GENERAL DESCRIPTIONThe electric capacity control actuator can befurnished in place of the standard manualmicrometer adjustment. The actuator adjustspump capacity from an electronic signal ormanually by means of an override handwheel.Local capacity indication is read directly from anindicating scale on the actuator, or remotely byuse of the electronic retransmission signal (4-20MADC) feature. Control is achieved through theuse of down sized state of the art electronics andsynchronous motor technology in a singlecompact enclosure.

Synchronous Motor

The use of this type of motor permits rapidresponse and precision positioning in a smallpackage. Since this kind of motor is magneticallydetented, overshoot is eliminated, a probleminherent in shaded pole or gear motors.

Electronics

The operation of the electric capacity controlactuator is controlled by two electronic circuitcards. The top one serving as the input and logicsection and the bottom serving as the powersupply and motor driven section. These circuitsaccept an input signal from a process instrumentand commands the synchronous motor to driveto a corresponding position. Closed looppositioning is accomplished through use of afeedback slide wire.

Description of Electronic Circuitry

Input Buffer/Motor Logic 170071. Input Buffer Amplifier: The input voltage signal

is converted from 1-5 VDC to a 0-10 VDC signalusing a high impedance amplifier, U4A. Thisvoltage is applied to the ratio control which isused to scale the signal to the appropriate value.The resultant voltage is the positive input to theerror amplifier, U4B, which compares it to theactual capacity control position as representedby the negative feedback potentiometer whichis gear driven by the actuator motor.

2. Error Amplifier and Motor Logic: The errordeveloped at U4B is applied to twocomparators, U5A & U5D, which have slightlydifferent set points. Any error in excess of thesepre-selected values will cause the motor logic,U6A or U6B, to respond with either an up (+) ordown (-) signal. The signal then enters the motordrive Section which provides currentamplification through transistors Q3 or Q4.

3. Feedback Buffer: The previously mentionedfeedback potentiometer picks off a voltage from+5 VDC to -1.2 VDC, depending upon itsposition as the motor rotates. This voltage isapplied to the feedback buffer amplifier forcomparison with the input signal. At the sametime, this signal is applied to the electroniclimiting circuitry U5B and U5C. Thesecomparators are set (via high and lowpotentiometer) to limit actuator travel in theevent of an overdriven or underdriven input.

Power Supply/Driver Card 17006Power Supply

The transformer output is rectified by a full wavebridge, filtered and routed to a pre-regulator stage.This darlington pair is controlled by zener CR3referenced to the output of the primary regulator,U1. The 5 volt reference U2 is tied to U1 through adropping diode CR2 and held 1.2 VDC above thesupply return in order to permit live zero voltagefeedback potentiometer operation without offset.

Motor Driven

The current amplified up and down signal entersthe motor driver selection at pin two of the opticallyisolated triac drivers U7 and U8. these optoisolators

INSTALLATION INSTRUCTIONSThe electric capacity control has been factory testedand calibrated on the pump prior to shipment. Nofurther field adjustments or calibrations to the factorysettings should be necessary prior to placing unitinto service.

Note: To maintain correct alignment andsupport, it is recommended that the pump/actuator combination remain bolted to its factorysupplied base plate for Series 200, 977, 997,1000 and 2000 pumps.

CAUTION: Do not adjust capacity handwheelbeyond the limits of the indicating scale ordamage to the pump and actuator may result.

Electrical Connections1. Unscrew end cover to expose with connection

points. Refer to drawing on page 12 for hookupdiagram.

2. Power and signal wires SHOULD BE RUNSEPARATELY. Use shielded cable for signal line.The electric capacity control requires a powersource of 120 VAC 50/60 hz single phase. Thebranch circuit should be protected by a fuse orcircuit breaker and contain a disconnect switch.The circuit boards are protected by a selfcontained fuse.

3. The black wire should be the phase side of theline and connect to terminal “L”; the neutral orwhite wire to terminal “N”. Equipment groundingis effected by connecting a green wire to one ofthe screws in the housing, the other end of thiswire is returned to protective ground at thesource of supply.

