1.1 PrincipleofOperation

The designofM agnetrolfloatoperated levelswitchesis based upon the principlethata magn etic fieldwillpene - trate non-magneticm aterialssuch as316stainlesssteel. In thiscase,the floatmo vesa magn eticattraction sleeve withina non-magnetic enclosing tube and actuatesa switch m echanism . T he enclosing tube providesa pressure sealto thechamberand therefore tothe process.

1.2 OperatingCycle

As theliquid levelrisesin the cham ber(referto Figure 1 ), thefloatmo vesthem agnetic attraction sleeveup within theenclosingtube and intothe fieldofthe switch me cha - nism m agnet.A sa result,the magn etisdrawn in tightlyto theenclosing tube causing the switch to trip,“m aking” or “breaking”an electricalcircuit.A sthe liquid levelfalls,the floatdropsand mo vesthe attraction sleeveoutofthemag - neticfield,releasing theswitch ata predeterm ined “low level” (refertoFigure 2 ). The tension spring ensuresthe return ofthe switch ina snap action. 2 .0 Installation

Use pipe ofsufficientstrengthto supportthe control.If necessary,provide a stand orhangerto helpsupportits weight.All piping shouldbe straightand free of“low spots”or“pockets” so thatlow erliquidline willdrain towardsthe vesseland uppervaporline willdrain toward thecontrol.Shut-offvalvesare recom men ded forinstalla - tion between thevesseland thecontrol.Ifcontrolistobe used with a low temp eratureliquid (one w hich will“boil” inthe floatchamberifoutside heatisabsorbed),the chamberand piping shouldbe insulated. Such boiling inthe chamberw illcausefalselevelindications. DO NOT INSULA TE SWIT CH MECHA NISM HOUS ING.

Liquidina long linem aybe cooler and m ore dense than liquidinthe vesselcausinglowerlevel indication inthe controlthan actuallevelinthe vessel. C aution: Op eration of all buoyancy type level devices should be done in such a w ay as to minim ize theactionofdynamic forces on the float or displacer sensing element. Go od practice forreducing the likelihood ofdama ge tothecon - trolis toequalize pressureacross thedevice slowly.

2.5 Wiring

NOT E: Asw itch orcircuitbreakershallbe installed inclose proximity to equipm ent and within easy reach of operator.It shallbe m arked as thedisconnecting device for theequipme nt. NOT E: Fo rsupply connections in installations withambient tempera - tureup to+158°F (+70°C),use w irewitha m inimum rating of +167° F (+75° C )as required by the process conditions. Installations w ithamb ienttem peratures up to+176°F (+80°C) require wire with a m inim um rating of +185° F (+85° C )as required by the process conditions. Use a minimum of 14 AWG w ireforpow erand ground field wires. C aution: Level controls are shipped from the factory with the enclosing tube tightened and the m iddlesetscrew,on the housing base, locked to the enclosing tube. Fa ilure to loosen the set screw prior to repositioning the conduit connection m ay cause the enclosing tube to loosen, resulting in the possible leakage of the process liquid or vapor. Series3controlsare shipped w ith theconduitentryof theswitch housing placed 180° opposite to thetank con - figurations tosimplifyinstallation inmostcases. Ifthis configuration isappropriateto the installation,proceed to step 4 to begin w iring the unit. If anotherconfigurationis desired,the switch housing can be easilyrotated by first following steps1,2, and 3. 1. Loosen setscrew(s)atbaseofswitch housing. R eferto Figure 4 . 2. Switch housing m aybe rotated 360°toallow correctposi - tioning ofconduitoutlet. 3. Tighten setscrew(s)atbase ofswitch housing. 4. Unscrew and rem oveswitch housing cover.The threads havebeen lubricated to facilitate rem oval. NOT E: O n high temp eratureapplications (above +250°F [+121°C ]in float chambe r), high tem perature wire should be used between controland firstjunction box located ina coolerarea.

A sufficientam ountoflubricanthasbeen applied atthe factoryto ensure a lifetime ofservice.Furtheroilingis unnecessaryand w illonlytend to attractdustand dirt which caninterferew ith mechanism operation. C aution: Op eration of all buoyancy type level devices should be done in such a w ay as to minim ize theactionofdynamic forces on the float or displacer sensing element. Go od practice for reducing the likelihood of damag e to the control is to equalize pressure across the device very slowly.
