Elevator Inspection - Tower B, Units 1-4

Building A, Floor 3, Zone 3-East Reported by Sarah Chen Jan 15, 2024 at 9:23 AM

On-Site Inspection 4/8

Tenant reports the issue started around 6:30 AM when staff arrived. Multiple complaints from Zone 3-East occupants. Priority escalated due to executive offices in affected area. Initial report came from Sarah Chen who noted the temperature was noticeably warmer than usual. Checked with building ops - no scheduled maintenance on AHU-3E. Last service was 3 months ago (routine filter change). Reviewed maintenance-log.xlsx and confirmed no anomalies in recent history. Mike Torres dispatched at 10:15 AM. He confirmed the cooling coil valve on AHU-3E is showing 100% open but not achieving target temps. Actuator making clicking noise - possible mechanical failure. See bms-alerts.pdf for full diagnostic output. Temporary workaround: Increased airflow to adjacent zones to compensate. Building Manager notified of potential parts order needed. Checking vendor availability for Belimo actuator replacement.

Instructions

Verify the reported issue and gather initial diagnostics from the BMS.

Review BMS alerts for Zone 3-East bms-alerts.pdf
Confirm temperature anomaly with sensors
Check recent maintenance history maintenance-log.xlsx

Detected temperature anomaly in Zone 3-East. Current reading is 78°F vs setpoint of 70°F. Checking BMS alerts and sensor data now.

Pulling maintenance history for AHU-3E. Last service was October 15th - routine filter replacement. No prior issues with cooling coil valve reported.

I've analyzed the BMS data for Zone 3-East. The supply air temperature has been running 8°F above setpoint since 6:45 AM. The issue appears to be related to AHU-3E's cooling coil valve, which is showing 100% open but not achieving target temps. I recommend dispatching a technician to inspect the valve actuator.

Technician dispatch confirmed. Mike Torres assigned and en route. I've also notified the occupants on Floor 3 that a technician is responding to the comfort issue.

Thanks for the analysis. I'm heading to Building A now. Will inspect the cooling coil valve and actuator on AHU-3E. ETA 30 minutes.

On site now. Initial visual inspection shows the cooling coil looks fine, but the valve actuator is making a clicking noise. Going to check the linkage and control signal next.
