___ <br />• <br />Veeder--Root Sensor Application Guide <br />t'cCEIVED <br />Lr4 <br />Stand -Alone Dispenser Pan Sensors <br />� �E.AJH <br />The Stand -Alone Dispenser Pan Sensors immediately <br />Ato the d spenserdispenser <br />witho�t the need for additieonal � <br />in tthe dispenser pan. These sensors control and shut down powe <br />relays, circuitry, wiring, or consoles. The separate sensor control interface ensures intrinsically -safe integrity in a <br />Class I Division II hazardous area. Two models of Stand -Alone Dispenser Pan sensors are available: <br />• Stand -Alone Dispenser Pan Sensor - liquid level detection only (Form Number 847990-001). <br />• Discriminating Stand -Alone Dispenser Pan Sensor - separate liquid level detection for hydrocarbons and water <br />(Form Number 847990-002). <br />Sensor Detection Capabilities - Alarm Conditions <br />• Non -Discriminating Stand -Alone Dispenser Pan Sensor <br />Dispenser shut down when liquid level reaches a nominal height of 1.5 -inch in sensor. <br />• Discriminating Stand -Alone Dispenser Pan Sensor <br />Dispenser shut down either when hydrocarbon level reaches a nominal height of 0.125 -inches in sensor, or <br />when water reaches a nominal height of 6.5 -inches in sensor. <br />Operating Capabilities <br />• Operating temperature range: 0 to +70°C (for freezing liquids), -40 to +70°G (for hydrocarbons). <br />• Storage temperature range: -40 to +70°C. <br />• Controls most manufacturer's dispensers. <br />• Connects directly to dispenser wiring. <br />'t be restarted until hazardous condition has been corrected. <br />• Latching alarm circuitry ensures dispenser can <br />• Cable length: 5 feet. <br />• Sensor dimensions: 11.6" high, 2.2" diameter. <br />• Control interface dimensions: 9.4" high, 2.2" diameter. <br />Compatible Fuels <br />• Unleaded gasoline <br />• Unleaded with up to 5% methanol, <br />15% ethanol, or 15% MTBE <br />• Leaded gasoline <br />• Diesel <br />• Kerosene <br />• Jet fuel <br />• Aviation gasoline <br />Installation Accessories <br />Universal Sensor Mounting Kit, P/N 330020-012, <br />contains sensor mounting brackets and screws. <br />Related Sales Literature <br />Visit our website at www.veeder.com for more <br />information on Veeder-Root products and <br />services. <br />Dispenser Control Interface <br />.