Note: Appropriate conduit hubs must be used,and all covers must be in place and tight toprevent liquid entry and maintain NEMA integrity.

Signal Inputs1. The electric capacity control accepts a voltage

signal of 1-5 VDC. If the controlling signal is acurrent signal, the 249 ohm resistor (R133) willtransform it into the voltage required. It may beleft in place when a voltage signal is used, but

the transmitter must be low impedance output.Better practice is to remove the resistorcompletely.

2. The 249 ohm resistor is the correct value for 4-20 MADC input. This resistor (R133) is locatedadjacent to J1 and in back of TB1 on the inputbuffer/motor logic card (17007). If a highimpedance voltage source is used, the resistorcan be removed by carefully clipping the leadat the resistor body (R133).

3. Connections have been provided that allows theactuator to be disabled. A N.O. dry contactconnected to J1 (when closed) will disable themotor drive circuit while allowing the remainingcircuitry to be fully activated. This permits theactuator to be set and then disabled, while stilltransmitting a positioner signal (4-20 MADC). Italso permits manual override while the unit ispowered up. Connections to J1 are made viaan MTA two pin connector on .100” Centers.

START UP INSTRUCTIONS1. Apply power to the actuator and inject a 4 MADC

signal at B1 to bring the actuator to zero percentcapacity. Place a mark on the slotted coupling(3409 drawing 17017, 17018). Inject a 20 MADCsignal and count the number of turns. For Series1000, 977, 997 and 200, there should be tenturns for 100% output. For Series 2000, thereshould be twenty turns for 100% output. Anydifferences can be corrected by adjusting theratio potentiometer R130 on input buffer board17007.

The electronic limiting feature built into theactuator circuitry permits only a few degrees ofpositioner rotation past 100%, likewise, a fewdegrees below zero percent. This is to preventmechanical jamming of the actuator. Whenadjusting the actuator by means of the overridehandrail, it is important to maintain indicatortravel within the limits of the indicating scale, ordamage to the actuator can occur. The manualoverride should be used in conjunction with theactuator disable feature or with power removedfrom the actuator. See section 3, under “SIGNALINPUTS” for the actuator disable feature.

2. The ratio control potentiometer is used to adjustthe full scale output of the pump for a full scaleinput signal. If it is desirable to have less than100% pump output for a 100% input signal, theratio control pot should be turned in a

page 4

counterclockwise direction from its normallymidscale position. If 100% output is required forless than 100% input signal, the pot should beadjusted in a clockwise direction. Smalladjustments are in order because of the highgain system employed. (Any change in the ratiocontrol from the factory setting will require re-calibration of the pump).

3. Remote indication or closed loop operation canbe accomplished using the 4-20 MADCretransmission feature located at TB3. “COM”is the low or negative side and “OT” is the highor positive side. Apply 4 MADC to the input,(allow actuator to position itself) and adjust thegain pot to 20 MADC output. Since the offsetand gain pots interact with each other, severaladjustments from 4 to 20 MADC may be requiredto complete the calibration. The input and outputsignals are isolated from phase and ground butnot from each other. The maximum load thatcan be connected across TB3 is 500 ohms.

CALIBRATION OF THE CIRCUIT BOARD -Series 1000

Note: The P.C. Cards are tested, calibrated andmatched to each actuator motor and pump atthe factory, and are ready to be placed intoservice as received. The following instructionsare included as an aid in troubleshooting in theunlikely event of a malfunction.

Equipment Required1. 120 VAC supply.

2. Adjustable DC voltage source capable ofsimulating 1-5 VDC or a current source capableof 25 MADC.

3. A digital voltmeter reading .01 volts minimum.

4. Miscellaneous jumpers.

Extent of Calibration: This procedure covers thesetting of the zero and the span potentiometer,checking the high and low limit potentiometer, andsetting the ratio control. This procedure assumesthat the input signal range is 1 to 5 VDC, or 4-20MADC.

