The AOV will be located on system B, DO(206). The control code for this AOV will be loaded in the next couple of days. Automation of this valve will reduce the operational time required to backwash V-1540 (action item from the Thermal team). When DK(109) is set to zero to backwash V-1540, the D1320 to D-1 valve will close. A new DK for system D, DK(119), is being written to enable you to bypass V-1540 without closing the valve to D-1 (if you need to bypass the filter but you don't intend to backwash it). Also, new DK's will be written in system B to enable you operate the D-1320 to D-1 valve exclusively. Please review the code after Gary loads it and sign off on the MOC in the communique book. If you have any questions, please let me know. Thanks, fun ?(amuj Run Plant Engineer CMP Plant Louisiana Operations Page 1 DO A 026674 CONFT DENT IAL.
