Ans✓✓✓-If the cross section area A (in cm2) of the piston, the supplied air
pressure pe (in Bar), and the reset force of the spring FR (in N) are given, which of
the following equations is correct to determine the force F (in N) of extension of
the single-acting cylinder shown below.
Ans✓✓✓-The force of retraction F (in N) of a double-acting cylinder when
retracting should be calculated. In which of the following formulas is the
relationship correct mathematically described?

-3/2- way valve
-5/2- way valve
-4/2- way valve
-5/3-way valve
-Quick exhaust valve
-a double solenoid valve position is unchanged....
-a spring-return valve combined with a dominant "ON" latching circuit moves to
the neutral position.... Ans✓✓✓-Which statements about an electropneumatic
control system are correct?In the event of failure of the electrical power supply or
a wire break ...
Two Answers are correct
-a double solenoid valve moves to the neutral position....
-a double solenoid valve position is unchanged....
,-a spring-return valve combined with a dominant "ON" latching circuit moves to
the neutral position....
-a spring-return valve combined with a dominant "OFF" latching circuit moves to
the neutral position....
-a spring-return valve is ever actuated.
-After pushing S1 cylinder 1A retracts immediately. Ans✓✓✓-Which statement
about the operation of the control circuit shown below is correct?
-After pushing S1 cylinder 2A extends immediately.
-After pushing S1 cylinder 1A retracts immediately.
-After pushing S1 cylinder 1A retracts 10s later.
-After pushing S1 cylinder 2A extends 10s later.
-After pushing S1 cylinder 2A retracts 10s later.
-As long as no pushbutton is pressed, the directional control valve remains in the
retracted end position.
-The piston rod of the cylinder is to be advanced if either of the two pushbuttons
S1 or S2 is pressed. Ans✓✓✓-The electrical circuit diagram and the pneumatic
circuit diagram of a control system are shown below. Which statements about the
mode of action are correct? two answers are correct
-As long as no pushbutton is pressed, the directional control valve remains in the
retracted end position.
-If one of the two pushbuttons is pressed, the directional control valve remains in
the retracted end position.
-The piston rod of the cylinder is to be advanced only if both pushbuttons S1 and
S2 are pressed.
,-The piston rod is advanced. When one of the two pushbuttons is released, the
directional control valve switches to the normal position. The piston rod is
retracted.
-The piston rod of the cylinder is to be advanced if either of the two pushbuttons
S1 or S2 is pressed.
-By activating the proximity sensor 1B2. Ans✓✓✓-In the control circuit shown
below, which action will trigger the extension of cylinder 2A?
One Answer is correct
-By activating the proximity sensor 1B1.
-By activating the limit switch 2S2.
-By cylinder 1A leaving the forward end position.
-By activating the limit switch 2S1.
-By activating the proximity sensor 1B2.
-By installation of a quick exhaust valve instead of the one-way flow control valve
1V2 Ans✓✓✓-How can the piston speed of cylinder 1A be greater during
retraction than it is in extension for the control system shown below?One Answer
is correct
-By installation of a quick exhaust valve between valve 1V1 and 1V2
-By installation of a silencer in valve 1V1
-By installation of a flow control valve instead of the one-way flow control valve
1V3
-By installation of an air reservoir between valve 1V3 and cylinder 1A
-By installation of a quick exhaust valve instead of the one-way flow control valve
1V2

the operations of the cylinder 1A and the valve 1V1 correctly in the pneumatic
circuit diagram below?One Answer is correct
-Diagram A
-Diagram B
-Diagram C
-Diagram D
-Diagram E
-Filter, pressure regulating valve, lubricator Ans✓✓✓-Which of the following
components are parts of an air service unit?
-Cooler, filter, accumulator, pressure regulating valve
-Manometer, filter, lubricator, vacuum generator
-Pressure regulating valve, filter, cooler, pressure sensor
-Filter, accumulator, manometer, lubricator
-Filter, pressure regulating valve, lubricator
-It serves to set the forward speed of cylinder 1A. Ans✓✓✓-For the pneumatic
circuit diagram shown below, which task does valve 1V2 do?
-It serves to set the forward speed of cylinder 1A.
-It stops the piston rod of cylinder 1A in the present position, when there is a
sudden drop of pressure.
-It brakes the piston of the cylinder 1A shortly before reaching its stroke end.
-It blows off free, when the pressure rises above the set value.
-It serves for setting the piston force of the cylinder 1A when advancing.
