Viewing <br />Window <br />X765 Vapor/Liquid Detector System <br />Model LS -3 Level Sensor <br />The Model LS -3 is most suitable for <br />steel, double-wall tanks. The unit is <br />positioned vertically on the bottom of the <br />tank annulus or at maximum fuel level of <br />a tank to prevent overflow. The all- <br />polysulfone level switch features a single - <br />pole, single -throw contact, actuated by <br />the float of the unit. The contact status is <br />annunciated on the X76S monitor. <br />U& lasted E86797 <br />Model LS -7 Tank. Level Sensor <br />The Model LS -7 Level Switch is designed for <br />horizontal applications where access is difficult, such as <br />a dual -wall fiberglass tank's annulus. The unit is <br />engineered to provide high -reliability point -level sensing. <br />The plastic construction is compatible with all hydro- <br />carbon liquids, providing long, trouble-free performance. <br />lasted E86797 <br />} <br />intrinsically Safe <br />Power Supply <br />Sensor Alarm <br />Modules <br />Intrinsically <br />Safe Barriers <br />Field Wiring <br />Compartment <br />Power Input <br />Terminals <br />Model LS 10 T'ank Level Sensor <br />The Model LS -10 consists of a reservoir mounted on <br />an Owens -Coming fiberglass tank ("P" style) annulus <br />riser and an integral level sensor. The reservoir and the <br />annulus are filled with water to at, <br />least one foot above the tank. <br />Any loss of water due to a •� <br />leak will be sensed t <br />and alarmed on the., , <br />appropriate window of the <br />Model X76S. vww� <br />U& Listed E86797J-1ZI;`41 1 *1 <br />S <br />Model HV Uapor Sensor <br />The Model HV Vapor Sensor is designed for industrial <br />and commercial applications with exposure to <br />hydrocarbons over long periods of time. The solid -state - <br />type sensor provides long trouble-free performance and <br />will not deteriorate due to continuous exposure to <br />residual vapor, inherently present in double-wall tanks, <br />dry wells and sumps. <br />CListed E100826 <br />PA -ah -.2m <br />0 <br />Typical Installation <br />Wiring Information <br />r ----------------I <br />Intrinsically Safe Wiring Only <br />A I <br />( 3B <br />I A I <br />2B <br />I <br />2A- <br />_4k_ <br />I IB I <br />I to I <br />FCI FC2 FC3 FC4 <br />L — — — — Sensor #1 #3 _ #4— — _ <br />Intrinsically Safe Field Contact Input <br />Mechanical Dimensions <br />Liquid <br />Sensor <br />Vapor <br />Sensor <br />Vapor Sensor <br />Model HV <br />12.00" (30.48 cm) <br />Manhole Cover Existing <br />r- Grade <br />Concrete <br />2" or 4" Dia. <br />Threaded PVC Cap <br />.75" (1.91 cm) Rigid Conduit <br />Red <br />White <br />Dry Well Black <br />Vapor Sensor <br />Model HV <br />Bentonite <br />No. 3 Mesh Sand <br />ImBottom Cap <br />AUX4 AUX3 AUX2 AUXI <br />Alarm Auxiliary Output (Safe Area) <br />.75 in. <br />(19.05 mm) <br />------------- <br />9.50 in. <br />(241.30 mm) <br />4.20 in. <br />X6.68 nun) <br />OT <br />ACK <br />V+ <br />V_ <br />Al <br />Spare <br />NOS <br />C AUX4 <br />NCJ <br />N07 <br />C AUX3 <br />NC—) <br />N07 <br />C AUX2 <br />NCJ <br />N07 <br />C AUXI <br />NC -J <br />H <br />N <br />G <br />�H N G, <br />115 VAC <br />Input Power <br />9.00' .22 in.
