CX OPERATION
CX---------
CX
CX DO(206) opens when the following conditions are TRUE:
CX
CX - the quench system enters the RUN step, STEP(206)
CX - DC(2763) is TRUE, indicating the V-1540 filter bypass
CX valve, AO(305) is not being bypassed and backwashed.
CX - or DK(70) is TRUE
CX - and one of the P-1320 pumps are running.
CX
CX DC(2763) = DC(2763) will become false, closing the AOV, when the
CX operator request to backwash V-1540 filter by setting
CX DK(109) false on system (D).
CX
CX Once the filter is backwashed and DK(109) set to
CX TRUE, DO(206) will become enabled and open.

CX There are 2 DK'S for V-1540. 0K(109) being set false, indicates
CX that the filter is to be bypassed and backwashed. DK(119) being
CX set false indicates that the filter is just supposed to be bypassed.

In the next week or so, Hebert valve will come in and install an actuator on the 2" manual valve from D-1320 to D-1 (at D-1320) to convert it to an AOV. 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,
