Abstract
A safety system for a moving walkway having a continuous loop of steps driven by a drive system and missing step detector adapted to detect a missing step from the loop of steps. The safety system comprises: an interrupt unit adapted to control the drive system to disable automatic movement of the loop of steps upon detection of a predetermined event and adapted to subsequently control the drive system to enable automatic movement of the loop of steps only after a safety procedure has been completed without a missing step being detected by the missing step detector. The safety procedure comprises causing a step to traverse an entire loop under manual control of the drive system.
