Referto EIM JOB SPEC SHEET to identify the lubricant provided. Normal operationmay not require lubricant replacement.MAINTENANCEAt least once a year a check should be made of your EIM actuator.a) Disconnect all electrical power to actuator.b) Open electrical enclosure. Inspect & tighten all electrical connections.c) Visually inspect for any electrical or mechanical damage. Replace wornor damaged components.PRESSURE RELIEFDuring operation of electric actuator, thegear temperature increase in combinationwith variations of outdoor temperature willcause a small pressure build-up withinactuator gear box. EIM furnishes PressureRelief Vent Fitting Part No. 83385.Placement on Actuator can be determinedonly after field location and position ofvalve has been determined. Select thehighest 1/2 NPT vent location on actuatorgear box; remove 1/2 NPT plug andreplace with 83385. The possible locationsof vent are shown on EIM Outline Drawing.d) Check lubrication consistency and level. Fill or replace if required.EIM COMPANY, INC. 13840 PIKE ROAD MISSOURI CITY, TX 77489 (281) 499-1561 FAX (281) 499-8445
EIM E796SHORT TERM STORAGE(Stored at Job Site less than one year from shipment)1. Actuator should be stored with motor shaft in horizontalposition and electrical enclosure in either the horizontalor vertical position.2.Actuator should be stored indoors free from job sitedirt, mud, moisture and temperature changes.3.If indoor storage is not possible, the actuator must bestored off the ground above possible water or snowlevel. Remove M2CP and store with other electricaland electronic equipment in protected warehouse. IfM2CP is not removed, Space heater MUST beenergized to protect electrical controls.4.EIM supplies NPT plugs in each conduit entry. Do notremove until electrical hook-up. The customer conduitshould be routed to enter electrical enclosure at 1-1/2(1.50) NPT located at lowest point, so condensationdoes not drain into enclosure and damage parts.5.Cover units loosely with a plastic sheet. This servesas partial protection from rain.LONG TERM STORAGE(Stored more than one year from shipment)1. Store indoors or M2CP should be removed and stored in aprotected area. Follow procedures of short term storage.FAILURE TO STORE ACTUATORPROPERLY WILL VOID WARRANTY OFELECTRICAL & ELECTRONIC COMPONENTSM2CP ELECTRICAL HOOK-UP Remove PWR and TBM covers to expose terminals for customer wiring.EIM Modular Modular Control Package (M2CP) is available configured in many combinations of electrical and electronic parts.Refer to WIRING DIAGRAM and EIM JOB SPEC SHEET for components provided by EIM.

EIM E796LIMIT SWITCH SETTINGINSTRUCTIONSBEFORE MAKING LIMIT SWITCH SETTING:1. Move valve to mid-position (use handwheel).2. Phase the power (motor) voltage and make surethat open contactor moves valve Open and closecontactor moves valve Closed.DANGER: Improper power voltage phasingeliminates protection of both position limit switchand torque switches, risking valve damage.TO SET OPEN LIMIT SWITCH (LSO)1. Open valve during handwheeloperation note rotation direction ofscrewdriver (fig. 1) in LSO AdjustingShaft. After valve is fully Open, Close itthree handwheel turns to allow forcoasting when motor is actuated.2. Disengage spring loaded gear: PushDisengage Shaft in (fig. 2a) down, thenrotate 90 so shaft is captured down.This will disengage limit switch gearsfrom spring loaded drive gear.TIP: many turns may be required to setlimit switches; it may be convenient touse a reversible variable speed drill torotate the adjusting shafts instead of ascrewdriver.SET (LSC) CLOSE LIMIT SWITCH1. Close valve, using handwheel.During handwheel operation noterotation direction of screwdriverin LSC adjusting shaft. After valveis fully Closed, Open it threehandwheel turns to allow forcoast.2. Repeat steps 2 through 5 of LSOsetting instructions withscrewdriver in LSC cavity.Important: “jiggle” adjusting shafts.TO SET INTERMEDIATE SWITCH(LSA OR LSB), if included.1. Open Valve to desired position,then repeat steps 2 thru 5 of LSO.Important: “jiggle” adjusting shafts.TORQUE SEATED VALVESIf valve is a torque seated valve, andthe geared limit contacts are used forindication only, the LSC switch shouldbe set several handwheel turnsahead of torque switch contact action.This gives proper valve position Lampindication in spite of minor positionvariations which might occur due totorque seating.3. Line up LSO indicator: If switch rotorarrow does not line with round holes(within 15 ) on plate as shown in fig.3a, rotate screwdriver in same directionnoted in Step 1 until switch just rotates.If arrows line up as shown in fig. 3b,rotate screwdriver in the oppositedirection until switch just rotates.4. Re-engage the spring-loaded drivegear by rotating disengage shaft in fig.2a. Spring loaded disengage shaft willrise.5. IMPORTANT: to insure limit switchgears have re-engaged properly withspring loaded drive gear, firmly“jiggle” (rotate) all adjusting shaftswith screwdriver back and forth.Proper engagement has been madeif all shafts (LSC, LSO, LSA & LSB)will not turn with screwdriver.4EIM COMPANY, INC. 13840 PIKE ROAD MISSOURI CITY, TX 77489 (281) 499-1561 FAX (281) 499-8445

EIM E796Futronic II 8395783957-1 (600 starts per hour maximum) or 83957-2 (100 starts per hour) module controls valve by comparing two inputs(the desired position from process controller or computer and actual valve feedback position). If the two are within BAND,valve will not move. When the setpoint moves outside the BAND, valve moves in the direction to make control signal andvalve feedback position inputs balance.CalibrationAfter field wiring is complete, position limit switches have been set (Pg 4) and Pot adjustment on (Pg 5); proceed.1. Voltmeter probes ( ) in Red (FB) test point and (-) in Black (GND) test point.2. Close valve: Meter should read 1 volt DC. If it does not adjust ZERO.3. Open valve: Meter should read 5 volts DC. If it does not adjust SPAN.4. Repeat steps 2 and 3 until no re-adjustment is necessary.5. After a command signal has been connected, adjust BAND so valve moves to desired setpoint. Delay: 83957-1 has asix (6)* second fixed delay preventing actuator from instantaneously responding to another signal. This allows reversingcontactor to respond at 600 starts per hour maximum.Note:Jumper JP1 is factory set: See Job Spec Sheet for JPI position. Loss of 4-20 mA control signal will cause valve to(1) LST (last position will not move) or 2) CL valve will close. JPI jumper plug may be field changed.TIP:To measure BAND, place Voltmeter (-) Probe in Green (SIG) test point and ( ) probe in Red (FB) test point. Movevalve using Handwheel. Observe reading when valve repositions. (BAND adjustment is 1% to 7%.)* 83957-2 has a thirty (30) second delay for 100 starts per hour maximum.Note 1) Feedback Pot may be mounted on MDPI (Multi-turn valves) or mounted on gear cover (1/4 Turn valves).6EIM COMPANY, INC. 13840 PIKE ROAD MISSOURI CITY, TX 77489 (281) 499-1561 FAX (281) 499-8445
