New RTP driver output helicity phase compared to old driver
This morning Riad and I checked the output phase of the new RTP driver compared to the old one.
The output of what we have designated as the "positive" lead is out of phase with the helicity signal (figure 1).
The output of what the old driver has designated as the "positive" lead is in phase with the helicity signal (figure 2).

COMMENT ON Startup of Two Additional Central Chilled Water System Chillers and Associated Primary and Secondary Pumps and Final Commissioning
Subcontractor controls work was delayed due to a secondary pump control issue related to too rapid speed increase reaction after network communication and remote sensor communication lost events resulting in a Building 12 F-Wing relief valve lifting. Programming corrections have been made, and field deployment of the revised control programming is being coordinated. Actual uploading and fielding testing of the revised programming should occur within the next week or so once all lab requested preparatory requirements have been satisfied and system user coordination is finalized.
