What does a flashing door out of order light indicate?

The indication of a flashing door out of order light signifies that there is a fault within the door system itself. This fault could arise from various issues, such as mechanical failures, electrical faults, or sensor malfunctions. The flashing light serves as an alert to operators that the door is not functioning as intended, prompting immediate attention to rectify the problem before it's safe to operate the door again.

The distinction between a general fault and other options is crucial. A power failure in the door system would typically result in no light or a different type of signal, rather than a consistent flashing. Similarly, an emergency brake application generally activates a different set of indicators specific to that safety feature. Lastly, a cab safety check needed message would not indicate a failing door system directly; it would pertain more to operational procedures rather than signaling a mechanical fault in the door itself. Understanding these specifics helps in accurately diagnosing and addressing issues within the system.
