- 8 - Veeder-Root ISD System Specifications TLS Console & ISD Software Version Number The ISD audible alarm shall be installed at a location that is most likely to be occupied by the station attendant during normal station operation (e.g. cash register) to hear the alarm. The TLS console shall be installed in a location that allows the RS232 port to be easily accessible, and if applicable, per district requirements, for use at anytime. A vacant RS232 serial port shall always be available to electronically download reports. The presence of ISD and the ISD software version number can be verified on the TLS Console LCD screen by using the <STEP> key or by using the TLS Console <PRINT> key to print and review the latest ISD Daily Report. See Figures 213-4 and 213-5 for TLS and ISD verification instructions. The TLS Console must have a printer as well as an RS232 interface port. If the TLS is equipped with security features which prohibit access to the TLS, instructions to override these security features shall be maintained on site in accordance with air district requirements and shall be available to the air district upon request. Operability Test Procedure The Veeder-Root ISD operability test procedure provided in Exhibit 10 and Exhibit 17, and in section 12 of the ARB Approved Installation, Operation and Maintenance Manual(IOM), shall be used at GDF sites to determine the operability of the Veeder-Root ISD system to comply with applicable performance standards and performance specification in CP-201. Testing the ISD equipment in accordance with this procedure will verify the proper selection, setup and operation of the TLS Console sensors and interface modules. The Vapor Flow Meter The Veeder-Root ISD system requires one Vapor Flow Meter per dispenser installed in accordance with Section 15 of ARB Approved IOM(Veeder-Root ISD Balance Vapor Flow Meter Manual Installation Guide (577013-916, Rev. B)) for the Veeder-Root ISD System. The Vapor Flow Meter is an intrinsically safe sensor that is wired to the TLS Console Smart Sensor Module via a conduit dedicated to TLS Console low-voltage sensors. Figure 26-6 shows the ISD Vapor Flow Meter. Figures 213-10 and 26-11 show the installation configuration. The Vapor Pressure Sensor The Veeder-Root ISD system requires one Vapor Pressure Sensor per GDF installed into one of the dispensers located closest to the tanks (If a row of dispensers are equal distance from the tank pad and within 10' of each other, any dispenser can be used) in accordance with Section 13 of the ARB Approved IOM Manual. For vapor vent stack installation, determine which vapor vent stack line is closest to the tank being monitored. Select this line for the addition of the pressure sensor. The connection must be BELOW the Veeder-Root Carbon Canister if equipped in accordance with Section 13 of the ARB Approved IOM Manual. Caution: Installation of the pressure sensor on the vapor vent stack is only allowed at facilities equipped with a Veeder-Root Vapor Polisher or Franklin Fueling/Healy Clean Air Separator. The Vapor Pressure Sensor is an intrinsically safe sensor that is wired to the TLS Console Smart Sensor VST Phase 11 EVR System Including Veeder-Root ISD, Exhibit 2 -VR-204-H
