Where should you check if the Step Level switch on an escalator has been activated?

To determine whether the Step Level switch on an escalator has been activated, it's essential to check both the top and bottom sections of the escalator. The Step Level switch is a safety feature designed to ensure that the escalator operates correctly, maintaining the proper alignment of the steps as they move between the ground and upper levels.

When an escalator is in operation, the steps must remain level with the landing platforms at both ends. If there's a discrepancy, the Step Level switch will activate, potentially halting the escalator to prevent accidents or injuries. Checking both ends helps identify any issues with the escalator's alignment that may have caused the switch to activate. This comprehensive inspection ensures safety and confirms that the escalator is functioning correctly at all critical points of operation.

In contrast, checking only one end (whether at the bottom, top, or middle) may miss detection of any safety concerns arising from the other section. Since both ends are critical to the escalator’s proper operation, a complete assessment at both the top and bottom is necessary for thorough safety checks.
