BThe 'MS 2' contacts are used to select for 'first point' hoisting and lowering.
CThe 'MS 2' contacts are not used in this particular application.
DThe "MS 2' contacts are used for resetting the undervoltage (UV) contactor.
AI Explanation
The correct answer is C) The 'MS 2' contacts are not used in this particular application. The illustration EL-0102 does not show any 'MS 2' contacts being used in the hoist controller circuit. The 'MS 2' contacts are likely intended for a different function or application not depicted in this specific diagram. Without more context about the overall system, there is no evidence that the 'MS 2' contacts serve any purpose in this particular hoist controller circuit. Therefore, option C is the correct answer, as the 'MS 2' contacts are not utilized in this application as shown in the illustration.
