• The approach for updating the 3 remote flex I/O modules will be determined during the design
phase of the project. Currently we anticipate removing the clarifier flex I/O modules from the
field panels, and hardwiring the signals back to one of the I/O racks located in the blower
electrical room. We anticipate replacing the communication module on the Electrical
Distribution Panel flex I/O with an Ethernet communication module.
