A temperature sensor is wired into channel 0 of an analog input module and provides feedback to a gas control valve that is used on a heat treat furnace. The gas control valve is wired into channel 0 of an analog output module and the analog output controls the valve to adjust the temperature of the oven. Note: Use the analog I/O specs for the Micrologix 1100 trainers that are in the classroom. Refer to the Micrologix Documentation Handout on Blackboard. Temperature Sensor Specs Temperature Range: 0 to 1200 degrees Output Voltage: 0 to 10 volts Gas Control Valve Specs Operating range: 0% to 100% open Operating voltage: 0 to 10 volts Use the potentiometer to simulate the temperature sensor and the meter to simulate the opening and closing of the gas control valve. When the potentiometer is fully CW, this will represent 1200 degrees. A value of 10 on the meter represents 100% open. Just setup the Input Mov and scaling instructions for the Sensor. Move the input to N7:10 and the engineering units to N7:11 Assume the valve position is in N7:20 and setup the scaling to N7:21 and mov instruction to the gas valve output. Note: The Potentiometer will not move the Gas Valve value. A complete program would calculate the value for N7:20, We are only setting up the input and output instructions.
