A pneumatic valve is defined as a 5/2 - way valve. What does the
number 5 mean in this definition?
-The valve has a port for the exhaust.
-The valve has 5 switching positions.
-The valve has a neutral position and 4 other switching positions.
-The valve has 5 ports.
-The valve has 5 ports for work conductions.
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.
,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.
For the extension of the cylinder shown below, a force of F = 300 N is
needed. If the frictional force is 10 % of F, how high must the applied air
pressure pe be to move the slide?
-pe = 2.75 bar
-pe = 4.5 bar
-pe = 5.5 bar
-pe = 6.5 bar
Which statements about the component shown below are correct?
,Two Answers are correct
-The air pressure at X acts on a cylinder surface. If the force exerted
exceeds the spring force of the return spring, the piston moves and
operates the contact set.
-An electronic pressure sensor with digital output signal is shown.
Instead of actuating mechanical contacts, the output is switched
electronically.
-Y is a knob for adjusting the spring force of the return spring.
-When the piston moves to operate the contact set the connection
between 2 and 4 is closed.
-Y is a pushbutton to check the functionality of the pressure switch.
The text below represents the logical association between transition
conditions. Which of the transition conditions represented by Boolean
expressions, logic symbols and standardized circuit symbols are
correct?
Two Answers are correct
-Solution A
-Solution B
-Solution C
-Solution D
, -Solution E
Which component is represented symbolically?
2/2- way valve
3/2- way valve
Shuttle Valve
Vacuum Generator
Quick exhaust valve
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.
For the pneumatic circuit diagram shown below, which task does valve
1V2 do?
-It serves to set the forward speed of cylinder 1A.
