Question 93Electricity & Electronics - Assistant Engineer

The correct answer is A) Master switch contacts "4", "5", and "6" close. When the 'third point hoist' function is selected on the winch hoist controller, the master switch contacts "4", "5", and "6" will close to enable that specific control function. This is the correct operation as per the winch hoist controller's design and functionality. The other answer choices are incorrect because they do not accurately describe the electrical connections and contactor behavior when the 'third point hoist' is selected. Choices B, C, and D describe different contact closures or contactor operations that are not associated with the 'third point hoist' selection on this particular winch hoist controller.
