When can the Door Enabler be activated in Bypass mode?

The activation of the Door Enabler in Bypass mode is specifically permitted only when the train has come to a complete stop at the proper car marker. This requirement ensures the safety of passengers and crew by preventing doors from being opened while the train is in motion, which could pose significant hazards.

By requiring that the train stops at the designated marker, the system aims to ensure that boarding and alighting can occur safely, and that passengers are aware of their environment as they enter or exit the train. This protocol is crucial, especially in ensuring that the train operates within safety regulations and minimizes the risk of accidents related to door operations.

The other contexts in which the Door Enabler could be activated, such as when the train is in motion or during emergencies, are not part of the standard operating procedures since these scenarios do not uphold the necessary safety measures associated with train doors. Therefore, it is clear why the activation of the Door Enabler is limited to when the train is completely still and properly aligned.
