r The Red Jacket Variable Speed Flow Controller (VSFC) is only to be used with CPT or VSFC pumps P200U20-2, AGP200T20-2 or P200T20-2 (Standard, Quantum or RED JACKET models). The VSFC monitors pump output line pressure to ensure a constant flow to each nozzle in the fuel line, regardless of the number of nozzles in use at any time. Depending on observed line pressure, the VSFC varies the pump's fundamental frequency and power to increase or decrease the pump's rotational speed and hence its output pressure. When multiple tanks are connected to a common product line, one tank is designated the master tank and additional tanks are designated as slaves. A VSFC unit is required for each tank in a multiple tank system, but only the master tank requires a pressure transducer. For installations that have a power conduit in the ground to the STP, and the customer does not want to bury a new wiring conduit for the VSFC-to-pressure transducer cable, a Veeder-Root Intrinsically -Safe (I.S.) barrier can be installed in the STP (NOTE: a one inch or larger conduit is required). The contractor can just pull a separate cable through the existing power conduit to the I.S. barrier in the STP (this can be done provided conduit and seal -off conductor fill requirements are met and the contractor adheres to all other aspects of the NEC or local codes). The Red Jacket VSFC can be installed stand-alone or in conjunction with a TLS -350 console. If the TLS -350 console also performs pressurized line leak detection, the VSFC independently controls the pump to maintain desired nozzle flow rate, and operates the pump for line leak testing as directed by the console using a single Pressure Transducer.
