-s - <br /> The Vapor Pressure Sensor <br /> The Veeder-Root ISD system requires one Vapor Pressure Sensor per GDF installed <br /> into one of the dispensers located closest to the gasoline tanks (If a row of dispensers <br /> are equal distance from the gasoline tank pad and within 10' of each other, any <br /> dispenser can be used) in accordance with the ARB Approved Installation, Operation <br /> and Maintenance Manual. The Vapor Pressure sensor shall be installed into <br /> dispensers listed in Exhibit 1 of this Executive Order. The Vapor Pressure Sensor is <br /> an intrinsically safe sensor that is wired to the TLS Console Smart Sensor Module via <br /> a conduit dedicated to TLS Console low-voltage sensors. Figure 2B-10 shows an ISD <br /> Vapor Pressure Sensor illustration. Figures 2B-13 and 2B-14 show the installation <br /> configuration. <br /> Dispenser Interface Module (DIM) <br /> Existing Dispenser Interface Modules or DIM communication cards are used to interface <br /> to the dispenser Point Of Sale (POS) or controller system to gather fuel transaction <br /> data. The ISD Operability Test Procedure provided in Exhibit 9 and in Section 4 of the <br /> Veeder-Root ISD Install, Setup and Operation Manual can be used to verify the proper <br /> selection and setup of the Dispenser Interface Module. See Figure 2B-11 for a typical <br /> Dispenser Interface Module Illustration. <br /> Tank Inventory Probe Sensor <br /> Existing Tank Inventory Probe sensors (one per gasoline storage tank) are used to <br /> measure the amount of vapor space in the Underground Storage Tanks (USTs). The <br /> ISD Operability Test Procedure can be used to verify the proper selection and setup <br /> of the Tank Inventory Probes. See Figure 213-12 for a typical Tank Inventory Probe <br /> Sensor. <br /> Shutdown Control <br /> The TLS Console must be wired per the Veeder-Root ISD Install, Setup and <br /> Operation Manual 557013-800, Rev. E of the ARB Approved Installation, Operation <br /> and Maintenance Manual such that it shall automatically prohibit the dispensing of fuel <br /> through shutdown of all the gasoline turbine pumps during a CP-201 ISD failure alarm <br /> or TLS Console ISD system power loss. <br /> TLS Console Modules <br /> The ISD Operability Test Procedure in Exhibit 9 and in section 4 of the Veeder-Root ISD <br /> Install, Setup, and Operation Manual of the ARB Approved Installation, Operation, <br /> and Maintenance Manual shall be used to verify the proper selection and setup of the <br /> TLS Console Modules. <br /> Healy Phase 11 EVR System Including Veeder-Root ISD, Exhibit 2—VR-202-D <br />
