Veeder-Root Sensor Application Guide 8 Stand-Alone Dispenser Pan Sensors The Stand-Alone D i spenser Pan Sensors i mmed i ately shut down AC power to the d i spenser when flu i d i s detected i n the d i spenser pan . These sensors control and shut down power to the d i spenser w i thout the need for add i t i onal relays, c i rcu i try, w i r i ng, or consoles . The separate sensor control i nterface ensures i ntr i ns i cally-safe i ntegr i ty i n a Class I D i v i s i on II hazardous area . Two models of Stand-Alone D i spenser Pan sensors are ava i lable : • Stand-Alone D i spenser Pan Sensor - l i qu i d level detect i on only (Form Number 847990-001) . • D i scr i m i nat i ng Stand-Alone D i spenser Pan Sensor - separate l i qu i d level detect i on for hydrocarbons and water (Form Number 847990-002) . Sensor Detection Capabilities - Alarm Conditions • Non-D i scr i m i nat i ng Stand-Alone D i spenser Pan Sensor D i spenser shut down when l i qu i d level reaches a nom i nal he i ght of 1 . 5- i nch i n sensor . • D i scr i m i nat i ng Stand-Alone D i spenser Pan Sensor D i spenser shut down e i ther when hydrocarbon level reaches a nom i nal he i ght of 0 . 125- i nches i n sensor, or when water reaches a nom i nal he i ght of 6 . 5- i nches i n sensor . Operating Capabilities • Operat i ng temperature range : 0 to +70°C (for freez i ng l i qu i ds), -40 to +70°C (for hydrocarbons) . • Storage temperature range : -40 to +70°C . • Controls most manufacturer ’ s d i spensers . • Connects d i rectly to d i spenser w i r i ng . • Latch i ng alarm c i rcu i try ensures d i spenser can ’ t be restarted unt i l hazardous cond i t i on has been corrected . • Cable length : 5 feet . • Sensor d i mens i ons : 11 . 6 ” h i gh, 2 . 2 ” d i ameter . • Control Interface d i mens i ons : 9 . 4 ” h i gh, 2 . 2 ” d i ameter . Compatible Fuels • Unleaded gasol i ne • Unleaded w i th up to 5% methanol, 15% ethanol, or 15% MTBE • Leaded gasol i ne • D i esel • Kerosene • Jet fuel • Av i at i on gasol i ne Installation Accessories Un i versal Sensor Mount i ng K i t, P/N 330020-012, conta i ns sensor mount i ng brackets and screws .
