Which UR5e fixture input explains this wait with an empty receiver?

Author identified the input. Retained trace shows false while the receiver is empty. Fixture identity matches their instructions.

Have maintenance check the actual sensing and signal path. The empty receiver narrows the question, but it does not identify which part of that path is wrong.

Does the covering maintainer have the same trace and input reference?

Yes, Luis. Both maintainers have it. Inspection found the sensor bracket displaced from its specified position.

Was the mounting itself damaged or loose? Restoring the position needs to include why it moved.

Fastener loose. Maintenance restored the mounting and checked confirmation at the intended position. Full sequence verification still due.

Verification found another intermittent drop during fixture exchange. Ticket stays open; the static repair check did not cover it.

Retain that new exchange occurrence separately from the first stop and send it with the repair finding. Useful to know the repair improved one check without claiming it explained every interruption.
