Inputs and Outputs For each of the following OUTPUTS design a Boolean expression. MOTOR UP (MUP) MOTOR DOWN (MDN) OPEN PILOT LIGHT (POP) SHUT PILOT LIGHT (PSH) AJAR PILOT LIGHT (PAJ) INPUTS OPEN Momentary Contact Pushbutton (OP) CLOSE Momentary Contact Pushbutton (CL) STOP Momentary Contact Pushbutton (ST) UPPER Limit Switch (LS1) LOWER Limit Switch (LS2) Exercise 1 In this exercise we want you to apply your knowledge of Relay controls and boolean to design a program which will control an overhead door. The Door System includes a Reversible Motor, a pair of Limit Switches and a Operator Control Panel. The system you create will monitor and control this equipment while adhering to the following criteria: In this exercise the Open and Close pushbuttons will be used to control the movement of the door. Movement will not be maintained when either switch is released, and therefore the Stop switch is neither required nor used in this exercise. However, all other available Inputs and Outputs are employed in this exercise. Pressing the Open Switch will cause the door to move upwards (open) if not already fully open. The opening operation will continue as long as the switch is held down. If the switch is released, or if limit switch LS1 releases, the door movement will halt immediately. Pressing the Close Switch will cause the door to move down (close) if not already fully closed. The closing operation will continue as long as the switch is held down. If the switch is released, or if limit switch LS2 operates, the door movement will halt immediately. If the Door is already fully opened, Pressing the Open Switch will Not energize the motor. If the Door is already fully closed, Pressing the Close Switch will Not energize the motor. If both OPEN and CLOSED are held down, Neither motor will operate. The Open Lamp will be illuminated if the door is in the Fully Open position The Shut Lamp will be illuminated if the door is in the Fully Closed position. Exercise 2 In this exercise we want you to apply your knowledge of Relay Logic to design a system which will maintain the appropriate door movement once initiated by the operator. The Opening or Closing operation of the door will continue to completion even if the operator releases the pushbutton which initiated the movement. The program will adhere to the following criteria: Door movement will halt immediately when the Stop Switch is initially pressed, and will remain halted if the switch is released Pressing the Open Switch will cause the door to Open if not already fully open. The opening operation will continue to completion even if the switch is released. Pressing the Close Switch wil cause the door to Close if not already fully shut. The closing operation will continue to completion even if the Switch is released. If the Door is already fully opened, Pressing the Open Switch will Not energize the motor If the Door is already fully closed, Pressing the Close Switch will Not energize the motor. Under no circumstance will the circuit allow both motor windings to be energized at the same time. Stop the motor. The Ajar Lamp will be illuminated if the door is NOT in either the fully closed or fully opened position while in motion or stopped The Open Lamp will be illuminated if the door is in the Fully Open position. The Shut Lamp will be illuminated if the door is in the Fully Closed position. Inputs and Outputs For each of the following OUTPUTS design a Boolean expression.