Preliminary: Connect (but do not turn on) the ACpower to terminal L&N (TB2) on power supply board17006. Safety ground can be connected at thehousing or under the screw head of a standoff.Connect adjustable DC voltage supply to terminalC-and V1 + (TB1) on input board 17007.

Input Amplifier1. Apply line power to board. Read voltage from

TP2 & to C-.

2. Connect a jumper (across the zero pot) fromR102 (inside leg) to C. Apply 5 VDC to input andadjust span pot for 12.5 VDC at TP2.

3. Remove jumper across zero pot. Apply 1 volt toinput and adjust zero pot for 0.0 V at TP2.

4. Apply 5 VDC to input and adjust span pot for 10VDC. All voltages are ±0.1 VDC.

5. Repeat steps 3 and 4 as required.

Motor Limits: The high and low potentiometers onthe input board are factory set for each actuator/pump combination and require no furtheradjustment.

Checking Motor Limits1. Input 0.98 VDC. Read voltage from test point h

(+) to common.

2. Input 0.94 VDC. Observe that voltage goes onhigh.

3. Input 2 VDC then 0.98 VDC. Observe thatvoltage goes on high.

4. Input 5.08 VDC. Read voltage from test point g(+) to common. Observe that voltage is high.

5. Input 5.13 VDC. Observe that voltage goes low.

6. Input 4 VDC then 5.08 VDC. Observe thatvoltage goes high. This procedure is for checkingproper operation of motor limits only.

Note: The above voltages are typical and willvary with pump/actuator combination.

Setting Ratio Control1. Input desired voltage for full scale operation.

2. Adjust ratio potentiometer for desired pumpoutput, turn clockwise to increase output,counterclockwise to decrease output.

Returning to Service1. Remove power and disconnect all test

equipment and jumpers.

2. Reconnect power and input/output signal cablesif other sources were used for calibration check.

3. Replace all covers securely to maintain NEMAintegrity.

DISASSEMBLYRemoval of P.C. Cards1. Remove and lock out power and signal to

actuator and pump.

2. If possible set pump to 0% capacity usingmanual override hand wheel and capacity scale.

3. Remove cover from actuator.

4. Disconnect incoming power and signal lines andoutgoing signal line if used.

5. Remove feedback potentiometer cable from P2on card 17007.

6. Remove motor control cable from P1 on bottomcard 17006.

7. Remove the three screws (3417) retaining themotor logic card to standoffs (3548). Drawings17018 & 17017 (depending on Series of pump).

8. Remove the three standoffs (3548) retainingpower supply to standoffs (3547).

9. Unplug phase shift network leads from the wireson the underside of the power supply card.

10. Remove P.C. Cards as a pair and place them ina safe location. Care must be taken to preventbreakage of interconnect cables.

Removal of Synchronous Motor1. Remove the three standoffs (3547) attached to

the motor plate (3402). It is recommended toidentify these standoffs soles on the motor platefor reassembly later on. These standoffs are twoinches long and should not be confused withstandoffs (3458) which are one and one halfinches long. Clip off and discard any tie wrapsretaining interconnect wiring to these standoffs(3547).

2. Remove the Zerust anticorrosion pad thenremove the four flathead screws (3416) retainingthe motor plate (3407) to the four motor standoffs(3415). Carefully remove the motor plateassembly and inspect all components forbreakage or wear. Replace worn or brokenpotentiometer and drive gears. It may benecessary to loosen (not remove) the potbracket screws on the lower side of the motorplate (3407) to allow removal of motor plateassembly from actuator housing.

3. Remove the four motor standoffs (3415)retaining the motor in place. The motor is placedinside the actuator housing with the connector

at the three o’clock position relative to the conduitentry holes. During reassembly the motor mustbe installed in this same position.

4. Carefully remove the motor and inspect for wearor breakage of the drive components. The motorshaft must turn freely, but will exhibit a detentedor slightly “rough feeling” when turned by hand.The motor must be replaced if the shaft is hardto turn or “frozen”. Check the motor coupling(3431) for breakage or wear. If the coupling isusable be sure the set screws (3432) are tight,securing the coupling to the motor shaft.

