Refer to Weights and Measures page 54 for Actuator weights.

Ensure the valve is secure before fitting the actuator as the combinationmaybe top heavy and therefore unstable.

If it is necessary to lift the actuator using mechanical lifting equipmentcertified slings should be attached as indicated in Fig.18a for vertical valveshafts and Fig.18b for horizontal shafts.

Trained and experienced personnel should ensure safe lifting particularlywhen mounting actuators at other angles.

WARNINGThe actuator should be fully supported until full valve shaft engagement isachieved and the actuator is secured to the valve flange.

A suitable mounting flange conforming to ISO 5210 or USA Standard MSSSP101 must be fitted to the valve.

Actuator to valve fixing must conform to Material Specification ISO Class8.8, yield strength 628 N/sq mm.

WARNINGDo not lift the actuator and valve combination via the actuator. Always liftthe valve/actuator assembly via the valve.Each assembly must be assessed on an individual basis for safe lifting.

Mounting the Actuator5

a) Fitting the Actuator and Base as Combined Unit. All Actuator Sizes

Fig. 19

Fit the machined drive nut into thethrust base as previouslydescribed, lower the actuator ontothe threaded valve stem, engage“hand” and wind the handwheel inthe opening direction to engagethe nut onto the stem. Continuewinding until the actuator is firmlydown on the valve flange. Wind twofurther turns, fit securing bolts andtighten fully.

b)Fitting Thrust Base to Valve. Actuator sizes :- 7 to 35 only

Fit the machined drive bush intothe thrust base as previouslydescribed. Remove the thrust basefrom the actuator, place it on thethreaded valve stem with theslotted end of the drive bushuppermost and turn it in theopening direction to engage thethread. Continue turning until thebase is positioned onto the valveflange. Fit securing bolts but do nottighten at this stage. Lower theactuator onto the thrust base and rotate the complete actuator until

the drive dogs on the actuatoroutput shaft engage into the drivenut. Actuator flange should now beflush with base flanges.

Fig. 20

Continue to turn actuator untilfixing holes align. Using boltssupplied fix actuator to thrust baseand tighten down. Open valve bytwo turns and firmly tighten downfixings onto valve flange.

Check that the mounting flange isat right angles to the input shaft,and that the drive bush fits theshaft and keyway with adequateaxial engagement. Engage “hand”,offer up actuator to the input shaftand turn handwheel to alignkeyway and key. Tighten mountingbolts.

Treat as for side mounting exceptthat when thrust is taken in theactuator, a thrust nut must be fittedabove the drive bush and securelytightened.

Ensure that sealing plug in centreof handwheel (or spindle covertube depending on which is fitted)is sealed with PTFE tape and fullytightened, ensuring that moisturedoes not pass down the centrecolumn of the actuator.

5.4 Handwheel Sealing

The IQM range of actuators aresuitable for modulating control dutyof up to 1200 starts per hour inaccordance with IEC 34-1 to S450%.IQM actuators have a dynamicbraking facility as standard. Ifmechanical overrun of the actuatorand valve prove to be excessive foraccurate control, the brake can beenabled by fitting a link to theactuator terminal block as indicatedby the wiring diagram. Withdynamic braking enabled, motorheating effects increase andtherefore the number of actuatorstarts should be reduced toprevent motor thermostat tripping.(Refer to publication E 410E for moreinformation).Commissioning of IQM rangeactuators is identical to thestandard IQ.(Refer to sections 7/8/9)

Consists of a lead screw assemblyarrangement attached to the baseof the actuator in order to provide alinear output stroke between 8mm(3/8in) minimum and 120mm (4 3/4in) maximum.The IQML can be supplied with orwithout a yoke mounting adaptor,this adaptor consists of four pillarsand a base flange to suit the valve.

5.5 IQM Modulating Actuators 5.6 IQML Linear Drive Unit 5.7 Adjusting Linear Stroke

Turn the actuator hand wheelclockwise, linear drive will go downtoward valve spindle, couple lineardrive to valve spindle.

Turn the tubular down stopclockwise into the actuator until itcomes to a mechanical stop. If thevalve must close onto its seat by“TORQUE ACTION” then back off(anti-clock) the down stop by onethird of one turn (equivalent to1mm). Run the lock nut down ontothe tubular down stop and tightenwith two spanners. There is no “upstop” (open) on the linear driveunit, the mechanical stop in thevalve will give this position. Refitthe top cover tube to thehandwheel using teflon tape toseal the thread.

The linear drive unit is pre-packedwith grease type Rocol MTS 1000,use this or an equivalent hightemperature bearing grease.

A grease Nipple is situated in thebase of the actuator to enable

lubrication of the lead screw.Periodically, dependant on usageand temperature, apply two pumpsof a grease gun.

