The start up and ramping of a Carrier 23XRV Chiller with a Variable Frequency Drive.
The EMS had (wrongfully) cycled off the Chiller when one of the cooling towers went down (overall condenser water loop temp was ok) and the chilled water loop rose to over 60 degrees by time the chiller restarted and ramped up thus having a descent load on it with the near 100 degree outdoor temp.
I captured the soft start and ramping process.