The motor shaft is flatted and one of the two setscrews must engage this flat. It is also advisableto use “retaining” grade Loctite to aid in securingthe motor coupling (3431) to the motor shaft. Toavoid damage to the motor apply Loctite to theI.D. of the coupling (3431) at the large end beforesliding it over the motor shaft. See drawing17124-1 for coupling replacement procedure.

5. Check the motor gear (3437) for wear orbreakage. If the gear must be replaced be sureit is oriented with the teeth facing outward (awayfrom the motor). Care should be taken to assurethe spacer under the motor gear is in placebefore installing the new gear. Reassemble theoverride coupling (3409) to the motor shaftabove the motor gear (3437). If any drivecomponents appear worn (beyond use) orbroken, contact NIKKISO Pumps America, inc.or your local factory representative forreplacement parts. See “replacement partnumbers”.

Removal of Actuator Housing from PumpSeries 1000Most serviceable parts are contained within theactuator housing, and are accessible withoutremoving the housing from the pump. Theseinstructions are provided for your convenience inthe unlikely event the housing must be removed.

1. Remove support stud (3425). In mostapplications this will be a length of “all thread”with accompanying lock washers and nuts.

2. Remove the four screws (3418) retaining thecapacity plate (3414) to the actuator housing(3402). This plate has been factory sealed andmay require some gentle persuasion to break itfree. Set the plate in a safe area.

3. Reach inside the housing, using a flat object(three quarter inch wide machinist scale) and

page 6

turn the actuator (3404) until the slotted end ofthe indicator pin (3413) is accessible throughthe capacity plate opening. This pin has beenfactory installed using low shear grade Loctite,use the correct size screwdriver and removethe indicator pin and set it in a safe place.

4. Loosen, but do not remove, the four clamp ringscrews (3442). This releases clamp ringpressure, permitting the actuators to beunscrewed from the mounting adapter (3401).

5. Turning counterclockwise, unscrew the actuatorhousing from the mounting adapter (3401).COUNT THE NUMBER OF TURNS AS YOUGO. This information will be necessary forreassembly of the actuator to the pump.

6. Inspect the indicator ring (3412) and pin (3413)for wear or damage. Replace as necessary,

7. Inspect the actuator coupling (3404) for wear ordamage. The actuator must turn freely insidethe housing. End movement between housingand actuator is a normal condition though radialmovement should be negligible to nonexistent.If excess radial movement is detected, housing(3402) and/or actuator (3404) should bereplaced.

8. To replace a worn or damaged actuator (3404),set the housing (3402) on end and reach insidewith a pair of snap ring pliers and remove snapring (3433). This will allow the actuator to beremoved from the housing. When replacing theactuator (3404), apply a thin film of moly greaseto its minor diameter before inserting it into thehousing, and retain it in place using a new snapring (3433). Electric capacity controldisassembly instructions stop at this point.Further disassembly of the pump is coveredunder separate print. Contact NIKKISO PumpsAmerica, Inc. for this information.

Removal of Actuator Housing from PumpSeries 2000Most serviceable parts are contained within theactuator housing, and are accessible withoutremoving the housing from the pump. Theseinstructions are provided for your convenience inthe unlikely event the housing must be removed.

1. Remove the support stud (3425). In mostapplications this will be a length of “all thread”with accompanying lockwashers and nuts.

2. Remove the four screws (3418) retaining thecapacity plate (3414) to the actuator housing

(3402). This plate has been factory sealed andmay require some gentle persuasion to break itfree. Set the plate in a safe area.

3. Loosen, but do not remove, the two adaptorhousing set screws (3429) on adaptor housing(3428). Grasp the actuator housing (3402) firmlyand in a clockwise direction, turn the adapterhousing (3428) six to eight turns to completelyseparate actuator housing (3402) from adaptorhousing (3428).

4. Inspect capacity indicator and indicator pin forwear or damage. Replace as necessary.

5. To remove the capacity indicator and pin, turnthe indicator until the pin is in the vertical position.Support the threaded adjuster (4633) andcarefully drive the pin out using an appropriatesized drift (punch). To install a new indicator andpin, support the adjuster and align one of theholes in the indicator over the hole in the adjustershaft with the raised section if the indicator facingaway from the pump housing. Place the pinthrough the hole in the indicator and hold it inplace over the hole in the adjuster (4633).

