Larko Electronics 30-45/46 Control / Display Module
 |
Larko Electronics 30‑45/46 is a control/display module used in 1980s slide‑gate and motor‑drive applications. Common failure modes include degraded power‑input capacitors, burnt or cracked logic ICs (often the Larko Mark V controller), and frayed ribbon‑cable connections to the gate’s drive electronics. Begin by verifying the 24‑volt DC supply and checking for voltage drops across the module; inspect all surface‑mount components for burn marks or corrosion, and test the ribbon cable continuity and connector contacts. If power is stable, examine the on‑board LED status indicators (if present) and read any diagnostic codes displayed to pinpoint a specific IC fault.[oss-gpt-20b] |
