Controls Engineer

My alarm goes off at 6:30 AM, and I'm reviewing the overnight BMS (Building Management System) logs before arriving on-site at the data center. Immediately, I pull up the Ignition SCADA dashboard, checking critical infrastructure metrics for our hyperscale facility. Something looks slightly off with CRAC Unit 3's temperature differential in Rack Row 14 - I flag this for deeper investigation. My morning priority list includes completing a preventative maintenance sequence for our cooling infrastructure and verifying last night's firmware update on our environmental control systems. By 10 AM, I'm responding to a ticket from the network operations team regarding slight power fluctuations in our east-side server hall. I'm coordinating with our Schneider Electric vendor representative to analyze recent UPS performance data and document potential root causes. Using my engineering change management software, I draft a preliminary incident report and update our maintenance tracking system with current findings. During our scheduled maintenance window, I'm collaborating with the facility reliability team to review our latest control logic modifications for the new liquid cooling infrastructure. We're using a combination of ladder logic and structured text in our PLC programming environment to optimize thermal management efficiency. Our team walks through proposed changes to the cooling sequence algorithms, discussing potential performance improvements. The afternoon is dedicated to troubleshooting an anomalous temperature gradient we've detected in our secondary data hall. I'm using thermal imaging tools and running detailed sensor diagnostics to understand potential airflow disruptions. By cross-referencing our historical performance data with current readings, I'm developing a comprehensive analysis of potential systemic issues that might be impacting our cooling efficiency. As my shift concludes, I prepare a comprehensive handover report for the night team. I document all system observations, pending investigations, and critical metrics in our centralized tracking system. A brief video conference with the incoming shift technician ensures smooth knowledge transfer, highlighting the temperature anomalies in Rack Row 14 and the pending vendor consultation on UPS performance. I finalize my logs, ensuring complete traceability for our next system review.
