I sent the arm and controller labels, not the interface's reference. That's now added with the mismatched guide page. No wiring changes here.

Ask their technical contact to confirm the supplied combination as well as the document revision. A different PDF alone does not establish that the hardware belongs together.

They've sent another guide, still without mapping it to our interface reference. I've pointed out the connection drawing remains different. Setup is still held.

Who is reviewing that discrepancy technically? I'd ask for a named person to answer the specific marked page, not another general request that lets sales send the same manual again.
