Eliminate Unwanted Fuel
The RS-1 is an optional addition to the RAPID FLASH system and is designed to reinject the fuel used by the unit, eliminating unwanted fuel in the station sump system. The RS-1 Recovery System consists of a 15 gallon stainless steel tank, 4 level stainless steel float system, 2HP ex-plosion proof motor, reduction gear box, triplex piston pump, and a programmable logic controller (PLC). The RS-1 Recovery System has 3 modes of operation.
With the selector switch in the NORMAL position, fuel enters the re-covery tank from the flasher as it is running. The fuel will rise in the tank until it reaches the 9.4 gallon level float switch (LS1, high level). The motor / pump will start injecting fuel into the pipeline until the fuel level decreases below the lowest level float switch. If the RAPID FLASH should stop, then the RS-1 will stop because it is interlocked with the RAPID FLASH. When the RAPID FLASH resumes
operation, the RS-1 will start injecting again once the fuel level has ris-en above the LS2 float level switch. The tank will be pumped empty in approximately 5 minutes.
In the fast cycle mode, (selector switch in the FAST position) the pump will start when fuel level reaches the 3.7 gallon lowest level float switch. The tank will be pumped empty in approximately 2 minutes.
In the manual cycle mode, (selector switch in the MANUAL position) the pump unit will run as long as the fuel level is above the lowest level float switch.
The RS-1 Recovery System has alarm outputs to alert station personnel of an abnormal or malfunction condition and PLC protection to prevent tank overflow or pump / motor damage.