6.5 Replacing Terminal Cover

The Rotork IQ Range of actuatorsis the first that enablescommissioning to be carried outwithout removing covers aftercabling has been completed.Setting torque, limit and otherfunctions is achieved by using theinfra-red Setting Tool. The SettingTool is certified Intrinsically Safe toallow commissioning in hazardousareas with power on.

All the commissioning functions arestored in non-volatile memory inthe actuator. The Setting Toolenables the user to view all thefunctions in turn via the actuatordisplay window. As each function isviewed its setting can be checkedand, if required, changed within thebounds of that function.The Setting procedure is dividedinto two stages:

1. Primary functions -Settings for end of travel Limit Actions, Torque Values, Limit Positions etc.

2. Secondary functions - Settings covering the control, indication and optional equipment functions.

All IQ actuator functions areconfigured before dispatch toRotork standard default settingsunless alternatives have beenspecified with the order. Shoulddifficulty be encountered duringcommissioning the defaultsettings can be re-instated,returning the actuatorconfiguration to its originalmanufactured state. Sitecommissioning can then beginagain. (See section 9.10 page 42)

The default function should beused with caution as settingsselected after manufacture may beessential for the safe operation ofthe valve and/or plant.

All IQ actuator functions are configured before dispatch to a set of Rotorkstandard (default) settings. If requested, alternatives specified with theorder will be used. When site commissioning using the setting tool takesplace, entered settings overwrite the Rotork defaults and these “Current”settings are used by the actuator for operation along with the remainingunadjusted defaults.

Should difficulty be encountered during commissioning the default settingscan be re-instated, returning the actuator configuration to its originalmanufactured state. Site commissioning must then begin again.

There are two levels of Default.D1 Rotork standard or Customers specified settings.D2 Rotork basic test settings.D3 Rotork only

NOTE: D1 will return the torque values to their default settings. The setlimit positions are not changed.D2 will reset the limit positions to 25 turns apart, the actuator being at the50% position. The set torque values are not changed.

The functions associated with the Folomatic and Pakscan options are notaltered by reinstating the defaults.The Interrupter timer option isunaffected by the D1 default but the D2 default will disable the option.Subsequent reinstating of D1 will re enable the timer but it will require allits functions resetting.

MaintenanceEvery Rotork actuator has beenfully tested before despatch to giveyears of trouble free operationproviding it is installed, sealed andcommissioned in accordance withthe instructions given in thispublication.The IQ actuator's unique doublesealed, non intrusive enclosureprovides complete protection forthe actuator components.Covers should not be removed forroutine inspection as this may bedetrimental to the future reliabilityof the actuator.

The electrical control module coveris bonded by the Rotork qualitycontrol seal. It should not beremoved as the module containsno site serviceable components.

Routine maintenance shouldinclude the following:* Check actuator to valve fixing

bolts for tightness.* Ensure valve stems and drive

nuts are clean and properly lubricated.

* If the motorised valve is rarely operated, a routine operating schedule should be set up.

* Replace actuator battery every 5 years.

The Actuator BatteryThe battery supports the actuatorposition updating circuits and theposition (LCD) display when themain power supply is turned off.It ensures the current position isupdated and displayed whenmanual operation takes place withthe main power turned off.The battery is not required tosupport the EEPROM memory.

Maintenance, Monitoringand Troubleshooting

A unique circuit has beenincorporated into the batteryfunction of the IQ, effectivelyreducing the overall drain andsignificantly increasing the batterylife.Tests show for a “typical” actuator, abattery life of 7 years can beexpected.Allowing for a conservativemargin, Rotork recommend thatthe battery should be replacedevery 5 years.

Battery level status indication isavailable as a standard feature(Refer to Help screens -10.1 page 46 andS contacts Section 9.2 page 28).

Battery ReplacementProceed as follows:The actuator battery is located in aseparately sealed compartment onthe main electrical control modulecover, to the left of the controlselector knobs. If the actuator islocated in a hazardous area a “hotwork” permit must be obtainedunless the actuator can be removedto a non hazardous location.

It is recommended that the Batteryis replaced with the mains powerturned ON.

For actuators shipped before 1998with the optional Data-Logger fittedit is essential that batteryreplacement is undertaken withmain power on, otherwise loggeddata will be lost. Alternatively,Logged Data can be downloadedand stored using the RotorkCommunicator (Refer to PublicationE172E for information).

For actuators shipped after 1997the battery can be changed withthe main power on or off.

* Undo the 4 caphead screws in the battery box cover and remove battery.Used batteries should be disposed of in accordance with the relevant regulations.

* Fit replacement battery: For CENELEC Actuator enclosures use a Duracell Procell MN 1604 9 volt 6LR61 Alkaline battery ONLY.

