Display - Outlet Water Temp
Description-
Stacks’ Outlet Water Temperature sensor exceeds over-temperature threshold (72 °C)for 10 seconds.
Resolution-
Coolant is exceeding allowed temperature-rise thru IBGT stacks, prior to radiator
1. Verify Outlet Temp reading on HMI compared to IGBT temps: Monitor menu
■ Temperature 2 menu: M1A/B/C | M2A/B/C | M3A/B/C
■ Verify coolant Inlet Temp is within specification (sufficiently cooled)
2. Check coolant Temperature Sensor/Transducer TT2 in LC cabinet section: wiring
■ TB11-7 | TB11-14 | CANUX2 J7-10/5/(4-shield drain-wire)
