NPN switches should be used When the electrical circuit is grounded by the PLC When switching speed is not a concern When the PLC provides electrical power O For all vacuum applications

Answer 1

NPN switches should be used When the electrical circuit is grounded by the PLC O When switching speed is not a concern When the PLC provides electrical power O For all vacuum applications A partial blockage in the vacuum generator will result in O High vacuum pressure Low vacuum pressure Noisy operation No vacuum pressure A crack in the vacuum generator's muffler may result in Noisy operation O An increase in vacuum pressure A decrease in vacuum pressure Slower actuator speed Dent

A vacuum switch converts a sensed pressure into a(n) O Vacuum reading corresponding vacuum pressure O Mechanical force Electrical signal A continuous input to the PLC from the vacuum switch may be the result of O A short in the electrical wiring O Broken internal components An open in the electrical wiring O Debris in the system To set the set point of a vacuum switch, the vacuum line leading to the vacuum cup must be Disconnected O Opened Josed O Properly sized An uneven part surface can cause a vacuum cup to lose its seal because There is not enough rubber in contact with the part to maintain its grip It allows air to enter the cup reducing the amount of vacuum O It creates too large of an effective surface area It reduces the amount of vacuum created by the vacuum generator

An oversized vacuum cup a thin part. C Can more effectively lift O May damage Cannot create sufficient vacuum to lift O Cannot create a seal on The of a vacuum switch deforms based on the amount of pressure applied to it O Gasket O Piston O Lead Ciaphragm

The correct answers are marked with green. I am pretty sure of these answers. Please dear thumpsup for the answer. Thank you.
