Challenges and Successes

Issues: The boiler staging sequence was found to be problematic. One is designated as the master and if shut off, the remaining 2 boilers go in to standby. Loss of redundancy in event of boiler 1 failure is an issue. If any failure occurs in lead boiler, the boiler will continue to control the other two, however, if the lead boiler is powered off, the other two boilers would not operate since they are getting their water temperature set point form the Lead. If lead boiler needs to be powered off for whatever reason, the other two boilers would need to be placed out of the cascade mode and operate on manual set point
Resolution: The boilers were re-wired for proper cascading and BMS monitoring and control.
Issues: During testing, we found a cross connect in the auto transfer wiring causing a direct short between utility power and generator power, immediately opening winding safeties on generators
Resolution: The electrical contractor rewired ATS to prevent further issues
