How do I identify the correct STEP elevator control board replacement?

Ask Time: 2026-07-28
Answer
Record the complete board code, hardware revision, software label and installed controller model. Include its function and connector photos. STEP boards used for car calls, car-top control or group control should be identified separately, even when they share a similar appearance.

Derived Questions

Why is a STEP car call board not registering button presses?
Possible causes include power loss, button wiring, addressing or communication problems as well as board damage. Record board indicators and controller fault information. A technician should verify the supported configuration and connected inputs before concluding that the board itself has failed.

What should a distributor request when buying STEP spare boards?
Ask for the full board identification, declared supply condition, included firmware or configuration and traceability information. Keep an approved fleet list of supported controller versions. Confirm whether setup, licensing or a service tool is needed before a spare can be used.

Can I replace a STEP car-top board without changing the main controller?
That depends on the supported board revision, communication arrangement and controller software. Confirm the replacement pairing and any address or configuration requirements. Preserve the original wiring and settings documentation so the technician can commission the new board correctly.

Which handheld operator do I need for a STEP elevator controller?
Specify the controller series and software information, then confirm the supported service tool and connection cable. A handheld unit from the same brand is not automatically suitable for every generation. Ask which functions and parameter access are supported for the exact controller.

Can a STEP group control board be added to independent elevators?
Only if the individual controllers and software support the proposed group system. The project requires review of communication wiring, dispatch functions and configuration. Request a system-level proposal for the identified controllers rather than purchasing a group board as a standalone upgrade.
