In the inspection mode, which switches will be bypassed?

In inspection mode, the purpose is to conduct a thorough check on the escalator's operation and safety features without fully engaging all the safety mechanisms that are typically active during regular operation. Bypassing certain switches allows the technician to identify issues or assess performance in a controlled manner.

The correct choice identifies that the handrail speed switch, the two-floor plate switches, and the two missing step switches are bypassed during the inspection mode. This is important because it allows the inspection to proceed without the usual automatic stops that would occur if the escalator was in a normal operational state. By allowing these switches to be bypassed, inspectors can better observe the escalator’s function and assess performance while eliminating potential interruptions that would inhibit their assessment.

The handrail speed switch is critical because it ensures the handrail operates in sync with the escalator steps. Bypassing this allows inspection of the overall system function without unintended stops. The two-floor plate switches and the missing step switches are also safety features designed to stop the escalator in case of issues. By bypassing these in inspection mode, inspectors can simulate conditions and assess the escalator's performance more effectively.

Understanding which specific switches are bypassed is crucial for those working with escalator systems, as it directly