Carefully drive the pin through the hole in theadjuster until there is an equal amount ofexposed pin on either side of the adjuster shaft.Care should be taken not to deform the indicatorduring installation or binding may occur.

6. Inspect the actuator coupling (3404) for wearand damage. Actuator must turn freely insidethe housing. End movement between thehousing and the actuator is a normal conditionthough radial movement should be negligible tononexistent. If excess movement is detected,housing (3402) and actuator (3404) should bereplaced.

7. To replace a worn or damaged actuator (3404)set the housing (3402) on end and reach insidewith a pair of snap ring pliers and remove snapring (3433).

actuator (3404) with the raised end toward thehousing (3402).

2. Align the housing (3402) with the pump adaptor(3401). Turning clockwise, start and then screwthe housing onto the adaptor using the samenumber of turns required for removal bringingthe flatted surface by the conduit entry holesparallel to the base plate (plate the pump ismounted to).

3. Tighten the four clamp ring screws (3442).Check for any radial movement of the housing.If movement is detected, loosen the clampscrew and turn the housing (3402) one turnclockwise and retighten the four clamp ringscrews.

4. Turn actuator (3404) to align a slot with thethreaded hole in the control spool assembly(3439). Slide the indicating ring (3412) in place,and insert the indicator pin (3413) through oneof the two holes in the ring, down through theslot, and into the threaded hole of the controlspool (3439). Turning clockwise, screw theindicator pin (3413) through the control spooland down through the hole in the opposite sideof the indicating ring (3412). Ends of the pin maynot protrude past the raised section of theindicator ring.

5. Remove old sealant from the capacity plate(3414) and its mating surface on the housing.Apply a film of clear RTV (silicone) to the matingsurface on the housing and secure the capacityplate in place over the RTV using the four screws(3418).

6. Install the stud (3425) with its hardware into thebottom side of the housing (3402). It may benecessary to loosen the clamp ring screws(3442) to allow slight housing repositioning wheninstalling this stud. Retighten the clamp ringscrews first then secure the stud (3425). Thisstud is intended for support only. Care shouldbe taken when tightening the jam nuts to preventthe introduction of lateral forces that might causemisalignment between the pump and theactuator housing.

Installing Actuator Housing on Pump Series20001. Apply a thin film of moly grease to the threaded

end of adaptor (3428). Align housing (3402),actuator (3404), capacity indicator (3412) andhousing adaptor (3428). In a counterclockwisedirection, screw the housing adaptor (3402) untilintimate contact is made between these twoparts. Bring the flat surface of the conduit entryholes in the housing (3402) parallel to the baseplate (plate the pump is mounted on). Hold theactuator housing in this position and install thestud (3425) with its hardware into the bottomside of the housing (3402). Tighten the two setscrews (3429) first, then secure the stud. It isimportant to seat the two set screws (3429) inthe groove (undercut) portion of the adjusterhousing (3436). Stud (3425) is intended forsupport only, and care should be taken whentightening the jam nuts to prevent the introductionof lateral forces that might cause misalignmentbetween the pump and the housing (3402).

2. Remove old sealant from the capacity plate(3414) and its mating surface on the housing.Apply a film of clear RTV (silicone) to the matingsurface on the housing and secure the capacityplate in place over the RTV using the four screws(3418).

Installation of the Synchronous MotorThe motor assembly must be complete with coupling(3431), spacer, gear (3437), and override coupling(3409). Connector with red, black and white wiresis also considered part of the motor assembly andmust be in place.

1. Insert the motor into the housing engaging thecoupling (3431) with actuator (3404). The motormust sit squarely in its mount with no movementother than rotational.

2. Orient the motor so the connector is at the threeo’clock position relative to the conduit entry hole(conduit holes at the twelve o’clock position).Secure the motor in place using the fourstandoffs (3415). If new standoffs are beingused, it is recommended to apply a thin film ofgrease to the male threads before installation.

