare-part numbers and has its own firmware, I/O and display requirements.
What companion parts must be identified with 3500/94 145988-01?
Provide the rear I/O number, display model, cable numbers, mounting arrangement and rack/software baseline.
Can only the 3500/94 145988-01 front module be changed?
It can be replaced only when the supplied module is compatible with the existing rear I/O, display and firmware environment.
Does replacing 3500/94 145988-01 alter protection logic?
The display module presents rack information; protection settings remain in the monitoring modules, but the display functions still require verification.
What acceptance checks follow a 3500/94 145988-01 replacement?
Confirm boot status, video quality, touch operation, rack communication, all configured pages and alarm/OK indication.
