PURPOSE:  The purpose of this laboratory exercise is to introduce the control of fluid power systems using relay ladder logic.
                      A follow up lab on control systems will be conducted on PLC control when pneumatic systems are covered.

OBJECTIVE:  After completing this laboratory exercise, you should be able to do the following:

        1.  Write a control sequence matrix describing the conditions and restriction of operations;
        2.   Simulate the circuit in Automation Studio and document the step-by-step operation;
        3.   Write documentation for each "rung" describing the overall function of the rung;
        4.   Label all electrical inputs and outputs by name and function;
        5.   Write a detailed operational procedure for the system.
 

PROCEDURE:

        1.  Develope a control matrix for the system shown below;
        2.  Draw the following fluid circuit in Automation Studio;
        3.  Draw the electrical control circuit using U.S. ladder logic procedures;
        4.  Simulate the circuit to verify the operation of the clamp and work sequence;
        5.  Simulate the circuit in Step-By-Step mode and note the change of states of electrical components;
        6.  Write a heading for each rung, indicating the control function of each;
        7.  Label each electrical component in the ladder diagram;
        8.  Describe the function within each rung;
        9.  Write a detailed operational sequence for the system.  Provide a detailed, step by step description
              of the electrical control circuit, rung by rung.
        10. Submit a formal written report by next class period.