3. The motor plate should be a built up assemblyof (3407), phase shift network consisting of2.5UF capacitor and a 500 ohm resistor, and afeedback pot assembly. Locate this motor plateassembly over the four motor standoffs (3415)

page 8

with the feedback pot at the bottom (sideopposite conduit entry holes). The two feedbackpot bracket screws (6-32 x 1/2) should be looseat this time to allow full disengagement of thetwo gears (3437) and (3438).

4. Install the three standoffs (3547) in the holesidentified during disassembly.

5. This step is for Series 1000 pumps only. Turnthe motor shaft counterclockwise (via slot onthe override coupling 3409) until it reaches itsmechanical stop. Then turn the shaft 1/4 turnclockwise. This is 0% capacity of the pump.

6. This step is for Series 2000 pumps only. Turnthe motor shaft clockwise (via slot on overridecoupling 3409) until it reaches mechanical stop.Place a mark on the coupling at the twelveo’clock position. Now, turn the couplingcounterclockwise one and one half turns. Thisis the 100% capacity. Now turn the couplingcounterclockwise twenty turns. This is 0%capacity.

7. The pump and the actuator are now ready to besynchronized.

4. Connect test cable plug (NIKKISO Hydroflo® partnumber 17120-1) to P1 on power supply/drivercard 17006.

5. Place these two cards on an insulated surfacesuch as cardboard, plastic, etc. Do not allowthe two cards to touch each other or any metallicsurface.

6. Connect 115 VAC light bulbs with pig tails (anywattage) to the test cable wires. The white wirefrom P1 is common or neutral to both lights, theblack is hot to one light, and the red is hot to theother light. See test cable schematic drawing17121-1. Do not connect the phase shift networkwires at this time.

7. Apply a 4 MADC or 1 VDC input signal to TB1.Make sure that negative, common or low isconnected to “C” on TB1.

8. Apply 115 VAC power to the card set. One ofthe two light should come on. If none of the lightscome on, check the following:

A. Power is present at TB1 of 7006.

B. Power supply fuse open or broken lead.

C. That J1 is NOT jumpered.

D. Light bulbs are operational.

E. Feedback pot is already at 0% position. (Thiscan be checked by rotating the pot gear oneturn clockwise or counterclockwise).

F. Interconnect wiring for breaks ormisconnections.

9. Turn the feedback pot gear clockwise until bothlights go out.

10. Remove 115 VAC power first, then remove theinput signal.

11. Carefully engage the feedback pot gear to themotor gear and tighten both 6-32 x 1/2” screws.On Series 2000 pumps, care must be taken tomaintain equal distance from standoffs to potgear. (Gear centered between both standoffs.)Actuator and pump are now synchronized.Remove power, feedback pot and test cableconnections from both cards.

12. Replace the Zerust vapor capsule. If a newcapsule is being used, do not forget to date it.This capsule should be replaced on a yearlybasis.

13. Position the power supply card over the threestandoffs (3547) oriented with TB2 atapproximately the five o’clock position. Be sureall three black fiber washers are in place on theunderside of the power supply card and overthe mounting holes securing it in place with thethree shorter standoffs (3548).

14. Connect the motor leads red, black and whiteto P1 on the bottom card, feedback pot leadsgray, brown and yellow to P2 on the top card,and the phase shift network leads to the redwires on the underside of the bottom card.These wires should be tied back and clear of allmoving parts, override shaft area and the conduitentry holes.

