_ O <br /> r x x <br /> Float Switch Assemblies <br /> Applications General <br /> Float switches are used to signal liquid level positions for alarm and All models listed are UL listed and CSA certified for use in water or sew- <br /> pump control applications.Orenco float switch assemblies can be age.Non-mercury float switches(models B,C,N,and P)are used where <br /> mounted in pump vaults,effluent screens,pump basins,and risers. components containing mercury are prohibited. <br /> Float switches are typically ordered in assemblies that include one or <br /> more switches mounted on a 1-inch PVC float stem.ABS float col- <br /> lars are used to provide secure mounting that is easily adjustable."P" <br /> On _--------- Float collar and"N"model float switches use Super Vu-Tron"electrical cords for <br /> superior chemical and water resistance. <br /> X <br /> 3 <br /> Standard Models <br /> Set point <br /> 0 <br /> B,C,G,N, P <br /> Y <br /> 00 ------------ Product Code Diagram <br /> Float tether MF S P -77FF—sl - 30 <br /> Tard length option <br /> Blank= 10 It(3 m),standard <br /> 20 =20 It(6 m) <br /> ® � 50 =50 ft(15 m) <br /> Application: <br /> FS =field set <br /> FTL = elbow-style(base-inlet filters only) <br /> PB = pump basin <br /> Float stem STEP = Stand duff(standard <br /> settings for STEP settings) <br /> STEPRO = Standard float settings for STEP with redundant off <br /> SVGOM =Standard float settings for VOOM simplex <br /> Float stem length: <br /> Blank=no float stein(floats and collars onIA <br /> 19,21,27.33,37,39,45,51,57.66=stem length,in. <br /> / 5,11 =stein length.in.(for elbow-style float brackets) <br /> ® / Float switch models(listed in order from tie top of the float stem down), <br /> B.G,G,N,P <br /> Number of float switches(when using multiples of tie same float switch model): <br /> Blank=no multiples of the same float switch model <br /> Float switch assembly <br /> When ordering float switch assemblies,remember to list float switches <br /> The"On and"off"positions describe normally open floats. from the top of the float stem down.An"MFPBN-"nomenclature indi- <br /> For normally closed floats,the functions are reversed. cates one"P"switch at the top of the stem,one"B"in the middle of <br /> the stem,and one"N"switch at the bottom of the stem;an"MF2PN-" <br /> indicates"P"switches at the top and middle of the stem,and one"N" <br /> Materials of Construction switch at the bottom of the stem. <br /> Float housing Impact-resistant,noncorrosive PVC plastic for use in liquids <br /> up to 140°F(60°C) <br /> Float cord, Flexible 2-conductor(UL,CSA)SJOOW;Super Vu-Trona' <br /> P and N models Supreme,yellow <br /> Float cord, Flexible 2-conductor(UL,CSA)SJOW;water-resistant <br /> All other models (CPE);neoprene coating <br /> Float collar ABS <br /> Orenco Systems"Inc.,814 Airway Ave.,Sutherlin,OR 97479 USA • 800-348-9843•541-459-4449•www.orenco.com NTD-MF-MF-1 <br /> Rev.2.0,r 02/16 <br /> Page 1 of 2 <br />