For Watertight (WT)- FM - CSAactuator enclosures Rotorkrecommend the use of an UltracellLithium U9VL 9 volt battery as ithas a long shelf life but anyequivalent may be used.

* Replace battery box cover. Ensure cover 'O' ring is in goodcondition and correctly fitted.

* Reset Limit Closed and Limit Open positions.

IQ Actuators do not require regularoil changes.

(Refer to Weights & measures section 11, page 54)

MonitoringThe IQ range of actuators are theworlds first to incorporate real time,instantaneous torque + positionmonitoring as standard.Torque + position can be used tomonitor valve performance duringoperation. The effect of processchanges (differential pressure etc)can easily be evaluated. Tightspots in valve travel can bepinpointed as well as gaugingtorque developed through strokefor Torque Value Setting (See pages22 , 23).Using the Setting Tool, the displaycan be set to indicate torque andposition.With the actuator displaying currentposition and selected to local orstop.

Press the key

The display will split, the topindicating the instantaneoustorque, (% rated), the bottomindicating the measured position(% open).

Example shows 19% (of rated)torque at 50% open position.Display torque range: [00] - [99] %of rated in 1% increments. Forvalues of torque above 99% thedisplay will indicate [HI].Display position range:[ ][ ] valve closed[00] - [99] % open[ ] valve openFor a stationary actuator thedisplay will capture the lastmeasured value.

To keep the torque + positiondisplay active press or keys.The display will remain active forapproximately 5 minutes from thelast key operation.

TroubleshootingThe IQ range of actuators are theworlds first that can becommissioned and interrogatedwithout removing electrical covers.Help screen diagnostics enablefast and complete fault finding tobe carried out.

With power On, the actuatordisplay is not backlit. Positionindicator lamp not illuminated.With mains power on, the actuatorsdisplay should be backlit. (Refer to 3.3 - the Actuator Display.)

Check that 3 phase supply isavailable and is of the correctvoltage as stated on the actuatornameplate. Measure Voltage phaseto phase across terminals 1, 2 & 3of the actuator terminal bung.

With power Off, the actuatordoes not display position.With mains power off the actuatorbattery supports position indicationliquid crystal display only. (Refer to 3.3 - the Actuator Display.)

If the display is blank the actuatorbattery must be replaced and limitreset.(Refer to Section 10, Page 44 TheActuator Battery.)

With the actuator powered up andLocal or Stop control selected, sixhelp displays can be accessedusing the Setting Tool. (Refer to Section 9 fig 30 page 26 fortheir location.)

With remote selected press the key. The help screens will bedisplayed.

Each display uses bars to indicatethe status of a particular control orindication function. Each bar reactsto changes in the status of itsactuator function by turning “on” orturning “off”

For troubleshooting, access thefollowing Help displays and refer totext:H1- Factors inhibiting electrical

operation and monitoring direction of movement.

H2 - Monitor Local and Remote control inputs to the actuator.

H3 - Monitor remote indication outputs derived by the actuator.

H4 - Monitor the actuators positionsensing devices.

H5 - Monitor the actuators batterystatus and position limit status.

H6 - Torque Trip, Flux and mains power supply monitoring.

Help screen bars marked areundefined and may be ON, OFF orflashing.

H6 Torque Trip, Flux & MainsPower Supply Monitoring

On power up the actuatorautomatically tests its vitaloperational circuits and memorydevices to ensure correctoperation.In the unlikely event of a deviceproblem the IQ diagnoses thecause and will automaticallypresent this information in the formof Help Screen 7 Alarm display.Electrical operation can beinhibited to prevent possibledamage to the actuator and valve.The problem can then beaccurately investigated andcorrected by maintenancepersonnel.

ASTD is carried out every timemains power is applied and only inthe event of a problem will H7Alarm be displayed.Help Screen 7 therefore cannot beaccessed using the Setting Tool.

After circuits and communicationare checked, ASTD tests for thefollowing conditions:

* Actuator Position Error - the actuator current position is in error

* Black Out - the actuator was subjected to a combined mains supply and actuator battery supply failure (Refer to The Actuator Battery p44)

* Actuator configuration Error - theactuator configuration (settings) are in error.

Should any one (or combination) ofthese tests fail Operation will beinhibited *, and an alarm displayed:the display lamps will flash and theappropriate H7 display will indicatethe cause by using a numberbetween 1 and 7.Remote indication of inhibitedoperation will be indicated by themonitor relay.

NOTE: Operation will be inhibited astandard. Whether a combinedmains and battery supply failurewill inhibit operation is determinedby the setting of OS (Refer to 9.9Inhibit Operation After PowerLoss p42).

The following table interprets allcombinations of H7 alarm displays:

H7 - 1 = Configuration error alarmH7 - 2 = Position error alarmH7 - 3 = Config error + Position
