Page 9: Function
Function „Divert Flow“ position The „Divert Flow“ position is the start position of the valve after assembling in which the divert valve routes the product back to the balance tank during periods of sub-legal pasteurization temperatures. The valve position is detected by a sensors installed in the control module. - Page 10 “Leak Detect Flush Time Delay” Leak Detect Valve position Divert Valve The Flow Diversion Device will move into the “Leak Detect” position once the legal pasteurization tempera- ture is achieved. The time of the clearance is controlled by a Flow Diversion Device Controller which is a sepa- rate device.
