transition conditions. Which of the transition conditions
represented by Boolean expressions, logic symbols and standardized
circuit symbols are correct? Answer: Solution B, Solution E
◉ 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
