Before you start please read the following instructions carefully.

1. This assignment forms part of the formal assessment for this module. If you fail to reach the required standard for the assignment then you will be allowed to resubmit but a resubmission will only be eligible for a Pass grade, not a Merit or Distinction.

You should therefore not submit the assignment until you are reasonably sure that you have completed it successfully. Seek your tutor's advice if unsure.

2. Ensure that you indicate the number of the question you are answering.

3. Make a copy of your answers before submitting the assignment.

4. Complete all details on the front page of this TMA and return it with the completed assignment including supporting calculations where appropriate. The preferred submission is via your TUOL(E) Blackboard account:

5. Your tutor's comments on the assignment will be posted on Blackboard

FIGURE 1 shows a pneumatic circuit diagram used for air supply and exhaust in an automatic control system.

(a) Name all symbols (including pipelines) used in the system.
(b) Number the ports of each DCV.
(c) Classify the sections of the components in the circuit.
(d) State how the system works.
(e) State the functions of valves and .

2. FIGURE 2 shows a pneumatic circuit in which four actuators are controlled.

(a) State the sequence in which the cylinders operate on the operation of the start valve.

(b) Show, with the aid of a schematic diagram, how an electronic controller could be included in the circuit to control the sequence of cylinder operations.

3. Design and draw a circuit using the cascade system to operate two cylinders (A and B) which, on the operation of a start valve, produces the sequence A - B + B - A+. The cylinders should park in the positions B - A + when the start switch is in the ‘off' position.

4. Modify the circuit designed for question 3 to provide an emergency stop which will park both cylinders in the extended position (i.e. A + B +).

5. Modify the circuit designed for question 3 to provide a fail safe. The fail safe should:

(a) act in the event of a reduced pressure at inlet to the group selecting valve

(b) park the cylinders in the retracted position.

6. FIGURE 3 shows a hydraulic circuit.

(a) State the name and purpose of the components shown in the circuit diagram.

(b) Explain the operation of this circuit.

(c) Explain the limitations of this circuit in terms of ‘speed control'.

7. Modify the design of the circuit shown in FIGURE 3 and draw a circuit diagram to provide rotary actuation in both directions using a single direction pump (to replace the bi-directional pump) and providing a means of preventing over-speeding in the case of an overhauling load in both directions.
