Question 1: During a high-voltage hipot test, what happens if the insulation fails?

Which action should you take?

Choose only one option

It will trip the overload protection circuit

It will cause excessive heating of the insulation material

It will cause the voltage level to drop automatically

It will create an electrical arc or leakage current

Question 2: When designing a PLC program to handle multiple analog inputs, what is the most efficient way to handle scaling?

Which action should you take?

Choose only one option

Using comparison functions to set the desired output range

Using a timer to handle input signal variations

Using counters to detect input thresholds

Using a scaling function to convert analog input ranges to a standard range

Question 3: If the signal from a field sensor in a closed-loop system is noisy, what is the first action to take in troubleshooting?

Which action should you take?

Choose only one option

Inspect the sensor wiring for proper shielding and grounding

Verify the controller settings for noise filtering

Replace the sensor immediately
