Challenges and Successes
- Issue: During functional testing, it was observed that the generator would not sync with the UPS while in static bypass mode. It was recommended that the UPS monitor a dry set of contacts located in the ATS (building alarm contact). Resolution: The electrical contractor pulled additional monitoring wiring and TMCx verified proper operation. Having the UPS sync with the associated generator in all operating conditions is a design requirement and will limit the chance of service interruption during maintenance/testing.
- As a result of TAB verification, it was identified that the chilled water closed loop system was operating at or above 75 psi. The pressure regulator has a min. set point of 25 psi and expansion tank is factory set at 12 psi. Resolution: It was recommended to reduce the system pressure to 25 psi, isolate expansion tank, and pressurize to 25 psi and re-connect to system.
