INSTRUCTION MANUALPRODUCTDESCRIPTIONScope Of This Manual:This manual describes and provides instructions and parts listsfor the LINC-L471, LINCL471SC, LINC-LV471 andLINC-L971 Series Electric LevelControls.Product Description:Used as a high & low levelcontrol, the L471 & L471SC canactivate alarms, provide a switchinput for control systems, or perform a variety of desired electrical switch operations actuatedby a liquid or liquid interface.Operation:As the float is moved by varying liquid height, a magnet ismoved closer to or further awayfrom a switch enclosure. As themagnet moves closer, a reedswitch in the enclosure closes.As the magnet moves furtheraway, the switch opens. The armcontaining the magnet also actsas a counterweight for the float.The float is small and will operate in liquids with a specificgravity as low as 0.4. The interface type float will operate witha specific gravity differential aslow as 0.1. The small float permits an economical installationin locations where other controlswould be cost prohibitive. Withthe optional relay mounted in anexplosion-proof case, the controlof larger electrical loads can beobtained. The manual overrideoption allows the operator tomanually move the float arm tothe test switch position.The SC Series is designed toeliminate the threaded controlconnection in mounting with theuse of a bolted ring per API recommended practice FIND. Theexternal cage allows for installation of the control at any elevation.Page 5Features: All wetted parts isolated from the environment. These levelcontrols are safe even in the event of fire. *Certified as explosion proof for Hazardous Locations: Class I,Div. 1, Groups A, B, C, D; Class II, Div. 1, Groups E, F, G; & ClassIII, Div. 1. All 316 stainless steel wetted parts provide corrosion resistance. Our sealed switch assembly prevents dust, dirt, or moisture fromaffecting the level control's operation. Classified "Factory Sealed"by CSA/NRTL/C. Cartridge switch assembly provides easy field replacement andservicing. High or low alarm, normally open or normally closed operationsimply by inverting the level control.*When a relay assembly is used, Class I, Div. 1, is limited to groups C and D.L I N C M I LT O N R OY 2 0 1 I V Y L A N D R O A D I V Y L A N D PA , 1 8 9 7 4 U S A T E L . 2 1 5 . 2 9 3 . 0 4 6 5 FA X 2 1 5 . 2 9 3 . 0 4 9 8
INSTRUCTION MANUALINSTALLATIONInstallation:Before installing the level control, inspect the unit for anydamage. The float arm mustpivot freely. Thread the levelcontrol into the desired connection. See Drawing 3 forSuggested installations. Thefloat requires a minimum clearance of 1 1/4" from the centerline of the unit for proper operation. For fail-safe operation as ahigh level alarm, the conduitconnection must be positionedto the highest possible location.For operation as a low levelalarm, the conduit connectionmust be positioned to the lowestpossible location. Wiring connections may now be made. Donot allow the wiring connectionsto pull on the switch assembly.Caution: Do not exceed switchratings.LINC-L471, LINC-L471SC:SPST, 100 VA AC with 3 AMPinrush capability, maximum 250volts.Breakdown voltage is 300volts. Electrical ratings aregiven for resistive loads. Forinductive loads, de-rate theswitch rating by 50% and do notexceed the VA ratings on theinrush current. If the appliedload is inductive, such as a relayor coil, then a protective deviceshould be used to prevent"inductive kick," which may burnthe switch contacts. The protective device recommended isdependent on the voltage used.For DC operation, a diode similar to an IN34A should be wiredin parallel with the switch. SeePage 11 wiring schematic. ForAC operation, a Varistor shouldbe wired in parallel with theswitch.For SPST Switch CartridgeWiring:White - CommonBlack - Normally OpenFor SPDT Switch CartridgeWiring:White - CommonBlack - Normally ClosedRed - Normally OpenL I N C M I LT O N R O Y 2 0 1 I V Y L A N D R O A D I V Y L A N D PA , 1 8 9 7 4 U S A T E L . 2 1 5 . 2 9 3 . 0 4 6 5 F A X 2 1 5 . 2 9 3 . 0 4 9 8Page 6
INSTRUCTION MANUALMAINMaintenance:The LINC-L471 and LINCL471SC Series electric levelcontrols have been designed tobe as maintenance free as possible. However, the componentparts are subject to normal wearand must be inspected andreplaced as necessary.Inspection and maintenance frequency depend upon the severity of service conditions.Instructions are provided in thissection for maintaining the controls as units, i.e., float and floatarm, relay and switch cartridge.All the maintenance proceduresbelow assume that the controlhas been removed from service.The switch and relay can beserviced with the controlinstalled. The power must bedisconnected before removingthe relay enclosure cover oropening the conduit fitting.Float and ArmCheck the physical clearancefor float operation. The floatmust swing freely. Solvent cleaning of the float arm chambermay be required if used in viscous or dirty liquids. If the floathas collapsed or is perforated,unscrew the float from the floatarm and replace with a newfloat. Use Loctite to secure thefloat to the float arm. To removethe float arm, drive out the pivotpin using a 1/8" punch. Wheninstalling the float arm, makecertain that the threaded offsetof the float arm is against thethick wall of the body.TENANCEconnected across the commonand normally closed contacts.Interrupt the coil power supplyseveral times while observingthe ohmmeter. No movementindicates a defective relay, coilor contacts. This procedureshould be repeated for each setof contacts in service.To remove a defective relay, simplypull the relay from the socket andreplace with a new relay.When ordering a replacementrelay, be certain to specify coilvoltage. After installing a newrelay, reconnect the switchleads.Switch:To test for switch malfunction,connect an ohmmeter acrossthe electrical leads and observethe meter as the float assemblyis mechanically operated. Nometer movement indicates aswitch failure.To replace a switch on theLINC-L471 or LINC-L471SCSeries, pull out the switch cartridge along with the grommetthrough the conduit adapter.Slide the new switch cartridgeinto the body. Route the switchwired through the grommet andseat the grommet in the conduitadapter.Relay:To test for proper relay function,disconnect the switch leads fromthe relay socket. Apply appropriate voltage to the coil terminals and observe the relay contact closure with an ohmmeterPage 7L I N C M I LT O N R OY 2 0 1 I V Y L A N D R O A D I V Y L A N D PA , 1 8 9 7 4 U S A T E L . 2 1 5 . 2 9 3 . 0 4 6 5 FA X 2 1 5 . 2 9 3 . 0 4 9 8
