◉ Which of the following displacement step diagrams show the
operations of the cylinder 1A and the valve 1V1 correctly in the
pneumatic circuit diagram below? Answer: Diagram A
◉ For the pneumatic circuit diagram shown below, which task does
valve 1V2 do? Answer: It serves to set the forward speed of cylinder 1A.
◉ Which of the following output voltages based on the float position of
an automotive fuel level sensor, as shown below, is correct? Answer:
10V 5V 0V
,◉ An electrical power supply is shown below. Which statements about
the functionality ofthe circuit are correct? Answer: **NOT The diode
rectifier changes the AC voltage to a pulsating full-wave DC voltagethat
is smoothed by the capacitor C1. AND If the fuse is blown, the AC
voltage between point 2 and 3 will be 230 V.**
◉ In a testing application inspection cylinder 2A has to distinguish
between lower and upper half cubes, as shown below. Which statements
about the mode of operation are correct? Answer: **NOT In Figure a,
the part is recognized as a lower half cube. Inspection cylinder 2A has
reached the extended end position, which is detected by sensor 2B1.
AND In Figure b, the part is recognized as an upper half cube.
Inspection cylinder 2A has reached the extended end position, which is
detected by sensor 2B1.**
◉ The result from a "Teach in procedure" of an ultrasonic sensor with
analog output is shown below. Which statements about the operation of
the sensor are correct? Answer: The output voltage when an object is
detected at a distance of 55 mm is ˜ 5 V., The voltage at the output alters
by 10 V / 50 mm = 0.2 V / mm, starting from the zero point.
◉ The switching frequency of a power electronic for a DC machine is
set to 2 kHz. This could cause: Answer: Annoying noise.
◉ Picture A shows an electrical circuit with a motor. Part #3 compares
current I1 and I2. If the current I1 is not I2 equal part #3 breaks the
circuit. Which safety function does circuit element #3 accomplish?
, Answer: Protects the operator from current flow through the machine
housing
◉ The internals of an automotive gearbox are shown below. What
condition must hold true if any two gears of the type shown are to mesh
properly? Answer: The teeth of both gears must be the same size., The
shafts must be parallel
◉ The builder of the automotive racing engine shown in the picture
decided to use socket head cap screws to attach the valve covers. What is
the pitch of the screws used? Answer: 2mm
◉ Which components are used for energy transport between different
machine units of a system? Answer: Timing Belts, Power Screws
◉ The Boolean equation for the logic represented in the ladder diagram
shown below can be expressed as ... Answer: Y = (A) + (C ) + (BC)
◉ The move instruction copies data from ... Answer: ... a source byte to
a destination byte.
◉ The symbol shown below in the ladder diagram ... (looks like --| |--)
Answer: ... can be thought of as a contact that is usually opened.
