E3 Tile Chaos to Clean Startup Screens: Organizing CO₂ Racks, Layouts, and a Firmware ‘Oops’

Brett Wetzel and Kevin Compass kick off this rowdy Advanced Refrigeration Podcast episode with travel talk and a quick rant about getting an E3 to communicate after an IP change, then jump into turning a messy CO₂ rack tile setup into something actually usable. They walk through creating and reorganizing tile groups (receiver, gas cooler, suction groups, oil separator, cases, etc.), explain why breaking menus down makes troubleshooting faster, and show how to build custom layout/startup screens with the key points techs actually need (pressures, temps, valve %, superheat). Along the way they discover icon management, debate the “misc/other” junk-drawer tabs, fumble through the lack of search, and even start a firmware/display update while joking about what might slam shut if it goes sideways. They finish with a quick Modbus address tip and plans for future E3 training videos.

Sensors and Pressure Transducers: Ranges, Power Requirements, and Troubleshooting TipsThe hosts discuss travel fatigue, long commutes, and airport TSA delays that led to canceling a flight and driving instead, then shift to field work issues during store startups and CO2 conversions, including controller communication problems caused by cabling, IT security port shutdowns from new MAC addresses, and router performance differences. The main technical focus is identifying and troubleshooting pressure transducers and temperature sensors: common signal ranges (1–6V, 0.5–4.5V, 0–5V, 0–10V, and 4–20 mA), matching transducer power requirements (5V, 12V, 24V/24–36V), and selecting correct pressure ranges for applications up to CO2 gas coolers. They cover sensor types (PT1000, 10K2 vs 10K3, 2.2K, 3K, 86.3K), wiring/offset issues with PT1000 over distance, and using linear interpolation apps to convert measured voltage to expected pressure or controller readings. They briefly mention megger use and plan to discuss CO2 leak detection and drain-related concerns next week.
