How do I identify a Blue Light elevator car-top board for replacement?

Ask Time: 2024-03-21
Answer
Photograph the full board label, revision markings, connectors and controller identification. Include the board's installed function and any software label. The Blue Light category includes different assemblies, so a brand description alone is insufficient to select the correct replacement.

Are Blue Light command boards and car-top boards interchangeable?
They should not be treated as interchangeable. Their assigned inputs, outputs and software functions may differ even when connectors look similar. Use the exact part code, revision and circuit position to verify the required board against the controller documentation.
