bbcxo Posted January 19 Report Share Posted January 19 Heating Element: DERNORD Immersion Cartridge Heater 120V 1500W Hot Rod Heating Element Replacement 3/4 Inch Thread Pressure Sensor: Psi Pressure Transducer 4-20mA Output G1/4" Silicon Pressure Transmitter Transducer for Water Gas Oil (0-0.2MPA) using 0-30 psi Relay: Inkbird Solid State Relay 40DA DC SSR Black Heat Sink for PID Thermostat Temperature Controller Load Voltage: 24-380VAC Load Current: 40A Input Voltage: DC 3-32V Power Supply: 120-24 Temp sensor rtd pt100 Aim for the the program is to control the air pressure in an enclosed tank via a heating element. I'm assuming due to getting an error with the PID status instruction being false, the PID/Auto tune/PWM/heating element won't activate/start. Other than that, pretty lost on why the system isn't functioning. We've checked that all sensors are working.

bbcxo Posted January 19 Author Report Share Posted January 19 this was the status from the pid fixed the parameters in the pid for control/process value. Control value to 0-1000 process value: 0-30 for pressure sensor range will update if it starts working Quote Link to comment Share on other sites More sharing options...
MVP 2021 Joe Tauser Posted January 19 MVP 2021 Report Share Posted January 19 You haven't given yourself a lot of room to control here. It will work better if you set your process value to 0-3000 and use a virtual decimal point at xx.xx for pressure. Joe T.