15. Reconnect 115 VAC power and signal lines toP.C. Cards. Apply a 4 MADC signal and then

page 9

apply 115 VAC power. Place a mark on theoverride coupling (3409). Inject a 20 MADCsignal and count the turns from 4 MADC to 20MADC. There should be ten turns for Series 900,1000 and Hydromyte, and twenty turns for Series2000. Any differences can be adjusted out usingthe ratio pot R130. Before making the finaladjustment to the ratio pot, high limit must bechecked. Apply 20 MADC and very carefullyadjust the ratio pot clockwise (extremely smalladjustments are in order) and note the amountof rotation past one hundred percent. Therecommended allowable is one-eight turn. If thecoupling rotates more tan one-eight (1/8) turnpast one hundred percent, adjust the ratio potcounterclockwise (decreasing capacity) enoughto bring the coupling (3409) one turncounterclockwise from one hundred percent.Adjust the high limit pot (R128) counterclockwiseone turn. Readjust the ratio pot (R130) clockwiseand check maximum rotation past one hundredpercent. Repeat this procedure using smallincremental adjustments until the actuator fallswithin stated operating parameters. After initialadjustment, increments of one half turn or lessshould be used on “HI” pot (R128). Adjust theratio pot (R130) for the one hundred percentposition. Inject a 4 MADC signal to bring theactuator to zero percent capacity. Remove theinput signal altogether and note the amount ofrotation below zero. There should be no morethan one-eight (1/8) turn. If more than one-eight(1/8) turn or jamming occurs, inject 6 MADC andthen adjust the low pot (R129) clockwiseapproximately one half turn. Inject 4 MADC tobring the actuator to zero capacity and thenremove the signal altogether and again observecounterclockwise rotation below zero. Repeatthis procedure using small incrementaladjustments until actuator falls within statedoperating parameters. This concludes theresynchronization procedure.

RETURNING TO SERVICE1. Reconnect wiring to actuator and pump motor

making sure all conduit and hubs are liquid tight.Do not apply power at this time.

2. Connect suction and discharge piping.

3. Adjust oil level as required and replace oil cover.

4. Open any suction and discharge valves andcheck supply vessel for minimum fluid level.

5. Inject a 4 MADC signal and apply 115 VAC powerto the actuator and start the pump motor.

6. Gradually increase input signal to 20 MADCwhile checking for leaks and correct pump/actuator performance (noisy orientation,overcurrent, jamming, etc.). If pump is installedoutdoors in temperatures below 40°F,intermittent actuator stalling may occur. This willnot cause any damage or an out of synccondition. To obtain maximum pump/actuatorperformance, it is recommended that ambienttemperatures above 40°F be maintained.

7. Inject a 4 MADC signal to bring the actuator to0% capacity. Remove power from the pumpmotor, correct any leaks as necessary andrecheck the oil level in the pump (refer to thepump manual for the correct oil grade and level).Be sure all covers are on tight. This is importantto maintain NEMA integrity and prevent liquidentry, which may cause damage to the pumpand the actuator.

8. Adjust capacity decal (3440) to line up withcapacity indicator ring (3412) while the pump isat zero percent capacity position. Replace thescale if it is damaged or hard to read.

9. Pump is ready for service.

OUTDOOR INSTALLATIONSSpecial consideration must be given when the pumpand actuator are used in outdoor service. Avoidlocating the pump and actuator in an area whereflooding or direct water runoff can occur.

Although the pump and actuator are designed foroutdoor service, condensation will form within theactuator housing as temperatures fluctuate,especially in sub-tropical or humid environments.

In all outdoor installations, a space heater shouldbe installed in the actuator enclosure, or the unitshould be heat traced such that a temperature of55-70°F can be maintained.

Properly sized space heaters are available fromNIKKISO Hydroflo®. Consult the factory or your localrepresentative for additional information.

PARTS ORDERING INSTRUCTIONS

Always have the complete NIKKISO Hydroflo®

pump model and serial number available whencontacting NIKKISO Pumps America, Inc. for partsor service. This information can be found on thenameplate mounted on the side of the pump.

Because of the complicated solid-state circuitrycontained in the control unit, we do notrecommend field servicing unless the necessarytools and test equipment are available.

Should it be necessary to send the pump andelectric capacity control to the factory for repair orservice, thoroughly flush the pump liquid end ofall process fluid, drain all hydraulic oil, pack securelyfor shipment, and call factory for a returnauthorization number. A material safety data sheet(MSDS) and a signed Return Goods Authorizationform will be required. Equipment received withoutreturn authorization number will not be accepted.
