Core Functions

1. Rack‑to‑display data bridge: Collect full‑rack channel measurements, alarm status, fault codes and event history, transmit data to 3500/93 local LCD display for on‑site operator viewing.
2. Dual‑display support: Single rack can install two 135799‑01 DIM modules to drive two independent local display panels.
3. Protection‑safety isolation: DIM hardware failure will not impact hardware trip logic of all monitor modules; machinery‑protection function remains intact.
4. Self‑diagnosis: Detect backplane communication fault, serial‑link fault to display unit; report module hardware fault to rack‑system log.

Installation, Replacement & Critical Warnings

1. Supports hot‑swap; local‑display operator interface is lost during plug‑pull, but machinery‑protection trip function is unaffected.
2. Compatibility warning: ‑ Must use matched rear‑I/O 135813‑01; cannot interchange main‑board / rear‑I/O with 135785‑01 / 135785‑02 DIM modules. ‑ Front‑face‑mount display application requires DIM install in slot‑15 (right‑most slot) of full‑size rack; remote‑mount display has no slot‑15 restriction. ‑ Maximum two DIM modules per rack for dual‑display 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 serial communication link to display unit, confirm real‑time data and alarm indication on local display panel.

4. Common failure mode: Serial‑interface circuit damage, component aging; serial cable fault will cause local‑display blank / no‑data, will not trigger machinery‑protection trip.
