Main Functions
- Provides local on‑site manual operation for HKQCS‑MPRC QCS scanner carriage. Operators control scanner movement directly at scanner frame without cabinet access.
- Translates membrane keypad actuation into matrix signals and transmits commands to scanner main controller via ribbon cable.
- Works cooperatively with other MPRC‑HKQCS system hardware including 086345‑004 backplane, 086339‑001 sensor daughter‑board, and 086318 series SRAM memory boards.
- End‑of‑life component, supplied only for legacy paper mill QCS system maintenance.
Typical Applications
- Local operator interface replacement for ABB MPRC‑HKQCS scanning frame in paper‑machine quality control systems.
- Spare‑part change‑out for units suffering membrane aging, trace corrosion or keypad dead‑key faults.

Important Notes
- Exclusively compatible with HKQCS / MPRC scanner assembly. Not a general‑purpose PLC/DCS module or touch‑screen HMI. Many third‑party vendors misclassify this component.
- Subject to moisture‑related degradation in humid paper‑mill environments. Avoid excessive pulling force on flat ribbon cable during service.
- Electrostatic‑sensitive assembly. ESD protection must be implemented during handling and replacement.
- After replacement, full functional verification of all local keypad commands is required before returning system to production.
- Specify full part number 100472‑012 for spare‑part procurement.
