Core Functions

1. VGA graphic data output: Output full‑rack channel measurements, alarm lists, system event logs, graphical rack overview to external VGA touch‑screen monitor.
2. Custom display page function: Supports up to nine user‑configurable custom display screens for grouping machinery‑monitoring parameters on‑site.
3. Touch‑screen operation support: Receives touch operation commands from external touch‑monitor for local page switching and alarm browsing.
4. Dual‑monitor expansion: Single rack can install two 3500/94 modules to drive two independent VGA touch displays.
5. Protection‑safety isolation: Module hardware failure will not impact hardware trip logic of all monitor modules; machinery‑protection function remains intact.
6. Self‑diagnosis: Detect backplane communication fault, VGA/touch‑link fault; report module hardware fault to rack‑system log.

Installation, Replacement & Critical Warnings

1. Supports hot‑swap; VGA graphic display function is lost during plug‑pull, but machinery‑protection trip function is unaffected.
2. Compatibility warning: ‑ Must use matched rear‑I/O 147663‑01; cannot interchange main‑board / rear‑I/O with 3500/93 DIM series modules. ‑ Maximum two 3500/94 modules per rack for dual‑monitor configuration; must cooperate with 3500/22M TDI module. ‑ Verify rack firmware and configuration‑software version compatibility before replacement.
3. After replacement, check OK LED status; download rack configuration project, verify VGA video output, touch‑screen response, confirm real‑time data, alarm indication and custom display‑page function.

4. Common failure mode: Video output circuit damage, component aging; VGA/touch cable fault will cause screen blank or touch failure, will not trigger machinery‑protection trip.
